An integral approach for water treatment and the use of water-energy interdependency network

Lin Y., Zhou Z., Pan S-Y, Snyder S., Argonne National Laboratory, US

Freshwater stress and scarcity is one of the most challenging emerging issues due to climate change, rapid population growth, urbanization, and improved standards of living. Desalination of seawater or impaired water, such as brackish water [...]

Controlled Release Polymers for Remediation of Contaminated Groundwater

Carpenter A., Gause C., Luster-Teasley S., AxNano, US

The EPA estimates that one out of every four Americans lives within three miles of a hazardous waste site. Over 450,000 brownfield sites are awaiting remediation with 1,280 sites on the National Priorities List (NPL). [...]

GO-based filtration membrane for removal of Endocrine Disrupting Compounds (EDCs) from water

Paneri A., Moghaddam S., University of Florida, US

We live in a world where synthetic chemicals have become a part of our day-to-day life. As a result, some of these pollutants enter our water streams and food chain and interfere with the normal [...]

Analysis of Permeance vs. Support Porosity for Thin Film Composite Membranes

Karampelas I.H., Zhu L., Jia W., Yavari M., Lin H., Furlani E.P., University at Buffalo (SUNY), US

Membranes are an important technology for industrial gas separation and seawater desalination and emerging applications such as CO2 capture. The key to the steady growth of membrane applications is high performance thin film composite (TFC) [...]

A Novel Technology for Removal/Recovery of Toxic Heavy Metal

Acey R.A., Jordaan G.R., Nguyen H., Nguyen P.H., Nguyen H., Nguyen P.H., MGP Biotechnologies,LLC, US

We have developed a novel technology for the removal/recovery of heavy metal from aqueous and organic solvents. The patented technology is based on a low molecular weight protein known as metallothionein (MT). The protein has [...]

A self-powered glucose monitor

Kulkarni T., Mburu N., Slaughter G., University of Maryland Baltimore County, US

Glucose substrates are successfully harnessed to generate electricity in a membraneless biofuel cell with a mesh-network of carbon nanotubes pyroquinoline quinone glucose dehydrogenase-modified anode and a laccase-modified cathode. Using glucose as a substrate, this glucose-oxygen [...]

Nitrogen-modified biomass-derived porous carbon for electric double layer capacitors application

Wang K., Gu Z., Fan Q., South Dakota State University, US

This work shows that N-doped carbon can be derived from pyrrole modified biomass-lignin. Simultaneous chemical and physical activation using potassium hydroxide during the heat treatment can effectively create porous N-doped carbon. The activated carbon possesses [...]
