Carbon nanotubes, or CNT, are being used to make products stronger, lighter, faster, and more efficient. But are they safe? A growing body of research is raising concerns over the hazards presented by some forms of the material. As ever though, the risk to health depends on who is exposed to what
Carbon dioxide is a product of one of the most important chemical reactions in the world: combustion. Like water, the bonds in carbon dioxide are POLAR COVALENT, making the carbon atom delta positive and the oxygens delta negative. Although, unlike water, carbon dioxide is not a polar molecule ov
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
Learn the basics about carbon neutral and biofuels, as a part of environmental chemistry. Coal, oil, natural gas, shale gas and gas from fracking are fossil fuels formed hundreds of millions of years ago from living things that got trapped by layers of sediment before they had time to decompose. H
In this video segment adapted from NOVA, hear physicist and energy expert Amory Lovins explain how to make more efficient cars by making them lighter and more aerodynamic. Explore how the use of carbon fiber can reduce weight without reducing size or durability, and learn about some manufacturing ch
Watch part 2 of the videos on the Carbon Cycle, as a part of environmental chemistry. Mankind has had an influence on the carbon cycle. The carbon dioxide released during respiration is cycled naturally. Same is the case if we burn wood and agricultural waste – even biogas given off from food we t
Watch the first part of our Carbon Cycle videos, as part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large polymer molecules from small molecules. Protein comes from joinin
It is very important that ramp and apron workers realize and remember just how complex their workplace is. This film is intended to help ensure that accidents or damage on the apron can be prevented wherever possible.
