Effect of laser rescanning on the grain microstructure of a selective laser melted Al-Mg-Zr alloy

Christian Leinenbach

The microstructures of alloys created via Additive Manufacturing (AM) can vary substantially from those present in cast or wrought products, due to the very rapid solidification associated with AM. While numerous studies have investigated the process-micro ...

Post-Sputtering Heat Treatments of Molybdenum on Silicon Wafer

Chien-Jen Yang

This paper investigated the property evolutions of Mo thin films that were subjected to post-sputtering heat treatments from 700 degrees C to 1100 degrees C. It was found that, after annealing, the use of Si wafers eliminated crack formations found in prev ...

Thermal Transport in Crystals as a Kinetic Theory of Relaxons

Nicola Marzari, Andrea Cepellotti

Thermal conductivity in dielectric crystals is the result of the relaxation of lattice vibrations described by the phonon Boltzmann transport equation. Remarkably, an exact microscopic definition of the heat carriers and their relaxation times is still mis ...

Thermal transport in low dimensions

Andrea Cepellotti

Lattice vibrations are the microscopic mechanism responsible for a large, if not dominant, contribution to heat transport in crystalline insulators. These vibrations are described in terms of phonons, collective excitations (or quasiparticles) in the form ...

The Electronic Thermal Conductivity of Graphene

Nicola Marzari

Graphene, as a semimetal with the largest known thermal conductivity, is an ideal system to study the interplay between electronic and lattice contributions to thermal transport. While the total electrical and thermal conductivity have been extensively inv ...

Capacitive inertial sensing at high temperatures of up to 400 degrees C

Mikhail Asiatici, Göran Stemme

High-temperature-resistant inertial sensors are increasingly requested in a variety of fields such as aerospace, automotive and energy. Capacitive detection is especially suitable for sensing at high temperatures due to its low intrinsic temperature depend ...

Effect of Heat Current on Magnetization Dynamics in Magnetic Insulators and Nanostructures

Francesco Antonio Vetrò

The term "spin caloritronics" defines a novel branch of spintronics that focuses on the interplay between electron spins with heat currents. In the frame of this research area, this thesis is aimed at investigating the effect of a heat current on magnetiza ...

Heat transfer monitoring between quenched high-temperature superconducting coated conductors and liquid nitrogen

Daniele Colangelo, Bertrand Dutoit

High-temperature superconducting coated conductors (HTS-CCs) are good candidates for resistive superconducting fault current limiter (RSFCL) applications. However, the high current density they can carry and their low thermal diffusivity expose them to the ...
