Uncorking champagne bottle produces supersonic shock waves

Opening a bottle of champagne traditionally marks the beginning of a festive celebration. Following the fun pop of the cork, a fizz of bubbles releases into the air, and finally, there is the pleasant tingle on the tongue.

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 ...

More efficient separation of methane and CO2

To make natural gas and biogas suitable for use, the methane has to be separated from the CO2. This involves the use of membranes, filters that stop the methane and allow the CO2 to pass through. Researchers at KU Leuven ...

Researchers develop Gas Gain Stabilization System for TRT ATLAS

The Transition Radiation Tracker (TRT) is part of the ATLAS inner detector at the CERN LHC.The basic tracker element is named "straw." Straw is a simple gas detector, a long, thin (~ 1 m in length) drift tube filled with ...

Researchers apply diamond coatings to iron and steel tools

Scientists from Tomsk Polytechnic University (TPU) have created coverings for next-generation cutting tools that are not only durable, but also suitable for the treatment of most materials. They have developed a technology ...

'Electronic nose' determines food freshness

A new device analyzes gas mixtures using semiconductor sensors. Odor is determined by a combination of existing gases in the atmosphere. Researchers have found that the conductivity of a semiconductor probe changes during ...

Limestone powder enhances performance of 'green' concrete

Adding limestone powder to "green" concrete mixtures—those containing substantial amounts of fly ash, a byproduct of coal-burning power plants—can significantly improve performance, report researchers from the National ...

Producing hydrogen from water with carbon / charcoal powder

In the latest advance in efforts to find an inexpensive way to make hydrogen from ordinary water—one of the keys to the much-discussed "hydrogen economy"—scientists are reporting that powder from high-grade charcoal and ...

Nanomaterial to help reduce CO2 emissions

University of Adelaide researchers have developed a new nanomaterial that could help reduce carbon dioxide emissions from coal-fired power stations.
