Il y a 4 heures · German utility EnBW this week pledged 1 billion euros ($1.08 billion) to build pipelines to carry clean hydrogen as part of a plan for a nationwide grid that will start commercial operations by 2032.
Il y a 5 jours · A chemical bond is an interaction that holds molecules and compounds together by the sharing or exchanging of electrons. When an atom comes into proximity to another atom and its valence (outer) electrons are attracted to the positive (nuclear) charge of the other atom, a bond between the two atoms can be formed.
Il y a 2 jours · From these results, we found that hydrogen of the carboxyl group of OA ligand and lone pairs of CMMs form hydrogen bonds. OA ligand mixed with PO-T2T showed a strong downfield shift in the peaks ...
Il y a 2 jours · Here, we employ single-droplet vibrational Raman spectroscopy to illuminate the structural redistribution within protein hydration water during the phase separation of neuronal IDPs. Our Raman measurements reveal the changes in the water hydrogen bonding network during homotypic and heterotypic phase separation governed by various molecular ...
Il y a 3 jours · Intramolecular hydrogen bonding in the α geometry boosts electron density at the catalytic center, facilitating a shift of ORR to a 4-electron pathway. Conversely, the β geometry promotes a 2-electron ORR and facilitates electrocatalytic hydrogen evolution through an extensive proton charge assembly; offering a paradigm shift to conventional electrocatalytic principles.
Il y a 4 jours · This attraction, hydrogen bonding, explains many of the properties of water, such as its solvent properties. Although hydrogen bonding is a relatively weak attraction compared to the covalent bonds within the water molecule itself, it is responsible for several of the water's physical properties.
Il y a 5 jours · Benefiting from the abundant dynamic hydrogen bonding network in LHOF-DAT SSEs, fast Li+ ion transport (2.2 × 10–4 S cm–1), a high Li+ transfer number (0.88), and a wide electrochemical window of 5.05 V are achieved.
