Video: I “Spot” a new application—novel uses of robots during the COVID-19 pandemic

By Lisa McDonald / August 5, 2020

When Boston Dynamics premiered their dog-like robot Spot in September 2019, they imagined the robot being used in hazardous environments, such as construction and electric utility. Now in the midst of the COVID-19 pandemic, Spot has stepped into some unusual roles that previously were not considered primary applications.

Trap-and-zap degradation: Photocatalysis techniques for destroying antibiotic resistant bacteria and genes

By Lisa McDonald / August 4, 2020

Antibiotic resistant bacteria and antibiotic resistance genes are an increasing concern in water contamination. Rice University researchers are exploring photocatalysis techniques to destroy antibiotic resistance genes, and two papers published this year explore “trap-and-zap” strategies.

A double-edged sword—reverse engineered 3D-printed parts show security risk presented by machine learning

By Lisa McDonald / July 31, 2020

Machine learning is poised to play a big role in speeding up materials discovery and commercialization—but could such techniques present a risk to the global additive manufacturing market as well? Researchers at New York University showed they could potentially steal trade secrets by reverse engineering 3D-printed parts using machine learning.

Modeling teaches old dogs new tricks: Viscosity predictions from dilatometry and DSC

By Jonathon Foreman / July 31, 2020

Determining viscosity of a glass through experiment is a slow and expensive process. In two recent papers published in JACerS, Penn State professor John Mauro and his colleagues show how it can be predicted much easier by using dilatometry and DSC to calculate parameters for a glass viscosity model that was proposed in 2009.

Video: Next-gen Gorilla Glass improves both scratch and drop resistance

By Lisa McDonald / July 29, 2020

Historically, Corning focused on improving drop resistance rather than scratch resistance when developing new Gorilla Glass. But Gorilla Glass Victus—the latest version announced last week—improves both resistances, with significant results.

Storing charge in sodium-ion batteries: Study supports “three-stage” model for hard carbon anodes

By Lisa McDonald / July 28, 2020

In developing sodium-ion batteries, hard carbon is the material most often used for the anode, but unknowns concerning the charge storage mechanism in this material hinder further development. Researchers have proposed several models to explain the charge storage mechanism, and a recent study lends support for the three-stage “adsorption-intercalation-adsorption” process.

Identify molecular ‘fingerprints’: Proposed graphene-based nanofocused sensor may improve molecular analysis

By Lisa McDonald / July 24, 2020

Mid-infrared spectroscopy is an important tool for nondestructive analysis of molecules, but it cannot analyze nanometric volumes very well. One way to improve nanometric analysis is through a technique called nanofocusing, and researchers in Spain and Russia proposed an improved nanofocusing technique using graphene.

Video: Vitrification of human tissue

By Lisa McDonald / July 22, 2020

Vitrification is the process through which a material turns into a glass or glasslike substance by undergoing rapid cooling. Though the discovery this year that a man’s brain vitrified during the Mount Vesuvius eruption surprised some people, vitrification of human tissue is actually a well-established practice in fertility treatment.
