(2007)Reaction cross sections for proton-nucleus elastic scattering are investigated within a nonrelativistic microscopic approach for the nucleon-nucleus optical model potential. Applications were made for nucleon energy ...
-
(KeAi Publishing Communications Ltd., 2019)Typically, a Lewis acid and a Lewis base can react with each other and form a classical Lewis adduct. The neutralization reaction can however be prevented by ligating the acid and base with bulky substituents and the ...
-
(Wiley-Hindawi, 2021)Endosymbiosis is a type of symbiosis where one species of microscopic scale inhabits the cell of another species of a larger scale, such that the exchange of metabolic byproducts produces mutual benefit. These benefits can ...

-
(1989)DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), a hydroxamic acid from cereals, reacted with primary amines to give an addition compound with two imino groups. Kinetic studies with DIMBOA and with the DIMBOA analogues ...
-
(ELSEVIER SCIENCE, 2005-10-31)Detection of O-2((1)Delta(g)) emission, lambda(max) = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, k(T), and the reactive reaction rate constant, ...
-
(2005)Detection of O2(1Δg) emission, λmax = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, kT, and the reactive reaction rate constant, kR, for the reaction ...
-
(1978)Kinetic studies of the [Co(phen)3] (ClO4)3 2H2O nitromethane pyridine reaction were made spectrophotometrically, by recording the appearance of a new absorption band at 474 nm. The reaction is first order with respect to ...
