Flexible electronic sensors based on paper have the potential to cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper.
In their two day annual meeting, held in Utrecht, The Netherlands, from 22-24 October 2014, 35 partners from 12 EU countries presented their exiting results of the first 12 months of the SUN - Sustainable Nanotechnologies Project.
Physicists have discovered a new manganese compound that is produced by tension in the crystal structure of terbium manganese oxide. The technique they used to create this new material could open the way to new nanoscale circuits.
As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it.
Scientists are aware that these agricultural wastes have significantly high silica content in a molecular state, similar to hydrocarbons. Armed with that knowledge, researchers have discovered that these agricultural waste products can be economically transformed into silicon carbide consisting of nanostructures and nanorods in various polytypes.
Internal bleeding is a leading cause of death on the battlefield, but a new, injectable material could buy wounded soldiers the time they need to survive by preventing blood loss from serious internal injuries.
Theoretically, iron pyrite could do the job, but when it works at all, the conversion efficiency remains frustratingly low. Now, a research team explains why that is, in a discovery that suggests how improvements in this promising material could lead to inexpensive yet efficient solar cells.
