Researchers exploring new water-based method for testing met-coal samples

Roben Jig coal washing process could more accurately evaluate coal quality A new method of testing exploration coal samples could not only be less harmful to the environment, it could also result in a more accurate assessment of how economically viable coal projects are. The Canadian Carbonization Research Association (CCRA) and Geoscience BC will this […]

Just a few grains of the newly synthesized material could allow us to stay underwater without scuba tanks … or yoga (Photo: Shutterstock). View gallery (2 images) Using specially synthesized crystalline materials, scientists from the University of Southern Denmark have created a substance that is able to absorb and store oxygen in such high concentrations […]

WaterDrop puts water savings in the bag

Recently, showers like the Nebia and the Hamwell’s e-Shower have launched to help us save water when showering. The WaterDrop foldable watering can, however, takes a much simpler approach. It is designed to collect the average 3.5 l (0.8 gal) of water we waste waiting for the shower to warm up. Designed by Spanish startup […]

Water treatment technologies powerful enough to reverse drought in the desert

A glass half full: These water treatment technologies are so powerful they can fight drought in the desert Water scarcity has again become a hot topic as California and Texas lurch into their fourth year of drought and Brazil’s Sao Paulo may start rationing water in 2015. But in some parts of the world the […]

Oxygen absorbing material may allow us to breathe underwater

Using specially synthesized crystalline materials, scientists from the University of Southern Denmark have created a substance that is able to absorb and store oxygen in such high concentrations that just one bucketful is enough to remove all of the oxygen in a room. The substance is also able to release the stored oxygen in a […]

SPRAYING IRON IN ANTARCTICA CREATES GREEN GARDENS OF ALGAE TO COMBAT CLIMATE CHANGE

MAN MADE ALGAE IN ANTARCTICA BENEFITS CLIMATE CHANGE The seas around Antarctica can, at times, resemble a garden. Large-scale experiments where scientists spray iron into the waters, literally fertilizing phytoplankton, have created huge man-made algal blooms. Such geoengineering experiments produce diatoms, which pull carbon dioxide out of the air. Experts argue that this practice can […]

WONDER WATER STRAW CLEANSES PUTRID WATER FOR DINKING

WORLDS POOR NOW CAN ACCESS CLEAN DRINKING WATER WITH THE WATER STRAW More than one billion people – one sixth of the world’s population – are without access to safe water supply. At any given moment, about half of the world’s poor are suffering from waterborne diseases, of which over 6,000 – mainly children – […]

REMOVING PESTICIDES FROM WATER THE EASY WAY

Direct capillary nanofiltration removes pesticides from water By Harry Futselaar, Harry van Dalfsen and Bert Welkers A low-pressure capillary nanofiltration (NF) installation, designed as a compact mobile unit, purifies water by removing pesticides and other contaminants from surface and wastewater, according to NORIT Mem-brane Technology, based in Hengelo, The Netherlands. This innovation combines properties of […]
