Figure Lengend Snippet: Characterization of WPU-Cur. (a) FTIR spectra of WPU-Cur and WPU-E. The peak at 1509 cm –1 is related to curcumin in WPU-Cur. (b) Particle size distribution of WPU-Cur. (c) ζ potential of WPU-Cur. (d) Loading efficiency of WPU-Cur, and the curcumin concentration versus storage time, at room temperature, pH = 7.8. (e) Accumulative released curcumin curve of WPU-Cur and the fitted curve of EPE40-Cur and PEP35-Cur according to the Gallagher–Corrigan model.

Article Snippet: FTIR spectra were recorded on a PerkinElmer Spotlight 200i spectrometer in attenuated total reflection (ATR) mode.

Figure Lengend Snippet: FTIR spectra of CDs from CA, glucose, and soot.

Article Snippet: To study the composition of the functional groups of the CDs, infrared spectra (IR) were measured on an FTS 7000 IR-Fourier spectrometer (Varian, Palo Alto, CA, USA) and on a Spotlight 200i FTIR Microscopy System spectrometer (Perkin Elmer, Waltham, MA, USA) in the wavelength range of 4200–400 cm −1 .

Figure Lengend Snippet: Fourier transform infrared spectra (4000–650 cm −1 ) of ( a ) PS, ( b ) PA, ( c ) PE, and ( d ) PET MPs after photo-irradiation for 0, 7, and 14 d. The number of samples for the repeated experiments is n = 3.

Article Snippet: To evaluate the possible surface changes of MPs after photoaging, four types of MPs were measured in the wavelength range 4000–650 cm −1 using Fourier transform infrared microscopy spectroscopy (FTIR, Spotlight 200i, PerkinElmer, OH, USA) for both pristine MPs and differently photoaged MPs.
