Multifunctional microwave absorption materials: construction strategies and functional applications.

The widespread adoption of wireless communication technology, especially with the introduction of artificial intelligence and the Internet of Things, has greatly improved our quality of life. However, this progress has led to increased electromagnetic (EM) interference and pollution issues. The development of advanced microwave absorbing materials (MAMs) is one of the most feasible solutions to solve these problems, and has therefore received widespread attention. However, MAMs still face many limitations in practical applications and are not yet widely used. This paper presents a comprehensive review of the current status and future prospects of MAMs, and identifies the various challenges from practical application scenarios. Furthermore, strategies and principles for the construction of multifunctional MAMs are discussed in order to address the possible problems that are faced. This article also presents the potential applications of MAMs in other fields including environmental science, energy conversion, and medicine. Finally, an analysis of the potential outcomes and future challenges of multifunctional MAMs are presented.

Carbon Emission Analysis of RC Core Wall-Steel Frame Structures

The development of super high-rise building projects has become crucial for mitigating land shortages in rapidly growing urban areas. Super high-rise steel structures, particularly RC core wall-steel frame systems, have become the preferred choice due to their superior performance, high prefabrication level, and construction efficiency. Despite their benefits, super high-rise buildings face challenges related to higher energy consumption and carbon emissions. Consequently, it is important to analyze the carbon emissions of these buildings throughout their lifecycle and propose low-carbon construction strategies. A carbon emission analysis focused on super high-rise buildings with RC core wall-steel frame structures is conducted in this study. A carbon emission analysis model is constructed based on BIM-enabled LCA through a real-world case study. The emission factor method is combined with the BIM model to calculate carbon emission. Furthermore, carbon emissions across various construction strategies are compared, with a particular focus on the manufacturing processes of the main materials. The results indicate that incorporating admixtures in concrete, along with adopting the electric arc furnace (EAF) method and utilizing recycled scrap steel in steel manufacturing, significantly reduces the carbon emissions of the buildings. Lastly, effective low-carbon approaches for these buildings are proposed.

P-CoFe2O4/CNTs as efficient bifunctional electrocatalyst for water splitting

The process of electrocatalytic water splitting is a promising technology for the generation of green hydrogen, despite challenges such as low electrical conductivity and limited activity in the application of the CoFe2O4 catalyst. This study presents the development of a novel bifunctional P-CoFe2O4/CNTs catalyst with enhanced catalytic performance through the combination of heterojunction construction and heteroatom doping strategies. The enhanced electrical conductivity and increased active sites of P-CoFe2O4/CNTs, resulting from the synergistic effect of the unique heterojunction structure and oxygen vacancies induced by P-doping, lead to exceptional hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) performances in acidic and alkaline environments, respectively. The catalyst design presented in this study has the potential to inspire the development of novel bifunctional catalysts with superior catalytic activity.

Agreeableness and Conflict Management in Daily Life: The Impact of Prosocial Traits on Psychological Adaptation

This paper explores the role of agreeableness, a key personality trait characterized by prosocial behaviors such as empathy, altruism, and cooperation, in conflict management and psychological adaptation in daily life. Agreeable individuals, driven by a focus on harmony and understanding, tend to employ constructive conflict resolution strategies that prioritize relational well-being and mutual respect. These strategies reduce interpersonal tensions, promote trust, and enhance relational satisfaction. Furthermore, agreeableness contributes significantly to psychological adaptation by fostering positive social interactions, enhancing emotional regulation, and promoting adaptive coping mechanisms, which together support resilience in the face of life’s challenges. The broader implications of agreeableness extend beyond individual relationships, influencing organizational dynamics, community engagement, and societal harmony by reducing conflict, fostering inclusivity, and bridging ideological divides. This paper highlights the importance of agreeableness in shaping both personal well-being and social cohesion, emphasizing its role in promoting a more empathetic, cooperative, and resilient society.

