Engineering Researchers Help NASA Learn More From the Stars
Telescopes created in the Precision Engineering Consortium (PEC) in NC State’s College of Engineering will help NASA scientists gain a better understanding of the process by which dense regions within molecular clouds in interstellar space, referred to as stellar nurseries, collapse to form stars. The region of interest is stars that are 2,500 light years away from the earth – meaning the light reaching the telescope left the star 2,500 years ago.
New Metamaterial Manipulates Sound to Improve Acoustic Imaging
Researchers have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes through the metamaterial.
Hassan’s Giving Takes Flight
Mechanical and aerospace engineering professor Hassan A. Hassan has spent most of his career at NC State and recently established the Hassan Family Fellowship to provide two-year stipends for master’s candidates and four-year stipends for Ph.D. candidates in the College of Engineering.
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.
