A review of the green synthesis of zno nanoparticles utilising Southern African indigenous medicinal plants
(MDPI, 2022)
Metal oxide nanoparticles (NPs), such as zinc oxide (ZnO), have been researched extensively
for applications in biotechnology, photovoltaics, photocatalysis, sensors, cosmetics, and
pharmaceuticals due to their unique ...
Microscopic, spectroscopic, and electrochemical characterization of novel semicrystalline poly(3-hexylthiophene)-based dendritic star copolymer
(MDPI, 2022)
In this study, electron-donating semicrystalline generation 1 poly(propylene thiophenoimine)-
co-poly(3-hexylthiophene) star copolymer, G1PPT-co-P3HT was chemically prepared for the first time.
Copolymerization was ...
Fusion-assisted hydrothermal synthesis and post-synthesis modification of mesoporous hydroxy sodalite zeolite prepared from waste coal fly ash for biodiesel production
(MDPI, 2022)
Increases in biodiesel prices remains a challenge, mainly due to the high cost of conventional oil feedstocks used during biodiesel production and the challenges associated with using
homogeneous catalysts in the process. ...
Polyethylene glycol (peg-400): An efficient one-pot green synthesis and anti-viral activity of novel α-diaminophosphonates
(Taylor & Francis Online, 2019)
An efficient and eco-friendly protocol has been accomplished for a series of novel a-diaminophosphonates by a one-pot, three-component system via Kabachnik-Fields reaction of 4,40 -methylenedianiline, a variety of ...
Green synthesis of silica and silicon from agricultural residue sugarcane bagasse ash – A mini review
(Royal Society of Chemistry, 2023)
Silicon dioxide (SiO2), also known as silica, has received attention in recent years due to wide range of capable applications including biomedical/pharmaceutical, energy, food, and personal care products. This has accelerated ...
Complexation-based detection of nickel(ii) at a graphene-chelate probe in the presence of cobalt and zinc by adsorptive stripping voltammetry
(MDPI, 2017)
The adsorptive stripping voltammetric detection of nickel and cobalt in water samples
at metal film electrodes has been extensively studied. In this work, a novel, environmentally
friendly, metal-free electrochemical ...
2-Arylnaphthoquinone analogues: Potential anti-TB and pro-apoptotic agents
(Green, I. R. et al. (2011). 2-Arylnaphthoquinone analogues: Potential anti-TB and pro-apoptotic agents. ARKIVOC, (x), 192-212. https://doi.org/10.3998/ark.5550190.0012.a16, 2011)
A useful library of substituted 2-arylnaphthoquinones prepared by reaction between the
corresponding bromonaphthoquinones and arylboronic acids via Suzuki-Miyaura protocols has
been established. Conversion of some of the ...
Palladium-gold nanoalloy surface modified limn2o4 cathode for enhanced li-ion battery

Role of the methoxy group in product formation via TiCl4 promoted 4-phenyldioxolane isomerizations
(ARKAT USA INC, 2010)
The product distribution obtained from the TiCl4 initiated intramolecular isomerizations of 4-
methoxyphenyl- and trimethoxyphenyldioxolanes at -78 oC, -30 oC and 0 oC provided insights
into the important regiochemical ...
