Using Pb(Ni_1/3Nb_2/3)O₃-Pb(Zr_0.3Ti_0.7)O₃-LiNbO₃(PNN–PZT–LN) ceramic with a high piezoelectric charge coefficient (<i>e</i>₃₃) and operating in decoupled diagonal symmetric bending modes, this design efficiently harvests omnidirectional stray magnetic energy.

The portable MME-EH generates a record-high output power of 13.3 mW_avg under a weak 2Oe magnetic field at 50 Hz. More importantly, its output power changes less than 22% as the magnetic field direction varies from 0° to 360°, demonstrating omnidirectional energy-capturing capability.

The results indicate that the best electrochemical performance is achieved by balancing the residual water content introduced by NaCMC while maintaining the anode's volume resistivity. A NaCMC with a low molecular weight and DS of 0.7 shows the best results for this particular formulation. An impurity (in batteries yet unreported)in NaCMC is also reported that significantly impacts electrochemical performance, called gel particles. By reducing the gel particles, cell performance is enhanced by 5%, without further optimization of the formulation. It is highlighted that both DS and MW influence electrode properties. A decrease in DS enhances adhesion but negatively affects volume resistivity. Increasing the MW improves adhesive strength and reduces interfacial resistivity due to greater chain entanglements. Higher gel particle levels negatively impact electrode properties, making low-gel NaCMC more effective for better adhesion and resistance. Water retention in electrodes again is influenced by both DS and MW. Higher DS leads to increased water retention due to greater hydrophilicity, while high MW contributes to this effect through enhanced entanglements.</p>","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 6","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400364","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, sustaining this biodecomposition within insect populations presents challenges, as high mortality rates and relatively slow decomposition rates limit the viability of large-scale plastic recycling. To enhance the process, protein-rich nutritional additives are usually necessary. Despite this, there has been little guidance on selecting suitable nutrients for plastic-eating insects like mealworms. In this systematic investigation, aqueous solutions of representative nonessential amino acids (NEAAs) and essential amino acids (EAAs) are used and compared as additives for the biodecomposition of polystyrene by mealworms. The study demonstrates that the essentiality and abundance of amino acids in mealworms significantly impact the rate of plastic biodecomposition. High-abundance EAAs, such as phenylalanine (Phe) and valine (Val), provide the most notable rate enhancements, while low-abundance NEAAs, such as cysteine (Cys), do not enhance the rate. The results also indicate that both water and individual free amino acid solutions effectively reduce cannibalistic behavior among mealworms, while enhancing their nutritional value. These findings provide a more rational basis for selecting cofeeds to improve this biodecomposition process.</p>","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 6","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400378","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are limited study on the environmental performance of this hydrogen evolution process, particularly the potential emission of the photocatalyst synthesis process. In this work, the environmental emission of photocatalytic hydrogen evolution process is investigated through life cycle analysis (LCA) based on a pilot scale reaction system. The individual processing steps with its corresponding material flows that contributed significantly to environmental emission are identified from the LCA simulation. Excessive use of sacrificial reagent in the photocatalysis reaction has been identified as one of the main contributors to the environmental emission of this reaction system.
