Organic Solvent Permeation through Negatively Charged Graphene Oxide Membranes

Graphene oxide (GO) has emerged as a promising membrane material for organic solvent nanofiltration. This study aims to understand the permeation behaviors of five polar organic solvents [namely, methanol, isopropyl alcohol (IPA), dimethyl sulfoxide (DMSO), acetone, and methyl tert-butyl ether (MTBE)] through negatively charged GO membranes, benchmarked against that of water. Among the solvents studied,…

Graphene sensor rapidly detects opioid metabolites in wastewater: Graphene multiplexed sensor works quicker, faster, and cheaper than previous opioid wastewater monitoring methods

The unique properties of the atom-thick sheet of carbon, known as graphene, enabled a new penny-sized, multiplexed bio-sensor that’s the first to detect opioid byproducts in wastewater, a team of researchers from Boston College, Boston University, and Giner Labs report in the latest online edition of the journal ACS Nano. The novel device is the…
