Probabilistic Techno-Economic Design of Isolated Microgrid

Isolated microgrid (MG) proved its potential to electrify the remote community through the cheaper and greener renewable energy alternatives with higher reliability than the weak grid. The goal of universal electricity access and the climate change mitigation paves the way for many public/private owned microgrids in remote areas. Having in mind various uncertainties associated with the design parameters of the MG (e.g., temperature, irradiation, load), this paper presents a probabilistic approach for optimal sizing and techno-economic assessment of the PV-based MG. The potential environmental impact of the isolated MG is taken into account by considering both, the PV/Battery, and more conventional PV/Battery/Diesel Generator configuration. The effectiveness of multi-year data over the single year data in the probabilistic approach is demonstrated. The probabilistic techno-economic analysis of different configurations facilitates informed decision making regarding the configuration and size of MG components while meeting the reliability of supply and environmental constraints. The feasibility and affordability of the configurations are demonstrated through the distribution of net present cost, levelized cost of energy and the unmet load percentage.

Design Optimization of Components for Additive Manufacturing-Repair: An Exploration of Artificial Neural Network Requirements and Application

The integration of artificial intelligence (AI) in additive manufacturing (AM) technology is currently a promising and leading area of research for component repair and restoration. The Issues of high cost and time consumption for AM repair have been a subject of discussion among researchers in this field of study. Moreover, the potential challenges in dealing with complex components for repair and restoration in the (AM) domain require the establishment of a critical technical platform based on hybrid (AI). At this point, the proposed optimization method must cover all important parameters for the complex configuration of structural components under restoration. For the purpose of this study, a design optimization framework was developed using a MATLAB-SIMULINK mathematical model for AM solution purposes by improving the functionality and integration of monitoring. This improvement is based on facilitating the real-time identification of failures with accuracy and giving a clear monitoring vision according to the intended targets like geometric distortions, residual stresses evaluation, and defect characterization. The improvement involves overcoming a number of challenges such as the pre-fabrication stage by expanding the data repository besides offering a theoretical set of algorithmic with some options that improve the current procedure. Also, this study will conclude and suggest a further framework and new knowledge for restoration and product life cycle extension. This developed ANN can be used at the real pace of modeling the MATLAB-Simulink system and merged with another suitable algorithm to form a hybrid ANN. This model development using a neural network has attained a good manipulation of AM. The predicted data from ANN model that was determined and achieved in this study can be used to facilitate and enhance any further study as base knowledge in merging the ANN with another AI to form a hybrid algorithm.

Research on the thermal management safety of the fast charging power battery management system

In order to solve the problem of excessive heat generation in electric vehicle power batteries under extreme fast charging conditions, we have established a heat generation and thermal management system model for fast charging power batteries. The heat transfer efficiency of the power battery thermal management system under different environmental temperatures and experimental conditions was studied. The factors affecting the thermal management system of the power battery were analyzed by analyzing the speed and cooling capacity of the air conditioning compressor, the control parameters of the model and selecting the most suitable component configuration parameters by optimizing, a thermal management system has been designed to meet the cooling requirements of the power battery under different environmental temperatures and high-speed operating conditions. Through simulation and comparison of experimental data under different environmental temperatures, it is shown that the optimized fast charging power battery system can meet the design objectives under different environmental temperatures, and the battery temperature is always controlled within a reasonable temperature range. The designed power battery heat management system has good safety and robustness.

Control Systems Synthesis of Maximum Robust Stability Degree Based on Vertex Critical Root Diagrams

