Development of real-time trace hydrogen gas leakage via a novel terahertz-wave optical platform

Hydrogen gas is the smallest and lightest of all known molecules, and its colorless and odorless nature makes it easy to leak. Also, when concentrated above 4% in a confined space, it poses a risk of ignition or explosion.

Advanced full-color image sensor technology enables simultaneous energy harvesting and imaging

Organic-based optoelectronic technology is increasingly recognized as an energy-efficient solution for low-power indoor electronics and wireless IoT sensors. This is largely due to its superior flexibility and light weight compared to conventional silicon-based devices. Notably, organic photovoltaic cells (OPVs) and organic photodetectors (OPDs) are leading examples in this field.

A method for extracting iron from aluminum production waste

A team of metallurgists in Germany has developed a technique for extracting iron from aluminum production waste. In their paper published in the journal Nature, the group outlines their process and its degree of efficiency. Chenna Rao Borra, with the Indian Institute of Technology Kharagpur, has published a News and Views piece in the same journal issue outlining the work by the team on this new effort.
