the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

Nanocrystalline chlorapatites (Ca10(PO4)6Cl2) doped with lanthanide ions (Eu(3+), Er(3+) and Yb(3+)) and co-doped with silver ions (Ag(+)) were synthesized by a hydrothermal synthesis route. XRD, TEM, and SAED measurements indicated that the powders are single phased and crystallize with a hexagonal structure with good dispersion. The results showed well crystallized chlorapatite grains with a ...

Optimally doped silver selenide and silver telluride exhibit linear positive magnetoresistance over decades in magnetic field and on a scale comparable to the colossal magnetoresistance compounds. We use hydrostatic pressure to smoothly alter the band structure of Ag-rich and Ag-deficient samples of semiconducting Ag(2 +/-delta)Te of fixed stoichiometry and disorder. We find that the magnetores...

Silver and aluminum-co-doped zinc oxide (SAZO) nanowires (NWs) of 1, 3, and 5 at.% were grown on sapphire substrates. Low-temperature photoluminescence (PL) was studied experimentally to investigate the p-type behavior observed by the exciton bound to a neutral acceptor (A0X). The A0X was not observed in the 1 at.% SAZO NWs by low-temperature PL because 1 at.% SAZO NWs do not have a Ag-O chemic...

In this paper, a 1.85V reduction in driving voltage of an OLED is presented by using an alkali-metal doped electron transport layer (ETL) and a silver (Ag) cathode. Such an ETL is composed of 2,9-dimethyl-4,7-diphenyl 1,10phenanthroline (BCP) doped with Cseium (Cs) to increase the conductivity of the organic material and achieve ohmic contact at the ETL/cathode interface regardless the work fun...

Herein, we demonstrate a complex-precipitation strategy for high-yield fabrication of single-crystalline Ag(3)PO(4) sub-microcubes with sharp corners, edges, and smooth surfaces, which exhibit much higher photocatalytic activities and photoelectric conversion properties than spherical Ag(3)PO(4) particles and commercial N-doped TiO(2) under visible light irradiation.

Herein, we demonstrate for the first time the fabrication of concave trisoctahedral Ag(3)PO(4) microcrystals enclosed by {221} and {332} facets based on the heteroepitaxial growth procedure, which exhibit much higher photocatalytic activities than cubic Ag(3)PO(4) and commercial N-doped TiO(2).

The studies of the bipolar resistive switching effect in thin film heterojunctions (YBa2Cu3O7-δ /Ag) and (Nd 2-x Ce x CuO4-y /Ag) have exhibited the role of oxygen as a doping element in hole- and electron-doped HTSC compounds.

The aim of this study is to analyze the use of Ag-doped activated carbon aerogels for bromide and iodide removal from drinking water and to study how the activation of Ag-doped aerogels affects their behavior. It has been observed that the carbonization treatment and activation process of Ag-doped aerogels increased the surface area value ( [Formula: see text] ), whereas the volume of meso-(V(2...
