Concepts for the development of light-weight composite structures for rotor burst containment [PDF]
A set of hypotheses is established as to what variables might control the design of a weight-efficient protective device. A particular experiment for evaluating the hypotheses and materials was designed. The design and methods for the analysis of results

Electrical spin protection and manipulation via gate-locked spin-orbit fields
, 2014 The spin-orbit (SO) interaction couples electron spin and momentum via a relativistic, effective magnetic field. While conveniently facilitating coherent spin manipulation in semiconductors, the SO interaction also inherently causes spin relaxation.
