Joule heating and negative dielectrophoresis, caused by AC electric fields in a microchannel, have been employed for cloud point extraction of phospholipid as a model of membrane-associated biomolecules.

Context. Many thermally emitting, isolated neutron stars have magnetic fields that are larger than 1013 G. A realistic cooling model that includes the presence of high magnetic fields should be reconsidered. Aims. We investigate the effects of an anisotropic temperature distribution and Joule heating on the cooling of magnetized neutron stars. Methods. The 2D heat transfer equation with anisotr...

The spin injection and accumulation in metallic lateral spin valves with transparent interfaces are studied using dc injection current. Unlike ac-based techniques, this allows the investigation of the effects of the direction and magnitude of the injected current. We find that the spin accumulation is reversed by changing the direction of the injected current, whereas its magnitude does not cha...

A three dimensional finite element model calculation was constructed, which includes different submodels, all as a function of temperature, using an iterative approach, to investigate permalloy artificial spin ice network with square geometry on thermal annealing while applying voltage pulse. Magnetization is also included into the simulation equation defining change magnetization temperature. ...

Abstract: Presence of externally applied electric field can cause the flow field in the micron and submicron channels; this generated flow field is called electroosmotic. In this type of flow field, the presence of the external electric field causes the extra generated heat in the domain that may affect the performance of the system (Joule heating effect). In the present study, an analytical ap...

A proximity-effect thermometer measures the temperature dependent critical supercurrent in a long superconductor normal metal superconductor (SNS) Josephson junction. Typically, the transition from the superconducting to the normal state is detected by monitoring the appearance of a voltage across the junction. We describe a new approach to detect the transition based on the temperature increas...

Joule heating generated by the electrical current in capillary electrophoresis leads to a temperature gradient along the separation channel and consequently affects the separation quality. We describe a method of reducing the Joule heating effect by incorporating photonic crystal fiber into a micro capillary electrophoresis chip. The photonic crystal fiber consists of a bundle of extremely narr...

We show that the main mechanism for the dc voltage or dc current induced insulator-metal transition in vanadium dioxide VO(2) is due to local Joule heating and not a purely electronic effect. This "tour de force" experiment was accomplished by using the fluorescence spectra of rare-earth doped micron sized particles as local temperature sensors. As the insulator-metal transition is induced by a...

In this paper, we studied the effects of thermal radiation, Joule heating and viscous dissipation on magnetohydrodynamics (MHD) Marangoni convection boundary layer over a flat surface. We also investigated the influence of suction and injection on the boundary layer. Numerical results were obtained using the shooting method along with the Runge-Kutta-Fehlberg method. The influences of the inter...
