Beyond batteries: Storing power in a sheet of paper
Beyond batteries: Storing power in a sheet of paper Researchers turn everyday paper into resilient, rechargeable energy storage device Peer-Reviewed Publication Rensselaer Polytechnic Institute image: A sample of the new nanocomposite paper developed by researchers at Rensselaer Polytechnic Institute. Infused with carbon nanotubes, the paper can be used to create ultra-thin, flexible batteries and
Why are lions not as big as elephants?
Carnivores are some of the widest ranging terrestrial mammals for their size, and this affects their energy intake and needs. This difference is also played out in the different hunting strategies of small and large carnivores. Smaller species less than 15-20 kg in weight specialize on very small vertebrates and invertebrates, which weigh a small fraction of their own weight, whereas larger specie
A quantum (computer) step
A quantum (computer) step Study shows it's feasible to read data stored as nuclear 'spins' Peer-Reviewed Publication University of Utah image: University of Utah physicist Christoph Boehme works with equipment that he uses to show it it feasible for a superfast quantum computer of the future to read data that is stored in the form of magnetic "spins" of phosphorus atoms. view more Credit: John Lup