Addressing the Housing Shortage Gap in Nigeria: An exploration of Dry Construction Method

Due to Nigeria's housing shortage, which has been increasing since the late 20th century and currently stands at 20 million units with a loss rate of 780,000 units annually, Nigeria's construction industry has been under pressure to adopt a modern, timely, and premium construction strategy. This research aims to assess how the dry construction method affects mass housing delivery in developing countries, focusing on Nigeria. This study employed a qualitative research approach, conducting semi-structured interviews with sixteen experts and specialists in dry construction and housing who work for various organisations in Nigeria. The study concluded that, although dry construction is infrequently used in developing countries, it offers significant potential for emerging economies and mortgage companies to ensure prompt housing delivery. By reducing building time and improving housing accessibility, dry construction can address the current challenges of delivering affordable housing in Nigeria. To successfully implement the dry construction method in closing the housing deficit in Nigeria, the research also noted that the government must change its priority beyond direct house development towards creating a conducive framework for the industry. This study presents key stakeholders in the housing sector with the information they need to adopt and implement the dry construction method to close the housing gap, especially in Nigeria, which has received less attention.

Mesoporous Hollow Carbon Sphere-Embedded MXene Architectures Decorated with Ultrafine Rh Nanocrystals toward Methanol Electrooxidation.

The development of advanced Pt-alternative anode electrocatalysts with high activity and reliable stability is critical to overcoming the technical challenges of direct methanol fuel cells. Here, we propose a robust bottom-up strategy for the spatial construction of mesoporous hollow carbon sphere (HCS)-embedded MXene architectures decorated with ultrafine Rh nanocrystals (Rh/HCS-MX) via stereoscopic coassembly reactions. The rational intercalation of HCS effectively separates the MXene nanowalls to achieve a rapid mass-transfer efficiency, while the intimate coupling of the hybrid carrier with Rh nanocrystals enables their electronic structure optimization, thus contributing to strong synergistic catalytic effects. Accordingly, the resulting Rh/HCS-MX architectures exhibit outstanding methanol electrooxidation properties in terms of large electrochemical active surface areas, high mass/specific activities, and good long-term stability, all of which are significantly superior to the traditional Rh/carbon black, Rh/HCS, and Rh/MXene as well as commercial Pt/carbon balck and Pd/carbon balck electrocatalysts.

Analysis of the Choice of Cement in Construction and Its Impact on Comfort in Togo

The cement industry, a key player in globalization and urbanization, has replaced traditional shelters with modern buildings, raising environmental concerns. This study examines the use of cement in construction in Togo, its impact on residents’ thermal comfort, and adaptation strategies for sustainable construction and well-being. The research was conducted in Lomé, Atakpamé, and Kara through documentary research, photography, household surveys, interviews, and temperature recordings, involving 646 households and nine interviews. Findings reveal a high use of cement due to availability, ease of use, strength, affordability, and aesthetics. Cement houses are generally less comfortable than earthen houses, particularly in hot climates. Lomé and Kara experience higher discomfort, while Atakpamé has lower discomfort despite cement dominance. Thermal comfort varies more during the day. Residents adopt strategies like sleeping outside, wearing light clothing, installing awnings and false ceilings, planting trees, staying hydrated, taking cool showers, and ventilating rooms.

Efficient adsorption of hydroxychloroquine by carboxylated lignin-based sponge: Quantification of the adsorption contribution of interactions

Hydroxychloroquine (HCQ) as an antiviral pharmaceutical has been widely detected in the aquatic environment. Adsorption is an effective method for removal of HCQ, but the quantitative study of the adsorption interactions is unclear. In this study, a carboxylated lignin-based sponge (PLC) was fabricated, and the adsorption contributions of electrostatic attraction (EA), hydrogen bond (HB), and π-π electron donor–acceptor (π-π EDA) interactions were quantitatively investigated. The results showed that PLC exhibited excellent adsorption performance under wide pH range (4.0 < pH < 11.0), with the highest adsorption capacity of 0.165 mmol/g. Inhibitor and molecular probe experiments showed that EA and HB were the main contributors to adsorption at neutral and basic pH ranges, respectively. A linear correlation model of the carboxyl groups of lignin-based sponges with the adsorption capacity of EA, HB, and π-π EDA interactions of HCQ (R2 > 0.822) and three molecular probes (R2 > 0.749) was established, respectively. The optimal adsorption capacity was achieved by the synergistic combination of the deprotonated carboxyl of PLC with the HB of Ka1 amino, EA of Ka2 amino, and the π-π EDA of the quinoline ring. This study provided a new strategy for the quantitative construction of structure–activity relationships of adsorbents.

