Usually bimetallic nanoparticles as well as monometallic ones are characterized by many probing tools such as UV-visible (UV-Vis) spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), EXAFS, infrared spectroscopy of adsorbed CO (CO-IR), and so on [1,2]. 

Measurement of Deposit. Common methods used to measure sediments are manual testing, sedimentation balance, radioactive methods, dipping of bodies, and probe tools. 

The oldest microscopy technique for materials analysis was optical microscopy. Even to this day, for feature sizes above 1 pm, this is one of the most popular tools. For smaller features, electron microscopy techniques such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are the tools of choice. A third family of microscopy includes scanning probe tools such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM). In these relatively recent techniques, sample preparation concerns are of minor importance compared to other problems, such as vibration isolation and processing of atomically sharp probes. Therefore, the latter techniques are not discussed here. This chapter is aimed at introducing the user to general specimen preparation steps involved in optical and electron microscopy [3 7], which to date are the most common... 

Ga NMR studies have received increased impetus as a viable probing tool for some key areas. Ga NMR studies have been used to support and follow Ga antitumor agents and their mode of action and uptake into tumor cells. Ga NMR has thus been used to study how various ligands may form complexes with the cation. In another area, the use of - Ga NMR has been used to examine defects in semiconductors, which can have a crucial influence on the semiconductors electronic and optical properties. In addition, a number of very useful web sites detailing Ga NMR related studies are available. " ... 

This demonstrates the power of the mixed catalyst technique as a probing tool which can go far beyond the capabilities of analytical methods in the detection of participating product species (see Section III).

Three-dimensional flow analysis is much more demanding computationally but is necessary to capture the full detailed characteristics of FSW. Added detail in 3-D includes complete tools with shoulder and probe tool tilt probe features such as threads, helical flutes, and taper in diameter and flow below the pin— important for avoiding root defects. The output of 3-D CFD is essentially the same as in 2-D, but flow paths are more difficult to present graphically, requiring 2-D slices or isometric views. Figure... 

Infrared (IR) spectroscopy plays a very important role in the physical characterization of polymers. IR absorption bands are well known for their marked specificity to individual chemical functionalities. Furthermore, the unique sensitivity toward the configuration, conformation, and other local sub- and supramolecular environments (e.g., different phases of semicrystalline polymers, moieties participating in specific interactions of miscible blends, and block polymer segments undergoing different stages of relaxation processes) makes IR spectroscopy a very powerful probing tool for numerous scientific investigations in polymer physics. 

Neutron scattering is used to study the structure of polymers including polymer chain dimensions, conformations, miscibility of blends structures of block copolymers, semicrystalline polymers and biomacromolecules. The unique property of neutrality makes a neutron an excellent probing tool for... 

Permanent attachments such as footrings, headrings, neckrings or marking plates should be inspected to make sure they are in place and firmly attached. The area of attachment to the cylinder should be checked for possible entry of moisture to the cylinder surfaces that cannot be seen. In the case of adhesive attachments, any evidence of a break in the seal is cause for removal of the attachment. The use of a dull probing tool is recommended. Attachments made of plastic also must be checked carefully for gouges or splits, which would require their removal. When the cylinder bears a removable attachment such as a removable boot (footring), the attachment must be removed for visual inspection. 

AC impedance spectroscopy is a useful probing tool for investigating membrane cation contamination. If the current through the membrane is varied slightly by a sinusoidal perturbation, the ionic potential everywhere will... 

Electrical testers can take on many forms, but are generally divided into two major categories, the bed-of-nails and the flying probe. Tooling for a bed-of-nails tester consists of outputting data to manufacture a fixture to accommodate the pins, which make contact with the circuit nets. When a flying probe tester is employed, the net data are fed into the machine, which uses its own software to configure the routine to probe continuity and perform isolation. 

In this frame, Fe Mossbauer spectrometry which is a local atomic probe tool highly sensitive to the atomic neighbouring, appears as an excellent technique to investigate nanomaterials [10-13] one expects to distinguish atoms belonging to the crystalline zones from those located either at the surfaces of nanoparticles... 

Further investigations are needed to better understand the mechanism(s) of Li storage in nanostructured metals, including theoretical quantum chemistry first principles, methods, and local probes tools such as electron transmission microscopy, X-ray photoelectron spectroscopy, and electron energy loss spectrometry.
