This revolution is giving us substances with properties that were once confined to the pages of science fiction books.
But these materials are more than just scientific curiosities – they are genuinely useful, to the point that as applications start to emerge they will radically change our world. Here are some amazing examples…
Together, Scientists and Spiders Create the Strongest Material Ever
For a long time, scientists
have marvelled at spiders' ability to weave silk with incredible properties.
The protein fibre that spiders spin to make their webs is stronger than almost
anything humans can make. Now, with a bit of a push from scientists, spiders
have actually created the strongest material known to humans. To read more: http://bit.ly/1LueYaQ
A Durable Plastic Made From Cellulose And Water
An Australian company has
created a material, Zeoform, that resembles plastic – and has been made into a
number of forms, including furniture and eyeglass frames – but is composed
entirely of cellulose and water. The cellulose comes either from plants such as
hemp or flax or from recycled paper or textile waste so could leave little or
no environmental footprint. To read more: http://bit.ly/1GyDekx
If Aluminium Foil and Bubble Wrap had a baby…
Afsaneh Rabiei, a professor of
mechanical and aerospace engineering at North Carolina State University, took a
thin sheet of aluminum, created small indentations in it, and added a foaming
agent in order to create bubbles within them. She then added another layer of
aluminum, bonded them together, and put the whole thing in a furnace, where the
heat changed the foamy bubbles to air pockets. The resulting material, a kind
of metallic bubble wrap, weighs 20 to 30 percent less and is 30 to 50 percent
more flexible than an untreated aluminum sheet. The material combines the best
properties of sheet metal and bubble wrap; in addition to being lighter and
stronger than sheet metal, it's much more resistant to heat and chemicals than
traditional bubble wrap, and can be used to help reinforce thin spaces in items
ranging from aircraft wings to computer cases. To read more: http://bit.ly/1BMni2E
Plastics from Potato Cells and Crab Shells
Two designers have come up with
eco-friendly alternatives to today's common plastic by using materials that
would normally be discarded. Imperial College's Jeongwon Ji extracted chitin –
"a natural polymer" – from Chinese mitten crab shells and combined it
with other ingredients to create a paste that can be moulded into a kind of
grainy rubber. Designer Ivy Wang, working with a research lab at Leeds
University, compressed potato cell walls left over from biofuel production to
develop a flexible, durable material.
The production of biodegradable
plastic is expected to grow significantly by 2020, and will ideally help
mitigate the environmental damage caused by traditional plastics. Wang's
bioplastic could put a lot of biofuel byproduct – about 2.5 tons per hectare of
potatoes – to good use.
And although prized in Asia as a delicacy, the Chinese mitten crab is considered a nuisance in the UK, so Ji's bioplastic could serve as a form of pest control. Even better, anything made from the chitin-based material will start to dissolve after being submerged in water for two weeks. Ji says, "It is about returning a kind of fragility to [objects] which usually only have a one or two year lifespan anyway." Taken from: http://bit.ly/1NaPHjn

But all of these materials will need to be tested to quantify such properties as compressional strength, flexibility, tensile strength, puncture resistance, etc. This is where a Texture Analyser can be employed to compress, bend, stretch, extrude, cut, puncture or snap a product and provide an objective analysis of the material’s physical capabilities.
