Hardware developments to improve image quality for cryoEM of biological specimens
… the use of two hardware developments, liquid helium cooling of the specimen during imaging and chromatic aberration (*C<sub>c</sub>*) correction, to improve the quality of cryoEM images, the latter in particular for thick specimens. I demonstrate that *C<sub>c</sub>* correction can be used to …

Room-Temperature Terahertz Detection Based on Graphene and Plasmonic Antenna Arrays
… are more sensitive but require liquid helium cooling. In this thesis, two types of room-temperature high-responsivity graphene-based THz detectors are presented, relying on the unique properties of graphene and the function of plasmonic antenna arrays which boost the interaction between …

USING COMPUTATIONAL METHODS TO OPTIMIZE HIGH HEAT FLUX COMPONENT THERMAL PERFORMANCE IN MAGNETIC CONFINEMENT FUSION REACTOR RESEARCH
… and analyzing test sections supporting a helium flow loop assembled at Oak Ridge National Laboratory to analyze heat transfer enhancement for systems such as blanket and divertor components. This initial phase uses STAR-CCM+ to study a base set of literature-supported helium-cooled ribbed …
