We report in this paper a facile approach for the formation and electrochemical characterization of silver-silver oxide core-shell nanoparticles (NPs). Thus, thermal treatment at temperatures between 200 and 360 degrees C of Ag NP, in the gas phase or in an organic solvent, has been used to achieve the formation Ag@Ag2O NP. The evidence of formation of such a core-shell structure was obtained b...

Potential of root system of plants from wide range of families to effectively reduce membrane impermeable ferricyanide to ferrocyanide and blue coloured 2,6-dichlorophenol indophenol (DCPIP) to colourless DCPIPH2 both under non-sterile and sterile conditions, revealed prevalence of immense reducing strength at root surface. As generation of silver nanoparticles (NPs) from Ag+ involves reduction...

Plasmon-enhanced light absorption in a multicomponent Ag/Ag2O/TiO2/N3 dye-sensitized solar cell (DSSC) core−shell nanostructure is studied using a hybrid quantum mechanics/classical electrodynamics (QM/ED) methodology in which the Ag/Ag2O/TiO2 nanostructure is treated by the finite-difference time-domain method and the N3 dye is treated by real-time time-dependent density functional theory. As ...

The nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. As the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated Aeromonas and the antibacterial effect of metal nanoparticles is well known for ce...

The structures of cervinomycins A1 (1) and A2 (2), a potent anti-anaerobic and anti-mycoplasmal antibiotic were investigated by means of recent NMR techniques of O-methyl ether (3) and C,O-dimethyl ether (4) obtained by methylation of 2 with CH3I in the presence of Ag2O. The antibiotic 2 posesses a polycyclic structure involving a xanthone skeleton. The structure of 1 was confirmed to be a hydr...

Herein we propose novel photoelectrochemical fuel cells (PEFCs) by the introduction of a solid-state Ag2O/Ag cathode (here also term as photoelectrochemical battery). Due to the superior electrochemical properties of Ag2O/Ag, the maximum power density of our PEFCs can reach 0.94 mW cm(-2) upon UV illumination. Furthermore, our PEFCs have stable cycle operation and can be undertaken in a single ...

Iodine radioisotopes are released into the environment by the nuclear industry and medical research institutions using radioactive materials. The (129)I(-) anion is one of the more mobile radioactive species due to a long half-life, and it is a great challenge to design long-term management solutions for such radioactive waste. In this study, a new adsorbent structure with the potential to effi...

Well-defined nano-sunflowers were constructed by self-assembling a rod-coil amphiphile in water, and their morphologies transformed by addition of a water soluble pillar[5]arene and Ag2O were also investigated.
