An Application of Fourier Transform Infra-red (FT-IR) Microspectroscopy to the Study of Cigarette Manufacturing Defects


FT-IR microspectroscopy was used to investigate a common type of cigarette defect in which the filter separates from the tobacco rod. Infra-red imagings of the adhesive located at this junction on the tipping papers from both defective and acceptable cigarettes were obtained. A comparison of these data revealed that although adhesive was present in the seam area of the defective cigarettes, the amount of adhesive was significantly less and its distribution was not uniform.

Modification in surface properties of poly-allyl-diglycol-carbonate (CR-39) implanted by Au+ ions at different fluences

in the range from 5 × 10 13 ions/cm 2 to 5 × 10 15 ions/cm 2 . The structural and chemical alterations in CR-39 induced by ion implantation were analyzed by Raman and Fourier transform infrared (FT-IR) spectroscopy. The changes produced in the optical properties of implanted CR-39 were estimated using UV-Vis spectroscopy. The effect of varying fluence of metal ions on the electrical conductivity of implanted samples was explored. The examination of surface morphology of Au + ion implanted CR-39 was carried out by atomic force microscopy. The mechanism of

Structural and conductivity studies of LiNi0.5Mn0.5O2 cathode materials for lithium-ion batteries

unit cell lattice parameter was obtained by the least square fitting method from the d-spacing and (h k l) values. Further, the crystallite size of the sample was obtained from XRD pattern by applying Scherrer’s equation. The particle morphology of the powder was observed using a field effect scanning electron microscopy image taken from Carl Zeiss, EVOMA 15, Oxford Instruments, Inca Penta FETx3.JPG. Fourier transform infrared (FT-IR) spectra were obtained on a Shimadzu FT-IR-8900 spectrometer using a KBr pellet technique in the wave number range between 350 cm −1

Solvothermal synthesis and characterization of magnetic Fe3O4 nanoparticle by different sodium salt sources

water and ethanol, and dried at 70 °C in vacuum environment for 4 h. 2.3 Characterization Four available systems, XRF, XRD, SEM and FT-IR were used to characterize and compare the synthesized magnetite Fe 3 O 4 nanoparticles. XRD, Bruker D8 Advance diffractometer was used to collect XRD patterns at 30 kV and 20 mA, and CuKα radiation (λ = 0.1540598 nm). The particle sizes of synthesized nanoparticles were measured by FE-SEM (HITACHI S-4160). The crystallite size of the synthesized magnetic Fe 3 O 4 nanoparticles was estimated based on the Scherrer equation

Synthesis and characterization of polyimide thin films obtained by thermal evaporation and solid state reaction

150, 200 and 250 °C for 1 h in an air circulating oven. Fig. 1 Schematic illustration of the PVD chamber. Fig. 2 Two-step synthesis of polyimide. In the case of PI, the purpose of thermal treatment was to run polycondensation reactions in solid state till completion of the PI formation. As a consequence of these reactions a release of water and imidization took place. The final thickness of the films was 5±0.1 μm. 3 Results and discussion 3.1 FT-IR analysis FT-IR measurements have been performed for the films obtained at
