purpose: to determine factors that affect and predict final visual acuity, retinal attachment, and ocular survival after open-globe injuries. methods: one-hundred sixteen eyes with open globe injuries were evaluated longitudinally from september 2001to february 2004. age, sex, involved eye, best corrected visual acuity (bcva), afferent pupillary defect (apd), size and location of laceration, ca...
The structure and mechanical properties of bio-nanocomposite films made from poly(ethylene oxide) (PEO) that is physically cross-linked with silicate nanoparticles, Laponite, are investigated. Direction-dependent mechanical properties of the films are presented, and the effect of shear orientation during sample preparation on tensile strength and elongation is assessed. Repeated mechanical defo...
Here, we show that a poly(ethylene oxide) polymer can be physically cross-linked with silicate nanoparticles (Laponite) to yield highly extensible, bio-nanocomposite fibers that, upon pulling, stretch to extreme lengths and crystallize polymer chains. We find that both, nanometer structures and mechanical properties of the fibers respond to mechanical deformation by exhibiting strain-induced cr...
Sustainable and green materials have been studied in dye pigment productions to reduce their environment impacts from being produced applied. Although natural dyes are an excellent choice move agrowaste, some improvements must be made before they applied given poor fastness. One way of improving properties is adsorption into nanoclay structures give hybrid pigments. This work used tubular hallo...
