Advancing efficiency and reliability in thermal analysis of laser powder-bed fusion

Christian Leinenbach, Rafal Wróbel, Thomas Mayer

In laser based powder-bed fusion of metals (PBF-LB/M), parts are fabricated by melting layers of powder using a high-intensity laser beam. During this process, the material is exposed to rapid cooling rates and intense thermal gradients, which are the unde ...

Atomic-scale Characterization of Strain and Gate effects on Two-dimensional Materials by Scanning Tunneling Microscopy

Jz -Yuan Juo

Strain is an inevitable phenomenon in two-dimensional (2D) material, regardless of whether the film is suspended or supported. Moreover, strain is known to alter the physical and chemical properties, such as the band gap, charge carrier effective masses, d ...

Parallel convection and E × B drifts in the TCV snowflake divertor and their effects on target heat-fluxes

Basil Duval, Holger Reimerdes, Joaquim Loizu Cisquella, Roberto Maurizio, Davide Galassi, Cedric Kar-Wai Tsui, Mirko Wensing

Parallel convection and E × B drifts act together to redistribute heat between the strike-points mechanisms is enhanced near the secondary X-point and is shown to dominate over heat in the low field side snowflake minus (LFS SF−). The cumulative heat conve ...

High-Performance n-type SnSe Thermoelectric Polycrystal Prepared by Arc-Melting

Ferenc Simon, Bence Gábor Márkus

Tin selenide (SnSe) has notable thermoelectric properties, yet stable n-type polycrystalline SnSe is difficult to synthesize. Here, polycrystalline SnSe is easily prepared by arc-melting as robust pellets, with thermoelectric properties repeatably changing ...
