After a fire is extinguished, the atmosphere control system will filter the air to remove particulates and toxic substances. Next, we'll look at the technologies that help the space shuttle navigate, change direction and communicate from space. Space Shuttle Positioning, Communication and Naviga...

Natural gas hydrofracking in the US is one of the more polarizing topics. The chemicals in fracking fluid are of such low concentration that it does not matter if it gets in the local water supplies. But they mix concentrated versions of these incredibly toxic chemicals into the fracking fluid...
What the Frack? How Weak Industrial Disclosure Rules Prevent Public Understanding of Chemical Practices and Toxic PoliticsHydraulic fracturing, known colloquially as "fracking," makes use of chemically-formulated fluid that is forced down a gas well at great pressure to fracture underground rock ...
Geothermal plants can release hydrogen sulphide, a gas that smells like rotten eggs. Finally, some geothermal fluids contain low levels of toxic materials which need to be disposed of. Geothermal and TWI Due to TWI’s expertise incoatings and material properties, in addition to our extensivework...
They produce no smell or air pollution, unlike friction brakes, which can release toxic "particulates" (microscopic bits of dust and metallic fragments) into the environment. All this makes them much more attractive than noisy friction brakes that need regular inspection and routinely wear out. It...
There is, however, a sweet spot in which hairs, bent at just the right angle, with an elasticity neither too soft nor rigid, can affect the fluid flowing through them. The researchers found that such angled hairs straighten when fluid is flowing against them. In this configuration, the hair...
This natural gas boom is largely thanks to hydraulic fracturing, commonly known asfracking. This extraction process combines chemicals, often toxic ones, with large amounts of water andsand at high pressureto shatter the earth and rocks. Fracking is a controversial issue because of the number of...
As we mentioned on the last page, there can be some toxic chemicals in brake cleaner which means that you not only have to make sure you're in a well-ventilated area with the proper protective wear on, but you also need ensure that the car is protected as well. Those chemicals can ha...
