These CF-GDEs exhibit notably reduced overpotentials and increased electrochemical stability. By combining three distinct macropore-sized substrates, coated with MnOx and hydrophobized with polytetrafluorethylen, a range of CF-GDEs with distinct porosity gradients is designed. In the results, the pivotal role of substrate layers and their hydrophilic/hydrophobic attributes in steering the formation of the electrolyte thin film are unveiled. Specifically, one CF-GDE shows a reduction by one-third of the ηOER (0.24 V) compared to GDEref at 10 mA cm−2. Noteworthy, this CF-GDE also displays excellent long-term stability without degradation, which is a common issue with carbon-based GDEs due to carbon corrosion. Impressively, the stability measurement conditions the active catalyst sites of the CF-GDE and leads to the formation of NiOx, Ni6MnO8, and NiMn layered double hydroxides. This results in a doubling of the current densities.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 4","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770600","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}

In this work, the relevance of static cells for accelerating the search and helping understand degradation mechanisms is focused on. First an easy-to-make and reliable static cell is validated. A simple but effective approach is proposed to investigate active species in the absence of air, which is based on the use of a cheap lunch box (Ar-box) in contrast to the expensive Ar-filled glove box. The relevance of the proposed strategy is demonstrated by investigating two case studies. The 2,6-dihydroxantraquinone/K4Fe(CN)6 in alkaline is studied with and without Ar-box. The air leakage in the static cell in the Ar-box is neglectable, so an Ar-filled glove box is not needed. Interestingly, the use of Ar-box leads to higher capacity fading (1.3% vs 2.5% day−1) since a very small leakage of air prevents the formation of dimers. In neutral pH, the total absence of air using 1,1-bis[3-sulfonatopropyl]-4,4-bipyridinium/K4Fe(CN)6 static cell in the Ar-box leads to an increase in capacity fading (0.2% day−1) compared to reported values using Ar-filled glove box.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 4","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400318","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770611","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}

Nonroad mobile machines (NRMMs) are a key factor of production in many industrial and transportation systems with high-energy intensity. NRMM cover a wide range of application sectors and operate often in harsh environments. This study presents a literature review for NRMM on agriculture and forestry, mining and earth-moving, construction, and ports. It provides an overview of future energy technology and energy-related business factors for NRMM, considering different geographical areas, various energy sources, energy delivery solutions, and different types of powertrains. The best solutions for the case combinations and projected market environments are derived for several case regions. This study also contains a detailed example of an off-grid mining with renewable energy supply. The analysis of the off-grid mining cases clearly reveals the differences between the Nordic conditions and southern conditions. The importance of the wind power as a source for the renewable energy is emphasized in Nordic conditions, but the solar power can augment it during the summer months. Also, the seasonal storage becomes important in the case of Nordic conditions.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 3","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400257","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554989","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}

Oxidative ionothermal synthesis (OIS) offers a green route for zinc oxide synthesis using ionic liquids. To reduce costs, the OIS method uses recovered zinc-containing mixed metal systems, such as electric arc furnace dust, instead of pure metallic Zn. Understanding the interaction of Zn with impure metals during oxidation is essential. This study employs 1-Butyl-3-methylimidazolium chloride ([BMIM]Cl) as the solvent and Fe-doped metallic Zn, the most common waste-stream metal, as the starting material. This study applies quartz crystal microbalance with dissipation to monitor product formation, and X-ray diffraction and scanning electron microscopy to characterize composition and morphology. Results show that FeCl2 doping accelerates the reaction, transforming simonkolleite to Zn–Fe LDH with tunable morphologies. A reaction mechanism for Zn in [BMIM]Cl with FeCl2 is proposed.

However, the plastification of cellulose nanocrystals (CNC) caused by the transition of HB in the presence of water is still insufficiently understood. In this work, the rigid–soft transition of nanoconfined chains in non-ordered regions of CNC surfaces is quantitively described by comparing their strain behaviors with amorphous cellulose. Moreover, this softening (referred to as the “hydro-glass transition”) with increasing relative humidity (RH) is explored, and a threshold RH value (RHt) is identified to characterize the transition. The phenomenon is attributed to the monolayer to multilayer adsorption and eventually capillary condensation of water molecules in wedged mesopores of the CNC films. This triggers a rapid transition of HB from cellulose–cellulose to cellulose–water type in the vicinity of RHt. The hydro-glass transition is promoted by higher temperatures, for example, RHt at 65 °C decreases to 50%. In addition, the presence of surface groups with lower acid dissociation constant (comparing SO3− and OH/COO− moieties) also accelerates this hydro-glass transition process. Thus, a detailed understanding of the thermodynamic changes in hydrogen-bonded nanoconfined polymer chains in the presence of humidity, with implications for developing nanomaterials with RH-controlled properties, is provided.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 4","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400319","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770595","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, a practical long-life device has not been realized, and theoretical aspects including mechanisms and thermodynamics have not been fully clarified. Here, this study provides a practical device and a thermodynamic theory for a concentration cell-based hygroelectric generator (hygroelectric cell, HEC), which enables high-power and long-term electricity generation by day/night humidity changes. Using a Li1+x+yAlxTi2−xSiyP3−yO12 glass–ceramic solid electrolyte membrane with no water permeability, an ideal HEC without self-discharge is realized. The ideal HEC generates electricity in an outdoor environment for over three months with a maximum power density of 60.4 μW cm−2 and an average power density of 3.0 μW cm−2. The maximum power density in the experimental environment reaches 436 μW cm−2. This is 68 times higher than conventional HECs with polymer-based cation-exchange membranes. The ideal HEC can also drive a wireless sensor for more than four months. Furthermore, a thermodynamic model of the ideal HEC, which enables calculations of the maximum work and maximum efficiency, is derived and the model is verified by experiments. This study provides new insights into both thermodynamic theory and device development aspects of the humidity-based energy harvesting.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 3","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400342","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554970","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}

Indications for hydrofluoric acid (HF) scavenging by TMSP could be found in the gas phase as well as on the electrode surfaces; however, it is observed that the use of TMSP leads to the production of HF, which it eventually scavenges. The investigation of the interphase formation shows that the decomposition products of TMSP are integrated into the interphases of both electrodes. This is accompanied by the formation of trimethylsilane as a decomposition product in the gas phase. TMSP also promotes the two-electron reduction of ethylene carbonate (EC), which is deduced both from an increased amount of ethene in the gas phase and from Li2CO3 on the electrode surface. The electrochemical investigations show that cells with TMSP have a lower interphase resistance after continued cycling. However, only the cells with 1 wt% of TMSP in the electrolyte outperform the TMSP-free reference cells. It is concluded that adding more than 1 wt% of TMSP increases the parasitic reactions of the additive to an extent that it partially counteracts its beneficial effect.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 4","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202400297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770588","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}

The addition of Fe2O3 particles to the evaporators enhances the evaporation rate/efficiency up to 2.36 kg m−2 h−1/88.5%. The higher presence of oxygen vacancies defects in the evaporators made with Fe2O3 improves the absorption of light in the UV-Vis range, which in turn, accelerates the desalination of seawater. Moreover, the performance of the solar evaporators is evaluated in absence of solar light. In this case, upconversion (UC) and downconversion (DC) phosphors are attached to the evaporators and such phosphors are excited with near-infrared (980 nm) or ultraviolet (360 nm) light. Consequently, green light is produced by DC/UC, which is absorbed by the evaporators to be heated and the seawater evaporation is induced. The maximum evaporation rate/efficiency produced by the evaporators is 0.738 kg m−2 h−1/84.9%.
