Researchers at Korea University develop high-performance textile-based electrodes for watersplitting

Green Car Congress

Researchers at Korea University have developed high-performance, textile-based electrodes for watersplitting (WSE); the non-noblemetal-based electrodes can generate a large amount of hydrogen with low overpotentials and high operational stability. 2 and a low cell voltage of 1.70 doi: 10.1039/d2ee01510b.

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

A study of emissions from gasoline direct injection (GDI) vehicles in an urban near-road environment in Toronto over a wide range of weather conditions (February 2014 to January 2015) found that—other than for NO x and CO—the GDI engines had elevated emissions compared to the Toronto fleet.

Researchers in China, US develop binder-free high-silicon-content flexible anode for Li-ion batteries

Green Car Congress

A team from Zhejiang A&F University, Huazhong University of Science and Technology (HUST), and Stanford University have developed a binder-free, flexible, and free-standing electrode comprising an unprecedented 92% silicon content for Li-ion batteries. The structure shows an ultrahigh electrode-specific capacity of 2700 mAh g ?1

Study finds lead from leaded gasoline persists in London air despite ‘90s ban

Green Car Congress

The researchers say this highlights the long-term persistence of contaminants introduced by human activities in the environment. In the 1980s, annual average airborne lead concentrations in central London dropped from 500-600 ng/m 3 of air to around 300 ng/m 3 , before dropping further to around 20 ng/m 3 in 2000.

KAUST team devises electrically-driven membrane process for seawater lithium mining

Green Car Congress

Researchers at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have developed a continuous electrically-driven membrane process which successfully enriches lithium from seawater samples of the Red Sea by 43,000 times (i.e., to 9013.43 ppm) with a nominal Li/Mg selectivity >45 million. doi: 10.1039/D1EE00354B.
