In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...
The connection between microscopic material properties and qubit coherence are not well understood despite practical evidence that material imperfections present an obstacle to applications of superconducting qubits. In a ...
Stress and strain, applied in just the right manner, can sometimes produce amazing results.

Soft electronics are increasingly in demand for diverse applications, but they lack rigid enclosures and are therefore susceptible to premature disposal after electronic applications. It is therefore necessary to create soft ...
Nanofluidic platforms can offer tunable material transport for biosensing, chemical detection and filtration. Research in the past had achieved elective and controlled ion transport based on electrical, optical and chemical ...
Shantanu Chakrabartty's laboratory has been working to create sensors that can run on the least amount of energy. His lab has been so successful at building smaller and more efficient sensors, that they've run into a roadblock ...
