The light supply (Xe lamp HPX-2000, Ocean Optics) was guided by an optical fiber with a 200-m core (Newport) and focused on the water-TFT interface via plano-convex (Thorlabs) and achromatic lenses (Newport); see Fig. six. All lenses had been placed at their confocal lengths. The longer wavelengths ( 700 nm) were cut by a Hot Mirror (Thorlabs) to prevent heating from the interfacial region. The reflected light was focused onto an optical fiber having a 1500 mm core (Thorlabs). The absorption spectra were recorded by a Maya 2000Pro (Ocean Optics). In situ parallel beam UV/Vis absorbance spectroscopy The spectrometer made use of was a USB 2000 Fiber Optic Spectrometer (Ocean Optics). The light source that was a DH-2000-BAL deuteriumhalogen (Ocean Optics) was guided through the optical fiber of 600 m in diameter (Ocean Optics, USA). The light beam was collimated using optical lenses (Thorlabs; focal length, 2 cm) just before and immediately after the transmission of your beam via the electrochemical cell. The light beam passed by means of the electrochemical cell slightly above the water-TFT interface, i.e., by means of the aqueous phase. w The interfacial Galvani prospective difference ( o ) was controlled using an Autolab PGSTAT204 potentiostat (Metrohm, Switzerland). Differential capacitance measurements AC voltammetry was performed within a four-electrode electrochemical cell. Differential capacitance was calculated from the interfacial admittance recorded working with an Autolab FRA32M module in mixture using the Autolab PGSTAT204 at a frequency of five Hz and root imply square amplitude of 5 mV. The scan path was from adverse toward much more positive potentials, from ca. -0.three to +0.55 V. Double potential step chronoamperometry DPSCA experiments had been performed inside a four-electrode electrochemical cell in conjunction with the in situ parallel beam UV/vis absorbance spectroscopy setup described vide supra. The first pow tential step was held at o = +0.four V for 10 s. The second possible w step was negative and held at o = -0.three V for ten s. This double possible step was repeated 300 instances, and one UV/vis spectrum was recorded inside every cycle. Confocal S1PR5 Agonist list fluorescence microscopy Samples were imaged on an ImageXpress Micro Confocal High-Content Imaging Method (Molecular Devices) with 20X S Plan Apo-objective. Confocal Raman spectroscopy Raman spectra had been collected making use of a Renishaw Invia Qontor confocal Raman spectrometer (excitation = 532 nm) in static mode (2400 grooves/mm). Due to vibrations on the liquid-liquid interface, and to retain a great focus throughout the entire scan, the static mode was preferred to acquire Raman spectra more than the synchroscan mode. Static mode allowed more quickly scan over the 650 to 1800 cm-1 region of interest. In typical, ten to 15 s was required to record a full Raman spectrum.Fig. 6. UV/vis-TIR experimental setup.
