Jennifer Dionne harnesses light to illuminate nano landscapes

Dionne has created new nanomaterials that steer light in ways that are impossible with natural substances. Her new projects could eventually lead to light-based technologies used to improve drugs or to create new tests to find cancerous cells. There are even applications for renewable energy, for example, designing materials that help solar cells absorb more light.

Asphalt helps lithium batteries charge faster

The Rice lab of chemist James Tour developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material’s promise for use in rapid charge and discharge devices that require high-power density.

Printed meds could reinvent pharmacies, drug research

A technology that can print pure, ultra-precise doses of drugs onto a wide variety of surfaces could one day enable on-site printing of custom-dosed medications at pharmacies, hospitals and other locations.

2017 Golden Goose Award recognizes six researchers whose taxpayer-funded work benefits society

The sixth annual Golden Goose Award ceremony will recognize three teams of scientists whose silly-sounding research has returned serious benefits to society. Led by the American Association for the Advancement of Science, the award committee includes several science societies and organizations and Congressional supporters.

Technique spots warning signs of extreme events

Now engineers at MIT have devised a framework for identifying key patterns that precede an extreme event. The framework can be applied to a wide range of complicated, multidimensional systems to pick out the warning signs that are most likely to occur in the real world.

Squeezing light into infinitesimally thin lines

Researchers have demonstrated a new mode of electromagnetic wave, called a “line wave,” which travels along an infinitesimally thin line along the interface between two adjacent surfaces with different electromagnetic properties. The scientists expect that line waves will be useful for the efficient routing and concentration of electromagnetic energy, such as light, with potential applications in areas ranging from integrated photonics, sensing and quantum processes to future vacuum electronics.

The Goldilocks Wing: Popular Airfoil Design Defies Aerodynamic Standards

Since the Wright brothers took to the sky in 1903 aboard their notorious, dual-winged biplane, we have seen countless wing designs of various shapes and sizes used on aircraft. Each of these wings have a particular cross-section design, known as an airfoil, that follows the textbook standard relationship between lift and the angle of attack. However, Professor Geoff Spedding, of USC Viterbi’s Aerospace and Mechanical Engineering Department, found otherwise while performing careful experiments in the same standard conditions, but at a smaller scale. His results highlight the disparity between experiments, computations and aerodynamic models and how much work still needs to be done before reaching agreement as designers endeavor on small-scale flight – the next generation of drones.

Thin, flexible device could provide efficient cooling for mobile electronics – or people

Engineers and scientists from the UCLA Henry Samueli School of Engineering and Applied Science and SRI International, a nonprofit research and development organization based in Menlo Park, California, have created a thin flexible device that could keep smartphones and laptop computers cool and prevent overheating.

Researchers demonstrate broad range, cost-effective infrared lasers for photonic, medical applications

The electronics industry has driven the digital revolution for an unprecedented success based on Si. As a result, there has been a tremendous effort to broaden the reach of Si technology to build integrated optic and photonic circuits. Supported by Air Force Office of Scientific Research (AFOSR) National Aeronautics and Space Administration (NASA) Established Program to Stimulate Competitive Research (EPSCoR), and National Science Foundation (NSF), researchers from a multi-institutional team have demonstrated infrared lasers made of the inexpensive germanium tin (GeSn) alloy grown on silicon (Si) substrates. The laser operation wavelength coverage is from 2 to 3 micron, with the maximum operating temperature reaching 180 Kelvin.

First On-Chip Nanoscale Optical Quantum Memory Developed

For the first time, an international team led by engineers at Caltech has developed a computer chip with nanoscale optical quantum memory.
