The Solar Electron and Proton Telescope (SEPT) aboard the Solar Terrestrial Relations Observatory(STEREO) is designed to provide the three-dimensional distribution of energetic electrons and protons...doi:10.1007/s11207-018-1321-6Wraase, S.
核磁经典教程 Understanding NMR Spectroscopy Keeler_ch2.pdf,2 NMR and energy levels The picture that we use to understand most kinds of spectroscopy is that molecules have a set of energy levels and that the lines we see in spectra are due to transitions
electrochemical proton storage systems frequently use acidic aqueous solutions as electrolytes to avoid the environmental pollution caused by the toxic organic electrolytes. (iv) Safety, active metals (such as Li, Na, and K) and flammable organic solvents are...
NMR in combination with the first-principles calculation of liposil structure allowed the detailed investigation of the organic-inorganic interface in liposil. The 31P ssNMR study is shown in Fig. 5C left: the 31P proton-decoupled slow MAS (black) and static (red) echo spectra of DPPC ...
The distribution of different binding modes is also reflected in the lineshapes of the91Zr wideline NMR spectra (Fig.6d). They consist of at least four different quadrupolar shapes with non-axial symmetric coupling tensors and coupling constants (CQ) between 10 and 25 MHz. This proves a ma...
19 and calculated Si/Al ratios estimated based on the 29Si NMR spectra were included in Supplementary Table 4. The Si/Zr ratio of Zr/Beta was determined to be 199 by ICP-AES. Powder X-ray Diffraction (XRD) patterns were collected on a Bruker D8 Discover powder diffractometer with a Cu ...
The 1H NMR experiments were performed using an Agilent 400 MHz spectrometer equipped with 5 mm OneNMR probe. The measurements were performed at 25 °C. 1H NMR spectra of microwaxes were acquired using spectral width of 4807.69 Hz, relaxation delay of 5 s, 1000 repetitions and acquisition time...
HDL, particles of different sizes exhibit distinct NMR signal characteristics, enabling the differentiation of various HDL subclasses based on these signals. By analyzing NMR spectra, the diameter range of HDL particles can be determined, classifying HDL into large, medium, and small subclasses [102]...
Q.J. conceived the project, designed the experiments and proposed the HER/HOR mechanism. Q.S. conducted the electrochemical experiments and the data analysis in S.M.’s lab partly under his supervision. S.T. and J.J.G. conducted the NMR experiments and analysed the data. Q.S. helped ...
NH2-ICG is also supported by NMR studies. The two gem-dimethyl groups in cypate showed a singletat upfield [10] while they split into two singlets in NH2-ICG proton spectrum. Furthermore, the corre-sponding 1st, 3rd, 5th, and 7thvinyl protons of the heptamethine bridge showed a doublet...
