Similar to how a radio antenna plucks a broadcast from the air and concentrates the energy into a song, individual atoms can collect and concentrate the energy of light into a strong, localized signal that researchers can ...
When chiral gold nanoparticles are irradiated with near-infrared femtosecond pulses, visible emission of luminescence is observed. In a study published in Advanced Optical Materials, this luminescence was found to yield high ...
A University of Houston researcher is reporting a new method to detect cancer which could make cancer detection as simple as taking a blood test. With a 98.7% accuracy rate, the method—which combines PANORAMA imaging with ...
Recently, a research group from Hefei Institutes of Â鶹ÒùÔºical Sciences of Chinese Academy of Sciences, developed an antielectric potential growth method for large-area preparation of Au-Ag heterodimer arrays. The prepared ...
Photonic computing, storage, and communication are the foundation for future photonic chips and all-optical neural networks. Nanoscale plasmons, with their ultrafast response speed and ultrasmall mode volume, play an important ...
Scientists have made a breakthrough in significantly improving the sharpness of X-ray imaging and potentially boosting the speeds at which X-ray scans can be processed. This lays the groundwork for both better medical imaging ...
An international research team led by Universität Hamburg, DESY, and Stanford University has developed a new approach to characterize the electric field of arbitrary plasmonic samples, like, for example, gold nanoparticles. ...
Traditional semiconductors such as Si, GaAs, and HgCdTe seem unable to meet the development trend of electronic devices that feature ultra-small volume, lightweight, and low power consumption. These limitations of traditional ...
The need for sustainable and environment-friendly solutions has accelerated the global demand for green and renewable technologies. In this regard, semiconductor photocatalysts have emerged as an attractive solution, owing ...
Perfect absorption arises from the strong interaction of valence electrons with light in a conducting material. Optical metamaterial is an effective approach to exploit the superior photon capture capability. Thus, the perfect ...
