Workplace violence against healthcare workers during the COVID-19 pandemic in Sudan: A cross-sectional study.

Background: Workplace violence (WPV) against healthcare workers (HCWs) is a growing global issue. During the coronavirus diseases-2019 (COVID-19) pandemic, violent attacks on HCWs have been documented worldwide. This study aimed to investigate the magnitude and pattern of WPV among HCWs in Sudan during the COVID-19 pandemic.

Facile synthesis of mesoporous nano Ni/NiO and its synergistic role as super adsorbent and photocatalyst under sunlight irradiation.

Tailoring a material that has a synergistic role as an adsorbent and a photocatalyst for environmental application is an attractive field for research. This article presents a study of facile synthesis of NiO and Ni/NiO with a synergistic role as super adsorbents in the lake of light and photocatalysts under light irradiation. Nano flower-like mesoporous NiO and Ni/NiO were synthesized by the co-precipitation method.

Cost-effective adsorbent from arabinogalactan and pectin of cactus pear peels: Kinetics and thermodynamics studies.

Cactus pear peel as agricultural waste containing arabinogalactan and pectin was thermally treated at 300 °C for 4 h and the resultant carbonized material was applied as adsorbent for the removal of methylene blue dye as a model cationic dye. The prepared adsorbent was characterized by means FTIR for structural characterization, N physisoprtion measurements for texture properties, SEM and EDAX for morphological and elemental analysis. The characterization results clearly show that the prepared material is porous with several -OH and CO terminals.
