This work reports on a novel nonenzymatic amperometric glucose sensor based on the ordered mesoporous carbon (OMC). Amperometric method was used to evaluate the electrocatalytic activity of the OMC modified electrode toward nonenzymatic glucose in alkaline media in presence and absence of chloride ions. The results indicated that OMC showed electrocatalytic activity for the oxidation of glucose...

Bile peptone broth and alkaline peptone water (pH 8.5) were examined as enrichment media for the isolation of Plesiomonas shigelloides from stools, with salmonella-shigella agar as the isolation medium. After 423 parallel examinations in two different experiments, bile peptone broth enrichment for 24 h was observed to be six times more effective (P less than 0.01) than direct plating alone on s...

Uniform, size-controlled, and optimized crystalline Ru NPs on carbon supporter by FBR-ALD for the improved HOR performance in alkaline media.

Carbon nanotubes are of great interest due to their high surface area and rich edge sites, which are favorable for wide applications. Here, a simple and efficient routine is presented by decoration of multi-wall carbon nanotube (MWCNT) with nickel oxide (NiO) nanoparticles.The morphologies of NiO-MWCNT  were  investigated  by  using scanning  electron  microscope  (SEM)  and energydispersive X-...

CoCrFeNiTax (x = 0, 1) coatings were prepared on the surface of TC4 by laser-cladding to improve corrosive wear property and extend its service life in media, ultimately aiming performance. The effects Ta addition phase constituent microstructure first investigated. Given wide application media (even undergoing friction), covered with was especially focused two (neutral alkaline). results showe...

In this study, porous zinc oxide nano-flakes were successfully synthesized by anodization method on zinc substrate in a 0.025 M NaOH and 0.05 M NH4Cl solution with the voltage of 10 V at room temperature. The field emission scanning electron microscopy’s (FESEM) images show the structural evolution during 90 min of the anodization process. They also demonstrate the dependency of growth of ZnO f...

The recently developed protocol for the absolute determination of the various polysulfide species based by 1H NMR was applied to monitor the amount of such ions in alkaline media produced at different conditions. The thermal stability of each individual polysulfide species was also evaluated in temperature ranges representative of a typical alkaline pulping process. Overall, the species, S1, S2...
