Deep learning provides deep help—researchers develop publicly available software for rational design of oxide glasses

By Lisa McDonald / May 5, 2020

Designing new oxide glass compositions can be an arduous process when relying on the “cook and look” approach. Researchers at the Indian Institute of Technology Delhi developed composition-property deep learning models for eight key oxide glass properties, and they made the software available publicly online.

To infrared and beyond: Proposed quantum-based photodetector may expand spectral operating range

By Lisa McDonald / May 1, 2020

Since 2000, infrared photodetector technology has experienced rapid development—particularly quantum-based detectors. Now, researchers in Russia, Japan, and the United States developed a model for a detector that could operate in the far-infrared and even terahertz spectral ranges.

Preparing for hypersonic flight—wing shape affects thermal shock behavior of UHTCs

By Jonathon Foreman / March 27, 2020

Ultrahigh-temperature ceramics are promising materials for protecting aircraft wings from friction during hypersonic flight—but thermal shock can cause these ceramics to crack. In the cover article for the March 2020 International Journal of Ceramic Engineering & Science, researchers in China report how wing shape affects thermal shock behavior of UHTCs.

Noisy neighbors? No problem—ceramic-plastic combo might block high-pitched sounds

By Lisa McDonald / March 27, 2020

As people around the world transition to working at home, they face new challenges to focusing—including the sounds of young children stuck home with no school. Two theoretical physicists identified a ceramic-plastic material that can potentially block such high-pitched sounds.

A creeping suspicion—modified concrete creep model considers drying-induced damage

By Lisa McDonald / February 21, 2020

Existing creep damage models for concrete assume compressive and tensile creep are identical, but recent experimental evidence suggests otherwise. Researchers from the United Kingdom and China propose a modified model that accounts for drying-induced damages and load eccentricity to more accurately model creep.

The best of both worlds—ferroelectric crystals exhibit both high transparency and piezoelectricity

By Lisa McDonald / February 7, 2020

Previous attempts to increase transparency of ferroelectric crystals have decreased piezoelectricity. An international team of scientists led by The Pennsylvania State University and Xi’an Jiaotong University now shows that selective engineering of domain walls can improve both properties.

Video: Starlink strife and a possible four-satellite solution

By Lisa McDonald / January 29, 2020

With just under 200 of 12,000 satellites launched, SpaceX’s planned Starlink constellation is already causing major complications for astronomers. Global internet coverage could theoretically be achieved with only four satellites, and a new paper proposes a way to make such a constellation economically feasible.

Modeling murder—Weibull statistics bring new insights to violent mortality rates of Roman emperors

By Lisa McDonald / January 24, 2020

Weibull distribution is widely used in reliability engineering to mathematically describe time-to-failure of materials. A recent paper shows this distribution describes another type of “failure” remarkably well—time-to-violent-death of Roman emperors.

Melting of graphene is simply sublime: Understanding the melting curve of carbon

By Lisa McDonald / January 21, 2020

Researchers have struggled to create an accurate phase diagram of carbon for over 100 years. Now, two researchers from Russia explored melting of graphite and graphene and confirmed some previous hypotheses—and revealed graphene “melting” is in fact sublimation.
