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 [...]

Bromate free disinfection by high voltage pulse

Chang I-S, Hoseo University, KR

We designed and assembled high voltaged pulse generating system in our laboratory. The HVI system is consisted of power supply, high voltage generator, capacitors and impulse generator. The impulse with 10 to 20 kV/cm of [...]

Super-porous PVDF nanofibre membranes for efficient desalination of brackish water in membrane distillation applications

Mhlanga S.D., Nthunya L.N., Khumalo N.P., Verliefde A.R., University of South Africa, ZA

Water scarcity is becoming a serious problem in Southern Africa. Recent draughts have called for exploitation of alternative sources of drinking water such as brackish and seawater. Membrane distillation is an efficient desalination process that [...]

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 [...]
