A simple, rapid, accurate, precise, and economic Spectrophotometric method for formulated microspheres dosage form has been developed. Capecitabine shows absorbance maximum at different wavelength in different solvents, so absorbance was measured and the same wavelengths used for the estimation of Capecitabine in respective solvents. Capecitabine obey the beer lamberts’ law. Method is validated...

In this paper, the wavelength modulation spectroscopy (WMS) technique is modified and used for measuring methane with large absorbance. WMS has been frequently gas measurement relies on linear relationship between second harmonic amplitude volume concentration however, conventional only applicable gases whose absorbance much smaller than 1, which because of first-order approximation to Lambert-...

Absorbance is often used for simulations or validation of process parameters powder-based laser materials processing. In this work, the absorbance 39 metal powders additive manufacturing determined at 20 wavelengths. Different grain sizes and aging states for: steels, aluminum alloys, titanium Nitinol, high entropy alloy, chromium, copper, brass iron ore were analyzed. For purpose, spectrum was...

BACKGROUND AND AIMS Epidermal phenolic compounds (mainly flavonoids) constitute a vital screen that protects the leaf from damage by natural ultraviolet (UV) radiation. The effectiveness of epidermal UV-screening depends on leaf anatomy, the content of UV-screening compounds and their spatial uniformity over the leaf area. To investigate in vivo the spatial pattern of the epidermal UV-screen du...
