Georgia Tech study finds link between sulfate, metallic particles from vehicles and adverse health impacts

Green Car Congress

Now, researchers at Georgia Institute of Technology have shown how these vehicle-emitted metals—such as copper, iron and manganese—interact with acidic sulfate-rich particles already in the air to produce an aerosol that, when inhaled, is more likely to cause oxidative stress and impact respiratory health. 6b06151.

Georgia Tech team develops highly efficient multi-phase catalyst for SOFCs and other energy storage and conversion systems

Green Car Congress

Researchers at Georgia Tech, with colleagues in China and Saudi Arabia, have developed a rationally designed, multi-phase catalyst that significantly enhances the kinetics of oxygen reduction of the state-of-the-art solid oxide fuel cell cathode. The ions meet to make water, which exits the fuel cell. 2018.02.008.

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

The study found that TCO for electric and diesel medium-duty urban delivery trucks were similar. The electric truck is relatively more cost-effective on the NYCC and when VKT demand is higher. Cost-competitiveness of the electric truck diminishes in drive cycles with higher average speeds. Credit: ACS, Lee et al.

Georgia Tech study projects potential mixed impacts of climate change policies on air quality

Green Car Congress

Results of a study by a team from Georgia Tech and their colleagues at NASA Goddard Institute for Space Studies and Northeast States for Coordinated Air Use Management show that national CO 2 emissions reductions strategies will play an important role in impacting air quality over the US. regional vs urban). —Trail et al. 5b00473.

Georgia Tech team develops simple, low-cost process for oxide nanowires; superior separators for Li-ion batteries

Green Car Congress

Researchers at Georgia Tech have developed a simple technique for producing oxide nanowires directly from bulk materials under ambient conditions without the use of catalysts or any external stimuli. The dissolution process generates hydrogen gas, which could be captured and used to help fuel the heating step. 355, Issue 6322, pp.

Georgia Tech life-cycle study finds TCO of medium-duty electric and diesel delivery trucks similar; electric life-cycle energy use and GHG lower than diesel

Green Car Congress

They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Over an array of possible conditions, the median TCO of electric trucks is 22% less than that of diesel trucks on the NYCC. However, the cost-competitiveness of the electric truck diminishes in drive cycles with higher average speed.

DOE awards $27.5M to 16 water infrastructure projects

Green Car Congress

Modern technology has the potential to reduce energy use in aging water infrastructure, particularly in wastewater treatment, which demands up to 2% of domestic electricity use each year. The US Department of Energy (DOE) is awarding $27.5 million to 16 water infrastructure projects.
