Second-harmonic generation is a nonlinear optical process that allows for the creation of low-power and compact light sources. Researchers in China discovered nanocrystal-in-glass composites exhibit a similar but different phenomenon called transverse second-harmonic generation that would allow for the creation of light sources with expanded capabilities.

MXenes hold potential as additives in ultrahigh-temperature ceramics to improve mechanical properties—but a gap in understanding the phase stability and transformation of MXenes at high temperatures limits this application. Researchers at Indiana University–Purdue University Indianapolis investigated these properties in titanium carbide MXenes.

Endless Frontier Act: Will applied research become a main focus for the National Science Foundation?
The National Science Foundation is one of the main federal funding sources for basic science research—but China’s significantly increased investments in scientific research has led some U.S. senators to propose a bill that would reorganize NSF to support more applied research. Learn more about this proposal in today’s CTT.

Designing better ballistic materials is more than a matter of finding the optimal combination of material properties—a deep understanding of the microstructure–damage relationships is required as well. A number of recent articles published in ACerS journals look to improve processing methods for fabricating dense, resilient ceramic components.

The 2D material borophene holds a lot of potential due to its flexibility, strength, and diverse atomic structure—but rapid oxidation of borophene in air makes application difficult. Researchers led by Northwestern University experimentally investigated the hydrogenation of borophene to see how well it stabilizes the material for practical use.

Basalt fiber is another material besides carbon and glass being considered to reinforce polymer composites. Researchers in Malaysia and Brazil compared the wear characteristics of epoxy composites reinforced with either basalt or glass fiber to understand the differences in their tribological performance.

Though gas ovens are considered more energy efficient than electric ovens, they still face challenges with dissipation of heat into the environment. Porous volumetric ceramic burners are a combustion technology that may improve heat transfer in gas ovens, and researchers in Germany investigated the technology’s heat transfer mechanisms to better illuminate its potential.
