In this context, near-infrared spectral investigation of H-bonding in water of hydration of 1- n -alkyl-3-methylimidazolium bromides and 1-ethyl-3-methylimidazolium based amino acid ionic liquids were made through simultaneous estimation of hydration number and hydration spectra of ILs in the ...
Understanding the nature of H-bonding interactions is essential to modern sciences, such as biology, chemistry, and physics. Using density functional theory calculations, herein, we have identified two unique H-bonding types existing in a single sheet of a mixed water–hydroxyl phase on close-packe...
Why is metallic bonding important? Why does water need a specific type of bond in the body? Why is water considered a dipolar molecule? Why are covalent bonds important in living things? Why is water considered a polar molecule? What is the most important reason for the unusual properties of...
The BPM usually has the junction/bonding layer at the AML/CEL interface (Fig. 1f). The water formation at the interface may result in delamination and lead to instability of the BPM due to the difficulty in controlling the mechanical strength of the junction/bonding. In light of the above,...
Recall that it is the average parameters for an instantaneous H-bond configuration in the liquid that are given in Table 2 and compared to H-bonding in water (see for example, http://www1.lsbu.ac.uk/water/water_hydrogen_bonding. html). The larger beta angle will move the H atom ...

An unusual Fe-H bonding rather than conventional OH bonding is identified at Fe3O4 (001) surface. This abnormal behavior is associated with the oxygen vacancies which exist on the surface region but also penetrate deep into the bulk Fe3O4. In contrast, OH bonding becomes preferential as gene...

The infrared spectra of water dimers formed from H2O, D2O, and HDO in krypton matrices have been recorded. Thermal equilibria between Hand D‐bonded dimers have been studied. D bonding is preferred, and H‐bonded dimers are approximately 60 cm1 less stable than D‐bonded dimers. The energy di...
