Some medicines we buy are mixtures of two or more drugs in a particular proportion. But how do manufacturers ensure that those proportions are correct? They use an analytical technique called chromatography.
You'll have seen or read in the news about how some countries are trying to develop nuclear weapons, and how some countries are trying to stop them. The element uranium lies below all of this fuss, so let's try to understand its chemistry.
If you look around, quite a lot of things in your home, your car or your school will be made of alloys. An alloy is a material made by smelting two or more metals together. Alloys have thousands of uses; indeed our lives would be very different without them. Let's have a look at some exciting alloys that will dominate our lives in the future.
We know that too much carbon dioxide in our atmosphere is causing climate change. If we increased forest cover on land, we could reabsorb some of the CO2. But did you know the best solution is actually in the oceans?
The plant kingdom is very important to us, for it provides us with food, clothing, wood and many other products. Most importantly, plants convert carbon dioxide to life. What secrets do they hold for our future?
When doing chemistry experiments at school, you might have heard your teachers telling you to use as little as possible of every chemical. Now imagine of all chemistry could be done with just one drop! That's the idea of a lab-on-a-chip.
