Scientists turn a hydrogen molecule into a quantum sensor

Physicists at the University of California, Irvine have demonstrated the use of a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope, a technique that can measure the chemical ...

Sensor that detects hydrogen peroxide in living plant cells

Hydrogen peroxide (H2O2) is commonly known as a bleaching and disinfecting agent. However, it is also constantly produced in living cells. Often as a byproduct of biological processes, sometimes intentionally, for example ...

Thumb-sized device quickly 'sniffs out' bad breath

No one wants bad breath—not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious ...

New optical hydrogen sensors eliminate risk of sparking

Hydrogen as a clean, renewable alternative to fossil fuels is part of a sustainable-energy future, and very much already here. However, lingering concerns about flammability have limited widespread use of hydrogen as a power ...

Researchers develop a versatile hydrogen sensor

Hydrogen is playing an increasingly important role in the transition to a completely sustainable economy. It is already being used on a large scale in industry, but it is also being used more often for sustainable energy ...

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 ...
