Scientists from the University of Pennsylvania (Penn) and the University of Michigan have created the world's smallest autonomous and programmable robots. Each measuring about 200 micrometers wide – ...

Abstract: As technology develops, researchers are focusing more on using robots to improve human lives. These devices are difficult to use and require electricity to run. There are power outages all ...

Perovskite-silicon tandem solar cells are considered a key technology for photovoltaics. Because of their design, they use sunlight more efficiently than conventional silicon cells. While the upper ...

Perovskites are promising materials for solar cells. A layer of dipolar molecules at the perovskite surface improves the efficiency of these devices. Read the paper: All-perovskite tandem solar cells ...

IISc physicists discovered that Ramanujan’s classic π-formulas arise naturally in modern theories describing critical phenomena and black holes. The connection suggests his early mathematics may have ...
