Green Synthesis of Zinc Oxide Nanoparticles
Nano-sized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Aloe vera. The structures, morphology, optical properties, surface area and thermal behavior of these fabricated ZnO nanoparticles were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Ultravioletvisible spectroscopy (UV-vis), Photoluminescence (PL)/flourescence spectro...
متن کاملTHE THEORY OF PHOTOTHERMAL LENSING SPECTROSCOPY
A general theoretical description of dual-beam photothermallensing spectroscopy is given. The results are valid for most general conditions, that is, for flowing as well as stationary media, for optically thick as well as optically thin media, and also for any transverse modes of incident pump beams
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملSpectroscopy.
In this report we present preliminary results in search for the H3O + spectra in the first OH stretching overtone region. At least 30 absorption lines of H3O + were found in near infrared region 6900 to 6960 cm using a very sensitive time resolved continuous wave cavity ringdown spectrometer (cw-CRDS) with concentration modulation. H3O + ions were produced in pulsed microwave discharge in He/H2...
