An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee-ring effect." As a ...
A multinational research team, including engineers from the University of Cambridge and Zhejiang University, has developed a breakthrough in miniaturized spectrometer technology that could dramatically expand the accessibility ...
A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The platform created by the researchers enables the formation and dynamic tuning of photonic crystals with ...
Scientists at the University of Oxford have unveiled a pioneering method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, published in close collaboration with Ludwig-Maximilian ...
Infrared optoelectronic functional materials are essential for applications in lasers, photodetectors, and infrared imaging, forming the technological backbone of modern optoelectronics. Traditionally, the development of ...
The Field Museum in Chicago and the Foundation for Scientific Advancement reported that sediment-encased maturation of pine resin produces a hardened, translucent substance that closely mimics natural copal and amber in appearance, ...
Long-wave infrared birefringent crystals are essential materials in infrared optical applications in fields such as infrared imaging, laser technology, and optical communications. Due to limitations in birefringence, infrared ...
Birefringent crystalline materials are essential in advanced optical technologies such as isolators and modulators due to their ability to manipulate light polarization. However, designing high-performance birefringent materials ...
A study led by the University of Portsmouth has achieved unprecedented precision in detecting tiny shifts in light displacements at the nanoscale. This is relevant in the characterization of birefringent materials and in ...
The ultrafast dynamics and interactions of electrons in molecules and solids have long remained hidden from direct observation. For some time now, it has been possible to study these quantum-physical processes—for example, ...
