Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Boron and boron carbide by vapor deposition

Electrodeposition and Surface Treatment, 1974
Abstract Boron trichloride can be reduced by hydrogen at 1,300°C with a recovery of approximately 85% as elemental boron. The optimum H2 to BCl3 molar ratio was 30 under the test conditions used. No reaction between tungsten substrates and the boron deposits could be detected.
