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. Photocatalytic hydrogen production tests reveal a favorable hydrogen evolution rate of 20.9 μmol h−1 g−1 with 0.45 M FeCl2 doping, attributed to improved surface structure and crystallinity of the hydrotalcite.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 4","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.202400309","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770565","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, 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}

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.

Despite significant advancements in catalyst development, no single material meets the requirements for mobile applications. This limitation is primarily due to the suboptimal performance of catalysts in terms of hydrogen production efficiency and stability. To enhance the catalytic performance of sodium borohydride hydrolysis, a boron oxide-coated Co–Pt/boron nitride (BN) nanocomposite material has been developed, leveraging the oxidative support–metal strong interaction. The results demonstrate that CO2 oxidation etching of the BN facilitates the migration of boron oxide to the Co–Pt nanoparticles, forming a structurally robust coating layer. This configuration exhibits a strong synergistic effect between Co and Pt, significantly enhancing catalytic hydrogen production efficiency. Furthermore, the boron oxide overlayer effectively stabilizes the catalyst structure by preventing metal component loss and the deposition of sodium borate on the metal surface. The surface BOx also modulates the electronic properties of the bimetallic active sites. Ultimately, the optimal 0.4%Pt–5%Co/BN catalyst achieves a high hydrogen generation rate of 8272 mL·min−1·gmetal−1 and turnover frequency of 668 min−1 at room temperature while retaining 90.1% of its initial intrinsic activity after ten cycles.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 6","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.202400313","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256302","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}

Herein, the 2PACz, a typical SAM with the largest dipole moment, is chosen as the model system and is studied by vacuum deposition. It is found that the energy level alignment is determined by the orientation of 2PACz molecules on a different substrate. The molecules are lying down on highly oriented pyrolytic graphite and giving nearly zero interface dipole. On solvent-cleaned and plasma-treated indium tin oxide (ITO) substrates, the SAM is vertically assembled with 0.22 and 0.13 eV work function increases, respectively. However, on sputtered ITO, SAM is assembled with upside down orientation, with 0.51 eV work function decrease. The change of orientation is due to strong interaction between oxygen vacancies in ITO substrate and carbazole head group of 2PACz. On perovskite film, SAM also shows a slightly upward orientation with additional passivation of free MA+ ions.
