A team of ICFO researchers develops a new class of broadband solid state light emitter in the short-wave infrared that could be miniaturized, integrated with CMOS technology and used for many applications including food inspection, health or safety.
Scientists typically prefer to work with ordered systems. However, a diverse team of physicists and biophysicists from the University of Groningen found that individual light-harvesting nanotubes with disordered molecular structures still transport light energy in the same way. By combining spectroscopy, molecular dynamics simulations and theoretical physics, they discovered how disorder at the molecular level is effectively averaged out at the microscopic scale.
Researchers have registered the formation of silver nanoparticles in an ion-exchanged glass as a result of infrared laser irradiation. The research of current studies were published in the journal of Nanomaterials.
Biometric authentication, which uses unique anatomical features such as fingerprints or facial features to verify a person's identity, is increasingly replacing traditional passwords for accessing everything from smartphones to law enforcement systems.
Researchers have established a novel high-frequency laser facility at the University of Tokyo. The coherent extreme ultraviolet light source can reveal details of biological or physical samples with unprecedented clarity. It also allows for investigation of time-dependent phenomena such as ultrafast chemical reactions. Existing facilities for such investigations necessarily require enormous particle accelerators and are prohibitive to many researchers. This new facility should greatly improve access for a broad range of researchers.
Scientists led by the Institute of Industrial Science at the University of Tokyo used computer simulations to better understand the mechanical transition in glassy materials. They found that a system-wide network provides the backbone that gives glass its strength. This work may lead to advances in the production of stronger glass for smartphones and other applications.
Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon's ability to transfer momentum was used in a novel approach by scientists of the Max Born Institute, Uppsala University, and the European X-Ray Free-Electron Laser Facility to observe a fundamental process in the interaction of x-rays with atoms. The detailed experimental and theoretical results are reported in the journal Science.
The Hyperspectral Stripe Projector captures spectroscopic and 3D imaging data for applications like machine vision, crop monitoring, self-driving cars and corrosion detection.
Researchers at the National Institute of Standards and Technology (NIST) have devised and demonstrated a system that could dramatically increase the performance of communications networks while enabling record-low error rates in detecting even the faintest of signals.
The colloidal diamond could make light waves as useful as electrons in computing, and hold promise for a host of other applications. Researchers let by NYU Tandon Professor David Pine have devised a new process for the reliable self-assembly of colloids in a diamond formation that could lead to cheap, scalable fabrication of such structures.
