These observations are consistent with the formation of symmetric hydrogen bonds and a new phase, Ice X, with cuprit structure.doi:10.1016/0375-9601(84)90510-3K.R HirschW.B HolzapfelElsevier B.V.Physics Letters AK. R. Hirsch and W. B. Holzapfel, Phys. Lett. A , 1984, 101 , 142...
were found in the homozygous state among 140,000 individuals on gnomAD, a database that removes individuals affected by severe pediatric disease, indicating that biallelic pathogenic variants are likely incompatible with normal development. Twenty-five of the variants are found in the coding sequence, ...
and the Kyte-Doolittle hydropathy scale48denoting hydrophilicity (feature #3) were introduced as features to describe the hydrophobic interactions. The isoelectric point of an amino acid (feature #4) was selected to describe electrostatic properties. Hydrogen bonding was described by the number of elec...
Raman spectra of ice VII and X were investigated using strong plasma shockwave generated by laser-induced breakdown (LIB) in liquid water. Simultaneously, the occurrence of the hydrogen emission lines of 656nm (Hα), 486nm (Hβ), 434nm (Hγ) and 410nm (Hδ) was observed. At 5 × ...

Curcumin is a polyphenol of the Curcuma longa plant, which can be used for various medicinal purposes, such as inflammation and cancer treatment. In this context, two symmetric curcumin derivatives (D1—(1E,6E)-1,7-bis(4-acetamidophenyl)hepta-1,6-diene-3
Graphite fine powder 99.99% (Extra pure) (7–20 µm), sulfuric acid 98% (H2SO4), potassium permanganate 99.5% (KMnO4), sodium nitrate 99% (NaNO3), 30% purified hydrogen peroxide (H2O2) were purchased from Sigma–Aldrich. The doping precursors, urea (CH4N2O) and thiourea (CH4N2S), ...
In presence of Lanthanide ions the neutral complexes do not coordinate to the LnIII ions, the oxygen atom of the oxime function being only hydrogen-bonded to a water molecule that is linked to the LnIII ion. This surprising behavior allows for the isolation of LnIII ions by non-interacting...
Physicochemical trends were observed in each series with the same heterocyclic substituents as well as with the same N-alkyl side chain. Compounds 6d, 6i, 6n with the methoxy substituent showed the lowest logD, due to its ability to form hydrogen bonds. Slightly higher values were observed ...
