The hydrogen treatment procedures, tensile, compression and torsion tests at fixed temperatures, transmission electron or optical microscopy at room temperature as well as X-ray diffraction measurements were detailed elsewhere All experiments were performed so as to compare properties of the same alloy, but modified using different treatment procedures. 

Fig. 3.16 Schematic drawing of the MIMOS II Mossbauer spectrometer. The position of the loudspeaker type velocity transducer to which both the reference and main Co/Rh sources are attached is shown. The room temperature transmission spectrum for a prototype internal reference standard shows the peaks corresponding to hematite (a-Fe203), a-Fe, and magnetite (Fe304). The internal reference standards for MIMOS II flight units are hematite, magnetite, and metallic iron. The backscatter spectrum for magnetite (from the external CCT (Compositional Calibration Target) on the rover) is also shown...

Bronze is the most popular metallic filler, although steel powder is occasionally used. Laige quantities (40%-60% by weight) of bronze reduce deformation under load and raise thermal and electrical conductivity of PTFE compounds. These two characteristics are beneficial to applications where a part is subjected to load at extreme temperatures. Transmission and air-conditioner compressor seals are two examples of such parts. Bronze is an alloy of copper... 

A technique called cryogenic temperature transmission electron microscopy (cryo-TEM) has been used by biologists for some years but is now also being used by chemists to examine a wide range of samples. CryoTEM involves the fast cooling of a thin film of liquid sample and transferring the sample into the TEM where it is maintained at...

Our recent low-temperature transmission electron microscopy study [39] has shown that these peaks are due to twinning within martensite. This process releases energy during heating or cooling, thereby yielding exothermic peaks.

The possible experimental setup to perform in situ high-temperature transmission Mossbauer spectra is shown in Fig. 18.31. A powdered sample is uniformly spread on quartz wool and put into a quartz tube. The tube is then inserted into the special furnace (see Fig. 18.31). The furnace was placed between source and detector of the Mossbauer spectrometer. The temperature inside the furnace was regulated accurately by PID (Proportional-Integral-Derivative)... 

The experimental-theoretical study of mesophase formation in amphiphilic systems emphasizes the basic chemical, physical, and materials science aspects of the systems. The most commonly discussed mesophases, beyond the simple micelles discussed in Chapter 4, are lamellar aggregated micellar (packed in various cubic and hexagonal close-packed arrays), columnar or ribbon phases (rod-shaped micelles stacked in a two-dimensional hexagonal or rectangular array) microemulsions, and the cubic bicontinuous mesophases. The experimental techniques normally used to identify these mesophases are NMR Uneshape analysis, diffusion measurements, smaU-angle neutron and X-ray scattering, and optical texture analyses. In addition, reconstraction of electron density profiles and very low temperature transmission electron microscopy (TEM) have been used to elucidate the details of these mesostractures.
