Aqueous rechargeable zinc batteries, despite advantages like safety and performance, struggle with water-based side reactions such as hydrogen evolution corrosion. Regulating the solvation structure of Zn2+ is essential for stability. Introducing n-hexane, a nonpolar alkane, modifies coordination stabilizes Zn anode-electrolyte interface. The miscibility n-hexane improved through formation an oil-in-water macroemulsion amphiphilic Zn(OTf)2 β-cyclodextrin. Macroemulsion stability highly...
Aqueous rechargeable Zn batteries (AZBs) are considered to be promising next-generation battery systems. However, the growth of dendrites and water-induced side reactions have hindered their practical application, especially with regard long-term cyclability. To address these challenges, we introduce a supramolecular metal-organic framework (SMOF) coating layer using an α-cyclodextrin-based MOF (α-CD-MOF-K) polymeric binder. The plate-like α-CD-MOF-K particles, combined binder create dense...
Biopolymer films based on apple skin powder (ASP) and carboxymethylcellulose (CMC) were developed with the addition of extract (ASE) tartaric acid (TA). ASP/CMC composite prepared by mixing CMC ASP solution using a microfluidization technique to reduce particle size. Then, various concentrations ASE TA incorporated into film as an antioxidant antimicrobial agent, respectively. Fourier transform infrared (FTIR), optical, mechanical, water barrier, solubility properties then evaluated...
In this study, protein-based high-oxygen barrier multilayer films were manufactured at a pilot plant scale by roll-to-roll coating process and an adhesive lamination process. Also, their characteristics examined to evaluate industrial feasibility. Oxygen transmission rates (OTRs) of the (polyethylene terephthalate [PET]/pea protein isolate [PPI]/nylon/cast polypropylene [CPP], PET/whey [WPI]/CPP, PET/WPI/nylon/CPP, PET/PPI/nylon/low-density polyethylene [LDPE]) significantly lower than OTR...
Metal–organic framework, a water-rich additive in the MEA, enhances power performance of PEMFCs at low RH by promoting water back-diffusion.
Abstract Two new polyacylhexaazaisowurtzitanes were synthesized. Pentaacetyl‐ or pentaacetylformylhexaazaisowurtzitane can be a precursor in the preparation of HNIW, recently developed highly energetic material.
Ceroxidnanopartikel können als Radikalfänger für reaktive Sauerstoffspezies wirken. In der Zuschrift auf S. 11201 ff. zeigen S.-H. Lee, T. Hyeon et al., dass einheitliche 3 nm große PEGylierte vor ischämischem Hirninfarkt schützen und das Ausmaß Apoptose verringern können. Optimale Dosen Infarktvolumen verlangsamen den ischämischen Zelltod. Die Nanopartikel wandern in vivo zum Ort des Infarkts.
Aqueous rechargeable zinc-ion batteries (ARZBs) are promising energy storage systems (ESSs) due to lots of advantages, such as high safety, capacity, abundant resources, and low cost. However, the tunnel-structured Mn-based cathode materials α, β, γ-MnO

Regulating the solvation structure of Zn2+ is essential for stability. Introducing n-hexane, a nonpolar alkane, modifies coordination stabilizes Zn anode-electrolyte interface. The miscibility n-hexane improved through micelle formation amphiphilic Zn(OTf)2 β-cyclodextrin. Micelle stability highly sensitive to component...
Owing to high oil prices and environmental issues, the automobile industry has conducted considerable research made large investments manufacture a high-efficiency automobiles. In case of wheels in which lightweight material is used increase fuel efficiency mold production efficiency; however, use molding method for this purpose very expensive. Therefore an wheel consists two parts. study two-piece manufactured by friction stir welding(FSW) Al6061-T6 reduce manufacturing cost process...
Pipe and Pressure Vessels that is used in power plant chemical industry have many Internal Defects corrosion caused by the flow of fluid. These possibility explosion are very dangerous because it can not see from outside. This days companys using NDT method to find an Defect. Most methods limitations constraint shape materials. But Sheargoraphy advantages compared conventional method. It has fast measuring speed, non-destructive non contacting measurement. As well as hasn't a paper on...
