Now available on Fast Track: Fabricating nano-sized BiVO4/InVO4/g-C3N4 photocatalysts for efficient degradation of Acid Blue 92 azo dye

Posted on 15. June, 2018.

Photocatalysis using semiconductors has received considerable interest in both the scientific and engineering areas. Especially, metal oxide semiconductor photocatalysts have been widely studied for environmental applications such as cleaning of air and the removal of hazardous compounds from wastewater. Metal vanadates are a notable category of inorganic nanomaterials that have received attention due to their wide applications and many researchers has been interested in the synthesis of metal vanadates of manganese, iron, etc.

Free for 24 hours - Kinetics and mechanism of acetalisation of furfural to furfural diethyl acetal with Ni–Al layered double hydroxides containing Lewis acid sites

Posted on 14. March, 2018.

Acetalisation is a viable method to protect carbonyl functionalities in organic compounds and offers a potential synthetic strategy for synthesising derived chemicals. Furfural diethyl acetal is an important perfume material, which is usually obtained by acid catalysis in the acetalisation of furfural to furfural diethyl acetal using ethanol as a renewable solvent.

Theoretical evaluation of the efficiency of novel frustrated Lewis pairs in the cis-hydrogenation reaction of dimethylacetylene

Posted on 9. March, 2018.

Frustrated Lewis pairs (FLPs) are the combination of Lewis acid and base motifs where steric hindrance prevents strong adduct formation. Accordingly, the ability of FLPs in small molecule activation and their capability in hydrogen cleavage led to their use in the hydrogenation of a wide range of unsaturated substrates.

A Free Review from Progress in Reaction Kinetics and Mechanism: Halocarbenes may deplete atmospheric ozone

Posted on 6. March, 2018.

The stratospheric ozone layer protects biological processes on Earth by absorbing the more harmful solar UV radiation. The discovery of the loss of stratospheric O3 led to investigations to find the cause. It was found that chlorofluorocarbons had long atmospheric lifetimes and could reach the stratosphere where they photocleaved to yield Cl atoms which destroyed O3 in a catalytic chain reaction.

Strong inhibition of the Fe3+ + H2O2 reaction by ethanol: evidence against the free radical theory

Posted on 25. February, 2018.

The effect of ethanol on the catalytic decomposition of H2O2 by Fe3+ was investigated. While expecting a simple competitive oxidation of C2H5OH, far more complex kinetics were encountered experimentally: already minute amounts of C2H5OH (1% of H2O2) had a powerful retardation effect on the disappearance of H2O2.

Halocarbenes may deplete atmospheric ozone - Free review article

Posted on 1. February, 2018.

The stratospheric ozone (O3) layer protects biological processes on Earth by absorbing the more harmful solar UV radiation, thereby preventing this radiation from reaching Earth’s surface. It was found that chlorofluorocarbons (CFCs), had long atmospheric lifetimes and could reach the stratosphere where they photocleaved to yield Cl atoms which destroyed O3 in a catalytic chain reaction.

A review on reactions of polycyclic aromatic hydrocarbons with the most abundant atmospheric chemical fragments: theoretical and experimental data

Posted on 28. November, 2017.

Aerosols are ubiquitous in the atmosphere and have strong effects on climate and public health due to the reactions of polycyclic aromatic hydrocarbon (PAH) compounds in air. Over the last decade, study of the reactions of PAHs and their derivatives in the atmosphere has become key to finding an effective way to decrease the impact of this spontaneous reaction and so reduce air pollution.

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.

Synthesis, characterisation, in vitro DNA binding properties and antioxidant activities of Ln(III) complexes with chromone-3-carbaldehyde-(2´-hydroxy) benzoyl hydrazone

Posted on 5. January, 2016.

Numerous biological experiments have demonstrated that DNA is the primary intracellular target of anticancer drugs due to the intercalation between small molecules and DNA, which can cause DNA damage in cancer cells, blocking their division and resulting in cell death. So to develop new and efficient DNA intercalators to be used as anticancer drugs is an urgent and important task.
