Facile tandem Suzuki coupling/transfer hydrogenation reaction with a bis-heteroscorpionate Pd–Ru complex

Abstract: Design and synthesis of the bis(pyrazol-1-yl)methane based bis-heteroscorpionate Pd–Ru complex results in efficient tandem Suzuki coupling/transfer hydrogenation reaction with a broad range of substrate reactivity.

Dispersion Relation Preserving Combined Compact Difference Schemes for Flow Problems

Abstract: In this work, we have proposed two new combined compact difference (CCD) schemes for the solution of Navier---Stokes equations. These spatial discretization schemes have not only high spectral resolution for obtaining first and second derivative terms, but also have improved dispersion relation preserving properties when the fourth-order four-stage Runge---Kutta scheme is used for time integration. Out of the two proposed CCD schemes, the first scheme has upwind stencil, while the second scheme has a central stencil. Important numerical properties of these schemes have been analyzed and their effectiveness have been shown by solving the model wave equations, as well as Navier---Stokes equations. Results show that the upwind CCD scheme is suitable for high accuracy large eddy simulation of transitional and turbulent flowfields.

Abrasive Wear Behaviour of TiB 2 Reinforced In-Situ Synthesized Magnesium RZ5 Alloy based Metal Matrix Composites

Abstract: Abrasive wear behaviour of TiB2 reinforced in-situ magnesium RZ5 alloy-based metal matrix composites was investigated using a pin-on-disc wear testing apparatus. The in-situ RZ5/TiB2 composite was synthesized through the self-propagating high-temperature synthesis route. The microstructure of the composite revealed a near-uniform distribution of TiB2 in magnesium matrix. The abrasive wear behaviour on the base RZ5 alloy and TiB2 reinforced composites were investigated in terms of weight loss and co-efficient of friction. The effect of varying applied load (10–30 N), sliding distance (1000–3000 m), and wt% of TiB2 content on abrasive wear properties were analysed. The results indicated a higher wear loss of the materials with increase in the applied load and sliding distance. Co-efficient of friction decreased with increase in the applied load but increased with increase in sliding distance. The morphology of the worn surface under different test conditions was analysed in terms of delamination, wear groove, oxide, and wear debris formation using field emission scanning electron microscope. Large flaky shape wear debris was noticed when the load applied is 30 N whereas equiaxed wear debris was noticed when the applied load is 10 N. Increase in sliding distance increased the contact temperature led to the formation of the oxide layer on the contact surface.
