Svante Littmarck is the CEO of the COMSOL group. He co-founded COMSOL in 1986. He holds a M.Sc. in Applied Mathematics from the Royal Institute of Technology in Stockholm. In 2004 he received an honorary doctoral degree from the Royal Institute of Technology. Mehr lesen
The oxidation behavior of metallic nanoparticles is investigated in respect to material parameters like Mott potential, defects on the microstructure and oxide volume increase per ionic defect. An emphasis is laid on magnetic nanoparticles where the degree of oxidation can be measured ... Mehr lesen
Flip-chip interconnection technologies have been tested through the use of a test chip with embedded single-bump daisy chains. The Flip-Chip technologies are selected among Au bump Thermocompression (TC) with and without Nonconductive Adhesives (NCA) underfiller, anisotropic conductive ... Mehr lesen
A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... Mehr lesen
In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... Mehr lesen
Spent fuel transportation casks are required to meet among others (test conditions), the regulatory thermal test conditions in order to demonstrate their ability to withstand specified accidental fire conditions during transport. This paper describes the transient thermal analysis ... Mehr lesen
The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in ... Mehr lesen
Capacitor Discharge Sintering (CDS) is an ultrafast Electric Current Assisted Sintering method (u-ECAS) suited for electrically conductive powders. It is characterized by relatively short processing times (milliseconds range) and much lower sintering temperatures than the melting point ... Mehr lesen
The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... Mehr lesen
