Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

First Phosphonic‐Type Inhibitors and Activity‐Based Probes Specific to the O'nyong‐nyong Virus Capsid Protease

open access: yesChemMedChem, EarlyView.
The serine capsid protease (CP) catalyzes a crucial process of the alphaviral replication cycle; therefore, it constitutes an interesting therapy target. Herein, the O'nyong‐nyong virus CP profile activity with a specific fluorogenic substrate is analyzed and examines the inhibitory activity of a new series of phosphonic analogs of tryptophan and ...

Uranium isotopes quantitatively determined by modified method of atomic absorption spectrophotometry [PDF]

open access: yes, 1967
Hollow-cathode discharge tubes determine the quantities of uranium isotopes in a sample by using atomic absorption spectrophotometry. Dissociation of the uranium atoms allows a large number of ground state atoms to be produced, absorbing the incident ...
