Rapid, Microwave‐Assisted, and One‐Pot Synthesis of Magnetic Palladium–CoFe2O4–Graphene Composite Nanosheets and Their Applications as Recyclable Catalysts

26-Aug-2013 | Xiaofeng Lu, Liu Yang, Xiujie Bian, Danming Chao, Ce Wang, Particle & Particle Systems Characterization, 2013

Here, a microwave‐assisted approach has been demonstrated to rapidly prepare magnetic Pd–CoFe2O4–graphene (GE) composite nanosheets in ethylene glycol (EG) solvent. The generation of both Pd and CoFe2O4 nanoparticles is accompanied with the reduction process of graphene oxide (GO) by EG. The ...

Spectrometer for hard X‐ray free‐electron laser based on diffraction focusing

08-Feb-2013 | V. G. Kohn, O. Y. Gorobtsov, I. A. Vartanyants, Journal of Synchrotron Radiation, 2013

X‐ray free‐electron lasers (XFELs) generate sequences of ultra‐short spatially coherent pulses of X‐ray radiation. A diffraction focusing spectrometer (DFS), which is able to measure the whole energy spectrum of the radiation of a single XFEL pulse with an energy resolution of ΔE/E≃ 2 × 10−6, is ...
