Despite the meteoric rise of MXenes from discovery to commercial products in only a decade, the environmental impacts of MXene synthesis have not been assessed systematically. ACerS member Babak Anasori helped lead two recent studies that provided a life cycle assessment and step-by-step guide for synthesizing Ti3C2Tx MXenes, respectively.

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.

Growing carbon nanotubes on metal foils rather than traditional silicon or quartz substrates would allow the process to be easily integrated into large-scale manufacturing processes. But metal foils present other challenges, such as reactivity at high temperatures. Lawrence Livermore National Laboratory researchers published a review paper summarizing efforts to overcome these challenges.

Automating experiments can help speed up the materials development process. Researchers led by North Carolina State University developed a new high-throughput automated testing system that deposits multiple samples on the same substrate, thus saving time and energy.

While some studies have demonstrated that electric fields and light exposure can affect the motion of dislocations in ceramics, the principal driving force of motion in these cases was mechanical stress. Now, an international group of researchers showed dislocation motion in a single-crystalline zinc sulfide can be controlled using only an external electric field.

Balancing cost and quality is an important consideration for manufacturers and researchers looking to commercialize their innovations. Researchers in Germany explored the tradeoffs that come with creating all-oxide ceramic matrix composites from fiber bundles with higher filament counts.

Instead of open-pit mines, tailings may become the primary source of feldspar and quartz in the future if the minerals can be selectively extracted from the waste. Researchers in China showed that hydroxypropyl starch can improve the flotation separation of feldspar and quartz.

White phosphorus is a synthetic form of phosphorus used to produce many commodity chemicals. But the conventional process for producing white phosphorus has a high carbon footprint. Researchers at Massachusetts Institute of Technology developed a molten salt synthesis process for white phosphorus production that is more cost effective and environmentally friendly.
