A research team co-led by scholars from City University of Hong Kong (CityU) has successfully morphed all-inorganic perovskites at room temperature without compromising their functional properties. Their findings demonstrate the potential of this class of semiconductors for manufacturing next-generation deformable electronics and energy systems in the future.

All-inorganic lead halide perovskites are becoming increasingly important semiconducting materials in energy conversion and optoelectronics because of their outstanding performance and enhanced environmental stability.

“However, unlike metal materials or polymers, inorganic semiconductors ar...

Small mobile robots carrying sensors could perform tasks like catching gas leaks or tracking warehouse inventory. But moving robots demands a lot of energy, and batteries, the typical power source, limit lifetime and raise environmental concerns. Researchers have explored various alternatives: affixing sensors to insects, keeping charging mats nearby, or powering the robots with lasers. Each has drawbacks: Insects roam, chargers limit range, and lasers can burn people’s eyes.

Thermometers can do a lot of things: Measure the temperature at the center of your perfectly braised chicken or tell you whether to keep your child home from school due to illness. But because of their size, traditional thermometers’ uses are still limited.

“How do you non-invasively measure a temperature...

A new generation of cloud services is on the rise. It is based on the paradigm of ‘serverless computing’. A recent article deals with the history, status and potential of serverless computing.

In cloud computing, commercial providers make computing resources available on demand to their customers over the Internet. This service is partly offered “serverless,” that is, without servers. How can that work? Computing resources without a server, isn’t that like a restaurant without a kitchen?

“The term is misleading,” says computer science Professor Samuel Kounev from Julius-Maximilians-Universität (JM...
