Harnessing diurnal dynamics: Deciphering the interplay of light cycles on algal-bacterial membrane bioreactors

Light profoundly modulates the algal-bacterial membrane bioreactor (algal-bacterial MBR) performance. Yet, its outdoor deployment grapples with the inherent diurnal cycle of sunlight, engendering suboptimal light conditions. The adaptability of such systems to these fluctuating light conditions and their implications for practical outdoor applications remained an under-explored frontier. In response, this study meticulously scrutinized two laboratory-scale algal-bacterial MBRs under varying light regimes: a 24-h continuous and a 12-h cyclic illumination. Over 70 days, continuous illumination was observed to yield superior biomass production and total nitrogen and total phosphorus removal efficiencies compared to its cyclic counterpart. Contrarily, when focusing on membrane fouling, the 12-h cyclic illumination exhibited lower membrane fouling. The spectral analyses coupled with adhesion ability evaluation, traced the enhanced membrane fouling under continuous illumination to the elevated organics and heightened adhesive properties of the flocs. Given the tangible benefits of reduced membrane fouling and the potential harnessing of solar radiation, the 12-h cyclic illumination emerges as an economically astute operational paradigm for algal-bacterial MBRs. The significance of this study is to promote the application of algal-bacterial MBR in sewage treatment and provide robust support for the development of green technology in the future.

Equity Investments and Environmental Pressure: The Role of Venture Capital

This study investigates the global relationship between venture capital (VC) investments and environmental pressure in order to contribute to the literature on the influence of venture capital on sustainable development. Using a unique dataset covering VC activity and CO2 intensity in 131 countries from 2011 to 2021, the study employs a revised STIRPAT model—a stochastic model for assessing the environmental impact of human activities. The aim is to examine the potential negative correlation between VC investments and CO2 intensity. This motivation stems from previous findings, indicating that increased VC investments spur the diffusion of eco-efficient technologies. The main results affirm a significant negative correlation between VC investments and CO2 intensity, even after controlling for relevant variables and potential confounding factors (e.g., foreign direct investments), country, and year fixed effects, and addressing potential endogeneity through lagging independent variables. Exploring heterogeneity in the baseline results reveals that these findings are consistent only for VC investments in the Asia-Pacific region, in emerging and developing economies, and in areas where they can contribute more to the development of green technologies and innovations. This suggests that VC activity may impact environmental intensity primarily in countries where emission regulations are less stringent or where existing technologies exhibit lower efficiency in terms of energy consumption.

Electrosynthesis and Performance of Homogeneously Mesoporous Ni-Rich Ni-Pt Thin Films for Efficient Hydrogen Evolution Reaction in Acidic Media

The development of green hydrogen technology requires abundant electrocatalyst materials to (partially) replace costly platinum while maintaining the catalytic efficiency and durability. Nickel is an excellent choice for the partial replacement of Pt for water splitting, and is widely used for electrocatalysis in alkaline media. Although Ni cannot provide an activity identical to Pt, specific nanostructures aimed at a high surface-to-volume ratio, such as nanoporous structures, can significantly improve catalytic efficiency. However, in acidic media, the use of non-noble metals for electrocatalysis requires extensive durability tests to confirm the stability of the alloy. Additionally, the impact of hydrogen itself is often overlooked, as hydrogen is known to cause hydrogen embrittlement in Ni and its alloys.This contribution deals with the synthesis of a homogeneously mesoporous Ni-Pt alloy with high catalytic efficiency (Fig. 1). By electrodeposition from aqueous media, Ni-rich Ni-Pt alloy thin films are synthesised in a wide compositional range (between 60 and 99 at% Ni), depending on the deposition potential. The addition of the amphiphilic block copolymer Pluronic P-123 to the electrolyte formulation enables a micelle-assisted deposition process, resulting in films with homogeneous porosity with an approximate pore size of 10 nm irrespective of composition. Moreover, all thin films are single-phase and nanocrystalline [1], and show excellent performance under hydrogen evolution reaction (HER) in acidic media [2].As determined by Rutherford backscattering (RBS), the as-deposited Ni-Pt thin films with film thickness between 180 nm and 260 nm exhibit Pt enrichment at the surface of 1-2 nm in depth, after which Ni and Pt exhibit constant composition over depth. After hydrogen evolution in 0.5 M H2SO4, a gradient in Ni/Pt ratio over the film thickness is established, indicating preferential leaching of Ni into the electrolyte, and resulting in higher Pt content at the surface. Due to the porosity of the thin films, this leaching affects the entire film thickness. A chronopotentiometric durability test (24 h) reveals that the overpotential stabilises over time, indicating that the leaching of Ni is suppressed once a certain Pt/Ni ratio is attained in the thin films. In addition, the HER electrocatalysis is accompanied by a significant hydrogen uptake, determined by elastic recoil detection analysis (ERDA). Depending on the electrodeposition parameters, the as-deposited thin films already exhibit significant hydrogen concentrations between 2 and 10 at%. After the HER durability test, local cracking is observed by SEM, related to an excess of hydrogen in the thin films. Despite the cracking, no significant detachment of the films from the substrate is observed. The hydrogen contained in the films is assumed to be interstitial and does not affect the metallic nature of the Ni-Pt films. An X-ray photoelectron spectroscopy (XPS) post-analysis shows that the fraction of metallic Ni with respect to Ni in higher oxidation states is higher after exposure to the HER than for the as-prepared surface.

