A sonochemical process has been developed for the insertion of tin nanoparticles into mesoporous carbon, giving a product which was used as a building block for the anode of a rechargeable Li battery; the electrode could deliver a reversible capacity of 400 mAh gr(-1)(C + Sn) at 100% cycling efficiency, which is higher than that of graphite electrodes.

Niobium and antimony doped tin oxide loose-tubes decorated with Pt nanoparticles present outstanding mass activity and stability, exceeding those of a reference carbon-based electrocatalyst. Physico-chemical characterisation and in particular X-ray photoelectron spectroscopy demonstrate that this observation can be ascribed to the strong metal-support interaction promoting electroactivity and P...

Improvement of polyvinyl alcohol stability against ultraviolet (UV) illumination is achieved by introducing cadmium sulfide (CdS) nanoparticles into the polymeric matrix. Enhancement of stability is analyzed by optical characterization methods. UV protection is achieved by diminishing the probability of photo-activated formation of defects in polymer. The sources of polymer protection are the l...

zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...

in  this paper  thin  films of  tin sulfide (sns) were deposited on  the glass substrates using spray pyrolysis method with the substrate temperatures in the range of 400–600℃, keeping the other deposition parameters constant. in  this work  the characteristic of sns  thin  films  investigated. the xrd pattern and optical transmittance of thin films also are discussed. with the change in concen...

The studies on removal of Vanadium were conducted using Granulated Activated Carbon (GAC) in combination with Chelating agents. Ethylene di-amine Tetra Acetic Acid (EDTA) and Nitrilo Tri Acetic Acid (NTA) at 25oC. The adsorption Efficiency was studied in the pH range of 2-8. The results reveals that Langmuir and Freundlich isotherms are followed during adsorption process with the chelating agen...

Inflammatory diseases such as acute lung injury and ischaemic tissue injury are caused by the adhesion of a type of white blood cell--polymorphonuclear neutrophils--to the lining of the circulatory system or vascular endothelium and unchecked neutrophil transmigration. Nanoparticle-mediated targeting of activated neutrophils on vascular endothelial cells at the site of injury may be a useful me...

Size-controlled cadmium sulfide nanoparticles were successfully synthesized by immobilized Rhodobacter sphaeroides in the study. The dynamic process that Cd(2+) was transported from solution into cell by living R. sphaeroides was characterized by transmission electron microscopy (TEM). Culture time, as an important physiological parameter for R. sphaeroides growth, could significantly control t...
