Jia and fellow researchers from Swinburne University of Technology recently teamed up with researchers from National University of Singapore, Rutgers University, University of Melbourne, and Monash University, to develop a method to generate precisely controlled graphene microbubbles on a glass surface using laser pulses.
The latest findings from the long-running CooperVision MiSight 1 day clinical study provide new insights about myopia management and the proven efficacy of the specially designed contact lens. Nearly one in four children's eyes originally fit with MiSight 1 day remain stable for myopia after six years.
Optical nanoantennas can convert propagating light to local fields. Scientists in China demonstrate that in the nanogap of a nanoantenna, a local-field hot spot can be turned into a cold spot, and the spectral dispersion of the local-field response can exhibit dynamically tunable Fano lineshapes with nearly vanishing Fano dips. The results may inspire diverse designs of local-field responses with novel spatial distributions, spectral dispersions and temporal dynamics, and expand the available toolbox for nano-optics.
Parity-time symmetry (PT), rooting in quantum field theory, are now shining in photonic systems. The implementation of PT symmetry usually requires spatially separated resonators to balance gain and loss between modes. Towards a more compact and economic way to realize PT symmetry, scientists invented a technique to manipulate light coupling with polarization diversity in a single fiber loop. The technique opens new avenues for the implementation of non-Hermitian photonic systems with increased functionalities.
Researchers say the breakthrough could lead to the production of thinner, lighter and more flexible solar panels that could be used to power more homes and be used in a wider range of products.
Researchers at The University of Tokyo studied a new mechanism of gelation using colloidal particles. By delaying the formation of gel networks after rigid-cluster formation, the final structure had less mechanical stress, leading to new gel production methods.
Scientists have shown that an algorithm added to image processing software can improve the resolution and accuracy of cryo-electron microscopes, which are one of the most crucial tools in microbiology and medical research.
The team of Professor Jinyang Liang, a specialist in ultrafast imaging at the Institut national de la recherche scientifique (INRS), in collaboration with an international team of researchers, has developed the fastest camera in the world capable of recording photons in the ultraviolet (UV) range in real time. This original research is featured on the front cover of the 10th issue of the journal Laser & Photonics Reviews.
Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics and particle sorting.
Terahertz light pulses change gene expression in stem cells, report researchers from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) and Tokai University in Japan in the journal Optics Letters. The findings come thanks to a new tool, with implications for stem cell research and regenerative therapy development.