The article solves the problem of operative selection of the redundant onboard equipment complex components configuration of the suitable in the current operating conditionаs in the interests of ensuring high fault tolerance of the complex, as well as achieving other operational and technical characteristics. The basis of the redundancy management system of the complex consists of configuration supervisors — as program subjects according to the number of its competitive configurations of heterogeneous and nonuniform equipment worked out in advance. The choice of the preferred configuration is proposed to be carried out by performing multi-level arbitration, which includes two phases of paired arbitration of computers and paired arbitration of configuration. It is proposed to include the means of both types of arbitration in each configuration supervisor, which ensures its self-sufficiency when participating in a competitive selection. The second part of the article is devoted to the computer’s arbitration for the implementation of redundancy management functions. The approach is applicable to a computing environment with many comparable computing devices and contains 2 phases. In the first phase, a preliminary selection of a competing pair of computers — as applicants for the implementation of redundancy management functions in them is carried out. In the break between the phases, the pair computers implement the procedures for pair arbitration of configurations given in the first part of the article. In the second phase, the final choice of the -computer is made, in which the supervisor who won the arbitration will be implemented. In order to achieve the maximum possible centralization of selection procedures and, as a consequence, the exclusion of " bottlenecks" in terms of reliability of places, additionally proposed: the organization of secure data exchange between computers based on distributed registry technology; the procedure of paired arbitration of computers, consisting in mutual cross-validation of dominant supervisors of a pre-allocated pair by comparing preference matrices, including information parcels of arbitration objects. A methodological example that demonstrates the features of the system functioning in the conditions of computers degradation is given. The proposed approach can be used to solve the problems of reconfiguration control of heterogeneous computing facilities of technical objects on-board equipment complexes.

Thermodynamic analysis and optimization of liquid air power plant integrated with parabolic trough solar collectors

ABSTRACT As to investigate the impact of parabolic trough collector optical characteristics on the comprehensive performance of solar-driven liquid-gas energy storage power plants, this study establishes a mathematical analysis model for a liquid-gas energy storage power plant with a parabolic trough collector. The effects of direct irradiance, collector tracking mode, and component configuration on collector efficiency, round-trip efficiency, and exergy efficiency are analyzed. The results show that when the direct irradiance exceeds 400 W/m2, the round-trip efficiency of the system decreases while the exergy efficiency increases. For every 100 W/m2 increase in irradiance, the round-trip efficiency decreases by 1.54%, and the exergy efficiency increases by 2.36%. The north-south axis tracking mode is superior to the east-west axis tracking mode and dual-axis tracking mode. The component configuration improves the collector efficiency and round-trip efficiency but decreases the thermal efficiency. In low irradiance conditions (direct irradiance less than or equal to 400 W/m2), the system performance is optimal when the collector optical efficiency is maintained at 74%. Under these conditions, the system achieves a maximum net energy output of 495.12 kW·s/kg, the exergy efficiency of 54.5%, and the round-trip efficiency of 18.96%. In high irradiance conditions (direct irradiance greater than 400 W/m2), a 10% increase in collector optical efficiency leads to a 1.94 kW·s/kg decrease in net energy output, a 3.14% decrease in exergy efficiency, and a 0.05% decrease in round-trip efficiency.

BEELINE: BilevEl dEcomposition aLgorithm for synthesis of Industrial eNergy systEms

Energy transition to a more sustainable basis is the most significant and complex challenge facing industry. On most industrial sites, the largest single energy user is the utility system that produces the heat and power necessary for the site. The heavy reliance of current utility systems on fossil fuels and the requirement of strategic measures to ensure a sustainable future has prompted researchers to explore different energy sources, technologies and pathways for evolving existing systems to a sustainable basis for future utility systems. Whether based on renewable or non-renewable energy sources, it is essential to minimize energy demand and mitigate emissions. The present work focuses on developing cost-effective solutions for the synthesis of process utility systems, considering site-wide energy integration. This will provide a platform in future work for the efficient introduction of renewable energy sources in the transition to sustainable systems. Utility system performance is generally determined by system configuration and operational load. Steam mains selection, in terms of pressures and superheating have a critical role in the utility system performance and site energy integration. Therefore, the synthesis of energy-efficient utility systems involves optimizing the configuration of utility components and number and operating conditions of steam mains simultaneously. Due to nonlinearities and non-convexities from underlying physics and binary decisions involved, the resulting Mixed-Integer Non-Linear Problem (MINLP) presents challenges for advanced state-of-art solvers to solve real-world problems. In past work, a number of important practical issues have been oversimplified in order to make the solution tractable. However, the oversimplifications also lead to misleading results. In this research, a mathematical formulation for simultaneous optimization of comprehensive utility system configurations and operating conditions is for the first time combined with more realistic steam system configurations and operating conditions to represent the utility systems. Its framework is constructed via a bilevel decomposition algorithm based on piecewise MILP relaxation, McCormick relaxation, and linearization of steam properties. In addition, the solution pool feature of the CPLEX solver is incorporated to enhance the performance and convergence of the algorithm. This work presents the fundamental problem formulation that has not been sufficiently addressed previously. Indeed, this methodology sets out the basis for synthesizing energy-efficient utility systems for the future and allows for many energy conversion technologies and sources to be added to the framework that have previously not been possible to include.

