Metal Foam Obliterates Bullets – and That’s Just the Beginning

Composite metal foams are tough enough to turn an armor-piercing bullet into dust on impact. But armor is just the beginning of its potential uses.

Metal Foam Protects From Fire and Heat Twice as Well as Plain Metal

Light-weight composite metal foams (CMFs) are significantly more effective at insulating against high heat than the conventional base metals and alloys that they’re made of, such as steel. The CMF is especially promising for use in storing and transporting nuclear material, hazardous materials, explosives and other heat-sensitive materials, as well as for space exploration.

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.

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.
