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 ...
This study is based on the synthesis of four Thiazolidinediones (TZD) derivatives which are Ethyl 2-(5-(4-methoxybenzylidene)-2,4-dioxothiazolidin-3-yl)acetate (EMDA), Ethyl 2-(5-(Benzo[d][1.3]dioxol-5ylmethylene)-2,4dio ...
Many researchers have put their efforts in developing various types of sulphate-based cathode materials for lithium-ion batteries such as Li2Co(SO4)2, Li2Mn(SO4)2, Li2Fe(SO4)2 and many others. This study focuses on the ...
This study focuses on investigating three chromone derivatives namely; 3-cyanochromone (3CYC), 6-methylchromone-2-carboxylic acid (6MC2C), and 6methylchromone hydrate (6MCH) as corrosion inhibitor for three metals namely, ...
In this study, a class of inorganic materials Li3VO4, Li3-xNaxVO4, Li3-xKxVO4, LiV1-yCryO4, and Li3-xKxV1-yCryVO4 (where x = 0.01, 0.05 & 0.1; y = 0.01, 0.05 & 0.1) were effectively synthesized via citrate sol – gel method. ...
Ethnobotanical surveys have shown that K. wilmsii is used traditionally for the treatment of
hypertension, diabetes, fever, hypertension, malaria, toothache and diabetes mellitus. Despite all
this interesting information, ...
Quinolines are well known naturally occurring heterocyclic compounds with nitrogen as a heteroatom. Quinolines are also one of the major classes of naturally occurring compounds and the interest in their chemistry is due ...
In this study, carboxylic acid and two ionic liquids-based amino esters were used as corrosion inhibitors for aluminium and mild steel. These compounds were selected because they are said to be non-toxic and environmentally ...
