Influence of His-195 on the nitrogenase FeMo-cofactor activity
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 [...]
Development of Functionally Graded SiC-Based
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 [...]
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 [...]
Conjugates of Enzyme-Magnetic Nanoparticles for Bioremediation*
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 [...]
Recovery of Caustic Soda in Textile Mercerization by Combined Membrane Filtration
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 [...]
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 [...]
Development of a Mobile Asbestos Decontamination Process
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 [...]
Sorption of Ethylbenzene, Toluene and Xylene onto Crumb Rubber from Aqueous Solutions
Crumb rubber is composed of a complex mixture of elastomers (polyisoprene, polybutadiene and styrene-butadiene) and carbon black, as reinforcing agent, among other compounds. The contents of carbon black and the presence of the elastomeric matrix [...]
Growth and Some Enzymatic Responses of E. coli to Photocatalytic TiO2
The effects of photocatalytic nano-TiO2 on the survival or die-off of E. coli (e.g. TK2) were investigated under ambient conditions. Experimentally, a 28-h E. coli culture was exposed to photocatalytic nano-TiO2 at various concentrations, e.g., [...]
Novel FD SOI Devices Structure for Low Standby Power Applications
In this paper, fully depleted (FD) SOI devices with S/D extension shift and high-k offset spacer were investigated in detail. The results show that the S/D extension shift can decrease Ioff significantly to reduce standby [...]
Solar-Blind Dual-Band UV/IR Photodetectors Integrated on a Single Chip
Currently used flame detectors that are composed of discrete UV and IR solid-state components are bulky, sustain temperatures only below 125°C, and are not capable of detecting a multi-band optical signal with high spatial resolution. [...]
