Rice lab's boron nitride composite could be u

Rice University scientists have found that a boron nitride nanocomposite interacts with light and heat in unexpected ways that could be useful for advanced technology applications.

Boron Nitride Nanocomposite Made for Innovative Applications

Similar to how the fragile No. 2 pencil’s core is made of carbon and how a cutting tool’s diamond is made of carbon, which is tougher than steel, boron nitride can occur in either soft or hard compounds.

Discovery of Piezoelectricity Across Phase Boundaries of 2D Materials

There's still plenty of room at the bottom to generate piezoelectricity. Engineers at Rice University and their colleagues are showing the way.

Materials theorist Boris Yakobson and graduate student Sunny Gupta at Rice's Brown School of Engineering describe the mechanism behind Rashba splitting, an effect seen in crystal compounds that can influence their electrons' "up" or "down" spin states, analogous to "on" or "off" in common transistors.

A little friction goes a long way toward stronger nanotube fibers

A computational model by materials theorist Boris Yakobson and his team at Rice's Brown School of Engineering establishes a universal scaling relationship between nanotube length and friction between them in a bundle, parameters that can be used to fine-tune fiber properties for strength.

Rice 'flashes' new 2D materials

 E-Mail IMAGE: Rice University scientists extended their technique to produce graphene in a flash to tailor the properties of 2D dichalcogenides molybdenum disulfide and tungsten disulfide, quickly turning them into metastable metallics... view more  Credit: Tour Group/Rice University HOUSTON - (Jan. 11, 2021) - Rice University scientists have extended their technique to produce graphene in a flash to tailor the properties of other 2D materials. The labs of chemist James Tour and materials theorist Boris Yakobson reported in the American Chemical Society's ACS Nano they have successfully "flashed" bulk amounts of 2D dichalcogenides, changing them from semiconductors to metallics. Such materials are valuable for electronics, catalysis and as lubricants, among other applications.
