O, and C-H...O hydrogen bonds in protein-ligand complexes: strong and weak interactions in mole- cular recognition. Proteins: Struct. Funct. Genet. 54, 247-259.Sarkhel, S., and Desiraju, G. R. (2004) N - H...O, O - H...O, and C - H...O hydrogen bonds in protein-...
Mechanism of Fenton reaction, which is a most widely-used degradation test for organic materials using hydrogen peroxide (H2O2) and iron (Fe) cations, is revealed for the decomposition of hydrated Nafion membrane. This reaction mechanism has been assumed to generate OH radicals. For a doubly-hydr...
We have reported a homologous series based on manganese complexes of dpa ligand that contains aqua molecules either as a coordinating ligand or as water of crystallization, displaying strong hydrogen bonded networks. This study also shows the use of the N–H group of dpa as a strategy to harnes...
from 10 K to 300 K. In Fig.4c, the PL peak (523 nm) at 10 K is as narrow as 6.8 nm, which originates from the emission of a typical strong excitonic recombination31. With the increasing temperature, the intensity of the peak centered at 530 nm (at 10 K) gradual...

Yvonite, Cu(AsO 3 OH)2H 2 O, was found in the Salsigne mine near Carcassone (Aude, France). It forms aggregates or radiating spherules consisting of individual crystals (maximal size 0.3 × 0.15 × 0.06 mm) of turquoise blue color. They are elongated in
At the 683 cm−1 peak, a weak feature was observed due to water molecules’ bending vibrations mode −δOH. Further, except for the 1000 cm−1 below the peak, other FTIR spectra peak were similar. The LC-3 (Figure 3c) spectrum certified the case that the nanoprisms were made out...
Perturbations in relevant cellular functions appears to have a strong correlation with cancerous cell growth, but it remains to be addressed whether these are also causative. Furthermore, the precise role of the specifically modified nucleotides is insufficiently known in relation to protein biosynthesis...

Factors responsible for the weaker O-H bond of 1, such as differences in the electron-donating properties of the ligand, metal ion Lewis acidity, and electronic structure, are discussed.EBSCO_AspJournal of the American Chemical Society
