Among the most notable nanotechnology applications is its employment in environmental remediation and biomedical applications. Nonetheless, there a need for cleaner sustainable methods preparing nanomaterials that use cheaper, more environment-friendly precursors than conventional synthesis process. The green chemistry approach preparation of nanoparticles becoming attractive as it uses non-tox...

The highly regioselective ortho-arylation of acetanilides with aromatic boronic acids in the presence of a Ru(II) complex (3 mol%), AgSbF6 (12 mol%), Cu(OTf)2 (20 mol%) and Ag2O (1.0 eq.) is described. Later, ortho-arylated acetanilides were converted into phenanthridine and carbazole derivatives by using Ph3PO and Tf2O or palladium or Cu(OTf)2 catalysts.

Muonium centres in Cu2O, Ag2O and CdO show hyperfine parameters spanning four orders of magnitude. They exemplify the three different categories of hydrogen defect centre in semiconducting and dielectric solids, with very different electronic structure and electrical activity, namely quasi-atomic (possibly deep acceptor), deep donor and shallow donor.

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 centuries, ...

Lagerstroemia speciosais commonly known as Banaba or Jarul which is used to get rid of various ailments such fever, urinary infection, decongestion, diarrhoea, mouth ulcers, astringent, diabetes mellitus, kidney diseases, abdominal pains etc. The present work, describes the green synthesis silver nanoparticles from ethanolic extract fruits L.speciosa (Ls-Ag NPs) and their analysis for antimicro...

Reaction of [Ru(OAc)2(PPh3)2] with a P-functionalized imidazolium bromide easily affords a cationic abnormal carbene Ru system. Metalation with Ag2O yields a Ru-Ag complex containing an anionic dicarbene ligand, while subsequent transmetalation with Au(tht)Cl leads to the corresponding Ru-Au system. The bimetallic complexes were characterized by single crystal X-ray diffraction and are the firs...

The chiral carbene bis[bis(R-1-phenylethyl)amino]cyclopropenylidene 2 and its dicarbene-silver complex [Ag(2)2]BF4 (3) have been isolated in good yields from the reactions of bis[bis(R-1-phenylethyl)amino]cyclopropenylium tetrafluoroborate (1)BF4 with potassium bis(trimethylsilyl)amide or with Ag2O, respectively; the molecular structures of (1)ClO4, 2 and 3 have been determined by X-ray diffrac...
