The thermal conductivity of superconducting MgB 2 was studied in both the superconducting and normal state region. The latter is almost equally determined by the electronic-and the lattice thermal conductivity. In the superconducting state, however, the lattice thermal conductivity is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Ba...

PURPOSE To assess by means of computer simulations whether the heat sink effect inside a large vessel (portal vein) could protect the vessel wall from thermal damage close to an internally cooled electrode during radiofrequency (RF)-assisted resection. METHODS First,in vivo experiments were conducted to validate the computational model by comparing the experimental and computational thermal l...

We study a quantum system composed of three interacting qubits, each coupled to different thermal reservoir. show how engineer it build device analogous an electronic bipolar transistor. outline the interaction among qubits plays crucial role for appearance effect, also linking characteristics system-bath interactions that govern decoherence and dissipation mechanisms system. By comparison with...

Isotope effects on heat conduction and convection have been known for decades. However, whether thermal radiation can be isotopically engineered remains an open question. Here, we predict over 3-orders-of-magnitude variation of radiative flow with varying isotopic compositions polar dielectrics at room temperature. We reveal this as isotope mass effect which induce phonon line shift broadening ...

Liquid paraffin as a coolant fluid can be  applied in electronic devices as a result to its suitable capabilities such as electrical insulating, high heat capacity, chemical and thermal stability, and high boiling point. However, the poor thermal conductivity of paraffin has been confined its thermal cooling application. Addition of high conductor nanoparticles to paraffin can fix this drawback...
