BACKGROUND The demand for lactic acid has been increasing considerably because of its use as a monomer for the synthesis of polylactic acid (PLA), which is a promising and environment-friendly alternative to plastics derived from petrochemicals. Optically pure L-lactic acid is essential for polymerization of PLA. The high fermentation cost of L-lactic acid is another limitation for PLA polymers...
Pseudomonas aeruginosa strain K (PAK) bears polar pili that promote infection by at least six bacteriophages. Moreover, a recently isolated mutant of strain K (PAK/2PfS) is many times more piliated than the wild-type strain and facilitates the preparation of large amounts of pure pili for biochemical studies. The present investigation was carried out to establish the structural relatedness of P...
In this Letter, we study the spin Nernst effect (SNE) of magnons in nonlinear response regime. We derive formula for magnon current by solving Boltzmann equation and find out that it is described an extended Berry curvature dipole magnons. The SNE expected to occur various N\'eel antiferromagnets without Dzyaloshinskii-Moriya interaction. particular, honeycomb diamond lattice can be controlled ...
Nowadays, equal channel angular pressing, known as the ECAP process, is one of the most popular methods for manufacturing ultra-fine grained (UFG) materials. In this paper, Ecap process has been carried out on pure copper and 6012 aluminum alloy up to six passes by route . Principal attention was paid to the influence of parameters such as diameter, material, and the height of billet on mechani...
