Robot uses capacitive sensors in soft hands to separate recyclable materials

By April Gocha / April 23, 2019

Researchers at MIT developed a robot that can effectively separate mixed recyclable materials, using two flexible silicone “hands” to feel the difference between paper, metal, and plastic.

No more inert atmospheres—Molten salt synthesis prevents oxidation of materials in air

By Lisa McDonald / April 19, 2019

Nonoxide ceramics typically undergo high-temperature synthesis in an inert atmosphere to prevent spontaneous oxidation. Researchers at Forschungszentrum Jülich have now found that potassium bromide keeps nonoxide ceramics from oxidizing when synthesized in normal air.

Microwave processing of glass frit promises significant energy reduction

By Jonathon Foreman / April 9, 2019

Frit produced by researchers in Spain using a pre-production scale microwave processing method compared well to commercial frit prepared in a traditional gas-fired continuous furnace—and it used 64 percent less energy per kilogram of frit to produce.

Vacuum plasma spraying: A different way to apply UHTC coatings

By Lisa McDonald / April 5, 2019

Ultra-high temperature ceramic coatings are conventionally applied to composites using chemical vapor deposition. In a recent study, researchers from Korea experimented with applying UHTC coatings using a vacuum plasma spray process instead.

A materials dead end? The unraveling of the recycling cycle

By April Gocha / March 26, 2019

Although 91 percent of the plastics discarded on this planet have never been recycled, the materials recycling status of glass has to be better…right? A daunting look at the current state of recycling.

Laying the groundwork: Understanding how external fields affect ceramic sintering

By Jonathon Foreman / March 22, 2019

Field-assisted sintering techniques (FAST) offer a way to lower firing temperatures and cycle times of sintering processes. The feature article in the January 2019 issue of Journal of the American Ceramic Society summarizes discussions from a workshop aimed at understanding the mechanisms behind FAST.

No need for thermal treatment—this process heals cracks in ceramic composites at room temperature

By Lisa McDonald / March 1, 2019

Osaka University researchers found that anodic oxidation allows them to self-heal ceramic-based composites at room temperature, bypassing high-temperature treatments that can cause undesirable reactions.

Improving toughness of nanocrystalline ceramics

By Faye Oney / July 10, 2018

Researchers have demonstrated a new toughening mechanism for nanoceramics by studying weak interfaces in nanocrystalline ceramics. Their method could improve impact resistance without compromising functional properties.
