Hot vibrating gases under the electron spotlight

Natural gas is used in refineries as the basis for products like acetylene. The efficiency of gaseous reactions depends on the dynamics of the molecules—their rotation, vibration and translation (directional movement). ...

Mind the nanogap: Fast and sensitive oxygen gas sensors

Oxygen (O2) is an essential gas not only for us and most other lifeforms, but also for many industrial processes, biomedicine, and environmental monitoring applications. Given the importance of O2 and other gases, many researchers ...

Prototype generators emit much less carbon monoxide

Portable electric generators retrofitted with off-the-shelf hardware by the University of Alabama (UA) emitted significantly lower levels of carbon monoxide (CO) exhaust, according to the results* of tests conducted by the ...

Apple rejoins green tech program after spat

Apple said Friday it was rejoining a program to certify its products as environmentally friendly after a controversy that could have dented sales of its popular gadgets.

The physics of extracting gas from shale formations

Extracting gas from new sources is vital in order to supplement dwindling conventional supplies. Shale reservoirs host gas trapped in the pores of mudstone, which consists of a mixture of silt mineral particles ranging from ...

Recreating outer space plasma systems in the lab

Thermodynamics provides insight into the internal energy of a system and the energy interaction with its surroundings. This relies on the local thermal equilibrium of a system. The application of classical thermodynamics ...

Determining the parameters for transmission electron microscopy

While the phones in our pockets may be perfect for taking photos of our pets, taking good images of catalysts and other materials is far more complex, especially when you bring in scanning transmission electron microscopy ...

Researchers building foundation for heat-tolerant electronics

Case Western Reserve University is leading an international investigation of a finicky alternative to silicon-based electronics and its use in high temperatures or under radiation that would render traditional components ...