Co/VN heterojunction anchored on multi-dimensional N-doped carbon for high-performance zinc–air batteries

Thanks to high electroconductivity and excellent electrochemical durability, the vanadium nitride (VN) is gradually developed as an electrocatalyst. However, the oxygen dissociation ability of VN species is usually weak due to the lack of d-orbital electrons in the vanadium. Herein, Co nanoparticles with abundant 3d-orbital electrons were utilized to construct the heterojunction with the VN (Co/VN), which anchored on the multi-dimensional N-doped carbon (CoVN/NC) for oxygen reduction reaction (ORR). The heterogeneous interface within the Co/VN increased more active sites and was conducive to adsorbing more O-containing intermediates. The oxygen dissociation ability of intermediates was improved on the VN surface. Based on “3d-orbital electron complementary effect”, the Co nanoparticles transferred d-orbit electrons to the VN and regulated the electronic configuration of VN components. The continuity of the V 3dz2 orbitals within the Co/VN was enhanced near the Fermi level, which promoted the formation of strong σ bonds between the CoVN/NC and O pz orbitals. Therefore, the O–O bond of O2 was more easily broken on the CoVN/NC surface. The CoVN/NC displayed the half-wave potential of 0.85 V for ORR. The zinc-air battery with the CoVN/NC possessed a power density of 200.7 mW cm−2 and a cycle stability of 180 h. This work would provide a practical reference for improving electrocatalytic activities of VN species.

How Does the Residential Complex Regulate Residents’ Behaviour? An Empirical Study to Identify Influential Components of Human Territoriality on Social Interaction

Although urbanisation and urban land limitations are prevalent, residential complexes are seldom discussed as a means of compartmentalising social interactions and contributing to residents’ social interactions. Due to the spatial orientation of social interactions, semi-public spaces in these buildings are unable to host residents’ interactions due to a lack of appropriate arrangements/establishment of tangible and visible objects. The influential components, however, have rarely been identified in residential complexes. To fill this gap, using the theory of human territoriality, the current study explores the influential physical components of human territorialities in semi-public spaces in four residential complexes and investigates whether a significant relationship exists between human territorialities’ physical components and social interactions. This study collected data from 264 residents of four residential complexes with different spatial configuration layouts. Pearson correlation and Spearman’s rank correlation are used to evaluate linear and monotonic relationships between study variables. The correlation between spatial configurations of physical components and residents’ interactions confirms that spatial configurations influence residents’ use of semi-public spaces. Social interaction can, therefore, be improved through green space, brightness, accessibility, and furniture in common areas. The findings prove that residential complexes with clustered arrangements have not performed well in creating social interaction due to the lack of defined spaces and territories for people, but multi-core, mixed, and linear complexes that define several open and semi-open spaces have been more successful in the amount of social interaction of residents. This study is one of the first to identify the influential components using the integration of residents’ perceptions and spatial configuration.

Ultrasound-Auxiliary Preparation of Antifouling Cu-Enriched Titanium Oxide Ceramic Layer

The limited antifouling capability of Ti-based components could jeopardize their applications in petroleum engineering. In this work, a Cu-enriched TiO2 coating has been fabricated using an ultrasound-auxiliary micro-arc oxidation (UMAO) method. The Cu enrichment of TiO2 affects its morphology, phase component and chemical configuration, leading to the slightly enhanced corrosion resistance of the Cu-enriched TiO2 coating relative to that free of Cu. Finally, the antifouling capability against sulphate-reducing bacteria (SRB) is significantly improved by preventing the formation of biofilm after the Cu enrichment of TiO2, which potentially widens its application in petroleum engineering.

The capacitated location problem of precast concrete component factory

The location and capacity of precast concrete component factories (PC component factories) are not only the key factors for manufacturers to gain competitive advantage, but also the important factors affecting the operational efficiency of the prefabricated construction supply chain. This paper takes the capacitated location problem of PC component factories as the research object. Drawing on the model of traditional capacitated plant location problem, the model of capacitated location problem of PC component factories is constructed by setting the optional production scale by stages. According to the characteristics of this model, the optimal strategy of location is determined by using the Tabu search algorithm. Taking the location problem of PC component factory in the Beijing-Tianjin-Hebei region as the object, the calculation example is designed, in which the influence of the distance parameters on the results of location problem is analyzed. The results can make the configuration of regional PC component factories more reasonable and balanced.

