Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise focusing of light—only in one direction. This novel unidirectional focusing design uses structured ...
Quantum entanglement is a fundamental phenomenon in nature and one of the most intriguing aspects of quantum mechanics. It describes a correlation between two particles, such that measuring the properties of one instantly ...
The conversion of CO2 into e-fuels by light offers a sustainable solution to close the carbon cycle. Researchers at the Laboratory for Nanometallurgy have pioneered an innovative approach to plasmon-assisted catalytic CO2 ...
For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate. The optimized printing approach could enable super-resolution 3D direct laser writing (DLW) ...
Doubly periodic weaves—entangled structures with repeating patterns in two independent directions—pose a mathematical challenge. Originally conceived to model real-world structures, such as woven textiles and molecular ...
One of nature's most disliked creatures may very well unlock a breakthrough in disaster response. A multidisciplinary Purdue University research team is recreating mosquito antennae to better study their sensitivity to vibrations. ...
Electromagnetic metamaterials with negative physical parameters such as negative dielectric constant and negative magnetic permeability have attracted widespread attention in the academic community. In 2010, they were praised ...
For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the need for artificially manufactured metamaterials.
The idea of traveling through interstellar space using spacecraft propelled by ultrathin sails may sound like the stuff of sci-fi novels. But in fact, a program started in 2016 by Stephen Hawking and Yuri Milner, known as ...
Cornell scientists have developed a novel technique to transform symmetrical semiconductor particles into intricately twisted, spiral structures—or "chiral" materials—producing films with extraordinary light-bending properties.
