Annealing of the extruded membranes at 110 °C transformed the crystalline into amorphous PEO layers, as confirmed by IR nanospectroscopy, yielding a gas permeability close to that of the solvent-cast membranes. We thus attribute the dramatic gas reduction of the extruded membranes to their highly...
All compounds were characterized in solution using multinuclear NMR spectroscopy (1H, 13C{1H}, 31P{1H} and 71Ga) and in the solid state using FT-IR spectroscopy and X-ray crystal diffraction. The new Ga-phosphine salts resulted stable and highly soluble in aqueous solution at room ...

The phase diagram of the quasi-2D Ce(Ir,Rh)In5 system contains two distinct superconducting domes. By the thermal transport measurements in rotating magnet... Y Kasahara,T Iwasawa,Y Shimizu,... - 《Physical Review Letters》 被引量: 37发表: 2007年 ...
Membrane composition and structure were studied by Fourier-transform infrared spectroscopy, scanning electron and atomic force microscopies, and water contact angle measurements. The addition of PEG-PPG-PPG to the PPSU casting solution was found to increase the hydrophilicity of the membrane surface (...
Currently reported in situ techniques include in situ surface-enhanced infrared spectroscopy (IR), Raman spectroscopy, X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), online differential electrochemical mass spectrometry (DEMS), and electron microscopy (EM) [112,113]. Although these ...
(C) A schematic diagram of transcriptional variants of GPX4 involving regulation from distinct promoters associated with distinct exons. (D) Change in RNA levels of mitochondrial targeted GPX4 transcript variant (with exon 1a) and nuclear targeted GPX4 transcript variant (with exon 1b) after unbiased...
Fig. 7 represents a schematic diagram of the structural evolution of hard and soft domains during heating. At 30 °C, F1 is less-ordered paracrystalline, and F2 is orderly. What we have to bear in mind is that the hard and soft phase are bi-continuous networks. In the diagram, we emp...
Figure 3. 1H NMR spectra of (a) cardo-PES-QA and (b) cardo-PES-IM in DMSO-d6 at 25 °C. * indicates solvent peak and # indicates moisture peak. The cardo-PES-QA and cardo-PES-IM copolymers were also analyzed by FT-IR spectroscopy. The FT-IR spectra in Figure 4 show the ary...
Fourier transform infrared spectroscopy (FT-IR) was performed on a Nicolet iS10 infrared spectrometer (Thermo Scientific, Madision, WI, USA) with a scanning range of 400–4000 cm−1 and a resolution of 0.09 cm−1, the number of scans was 32 and the sample was prepared by a KBr plate...
