When laser light is used to drive the motion of a thin, rigid membrane, the membrane vibrates in resonance with the light. The resulting patterns can be visualized through an array of quantum dots, where these tiny structures emit light at a frequency that responds to movement. The advance is reported this week in a cover article of Applied Physics Letters.
In 2014, the Rosetta probe became the first spacecraft to orbit the nucleus of a comet and later land on its surface. The mission ended in 2016 with the probe’s dive into the comet but its close-up studies of the comet continue to yield scientific insights. In a presentation at the AVS 64th annual International Symposium and Exhibition, researchers will describe findings from Rosetta’s ROSINA instrument, which obtained the first detailed, in situ measurements of the chemical composition of a comet’s atmosphere, or coma.
Solid-state batteries, which eschew the flammable and unstable liquid electrolytes of conventional lithium-ion batteries, could be a safer option. Now, researchers have demonstrated a new way to produce more efficient solid-state batteries. This proof-of-principle study may lead to safer and more compact batteries useful for everything from sensor networks to implantable biomedical devices. Researchers at the University of Maryland will present this work during the AVS 64th International Symposium and Exhibition, in Tampa, Florida.
Among the diverse research studies being presented at this year’s 64th AVS International Symposium and Exhibition are two biomaterial interfaces sessions that feature some highly unusual applications of engineering. The first describes the use of stress forces -- more commonly employed to evaluate the failure mechanisms of materials and devices made from them -- to discover how barnacles stick to surfaces. The second explores the development of two novel mechanical systems, both smaller than the eye can see, for use with gas molecules: one to detect them with ultra-high sensitivity and the other to precisely measure their molecular weights.
The report, “The Opioid Epidemic: From Evidence to Impact,” maps out a blueprint for national action on the epidemic and details dozens of concrete, evidence-based steps for everyone working to fight the opioid crisis in America – from the health care, advocacy, nonprofit, government, academic, and business sectors.
A Salisbury University program to help create jobs throughout the mid-Atlantic will continue another five years, thanks to a new $1 million gift from the Philip E. and Carole R. Ratcliffe Foundation of Baltimore.
A new grant will assist the University of Maryland SAFE Center and the Prince George's County Police Department in aiding victims of human trafficking.
JoAnn Trejo, professor in the Department of Pharmacology at University of California, San Diego, has been named the 2017 winner of the E.E. Just Award by the American Society for Cell Biology (ASCB). Trejo will receive the award and present a lecture on her research at the 2017 ASCB|EMBO Meeting on December 3 in Philadelphia.
Astronomers using NASA’s Hubble Space Telescope have found a blistering hot planet outside our solar system where it “snows” sunscreen. The problem is the sunscreen (titanium dioxide) precipitation only happens on the planet’s permanent nighttime side.
St. Mary’s College of Maryland’s Board of Trustees authorizes in-state tuition to students from Puerto Rico and the U.S. Virgin Islands who have been displaced by recent hurricanes.
Seeing junk food distracts people from work nearly twice as much as seeing healthy food, but after a few bites, people find it no more engaging than kale. The study underscores people’s implicit bias for fatty, sugary foods.
More than 50 million Americans have food allergies and often just trace amounts of allergens can trigger life-threatening reactions. Now, researchers have developed a $40 device that fits on a key chain and can accurately test for allergens, like gluten or nuts, in a restaurant meal in less than 10 minutes.
Diamond is largely recognized as the ideal material in wide bandgap development, but realizing its full potential in field-effect transistors has been challenging. Researchers incorporate a new approach by using the deep-depletion regime of bulk-boron-doped diamond MOSFETs. The new proof of concept enables the production of simple diamond MOSFET structures from single boron-doped epilayer stacks. This method increases the mobility by an order of magnitude. The results are published this week in Applied Physics Letters.
ASHP (American Society of Health-System Pharmacists) and the University of Utah Drug Information Service have developed a fact sheet that provides an outline of potential actions for healthcare organizations to consider in managing shortages of small-volume parenteral solutions (SVPs).
Women account for half of all cases of high blood pressure (hypertension) in the U.S., yet the majority of hypertension research focuses on men. A review of more than 80 studies highlights sex differences in hypertension-related kidney (renal) disease and explores possible reasons why women respond differently than men. The article, published in the American Journal of Physiology—Renal Physiology, emphasizes the need for more hypertension research in females.
The San Francisco State University biology professor will be recognized for her work in evidence-based teaching and biology education research.
A new type of DNA editing enzyme, developed in HHMI Investigator David Liu’s lab, lets scientists directly and permanently change single base pairs of DNA from A•T to G•C. The process could one day enable precise DNA surgery to correct mutations that cause human diseases.
Advances in materials science have improved the composition of materials used in photocathode production that can operate at visible wavelengths and produce a beam with reduced transverse electron momentum spread. Despite these advances, the surface roughness of the photocathode continues to limit beam properties. A research team created computer models to bridge the gap between theoretical and experimental studies to provide a better picture of the physics at the surface of the photocathode. The results are published this week in the Journal of Applied Physics.
Thin-film piezoelectrics, with dimensions on the scale of micrometers or smaller, offer potential for new applications where smaller dimensions or a lower voltage operation are required. Researchers have demonstrated a new technique for making piezoelectric microelectromechanical systems by connecting a sample of lead zirconate titanate piezoelectric thin films to flexible polymer substrates. They report their results in this week’s Journal of Applied Physics.
