Bright colors produced by laser heating

Most of the colors on today's paper and fabric are made using dyes or pigments. But colors can also be produced by modifying a material's surface at the nanoscale, causing the surface to reflect or scatter different frequencies ...

Deep learning democratizes nano-scale imaging

Many problems in physical and biological sciences as well as engineering rely on our ability to monitor objects or processes at nano-scale, and fluorescence microscopy has been used for decades as one of our most useful information ...

New traffic rules in 'Graphene City'

In the drive to find new ways to extend electronics beyond the use of silicon, physicists are experimenting with other properties of electrons, beyond charge. In work published today (Dec 7) in the journal Science, a team ...

Coherent electron trajectory control in graphene

Electronic systems using light waves instead of voltage signals is advantageous, as electromagnetic light waves oscillate at petaherz frequency. This means that future computers could operate at speeds 1 million times faster ...

Solving mazes with single-molecule DNA navigators

The field of intelligent nanorobotics is based on the great promise of molecular devices with information processing capabilities. In a new study that supports the trend of DNA-based information carriers, scientists have ...

Hybrid nanoantenna designed to manipulate visible light

A nanoscale optical antenna developed by researchers at A*STAR allows the manipulation of visible light waves on the scale of microchips. Such nanoantennae may enable the development of high-resolution imaging systems in ...

Detecting light in a different dimension

Scientists from the Center for Functional Nanomaterials (CFN)—a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory—have dramatically improved the response of graphene to ...

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Nanoplatelets improve LCD and LED screens

Researchers at the Physical and Analytical Chemistry department of the Universitat Jaume I (UJI) of Castellón, Spain, have taken part in the design of semiconductor nanoplatelets with a broadened range of colours to improve ...

A new approach to liquid-repelling surfaces

"Omniphobic" might sound like a way to describe someone who is afraid of everything, but it actually refers to a special type of surface that repels virtually any liquid. Such surfaces could potentially be used in everything ...

Flexy, flat and functional magnets

In the nanoworld, magnetism has proven to be truly surprising. Magnetic 2-D materials just a few atoms thick could provide a substrate for ever-smaller post-silicon electronics. An international research team led by Park ...

Tiny light detectors work like gecko ears

Geckos and many other animals have heads that are too small to triangulate the location of noises the way we do, with widely spaced ears. Instead, they have a tiny tunnel through their heads that measures the way incoming ...

Novel quantum dots enhance cell imaging

A team of researchers from the University of Illinois at Urbana-Champaign and Mayo Clinic have engineered a new type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is ...
