Plasma membranes are known to segregate into liquid disordered and ordered nanoscale phases, the latter being called lipid rafts. The structure, lipid composition, and function of lipid rafts have been the subject of numerous studies using a variety of experimental and computational methods. Double electron-electron resonance (DEER, also known as PELDOR) is a member of the pulsed dipole EPR spectroscopy (PDS) family of techniques, allowing the study of nanoscale distances between spin-labeled molecules.

This study explores Zeolitic Imidazolate Frameworks (ZIFs) as promising materials for adsorbing alcohol vapors, one of the main contributors to air quality deterioration and adverse health effects. Indeed, this sub-class of Metal-Organic Frameworks (MOFs) offers a promising alternative to conventional adsorbents like zeolites and activated carbons for air purification. Specifically, this investigation focuses on ZIF-8_Br, a brominated version of ZIF-8_CH, to evaluate its ability to capture aliphatic alcohols at lower partial pressures.

Corrosion resistance, hardness and other mechanical properties of high entropy alloys are enhanced due to the addition of the proper elements. In this study, an equimolar powder mixture of AlNiCoCrFe was prepared as a coating material on plain carbon steel. It was produced by gas tungsten arc welding with the electrical currents of 90, 110 and 130 A.

The five-coordinate complex [RuCl(PNP)] () was synthesized from the binuclear [RuCl(-cym)] with a PNP-type ligand (PNP = 3,6-di--butyl-1,8-bis(dipropylphosphino)methyl)-9-carbazole - (Cbzdiphos )H) in a toluene solution, within 20 h at 110 °C, producing a green solid, which was precipitated with a 1/1 mixture of - pentane/HMDSO. The complex was characterized by NMR-H, C, and P{H}, mass spectroscopy-LIFDI, FTIR, UV/vis spectroscopy, and cyclic voltammetry, as well as a description of the optimized structure by DFT calculation. The reactivity of was investigated in the presence of potassium triethylborohydride (KBEtH, in THF solution of 1.

Meeting the contemporary demand for the development of functional, biocompatible, and environment friendly self-assembled structures using efficient, cost-effective, and energy-saving methods, the field of colloids has witnessed a surge in interest. Research into cationic and anionic (catanionic) surfactant combinations has gained momentum due to their distinct advantages and synergistic properties in this context. Catanionic self-assemblies have emerged as promising contenders for addressing these requirements.
