ICL researchers develop new membrane-based system for cheap, efficiently made biofuels

Green Car Congress

In contrast to water, the extractant does not form a heterogeneous azeotrope with n-butanol, and the overall energy consumption of for n-butanol production is 3.9 This is achieved by combining a spray-coated thin-film composite membrane with 2-ethyl-1-hexanol as an extractant.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. Oil spill clean-up is an expensive and complicated process that often harms marine life and further damages the environment. Skimmers don’t work in rough waters or with thin layers of oil. —Vikas Nandwana.

BNL Researchers develop low-cost, efficient, non-noble metal electrocatalyst to produce hydrogen from water

Green Car Congress

James Muckerman at the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have developed a new class of high-activity, low-cost, non-noble metal electrocatalyst that generates hydrogen gas from water. The result becomes this well-balanced Goldilocks compound—just right. —James Muckerman.

Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. This is achieved by introducing a Lewis acid layer (for example, Cr 2 O 3 ) on transition metal oxide catalysts to dynamically split water molecules and capture hydroxyl anions.

An abundant and inexpensive water-splitting photocatalyst with low toxicity active in visible light

Green Car Congress

Researchers at Japan’s National Institute for Materials Science (NIMS) have discovered a new photocatalyst, Sn 3 O 4 , which facilitates the production of hydrogen fuel from water, using sunlight as an energy source. Sn 3 O 4 has great potential as an abundant, cheap, and environmentally benign solar-energy conversion catalyst.

Cheap Sensors for Smarter Farmers

Cars That Think

Depending on factors such as how the sun hits the ground, the amount of water or the fertilizer needed could vary patch by patch. With the new, cheap sensors, farmers will be able to collect data on their farms without worrying about the variability. Each wireless sensor node is used for non-contact water stress detection in plants.
