Objects created using 3D printing have a common flaw: They are fragile and often fall apart or lose their shape. Researchers at Purdue University and Adobe's Advanced Technology Labs have jointly developed a program that automatically imparts strength to objects before they are printed, spurring on the trend of 3D printing.
A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale, but lose their edge when applied to time frames shorter than three decades and on sub-continental scales.
An international team of scientists has discovered a new class of materials that could prove to be useful in developing new methods of creating computer memory. The research team explored layered heterostructures at the atomic scale, in which different materials were deposited in layers a few atoms thick. They discovered that the new class of materials boasts an attractive property—ferroelectricity.
Topological insulators are exotic materials, discovered just a few years ago, that hold great promise for new kinds of electronic devices. The unusual behavior of electrons within them has been very difficult to study, but new techniques developed by a team of researchers could help unlock the mysteries of exactly how electrons move and react in these materials, opening up new possibilities for harnessing them.
Using ultralow input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated, for the first time, how low-power optical nanotweezers can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples.
An international team of physicists is working to ascertain more about the fundamental physical laws that are at work in a process known as convection. The team's new finding specifies the way that the temperature of a gas or liquid varies with the distance from a heat source during convection. The research is expected to eventually help engineers with applications such as the design of cooling systems.
Diatoms, tiny marine life forms that have been around since the dinosaurs, could finally make biofuel production from algae truly cost effective—because they can simultaneously produce other valuable products such as semiconductors, biomedical products, and even health foods. Engineers at Oregon State University concede that such technology is pushing the envelope a bit. But it's not science fiction.
When the Dark Energy Camera opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, more than 120 members of the Dark Energy Survey eagerly awaited the first snapshots. Those images have now arrived.
Chemists at the University of California, San Diego have developed a method that, for the first time, provides scientists the ability to attach chemical probes onto proteins and subsequently remove them in a repeatable cycle. Their achievement will allow researchers to better understand the biochemistry of naturally formed proteins in order to create better antibiotics.
The transparent electronics that were pioneered at Oregon State University may find one of their newest applications as a next-generation replacement for some uses of non-volatile flash memory, a multi-billion dollar technology nearing its limit of small size and information storage capacity.
University of Texas at Austin physicists have been awarded a U.S. patent for an invention that could someday be used to turn nuclear waste into fuel, thus removing the most dangerous forms of waste from the fuel cycle. The researchers have patented the concept for a novel fusion-fission hybrid nuclear reactor that would use nuclear fusion and fission together to incinerate nuclear waste.
An international team of researchers have demonstrated a microscopy method to identify magnetic defects in an array of magnetic nanostructures. The method represents an important step towards identifying, measuring, and correcting the magnetic properties of defective devices in future information storage technologies.
Few modern materials have achieved the fame of silicon, a key element of computer chips. The next generation of computers, however, may not rely so much on silicon. University at Buffalo researchers are among scientists working to identify materials that could one day replace silicon to make computing faster. Their latest find: A vanadium oxide bronze whose unusual electrical properties could increase the speed at which information is transferred and stored.
Nanoengineers at the University of California, San Diego have developed a novel technology that can fabricate, in mere seconds, microscale 3D structures out of soft, biocompatible hydrogels. Near term, the technology could lead to better systems for growing and studying cells, including stem cells, in the laboratory. Long-term, the goal is to be able to print biological tissues for regenerative medicine.
Researchers at Columbia University have developed a new software that can simultaneously calculate the carbon footprints of thousands of products faster than ever before. The software complies with the latest product LCA guidelines sponsored by the World Resources Institute, and any carbon footprint it calculates can easily be audited against this standard.
Researchers at the Indian Institute of Technology have used techniques from information theory to identify DNA introns and exons an order-of-magnitude faster than previously developed methods. The researchers were able to achieve this breakthrough in speed by looking at how electrical charges are distributed in the DNA nucleotide bases.
A theoretical physicist from Swinburne University of Technology and colleagues from Saudi Arabia and the U.S. have discovered a specialty-engineered surface that allows liquids to boil without bubbling. To suppress bubbling while boiling, the team of researchers used a highly water-repellent surface to control the boiling state of a liquid.
A professor from Tel Aviv University is reconfiguring existing complementary metal-oxide-semiconductor (CMOS) chips designed for computers and turning them into high-frequency circuits. The ultimate goal of this project is to produce chips with radiation capabilities that are able to see through packaging and clothing to produce an image of what may be hidden beneath.
Climate change is expected to increase the frequency of intense spring rain storms in the Great Lakes region throughout this century and will likely add to the number of harmful algal blooms and "dead zones" in Lake Erie, unless additional conservation actions are taken, according to a University of Michigan aquatic ecologist.
Purdue University researchers have created a new type of miniature pump activated by body heat that could be using in drug-delivery patches powered by fermentation. The micropump contains Baker's yeast and sugar in a small chamber, and when water is added and the patch is placed on the skin, the body heat and added water causes the yeast and sugar to ferment, generating a small amount of carbon dioxide gas, which pushes against a membrane and has been shown to pump for several hours.
Massachusetts Institute of Technology researchers have developed a new technique for magnetically separating oil and water that could be used to clean up oil spills. They believe that, with their technique, the oil could be recovered for use, offsetting much of the cleanup cost.
An international team led by University of Toronto physicists has developed a simple new technique using Scotch poster tape that has enabled them to induce high-temperature superconductivity in a semiconductor for the first time.
