For the first time, researchers have successfully 3D printed chalcogenide glass, a unique material used to make optical components that operate at mid-infrared wavelengths. The ability to 3D print this glass could make it possible to manufacture complex glass components and optical fibers for new types of low-cost sensors, telecommunications components and biomedical devices.

In The Optical Society (OSA) journal Optical Materials Express, researchers from the Centre d’Optique, Photonique et Laser (COPL) at Université Laval in Canada, Patrick Larochelle and his colleagues, describe how they modified a commercially available 3D printer for glass extrusion. The new method is based on the commonly used technique of fused deposition modeling, in which a plastic filament is melted and then extruded layer-by-layer to create detailed 3D objects.

“3D printing of optical materials will pave the way for a new era of designing and combining materials to produce the photonic components and fibers of the future,” said Yannick Ledemi, a member of the research team. “This new method could potentially result in a breakthrough for efficient manufacturing of infrared optical components at a low cost.”

Researchers from North Carolina State University and the University of Texas at Austin have developed a technique for detecting types of malware that use a system’s architecture to thwart traditional security measures. The new detection approach works by tracking power fluctuations in embedded systems.

“Embedded systems are basically any computer that doesn’t have a physical keyboard – from smartphones to Internet of Things devices,” says Aydin Aysu, co-author of a paper on the work and an assistant professor of electrical and computer engineering at NC State. “Embedded systems are used in everything from the voice-activated virtual assistants in our homes to industrial control systems like those used in power plants. And malware that targets those systems can be used to seize control of these systems or to steal information.”

At issue are so-called micro-architectural attacks. This form of malware makes use of a system’s architectural design, effectively hijacking the hardware in a way that gives outside users control of the system and access to its data. Spectre and Meltdown are high-profile examples of micro-architectural malware.

Innolith AG, Swiss maker of rechargeable Inorganic Battery Technology, says they have the world’s first 1000 Wh/kg rechargeable battery. This would triple the range of electric cars. The Innolith Energy Battery would radically reduce costs by not using exotic and expensive materials.

Innolith will make an initial pilot production in Germany and then create licensing partnerships with major battery and automotive companies. Development and commercialization of the Innolith Energy Battery is anticipated to take between three and five years.

New measurements from NASA’s Hubble Space Telescope confirm that the universe is expanding roughly 9 percent faster than expected based on its trajectory observed shortly after the Big Bang, according to a new study.

The Hubble Space Telescope measurements, which were published in the Astrophysical Journal Letters on Thursday, minimize the chances that the disparity is an accident from 1 in 3,000 to only 1 in 100,000 and suggest new physics might be needed to better comprehend the cosmos, said a Johns Hopkins University press release.
