Population-based genomics studies have proven successful in identifying genetic variants associated with diseases. High-quality biospecimens linked with informative health data from diverse segments of the population have made such research possible. However, the success of biobank research depends on the willingness of the public to participate in this type of research. We aimed to explore the factors associated with the willingness of the public to participate in biobank research from four low- ...

Many metals and minerals are the backbone of the clean energy transition. However, its extraction and production are known to be a source of various environmental impacts. The use of a multicriteria assessment tools such as life cycle assessment (LCA) to evaluate the environmental impacts of the production of these elements is still poorly developed. Therefore, science-based decisions to achieve carbon neutrality are limited as the whole life cycle is generally not considered. This systematic review ...

Oxovanadium (IV) bis-Schiff base complex was synthesized by a facile complexation of 2 molar ratio of 2‑hydroxy-Schiff base ligand (HL) with 1 molar ratio of VO2+ ion giving mononuclear VOL2 complex with a square pyramidal geometry. The structure conformation of HL and its corresponding VOL2 complex was assigned within various spectroscopic tools (IR, UV–vis. Mass spectra), as well as the elemental analyses (EA). The deprotonated 4-OH group in VOL2 caused a successful coating of VOL2 on a mixed oxides ...
