Capturing light: New ergonomic photodetector for the trillion-sensor era (28/09/2021)

The world is heading towards a trillion-sensor economy where billions of devices using multiple sensors will be connected under the umbrella of Internet-of-things. An important part of this economy is constituted of light/photo sensors, which are tiny semiconductor-based electronic components that detect light and convert them to electrical signals. Light sensors can be found everywhere around us, from household electronic gadgets and health-care equipment to optical communication systems and automobiles.

New way to simulate hydrogen storage efficiency of materials (28/09/2021)

Hydrogen energy has the potential to be a key measure to meet the United Nations net zero emissions target, but its industrial use has been hindered by the difficulty in its storage and handling. Hydrogen becomes a gas at a very low temperature (-252°C), which makes its storage at room temperature challenging. The interaction between hydrogen and its storage material is simply too weak to persist at room temperature. This makes the design of storage materials crucial to achieving the goal of bringing hydrogen energy into daily use.

Optical chip protects quantum technology from errors (28/09/2021)

In today's digital infrastructure, the data-bits we use to send and process information can either be 0 or 1. Being able to correct possible errors that may occur in computations using these bits is a vital part of information processing and communication systems. But a quantum computer uses quantum bits, which can be a kind of mixture of 0 and 1, known as quantum super-position. This mixture is vital to their power—but it makes error correction far more complicated.

Artificial intelligence may be set to reveal climate-change tipping points (28/09/2021)

Researchers are developing artificial intelligence that could assess climate change tipping points. The deep learning algorithm could act as an early warning system against runaway climate change.
