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. They are not totally understood… Their existence was only suggested in 2012.Only recently have researchers (from Maryland/Havard University) managed to make them, as you can read here. 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…
Knowledge of materials have shaped the path of human history. In the past many discoveries have been accidental but have had huge consequences. One development, that had huge implications, was the use of Bronze alloys. First of all what is Bronze? You may think of this as a colour. Bronze is actually an alloy of predominantly copper(~85%)…… Continue reading A very brief story of copper alloys
