Christopher B. Murray shares his excitement, thoughts, and knowledge on quantum dots, a nanoparticle that just earned his Ph.D. advisor the Nobel Prize in Chemistry.
A suit of armor for cancer-fighting cells
3d render of T cells attacking cancer cells

Chimeric antigen receptor T cell (CAR T) therapy has delivered promising results, transforming the fight against various forms of cancer, but for many, the therapy comes with severe and potentially lethal side effects. Now, a research team led by Michael Mitchell of the School of Engineering and Applied Science has found a solution that could help CAR T therapies reach their full potential while minimizing severe side effects.

Leading the charge: new research unveils the future of energy-efficent power delivery
Digital illustration of lithium ions passing through two-dimensional channels within a crystal structure

The rapid movement of lithium ions along the 2D vertical channels in the T-Niobium oxide (T-Nb2O5) thin film results in unique property changes and a chase transition. The blue and purple polyhedra show T-Nb2O5 lattices, without and with lithium, respectively. The bright green spheres represent lithium ions.
