Using everyday WiFi to help robots see and navigate better indoors

Posted: 19 May 2022 12:01 PM PDT

Engineers have developed a low cost, low power technology to help robots accurately map their way indoors, even in poor lighting and without recognizable landmarks or features. The technology uses WiFi signals, instead of light, to help the robot 'see' where it's going.

Is it topological? A new materials database has the answer

A new materials database reveals more than 90,000 known 'topological' materials with persistent electronic properties.

Human behavior is key to building a better long-term COVID forecast

Posted: 19 May 2022 11:09 AM PDT

From extreme weather to another wave of COVID-19, forecasts give decision-makers valuable time to prepare. When it comes to COVID, though, long-term forecasting is a challenge, because it involves human behavior.

New process revolutionizes microfluidic fabrication

Posted: 19 May 2022 08:53 AM PDT

Microfluidic devices use tiny spaces to manipulate very small quantities of liquids and gasses by taking advantage of the properties they exhibit at the microscale. They have demonstrated usefulness in applications from inkjet printing to chemical analysis and have great potential in personal medicine, where they can miniaturize many tests that now require a full lab, lending them the name lab-on-a-chip.

Low-cost battery-like device absorbs CO2 emissions while it charges

Posted: 19 May 2022 08:53 AM PDT

Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be reused or disposed of responsibly.

New thermal management technology for electronic devices reduces bulk while improving cooling

Posted: 19 May 2022 08:53 AM PDT

Electronic devices generate heat, and that heat must be dissipated. The high temperatures can compromise device function or even damage the devices and surroundings if it isn't. Now, a team has detailed a new cooling method that offers a host of benefits, not the least of which is space efficiency which offers a substantial increase over conventional approaches in devices' power per unit volume.

Spin keeps electrons in line in iron-based superconductor

Posted: 19 May 2022 08:53 AM PDT

Electronic nematicity, believed to be an important ingredient in high-temperature superconductivity, is primarily spin-driven in the iron-based superconductor FeSe, reveals a new study.
