Characterization of polymorph transformations that decrease the stability of tablets containing the who essential drug mebendazole
(Elsevier, 2010)This study investigated the influence of moisture and heat on the stability of mebendazole polymorph C in tablets. The polymorphic forms of mebendazole display significant differences in solubility and therapeutic efficacy ... -
Co-pyrolysis of coal and raw/torrefied biomass: a review on chemistry, kinetics and implementation
(Elsevier, 2021)Thermochemical conversion via co-pyrolysis has the potential to be an efficient route for converting biomass to bio-energy and bio-refinery products. In this review, the implementation of co-pyrolysis of torrefied biomass ... -
CO2 reactivity of briquettes derived from discard inertinite-rich Highveld coal using lignosulphonate and resin as binders
(SAIMM, 2019)South African collieries generate approximately 31 Mt of fine and ultrafine coal annually, with the majority of the ultrafine fraction discarded in slurry ponds and underground workings. Use can be made of this energy ... -
Comparison of xenobiotic metabolism in phase I oxidation and phase II conjugation between rats and bird species
(Elsevier, 2018)There have been many reports regarding toxic chemicals in birds. Chemicals are mainly metabolized in the liver through phase I oxidation by cytochrome P450 (CYP) and phase II conjugation by conjugated enzymes, such as ... -
A kinetic expression for the pyrolytic decomposition of polyterafluoroethylene
(Elsevier, 2008)Despite the fact that the thermal decomposition of polytetrafluoroethylene has been extensively studied over the past six decades, some inconsistencies regarding the kinetic parameters, e.g. the order of the reaction, ... -
Preparation and transformation of true nifedipine polymorphs: investigated with differential scanning calorimetry and X-Ray diffraction pattern fitting methods
(Elsevier, 2011)The amorphous → metastable and metastable → stable crystalline phase transitions of nifedipine and their relationship with polymorph composition during storage at controlled temperature/humidity conditions were investigated. ... -
Rapid cell lysis and DNA capture in a lysis microreactor
(Elsevier, 2012)In clinical diagnostics, the detection and identification of bacterial organisms based on the analysis of their nucleic acids require cell lysis and DNA extraction from clinical samples. A lysis microreactor (LMR) has been ... -
Removal of naphthalene from simulated wastewater through adsorption-photodegradation by ZnO/Ag/GO nanocomposite
(Elsevier, 2020)In this study, a ZnO/Ag/GO nanocomposite was synthesised and used as photocatalyst for effective photodegradation of naphthalene from simulated wastewater under visible light. Chemical and morphological characterisation ... -
Solid state concerns during drug discovery and development: thermodynamic and kinetic aspects of crystal polymorphism and the special cases of concomitant polymorphs, co-crystals and glasses
(Bentham Science, 2017)During drug discovery and development the thermodynamics and kinetics of crystal form transitions must be studied and the fundamental properties of polymorphs must be identified. However, despite the accumulation of knowledge ...
