A team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has developed the first flat lens for immersion microscopy. This lens, which can be designed for any liquid, may provide ...
The concept of a perfect lens that can produce immaculate and flawless images has been the Holy Grail of lens makers for centuries. In 1873, a German physicist and optical scientist by the name of Ernst Abbe discovered the ...
Despite a surge in solar cell R&D in recent years involving emerging materials such as organics and perovskites, the solar cell industry continues to favor inorganic crystalline silicon photovoltaics. While thin-film solar ...
Korean researchers are improving the fabrication of transistor-based biosensors by using silicon nanowires on their surface.
(Phys.org)—Scientists have developed a method for imprinting tiny yet complex 3-D structures on the tip of an optical fiber, whose 125-µm diameter is roughly the thickness of a human hair. The 3-D optical structures can ...
One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife.
A team of Korean researchers, affiliated with UNIST has recently pioneered in developing a new type of multilayered (Au NPs/TiO2/Au) photoelectrode that boosts the ability of solar water-splitting to produce hydrogen. According ...
Throw away the detergent and forgo the elbow grease: pesky proteins can now be removed from surfaces by simply exposing them to light, thanks to a reusable titania template developed by A*STAR researchers.
Lenses appear in all sorts of everyday objects, from prescription eyeglasses to cell-phone cameras. Typically, lenses rely on a curved shape to bend and focus light. But in the tight spaces inside consumer electronics and ...
A special class of glass materials known as chalcogenide glasses holds promise for speeding integration of photonic and electronic devices with functions as diverse as data transfer and chemical sensing. Juejun "JJ" Hu, the ...