Alternative Internal Configurations for Enhancing Heat Transfer in Telecommunication Cabinets

Telecommunication systems have become a critical part of society which enables connectivity to many essential and trivial services. Consequently, telecommunication equipment is housed in cabinets to protect the electronics from a variety of hazards; one of which is temperature-related failure. Current practices use a notable amount of power for the thermal management of telecommunication cabinets which can be reduced by considering alternative methods of cooling. In this paper, experiments were carried out to investigate the effectiveness of different internal mounting configurations of electronic components on the thermal performance of a telecommunication cabinet. The investigation tested inclinations (0–90°), different staggered offsets (0–50 mm), changing stream-wise spacing (29–108 mm), and fan speed (with a Reynolds number in the range of 1604 to 5539). The experimental study revealed that heat transfer was enhanced by 9.99% by altering component inclination to 90°, 25.90% by increasing stream-wise spacing from 29 mm to 108 mm, and 36.02% by increasing the Reynolds number from 1604 to 5539. However, the staggered arrangement of internal components decreased Nu by 3.26% for the natural convection condition but increased by 5.69% for the forced convection condition over the tested range and increasing the centre offset of the staggered components with respect to the cabinet did not influence Nu in any significant manner. Natural convection and forced convection also had notable influence on the heat transfer rate. Hence it was seen that alternative internal configurations positively influence heat transfer in telecommunication cabinets for the cases studied.

Evaluation of various substances and trap component configurations to increase mosquito collections in Biogents Gravid Aedes traps.

Two independent studies were conducted in northeastern Florida to determine if Biogents Gravid Aedes Trap (GAT) mosquito collections could be enhanced with a variety of substances and structural configurations. The first study baited GATs with either: 1) an infusion of mixed Southern live oak leaf (Quercus virginiana) and slash pine needle (Pinus elliottii) litter, 2) Biogents Lure (BG Lure), 3) yeast-derived carbon dioxide), 4) yeast-derived carbon dioxide+ BG Lure, or 5) a combination of all three. Nine mosquito species were collected from traps in the first study with Psorophora ferox>Culex nigripalpus>Aedes aegypti>Cx. quinquefasciatus as the top four most abundantly collected species. No significant difference in mosquito abundance was observed among these species among treatments. However, when the overall number of mosquitoes for all nine species was pooled, GATs baited with the combination of yeast-derived carbon dioxide + BG Lure + leaf infusion numerically collected the greatest number of individuals compared with the other four treatments. The second study evaluated the separate and combined attractiveness of individual GAT structural components/configurations with and without Southern live oak leaf litter infusion and BG-Lure. Aedes albopictus, Ae. aegypti, Anopheles quadrimaculatus, and Cx. quinquefasciatus were collected from all these traps in the second study. Results generally revealed that the current commercially available GAT configuration consisting of a screened translucent top (with BG-Lure) fitted into the black reservoir baited with oak leaf infusion remained the most attractive combination for collecting northeastern Florida mosquitoes.

Room-Temperature Self-Healing Conductive Elastomers for Modular Assembly as a Microfluidic Electrochemical Biosensing Platform for the Detection of Colorectal Cancer Exosomes.

Modular components for rapid assembly of microfluidics must put extra effort into solving leakage and alignment problems between individual modules. Here, we demonstrate a conductive elastomer with self-healing properties and propose a modular microfluidic component configuration system that utilizes self-healing without needing external interfaces as an alternative to the traditional chip form. Specifically, dual dynamic covalent bond crosslinks (imine and borate ester bonds) established between Polyurethane (PU) and 2-Formylbenzeneboronic acid (2-FPBA) are the key to a hard room-temperature self-healing elastomeric substrate PP (PU/2-FPBA). An MG (MXene/GO) conductive network with stable layer spacing (Al-O bonds) obtained from MXene and graphene oxide (GO) by in situ reduction of metals confers photothermal conductivity to PP. One-step liquid molding obtained a standardized modular component library of puzzle shapes from PP and MGPP (MG/PP). The exosomes were used to validate the performance of the constructed microfluidic electrochemical biosensing platform. The device has a wide detection range (50-105 particles/μL) and a low limit of detection (LOD) (42 particles/μL) (S/N = 3), providing a disposable, reusable, cost-effective, and rapid analysis platform for quantitative detection of colorectal cancer exosomes. In addition, to our knowledge, this is the first exploration of self-healing conductive elastomers for a modular microfluidic electrochemical biosensing platform.

