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 ... -
A green synthesis of zinc oxide nanoparticles using Musa paradisiaca and Rooibos extracts
(Elsevier, 2022)This study describes the single pot synthesis of zinc oxide nanoparticles (ZnO NPs) using a mixture of Aspalathus linearis and Musa paradisiaca for use against the fungi Candida albicans. These nanoparticles are known to ... -
Green synthesized saunps as a potential delivery platform for cytotoxic alkaloids
(MDPI, 2023)The use of natural products as chemotherapeutic agents is well established. However, many are associated with undesirable side effects, including high toxicity and instability. Previous reports on the cytotoxic activity ... -
Green tea (Camellia sinensis) aqueous extract improved human spermatozoa functions in vitro
(ResearchGate, 2022)Background: Idiopathic causes of infertility is associated with oxidative stress. Antioxidants are known to scavenge the excessive production of reactive oxygen species (ROS). Green tea (Camellia sinensis) contains polyphenols ... -
Green tea consumption increases sperm concentration and viability in male rats and is safe for reproductive, liver and kidney health
(Springer Nature, 2020)Green tea is a popularly consumed beverage worldwide and contains polyphenols, whose antioxidant activities could improve sperm parameters and fertility thereof. We investigated the effect of green tea on the male rat ... -
Green-synthesized zinc oxide nanoparticles mitigate salt stress in sorghum bicolor
(MDPI, 2022)Salinity is an abiotic stress that is responsible for more than 50% of crop losses worldwide. Current strategies to overcome salinity in agriculture are limited to the use of genetically modified crops and chemicals ... -
Greener on the other side: Tracing stories of amaranth and moringa through indenture
(Taylor and Francis Group, 2023)My research, with its focus on women and food seed through the lens of indenture, has led me into the world ofleafy green vegetables and their intimate connection to women who had been brought to South Africa to servicecolonial ... -
