In this study, the recent micro-extraction and pre-concentration techniques, namely vortex-assisted liquid-liquid micro-extraction (VA-LLME), dispersive liquid-liquid micro-extraction (DLLME) and membrane assisted solvent ...
Glitazones are derivatives of thiazolidine with two carbonyls at 2- and 4-positions. Replacing the thio group with amino group gives rise to hydantoins while replacing carbonyl group at positions 2 with the thio group ...
Host-guest chemistry, also known as inclusion chemistry, is an important subfield of supramolecular chemistry where there is great current interest owing to its great promise in the areas of separation of small molecules, ...
Na2Fe2(MoO4)3 is a good cathode material for sodium storage due to its low cost, non-toxicity of iron and three open dimensional crystal framework. Na2Fe2(MoO4)3 was synthesised using the one pot sol-gel method. Na2Fe2(MoO4)3 ...
The Solanum genus is among the most diverse and valuable in terms of agricultural utility and vegetable crops. This study was directed at the characterization of toxic metabolites contained in Solanum retroflexum and Solanum ...
1,2,4-Triazine and its derivatives have proven their importance in the biological world since they are used in the treatment of diseases like cancer and HIV/AIDS. Thus this project was aimed at synthesizing novel ...
This research study reports the inhibition of mild steel (MS), zinc (Zn) in 1.0 M HCl and 1.0 M H2SO4, and the inhibition of aluminium (Al) in 0.5 M HCl by three selected quinoxaline derivatives namely, quinoxalone-6-carboxylic ...
Metal-organic frameworks (MOFs) have been identified as promising physisorption candidates because of their unique structures. MOFs are a class of crystalline materials consisting of coordinate bonds between metal ions and ...
In this study, modern clean-up and pre-concentration techniques, namely hollow fibre liquid phase micro-extraction (HFLPME) and miniaturized pipette-tip extraction based on molecularly imprinted polymers (m-MIP-PTE), were ...
Antibiotics and perfluoroalkyl substances (PFAS) are groups of anthropogenic substances that are found in industries and consumer products, i.e., antibiotics are used in healthcare facilities, pharmaceutical companies, and ...
South Africa consumes more than 100 million tons of low-grade coal annually to produce electricity. This process results in generation of vast amounts of waste ash in coal fly ash (CFA) which is voluminous and is a source ...
Extraction and purification of target compound or analytes from the matrices is always a goal to achieve in different industries and fields of study. Therefore, there is always a need to purify the desired product to get ...
Chromones are a group of naturally occurring heterocyclic compounds, with oxygen as a heteroatom. However, chromone-2-carboxylates are scarce in nature. These compounds are significant in organic chemistry and medicinal ...
The contamination of the environment with wastewaters emanating from different operations and industrial activities has been an issue of prime concern to national and international research communities. Grossly, acid mine ...
Li3VO4 has been considered a promising negative electrode material because of its high theoretical capacity (394 mAh g−1) and zero strain during the charge and discharge processes. However, the electronic conductivity of ...
In this work, new clean sorbent that has greater selectivity was used in the determination of pesticides residues in complex matrices at the desired limits of quantification. This work is divided into 3 papers focusing on ...
Acceptable energy storage technologies are needed for the transition from fossil fuels to renewable energy sources, which can be expected to take place over the next 30 years. Lithium-ion batteries are used extensively but ...
Computational studies are very important for biologically active molecules and for the development of new drugs, because the biological activities depend on their molecular structures and properties. This work presents the ...
Metal-organic frameworks (MOFs) are a class of crystal engineered materials consisting of organic and inorganic units. They are made up of metal ions connected by bridging ligands to form three dimensional (3D) networks. ...
In this study, the corrosion inhibition potentials of three flavonoid derivatives namely Naringenin (NRNG), Morin hydrate (MNHD) and 6-Hydroxyflavone (6-HFN) for zinc and aluminium metals was investigated using gravimetric ...
