The use of gas sensors in detecting, monitoring, and evaluating combustion-related toxic and exhaust gases has attracted much interest. This technique finds practical application at both industrial and domestic levels as a tool for environmental protection and energy-saving.
HALIFAX, NS / ACCESSWIRE / May 31, 2022 / Meta Materials Inc. ("META®") (NASDAQ:MMAT)(FSE:MMAT), a developer of high-performance functional materials and nanocomposites, and PPG (NYSE:PPG) (together with
Staring through a microscope at samples of material for hours on end, attempting to locate monolayers, is one of the most laborious and intimidating tasks for undergraduate assistants in university research laboratories.
Metalenses are flat lenses that use metasurfaces to focus light. The metasurfaces are a series of artificial antennae that manipulate the optical response of the incident light, including its amplitude phase and polarization.
For their distant detection, minimum invasion, tolerance to electromagnetic interferences, and excellent resolution, optical-based sensors provide appealing alternatives in temperature monitoring for biological diagnostics. This article will look at a recent study published in Light: Science & Applications.
