  • It has been suggested that the extreme states of matter generated by high-intensity lasers could allow conditions similar to those in the vicinity of black holes to be studied in the lab. The observation of striking similarities between the X-ray spectra emitted by a laser-driven laboratory plasma and those measured from two high-mass binary star systems suggests such potential has been realized.

  • Autologous skin flap transplantation is a common method to repair complex soft tissue defects. Here the authors develop a hydrogel patch that releases carbon monoxide and nitric oxide gases on demand, to afford a timely blood supply for skin flap transplantation during surgery, just improving the incidence of distal necrosis of the flap and reducing long-term functional loss.

  • The fluorescent carbon nanoparticles were grafted with the copolymers of N-isopropylacrylamide and spiropyran (f-CNP-g-poly(NIPAM-co-SP)), which have dual responses to light and temperature stimuli when they are in an aqueous solution. The blue-green and red fluorescence of the f-CNP-g-poly(NIPAM-co-SP) nanocomposites dissolved in water could be reversibly switched under UV and visible light stimuli. Meanwhile, when the temperature increased from room temperature (20 °C) to 38 °C, the blue-green fluorescence intensity decreased, the red fluorescence intensity increased, and the average hydrodynamic diameter of the f-CNP-g-poly(NIPAM-co-SP) nanocomposites increased due to aggregation.
