Get inked with ceramics—or maybe not

By Lisa McDonald / September 6, 2019

Titanium dioxide is the second most common pigment used in tattoo inks. Yet researchers of two studies warn nano-TiO2 could travel to your lymph nodes—and bring metal particles from the needle along with it.

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.

Nearing the theoretical limit of strength—nanoparticles toughen oxide glass

By Lisa McDonald / August 13, 2019

Reducing oxide glass brittleness is an active area of research. Researchers at the University of California, Los Angeles, created a tough oxide glass with a stress-modulus relationship near the theoretical limit by dispersing nanoparticles in a glass melt.

No pressure, no problem—researchers create transparent nanoceramics using pressureless crystallization

By Lisa McDonald / July 16, 2019

Transparent ceramics offer advantages over conventional glass and single-crystal technologies—could transparent nanoceramics be even more advantageous? Researchers show how pressureless glass crystallization could offer an easier way to synthesize transparent nanoceramics.

Pantry ingredients help cook cakes and carbon nanotubes equally

By Lisa McDonald / July 2, 2019

Compared to common metallic catalysts, researchers from MIT, Harvard, and NIST found sodium catalysts synthesize carbon nanotubes at far lower temperatures and do not leave residue behind in the final product.

Freestanding perovskite films reach a new low

By Lisa McDonald / June 18, 2019

Must perovskite oxide films consist of a minimum number of layers to retain stability? Researchers in China and the United States found a specific deposition technique lets them deposit freestanding perovskite sheets thinner than a suggested critical limit.
