Summary: In this study, the effects of a mixture of cationic surfactants and aromatic alcohols on LPSs purified from Escherichia coli were investigated using ITC, surface tension measurements, and QCM-D. The results showed that the interaction between cationic surfactants and LPSs involved electrostatic binding and hydrophobic interaction, while the interaction between aromatic alcohols and LPSs exhibited negatively synergistic effects. Interestingly, the combination of cationic surfactants and aromatic alcohols made the LPS membrane highly susceptible in the absence of Ca2+ ions.

Summary: A novel method for monitoring mineral content of drinking water using responsive complex emulsions was reported, showing changes in droplet morphology to reflect variations in surfactant effectiveness due to metal cation addition. The study demonstrated that salt concentration and valency can influence the extent of droplet response, with divalent cations resulting in a more pronounced response. This device concept may provide a simple and cost-effective alternative for rapid monitoring of water hardness levels.

Summary: The aim of this study was to develop a rapid and convenient fluorimetric method for analyzing lomefloxacin. The method utilized the complex formation between the drug and aluminum ion to produce a highly fluorescent product. The addition of sodium dodecyl sulfate further enhanced the fluorescence intensity, which was measured at 429 nm after excitation at 332 nm. The relationship between emission intensity and lomefloxacin concentration was linear from 10-130 ng mL-1, with a correlation coefficient of 0.9996. The method demonstrated high accuracy and reliability in quantifying the drug in tablet formulations and real human plasma.

Summary: Solidified natural gas (SNG) technology is an attractive option for natural gas storage and transportation, but the use of sodium dodecyl sulfate (SDS) has negative environmental impact. This study aimed to reduce the usage of SDS by compounding it with environmentally friendly additives. The results showed that alpha CD and beta CD promoted hydrate formation when used with SDS, while HPCD inhibited it. This study provides theoretical support for understanding cyclodextrin and surfactant compounding and suggests an effective way for the application of SNG industry.

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.
