Effect of temperature and catalyst type on the catalytic combustion of formaldehyde

Posted on 10. June, 2014.

Recent, environmental legislation has imposed increasingly stringent targets for permitted levels of atmospheric emissions. Volatile organic compounds (VOCs) are a wide-ranging class of chemicals occurring in commercial waste streams, and currently over 300 compounds are classed as VOCs by the US EPA.

Theoretical and experimental studies on regioselectivity of epoxide ring opening by nucleophiles in nitromethane without any catalyst: nucleophilic-chain attack mechanism

Posted on 11. March, 2014.

In nature, epoxide ring opening is catalysed by the phenolic proton of a tyrosine moiety, but in the research laboratory, the cleavage usually occurs in non-aqueous media in the presence of a Lewis acid catalyst.

Reaction mechanisms for the heterogeneous hydrogenolysis of biomass-derived glycerol to propanediols

Posted on 24. February, 2014.

Biomass-derived glycerol is emerging as a renewable, cheap and versatile feedstock for the production of a variety of chemicals and fuels. In particular, hydrogenolysis of glycerol to other value-added chemicals over heterogeneous catalysts has been extensively studied in the past few years. The most desired products arising from this process are propanediols, i.e. 1,2-propanediol and 1,3-propanediol.

A Kinetic model of proton transport in a multi-redox centre protein: cytochrome c oxidase

Posted on 21. February, 2014.

Cytochrome c Oxidase (CcO) is the final complex of the respiratory chain. Its purpose is to use the energy gained by the reduction of oxygen to water to pump protons against a difference of electrochemical potentials across the mitochondrial inner membrane.

First Principles Kinetics Of n-Octyl Radicals

Posted on 18. February, 2014.

Being the initial product from radical attack on alkanes, alkyl radicals are important intermediates in the decomposition of organic fuels. It has long been known that alkyl radicals reactions play an important role in the combustion and atmospheric degradation pathways of traditional fuels as well as a wide variety of other chemical processes.

Novel approach to the ultrasonic degradation of polymers: development of a general kinetic equation

Posted on 14. January, 2014.

The general applicability of the common kinetic equations is discussed to develop a general kinetic equation for the ultrasonic degradation of polymers. The common ultrasonic-kinetic equations for polymers are used to fit original data collected from the literature. The fitting accuracy is evaluated by the residual standard deviation. The results indicate that the first-order equation and second-order equations are the most accurate and can replace other kinetic equations.
