Summary: This work investigates the permselectivity and transport properties of an ionene-based anion exchange membrane, finding that thicker membranes exhibit higher permselectivity and fixed charge group concentration, leading to better performance. The permselectivity and specific area conductivity of Aemion AEMs were determined by their fixed charge group concentration, with the AF1-HNN5-50 membrane showing comparable performance to the common anion exchange membrane Selemion AMV.

Summary: This study proposes a novel method to enhance the signal-to-noise ratio of electrical signals of single particles using optical tweezers and a microchannel. By trapping a microparticle in a micro-orifice, the electrical signal from a target particle passing by can be sharpened and separated from background noise. By switching the micro-orifice between opening and closing with near-infrared light, target particles can be transported to the sensing section effectively.

Summary: The introduction of oxygen vacancies carried by nanosized Al2O3 fillers promotes Li+-conduction in poly(ethylene oxide) by weakening the Coulombic attraction within ion pairs and preferentially constraining the movement of anions, leading to significant and selective improvement in Li-ion conductivity. Solid state batteries built on such PEO-based electrolytes exhibit superior performance at high current density, offering a universal approach to tailor superior polymer-based electrolytes for next generation solid-state batteries.

Summary: In this study, a facile and environmentally friendly surface roughening method was used to create (super)hydrophobic aluminium surfaces. The durability, corrosion resistance, and self-cleaning/anti-icing abilities of the grafted surfaces were evaluated. The results showed that the grafted aluminium surfaces exhibited highly hydrophobic or superhydrophobic behavior, with the perfluorooctyl silane showing greater durability and stability compared to the octyl silane. The aluminium surface etched for 2 minutes and grafted with perfluorooctyl silane demonstrated excellent self-cleaning and anti-icing performance.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

Summary: This study aims to develop a nano-biofungicide comprising of volatile essential oil molecules to enhance its efficacy in the field of agriculture through easily scalable green synthesis technique. The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
