A noble gas cage: New material traps gases from nuclear fuel better
When nuclear fuel gets recycled, the process releases radioactive krypton and xenon gases. Naturally occurring uranium in rock contaminates basements with the related gas radon. A new porous material called ...
Australia drying caused by greenhouse gases and ozone
NOAA scientists have developed a new high-resolution climate model that shows southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions ...
New materials for capturing carbon dioxide from combustion gases
(Phys.org) —Carbon dioxide is both a culprit in global warming and also responsible for keeping the Earth warm enough to support life as we know it. It is odorless and colorless, often represented by a ...
Study reveals four new man-made gases in the atmosphere
Scientists at the University of East Anglia have identified four new man-made gases in the atmosphere – all of which are contributing to the destruction of the ozone layer.
An inside look at metal-organic framework in action
(Phys.org) —A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for ...
New simulation shows disk anomalies around stars may not be planets after all
Noble gases hitch a ride on hydrous minerals
The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't ...
How do you feed 9 billion people?
An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
Vibrations reveal how material 'takes a breath'
A combination of supercomputer calculations and a bombardment of high-energy particles has revealed how a new kind of material opens its pores and 'breathes'.
Permafrost soil: Possible source of abrupt rise in greenhouse gases at end of last Ice Age
Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have identified a possible source of carbon dioxide (CO2) and other greenhouse gases that were abruptly released ...
Chemists develop porous molecules that bind greenhouse gases
A team of University of Houston (UH) chemistry researchers have developed a molecule that assembles spontaneously into a lightweight structure with microscopic pores capable of binding large quantities of ...
Where did all the xenon go?
(Phys.org) —The noble gas xenon should be found in terrestrial and Martian atmospheres, but researchers have had a hard time finding it.
Better bomb-sniffing technology with new detector material
University of Utah engineers have developed a new type of carbon nanotube material for handheld sensors that will be quicker and better at sniffing out explosives, deadly gases and illegal drugs.
NIST 'combs' the atmosphere to measure greenhouse gases
By remotely "combing" the atmosphere with a custom laser-based instrument, researchers from the National Institute of Standards and Technology (NIST), in collaboration with researchers from the National Oceanic ...
