Relativistic effects on chemical properties [PDF]
Accounts of Chemical Research, 1979 Special or anomalous chemical effects are examined in relation to periodic-table trends, and the degree to which these are relativistic effects are determined. It is noted that the degree to which these relativistic effects and the introduction of 4f electrons (the usual textbook explanation of the anomalies) affect chemical behavior are of approx ...

Relativistic Effects in Chemical Systems [PDF]
Annual Review of Physical Chemistry, 1985 Although the velocity of light c is finite in the real world, most calculations of theoretical chemistry make the approximation c = 00. This is usually a satisfactory approximation for systems of light atoms H, C, N, 0, etc, and for most properties of chemical interest.

Chemical Effects of Ionizing Radiations [PDF]
Nature, 1948 IN 1944 it was suggested1 that the primary net process in the action of penetrating radiations (γ-rays, X-rays, etc.) on the water molecule consists in its splitting in the following way: which presumably takes place by way of the formation of H2O+ and H2O—.

Effective Chemical Processes in Porous Media [PDF]
Mathematical Models and Methods in Applied Sciences, 2003 In the book by Hornung, Chap. 6, the author proposes a homogenization strategy for the effective behavior of some chemical processes involving adsorption and reactions arising in porous media. Rigorous proofs of the convergence results are given in the case of linear adsorption rates and linear chemical reactions. The author leaves as an open question

Efficient hydrogen production through the chemical looping redox cycle of YSZ supported iron oxides
Green Energy & Environment, 2021 The chemical looping process, where an oxygen carrier is reduced and oxidized in a cyclic manner, offers a promising option for hydrogen production through splitting water because of the much higher water splitting efficiency than solar electrocatalytic ...
