Theoretical Study of Solid Materials for CO2 Capture Technology

Duan Y., National Energy Technology Laboratory, US

In this presentation, we will update our progress on Computational designing and screening of solid materials for CO2 capture. By combining thermodynamic database searching with ab initio thermodynamics calculations, we present a simulation scheme to [...]

Bio-inspired Solar Desalination with Zero Liquid Discharge

Finnerty C., Mi B., University of California-Berkeley, US

As traditional water resources become strained and demand continues to soar, desalination is being considered as a viable option to augment existing water supplies. Although advances in membrane technology have dramatically reduce the energy consumption [...]

Magna Imperio Systems: Innovating Solutions Through Technology

Page G., Magna Imperio Systems, US

Fresh, potable water is a sacred, yet scarce, resource that brings life to the world. The successful foundation of every community is reliant on the crucial interconnected relationship between water, food, and energy known as [...]

Integration of microfluidic chip with Loop-mediated Isothermal Amplification (LAMP) assay for rapid quantification of Enterococcus Faecalis

Han M., Kamalakshakurup G., Lee A.P., Jiang S., University of California Irvine, US

Rapid and sensitive monitoring of water quality can effectively prevent accidental human exposure to waterborne pathogens. In this project, a rapid quantification method was developed for Enterococcus faecalis, a fecal indicator bacteria (FIB), used as [...]

Electromechanical Detection of Pathogens with Self-Assembled Nucleic Acid Biosensors

Urmann K., Bahnemann J., Chikneyan Z., Kasmaee L.M., Hoffmann M.R., California Institute of Technology, US

Infectious diseases, primarily caused by enteric pathogens, remain a major cause of death, especially in remote locations of the developing world. Routine monitoring of pathogen contaminations is therefore crucial. We seek to apply quartz crystal [...]

Recovery of Desalination Brine Concentrate Using Waste Heat and Membrane Evaporation

Johnson D., University of Texas at San Antonio, US

The desalination processes produces highly concentrated brine effluent which is costly to dispose of for inland desalination facilities. The current study uses a membrane evaporation process to reduce brine volumes and recover treated brines. Membrane [...]

Exploring the Effects of Highly Conductive Carbon Fibers on Evaporation and Desalination Rates of Salt Water

Tanzim F.S., Rahman M.M., Asmatulu R., Wichita State University, US

Water scarcity is a growing problem for large regions of the world because of the insufficient sources of fresh water to meet the demands. It is estimated that 2.8 billion people around the world have [...]

Using the Membrane Biofilm Reactor to Recover Platinum Group Metals from Wastewater

Lusk B., Zhou C., Rittmann B., Tomaswick A., Precient Technologies, US

Conventional physical and chemical processes for recovery of platinum group metals (PGM) are costly and introduce contamination into the environment. Alternatively, microorganisms can biologically recover soluble PGMs as metallic nanoparticles: e.g., convert Pd(II) to Pd(0) [...]

Growth of Carbon Nanotubes on Graphene as Efficient Air–cathode for Highly H2O2 -producing Microbial Fuel Cell

Han S., Zhou C., Kansas State University, US

An efficient highly conductive three-dimensional (3D) air-cathode manufactured by growth of carbon nanotubes (CNT s) on graphene sheets (GNS) for the improvement of H2O2-producing microbial fuel cell (MFC) is reported. 3D architectured GNS-CNT s hybrid [...]

Core-shell and Immobilized Nanoscale Ferrites for H2 Generation From Thermochemical Water-splitting

Amar V., Puszynski J., Shende R., South Dakota School of Mines and Technology, US

In this study, water was used as energy carrier for H2 generation via thermochemical water-splitting process using core-shell and immobilized nanoscale ferrite materials. Core-shell ferrite nanoparticles were synthesized using pluronic P123 templating assisted sol-gel method. [...]
