Background I would imagine your first question is ‘Why is enamel resistant to vibrations?’ And that is a good question. Nature has had millions and millions of years to engineer a material for animal teeth that can handle the pressures, stresses and friction of eating/chewing. Biology came up with enamel. Hard ceramic columns are surrounded…… Continue reading Enamel – cooler than you think!
I’m pretty sure you know stainless steel. It’s likely when you last ate with cutlery you handled stainless steel. So what makes this steel stainless? Chromium is key! First of all, we must understand what steel is. Steel is an alloy of iron and carbon. It is a metal that is cheap and has a…… Continue reading What makes Stainless Steel ‘Stainless’?
Gold: A Material History – why is gold so precious? It has been used as currency for thousands of years.
They sound like something straight of science fiction – and in a way they are.

First of all, a crystal is just something made of a repeating structure…… Continue reading What are Time Crystals?
I was scrolling through social media when I came across this Instagram post. I found this very interesting and thought I would try to summarise it here for you too read. Background These ‘whiskers’are long, thin, microscopic, crystalline structures that can sprout from metals like tin, zinc, silver and cadmium. They can stretch multiple millimetres up…… Continue reading Metals Can Grow Whiskers!?
I noticed recently that I picked up a follow from Milos Djukic, a very interesting name may i add, and I took a look at his blog. It seems like this guy knows his stuff about hydrogen embrittlement mechanisms of metallic materials. I wanted to use this post to try and process this and explain, in a…… Continue reading Hydrogen Embrittlement from a Novice…
As we know the climate is changing. Humans need to change to renewable sources of energy (energy sources that are sustainable and do not harm the environment) Check out this visual representation of Earths temperatures. Solar panels harness the energy of the sun. Seems clever right? Plants have been doing it for billions of years. How…… Continue reading How Solar Panels Work and Why We Should Use Them!
