A two-laser technique is used to investigate heat spreading along individual single walled carbon nanotube (SWCNT) bundles in vacuum and air environments. A 532 nm laser focused on the center of a suspended SWCNT bundle is used as a local heat source, and a 633 nm laser is used to measure the spatial temperature profi…

An adaptive finite-element semi-smooth Newton solver for the Cahn–Hilliard model with double obstacle free energy is proposed. For this purpose, the governing system is discretized in time using a semi-implicit scheme, and the resulting time-discrete system is formulated as an optimal control problem with pointwise co…

A series of the as-burnt supported metallic catalysts (Co/SiO 2 ) were prepared by a novel surface impregnation combustion method using cobalt nitrates (noted as M) and citric acid (noted as CA), and burnt in the argon atmosphere. H 2 and CH 4 which were derived from the decomposition of the CA, acted as the reducing…

Magnetic and magnetostrictive properties of magnetic-annealed polycrystalline CoFe2O4 were investigated. The magnetic hysteresis loops showed obvious uniaxiality with an induced easy direction parallel to the annealing field. Magnetic force microscopy study revealed that the domains were fixed by magnetic annealing. T…