Parametric FE model for the thermal and hydraulic optimization of a Plasma Facing Component equipped with sacrificial lattice armours for First Wall limiter application in EU-DEMO fusion reactor

In EU DEMO reactor, components exposed to burning plasma are subject to extreme conditions due to short and extremely strong thermal transients, which impact their lifetime and functional integrity. Due to this energy, surface vaporization, melting and resolidification may lead to excessive degradation and frequent extraordinary maintenance. For this reason, in view of DEMO and future reactors, one of the most challenging aspects of fusion reactor technology is to devise FW (First Wall) sacrificial limiters that will prevent excessive damage of the otherwise un-shadowed FW modules during extreme plasma transients. Rather than dense armours, W-lattice structures can contribute to this purpose, since they can be optimized to have a thermal conductivity that ensures, at steady state, effective heat dissipation and at the same time a thermal diffusivity that, in transients, maximizes the vapour shielding effect.The objective of the research activity here presented was to identify, through a parametric model, the optimized component configurations to be considered for this sacrificial limiter, in order to maximize its functional effectiveness. Based on the two elementary cell morphologies developed in previous studies, the parametric model allowed to investigate the combinations of relevant parameters, above all component size and geometries, armour/heat sink materials and thicknesses. Thermal optimization regarded both normal operation and two possible transient scenarios: an unmitigated plasma disruption or the Ramp Down phase. By scanning all possible combinations of parameters, those able to provide the best performances thus satisfying the user-defined functional requirements of the limiter have been identified. The thermal optimization phase was followed by CFD (Computational Fluid Dynamics) analyses in order to evaluate the potential integration of the limiter cooling circuits within the divertor Primary Heat Transfer System (PHTS) from a thermal–hydraulic point of view.

Rethinking Abiogenesis: Part III, Meaning in the Light of Complexity, Information, and Simplification

This article concludes a three-part series on abiogenesis that suggests meaningful configurations of organic components can arise spontaneously, leading to organisms that successfully survive and reproduce. While the complexity of the disorganized abiotic world makes it appear to some that such a feat of organization would require the nonnatural intervention of an intelligent mind (including but not limited to supernatural intervention), we suggest that careful considerations of thermodynamics and information lead to the plausibility of a natural occurrence. No specific, complete pathway for abiogenesis has yet been identified, but the fundamental processes that enable such a path can be articulated more clearly now than ever before as a result of new and continuing research in multiple disciplines. This concluding article centers on the way in which complex states of molecular organic information can be generated to produce the most meaningful configurations.

An Investigation Into Slogan Design On Creating Slogan–Brand Alignment

As the COVID-19 pandemic has reshaped consumers’ perceptions of brand messaging, advertisers are revisiting their messages and investing more heavily to strengthen brand identity alignment. Brand identity alignment is the configuration of all semiotic components— brand name, logo, and slogan—used to support a company’s desired brand image. With semiotic theory and congruence theory used as foundations, this paper examines attributes of slogans that affect their alignment with brand identity. Using data from a large-scale field study, followed by a validation study using senior advertising managers, the authors find that message clarity and creativity enhance, whereas a jingle in a slogan message reduces, the slogan–brand alignment.

Advances in material phase change modelling approach for EU-DEMO limiter’s plasma-facing components

