Uncontrolled hemorrhage often causes death during traumatic injuries and halting exsanguination topically is a challenge. Here, an efficient multimodal topical hemostat was developed by (i) ionically crosslinking chitosan and gelatin with sodium ...

MRS Proceedings, 1992
ABSTRACTThe aqueous polycondensation of resorcinol with formaldehyde proceeds through a sol-gel transition and results in the formation of highly crosslinked, transparent gels. If the solvent is simply evaporated from the pores of these gels, large capillary forces are exerted and a collapsed structure known as a xerogel is formed. In order to preserve

Optically active doped xerogel
Journal of Non-Crystalline Solids, 1992Abstract Using the sol-gel process, organic dye molecules have been trapped and individually encaged in a solid xerogel matrix. These doping molecules were aligned by a focussed femtosecond laser pulse, thus creating a local birefringence. The molecule alignment is permanent. An optical memory matrix is thus experimentally achieved.

Structure of Hybrid Colloid−Polymer Xerogels
Langmuir, 2004Crack-free monolithic gels were prepared from different mixtures of colloidal silica with a sol solution containing tetraethoxysilane, under powerful ultrasonic agitation (sonosol). Recently, information on the structure of these gels, inferred from N2 adsorption and mercury intrusion porosimetry, was presented.

Low-frequency dynamics in silica xerogels
Journal of Physics: Condensed Matter, 1996Brillouin and Raman experiments have been performed in hydrogenated silica sol - gel and vitreous silica samples made by sol - gel processes (xerogels) and by the melting powder method. The aim of this work has been the study of the low-frequency dynamics of sol - gel systems in comparison with that of amorphous silica.
