Description
Indra-Mani Ghimire The Effect on Cancerous Behaviour of a Cell Due to Changes in its Mechanical Properties

If the allowance of mutated cells is increased, then they grow at a much faster rate compared to healthy surrounding cells. This research by Parag Katira et al. (Phys. Rev. Lett. 108, 028103 (2012)) shows how the change in intercellular bonding affects tumor malignancy and how these changes in the physical properties of cancer cells are mechanically responsible for uncontrolled division and migration of cancer cells.

Cameron Kopas Analysis of TC Variation in Mo-Cu Bilayer Films for Transition Edge Detectors

A series of Molybdenum‐Copper bilayers for Transition Edge Bolometers are grown and characterized to develop a reliable process to produce bilayers with a depressed superconducting transition temperature (TC) near 120 mK. These bilayers have a fixed normal metal thickness at ������ �� 1250 and a varying superconductor thickness 650 �� ������ �� 1000 . Material characterization techniques such as X‐Ray Diffraction (XRD), Rutherford Backscattering Spectroscopy (RBS), and Atomic Force Microscopy (AFM), in addition to low temperature electrical characterization techniques, are utilized to describe the films, and results are compared with a computer simulation of the Usadel proximity theory for the Mo‐Cu system. It is discovered that some Ar‐contamination is present in certain bilayers, affecting film roughness, and is determined to be the cause of deviation in bilayer TC from the theoretical simulations.
