Driven by the rapid development of modern electronics in minimization, high integration and high-power density, tailored polymer films with high thermal conductivity and electrical insulation have made great progress. However, traditional approaches for enhancing thermal conductivity usually sacrifices processability, electrical insulation and mechanical flexibility of the polymer films.
NIR-induced photothermal therapy (PTT) has attracted much attention due to its non-invasive and convenient operation. However, several disadvantages are associated with the implementation of the reported second near-IR (NIR-II) responsive PTAs in the clinic. Magnetic nanoparticles (MNPs) just meet this demand, due to their good biocompatibility and unique magnetic properties. Therefore, it is of great scientific significance to explore a new magnetite nanostructure with NIR-II activation for imaging-guided combined cancer therapy.
Recently, Prof. WANG Zhenyang’s research group from Institute of Solid State Physics, Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), has made new progress in the large-area preparation of macroscopic thick three-dimensional (3D) porous graphene films. Researchers used high-energy e-beam as the energy source and took the advantages of the high kinetic energy and low reflection characteristics of e-beam to directly induce polyimide precursor into a 3D porous graphene crystal film with a thickness of up to 0.66 mm. Related research results were published in the journal Carbon.
Searching for layered materials that harbour chiral spin textures, such as skyrmions, chiral domain Walls is vital for further low-energy nanodevices, as those chiral spin textures are building blocks for topological spintronic devices and can be driven by ultra-low current density.
When HU Hao, a 26 years old PhD student majoring on biophysics, put on the caps and gowns, and is ready for the graduation ceremony, he knew it’s time to say goodbye to campus and embark on the next phase of journey.
