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) [...]

Jatropha oil plant for biodiesel production with a biorefinery processing perspective

Vivas C.M.C., Collado D.E.A., Universidad Nacional De Ingenieria, PE

The study was aimed to support for biodiesel production of Jatropha oil. Fatty acid methyl ester (biodiesel) has been identified as alternative fuel obtained from renewable sources. Biodiesel production from Jatropa Curcas in Peru has [...]

Experimental Analysis of the Performance of Hevea brasilensis and Jatropha curcas Oils as Biodiesel

Odia O.O., Ambrose Alli University,, NG

A sure source of energy at a realistic cost for the continuation and development of the adapted life style of the inhabitants of the industrialized and the non oil producing developing world has become the [...]

Magnetic separation for high efficiency harvesting of microalgal cells

Guo C., Institute of Process Engineering, Chinese Academy of Sciences, CN

Microalgae are recognized as a promising resource to produce biofuel that is renewable and environmentally friendly energy. Microalgae harvesting remains a challenge due to small cell size, low cell density in water, and large amount [...]

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 [...]

Electrophoretic deposition an emerging technology to support fuel cell nanoelectrocatalysts

Oropeza Guzmán M., Gochi-Ponce Y., Moreno G., Tecnologico Nacional de Mexico-Instituto Tecnologico de Tijuana, MX

A new challenge of nanoelectrocatalytic materials is to find a convenient method to support them on surfaces serving as fuel cell electrodes. Traditionally, researchers have tried to prepare colloidal inks containing the nanoelectrocatalyst previously synthesized [...]

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. [...]

A novel approach towards PGM-free PEM fuel cell cathodes

Anson C., Gerken J., Preger Y., Biswas S., Root T., Stahl S., University of Wisconsin-Madison, US

One of the major obstacles preventing widespread implementation of PEM fuel cells is the current requirement for prohibitive loadings of Pt at the cathode to achieve high activity for the oxygen reduction reaction. The Pt [...]
