Meson-meson nonresonant reactions governed by the quark-interchange mechanism are studied in a potential that is derived from QCD. S-wave elastic phase shifts for I = 2 ππ and I = 3/2 Kπ scattering are obtained with wave functions determined by the central spin-independent term of the potential. The reactions include inelastic scatterings of two mesons in the ground-state pseudoscalar octet and...

In this study, we aim to prepare a highly selective fluorine adsorbent by mechanochemical treatment from two types of titanium oxides, rutile and anatase. Fluorine adsorption the products anatase increased for 60 min regardless ball diameter used in treatment, were 1.5 2.0 times higher than those raw materials, respectively. With decreasing pH 2-3, on maximum at 2-3. The can remove fluoride ion...

The design of solid metal catalysts using theoretical methods has been a long-standing goal in heterogeneous catalysis. 2] Recent developments in methodology and computer technology as well as the establishment of a descriptor-based approach for the analysis of reaction mechanisms and trends across the periodic table allow for the fast screening for new catalytic materials and have lead to firs...

Inertial homeothermy, the maintenance of a relatively constant body temperature that occurs simply because of large size, is often applied to large dinosaurs. Moreover, biophysical modelling and actual measurements show that large crocodiles can behaviourally achieve body temperatures above 30°C. Therefore it is possible that some dinosaurs could achieve high and stable body temperatures withou...

One of the main issues that has limited use hydrogen as an energy vector for a long time is its low density per unit volume. Alternative chemical storage methods have been developed in recent years to overcome limitations associated with compressed or liquified storage. these Liquid Organic Hydrogen Carrier (LOHC), which utilizes organic hydrocarbons can capture (through exothermic hydrogenatio...
