The obtained spectra were compared. Recorded Raman spectra contained bands in the range of <900 cm−1 (first order) up to 2000 cm−1 (second order). The Raman spectra of the …
WebbMicro-Raman spectroscopy was performed at room temperature with a Jobin Yvon T64000 (Horiba, Kyoto, Japan) spectrometer in a backscattering confocal configuration. The excitation source was an Ar + laser at a wavelength of 488 nm, and laser power was controlled at 5 mW on the sample surface. Webb27 feb. 2024 · Introduction. When a β-particle (energetic electron from nuclear decay) enters a material its path can be deflected when it interacts with the nuclei of the material. The β-particles are oppositely charged to the positively charged nucleus and thus an attractive force exists between the two. The deflections that result are dependent on the ...

WebbOptical coherence tomography (OCT) is a powerful technology for rapid volumetric imaging in biomedicine. The bright field imaging approach of conventional OCT systems is based on the detection of directly backscattered light, thereby waiving the wealth of information contained in the angular scattering distribution. Here we demonstrate that the unique …
Webb12 apr. 2024 · Raman scattering is commonly used to quantify defects in s p 2 carbons, mostly based on the values of the double-resonant D-band intensity. It is well known that this peculiar band undergoes changes when the s p 2 carbon is polished. However, the physical process behind this phenomenon is unclear so far. kysbb.ssghosting.comWebbPhD Student - Development of Raman microscopy techniques for tissue imaging.
