Interaction between ethylene and O– centres on magnesium oxide surfaces gives a radical having a nearly isotropic hyperfine coupling to two equivalent hydrogen atoms (58 G), a very weak coupling to a single proton, and ...

Methacrylic acid-divinylbenzene copolymer is a more powerful catalyst for the hydrolysis of ethyl vinyl ether than for the hydrolysis of dimethyl acetal. Comparison of the reactions indicates that for ethyl vinyl ether ...

The thermal stability of NH4-chabazite has been examined by i.r. spectroscopy and thermal analysis combined with mass spectrometry. Dehydration occurs in two and deammoniation in four steps. Disregarding a very small water ...

The reaction of oxygen atoms with methyl nitrate and with ethyl nitrate have been studied in a discharge–flow system at temperatures between 294 and 473 K. The initial attack involves abstraction of a hydrogen atom for ...

The photoredox reaction between thionine and iron (II) has been studied by flash photolysis techniques. The principal reaction intermediate is the semithionine radical anion which decays via a dismutation process forming ...

The frequency of oscillation of the Belousov-Zhabotinskii reaction (oxidation of malonic acid by bromate ions in acidified solution containing cerium ions) depends on the initial concentration of reactants, but in each ...

A novel “cataluminescent” effect is described in which rare earth activators introduced into the catalyst thoria are electronically excited during carbon monoxide oxidation and emit a light very similar to that given by ...

Twisted electron-impact single ionization ((e,2e) process) of water molecule is theoretically studied in the presence of an external laser field. Calculations have been performed in the framework of the first Born approximation ...

Emission properties of the Astrophysical objects such as Neutron Stars are found using mass, pressure profile and thermal cooling rate. In this current work, we determine the cooling rate of spherically symmetric neutron ...

The total vapour pressure of the systems hydrogen bromide+xenon and hydrogen bromide + hydrogcn chloride have been measured as a function of composition at 195.42 K. The results have been used to estimate the excess ...
