Base-catalyzed thiol-epoxy reactions: Energetic and kinetic evaluations.

The mechanism of the base-catalyzed thiol-epoxide stage of the thiol-ene/thiol-epoxide curing process was investigated using quantum chemical tools. This study searched for conventional tertiary amines with low to medium basicity as initiators to control reaction rates and tailor industrial applications. Challenges arise from the stronger basicity of initiators, leading to an uncontrollable and short curing application period.

To perform or not to perform fasciotomy? A rare case report.

Subcutaneous emphysema, caused by the presence of air or gas in subcutaneous tissues, can be infectious or noninfectious. A thorough clinical evaluation, including both physical examination and radiological imaging, is required to distinguish benign subcutaneous emphysema from necrotizing soft tissue infections. In this article, we report a 12-year-old female patient with benign subcutaneous emphysema of the upper extremity and highlight the importance of an accurate diagnosis to avoid unnecessary surgical intervention.

Effect of Acanthamoeba Spp. Cell-Free Supernatants on Some Bacterial Pathogens.

The fact that free-living amoebae of the genus Acanthamoeba can live in many different environments causes these protozoa to have different interactions with other microorganisms. Investigation of Acanthamoeba-pathogenic bacteria interaction is important for the discovery of new antibacterial agents that can be used against pathogenic bacteria. In this study, it was aimed to investigate the antibacterial effect of cell-free supernatants obtained from Acanthamoeba against some pathogenic bacteria.

A Novel Fluorescent Chemosensor for Sensitive and Rapid Determination of Pb(II) Ions in Aqueous Environments.

This investigation devised an eco-friendly spectrofluorometric Pb(II) ion measurement approach. To determine Pb(II) ions, a polymeric fluorescence sensor membrane with excellent selectivity has been developed. It contains photoinitiators, functional monomers that can be cured under UV radiation, and cross-linking agents.

Photo-Crosslinked Polyurethane-Containing Gel Polymer Electrolytes via Free-Radical Polymerization Method.

Using a novel technique, crosslinked gel polymer electrolytes (GPEs) designed for lithium-ion battery applications have been created. To form the photo crosslink via free-radical polymerization, a mixture of polyurethane acrylate (PUA), polyurethane methacrylate (PUMA), vinyl phosphonic acid (VPA), and bis[2-(methacryloyloxy)ethyl] phosphate (BMEP) was exposed to ultraviolet (UV) radiation during the fabrication process. The unique crosslinked configuration of the membrane increased its stability and made it suitable for use with liquid electrolytes.
