Based on widely used axial strain measurement method of Kevlar single fiber, an original theoretical model and measurement principle of application of micro-Raman spectroscopy to multi-fiber strains in a fiber bundle were established. The relationship between the nominal Raman shift of fiber bundle ...
(Color online) The principle and application of micro- and nano-random lasers. (a) Concept comparison between conventional lasers and random lasers. (b) Threshold curves of the random lasing spectra of breast cells in normal (MCF-10A) and cancerous (MCF-7, MDA-MD-231) states. Reproduced ...
For failure and defect analysis, FTIR and Raman spectroscopy are powerful tools in polymer, electronic, pharmaceutical, automotive, and papermaking industries.
Raman spectroscopy, in principle, is an excellent technique for the study of molecular species developed on metal surfaces during electrochemical investigations. However, the use of the more common laser wavelengths such as the 514.5-nm line results in spectra of less than optimal intensity, ...
Pump-probe spectroscopy presents a viable solution, which can be used to observe electron dynamics during a chemical reaction. In fact, femtosecond pulse durations are shorter than many physical/chemical characteristic times, which permits manipulating, adjusting, or interfering with electron dynamics. ...

Structure of the multilayered actuator and principle of image charge stepping actuation. [Adapted from S. Egawa and Higuchi, 1990.] IV.C.2 Piezoelectric Actuators The piezoelectric effect is also applicable in a microdynamic system. A microfabricated cantilever 1 mm beam of silicon nitride ...
The analysis of MNPs in various environmental samples is carried out using methods such as FT–IR/microFTIR, Raman/micro-Raman spectroscopy, TEM/SEM, and GC–MS (Fig. 2) (Wu et al., 2023). Each of these methods has considerable advantages in addition to their potential limitations in rout...
In principle, the resolution of the DCS system could be adjusted in steps from GHz to 22 GHz, making it possible to optimize resolution and SNR depending upon the characteristics of the gas sample. The GHz DCS system also enabled fast and precise measurement of the absorbance spectrum. ...
resulting in the generation of light under electron exposure. By performing CL spectroscopy, making sure to remain in the regime where the morphology of the particles is intact, we have performed proof of principle measurements to characterise a variety of micro and nanoplastic materials, for instanc...
