Little-studied man-made gases have big warming potential
(Phys.org) —The total warming impact of 25 major synthetic greenhouse gases has been examined by an international team, led by researchers from the University of Bristol.
Next-generation coatings and sensors that can operate in extreme conditions
Tata Steel has formed a strategic partnership with the prominent UK research body, the Engineering and Physical Sciences Research Council (EPSRC), to develop a range of innovations that will include graphene-coated steels ...
Cleaner NASA rover sees its shadow in Martian spring
(Phys.org) —Late afternoon lighting produced a dramatic shadow of NASA's Mars Exploration Rover Opportunity photographed by the rover's rear hazard-avoidance camera on March 20, 2014.
New system could provide first method for filtering light waves based on direction
Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color ...
Nanoparticle based coating for aircraft engines may triple service life and reduce fuel consumption
Researchers at University West in Sweden have started using nanoparticles in the heat-insulating surface layer that protects aircraft engines from heat. In tests, this increased the service life of the coating ...
New technique makes LEDs brighter, more resilient
Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gallium ...
Amount of phosphorus has risen in the Sea of Bothnia and the Baltic Proper
R/V Aranda, the research vessel of Finnish Environmental Institute SYKE has during the winter 2014 monitored the environmental status of the Baltic Sea on an area that is significantly larger compared with previous years, ...
How wind helps Antarctic sea ice grow, even as the Arctic melts
Strong winds linked to climate change and the hole in the ozone layer are driving a steady increase in Antarctic sea ice, even as Arctic levels continue to shrink dramatically, a new report shows.
Samsung mass producing advanced 4Gb DDR3, using 20 nanometer process technology
Samsung Electronics today announced that it is mass producing the most advanced DDR3 memory, based on a new 20 nanometer process technology, for use in a wide range of computing applications.
Flexible, semi-transparent ultrathin solar cells
A lot of research has been done on graphene recently—carbon flakes, consisting of only one layer of atoms. As it turns out, there are other materials too which exhibit remarkable properties if they are ...
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.
Researchers use atomic layer deposition to grow bimetallic nanoparticles
Since the dawn of the Bronze Age, people have appreciated the advantages of using alloys rather than single metals to make better materials. Recently, scientists have discovered a recipe for making tiny two-metal ...
Soft metal weld makes for stronger infrastructure
Scientists have found applying a soft metal layer before welding hard metals can act as a sufficient buffer to address fatigue behaviour in welded metal.
Graphene's love affair with water
Graphene has proven itself as a wonder material with a vast range of unique properties. Among the least-known marvels of graphene is its strange love affair with water.
