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
Relationships are hard. It takes a lot of work and a lot of practice to get things right in a relationship. Even though they’re all different, there are still some universal no no’s that we should be aware of. Here are a few common habits that can harm any relationship. Disclaimer: If you can rela
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
What make advanced materials potentially harmful? In part 5 of this Risk Bites series on advanced materials, we explore what characteristics of materials affect their safety, and increase their potential risks to human health. Risk Bites was created by Andrew Maynard. This week's video was prod
Learn the basics about Testing for hydrogen, oxygen, carbon dioxide and chlorine. Why do we need to test these particular gases? Find out more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind The Fuse S
Nail polish hardeners that work with UV radiation are used in many nail salons. They are also available for use at home. But the UV-A radiation used is basically carcinogenic. We were asked how harmful the devices can be to the skin: In the video, we explain how UV-A radiation works, what to conside
Everyone now has one at home and we also have Wi-Fi more and more often when we're on the road. We were asked if that was actually still good. Or is that perhaps dangerous after all? Spoiler: No, health hazards do not emanate from the Wi-Fi networks, we explain why in the video. Original: "Federal
5G is the upcoming standard in mobile communication. What do we know about the health effects? Original: "Federal Office for Radiation Protection" Original: German. All translations in this video have been done by the alugha AI.
