In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black ...
In a new paper published on May 1 in the journal Science Advances, researchers at Columbia Engineering used commercially available tabletop lasers to create tiny, atomically sharp nanostructures, or nanopatterns, in samples ...
A new study has been led by Prof. Xing-Hua Xia (State Key Lab of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University). While analyzing the infrared photoinduced force response ...
The NASA/ESA/CSA James Webb Space Telescope has captured the sharpest infrared images to date of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show a part of the iconic nebula ...
Near-infrared (NIR) light source, characterized by non-destructive and rapid detection, has a wide range of applications in diverse fields including food testing, safety, sensing, agricultural production and biomedicine. ...
A team at the University of Tokyo have constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its ...
Metalenses, nano-artificial structures capable of manipulating light, offer a technology that can significantly reduce the size and thickness of traditional optical components. Particularly effective in the near-infrared ...
For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can cause itching, inflammation ...
Recently, a research team led by Prof. Gao Minguang and Associate Prof. Li Xiangxian from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) has developed a spectral resolution enhancement method ...
Credit cards embedded chips, national mints printed watermarks, and high-profile locations installed retina scanners all for the same reason—to protect information. As attackers grow smarter, so must defense.
