Step right up for bigger 2-D sheets

Very small steps make a big difference to researchers who want to create large wafers of two-dimensional material.

What happened to the hyped nanomaterials?

Carbon-based nano materials such as graphene and carbon nanotubes were predicted to have a brilliant future when they were discovered. But quality problems curb the development of new products. The problem is that it is difficult ...

Putting photons in jail

A miniature prison for photons—that is the nanocavity discovered by scientists of the University of Twente. It is an extremely small cavity surrounded by an optical crystal, a structure of pores etched in two perpendicular ...

Near ground-state cooling of 2-D trapped ion crystals

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...

Sculpting stable structures in pure liquids

Oscillating flow and light pulses can be used to create reconfigurable architecture in liquid crystals. Materials scientists can carefully engineer concerted microfluidic flows and localized optothermal fields to achieve ...

How to freeze heat conduction

Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy.

Amazon's exit could scare off tech companies from New York

Amazon jilted New York City on Valentine's Day, scrapping plans to build a massive headquarters campus in Queens amid fierce opposition from politicians angry about nearly $3 billion in tax breaks and the company's anti-union ...
