Mono-dispersed DDR zeolite particles by seeded growth and their CO 2 , N 2 , and H 2 O adsorption properties

Collisional dissociation cross sections for O + O 2 , CO andN 2 , O 2 + O 2 , N + N 2 , andN 2 + N 2

Using laboratory data for the scattering of O by O2, CO and N2 pair potentials are constructed for O, C and N atoms. These potentials are then used to calculate collisional dissociation and energy transfer cross sections for O on O2, CO and N2; O2 on O2, N on N2, and N2 on N2. Since the energetic ions often neutralize in the atmosphere corona, such cross sections are relevant to plasma ion bomb...

Computational study of electronic, spectroscopic and chemical properties of Cun(n=2-8) nanoclusters for CO adsorption

First-principle calculations were carried out to investigate the adsorption of CO over Cun nanoclusters. The structural, spectroscopic and electronic properties like optimized geometries, HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energy levels, binding energy, adsorption energy, vibrational frequency and density of states (DOSs) of the p...

Production of reactive oxygen intermediates (O(2)(.-), H(2)O(2), and (.)OH) by maize roots and their role in wall loosening and elongation growth.

Cell extension in the growing zone of plant roots typically takes place with a maximum local growth rate of 50% length increase per hour. The biochemical mechanism of this dramatic growth process is still poorly understood. Here we test the hypothesis that the wall-loosening reaction controlling root elongation is effected by the production of reactive oxygen intermediates, initiated by a NAD(P...
