An optical coating like no other
For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings on tinted eyeglasses.....»»
Optical invention mirrors the image processing power of a human eye
On a cold, sunny day, you're driving on a rural road, surrounded by snow-covered fields. In an instant, your eyes process the scene, picking out individual objects to focus on—a stop sign, a barn—while the rest of the scene blurs in the periphery.....»»
New AI tool discovers realistic "metamaterials" with unusual properties
A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue—these extraordinary objects are already made from "metamaterials." Researchers from TU Delft have now developed an AI tool that not only can discove.....»»
Understanding the chemical communication between cells
Like the people they make up, cells communicate by bumping into one another and exchanging handshakes. Unlike people, cells perform these handshakes using the diverse range of sugar molecules coating their surface like trees covering a landscape. Han.....»»
A novel micrometer-thick porous coating with unparalleled biomarker detection abilities
Aging populations and the tendency to lead a more sedentary lifestyle in many parts of the world are thought to dramatically increase the number of people living with multiple chronic conditions. Moreover, climate change, as well as shifting patterns.....»»
Submonolayer biolasers: Lower gain, higher sensitivity
