Smart metamaterials that sense and reprogram themselves

Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions. Engineering efforts can vary from passive to active forms to develop programmable metasurfaces using ...

Photosynthesis seen in a new light by rapid X-ray pulses

The ability to transform sunlight into energy is one of Nature's more remarkable feats. Scientists understand the basic process of photosynthesis, but many crucial details remain elusive, occurring at dimensions and fleeting ...

Blurry imaging limits clarified thanks to information technology

Although we're told a picture speaks a thousand words, that cliché seriously underestimates the value of a good image. Our understanding of how the world works is simplified by our ability to turn data into images. Imaging ...

Researchers convert 2-D images into 3-D using deep learning

A UCLA research team has devised a technique that extends the capabilities of fluorescence microscopy, which allows scientists to precisely label parts of living cells and tissue with dyes that glow under special lighting. ...

Intelligent metasurface imager and recognizer

The Internet of Things (IoT) and cyber physical systems have opened up possibilities for smart cities and smart homes, and are changing the way for people to live. In this smart era, it is increasingly demanded to remotely ...

Light-based 'tractor beam' assembles materials at the nanoscale

Modern construction is a precision endeavor. Builders must use components manufactured to meet specific standards—such as beams of a desired composition or rivets of a specific size. The building industry relies on manufacturers ...

New printer creates extremely realistic colorful holograms

Researchers have developed a new printer that produces digital 3-D holograms with an unprecedented level of detail and realistic color. The new printer could be used to make high-resolution color recreations of objects or ...

Researchers use 3-D printing to make glass optical fiber preform

Researchers have developed a way to use 3-D printing to create a preform that can be drawn into silica glass optical fibers, which form the backbone of the global telecommunications network. This new fabrication method could ...

Dielectric metasurfaces for next-generation holograms

Metasurfaces are optically thin metamaterials that can control the wavefront of light completely, although they are primarily used to control the phase of light. In a new report, Adam C. Overvig and colleagues in the departments ...

Surface functionalized microcavity boosts nonlinear optics

Silica optical microcavities are mainstay photonic devices, valued for their intrinsically ultra-low loss in the broadband spectra and mature fabrication processes, but unfortunately, they suffer from low second- and third-order ...

Compact depth sensor inspired by eyes of jumping spiders

For all our technological advances, nothing beats evolution when it comes to research and development. Take jumping spiders. These small arachnids have impressive depth perception despite their tiny brains, allowing them ...
