A hydrogen sensor that works at room temperature

Researchers at TU Delft have developed a highly sensitive and versatile hydrogen sensor that works at room temperature. The sensor is made of a thin layer of a material called tungsten trioxide.

Team develops new way to study nanoparticles

Scientists at Chalmers University of Technology have developed a new way to study nanoparticles one at a time, and have discovered that individual particles that may seem identical in fact can have very different properties. ...

Lava dots: Scientists make hollow, soft-shelled quantum dots

(Phys.org)—Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way of using molten ...

Size matters in nanocrystals' ability to adsorb, release gases

More efficient catalytic converters on autos, improved batteries and more sensitive gas sensors are some of the potential benefits of a new system that can directly measure the manner in which nanocrystals adsorb and release ...

Researchers develop extremely sensitive hydrogen sensor

Hydrogen is a highly promising energy carrier. But it can also be dangerous, as it is combustible and difficult to detect. Using hydrogen safely requires sensors that can detect even the smallest of leaks. Researchers from ...

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 ...

Fast, easy way to make hydrogen nanosensors found by scientists

A team of Northern Illinois University scientists, with a major role played by NIU Ph.D. students, has discovered a new, convenient and inexpensive way to make high performance hydrogen sensors using palladium nanowires.

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 ...
