Serpentine Fluidic Structures for Particle Separation

Kole A.S., Lean M.H., Seo J., Palo Alto Research Center Inc, US

The above abstract is based on a novel technique for particle separation from liquid based solely on fluidic forces on the particles. No external force or filters are used for separation. The idea is scalable [...]

Development of a Mobile Asbestos Decontamination Process

Gerdes T., Rosin A., Willert-Porada M., University of Bayreuth, DE

Within the European project “New Safe and Cost Effective Techniques Against Asbestos Risks” different methods for decontamination of asbestos in asbestos containing wastes, abbreviated as ACW from building industry were investigated. A mobile asbestos decontamination [...]

Study of model contaminants desorption from recycled PET in dry air and nitrogen atmosphere by thermogravimetric analysis

Santos A.S.F., Agnelli J.A.M., Medeiros E.S., Corradini E., Manrich S., Institute for Technological Research, BR

The polyethylene terephthalate (PET) bottle-to-bottle recycling is a good example of a successful technology that has allowed an increase of recycled plastic market. Nevertheless, the capability of all these processes to decontaminate recycled plastics into [...]

Recovery of Caustic Soda in Textile Mercerization by Combined Membrane Filtration

Yang J., Park C., Lee D., Kim S., Korea Institute of Industrial Technology(KITECH), KR

This study is intended to find the optimum operational condition for the recovery of caustic soda solution from mercerization in textile process. As parameters, the silt density index (SDI) evaluation for the application of ceramic [...]

Conjugates of Enzyme-Magnetic Nanoparticles for Bioremediation*

Qiang Y., Sharma A., Paszczynski A., Meyer D., University of Idaho, US

Enzymes are proteins that function as biocatalysts in bioremediation. One of the major concerns in environmental applications of enzymes is their short lifetime. Enzymes lose their activity due to oxidation, which results in less stability [...]

Study on non-Freon air cooling system using water refrigerant

Sugawara A., Nakamikawa S., Kageyama M., Yamazaki S., Abe N., Itou T., Tsurumaki A., Kawasaki K., Niigata University, JP

This paper aims for construction of a small, clean air cooling system using a water refrigerant and examines it experimentally. We offer a basic report for realization of the non-Freon air-cooling system using only water [...]

Development of Functionally Graded SiC-Based

Gerdes T., Willert-Porada M., University of Bayreuth, DE

Hot gas filtration using ceramic filters for diesel engine exhaust gas cleaning has gained considerable attention and growth over the last 15 years. In this contribution the development of a SiC-carbide based filter that combines [...]

Influence of His-195 on the nitrogenase FeMo-cofactor activity

Cavallotti C., Moscatelli D., Carrà S., Politecnico di Milano, IT

Mo-nitrogenase is the enzyme responsible for the conversion of atmospheric nitrogen to ammonia. Its active site is the iron-molibdenum cofactor, FeMo-co, which is composed by two incomplete cubes, Fe4S3 and MoFe3S3, connected through three bridging [...]

Effect of Surface Hydration and Interfusion of Suspended Silica Nanoparticles on Heat Transfer

Milanova D., Wu X., Kumar R., University of Central Florida, US

Nanofluid suspensions enhance thermal conductivity and the heat transfer. The authors have previously shown that the Critical Heat Flux (CHF) of NiChrome wire in a silica nanofluid can be increased by 200% compared to conventional [...]
