Biosorption of Heavy Metal Cadmium From Aqua Medium Using Moringa Oleifera as Nature‐Based Solution
Food Safety and Health, EarlyView.The abstract explains the use of plant components of Moringa oleifera, such as seeds and leaves, for the biosorption of cadmium metal and the effect of the different variables, including pH, temperature, particle size, biomass dose, initial metal concentration, and contact time, on the adsorption process.

Geological Journal, EarlyView.Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?
Geological Journal, EarlyView.The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...