Impact of Investments in Green Technologies on Energy Security and Sustainable Development in the Future

One of the key areas of technological development in the world is the development of the so-called green technologies, which allow to ensure the required level of economic growth without creating additional environmental risks. In recent years, green investments in general, and green bonds, in particular, have become an effective tool for financing green projects. The purpose of the study was to determine the impact of the development of green technologies on energy security and sustainable development of energy technologies. To achieve this goal, the following tasks were solved: the essence and main directions of development of investments in green technologies in the modern investment space were determined; the volume of investments in green technologies in the world was estimated; possible directions of influence of investments in green technologies on energy security were outlined. It is established that green bonds and green investments in general can attract investors and create prerequisites for effective ensuring a sufficient level of environmental safety. It is also noted that ESG criteria are increasingly penetrating the financial sector. The emergence of green investments is associated with growing requirements for environmental friendliness of production and corporate social responsibility. According to market participants, over the next five years, many of the world's largest companies will add ESG ratings to traditional credit ratings and metrics. In general, analysing the effectiveness of investments in green technologies will help to make informed decisions and choose optimal development strategies that help to reduce the negative impact on the environment and increase the competitiveness of companies in the global market. The study concluded that investments in green technologies have potential opportunities for companies in various industries, but the success of such investments depends on a thorough financial assessment, risk management, and long-term development strategy.

Lifetime prediction and aging mechanism of unplasticized polyvinyl chloride filled with calcium carbonate under long-term thermal and oxidative conditions

The successful implementation of the low-carbonization strategy is heavily reliant on the development of low-loss and high-efficiency green antenna technology. However, long-term exposure to high heat and oxygen leads to the degradation of antenna materials and the release of harmful substances. Studies on the aging behavior and mechanism of the antenna materials are of essence to realize the low-carbonization strategy. To address this issue, an unplasticized polyvinyl chloride filled with calcium carbonate (uPVC/CaCO3) has been successfully prepared using the injection molding technique. After that, the aging behavior, mechanism, and working lifetime were comprehensively explored under thermal and oxidative conditions. It is found that the composite maintains a high level of functionality for up to 24 years at 60 ℃ and 4.5 years at 70 ℃ on the impact strength failure criterion. The simultaneous oxidation and dehydrochlorination reaction, cross-linking reaction, and deterioration of the interaction between components are responsible for the aging of the uPVC/CaCO3 composite. These findings provide valuable insights into the development of radome materials for achieving low-loss and high-efficiency green antenna technology.

Intrinsic relationship of outdoor activities between climate change and coastal management: Fresh evidence from the spatial analysis of China

By utilizing the mediation effect model and the spatial Durbin model, this research investigates the influence that environmental restrictions have had on marine pollution in 38 coastal prefecture-level cities from the years 2000–2018. In order to gain a comprehensive understanding of the effect that environmental legislation has on contamination in offshore regions as well as its primary goal, the research takes a variety of different approaches into consideration. Following are the findings from the study; Firstly, pollution levels in coastal marine areas tend to rise at first and then fall when environmental laws are enacted, illustrating a non-linear pattern known as an inverted “U" shape. In order to improve the maritime environment through environmental legislation, it is crucial to support new green technologies. There is a “U" shaped linkage amongst environmental legislation and development of environmentally friendly technologies. Spatial spillover effects may allow for the regulation of coastal city environments to affect marine pollution in neighboring areas. Secondly, there is also an inverted “U" pattern visible in the impact trajectory of this effect. According to the results of this research, it is crucial to set up a strict and factually sound regulatory framework in the field of marine environmental governance. It is also suggested that local context be taken into account while crafting environmental regulating regulations. Also, it's crucial to promote development, dissemination, and use of green technology by completely capitalizing on the innovation's conduction effect. Thirdly, promoting cooperation efforts among areas to avoid and control such pollution is essential, and the transfer and management of offshore pollution between regions must be a top priority.

