Geminate recombination of hydroxyl radicals generated in 200 nm photodissociation of aqueous hydrogen peroxide [PDF]
Chem. Phys. Lett. 383 (2004) 481, 2005 The picosecond dynamics of hydroxyl radicals generated in 200 nm photoinduced dissociation of aqueous hydrogen peroxide have been observed through their transient absorbance at 266 nm. It is shown that these kinetics are nearly exponential, with a decay time of ca. 30 ps.

Gibberellin Metabolism in Flowering Plants: An Update and Perspectives
Frontiers in Plant Science, 2020 In plants, gibberellins (GAs) play important roles in regulating growth and development. Early studies revealed the large chemodiversity of gibberellins in plants, but only GA1, GA3, GA4, and GA7 show biological activity that controls plant development ...

Ewald methods for polarizable surfaces with application to hydroxylation and hydrogen bonding on the (012) and (001) surfaces of alpha-Fe2O3 [PDF]
Surface Science, 385 (1997) 217-239., 1997 We present a clear and rigorous derivation of the Ewald-like method for calculation of the electrostatic energy of the systems infinitely periodic in two-dimensions and of finite size in the third dimension (slabs) which is significantly faster than existing methods.

Effect of Alkyl Substituents on the Hydrogen Catalytic Osmylation of Cis and Trans 2-Cyclohexene-Cyclohexanol [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 1995 Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3).

Proline hydroxylation in collagen supports integrin binding by two distinct mechanisms
Journal of Biological Chemistry, 2018 Collagens are the most abundant extracellular matrix proteins in vertebrates and have a characteristic triple-helix structure. Hydroxylation of proline residues is critical for helix stability, and diminished prolyl hydroxylase activity causes wide ...