Construction of Knowledge Graphs: Current State and Challenges

With Knowledge Graphs (KGs) at the center of numerous applications such as recommender systems and question-answering, the need for generalized pipelines to construct and continuously update such KGs is increasing. While the individual steps that are necessary to create KGs from unstructured sources (e.g., text) and structured data sources (e.g., databases) are mostly well researched for their one-shot execution, their adoption for incremental KG updates and the interplay of the individual steps have hardly been investigated in a systematic manner so far. In this work, we first discuss the main graph models for KGs and introduce the major requirements for future KG construction pipelines. Next, we provide an overview of the necessary steps to build high-quality KGs, including cross-cutting topics such as metadata management, ontology development, and quality assurance. We then evaluate the state of the art of KG construction with respect to the introduced requirements for specific popular KGs, as well as some recent tools and strategies for KG construction. Finally, we identify areas in need of further research and improvement.

GSH Oligomer-Directed Chiral Au-Helicoid Nanoparticles for Discriminating Penicillamine Enantiomers.

Preparing chiral plasmonic nanoparticles (NPs) with strong chiroptical responses is crucial in numerous fields including constructing optical materials, chiral sensing, and chiral-dependent biological processes. However, precise regulation over the chiral optical activity and chiral configuration of plasmonic NPs is still a challenge. In this work, we report Au helicoid NPs with different chiral structures and reversal chirality directed by the oligomeric structure of inducer glutathione (GSH). By precisely controlling the oligomeric structure of GSH and other synthetic parameters, we successfully prepared chiral Au helicoid NPs with a high anisotropy factor of 0.03. The obtained chiral Au NPs demonstrated an excellent performance in discriminating penicillamine (Pen) enantiomers. Our findings provide a construction strategy for chiral Au NPs and contribute insight into the regulation effect of chiral inducers on the growth of chiral metal NPs.

Polychromatic electrochromic films via bipolar covalent organic framework design

Because of the ordered and loose structure, covalent organic framework (COF) holds broad promise in the field of electrochromism, but the simple color change limits its application and development. A bipolar and polychromatic COF-GZU1 was successfully designed and prepared in this paper. The structure, electrostatic potential and orbital structure of the COF-GZU1 were predicted and calculated using density functional theory, and the calculation results confirmed the feasibility of bipolar construction strategy. XRD, SEM, BET and GIWAXS further mutually established the successful synthesis of COF-GZU1, which exhibited high specific surface area, crystallinity and porosity. Results from electrochemical impedance spectroscopy, density of states analysis, and ion diffusion coefficient measurements verified that the ordered porous structure facilitates electron conduction and ion mass transfer, leading to a significant improvement in electrochromic performance. Moreover, the COF-GZU1 film displayed excellent electrochromic performance, providing polychromatic switching with a rapid response time (7.8/14.5 s and 1.0/12.6 s for coloring/bleaching process) and high coloring efficiency (112.8 and 127.8 cm2∙C-1 at 799 and 570 nm). These results collectively demonstrate the superiority of the COF-GZU1 film and suggest that the bipolar COF design strategy could pave the way for new and high-performance polychromatic electrochromic materials.

The Predictive Power of Religious Coping on Care Burden, Depression, Stress, and Anxiety of Parents of Pediatric Oncology Patients in Turkey.

This study aimed to determine the predictive power of religious coping of parents of children with canceron caregiver burden, depression, anxiety, and stress in Turkey. It was designed as a descriptive and cross-sectional study, utilizing correlational analysis and regression models to explore associations between variables. Data were collected from 164 parents in the pediatric hematology-oncology clinics of a university hospital between November 2023 and March 2024. There was a negative correlation between caregiver burden score and negative and positive religious coping scores. Caregiver burden scores werepositively correlated with depression, anxiety, and stress scores. Results indicated that caregiver burden, education level, employment status, family structure, family income, and age at diagnosis significantly predicted positive religious coping. For negative religious coping, caregiver burden, education level, family structure, and family income were significant predictors. This suggests that religious coping may help reduce caregiver burden, underscoring the importance of promoting constructive coping strategies to support caregivers' well-being.

Resilient city construction efficiency and its influencing factors in China's Chengdu-Chongqing Economic Circle: Considering both construction input and resilience level of the city

The growing expansion of urban centers combined with a deteriorating climatic environment raises the likelihood and severity of urban disasters. Thus, there is an urgent need to accelerate the resilient city construction. Here, we use efficiency theory to structure an assessment indicator system of the resilient city construction efficiency to examine the actual correlation of urban resilience enhancement and urban resource consumption. Specifically, 16 key cities in the Chengdu-Chongqing Economic Circle (CCEC) are investigated using the super-efficient SBM and GTWR models. The findings reveal that the resilient city construction efficiency varies greatly among cities in the region, but most cities have relatively low resilient city construction efficiency, showing high resource consumption and low resilience levels. Also, the lower efficiency of regional resilient city construction is mainly due to the serious ineffectiveness of technical and resource inputs, insufficient outputs of ecological resilience and engineering resilience, and is also greatly influenced by factors such as the economic level and the technological innovation level. Upon this basis, we suggest the development strategies for resilient city construction in CCEC. This study broadens the perspective and scope of urban resilience research, and also provides a realistic reference for accelerating the construction of resilient cities.