Effect on the oxidation characteristic at lignite of two types of endogenous microorganisms from coal

In recent years, coal biotechnology has gained considerable popularity due to its economic, eco-friendly, and sustainable advantages, which offer a novel perspective and pathway for the development of green technologies aimed at preventing and controlling coal spontaneous combustion (CSC). Two endogenous microorganisms from lignite were succeeded in extracting in this work, namely Aspergillus and Bacillus velezensis. Subsequently, the effect of these microorganisms on the microscopic structure and macroscopic oxidation characteristics of coal was investigated by X-ray diffraction, Fourier-transform infrared spectroscopy, and thermogravimetric analysis. The results revealed that both Aspergillus and Bacillus velezensis treatments altered the microcrystalline structure of the coal, disrupting the aliphatic hydrocarbon structure and oxygen-containing functional groups of the coal molecules. Particularly, the OH − O hydrogen bond of two kinds of microbial treatment coal samples content respectively decreased significantly by 17.29 % and 11.06 % compared to the raw coal sample. However, the effects of different microorganisms on coal varied. Thermodynamic behavior demonstrated that the critical temperature of the two treated coal samples was delayed by 29.44 °C and 26.62 °C, and the ignition temperature was delayed by 11.31 °C and 5.18 °C. Overall, all characteristic temperature points of the Aspergillus group were delayed, but the maximum weight loss rate temperature and the burn-out temperature of the Bacillus velezensis group exhibited slight advancement. The thermal mass loss characteristics also changed during the oxidation combustion stage. In addition, the average activation energies of oxidized combustion stage calculated by the Kissinger-Akahira-Sunose method were 74.26 kJ/mol and 78.61 kJ/mol, respectively, and 82.41 kJ/mol and 86.15 kJ/mol for the Friedman method, which were both increased compared to the raw coal. The results indicate that both Aspergillus and Bacillus velezensis have effects with varying degrees on the coal oxidation characteristics. It can be observed that the effect of treatment with Aspergillus is better than Bacillus velezensis from the overall changes in characteristic temperature points. This work lays the foundation for investigating the effect of microbial action on the oxidative properties of CSC.

Physical Separations for Rare-Earth Beneficiation of the Nechalacho Deposit

The rare-earth elements (REEs) are strategic metals which are indispensable to the development of modern defence systems, electronic applications, and green technologies. The growing economic and strategic importance of these sectors, coupled with uncertainty in the global supply, has led to the development of many new deposits around the world. Many of these deposits, such as the Nechalacho deposit, are complex and contain multiple rare-earth element-bearing minerals (REMs) for which there is limited processing knowledge. This study explores a physical-separations-based flowsheet to beneficiate the Nechalacho deposit, which employs a spiral concentrator to preconcentrate the ore at a relatively coarse particle size (d80 = 120 μm), before further size reduction (d100 = 53 μm) and separation using a Mozley laboratory shaking table and two stages (low- and high-intensity) of magnetic separation. QEMSCAN was used to understand the effectiveness of each stage of separation and provide recommendations to improve the process. Although optimisation would be required, the results demonstrate that the physical-separations-based flowsheet could be an effective method of beneficiation.

Sechs Ansatzpunkte für eine nachhaltige und sozialverträgliche grüne Transformation

Abstract Germany wants to achieve carbon neutrality by 2045, which requires a substantial acceleration in emission reduction. The OECD suggests six levers for a successful sustainability transformation. More comprehensive and coherent greenhouse gas pricing, involving a phase out of environmentally harmful subsidies would set better incentives to switch consumption, production and innovation to climate­friendlier products and technologies. Direct revenue refunds to households would avoid overburdening lower­income groups. Furthermore, there are a number of costly and poorly targeted subsidies for the deployment of renewables that can be reduced gradually. This would make room to offer more support for expediting development of green energy technologies and infrastructure. Workers in energy­intensive industries will need support to retrain and potentially move to other industries or places.

