Researchers greenlight gas detection at room temperature

Russian researchers have developed a mechanism for detecting molecular hydrogen using green light to illuminate a nanocrystalline composite sensor based on zinc and indium oxides. This enables a gas sensor operating at room ...

Ultra-fast and ultra-sensitive hydrogen sensor

A KAIST team made an ultra-fast hydrogen sensor that can detect hydrogen gas levels under 1% in less than seven seconds. The sensor also can detect hundreds of parts per million levels of hydrogen gas within 60 seconds at ...

New sensor to aid in vitro fertilization

The tricky process of monitoring early-stage embryos during the in vitro fertilization process could become much easier with the development of a new fibre-optic sensor that can measure concurrently, hydrogen peroxide and ...

Glove shows its true colors

Security takes top priority in laboratories and in production. In the future, employees exposed to risks will only have to put on a glove in order to receive a toxic substance warning: This textile identifi es poisonous substances, ...

Mighty Eagle scores longest, highest flight yet

(Phys.org)—The "Mighty Eagle," a NASA robotic prototype lander, reached its highest altitude and velocity—and longest duration—on Oct. 25 when it soared to a height of more than 150 feet during a flight that lasted ...

Hydrogen alarm for remote hydrogen leak detection

Hydrogen is considered as one of the promising alternative energy sources. Nevertheless, its application as an energy carrier is complicated due to its highly explosive nature when mixed with oxygen. These dangerous situations ...

Chemists improve hydrogen sensors

A group of scientists from the Siberian Federal University (SFU, Krasnoyarsk, Russia) and the Nikolaev Institute of Inorganic Chemistry (NIIC, Novosibirsk, Russia) have combined the useful properties of metal phthalocyanines ...
