Scientists have developed a new method to differentiate very weak and short sound waves from longer ones. When used in acoustic imaging, their technology makes it possible to detect only the outline of objects. This type of measuring method delivers similar results to the edge detection filter in image-processing software, which allows the outline of prominent photo objects to be identified with the click of the mouse.
Engineers have invented a transparent material that improves the efficiency of solar cells by radiating thermal energy (heat) into space. Every time you stroll outside, you emit energy into the universe: Heat from the top of your head radiates into space as infrared light. The researchers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon.
Using ultrafast beams of extreme ultraviolet light streaming at a 100,000 times a second, researchers have pushed the boundaries of a well-established imaging technique. Not only did they make the highest resolution images ever achieved with this method at a given wavelength, they also created images fast enough to be used in real time. Their new approach could be used to study everything from semiconductor chips to cancer cells.
Atoms are the building blocks of all matter on Earth, and the patterns in which they are arranged dictate how strong, conductive or flexible a material will be. Now, scientists at UCLA have used a powerful microscope to image the three-dimensional positions of individual atoms to a precision of 19 trillionths of a meter, which is several times smaller than a hydrogen atom.
Researchers have uncovered a new species of plant-eating dinosaur in Alaska, according to a report published Tuesday.
A researcher from Florida Atlantic University has come up with a unique way to monitor sickle cell disease -- a serious blood disorder -- using a smart phone.
At EPFL, the Center for Research in Plasma Physics (CRPP) has become the Swiss Plasma Center (SPC), and for good reason: the Center is upgrading its facilities and expanding its scope of activities.
A team of physicists has defied conventional wisdom by inducing stable ferroelectricity in a sheet of strontium titanate only a few nanometers thick. The discovery could open new pathways to find new materials for nanotechnology devices. It also contradicts the expected behavior of ferroelectric materials, which normally lose stable ferroelectric polarization as they are made thinner.
Researchers recently released a new CAE software program, and its users are already calling it a "gift from heaven." The software assists in optimizing the design of parts for just about anything—from bicycles and airplanes to bridges and furniture. It is intended to help designers quickly identify component shapes—known as topologies—that maintain their structural integrity while using the least amount of material possible.
Discovery of a new photonic crystal where light propagates through the surface without being scatteredSeptember 21, 2015 12:11 pm | by National Institute for Materials Science (NIMS) | Comments
Researchers elucidated a new principle whereby electromagnetic waves including light propagate on the surface in a photonic crystal without being scattered. By merely slightly adjusting positions of insulator or semiconductor cylinders (nanorods) in a honeycomb lattice, electromagnetic waves can propagate without being scattered even at corners of crystal or by defects.
Researchers created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state. This material made of nanomagnets might well be refined for electronic applications of the future—such as for more efficient information transfer.
Canada’s Canadian Hydrogen Intensity Mapping Experiment radio telescope could offer the first set of regular data from fast radio bursts. Researchers are proposing a new way to calculate distances in the cosmos using mysterious bursts of energy. The method allows researchers to position distant galaxies in three dimensions and map out the cosmos. CHIME has the potential of seeing tens to hundreds of these events per day.
Researchers studying a degenerative disease in former athletes say 11 of 12 brains of deceased former NFL players tested over the past year showed signs of chronic traumatic encephalopathy, or CTE, continuing a trend they've been tracking.
Harvard scientists are taking a hard look at northeastern forests for evidence of a potential springtime scramble, one that could be triggered if age-old growth cues are disrupted by climate change.
MIT-led team develops method for scaling up production of thin electronic material.
