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.
Recently, the research team led by prof. KONG Lingtao at Institute of Solid State Physics, Hefei Institutes of Physical Science successfully prepared a type of hollow amorphous Co/C composites for activating H2O2 to generate singlet oxygen, achieving selective elimination of oxytetracycline (OTC) in complicated water matrices. The relevant results was published in Chemical Engineering Journal.
The Mid-infrared lasers (MIR) with high peak power and high repetition rate operating in the range of 2.7~3 μm have important application in laser surgery and optical parametric oscillator (OPO).
