that give promise of more precise timekeeping・ In their search for precision, scientists have turned to atomic clocks that depend on various vibrating atoms or molecules to supply their "ticking" .This is possible because each kind of atom or molecule has its own characteristic rate of ...
(a) Compounds of carbon and hydrogen are called hydrocarbons. For example, methane, ethane, etc. (b) Saturated hydrocarbons contain carbon-carbon single bonds. Unsaturated hydrocarbons contain at least one carbon-carbon double or triple bond. under
The crystal structures of the conglomerate salts revealed that these crystals can be regarded as being a supramolecular assembly of a characteristic columnar hydrogen-bond network, in which the ammonium cations and the carboxylate anions are aligned around a twofold screw axis (21-column) . On the...
In this H-bond model, three secondary OH groups form an inequilateral hexagonal shape perpendicular to the helix axis. This hexagonal form seems to be characteristic for β-1,3-D-glucans and is widely accepted. We carried out MOPAC and ab initio calculations for the curdlan helix, and we ...
Water in confinement exhibits properties significantly different from bulk water due to frustration in the hydrogen-bond network induced by interactions with the substrate. Here, we combine infrared spectroscopy and many-body molecular dynamics simulations to probe the structure and dynamics of confined wa...
(green/cyan dotted lines); a wireframe model is used for simplicity and clarity. In the solid state, nanochannels created between stacked layers of trimers are separated by ~2.7 Å, close to the typical length of a solid-state hydrogen bond (2–3 Å). Further details of the Z...

Hydrogen is recognised as an important future energy vector for applications in many sectors. Hydrogen is an indirect climate gas which induces perturbations of methane, ozone, and stratospheric water vapour, three potent greenhouse gases. Using data fro