State of Perception and Knowledge of Bioeconomy in Selected European Universities

Abstract Sustainable bioeconomy is one of the concepts that makes it possible to achieve the European Green Deal. A similar understanding of the term bioeconomy gives the opportunity to simultaneously take proportionate actions leading to the implementation of the Sustainable Development Goals in EU countries. Parallel understanding of the concept of bioeconomy is crucial for achieving a common consensus on actions aimed at introducing optimal plans for the development of green technologies. Therefore, the goal of the paper was to compare knowledge and perception about the bioeconomy in different countries. Realization of the work's objective was possible thanks to the use of the C&RT classification tree method. It was shown that the level of knowledge of respondents working or studying at selected universities was similar, while their perception of the bioeconomy differed significantly.

Effects of light quality on microalgae cultivation: bibliometric analysis, mini-review, and regulation approaches.

The ever-increasing concern for energy shortages and greenhouse effect has triggered the development of sustainable green technologies. Microalgae have received more attention due to the characteristics of biofuel production and CO2 fixation. From the perspective of autotrophic growth, the optimization of light quality has the potential to promote biomass production and bio-component accumulation in microalgae at low cost. In this study, bibliometric analysis was used to describe the basic features, identify the hotspots, and predict future trends of the research related to the light quality on microalgae cultivation. In addition, a mini-review referring to regulation methods of light quality was provided to optimize the framework of research. Results demonstrated that China has the greatest interest in this area. The destination of most research was to obtain biofuels and high-value-added products. Both blue and red lights were identified as the crucial spectrums for microalgae cultivation. However, sunlight is the most affordable light resource, which could not be fully utilized by microalgae through the photosynthetic process. Hence, some regulation approaches (e.g., dyes, plasmonic scattering, and carbon-based quantum dots) are proposed to increase the proportion of beneficial spectrum for enhancement of photosynthetic efficiency. In summary, this review introduces state-of-the-art research and provides theoretical guidance for light quality optimization in microalgae cultivation to obtain more benefits.

Robust reactive oxygen species production in interfacial reaction between organic acids and biochar: The combined effect of electron acceptance and electron conduction

Interfacial electron transport and reactive oxygen species (ROS) generation in the redox action between biochar (BC) and low-molecular-weight organic acids (LMWOAs) have been overlooked during the utilization of BC in soil amelioration/remediation. Herein, BC and N-doped BC (NBC) with various physicochemical properties were prepared at pyrolysis temperatures of 350, 550 and 750 °C (namely BC/NBC350, 550 and 750) and their interactions with LMWOAs were systematically investigated. Results of ROS quenching and electrochemical cell experiments revealed that BC/NBC could strongly interact with LMWOAs, especially ascorbic acid (AA), and acted as an electron shuttle to mediate one electron transfer from AA to oxygen to generate O2•−, followed by the robust generation of H2O2 and •OH. Interestingly, the generation rates of •OH and H2O2 in the NBC-AA system were significantly higher than that in the BC-AA system, of which the NBC550-AA system exhibited the best performance, enabling its superior ability in bisphenol A degradation. Different from conventional wisdom, the electron shuttle capacity depended on a combined aromatization degree and electron-accepting capacity of BC/NBC. These findings complement the interfacial electron transfer mechanism during the natural BC-LMWOAs interaction and provide new inspiration for the development of green and efficient organic pollutant removal technologies.

Sustainable Aspects of Startups among Generation Z—Motivations and Uncertainties among Students in Higher Educations

While technology is developing rapidly, natural resources are being exploited with more and more factories. Global environmental problems draw attention to the issue of sustainability as a warning sign. In this situation, encouraging the development of green innovative technologies and supporting green startups has become particularly important. Sustainable development is an important goal for every country, and it means a global competitive advantage if the given country supports the spread of green technologies. It is therefore the responsibility of leading politicians to create an enabling economic environment to encourage young people to become conscious, green-minded entrepreneurs. In this study, we delve into the driving factors compelling young individuals to venture into entrepreneurship. This exploration combines both quantitative and qualitative research methods. A cohort of 280 Hungarian university students participated in an online questionnaire survey as part of the quantitative segment, while the qualitative research component involved scrutinizing young people’s perspectives on enterprises and startups through focus group discussions. The research aims to unveil the motivations and primary concerns of Z-generation university students when contemplating entrepreneurship, as well as their perspectives on the significance of sustainability in this context. The outcomes of this study could serve as a catalyst for the establishment of more environmentally-conscious and sustainable businesses and startups.

