Scientists demonstrate electricity producing capabilities of 3D paper-based microbial fuel cells

Scientists at Ames-based Iowa State University have demonstrated that three-dimensional microbial fuel cells (or MFC) could channel liquids through themselves via capillary action, thus eliminating the need for any kind of external power. Appearing in this month's issue of the TECHNOLOGY journal, the research opens up a range of possibilities when it comes to producing electric…



Tin-oxide nanoparticles can reduce the charging time of Li-ion batteries from hours to mere minutes

In October, we talked about an advanced Li-ion battery design that replaces graphite with the cheaper titanium dioxide gel. This time around, scientists at the Purdue University have developed a new alternative for graphite, in the form of a material made from tin-oxide nanoparticles. According to their research (which is published in Advanced Energy Materials),…
