  • It is no surprise to see the micro-Raman Group at Lille come forth with this timely publication to document the present state of Raman microscopy. A quarter century has passed since the early attempts at Raman microsampling when the field began to merge with, and complement, other microprobe techniques. In the late 1960s to the early '70s, it was mainly the electron beam methods that opened up the microscopic domain to instrumental analysis, aside from classical light microscopy.

  • Titanium Silicalite-1 (TS-1) with different contents of titanium were prepared according to the procedure as described in our report [1]. IR, Raman, XRD spectroscopies were used to identify the structure and in-framework, extra-framework titanium ions of TS-1. It is proven that Laser Raman spectroscopy is the most effective method to study the synthesis of TS-1.

  • Tungsten oxide film was deposited on ITO-coated glass by using RF magnetron sputtering method from WO3 ceramic target. Thin film preparation – process took place in Ar + O2 plasma. The dependence of tungsten oxide film structure on experiment conditions was investigated by X-ray diffraction (XRD) Raman spectroscopy. In this paper, we considered that the thickness of ITO layers about 150nm to 350nm clearly effects on the Raman and XRD spectrograms of WO3 films.

  • We used generalized two-dimensional NMR–NMR correlation to examine the effect of potassium ions on the conformation transition in silk fibroin to investigate the possibility that the fairly high K + ion content found in the distal end of silk-secreting ducts in the silkworms could have a bearing on natural formation of the silk fiber.

  • Physical measurement dimensions, such as temperature or pressure and tensile forces, can affect glass fibres and locally change the characteristics of light transmission in the fibre. As a result of the damping of the light in the quartz glass fibres through scattering, the location of an external physical effect can be determined so that the optical fibre can be employed as a linear sensor. Light scattering, also known as Raman scattering, occurs in the optical fibre.
