Monolayer silicon carbide achieved with both top-down and bottom-up synthesis methods

By Lisa McDonald / November 3, 2023

Theoretical studies have predicted that 2D silicon carbide in a stable honeycomb structure is possible, but experimentally achieving this material has proven difficult. Two recent papers successfully synthesized monolayer silicon carbide using top-down and bottom-up synthesis methods, respectively.

Nanoscale goldbeating: Ancient Egyptian technique adapted for fabricating 2D thin films

By Lisa McDonald / October 20, 2023

Two-dimensional thin films are often fabricated using bottom-up solution-based techniques, such as electrochemical deposition and atomic layer deposition. Now researchers have reported a top-down, solid-state method based on the age-old Egyptian craft of goldbeating that they say is generalizable to various metallic, polymeric, or ceramic nanoparticles.

Intricate sintering: Exploring the combined effect of multiple oxide inclusions on zirconia toughened alumina

By Lisa McDonald / October 17, 2023

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.

Reducing the environmental impacts of MXene synthesis: Life cycle assessment and production guide offer tips

By Lisa McDonald / September 15, 2023

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.

Compliant combustion: Nanocoating offers new way to control ‘runaway’ thermal reactions

By Lisa McDonald / September 8, 2023

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.

Optimized tape casting process creates lithium metazirconate thin films for use as solid-state electrolytes

By Lisa McDonald / August 29, 2023

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.

Foiled no more: A review of advancements in producing carbon nanotubes on flexible metal substrates

By Lisa McDonald / August 8, 2023

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.

High-throughput automated testing platform saves time and energy by placing dozens of samples on same substrate

By Lisa McDonald / July 28, 2023

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.

Hands-free defect engineering: Electric fields control motion of ceramic dislocations without need for mechanical loading

By Lisa McDonald / July 25, 2023

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.
