The use of carbon nanoparticles is shown for the detection and identification of different Shiga toxin-producing Escherichia coli virulence factors (vt1, vt2, eae and ehxA) and a 16S control (specific for E. coli) based ...

[EN] Carbon fiber is most often used in high-level competition vehicles for its physical and mechanical properties. The goal of this work is to design and manufacture a motorcycle frame for regional championships, spreading ...

[EN] The corrosion behaviour and the wear ranking of biomedical high carbon (HC) and low carbon (LC) CoCrMo alloys sliding against an alumina ball in four different simulated body fluids [NaCl and phosphate buffered solutions ...

[EN] Chitosan is a N-containing biopolymer that can form high-quality films on glass, quartz, metals and other hydrophilic surfaces. Pyrolysis of chitosan films under argon at 800 degrees C and under inert atmosphere gives ...

[EN] The Fenton reaction is widely used for remediation of waste water and for the degradation of organic pollutants in water. Currently, there is considerable interest to convert the classical Fenton reaction, which ...

[EN] Fe or Co nanoparticles (NPs) and two nanoparticulate Fe-Co alloys having different Fe/Co atomic ratio with average particle size ranging from 10.9 to 26.5 nm embedded in turbostratic graphitic carbon matrix have been ...

[EN] The project consists of the welding of carbon steel F-1140 with a percentage of carbon of 0.4%, temperable by heating and rapid cooling, and the variation of its characteristics when welding with MAG welding and ...

Single- and double-wall carbon nanotubes (CNTs) having dimethylanilino (DMA) units covalently attached to the external graphene wall have been prepared by the reaction of the dimethylaminophenylnitronium ion with the ...

Ruthenium nanoparticles supported on titania are over three times more active than conventional ruthenium on carbon for the hydrogenation of lactic acid. This superior catalytic activity can be due to a combined action of ...
