Suppressing ambient oxidation of 2D materials—hydrogenation stabilizes borophene for practical use

By Lisa McDonald / March 19, 2021

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.

Rose-tinted contact lenses offer color vision management

By Lisa McDonald / March 5, 2021

People who have color vision deficiency see colors differently from others. Tinted glasses and contact lenses offer a way to manage the condition, but to date only the former option is reliably effective. Researchers developed a new type of tinted contact lens using gold nanoparticles that shows potential for commercial scale-up.

Fab-bow-lous synthesis: Researchers grow graphene nanoribbons for lower cost at higher yield

By Lisa McDonald / January 19, 2021

Graphene nanoribbons are a family of carbon allotropes that exhibit semiconducting properties promising for electronic applications. However, the conventional bottom-up synthesis method for graphene nanoribbons is a costly and low-yield process. Researchers led by the Moscow Institute of Physics and Technology developed an alternative method that is higher yield and lower cost.

Stretching the possibilities: Bendable single-crystalline diamonds hold potential for next-generation electronics

By Lisa McDonald / January 15, 2021

Diamonds have many desirable properties for application in electronic devices, but their rigid crystalline structure and brittle nature make it difficult to use diamonds for such a purpose. An international team of researchers led by City University of Hong Kong revealed in 2018 that diamonds are bendable on the nanoscale, and a follow-up paper published by them this month expands on that finding.

A new fabrication method takes root—researchers grow carbon nanotube forest of record length

By Lisa McDonald / November 20, 2020

Carbon nanotubes demonstrate much higher tensile strength than carbon fibers, but growing nanotubes in bulk while retaining this property is an obstacle that limits their commercial applications. Researchers in Japan developed a new fabrication method that could overcome the challenge of growing nanotubes in bulk.
