It was found that the Raman peaks of BaTiO3 shift toward higher frequency(blue shift), instead of the red shift generally observed when the particle size is reduced, and the linewidth increases when the grain is coated. Meanwhile, we found that different coating show different amount of Raman...
All pixels with derivation values > 0.4 or <−0.4 (meaning > |0.4 | ) were counted and normalized for total number of pixels assigned to the specific cluster along the trajectory. Statistical significance was calculated by Welch Two Sample t-test with R. To analyze reproducibility...
In ferroelectric materials, phase transitions are often displacive, meaning that they involve the displacement of atoms or ions. Such transitions are underlined by the large frequency variation of an optical phonon, named “soft mode”, which tends to zero (i.e., “softens”) by approaching th...
To assess this with Raman spectroscopy, it is necessary to build up a chemometric model to define the meaning of “authentic” for the particular food in question by using a sample set that represents the widest variety of bona fide product possible, as well as a representative range of...
Intensity is renormalized and our computational wavelength of VGInt is blue-shifted by 3629 cm−1−1 (0.45 eV); VGInt considering the effects of 6H22O is blue-shifted by 4839 cm−1−1 (0.6 eV) for CAM-B3LYP (top); VGInt are blue-shifted by 3629 cm−1−1 (0.45 eV); ...
The Surface-Enhanced Raman Scattering (SERS) occurs due to the coupling of two phenomena: (1) (Spontaneous) Raman Scattering—vibrational/phonon modes mix with an optical excitation, leading to radiation with a frequency shift, and (2) Surface Enhancement—Localized Surface Plasmons (LSP) and/or...
Meaning that you must know if the laser is single transverse mode, single longitudinal mode, or both. Get all the information you need in this article: “What is Single Longitudinal Mode?” Get more information from our Lasers 101, Blogs, Whitepapers, FAQs, and Press Release pages in our ...
The STM32F103 doesn’t have 32-bit timers, meaning the integration time is quite limited. Even with the slowest MCLK supported by the CCD it’s: tint (max) = 2¹⁶ / MCLK = 2¹⁶ / 800 kHz = 82 ms UART isn’t that convenient without the nucleo-board’s built-in USB->UART...
As used in the description and throughout the claims that follow, the meaning of “a”, “an”, and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description and throughout the claims that follow, the meaning of “in” includes “in...
