High-precision tumor resection down to few-cell level guided by NIR-IIb molecular fluorescence imaging source:PNASSurgical removal of tumors has been performed to combat cancer for over a century by surgeons relying on visual inspection and experience to identify margins between malignant and healthy tissues. Herein, we present a rare-earth down-conversion nanoparticle–anti-CD105 conjugate for cancer targeting and a handheld imager capable of concurrent photographic imaging and fluorescence/luminescence imaging. An unprecedented tumor-to-muscle ratio was achieved by near-infrared-IIb (NIR...

source:Automotive NewsThe growing demand for electric vehicles is upending the automotive supply chain at a time when it was already stressed by the coronavirus pandemic, rising material prices and semiconductor shortages.The industry's push for new technologies and solutions is enormous, and R&D work is underway around the industry.During 2019 and 2020, the world's top 20 automakers alone spent nearly $94 billion on R&D as EV product plans take hold, according to a report last year by the financial firm BDO.Stellantis CEO Carlos Tavares has warned suppliers that they, too, mus...

source：optics.orgScientists from the University of Warsaw, the Military University of Technology, Poland, and the University of Southampton, UK, have developed a new type of tunable microlaser emitting two beams. “The beams are polarized circularly and directed at different angles,” explained Prof. Jacek Szczytko from Warsaw.This result was obtained by creating a “persistent-spin helix” on the surface of the microcavity. The achievement is described in Physical Review Applied.The scientists filled the optical microcavity with a liquid crystal doped with an organic laser dye. The microcavity co...
