We investigate the thermal conductivity in the armchair and zigzag MoS2 nanoribbons, by combining the non-equilibrium Green's function approach and the first-principles method. A strong orientation dependence is observed in the thermal conductivity. Particularly, the thermal conductivity for the armchair MoS2 nanoribbon is about 673.6 Wm(-1) K(-1) in the armchair nanoribbon, and 841.1 Wm(-1) K(...

In specially constructed thermal diffusion columns separations between the isotopic mixtures 1 2 C 1 8 0/ 1 2 C 1 6 0 and 1 4 C 1 6 0/ 1 2 C 1 6 0 were measured at average temperatures ranging from T = 260 ° K to T = 465 °K . At temperatures above 320 ° K 1 4C 1 60 concentrates more strongly in the cold region than 1 2 C , 8 0 . Below this temperature the opposite effect is taking place: the th...

aacel9a [β-1,4-endoglucanase, (e.c:3.2.1.4)], was immobilized onto glutaraldehyde activated chitosan macrosphere by covalent attachment. the properties of the immobilized aacel9a were investigated by determining the optimum ph and optimum temperature for activity, thermal stability, and kinetic parameters. the immobilization process shifted the enzyme’s optimum temperature from 65 °c for the fr...

the term nanofluids was first coined by sir stephen choi in 1995 at argonne national laboratory ,u.s.a .since the discovery, nanofluid have been explored as heat transfer fluids. nanofluids increased the thermal conductivity of existing coolants (water, ethylene glycol) by a magnitude of hundred times which made them attractive for miniaturization of electronic devices .from 1995 till 2008 nano...
