We can make the steel of tomorrow without the fossil fuels of yesteryear
A trio of Swedish firms are developing a means of producing high-quality steel without releasing so much carbon dioxide -- and Volvo is already using it to build mining equipment.
Researchers create 'rubber-band electronics' material, capable of stretching up to 200 percent (video)
One of the major issues with embedded medical devices is the lack of flexibility in existing electronics. Fortunately, researchers at the McCormick School of Engineering at Northwestern University have developed a new material that can create electronic components capable of stretching to 200 percent of their original size. One of the major obstacles was how stretchable electronics with solid metal parts suffered substantial drops in conductivity but this solution involves a pliable three-dimensional structure made from polymers with 'pores'. These are then filled with liquid metal which can adjust to substantial size and shape changes, all while maintaining strong conductivity. We've embedded a very brief video of the new stretchable material going up against existing solutions -- it's right after the break.
