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.

This study considers the progress of our previous for hydrogen generation depends on highly ordered metal oxide/plasmonic materials. reports preparation Ag2O-Ag/Au Al2O3 template (Ag2O-Ag/Au/Al2O3) photocatalytic sewage water splitting and H2 gas production. Ni imprinting, followed by two-step anodization procedures, prepare template. Ag2O-Ag Au materials are prepared inside using electrochemic...

In this study, silver oxide nanoparticles (Ag2O-NPs) were synthesized from nitrate using green amaranth leaf extract as a reducing agent. The degradation of caffeine and inactivation Escherichia coli (E. coli) by Ag2O-NPs was studied under compact fluorescent lamp illumination irradiation. Apart that, the antibacterial antioxidant activities also examined. Synthesized shaped like monodispersed ...

Hybrid multi-functional nanomaterials comprising two or more disparate materials have become a powerful approach to obtain advanced materials for environmental remediation applications. In this work, an Ag-Ag2O/TiO2@polypyrrole (Ag/TiO2@PPy) heterojunction has been synthesized by assembling a self-stabilized Ag-Ag2O (p type) semiconductor (denoted as Ag) and polypyrrole (π-conjugated polymer) o...

The objective of this work was to prepare and characterize a new and highly efficient modified membrane by in situ interfacial polymerization on porous polysulfone supports. The process used m-phenylenediamine and trimesoyl chloride in hexane, incorporating silver oxide Ag2O nanoparticles of varied concentrations from 0.001 to 0.1 wt%. Ag2O nanoparticles were prepared at different sizes varying...

Figure S1a,b show the optical and field emission scanning electron microscope (FESEM) images of the RuO2 NMs. The nanomaterials exhibited nanosheet morphology with length >1 μm and the width <100 nm. The X-ray diffraction (XRD) spectrum (Figure S1c) showed the prominent peaks at the diffraction angle (2θ) 28.00, 34.93, 39.64 and 54.00, representing (110), (101), (200) and (211) set of latti...
