This study is concerned with electrochemical investigation of novel high-performance proton exchange membranes based on bio-functionalized montmorillonite and Nafion. It was found that the incorporation of 2 wt% BMMT into Nafion polyelectrolyte matrix results in significantly improved methanol-air fuel cell efficiency of 30% compared to 14% for Nafion(R)117, and about 23-times higher membrane selectivity.

Flavonoids are a major class of natural polyphenolic compounds with potent antioxidant, anti-inflammatory and anticancer properties. Among them, quercetin and catechin have been widely studied due to their significant health benefits and potent free radical scavenging activity. The efficient extraction and separation of these structurally similar antioxidants remains challenging, necessitating the development of high-performance adsorbents.

Moisture-driven energy generators (MEGs) represent a renewable energy technology, yet challenges such as environmental humidity dependence and transient power generation behavior hinder their practical applications. Herein, a high-performance bilayer MEG is developed by integrating MXene-impregnated paper with a polyacrylamide (PAM) hydrogel to realize environmental tolerance and sustained power generation. Electronegative MXene and paper with 3D porous structure synergistically facilitate selective transport of positive charge, while the hydrogel serves as a water reservoir to provide a moist environment and migratory ions.

Hard carbon has emerged as the most widely studied and commercialized anode material for sodium-ion batteries (SIBs). However, improving the charge transfer kinetics within the plateau potential range of the hard carbon anode is crucial for the development of fast-charging SIBs. In this study, we prepared a novel composite material, ZAPA-1300, by uniformly mixing starch, asphalt, and zinc oxide (ZnO), followed by a two-step treatment process.

To date, Cu(I)-based metal halides with high photoluminescence quantum yields (PLQYs) have primarily focused on their zero-dimensional or one-dimensional structures, significantly reflecting the charge or carrier localization. Designing two-dimensional (2D) hybrid copper(I) halides remains a significant challenge for optoelectronic applications, particularly in simultaneously achieving high PLQY and exceptional structural stability. Here, we report a novel series of 2D hybrid Cu(I) halides, (TDMP)CuX (TDMP = 2,5-dimethylpiperazine and X = Cl, Br), synthesized through simple solution-cooling crystallization methods.

This study presents a novel carbazole derivative functionalized with hydroxy diphosphonic acid groups (HDPACz) as an efficient annealing-free hole transport layer (HTL) through strong bidentate anchoring to indium tin oxide (ITO). Compared to conventional mono-phosphonic acid counterparts, HDPACz demonstrates superior ITO surface coverage and interfacial dipole, effectively modulating the work function of ITO. Theoretical calculations reveal enhanced adsorption energy (-3.
