Toxicity of Titanium Dioxide Nanoparticles on Growth Kinetics of Activated Biomass

Das P., Bagdiya N., Kumar A., IIT Delhi, IN

The objective of this study was to study the effect of titanium dioxide (TiO2) NPs on growth kinetic parameters of aerobic sludge bacteria. TiO2 NPs (2 mg/L and 20 mg/L concentrations) were exposed to activated [...]

Enhanced Sludge Reduction Using External Bioaugmentation at a Full-Scale Municipal

Shcici R., Newbold A., In-Pipe Technology Company, Inc., US

One the biggest burdens facing municipal wastewater treatment plants are the expenses of hauling and disposing of residual biosolids, or sludge. In 2007, United States municipal wastewater treatment plants produced about 7.7 million dry tons [...]

From Rational Design to Probe Optimization: the Role of Nanoparticle Valency in Single Cancer Cell Detection in Blood via Magnetic Relaxation

Kaittanis C., Santra S., Perez J.M., University of Central Florida, US

The conjugation of targeting ligands to iron oxide nanoparticles has achieved the development of specific assays for the detection of biomedical targets through magnetic relaxation. However, limited studies investigated how the nanoparticle valency modulates the [...]

The Effect of Nanoparticles on Bacteriophage Infection

Nickel A.L., Pedulla M.L., Kasinath R.K., Montana Tech, US

We present the results of our recent findings that the introduction of apatite nanoparticles (~10 nm) in a classical phage-bacteria infection scenario increases the efficacy of the phage infection as investigated through plaque formation. The [...]

Low-power / High-temperature sensors and MEMS in SOI technology

Moreno-Hagelsieb L., Bulteel O., André N., Gerard P., Raskin J-P, Flandre D., Université catholique de Louvain / SENSOI, BE

Low-power and high-temperature sensors and MEMS designs based on bulk, SOI and IC compatible materials and processes. Target markets are in general public sensors for UV, ozone, CO, liquids presence, e.g. in mobile devices. In [...]

Isolation and Characterization of Benzene Degrading Bacteria from Gasoline Contaminated Water

Singh A., Sar P., Bennett G., Rice University, US

The BTEX (benzene, toluene, ethylbenzene, and xylene)compounds are hydrocarbon pollutants that are considered as significant threat to the health and environment. Among BTEX, benzene is of major concern, because it is soluble, mobile, toxic, carcinogenic [...]

Identification of bacterial drug resistance in blood

Kaittanis C., Nath S., Perez J.M., University of Central Florida, US

Development of antibiotic resistance by microorganisms has been on the rise in recent years. Therefore, identifying drug resistant strains and effective antibiotic agents is critical. Traditional microbiological methods assess antimicrobial susceptibility within 24 to 48 [...]

Bacterial Concentration Detection with Dielectrophoresis and Capacitive Measurement

Yoo J-H, Cha M.S., Lee J., Seoul National University, KR

The concentration of Escherichia coli (E.coli) cells in water was detected by depositing them on an array of electrodes using dielectrophoresis (DEP). Electrowetting was used to effectively concentrate the E.coli in a droplet of water [...]
