Mechanism of covalent adsorption of benzenesulfonamide onto COOH– and COCl– functionalised carbon nanotubes

Posted on 6. April, 2016.

The use of carbon nanotubes (CNTs) in drug delivery is a new, rapidly developing field. Different systems such as polymers, dendrimers, and liposomes have been used for drug delivery, but carbon nanotubes provide more effective structures due to their high drug loading capacities and good cell penetration qualities.

Kinetic and mechanistic aspects of ligand substitution on cis- diaqua (cis-1,2-diaminocyclohexane)platinum(II) with three glycine-containing dipeptides

Posted on 7. August, 2014.

The discovery of cisplatin as an anticancer agent marks the beginning of the upsurge of interest in the use of metal complexes in cancer chemotherapy. However, cisplatin has a narrow spectrum of activity, and its clinical use is limited by undesirable side effects, including nephrotoxicity, ototoxicity, neurotoxicity, nausea, vomiting, and myelosuppression.

Computational mechanistic study of the gas phase oxidation of methanol with ozone

Posted on 31. July, 2014.

One important aim of modern combustion chemistry is to design and analyse possible new forms of non-petroleum-based fuel or fuel components for use in combustion engines.Methanol can be considered as one of the simplest oxygenated hydrocarbon compounds in this regard.

Density functional theory study on the mechanism of absorption of CO2 by the ionic liquid 1‑butyl‑3‑methylimidazolium acetate

Posted on 25. June, 2014.

The atmospheric concentration of CO2 has increased unabated primarily due to the CO2 emissions from the combustion of fossil fuels in large stationary emitters like power plants. The flue gas of power plants contains of the order of 10% CO2 at near ambient pressure.

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.

Pyrolysis of trifluoromethane over activated carbon: role of the surface oxygen groups

Posted on 12. May, 2014.

Trifluoromethane (CHF3, HFC-23) is the major byproduct during the manufacture of HCFC-22 (CHClF2) which is one of the key feedstocks for the production of various materials, such as PTFE, PVDF, refrigerants, fire extinguishing agents and foams.

Mechanism of DNA cleavage catalysed by the system comprising an unsaturated tetraaza macrocycle and La(III) and Ce(III) ions

Posted on 7. May, 2014.

Phosphate esters are essential to any living organism and their specific hydrolysis plays an important role in many metabolic processes.

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.
