Reinventing concrete

As the most-used building material on the planet and one of the world’s largest industrial contributors to global warming, concrete has long been a target for reinvention. Stanford scientists say replacing one of concrete’s main ingredients with volcanic rock could slash carbon emissions from manufacture of the material by nearly two-thirds.

First self-cooling fiber laser made with silica

Stanford researchers and a team of collaborators develop the first self-cooling optical fiber made of silica for laser applications and have quickly developed it into a laser amplifier – a critical step toward use in the real world.

Controlling chemistry with sculpted light

Using state-of-the-art fabrication and imaging, researchers watched the consequences of adding sculpted light to a catalyst during a chemical transformation. This work could inform more efficient – and potentially new – forms of catalysis.

Nanoparticle vaccine for COVID-19

Researchers at Stanford are working to develop a single-dose vaccine for SARS-CoV-2 that could potentially be stored at room temperature.

Future VR could employ new ultrahigh-res display

Repurposed solar panel research could be the foundation for a new ultrahigh-resolution microdisplay. The OLED display would feature brighter images with purer colors and more than 10,000 pixels per inch.

Predicting wildfires with CAT scans

Engineers at Stanford have used X-ray CT scans, more common in hospital labs, to study how wood catches fire. They’ve now turned that knowledge into a computer simulation to predict where fires will strike and spread.

Slow-light beam-steering

Researchers have fashioned ultrathin silicon nanoantennas that trap and redirect light, for applications in quantum computing, LIDAR and even the detection of viruses.
