Food scientists and farmers alike are keenly interested in boosting crop yields and shortening harvest times, without affecting food safety. A team of researchers led by plasma engineer Kazunori Koga, an associate professor at Kyushu University in Japan, has now developed a new technique to safely achieve both goals using a non-thermal plasma -- a type of partially ionized, low-temperature gas currently used in a wide variety of applications including decontaminating ready-to-eat foods and their packaging, sterilizing medical instruments, reducing pollutants in exhaust gas, and even for wound healing and cancer therapy.
Cartilage is filled with fluid -- about 80% of the volume of the cartilage tissue -- that plays the essential roles of supporting weight and lubricating joint surfaces. Loss of this fluid, called synovial fluid, results in a gradual decrease in cartilage thickness and increase in friction, which is related to the degradation and joint pain of osteoarthritis. Since cartilage is porous, fluid is readily squeezed out of the holes over time. Yet the symptoms associated with osteoarthritis usually take decades to develop. Researchers at the University of Delaware have proposed a mechanism that explains how motion can cause cartilage to reabsorb liquid that leaks out.
The International Space Station (ISS) is in some ways like most homes -- over time, it occasionally requires repairs. When the ammonia cooling system on the exterior of the ISS springs a leak, however, tracking down its location is by no means an easy task. So researchers and engineers from SRS, a manufacturer of test instruments, and NASA’s Johnson Space Center and Goddard Space Flight Center teamed up to create an “Ammonia Leak Locator.” Researchers will describe the new tool and its capabilities at the AVS 62nd International Symposium & Exhibition.
A shed skin of the California King Snake, examined in molecular detail by a team of researchers in Oregon and Germany, may have just yielded one of the reptile's slippery secrets. Using a combination of techniques that allowed the team to explore how molecules are arranged on the surface of the scaly skin, the team discovered a never-before-seen evolutionary adaptation that allows the animal to reduce friction on its underbelly and slither smoothly over surfaces.
Advances in software, materials, and equipment have made it possible to cheaply "print" custom designs -- including such diverse products as airplane engines and action figures. Researchers from the Naval Research Laboratory are doing their part to boost the burgeoning field, popularly known as 3-D printing, but more generally named additive manufacturing. The group has demonstrated that a combination of two technologies -- one to create a thin film and the second to "cut" designs out of the film -- could be a potentially powerful tool to create custom electronic components. They will discuss their findings at the AVS 62nd International Symposium and Exhibition, held Oct. 18-23 in San Jose, Calif.
In March 2011 at Fukushima, the fuel’s cladding, a zirconium alloy used to contain the fuel and radioactive fission products, reacted with boiling coolant water to form hydrogen gas, which then exploded, resulting in the biggest nuclear power-related disaster since Chernobyl. Challenged by this event, two research teams have made progress in developing fuel claddings that are capable of withstanding the high temperatures resulting from a Loss of Coolant Accident (LOCA), like that at Fukushima. Both teams will present their results at the AVS 62nd International Symposium and Exhibition, held Oct. 18-23 in San Jose, Calif.
Whereas human and many animals use teeth to crush or grind food as an initial part of the digestive process, some species such as birds that lack teeth grind food inside the gizzard -- a structure between the mouth and the stomach -- with the help of stones. Another interesting adaptation of this approach to digestion has evolved in most of the Cephalaspidean gastropods, a common type of marine mollusks, who use hardened plates that line the gizzard for crushing or grinding. Recently, a team in Israel studied the properties of gizzard plates of the cephalaspid Philine quadripartite, and they will discuss their work at the AVS 62nd International Symposium and Exhibition.
It's estimated that the U.S. fails to use more than half of the energy it generates -- mostly because it escapes as waste heat. Scientists from the University of Colorado are developing a new type of system to efficiently capture some of that lost heat. They have designed a surface that enhances low frequency thermal radiation, which is easier than higher frequencies to "harvest" directly out of the air and turn into usable DC electricity. The researchers will describe the surface at the AVS 62nd International Symposium and Exhibition, held Oct. 18-23 in San Jose, Calif.
A group of scientists in Sweden has taken an important step towards the goal of peering inside a working cell. They are among researchers around the globe who are seeking a method that enables the observation of proteins, lipids and DNA inside individual cells, as well as gaining a better understanding of how this intricate and interconnected system changes with time. Gijs van der Schot, a Ph.D. student at Uppsala University, will describe the researchers' new approach to imaging during the AVS 62nd International Symposium & Exhibition.
Imagine being fortunate enough to get to study historical art up close, examining the details of every paint stroke applied to the canvases to gain knowledge about artists’ preferred materials and techniques. Then add a team of art scholars and scientists who can provide historical details or even help you to “see” beneath the painting to reveal anything hidden or painted over on its canvas and you will have a sense of the rich collaborations that some museum professionals enjoy every day.
Conservation science is helping make big decisions about preservation methods to protect and save unique and historic U.S. government records—including the iconic and priceless Declaration of Independence—for future generations. During the AVS 61st International Symposium & Exhibition, Jennifer Herrmann, a research chemist and conservation scientist for the National Archives and Records Administration, will describe the role science plays in the preservation of the nation's documents.
Geologist Timothy Rose of the Smithsonian Institution’s Analytical Laboratories is accustomed to putting his lab’s high-tech nanoscale scanning electron microscope (nanoSEM) to work evaluating the mineral composition of rocks and meteorites. Lately, though, the nanoSEM has been enlisted for a different kind of task: determining the authenticity of ancient Mesoamerican artifacts.
A team of University of Maryland researchers is growing vertically aligned “forests” of carbon nanotubes on three-dimensional (3-D) conductive substrates to explore their potential use as a cathode in next-gen lithium batteries.
New technology allows you to print electronic devices in the same way your inkjet printer prints a document or photo. Now researchers at Palo Alto Research Center have used this technique to build a portable X-ray imager and small mechanical devices.
Britain’s nuclear reactors, stainless steel drums, contain metal-clad spent uranium embedded in concrete, and they are highly radioactive. The only way to handle them safely is from behind 2-to-3-meter-thick concrete walls and leaded glass windows using automated equipment. Yet a very small number of these drums have begun to bulge after many years in storage, raising questions about what is happening within. The only way to know for sure is to sneak a peek inside.
A group of North Carolina State University researchers is exploring novel ways to apply semiconductor industry processes to unique substrates to "weave together" multifunctional materials with distinct capabilities. During the AVS 61st International Symposium & Exhibition, they will describe how they were able to "weave" high-strength, highly conductive yarns made of tungsten on Kevlar -- aka body armor material -- by using atomic layer deposition, a process commonly used for producing memory and logic devices.
Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois Urbana-Champaign and their advances suggest a new era of devices that range from green consumer electronics to ‘electroceutical’ therapies, to biomedical sensor systems that do their work and then disappear. The work will be presented at the AVS 61st International Symposium.
Using a common laboratory filter paper decorated with gold nanoparticles, researchers have created a unique platform, known as “plasmonic paper,” for detecting and characterizing even trace amounts of chemicals and biologically important molecules—from explosives, chemical warfare agents and environmental pollutants to disease markers. The work will be described at the AVS 61th International Symposium and Exhibition.
