New halogen conversion-intercalation chemistry enables high-energy density aqueous Li-ion battery

Green Car Congress

A team of researchers led by a group from the University of Maryland has. developed a halogen conversion–intercalation chemistry in graphite that produces composite electrodes with a capacity of 243 mAh g -1 (for the total weight of the electrode) at an average potential of 4.2 Proposed conversion–intercalation chemistry.

New protonic ceramic fuel cell addresses power density and stability issues

Green Car Congress

Like other fuel cells, they enable direct electrochemical conversion of chemical fuels to electricity at high efficiency and with zero emissions. They are particularly attractive in comparison to other fuel cells as a consequence of the high ionic conductivity of the electrolyte at at intermediate temperatures (400–600 °C).

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

Green Car Congress

The lignin fraction is not accounted for in the main comparison between cellulosic and fossil fuels. They took another extreme position by ignoring the carbon savings associated with coproduct electricity in the conversion facility. … Liska et al. used a 5-10 year perspective. The problems with the scenario of Liska et al.

How Police Exploited the Capitol Riot’s Digital Records

Cars That Think

However, according to the legal documents, only 25 rioters appear to have been first identified through such automated image searches, mostly after comparisons with state driver’s license photos and passport applications. Not according to an ALPR photo snapped in rural Maryland at 8:44 a.m. They are how they are screwing with us.”.
