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.

Video: Battery-free computing restores retro gaming device

By Lisa McDonald / September 16, 2020

When restoring old technology, sometimes substituting modern alternatives for original parts can improve the classic design. Researchers at Northwestern University and Delft University of Technology in the Netherlands created a clone of the 8-bit Nintendo Game Boy using an energy-aware gaming platform.

I th‘ink’ we have a solution: Researchers explain mechanism behind uniform deposition of 2D materials for printed electronics

By Lisa McDonald / August 28, 2020

In 2017, an international team of researchers led by the University of Cambridge found a certain alcohol-based solvent allowed uniform deposition of inks containing 2D materials—a result important to advancing printed electronics. Now, the team has proposed a mechanism to explain their finding.

Video: Rising e-waste and a deficit of recycling

By Lisa McDonald / July 8, 2020

In 2017, a report on global e-waste predicted the amount of e-waste would increase to 52.2 million metric tonnes by 2021—but we already passed 53 million metric tonnes in 2019 alone, according to a new report released this month. Learn more about why e-waste amounts are surging, why current recycling systems are not keeping up, and what can be done to combat the problem.
