Medical supply chains are fragile in the best of times and COVID-19 will test their strength

The pipeline of pharmaceuticals is easily disrupted.| Short Read

By Mark Daskin and Emily Tucker

The COVID-19 pandemic has brought medical supply chains into the spotlight. There has been a national shortage of testing kits, and at least one drug is already unavailable because of the outbreak, though it hasn’t been publicly named.

As operations engineers who focus on how these supply chains work, we know that even in the best of times, the U.S. drug supply chain is relatively fragile. Shortages regularly occur, and the COVID-19 pandemic has the potential to further disrupt a system that patients depend on, sometimes for life or death.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
