Materials Masterclass: Strong and fragile glass formers explained!
Lots of pharmaceuticals can form glasses if cooled rapidly, but some are described as strong glass formers and others as fragile glass formers. But what do these terms mean? Where do they come from? And should I worry whether my material is a strong or fragile glass former? All of these questions and more* will be answered in this video!
*Actually there's no more. That's yer lot :)

How can the same material have different glass transition temperatures?!
Просмотров 191Месяц назад
How can one compound appear to have different Tg values? That's crazy! Surely there should be only one, true value? Well, you'd think so but in reality the way the glass is made AND the way Tg is measured will all affect the Tg value determined. But why? What is it about formation that changes Tg? And why do different analytical techniques give different Tg values? All will become clear in this...
Materials masterclass: Plasticisers in amorphous solids (glasses)
Просмотров 223Месяц назад
Ever wondered why amorphous pharmaceuticals are so unstable when there's water around? It's because water is an excellent plasticiser, and speeds up the rate at which amorphous materials relax, ultimately leading to crystallisation. Plasticisers are also added to all sorts of plastics and polymers, to change their mechanical properties and feel to the touch. But what are they? And how do they w...
DSC Masterclass: How to interpret Glass Transitions
Просмотров 273Месяц назад
I can't tell you how good our students seem to be at *seeing* glass transitions in their materials when run in a DSC. But are they actually glass transitions or just desperation on the part of the students? Mmm... Here we look at how glass transitions appear in a DSC, why they should be seen as a step change in the baseline and why they are sometimes seen as an exothermic peak. By exploring why...
Understanding the science behind relaxation of amorphous solids
Просмотров 213Месяц назад
Amorphous materials are tricky! For one thing, they are always changing. If you leave candy floss (or cotton candy) in the open air it will have shrunk to almost nothing in just a few minutes. Or if you're a racoon and you put your cotton candy in water you'll be a sad and confused racoon (ruclips.net/video/rfbb4yRBH64/видео.html). Not good! But why? What is it that amorphous glasses do that me...
Revealed: Why Amorphous Solids DON'T Melt!
Просмотров 4162 месяца назад
Amorphous solids are just that - solid. Well, below their glass transition temperature anyway. When heated they turn to liquids, so just like crystalline solids they melt, right? No! In fact an amorphous material CANNOT melt. So what do they do? Well, that's what we'll look at in this video.

Unlocking the Mystery of Glass Transition Temperatures
Просмотров 3982 месяца назад
The glass transition temperature (or Tg) is one of those mysterious concepts that seems very hard to understand - not any more! In this video we look at the glass transition in easy-to-understand terms; what it is and what happens to a material to make a glass. The concept is highlighted with diagrams, video and an indecent amount of indomethacin. There are some related videos you might also wa...

Moles are one of those concepts that ALWAYS confuses students of chemistry, yet if you understand what they are you'll be able to do all kinds of calculations and conversions. Oh, and pass your exams! Who wouldn't want to do that? So in this video we'll look at what a mole is, why we need moles in the first place and how we use moles in calculations - in fact, we'll work through six example que...
Demystifying frequency distributions
Просмотров 2318 месяцев назад
Nearly all data in nature are distributed in some way and understanding frequency distributions is absolutely key to being able to compare data sets and perform hypothesis testing (as we'll look at in a later video). So here we look at frequency distributions - in particular the Normal distribution - using our trusty example - Nurofen tablets... We'll look at what the Normal distribution is, ho...

Understanding standard error of the mean
Просмотров 2958 месяцев назад
Data are interpreted through mean (accuracy) and standard deviation (precision) as we have seen in previous videos. But there is one more parameter that we can use to estimate precision; standard error, more commonly called standard error of the mean. It's a quick and easy value to determine and is a very useful parameter, so here we look at how it's defined and how to calculate it. Oh, and I g...
