Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles - also known as quantum systems - makes possible a wide range of technological applications, in fields which include magnetic field sensing, information processing, secure communication or ultra-precise time keeping.
Scanning lasers -- from barcode scanners at the supermarket to cameras on newer smartphones -- are an indispensable part of our daily lives, relying on lasers and detectors for pinpoint precision.
The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that could someday be used as cover panels for lamps, displays and laser devices.
Photodetectors have always paly the important role in the national economy and national defense field. The advanced photodetectors demand for the higher performance in response rate, broad spectrum, detectivity and other special functions like polarization detection and two-color detection.
Discovering and synthesizing symmetry-protected topological band degeneracies, including nodal points and nodal lines, is a rapidly growing frontier in the field of topological materials.
From microscopes to data transfer via optical fibres all the way to modern quantum technologies, light plays an important role in science and industry.
The continuing progress in miniaturization of silicon microelectronic and photonic devices is causing cooling of the device structures to become increasingly challenging.
At the latest since the Nobel Prize in Physics was awarded for research on graphene in 2010, 2D materials - nanosheets with atomic thickness - have been a hot topic in science.
How things deform and break is important for engineers, as it helps them choose and design what materials they're going to use for building things.
The photon jet effect was discovered in the early 2000s. The jet is an electromagnetic wave focused at the surface of a quartz glass microsphere, which is at lens focus.
