Surface Properties of Vitreous Fibers
Journal of Colloid and Interface Science, 2000 The surface properties of various vitreous fibers, suspected to be toxic to humans and animals, were investigated by means of paramagnetic labels covalently linked to the surface. Computer-aided analysis of the electron paramagnetic resonance (EPR) spectra provided structural and dynamic information on the label and its environment.
