Dielectric Film Has Refractive Index Close to Air for Photonics Applications
Researchers have developed a dielectric film that has optical and electrical properties similar to air, but is strong enough to be incorporated into electronic and photonic devices – making them both more efficient and more mechanically stable.
Proof-Of-Concept Study Shows Potential for Using Ultrasound to Detect Early Signs of Preterm Labor
An international team of researchers has conducted a proof-of-concept study that raises the possibility of using ultrasound techniques to detect cervical stiffness changes that indicate an increased risk of preterm labor in pregnant women.
Study Finds Metal Foams Capable of Shielding X-rays, Gamma Rays, Neutron Radiation
Research shows lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.
Researchers Find Nanowires Have Unusually Pronounced ‘Anelastic’ Properties
Researchers have found that nanoscale wires (nanowires) made of common semiconductor materials have a pronounced anelasticity – meaning that the wires, when bent, return slowly to their original shape rather than snapping back quickly.
Researchers Create Transparent, Stretchable Conductors Using Nano-Accordion Structure
Researchers have created stretchable, transparent conductors that work because of the structures’ “nano-accordion” design. The conductors could be used in applications such as flexible electronics, stretchable displays or wearable sensors.
Lightweight Membrane Can Significantly Reduce In-Flight Aircraft Noise
Riding in a helicopter or airplane can be a noisy experience for passengers. But researchers have developed a membrane that can be incorporated into aircraft to drastically reduce the low-frequency noise that penetrates the cabin.
New Technique Helps Probe Performance of Organic Solar Cell Materials
Researchers have developed a way to determine the role that a material’s structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The finding will help guide future research and development efforts.
Wearable Sensor Smooths Path to Long-Term EKG, EMG Monitoring
Researchers have developed a wearable sensor that uses silver nanowires to monitor electrophysiological signals. The sensor is as accurate as the “wet electrode” sensors used in hospitals for EKGs and EMGs, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.
Nanoparticle Allows Low-Cost Creation of 3-D Nanostructures
Researchers have developed a new lithography technique that uses nanoscale spheres to create 3-D structures with biomedical, electronic and photonic applications.
Hunt Is Home to Animatronic Wolf
Using 3-D scanning technology, computer-aided design software and good old-fashioned elbow grease, two engineering students create a capstone project for the ages: an animatronic timber wolf for the high-tech Hunt Library.
