Application


  • New Functionalized Di-substituent Imidazolium Ionic Liquids as Superior Faster Absorbents for Carbon Dioxide Gas.: This research highlights the development of novel imidazolium ionic liquids, where ethanolamine plays a crucial role in enhancing their efficiency as fast absorbents for carbon dioxide removal, presenting a potential impactful application in environmental science and engineering (Shawish et al., 2024).

  • Role of ethanolamine utilization and bacterial microcompartment formation in Listeria monocytogenes intracellular infection.: This study explores how Listeria monocytogenes utilizes ethanolamine and forms bacterial microcompartments, offering insights into bacterial pathogenesis and potential targets for antibiotic development (Chatterjee et al., 2024).

  • (13)C-Stable isotope resolved metabolomics uncovers dynamic biochemical landscape of gut microbiome-host organ communications in mice.: Research here utilizes ethanolamine in stable isotope-resolved metabolomics to map the dynamic biochemical interactions between the gut microbiome and host organs, advancing our understanding of microbial contributions to host metabolism (Xiao et al., 2024).

Detection of microbial nucleic acids in body fluids has become the preferred method for rapid diagnosis of many infectious diseases. However, culture-based diagnostics that are time-consuming remain the gold standard approach in certain cases, such as sepsis. New culture-free methods

Characterization of immune responses is currently hampered by the lack of systems enabling quantitative and dynamic phenotypic characterization of individual cells and, in particular, analysis of secreted proteins such as cytokines and antibodies. We recently developed a simple and robust

The involvement of macroautophagy/autophagy proteins in B-cell receptor (BCR) trafficking, although suspected, is not well understood. We show that ATG5 (autophagy related 5) contributes to BCR polarization after stimulation and internalization into LAMP1 (lysosomal-associated membrane protein 1)+ and major histocompatibility

The alkanolamine 2-aminoethanol (NH(2)CH(2)CH(2)OH), otherwise known as monoethanolamine (MEA), is a widely used solvent for carbon capture, yet relatively little is known about its atmospheric chemistry. The hydroxyl radical initiated oxidation of MEA is thought to predominantly form the α-aminoalkyl
