Electromagnetically induced transparency (EIT) is ‘tuned’ by two particles on the optical resonator. The different locations of particles control the propagation of light in either clockwise or counterclockwise directions, which switch on (upper configuration) or off (lower configuration) the interference of light, leading to controllable brightness (EIT) and darkness in […]

Physicists may have accidentally discovered a new state of matter. The possibilities are endless. Humans have been studying electric charge for thousands of years, and the results have shaped modern civilization. Our daily lives depend on electric lighting, smartphones, cars, and computers, in ways that the first individuals to take […]

A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period. Credit: Dr. Zhuangnan Li (UCL) While at the proof-of-concept stage, this new bendable graphene-based supercapacitor shows enormous potential as a portable power supply in several practical applications […]

Artist’s concept. A team of Australian scientists has discovered diamond can be bent and deformed, at the nanoscale at least. A team of Australian scientists has discovered diamond can be bent and deformed, creating possibilities for the design and engineering of new nanoscale devices. Diamond is prized by scientists and […]

Using femto-second lasers to etch metallic structures, University of Rochester Institute of Optics professor Chunlei Guo and his team have developed a technique that can be used to collect sunlight to heat etched metal surfaces, which can then power an electrical generator for solar power.

Infrared photographs of butterflies, where brightness correlates with the capability of radiative cooling. Credit: Nanfang Yu and Cheng-Chia Tsai/Columbia Engineering Researchers discover that butterflies have specialized behaviors and wing scales to protect the living parts of their wings; nanostructures found in the wing scales could inspire the design of radiative-cooling […]

A team of engineers demonstrated how they could — by using aqueous electrolytes instead of the typical organic electrolytes — assemble a substantially safer, cost-efficient battery that still performs well. Non-flammable, cost-efficient, and effective battery developed at Rensselaer Polytechnic Institute. As the lithium-ion batteries that power most phones, laptops, and […]
