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.

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.

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.
