Summary: Antibody adsorption to NanoAct (R) nanoparticles is thermodynamically influenced, with greater adsorption and color intensity observed as pH decreases. Changes in net charge of the antibody surface as a function of pH impact the pH dependence of adsorption process. Increased positive charge on the antibody surface leads to a more sensitive NanoAct (R)-based immunoassay.

Summary: The need for economical catalysts for combustion reactions drives continuous catalyst development. Differential Thermal Analysis (DTA) and Differential Scanning Calorimetry (DSC) are presented as suitable techniques for fast evaluation of catalyst activity. The heat of reaction Delta H-r generated at the catalyst is used as a measure for estimating the capability of the catalyst. These investigations demonstrate the reliability of DTA and DSC for pre-selecting catalysts for further research.

Summary: The contribution of thermodynamics of mixing to glass transition in polymer-modified asphalt binders was studied quantitatively using a differential scanning calorimeter with an epoxy system. The miscibility of the binders was determined by measuring the heat capacity (Cp) and glass transition temperature (Tg) based on entropic changes. The enthalpy of mixing was also examined to ensure complete crosslinking of the binders. The results showed that the positive deviations of Tg from the ideal mixing rule indicated the presence of repulsive forces between the asphalt and epoxy components.

Summary: The co-occurrence of nanoplastics with metal oxide nanoparticles and polycyclic aromatic hydrocarbons has been widely studied, yet little is known about their interactions and combined toxic effects. This research found that increasing the concentration of metal oxide nanoparticles led to aggregation of nanoplastics, while polycyclic aromatic hydrocarbons had no major impact on nanoplastic stability. The size of the nanoplastics played a role in genotoxicity, with smaller nanoplastics showing higher levels of DNA damage.

Summary: Proteins are diverse biopolymers that participate in almost all processes in living cells. When nanoparticles interact with proteins, they form a protein corona layer, which influences their interactions. The characteristics of nanoparticles such as size, surface chemistry, and charge play a critical role in determining the behavior of the protein corona.

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 study presents a novel heterojunction structure (SrTiO3/CN-TAL10.0) for enhanced photocatalytic water splitting (PWS). The incorporation of thiophenedicarboxaldehyde (TAL) through copolymerization significantly improves the photocatalytic activity of carbon nitride (CN) while maintaining its photostability performance. The optimized composition allows efficient isolation of photoinduced charge carriers and enhanced charge transport, resulting in a remarkable increase in overall photocatalytic efficiency.

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.
