At the National Synchrotron Radiation Research Center, a small/wide-angle X-ray scattering (SAXS/WAXS) instrument has been installed at BL23A beamline with superconducting wiggler insertion device. This is equipped double Si(111) crystal and Mo/B 4 C multilayer monochromators, an Si-based plane mirror that can selectively deflect beam downwards for grazing-incidence SAXS (GISAXS) studies of air–liquid or liquid–liquid interfaces. The SAXS/WAXS instrument, situated in experimental hutch,...

In this work, both advantages of sodium-ion batteries and dual-ion have been combined in an innovated sodium-ion-based battery (SDI) system using a Na metal film as anode freestanding meso-carbon microbead (FS-MCMB) cathode. FS-MCMB SDI exhibited superior working performance with the specific capacity 83.6 mAh/g remarkable long-term stability over 300 cycles. The advantage high mass density loading range 2–7.5 mg cm–2, which was equal to comparable 78–83 mAh/g. electrochemical impedance...
Intensive energy demand urges state-of-the-art rechargeable batteries. Rechargeable aluminum-ion batteries (AIBs) are promising candidates with suitable cathode materials. Owing to high abundance of carbon, hydrogen, and oxygen rich chemistry organics (structural diversity flexibility), small organic molecules good choices as the electrode materials for AIB. Herein, a series small-molecule quinone derivatives (SMQD) AIB were investigated. Nonetheless, dissolution into liquid electrolytes...
Selective electrocatalytic NH<sub>3</sub>synthesis using Li intercalated 1T-MoS<sub>2</sub>.
A facile synthesis route for the preparation of N-doped ordered mesoporous carbons (NOMCs) containing well-dispersed, highly stable Pt nanoparticles (NPs) is reported. The these mesostructured Pt-NOMC materials invokes pyrolysis co-fed carbon sources and precursors in 3-[2-(2-aminoethylamino)ethylamino]propyl-functionalized SBA-15 silicas, which served simultaneously as N hard templates. It was found that dispersion NPs increases with increasing content nanocomposites, leading to higher...
A novel surface-enhanced Raman scattering (SERS) sensing system which operates by the self-assembly of Ag nanoparticles (AgNPs) onto nanocomposite AgNPs and graphene oxide (AgNP-GO) in presence two complementary DNAs has been developed. In this system, AgNP-GO serves as a SERS-active substrate. The with modification non-fluorescent 4-mercaptobenzoic acid (4-MBA) act highly efficient probes for DNA hybridization.
