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 mem...
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 ...
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...
Then, as single-point techniques for non-invasive analysis, FORS, reflectance FTIR spectroscopy, Raman spectroscopy and spectrofluorimetry with visible excitation were used to achieve a complete characterization of the coloring materials used by the artist. In particular, for the fluorescence measurements...
OCT: Optical Coherence Tomography, PS-OCT: Polarization-sensitive OCT, SDOCT: Spectral Domain OCT, PAM: Photoacoustic Microscopy, SHG: Second-harmonic generation, THG: Third-harmonic generation, SRS: Stimulated Raman Scattering, CARS: Coherence Anti-Stokes Raman Spectroscopy, IR: Infrared, NIR: Near...
In fact, a typical phase diagram of these multiblock copolymers in aqueous solution displayed a critical gel concentration (CGC) and a phase-transition temperature, which were mainly determined by these parameters. Phase separation-induced gelation mechanism was advanced to explain the thermoreversible ...