Within the EU-DEMO first wall protection framework, work on limiter’s plasma-facing component design has started under plasma disruptive events (Richiusa et al., 2022). Starting from the rationale behind the TARTIFL&TTE software (Richiusa et al., 2022), this companion paper describes the progress on the engineering modelling of the plasma-facing material phase change under high heat flux, with the aid of COMSOL Multiphysics® software. The aim is to develop a reliable technique which can be used by designers for predicting how much of the solid armour undergoes phase change. This helps satisfy requirements for actively cooled components, such as at which armour depth safely locating the cooling system, and if its design can safely handle the heat transfer in the resulting component configuration after the disruption is extinguished. A few changes to the driving idea in Richiusa et al. (2022) will be also highlighted.The multiphysics software allows us to implement a 1D model which can be extended to 2D/3D geometries subjected to both uniform and non-uniform heat flux. It also offers the capability of conjugated heat transfer in solids and liquids by coupling the two different domains. Although this multiphysics approach is also investigated, no effort in melting layer motion modelling is done. Therefore, the equivalent way of validating this approach while reducing its computational time is working with one single solid domain, within which any liquid phase changes are tracked by an apparent heat capacity formulation. The vapour domain is not modelled. The material removal due to the evaporative mass flux is modelled by means of moving mesh frames which push the recessing liquid interface backwards according to gas kinetics-driven boundary conditions. The melt pool is not removed during the transient. Mass balance considerations drive the liquid-to-vapour interface velocity.The 3D Multiphisics implementation (3D-TARTIFL&TTE), is here supported by a benchmark activity and an application to the limiter’s plasma-facing armour, whose preferred chosen thickness is 20 mm.

Optimal energy scheduling of a standalone rural microgrid for reliable power generation using renewable energy resources

ABSTRACT Rural villages can be electrified using renewable power sources for the area to grow effectively. Microgrids powered by renewable energy is more environmentally friendly and practical choices for electrifying rural areas. This study attempts to ascertain the technological and financial viability of an autonomous hybrid energy source for a remote Indian area in order to provide a reliable power supply. The region’s load requirements can be met with the help of a solar energy system, biogas, wind energy, diesel generators, and batteries. Differential evaluation (DE) is used to optimize the proposed microgrid for grid-independent operation. The system’s ultimate objective is to reduce energy costs and recommend workable component configurations. Particle swarm optimization (PSO) and the genetic algorithm (GA) are used to compare the DE findings. The finding suggested the optimal energy cost of 0.22 $/kWh, a net current cost of $5,18,656, and a capital cost of $8,50,774. DE’s total net present cost is 4.3% less than PSO and 5.2% less than GA. However, it has been determined that the recommended approach is more practical and affordable for electrifying rural areas.

Simulation study of a heat pump drying system using a solar assisted flash tank vapor injection cycle

Heat pumps are widely used in many fields due to their high efficiency and energy saving potential. However, the application of single-stage vapor-compression heat pump dryer is limited due to low drying temperature and the decreasing reliability for hightemperaturedrying. In order to apply heat pump to high temperature drying, a heat pump drying system using a solar assisted flash tank vapor injection cycle (HPDS-SFVIC) is presented. This system allows the solar collector to absorb solar energy at a lower temperature and achieves significant improvement of heating capacity and drying temperature. The effects of component configuration and various operating conditions on the drying system with open, bypass, and closed air circulation loop are evaluated, respectively. The results show that under a typical operating condition, the proposed cycle achieves great performance improvement of 21.8% and 75.8% in both the heating coefficient of performance (COPh) and heating capacity, compared with the conventional cycle. Utilization of solar energy is advantageous to provide higher air temperature for drying. With increased solar radiation intensity and collector area, heating capacity and drying temperature can be improved, while COPh remains constant as 5.0–5.2. When the drying system provides dry air at 65 °C stably, it saves 27.8%–41.7% of power consumption, and COPh is improved by 41.2%–62.1% on average.

Hydrothermal synthesis and electrochemical performance of GNPs-doped MgFe2O4 electrodes for supercapacitors

This study sought to determine the effect of graphene on the electrochemical performance of MgFe2O4. The electrode preparation was done directly on the nickel foam surface using a hydrothermal technique. The crystallographic, morphological, and chemical configurations of the electrode components were investigated using XRD, FTIR, XPS, SEM, and TEM. Cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectrometry (EIS) were used to evaluate its electrochemical characteristics. The findings of the characterization demonstrate that MgFe2O4 was successfully synthesized with GNPs in a porous structure on a Ni foam surface. The electrochemical experiments show that the greatest specific capacitance (Cs) value found is 828 mF/cm2 at 1 mA current. At the same time, its stability after 1500 cycles at 4 mA was observed to be 136%, and its energy-power densities were calculated to be 28.75 mWh/cm2 and 200 mW/cm2. The Cs value in this study is roughly 242% higher than pure MgFe2O4 and 95% higher than MgFe2O4/GNPs in the literature, which is a significant effect of GNPs.
