Save “cold,” hard cash—cold sintering offers financial, environmental benefits to ceramic manufacturing

By Lisa McDonald / November 8, 2019

Decarbonizing manufacturing processes is a focus of the ceramic industry. In a recent paper, researchers performed a techno-economic analysis to show how the cold sintering process, a recently developed manufacturing technique, could help reach this goal.

Tune shear-thickening fluid viscosity with acoustics

By Lisa McDonald / November 1, 2019

Dilatant fluids, commonly termed shear-thickening fluids, can complicate manufacturing by jamming pumping and mixing equipment. Cornell University researchers investigated softening dilatant fluids using ultrasonic waves to make them easier to handle.

No furnace necessary: Lasers weld ceramics at room temperature

By Lisa McDonald / October 11, 2019

Welding ceramics traditionally requires high temperatures and long-term exposure. Researchers from the University of California, San Diego, and the University of California, Riverside, discovered ceramics can be welded at room temperature using ultrafast pulsed lasers.

Ultrathin glass goes ultrawide

By Jonathon Foreman / August 30, 2019

Glass panels with large dimensions can be fabricated using the float glass process—but can the process also fabricate ultrathin glass? Scientists at the State Key Laboratory for Float Glass in China report it can—while still retaining large dimensions.

Hero or villain? Opposing arguments for the environmental impact of smartphones

By April Gocha / August 16, 2019

The smartphone industry is often considered to have an increasingly negative impact on the environment. But an opposing argument that smartphones are the heroes, rather than villains, of this story exists as well. How could that be?

Not so tough now: h-BN more amenable to bonding after reduction reaction

By Lisa McDonald / August 16, 2019

Hexagonal boron nitride (h-BN) has many excellent properties but does not bond well with other elements. Chemists at Rice University found a particular reduction reaction allows h-BN to bond readily with carbon chains.

Sound science and engineering at all stages of research

By Jonathon Foreman / August 9, 2019

Sound science and engineering occur at all stages of the research process—a fact evident in ACerS journals. See how ACerS promotes sound science throughout the research process in two recent articles published in two ACerS journals.
