GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Researchers at George Washington University led by Dr. Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes).

Study casting doubt on GHG benefits of corn stover ethanol draws sharp criticism by other researchers; Liska responds

Green Car Congress

The study led by University of Nebraska-Lincoln assistant professor Adam Liska, funded through a three-year, $500,000-grant from the US Department of Energy, used carbon dioxide measurements taken from 2001 to 2010 to validate a soil carbon model that was built using data from 36 field studies across North America.

Can We Identify a Person From Their Voice?

Cars That Think

So Stillwell went inside Atwood’s and used his phone to record his conversation with Libby and another man, Duane Maki. Voice-based recognition systems differ from old-school wiretapping and surveillance by going beyond the substance of a conversation to infer information about the speaker from the voice itself. I heard it.

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

Green Car Congress

Densities for steel springs and Li-ion batteries provide a comparison. Any system that requires conversion from mechanical energy to electrical and back again, using a generator and then a motor, will lose some of its energy in the process through friction and other processes that produce waste heat. Hill et al. Click to enlarge.
