The esterification reaction between wood fibers and maleated polypropylenes was investigated. The reaction was conducted in a reactor in the presence of xylene used as a solvent and sodium hypophosphite as catalyst. The reaction between wood fibers and pure maleic anhydride was also investigated. Th

Infrared reflection spectra of GaAs with surface gratings contain the signature of surface phonon polaritons (SPPs) and Wood anomalies. For grating periods comparable with the vacuum wavelength of the SPPs, small gaps appear to be present in the SPP dispersion. For certain polarization conditions, t
## Abstract We studied wood polymers in their native composite structure using mechanically isolated single spruce (__Picea abies__ [L.] Karst.) fibers. Dichroic infrared spectra of fibers placed in a customβbuilt microfluidic cuvette were acquired in air, in liquid (heavy) water, and in liquid dim
Near-infrared spectroscopy offers tremendous advantages for pharmaceutical manufacturing as a fast and nondestructive method of quantitative and qualitative analysis. Content uniformity (end-product analytics) and process analytics are two important applications of the method. Diffuse reflection (DR
