Approaches to mitigation of hydrogen sulfide during anaerobic digestion process - A review.

Anaerobic digestion (AD) is the primary technology for energy production from wet biomass under a limited oxygen supply. Various wastes rich in organic content have been renowned for enhancing the process of biogas production. However, several other intermediate unwanted products such as hydrogen sulfide, ammonia, carbon dioxide, siloxanes and halogens have been generated during the process, which tends to lower the quality and quantity of the harvested biogas.

Chemical profiling of from eleven Tanzanian regions.

The aim of this research was to investigate the chemical profiles of from 11 Tanzanian regions using preliminary tests as well as instrumental analyses with GC-MS and LC-MS. Generally, all the seized samples tested positive for the presence of (Δ-THC. The preliminary test with Duquenois method followed by chloroform addition revealed the presence of Δ-tetrahydrocannabinol (Δ-THC) in all the samples.

A comparative in-vitro study on antimicrobial efficacy of on-market alcohol-based hand washing sanitizers towards combating microbes and its application in combating Covid-19 global outbreak.

The coronavirus disease 2019 (COVID-19) outbreak has created endless social, economic, and political fear in the global human population. Measures employed include frequent washing hands and using alcohol-based hand sanitisers and hand rubs as instant hand hygiene products. Due to the need to mitigate the pandermic, there is an increase in the local production of alcohol-based hand sanitisers, whose quality and efficacy against germs and the virus are questionable.

Towards attaining SDG 6: The opportunities available for capacitive deionization technology to provide clean water to the African population.

The unavailability of clean water caused by population growth, increased industrial activities, and global climate change is a major challenge in many communities. A number of desalination technologies including distillation, reverse osmosis and electrodialysis, have been used to supplement the available water resources. However, these technologies are energy intensive and demand a significant financial commitment.
