Summary: We have developed a new method for determining ethanol concentration using anti-aggregation of silver nanoparticles (AgNPs) in the presence of melamine. Ethanol acts as a protecting agent, while melamine acts as an aggregating agent. The method demonstrates the ability of ethanol to surround and prevent aggregation of the AgNPs caused by melamine, allowing for accurate determination of ethanol concentration.

Summary: Beta-lactoglobulin can form nano-fibrils with high surface area and hydrophobic properties. The study investigated the effects of ethanol on the surface properties, microscopic interaction forces, secondary structure, and morphology of the fibrils. It was found that ethanol concentration affected the length, diameter, and mechanical properties of the fibrils, as well as the protein-protein interactions and solvent interactions. The surface hydrophobicity of the fibrils increased with ethanol concentration. The impact on interfacial functional properties will be further explored.

Summary: Novel cationic amphiphiles of the MPI-n series were synthesized and their aggregation properties, solubilization capacity, and biological activities were investigated. The MPI-n exhibited lower critical micelle concentrations (CMCs) than their nonfunctionalized counterparts. The amphiphiles with different alkyl chain lengths formed aggregates with distinct morphologies. The MPI-n aggregates showed high solubilization capacity and displayed strong antimicrobial activity with low hemolytic activity.

Summary: The study revealed that mixed systems of DDA and NaOL more easily formed aggregates and exhibited higher surface activity, with stronger interactions in the 1:1 molar ratio mixed system. Electrostatic interactions were found to be the main contributors to improved aggregation in the mixed systems, along with hydrogen bonds between NaOL and DDA. These findings suggest that mixed NaOL/DDA surfactants have great potential in mineral flotation applications.

Summary: The absence of a versatile, scalable, and defect-free bottom-up assembly of nanoparticles has been a challenge for the large-scale integration of nanoparticle-based devices. In this study, we propose a self-limiting dielectrophoretic approach that can precisely align nanoparticles onto electrodes over a large area. Experimental results show a 70% yield of single-nanowire assembly, and factors limiting the current yield are discussed. Improving nanoparticle-electrode contact and reducing capillary force during the drying process are expected to further increase the yield. The approach also demonstrates versatility for scalable and site-selective alignment of various nanoparticles.

Summary: Utilizing the IR-thermal effect to facilitate sluggish electrocatalytic reactions is a promising way to utilize the IR band of the solar spectrum. In this study, NF/NiCo2O4 NNs were prepared as both the IR absorbing antennae and the OER active anode to promote the oxygen evolution reaction via the IR-thermal effect. The enhancement of OER activity is attributed to the localized temperature rise under IR irradiation, which reduces the kinetic energy barrier of the OER and facilitates OER kinetics.

Summary: This study proposes a sensitive and convenient method for quantitatively detecting anodically produced hypochlorite ions (ClO-) during alkaline seawater splitting. The method involves online sample collection and offline UV-vis analysis using a starch-iodide solution to capture ClO-. The method exhibits a strong anti-interference ability and a detection limit of 5μM in both simulated and real seawater. The study also demonstrates the potential- and time-dependent production of ClO- during anodic OER, and calculates the Faradaic efficiency of OER and ClER. The detection method shows precision and reliability, with a total Faradaic efficiency close to 100%. Overall, this work is important as it provides a valuable method for monitoring ClER during alkaline seawater splitting.

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.
