Design of a Resistance-Based High Temperature Liquid Metal Flow Meter
… at these extreme conditions. As a part of the Atomic Simulation & Energy (ASE) Research Group here at MIT, this research seeks to develop a flow meter able to measure the 1200 ºC pumped liquid tin in their methane pyrolysis system. This paper presents a summary of a literature review of methods …

Micromechanics of deformation and stress evolution in thin films and patterned lines on substrates
… of such phenomena, an experimental 2-D atomic simulation was developed, via an extension of the classical soap bubble raft, to simulate elastic contact and defect nucleation at low loads. Dislocation nucleation inside crystals of low defect density, ostensibly requiring stresses on the …

Atomic structures of carbon nanomaterials studied by coherent electron diffraction
… probes. This thesis reports an investigation of atomic structures of various carbon nanoforms including graphene, CNT and nanodiamond using electron diffraction techniques. The major findings are summarized below. In a multi-walled carbon nanotube (MWCNT), quantitative electron diffraction …

Simulations of Indentation at Continuum and Atomic levels
… on relations between deformations at the atomic level and stresses and strains defined at the continuum level. These are then used to compare stress and strain distributions in mechanical tests performed on atomic systems and their equivalent continuum structures. Whereas averaged stresses …
