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
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
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
The River Emscher was considered a "cesspool of the Ruhr": an open channel, extremely polluted with wastewater from coal mining and heavy industry and the feces of local residents. It is a sewage project of superlatives: 10 Herrenknecht-TBMs were used to build an efficient underground pipe and tunn