Progress in Green and Low-carbon Technologies development of Building Ceramics Industry

As global and domestic concerns about climate change intensify, the development and adoption of green and low-carbon manufacturing technologies to effectively reduce resource consumption, energy usage, and greenhouse gas emissions have emerged as primary trends in the evolution of the building ceramics industry under the backdrop of the “dual carbon” strategy. This article systematically reviews the commercially applied and research-stage green and low-carbon technologies within the current building ceramics industry. It conducts a carbon emission reduction potential analysis for various technologies, identifies constraints in the technology promotion process, and highlights the substantial carbon reduction potential of clean energy substitution technologies and manufacturing process optimization technologies. Technologies such as raw material substitution, high-quality service, and waste ceramic tile recycling and regeneration contribute significantly to economic and environmental benefits, but are still in developmental stages. The article also discusses the application of methods such as life cycle assessment and carbon footprint analysis in the evaluation of green and low-carbon technologies in the field of building ceramics. It discusses the trends and limiting factors of different green and low-carbon technologies, offering suggestions and support for the building ceramics industry’s transition towards a low-carbon and environmentally friendly direction.

Separation Performance of Lithium and Calcium from Synthetic Geothermal Brine Using Electric Field-assisted Membrane

Green low-carbon technology development has spurred an increased demand for lithium. Brine, including geothermal brine, is the world’s largest source of lithium. However, the low lithium content and the presence of other ions pose challenges in concentrating lithium. An electric field-assisted membrane is a separation approach combining nanofiltration membranes with an electric field as an additional driving force, effectively separating lithium from magnesium and strontium. This study was conducted to separate lithium and calcium from synthetic geothermal brine using an electric field-assisted membrane. The separation process is conducted for lithium (50 ppm) and calcium (300, 800, and 2,000 ppm) with variations in electrical voltage (0V, 2V, and 3V). The decrease in lithium rejection reaches up to 50% at an electrical voltage of 2V. Conversely, the increase in electrical voltage does not significantly impact calcium rejection (calcium rejection remains at 89% with an electrical voltage of 3V) and the permeate flux for lithium and calcium. The increasing calcium concentration affects permeate flux significantly but does not notably affect calcium rejection, with the rejection remaining above 85%. The findings suggest the feasibility of concentrating lithium through electric field application without compromising calcium rejection within a single salt solution system.

Power allocation strategy for fuel cell distributed drive electric tractor based on adaptive multi-resolution analysis theory

Fuel cell distributed drive electric tractor (FCDET) provided a novel pathway for the development of green agricultural machinery technology. However, FCDET faced problems such as low traction efficiency, short endurance, and high hydrogen consumption. Relevant studies have shown that reasonable and effective power allocation strategy can improve the efficiency and reduce the energy consumption of fuel cell systems. In this paper, a drive power allocation strategy based on adaptive multi-resolution analysis theory (AMRA) was proposed. The strategy could realize effective decoupling between various energy sources, reduce the problems of frequent start-stop and large power fluctuation for fuel cells. We started with an equivalent circuit model of the fuel cell system, a total efficiency solution model, an energy dissipation model, and a drive motor response model. The first-time reconstruction strategy was based on Tunable Q-factor Wavelet Transform (TQWT) to obtain a subsequence that responds to the oscillatory characteristics of the power signal. The second-time reconstruction strategy took the low-frequency subsequence through Variational Mode Decomposition (VMD) into a number of discrete sub-signals with special sparse properties. Meanwhile, the Sparrow Search Algorithm (SSA) was used to obtain the optimal combined values of the modal decomposition layers and the quadratic penalty factor in the VMD on real time. Finally, the second-time decomposed subsequences and sub-signals were reconstructed according to the frequency characteristics, and the reconstructed power signals were redistributed among the individual energy sources. In order to validate the proposed power allocation strategy, we used the ET504-H prototype as a research object. The power information of plowing and transportation operating conditions was collected in Mengjin test base of China YTO Group. The MATLAB/Simulink-PXI joint simulation platform was set up and the driving motor bench test was carried out in the New Energy Key Laboratory of Henan Province. The results show that the AMRA-based FCDET drive power allocation strategy can effectively improve the energy utilization of the fuel cell system and the economy of the whole tractor operating unit. Compared to the power-following strategy under plowing and transportation conditions, the average efficiency of the fuel cell system was improved by 8.3 % and 3.3 %, the equivalent hydrogen consumption was reduced by 35.6 % and 43.89 %, respectively. The average efficiency of the drive motor was improved by 2.06 % and 2.08 %, the total energy consumption was reduced by 3.73 % and 2.6 %, respectively. This study can provide a theoretical foundation and a novel technical approach for the development of FCDET control system.
