Several oxides are routinely used as sintering aids in the fabrication of zirconia toughened alumina. While the individual effects of these oxides are well recorded, the effect of multiple oxide inclusions is unclear. Researchers from several institutions in Bangladesh investigated the combined effect of these oxides on the zirconia toughened alumina system.

Current methods for controlling “runaway” thermal reactions such as combustion and pyrolysis remain rather rudimentary. Researchers led by North Carolina State University developed a new nanocoating that, when applied to a material before combustion, allows for the reaction rate and direction of ignition propagation to be controlled.

Lithium metazirconate (LZO) has demonstrated promise as an electrode coating in solid-state batteries, and some researchers are exploring the use of LZO as a solid-state electrolyte itself. However, to date, all electrochemical testing on LZO for this application has been performed on pressed discs rather than thin films. Researchers in Argentina and Spain developed an aqueous forming route to obtain LZO films by tape casting.

Car windows that are damaged beyond repair have to date been reused for less demanding purposes, such as bottles or insulation. A pilot project led by the Audi Group showed defective car glass can be recycled successfully back into new windshields, and the company plans to shift this glass into standard production starting September 2023.

Significant progress in creating optics with nonuniform (gradient) refractive indices has been made over the past two decades. In 2020, researchers at the University of Illinois Urbana-Champaign proposed a unique way to use direct laser writing to achieve even greater control over the refractive index. A new open-access paper details refinements to their so-called SCRIBE method.

Verifying the purity of ultrahigh-purity materials can be a challenge. Researchers in Italy and Norway developed a new analytical protocol based on laser ablation paired with inductively coupled plasma mass spectrometry to determine the purity of silicon carbide.

Starting materials can often be derived from different sources, but the impact that material source has on a product’s properties is generally less studied than other factors, such as synthesis technique. Researchers from Wuhan University of Technology explored the effect of different magnesium sources on the production of magnesium aluminate spinel.
