Photographic film is a transparent plastic coated with a gelatinous film containing a silver salt, usually AgBr. When the film is exposed to light, individual photons absorbed by the Ag ions cause an electron-transfer reaction that produces neutral silver atoms ... [Pg.1476]

FIGURE 6.8 Three force curves taken at locations of a gelatin film thickness of 150 nm (curve A), 410 nm (curve B), and 1.15 pm (curve C). At high forces, the force curves are steeper for small thicknesses because the cantilever deflection is influenced by the underlying stiff substrate at these small film thicknesses. For comparing the slopes more easily, the curves are shifted such that their points of contact coincide. Reprinted with permission from Domke and Radmacher (1998). [Pg.215]

All liquids used for filling must flow by gravity at a temperature of 35°C or less. The sealing temperature of gelatin films is 37 40° C. [Pg.375]

The photochemistry of four triphenylmethane acid dyes was studied in poly(vinyl alcohol), methylcellulose and gelatin films. These model systems were chosen with a view to elucidating the complex free-radical reactions taking place in the heterogeneous dyed wool/ water/air system on exposure to UV radiation. The dye fading mechanism seems to involve an excited triplet state of the dye molecule [ 164] The rate of fading is governed by ... [Pg.160]

Adding sizing to impart resistance to penetration by liquids. Most sizing is a soap or wax emulsion precipitated by the alum. This produces a gelatinous film on the fiber and a hardened surface. [Pg.408]

Direct development by sulfite ion does not take place, probably because the rate of reduction of silver ions by the sulfite is much smaller than the rate of solution of the silver halide (see Section YI of this chapter). The writer has obtained physical development, however, with a solution of silver nitrate and sodium sulfite. A specially hardened gelatin film which was able to withstand the action of the solution at 70° for 40 minutes was used. The developing solution contained 1.7 g. silver nitrate and 13 g. sodium sulfite per liter. Fog formation was relatively high, as might be expected. [Pg.121]

Polymer solids also work as a carrier of photochemical reaction components. The irradiation of a cellulose paper after adsorbing EDTA, Ru(bpy)3 and MV2+ induced rapid formation of MV4 in the solid phase (Table 2) 45,48). The quenching experiments showed that a photoinduced electron relay of EDTA Ru(bpy)2 - —> MV2+occurs in the solid phase just like in the solution. In this reaction the main path for the MV4 formation is through Ru(bpy)2, and the rate of direct reduction of MV2 by cellulose molecule is very small. Such an electron relay occurred also in a gelatine film 47). [Pg.23]

Individual non-volatile solvents vary in their capacity for dissolving nitrocellulose. The type of nitrocellulose dissolved is also a factor to be considered. Marqueyrol and Florentin [34] report the following figures which denote the amount of solvent required to obtain a uniform gelatinous film (Table 184). [Pg.645]

Shankoff used thin gelatin films ( 1 ym) and discovered that a new development process gave vastly improved holograms. The film is washed in water and then immersed in isopropyl alcohol. This second step causes rapid dehydration of the water-swollen film Which shrinks and forms microscopic cracks in the uncross-linked regions. The result is a substantially increased... [Pg.264]

Irradiation of gelatine capsules may not only result in photodegradation of the drug but may also affect the bioavailability of the drug. Irradiated gelatine films showed a decrease of their water vapor transmission. Even though this effect did not occur with indomethacin capsules, long-term irradiation resulted in increased dissolution rates (42). [Pg.335]
