Massachusetts Institute of Technology scientists have identified a new way to boost yeast tolerance to ethanol by simply altering the composition of the medium in which the yeast are grown. Yeasts are commonly used to remake sugar, corn starch and other plant materials into biofuels such as ethanol, but high concentrations of ethanol can be […]

Rice University scientists combined graphene quantum dots drawn from common anthracite coal with graphene oxide, nitrogen and boron into a catalyst for fuel cells that outperforms the expensive rare earth platinum. In a fuel cell application the graphene quantum dots grab onto graphene platelets like barnacles attach themselves to the hull of a boat. The […]

Scientists at the Center for Research in Advanced Materials (CIMAV) have developed a device that fits inside a pair of shoes that harvests the energy made available when someone walks. This energy is then stored in AAA or watch batteries. The team designed a pill-shaped cylinder adapted to a shoe in order to store the […]
