Summary: The effect of electric fields on metal-dielectric Janus particles inducing boojum defect in thin films of a nematic liquid crystal was studied. It was found that boojum Janus particles can self-propel under an ac electric field, and the direction of their motion can be controlled by changing the field amplitude and frequency. This control over particle motility shows promise for tunable transport and microrobotic applications.

Summary: The temperature-dependent ionic conductivity, dielectric behavior, and thermal, structural, and morphological characteristics of nano-composite polymer electrolyte (NCPE) films were comprehensively studied in this manuscript. NCPE films were prepared by hot-press method from a blend of two polymers, Poly (ethylene oxide) (PEO) and Poly (acrylonitrile) (PAN), complexed with sodium perchlorate (NaClO4) complexing salt and titanium dioxide (TiO2) nanofiller. Electrochemical Impedance Spectroscopy (EIS) was used to investigate electrical and dielectric properties and their correlations. The effect of TiO2 concentration on ionic conductivity and dielectric relaxation was investigated at different temperature ranges. Both the smoother surface and the presence of all essential components were verified by scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDAX), respectively. Thermogravimetric Analysis (TGA) revealed high thermal stability, and Differential Scanning Calorimetry (DSC) and X-ray Diffraction (XRD) confirmed enhanced amorphous phase. The cyclic voltammetry (CV) curve exhibits excellent reversibility and cyclability.

Summary: The study found variations in perceptions and patterns of cuffed/uncuffed endotracheal tube usage among anesthesiologists in India. While cuffed ETTs are preferred by more anesthesiologists in pediatric surgeries, concerns over increased resistance to flow and risk of subglottic injury still deter some from routine use. Monitoring of cuff pressure is not consistently practiced, highlighting areas for improvement in safety protocols.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
