Chemists at the University of Florida have developed a technique to create highly porous materials from the ubiquitous building blocks of everyday plastics, and the end result could have applications in electronics, separations and battery manufacturing.
Lag is one of the most irritating bugs in video gaming over the internet, but rather than let it stand in the way of potentially therapeutic virtual and augmented reality (VR and AR) games, a U-M team is leading an effort to minimize it.
For years, doctors have relied on familiar vital signs — heart rate, blood pressure, temperature and oxygen levels — to monitor someone’s health. But researchers at the University of Missouri believe one key metric has been overlooked: blood viscosity, or how thick or sticky blood is as it flows through the body. And they’ve developed a breakthrough technology to monitor it non-invasively and in real time.
The first-of-its-kind device uses ultrasound waves to measure blood viscosity in real time — but the true innovation lies in its software. The system works by gently vibrating blood with a continuous sound wave — meaning it sends a steady sound wave through the blood while simultaneously sensing its response. Then, a powerful algorithm analyzes how the sound moves through the body.
A new model predicts how lightning would sweep across any airplane, including those with experimental designs. The tool generates a zoning map of the plane, showing which sections require more or less lightning protection.
LEDs are essential components in near-eye displays like virtual reality and augmented reality headsets and smart glasses, along with electronics like cameras and medical equipment. In Applied Physics Letters, researchers use AC power to drive an LED device instead of DC power, significantly reducing the complexity of fabricating nanoscale LED devices. In addition to simplifying the design, the researchers developed key improvements throughout the fabrication process and overall device performance.
