What is a metal?

...chemistry terms used in this course that you may not be familiar with, so we have defined them to help your study of this course. An element is a substance made up of only one type of basic building block and each element is made up of building blocks, called atoms. You might already know that an atom itself comprises many other smaller particles (e.g. electrons, protons,...

Humphry Davy, laughing gas and the era of self-experimentation

...chemistry and subjective experience – to create a groundbreaking hybrid, a poetic science that could encompass both the chemical causes of the experience and its philosophical consequences. By the end of 1800 his reputation had spread through Britain’s scientific community and beyond, and he was already preparing to leave Bristol for a post at the Royal Institution,...

Biofuels

...chemistry. But they are pretty far away. I hope we will see more geothermal, wind of course is ready and I think we need to see a lot of wind. One of the challenges will be to also develop better storage so I hope we will see some battery improvements that would allow us to you know store energy better. I So I'm picking up that biofuels is part of the answer and the...

...chemistry of water. The two hydrogen atoms are not exactly opposite each other, but are instead at an angle. Video 1 shows a three-dimensional representation of water molecules, with the atoms in a water molecule (two hydrogen atoms and one oxygen atom) represented by spheres. Watch this video now.

...chemistry, sometimes it just requires a slightly different approach and I think it requires a lot of creative thinking to overturn people’s attitudes, which are not borne of… I don’t think they’re borne of boredom, I think they’re borne of just simply not knowing what to do how to do it. Can nature conservation borrow ideas from other sectors? Well, one of the...

...chemistry that we expect from the maps we have. Orbital images help us a lot in knowing what might be ahead. Looking from the ground will add all the details to that picture. I am excited about the area, especially from a mineralogical point of view. We call the next unit ahead ‘sulfate bearing unit’ on our maps. That sounds like alteration minerals and, most...
