Georgia Tech study finds MD electric urban delivery trucks have cost advantages over diesel in some conditions; relative benefits depend on numerous factors

Green Car Congress

Researchers at Georgia Tech have compared medium-duty (MD) electric and diesel urban delivery trucks in terms of life-cycle energy consumption, greenhouse gas (GHG) emissions, and total cost of ownership (TCO). Is the electric truck cost-effective in comparison with the diesel truck? Credit: ACS, Lee et al. Click to enlarge.

The New, New Transistor

Cars That Think

Alan Doolittle , a professor of electrical and computer engineering at Georgia Tech. But they both pale in comparison with AlN. At Georgia Tech, Doolittle agrees that there is still room for enormous improvement by incorporating higher levels of pure AlN in future devices. The bandgap of AlN is 6.20

Life cycle study calculates Algenols algae-to-ethanol process can deliver 67% to 87% reduction in carbon footprint compared to gasoline

Green Car Congress

A team from Algenol and Georgia Tech calculated the life cycle energy and greenhouse gas emissions for three different system scenarios for this proposed ethanol production process, using process simulations and thermodynamic calculations. MJ/MJEtOH, and the net life cycle greenhouse gas emissions range from 29.8 wt % to 5 wt %.

Georgia Tech study suggests one in five materials chemistry papers may be wrong; MOFs as example

Green Car Congress

This concept is illustrated by an exhaustive analysis of a topic that has been the focus of thousands of published studies, gas adsorption in metal–organic framework (MOF) materials. … The thousands of research papers yielded just nine MOF compounds for which four or more independent studies allowed appropriate comparison of results.
