Synthesis, DFT Calculations, DNA Interaction, and Antimicrobial Studies of Some Mixed Ligand Complexes of Oxalic Acid and Schiff Base Trimethoprim with Various Metal Ions

Mixed ligand metal complexes are synthesized from oxalic acid with Schiff base, and the Schiff base was obtained from trimethoprim and acetylacetone.The synthesized complexes were of the type [M(L1)(L2)], where the metal, M, is Ni(II), Cu(II), Cr(III), and Zn(II), L1 corresponds to the trimethoprim ((Z)-4-((4-amino-5-(3,4,5-trimethoxybenzyl)pyrimid

Applicability of Convex and Concave Shaped Surface Texturing to Improve Damping Performance of Mechanical Tensioner for Timing Chain of Internal Combustion Engine

The present study describes an improvement of damping performance of a mechanical tensioner driven by friction force at the power spring interface, used for the timing chain system for an internal combustion engine.The mechanical tensioner consists of a power spring subjected to face-to-face contact with a reciprocal motion and a leaf spring to app
