These Graphene Tattoos Are Actually Biosensors

Cars That Think

We started that work with Akinwande of UT Austin in collaboration with Roozbeh Jafari of Texas A&M University (now at MITs Lincoln Laboratory). That resistance change is converted into a readout that indicates the presence and concentration of the target molecule. You almost certainly have encountered such a device yourself.

Harvard hybrid “bionic leaf” converts solar energy to liquid fuel isopropanol

Green Car Congress

Scientists from a team spanning Harvard University’s Faculty of Arts and Sciences, Harvard Medical School and the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a scalable, integrated bioelectrochemical system that uses bacteria to convert solar energy into a liquid fuel.

MIT researchers develop oxygen permeable membrane that converts CO2 to CO

Green Car Congress

MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into carbon monoxide, and thence into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. The cells were operated in a two-electrode cell configuration. (B) Reece et al. Click to enlarge.

MIT researchers modify soil bacterium for biosynthesis of isobutanol using carbon

Green Car Congress

Researchers at MIT have modified the soil bacterium Ralstonia eutropha to produce isobutanol and 3-methyl-1-butanol (branched-chain higher alcohols). What it does is take whatever carbon is available, and stores it in the form of a polymer, which is similar in its properties to a lot of petroleum-based plastics. Earlier post.)

MIT Researchers Find That Elastic Energy Storage Systems Built With Carbon Nanotubes Could Match Li-ion Battery Energy Densities

Green Car Congress

New research by MIT scientists suggests that carbon nanotubes could be used to create elastic energy storage systems with energy densities that could be three orders of magnitude higher than those of conventional steel springs, and comparable to Li-ion batteries with potentially more durability and reliability.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

Nocera pictures small-scale systems in which rooftop solar panels would provide electricity, with any excess going to an electrolyzer to produce hydrogen, which would be stored in tanks. By doing so, he aims to imitate the process of photosynthesis, by which plants harvest sunlight and convert the energy into chemical form.
