Fantastic Plastic to help water and gas industries

CSIRO research leader Dr Anita Hill discusses research into new plastics that have the potential to mitigate greenhouse gas emissions and help purify water.

Nanotechnology and the iPod
Source: EPSRC
This movie uses interviews with people on the street and contributions from members of staff at both the University of Sheffield and Sheffield Hallam University, to explore some of the science behind the iPod's capacity to store large amounts of music and other data in such a small space. You can get songs and videos off the internet, store and play them whenever you want, but what enables it to do this?

Nanotechnology and the running shoe
Source: EPSRC
Running shoes are designed to absorb energy, to make them comfortable and protect your feet. To do this they have to be soft and squishy, but if you walked on a soft material it would flatten out, getting deader and deader as you went through the day. To stop this, we need to add hard bits to the formulation. These prevent the shape squishing too far, and allow it to rebound after each step. As a result, the running shoe stays in shape. The nanotechnology comes in because the soft and the hard bits we use are the size of polymer molecules.

Polymer Membrane

CSIRO, through the Water for a Healthy Country Flagship, in partnership with Hanyang University in Korea and the University of Texas, has developed a new plastic membrane that mimics pores found in plants and has the potential to mitigate greenhouse gas emissions and help purify water. This animation demonstrates the process

Smart surfaces switch properties
Source: MIT
Professor Robert Langer and colleagues at the Institute for Soldier Nanotechnologies are working on a unique design of a 'smart surface' that can reversibly switch properties in response to an external stimulus. The new switchable surface essentially consists of a forest of molecules only a nanometer tall, engineered to stand at a precise distance from each other. When a positive electrical potential is applied, the top bends down to reveal another surface. Reverse the electrical potential, and the molecules straighten to their full height. The work paves the way for systems that could, for example, release or absorb cells and chemicals from surfaces on demand. Future work will include developing surfaces that have different switchable properties as well as tailoring the proof-of-concept system for different applications.

Space elevator

The Space Elevator is a thin ribbon, with a cross-section area roughly half that of a pencil, extending from a ship-borne anchor to a counterweight well beyond geo-synchronous orbit. Electric vehicles, called climbers, ascend the ribbon using electricity generated by solar panels and a ground based booster light beam.

Super Cloth

Using nanotechnology, Cornell scientists created a fabric that can detect biohazards like E. coli and other pathogens. Super Cloth is a segment from Partners Video Magazine's latest episode, The Science of Small.
