Researchers at the University of Sydney have developed a new type of radar that can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth ...

Structural colors result from interactions between light and nanostructures. Engineering structural colors is a promising, rapidly emerging research field. Compared with conventional painting ...

Nature may abhor a vacuum, but it sure loves structure. Complex, self-organized assemblies are found throughout the natural world, from double-helix DNA molecules to the photonic crystals that make ...

Metalenses -- flat surfaces that use nanostructures to focus light -- are poised to revolutionize everything from microscopy to cameras, sensors, and displays. But so far, most of the lenses have been ...

Scientists at Duke University have created the first invisibility cloak that perfectly hides centimeter-scale objects. While invisibility cloaks have been created before, they have all reflected some ...

Centimeter-scale color printing with pixelated F–P cavities. (a) The grayscale figure is obtained from the original drawing. (b) The white balanced photo of the centimeter scale color printing device.

However, large area membranes with sub-nanometer selective pores are much more sensitive to leakage through defects, necessitating scalable defect mitigation strategies, a number of which have been ...

A team of Chinese researchers have successfully grown the country's first centimeter-scale fish fillets in the lab using advanced technologies like stem cell isolation and tissue construction, ...
