Process visible

Since most of the dental applications employ a photoinitiated process (visible or ultraviolet light), the rate of initiation may be expressed as [92]... [Pg.185]

Colloiding of NC s with NG was followed microscopically using crystal violet base to make the process visible by ordinary light. With NC s lower than 11.4%N and higher than 12.6%N., only limited swelling occurred but with NC s betw 11.4 Sc 12.6%N gels were formed which could be seen to diffuse at a speed dependent on the vicosity) E)W.R.Moore, TransFaradSoc 43, 543-52 (1947) Sc CA 42, 3174... [Pg.185]

Irradiation also affects the course of more conventional separation processes. Visible and ultraviolet light have been found to affect plutonium solvent extraction by photochemical reduction of the plutonium (12). Although the results vary somewhat with the conditions, generally plutonium(VI) can be reduced to pluto-nium(IV), and plutonium(IV) to plutonium(III). The reduction appears to take place more readily if the uranyl ion is also present, possibly as a result of photochemical reduction of the uranyl ion and subsequent reduction of plutonium by uranium(IV). Light has also been found to break up the unextractable plutonium polymer that forms in solvent extraction systems (7b,c). The effect of vibrational excitation resulting from infrared laser irradiation has been studied for a number of heterogeneous processes, including solvent extraction (13). [Pg.262]

Estimation of Activation Energies of Consecutive Steps. The activation energies for the two distinct processes visible in Figs. 69 and 70 were extracted to obtain quantitative kinetic data on the thermal decomposition of Kapton. For this purpose, reaction rate constants are calculated for the imide signal... [Pg.185]

It is important that, before carrying out voltammetric experiments with analytes, the available potential window (range) is known and that there are no peaks of unwanted impurities in that range. The available potential window is determined by the currents of reduction/oxidation of the supporting electrolyte/solvent and, in the experiments, one should avoid entering potentials where these processes visibly occur. The products generated at the potential limits may interfere with the system under investigation and may affect the electrode surface. [Pg.332]

The need, because of the invisible nature of software and hence the difficulty of tracking of the activities which create software, to make the products of the software process visible and then to control the software process by tracking these now-visible intermediate and deliverable products. The visibility of the products of thought processes is commonly achieved through the use of modeling techniques, such as those developed for stmctured analysis and design and the object-oriented approach. [Pg.246]

Oxide semiconductors materials such as TiO, ZnO and SnO have a relatively wide band gap and cannot absorb sunlight in visible region and create electron. Nevertheless, in sensitization process, visible light could be absorbed by photosensitizer organic dye results creation of... [Pg.86]

This polymer-core/metal-shell type of the hybridized NCs has an inverse nanostructure of Sect. 3. Our research group has recently estabUshed the unique fabrication process, visible-light-driven photocatalytic reduction method [53], to PDA-core/metal-shell hybridized NCs. [Pg.161]
