Fluid immersion

Table 3 also lists the density p of these alloys, which was measured by the Achemedes principle using pure ethanol as immersion fluid. To monitor the accuracy of the measurements, the density of 99.999% pure Al shots was also measured and it was found to be within 0.4% from its accepted value. [Pg.295]

For further enhancement of the resolution at 193 nm, immersion lithography employing water as an optical element between the last lens and resist has emerged recently as a new technology in competition with 157 nm lithography. In immersion lithography the effective exposure wavelength is reduced by the refractive index of the immersion fluid (193/1.44= 134 nm for 193 nm water immersion). [Pg.121]

The identification of the particles is not immediately clear, however. It has been the fashion to speak of these as rodlet micelles, but further discussion below indicates that the only elements which might be involved here are the fibril and the protofibril. The latter are closely packed into fibrils and offer limited and peculiar possibilities for an interpenetration of the immersion fluids used to demonstrate the form double refraction. Perhaps the fibrils supply the major form effects. [Pg.98]

The chamber slide is then placed into the temperature control cube chamber equipped on Leica SP5 microscope systems see Note 1 and 5 and Fig. Id). Glycerol (70% in H O) is used as an immersion fluid. [Pg.204]

ASTM D2732 [136] is applied to films and sheeting not more than 0.76 mm thick. The test pieces consist of squares 100 mm on a side that are placed in holders that keep the te.st piece flat but allow intimate access of the immersion fluid to the full surface area of the sample. The test pieces are immersed in a suitable fluid at the agreed temperature for the material (determined by the interested parties or the material specification) for a period of 10 seconds and then removed and quickly plunged into a fluid bath at ambient temperature for a further 5 seconds for cooling. The final dimensional measurements must be made within 30 minutes of removal from the cooling bath. [Pg.343]

The wetting behavior of a large variety of surfaces is of crucial importance for their key applications. These applications extend from consumer products such as architectural glass, automotive mirrors and eye glasses where cleaning aspects play a dominant role, to engineering components like steel surfaces with critical lubrication properties, fluid repellence of medical instruments, to ultra-precision optics designed for operation in immersion fluids. Ultra-hydrophobicity has proved as a... [Pg.19]

Recently, manufacturers have designed objectives with even higher numerical apertures that would be ideal for TIR experiments with high refractive index samples (see Section 3.6). However, these objectives require special immersion fluid and coverslip materials, which may have implications for other aspects of the experiments such as surface immobilization chemistry and cost. In essence the TIR configuration is identical to the epi-fluorescence configuration discussed earlier, with the exception of the excitation beam convergence and positioning with respect to the optical axis of the objective. [Pg.116]

Uniaxial tensile strength can be measured in an Instron test machines equipped with a static load cell of suitable capacity (see Fig. 10.1). To measure the tensile properties of the membranes while immersed in a fluid, an assembly consisting of a testing chamber and tensile grips are fitted for the Instron machine. DMTA technique has the option of performing mechanical testing in immersed fluids. [Pg.236]

Electrode problems in the measurement of very thin plastic Aims can be overcome with the fluid-displacement methods described in ASTM D 1531. This method is speciflc for polyethylene, but can be used for other films. The immersion fluid should not attack the film and its dielectric constant should approximate that of the test specimen. Anhydrous benzene, silicone, and fluorocarbon liquids are often used the liquids must be completely free from moisture. [Pg.359]

The swelling of polychloroprene vulcanisates by oils, chemicals and solvents may be reduced considerably by increasing the state of cure, by increasing the amount of loading, or by using a plasticiser which is miscible with the immersion fluid and consequently is extracted by it. Highly... [Pg.144]
