Summary: Polymer molecules, mainly found in plastics, are pollutants in different environmental compartments and can have ecotoxicological effects on organisms. Understanding the interaction between plastic particles and bacterial cell membranes is important for assessing their risks in ecosystems and human microbiota. This study investigates the interaction between 100 nm polystyrene nanoparticles (PS NPs) and two types of bacteria, Staphylococcus aureus and Klebsiella pneumoniae. The nanoparticles attach to the bacterial cell membranes, altering their charge, but without killing the cells. The zeta potential values of the bacteria change depending on the particle concentration, pH, and exposure time.

Summary: Research on the roughness parameters of the layered interface of the layered cemented tailings backfill is important for the safety and stability of mine structures. The study found that the existence of stratified surfaces significantly decreases the cementation quality, but increasing the solid density can reduce the strength reduction caused by layering. Additionally, a larger surface roughness of the stratified plane results in better cementation quality.

Summary: The study investigated the relationship between water holding and gel properties of protein-based hydrogels, focusing on ovalbumin-carboxymethylcellulose electrostatic complexes. It was found that the degree of substitution of carboxymethylcellulose affected the gel network structure and properties, while the addition of salt ions enhanced gel strength but decreased water holding capacity with increasing ionic strength.

Summary: In this study, continuous dangling bond (DB) wire structures patterned on hydrogen terminated silicon surfaces were examined using a non-contact atomic force microscope (nc-AFM). By probing the DB structures at varying energies, previously unobserved ionic charge distributions were identified, correlated to the net charge of the DB wires and their predicted degrees of freedom in lattice distortions. Spectroscopic analysis revealed higher energy configurations corresponding to alternative lattice distortions and tip-induced charging effects.

Summary: The present study investigated the tribological behavior of PTFE composites filled with natural layered silicates. It was found that the content and chemical composition of layered silicates affect the morphology of the friction surface of the composites. The formation of a special layer on the friction surface, independent of the silicate content, was observed, indicating the formation of a protective layer during friction.

Summary: Organic materials can modify the optical properties of layered (2D) hybrid perovskites, and their effects on photophysics are often overlooked. In this study, the impact of spacer size and perovskite phase configuration on charge transfer excitons in 2D perovskites is investigated using transient absorption spectroscopy and electroabsorption spectroscopy. It is found that charge transfer excitons form in the Dion-Jacobson (DJ) phase, leading to a photoinduced Stark effect dependent on the spacer size. Moreover, temperature-dependent measurements reveal new features in the transient spectra of the Ruddlesden-Popper (RP) phase at low temperatures due to the quantum-confined Stark effect.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
