A polynucleating oxygen donor ligand based on condensation of p-chlorophenylstibonic acid (ArSbO(3)H(2)) and t-butylphosphonic acid is reported. [(SbAr)(2)O(HO(3)P(t)Bu)(6)] contains two antimony centres, bridged by an oxide and two hydrogen phosphonates. Reaction with copper acetate under solvothermal conditions produces four new polymetallic copper complexes. With pyridine used as a base the ...

Interdiffusion studies on high-T, superconducting YBasCu,O,_s thin films with thicknes~s in the range of 2000-3000 A, on a Si(ll1) substrate with a buffer layer have been performed. The buffer layer consists of a 400 A thick epitaxial Nisi, layer, covered with 1200 A of polycrystalline 210,. YBa,Cu,O,_s films were prepared using laser ablation. The YBa,Cu,O,_, films on the Si/NiSi,/ZrOs substra...

Extracts prepared from seeds of Manilkara zapota, Anona squamosa, and Tamarindus indica were screened for their antibacterial activity by disc diffusion and broth dilution methods. Acetone and methanol extracts of T. indica seeds were found active against both gram-positive and gram-negative organisms. MIC values of potent extracts against susceptible organisms ranged from 53-380 μg/mL. Methano...

The production of new generation of wood preservatives (without addition of a co-biocide) in combination with an exchange of wood poles on identical sites with high fungal inoculum, has resulted in an increase of premature failures of wood utility poles in the last decades. Wood destroying basidiomycetes inhabiting sites where poles have been installed, have developed resistance against wood pr...

Abstract The perovskites Nd 1-x Ce x Co 1-y Cu y O 3 ( = 0–0.05, 0–0.1) have been synthesized using PVP-assisted sol–gel method and applied for soot oxidation reactions. XRD technique reveals the formation of orthorhombic phase with crystal volume around ~ 214 Å size 25–40 nm. interconnected nanoparticles hollow spherical network morphology particles are observed samples NdCoO (NC1) 0.98 0.02 0...

The Kondo resonance of Co adatoms on the Cu(100) and Cu(111) surfaces has been studied by scanning tunneling spectroscopy. We demonstrate the scaling of the Kondo temperature T(K) with the host electron density at the magnetic impurity. The quantitative analysis of the tunneling spectra reveals that the Kondo resonance is dominated by the Cu bulk electrons. While at the Cu(100) surface both tun...
