“…Synchrotron Radiation Infrared Microscopy Characterization: The Fourier transform infrared (FTIR) spectroscopy measurements of polymer electrolyte membranes were carried out at the BL01B beamline of SSRF (Shanghai, China). [63] The beamline was equipped with a Nicolet 6700 Fourier transform infrared spectrometer and a Nicolet Continuum infrared microscope, in conjunction with a mercury cadmium telluride (MCT-A, 650 cm −1 cutoff) detector cooled with liquid nitrogen and IR radiation from a bending magnet source. The range of measurements was set from 4000 to 650 cm −1 at a spectral resolution of 4 cm −1 .…”

Elastomeric Electrolyte for High Capacity and Long‐Cycle‐Life Solid‐State Lithium Metal Battery

et al. 2023

High room‐temperature ionic conductivity and good compatibility with lithium metal and cathode materials are prerequisites for solid‐state electrolytes used in lithium metal batteries. Here, the solid‐state polymer electrolytes (SSPE) are prepared by combining the traditional two‐roll milling technology with interface wetting. The as‐prepared electrolytes consisting of elastomer matrix and high‐mole‐loading of LiTFSI salt show a high room temperature ionic conductivity of 4.6×10−4 S cm−1, a good electrochemical oxidation stability up to 5.08 V, and improved interface stability. These phenomena are rationalized with the formation of continuous ion conductive paths based on sophisticated structure characterization including synchrotron radiation Fourier‐transform infrared microscopy, wide‐ and small‐angle X‐ray scattering. Moreover, at room temperature, the Li||SSPE||LFP coin cell shows a high capacity (161.5 mAh g−1 at 0.1 C), long‐cycle‐life (retaining 50% capacity and 99.8% Coulombic efficiency after 2000 cycles), and good C‐rate compatibility up to 5 C. This study, therefore, provides a promising solid‐state electrolyte that meets both the electrochemical and mechanical requirements of practical lithium metal batteries.

“…Infrared spectrum data of the samples ranging from 4000-400 cm −1 were collected at the Shanghai Synchrotron Radiation Facility (SSRF) using a FTIR spectrometer (Thermo Nicolet 6700, Thermo Fisher Scientific Inc., Waltham, MA, USA) with a Nicolet continuum microscope (Thermo Nicolet IR200/100, Thermo Fisher Scientific Inc., Waltham, MA, USA) [11]. FTIR data were collected using line-scanning mode, which allowed us to collect infrared data line by line.…”

To study the dynamic changes of nutrient consumption and aflatoxin B1 (AFB1) accumulation in peanut kernels with fungal colonization, macro hyperspectral imaging technology combined with microscopic imaging was investigated. First, regression models to predict AFB1 contents from hyperspectral data ranging from 1000 to 2500 nm were developed and the results were compared before and after data normalization with Box-Cox transformation. The results indicated that the second-order derivative with a support vector regression (SVR) model using competitive adaptive reweighted sampling (CARS) achieved the best performance, with RC2 = 0.95 and RV2 = 0.93. Second, time-lapse microscopic images and spectroscopic data were captured and analyzed with scanning electron microscopy (SEM), transmission electron microscopy (TEM), and synchrotron radiation-Fourier transform infrared (SR-FTIR) microspectroscopy. The time-lapse data revealed the temporal patterns of nutrient loss and aflatoxin accumulation in peanut kernels. The combination of macro and micro imaging technologies proved to be an effective way to detect the interaction mechanism of toxigenic fungus infecting peanuts and to predict the accumulation of AFB1 quantitatively.

We performed Raman and infrared (IR) spectroscopy measurements of hydrogen at 295 K up to 280 GPa at an IR synchrotron facility of SSRF. To reach the highest pressure, hydrogen was loaded into toroidal diamond anvils with 40 m central culet. The intermolecular coupling has been determined by concomitant measurements of the IR and Raman vibron modes. In phase IV, we find that the intermolecular coupling is much stronger in the graphene (G) like layer of elongated molecules compared to the Br2 like layer of shortened molecules and it increases with pressure much faster in the G layer compared to the Br2 layer. These heterogeneous lattice dynamical properties are unique features of highly fluxional hydrogen phase IV.Dense hydrogen demonstrates a number of fascinating phenomena 1 , and theory predicts even more spectacular behaviors at higher pressures, which remained to be explored 2, 3 . Of particular interest is a behavior related to an increase of the kinetic energy and thus quantum atomic motion, which may lead to a change in the character of the chemical bonds 4 or even to a decline in the melting temperature, which can ultimately result in a liquid ground state 5, 6 . Hydrogen with the lightest atoms manifests the most suitable system to explore such effects. However, reaching the appropriate states requires very high pressures (⁓1 TPa), which remains technically challenging.Static high-pressure techniques have been recently progressing aggressively stimulated by scientific goals of better understanding materials under extremes (e.g. in planetary interiors), competition with dynamic compression techniques, and new advances in first principles calculations. High-pressure molecular hydrogen H2 is expected to transform to a metallic monatomic state at high pressures 7, 8 , but the route remained unclear. Until 2012, only three molecular phases of H2 have been widely recognized: plastic (fully orientationally disordered) hcp phase I and orientationally ordered phases II at low temperature and III at low temperature and high pressure. While phase II, possessing quantum ordering features 9, 10 , is unusual for
