A hybrid approach of colloidal lithography and metalorganic chemical vapour deposition (MOCVD) has been used to fabricate ZnO nanowire bundles and nanoholes by using a silver metalorganic precursor as the growth catalyst.

In the present project, fructose-stabilized gold, silver and gold–silver bimetallic colloids have been synthesized by electrochemical reduction of HAuCl4·3H2O (Au precursor) AgNO3 (Ag precursor), employing atmospheric pressure microplasma technique. X-Ray Diffraction patterns particles exhibit (111), (200) (220) planes identical to gold NPs depicting FCC structures. The decrease in peak intensi...

age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. the cells had greater affinity for diamine silver compared to methenamin...

In this work, an effective method was developed to fabricate bendable circuits on a polydimethylsiloxane (PDMS) surface by inkjet printing semi-wrapped structures. It is demonstrated that the precured PDMS liquid film could influence the depositing morphology of coalesced silver precursor inkjet droplets. Accordingly, continuous and uniform lines with a semi-wrapped structure were fabricated on...

Gas-phase silver nanoparticles were coated with silicon dioxide (SiO2) by photoinduced chemical vapor deposition (photo-CVD). Silver nanoparticles, produced by inert gas condensation, and a SiO2 precursor, tetraethylorthosilicate (TEOS), were exposed to vacuum ultraviolet (VUV) radiation at atmospheric pressure and varying temperatures. The VUV photons dissociate the TEOS precursor, initiating ...

In this research, the fabrication of MCM-41 mesoporous material nanofibers by an electrospinning technique was performed. The MCM-41 nanofibers (MCM-41 NFs) as a novel host on the incorporation of silver has been studied in [Ag(NH3)2]NO3 precursor solution through the heat-treatment process. The formation of silve...

This work reports an environmentally benign method for the in situ preparation of silver nanoparticles (AgNPs) in paper using microwave irradiation. Through thermal evaporation, microwave heating with an excess of glucose relative to the silver ion precursor yields nanoparticles on the surface of cellulose fibers within three minutes. Paper sheets were characterized by electron microscopy, UV-V...

Design and fabrication of noble metal nanocrystals have attracted much attention due to their wide applications in catalysis, optical detection and biomedicine. However, it still remains a challenge to scale-up the production in a high-quality, low-cost and eco-friendly way. Here we show that single crystalline silver nanobelts grow abundantly on the surface of biomass-derived monolithic activa...

The concept of shape-controlled synthesis is discussed by investigating the growth mechanisms for silver nanocubes, nanowires, and nanospheres produced through a polymer-mediated polyol process. Experimental parameters, such as the concentration of AgNO(3) (the precursor to silver), the molar ratio between poly(vinylpyrrolidone) (PVP, the capping agent) and AgNO(3), and the strength of chemical...
