Oxidation of thiocyanate with H2O2 catalyzed by [Ru(III)(edta)(H2O)]-.

The [Ru(III)(edta)(H2O)](-) (edta(4-) = ethylenediaminetetraacetate) complex is shown to catalyze the oxidation of thiocyanate (SCN(-)) with H2O2 mimicking the action of peroxidases. The kinetics of the catalytic oxidation process was studied by using stopped-flow and rapid scan spectrophotometry as a function of [Ru(III)(edta)], [H2O2], [SCN(-)], pH (3.2-9.

Self-organized pathways to nanopatterns exploiting the instabilities of ultrathin confined bilayers.

Self-organized interfacial instabilities of an ultrathin bilayer confined between a pair of rigid surfaces is explored. The bilayers are classified based on the macroscopic dewetting behaviors of the liquid films sandwiched between a pair of confining surfaces having surface energy higher or lower than the liquid films. Linear and nonlinear analyses employing the governing equations originating from the continuum description together with molecular dynamics (MD) simulations unveil the salient spatiotemporal features of the dewetting process.

Selective oxidation of thiourea with H(2)O(2) catalyzed by [Ru(III)(edta)(H(2)O)](-): kinetic and mechanistic studies.

Reported here is the first example of a ruthenium complex, [Ru(III)(edta)(H(2)O)](-) (edta(4-) = ethylenediaminetetraacetate), that catalyzes the oxidation of thiourea (TU) in the presence of H(2)O(2). The kinetics and mechanism of this reaction were investigated in detail by using rapid-scan spectrophotometry as a function of both the hydrogen peroxide and thiourea concentrations at pH 4.9 and 25 °C.

Investigating the morphology of the proximal femur of the Indian population towards designing more suitable THR implants.

There are considerable variations in the femoral geometry of populations across different geographical locations and ethnic groups. The osteological parameters of the proximal femur are very important for the design of suitably sized prostheses of total hip replacement (THR), especially for cementless implantation. Though total hip prostheses in different sizes are available from manufacturers, best-fit implants are often unavailable for Indian patients.
