From high school to distinguished professor of chemistry at Rhodes University, Tebello Nyokong discusses her inspiration and ambitions to promote science in South Africa.
As researchers explore innovative ways to make nuclear fuels more accident-tolerant, this report investigates the use of manganese ions as dopants for uranium oxide (UO2) fuels.
Typically thought of as inert and non-participating atoms, noble gasses adsorbed onto freshly cleaved single crystal surfaces enhance their electronic band structures, potentially creating more active heterogeneous catalysts.
The Chemical Weapons Convention has a unique Scientific Advisory Board that ensures it keeps pace with science, and its implementing body is prepared for future challenges. It is a model that could be usefully applied to other disarmament treaties.
Semiconducting polymers require narrow molecular weight distributions for optimal efficiency. Synthesizing such polymers is no easy task, however a combined ultrasonication-assisted Stille polymerization reaction could be the solution to this problem.
Chemistry education research is a well-established field that has the potential to inform chemistry teaching at all levels. But to the uninitiated, much of the work can seem descriptive while quantitative studies often suffer from a lack of reproducibility. Here I delve into these characteristics and explain why this should not deter chemistry teachers from engaging.
Providing a stable and reliable supply of electrons is crucial for the future of quantum computing processors. Here, electron withdrawing groups are added to species which improve the flow of electrons.
The reduction of molecular species containing arene to alkali metal cation interactions with other alkali metals has been found to contradict the expectation provided by simple considerations of relative reduction potentials.
By drawing inspiration from ion transport in biology, researchers have developed highly selective channels for the separation and enrichment of Li+ ions from complex aqueous solutions.
The European BorderSens project leverages voltammetric sensors, developed with end-users’ input, to rapidly and accurately detect illicit drugs. By embracing practicalities and validation, this technology has the potential to combat the illicit drug problem.
Cable bacteria are able to conduct electrons to interconvert oxygen and water. Here, researchers have isolated the conducting cable bacteria skeletons to demonstrate their activity in an electrochemical cell.
If intense ionizing radiation was present at a time of prebiotic life, protocells would have needed protection. Researchers have shown that peptide-containing coacervates can harbour DNA strands, which can then be coated with Mn-containing coacervates protecting the interior from radiation.
