Everything about a spider's web - from the material it
is spun from, to the glue that binds it together - is
an engineering masterpiece. Built in seconds, each strand
in the web is a highly engineered polymer fibre, 10-times
stronger than steel. Like spiders, we use a wide range
of polymer fibres to build the world around us. This lecture
explores how chemistry is trying to mimic the natural
world and construct a more ambitious and efficient man-made
one.
The trainer is a miracle of modern science. The average
pair lasts just six months, but in that time, they will
have run 3,000 miles, absorbed 400 litres of sweat and
withstood 400 tonnes of impact. How they survive this
battering is down to some miraculous chemistry that lurks
beneath their flashy skin - a hidden world of impact cushioning
gel, moisture absorbing insoles, and breathable foot-hugging
coatings. So tune in and explore the chemistry that propels
us around the planet.
Ten years ago mobile phones were the size of bricks, as
heavy as a bag of sugar and the property of only the very
rich. Now they are everywhere, smaller than a credit card
and lighter than a Mars bar. But what shrunk the mobile
phone, and how come we all have one? Join Tony as he explores
the chemistry that connects people and asks what does
the electronic chemistry have in store for us?
The humble plaster is one of the simplest steps on the
road to repairing the damaged body, yet it is a marvel
of chemical engineering - a miniature hospital, dispensing
everything from antibiotics to aftercare. But how does
the plaster stick, and how does it allow the wound to
breathe, while at the same time keep it dry? Our knowledge
of the chemistry of our bodies now extends far beyond
plasters. Now we have soap, toothpaste & shampoo that
make us smell nice, our parents look younger and our teeth
last as long as we do. Check out the lecture to discover
more!
Creating ice cream that will re-freeze time after time
but still remains as tasty as the day it was made, is
a major culinary conundrum. New ways of conjuring up this
faultless cuisine may come from the most unlikely places
- serving up the perfect ice cream may depend on understanding
how Arctic fishes stop themselves from freezing in their
icy homes. But if we can mimic this seemingly magical
feat, could we do far more than make the perfect raspberry
ripple? Could we cryogenically freeze your granny and
then defrost her back to her radiant self again?
