A self-cleaning electrolytic cell that converts waste streams into disinfectants

Dealing with wastewater streams in petroleum refineries and petrochemical operations is often a trying task — environmentally, economically and logistically — especially as regulations on salinity in waste streams are tightened. However, many waste streams actually contain useful components, such…

Selectively recover CO with this soft nano-porous material

Professor Susumu Kitagawa’s group at Kyoto University (Kyoto, www.sbchem.kyoto-u.ac.jp/kitagawa-lab/index-e.html) has developed a new soft nanoporous material that selectively adsorbs carbon monoxide from gas mixtures. The researchers believe their achievement will enable the separation and recycling of CO from the emissions…