Reasonable construction of low migration energy barrier and continuous proton transfer channels via bimetallic MOFs nanofibers (MIL-(Cr Al)–NH2) for its composite proton exchange membrane

Reasonable construction of low migration energy barrier and continuous proton transfer channel is the key to improving the performance of composite proton exchange membranes. In this paper, we prepared a novel bimetallic MOFs (MIL-(Cr Al)–NH2) nanofibers (MCANs) consisting of Cr and Al elements by electro-blown spinning method (EBS) and hydrothermal synthesis, and subsequently introduced them into non-fluorinated sulfonic acid polymer sulfonated polysulfone (SPSF) matrix to obtain composite proton exchange membranes (MCANs@SPSF). Importantly, MCANs successfully constructed relatively long-range continuous unsaturated metal site proton transfer channels provided by the Cr-based MOFs, thereby reducing the proton migration energy barrier in the MCANs@SPSF, which confirmed by the density functional theory (DFT) calculation. In detail, DFT studies indicated that the migration energy barrier between H+ and MCANs was 1.677 eV, while that of single Al-based MOF (MAN) and single Cr-based MOF (MCN) were 1.879 eV and 1.762 eV respectively. The existence of efficient low migration energy barrier and continuous proton transfer channels made the proton conduction efficiency of MCANs@SPSF greatly improved, that was under the condition of 80 °C and 100 % RH, the proton conductivity of MCANs@SPSF reached the maximum value of 0.358 S cm−1 and the power density reached 104 mW cm−2. Moreover, MCANs@SPSF-5 displayed best DMFC durability performance with only 14.65 % voltage loss under 24h test. In addition, due to the acid-base pair interaction between MCANs and SPSF enhanced the interface binding force between the two phases, meanwhile, the pore structure of MOFs also had a certain adsorption effect on methanol, thus reducing the methanol permeability, and the addition of 5 wt% MCANs in SPSF was tested to reduce the methanol permeability to 5.53 × 10-7 cm2 s−1. Overall, this work provided a new strategy for construction of low migration energy barrier and continuous proton transfer channels, which was beneficial for the development of high performance proton exchange membranes.

Arbitrary low-frequency power-splitting strategy in ferrite/piezoelectric magnetoelectric heterostructures: theory and experimental validation

Exploring low-frequency (LF) arbitrary power-splitting technologies to address the independent excitation issues of LF/VLF mechanical antennas (MA) with random distributions is challenging due to unidentified device construction and operation mechanism. In light of this, a device construction strategy for three-port magnetoelectric (ME) arbitrary power splitter in composite of ferrite/piezoelectric heterostructure, as well as theoretical model was developed. To validate the feasibility and effectiveness of the strategy, three size-tailored ME samples with length ratio of split PZT segments in 1:1, 2:1, and 3:2 were modeled, fabricated and comparatively characterized. Experimental results show that the achievable maximum power conversion efficiencies (PE) reach 52%, 71%, and 59% for three tailored ME samples, respectively, and as expected the power-splitting ratios are directly proportional to the square ratio of ME voltage coefficient (MEVC) from each port of the tailored ME samples, which are in coincidence with theory under desired operation stability and favorable experiment repeatability evaluated by uncertainties of 0.25854 V cm−1 Oe−1 and 0.32979 V cm−1 Oe−1 for each port. Therefore, a prediction of evolutionary tendency for arbitrary power splitter realization was expanded in view of our experimental observations, and a great flexibility for device future design and further optimization was also provided. Therefore, the presented LF power-splitting strategy paves the ways for arbitrary power splitter realization and enriches the multi-functional ME power electronics families, as well as enables potential applications for efficient excitations of MAs in high-permeable military underwater and civilian emergency rescue distribution long-wave communication system for practical scenarios of submarine, underground railways, tunnels and collapsed residential buildings.
