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 ... -
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 ... -
Ground-based Ku-band microwave observations of ozone in the polar middle atmosphere
(Copernicus Publications, 2021)Ground-based observations of 11.072 GHz atmospheric ozone (O3) emission have been made using the NyÅlesund Ozone in the Mesosphere Instrument (NAOMI) at the UK Arctic Research Station (latitude 78 550000 N, longitude 11 ... -
Groundwater discharges to aquatic ecosystems associated with the Table Mountain Group (TMG) aquifer: a conceptual model
(Water Research Commission, 2008)This paper reports on a conceptual model that was developed to describe the different groundwater discharge ‘types’ from the Table Mountain Group (TMG) aquifer, that contributes to the different components of the flow ... -
Groundwater management issues in Southern Africa – An IWRM perspective
(Water Research Commission, 2008)In contrast to its strategic role as essential resource to help achieve community development and poverty alleviation in the Southern African Development Community (SADC), groundwater has remained a poorly understood and ... -
Groundwater prediction using machine-learning tools
(MPDI, 2020)Predicting groundwater availability is important to water sustainability and drought mitigation. Machine-learning tools have the potential to improve groundwater prediction, thus enabling resource planners to: (1) anticipate ... -
