The optimized geometrical structures, the interaction energies, the basis set superposition errors (BSSEs) and the infrared spectra of the monomers, homodimers and the molecular complexes formed between BF3 and a number of ...

Binuclear mixed biscarbene complexes of bithiophene were synthesized via the classical Fischer method of synthesis. The metal carbonyls, Mo(CO)6, Cr(CO)6, W(CO)6 and Mn(MeCp)(CO)3 were reacted with dilithiated bithiophene ...

Emerging contaminants (EC) are unregulated substances that have entered the environment for as long as they have been produced through human activities. Within the ECs family, pharmaceuticals and personal-care products ...

An environmentally friendly, rapid and cost effective analytical procedure based on dispersive liquid-liquid microextraction was developed for the determination of six tetracyclines (TCs) in meat destined for human ...

The use of veterinary drugs continues to be a challenge since some farmers use drugs for medicinal purposes, while others use them as growth promoters without observing the set withdrawal times. In emerging economies, ...

Magnesium hydroxide, a stable flame retardant, can be obtained by mining or by the hydration of magnesium oxide. In this study, the effect of different hydrating agents on the pH of the hydrating solution, rate of hydration ...

South Africa is classified as a water-stressed country and is faced with widespread water scarcity. Water scarcity is worse in rural areas of the country where a third of the population still reside. This is due to low ...

Anti-androgens (AAs) are a class of pharmaceutical drugs used to treat prostate cancer. Over the years, prostate cancer has been reported as the most frequent cancer diagnosis in men and the leading cause of mortality ...

The use of magnesium hydroxide (Mg(OH)2) as a flame retardant and smoke-suppressor in polymeric materials has been of great interest recently. Because it contains no halogens or heavy metals, it is more environmentally ...

Marshy soil and sediment samples were collected during dry and rainy seasons within Warri, and Agbarho, 20km away as control. Levels of 16 USEPA priority Polycyclic Aromatic Hydrocarbons PAHs were determined using GC-FID. ...
