A sample holder, including optics for focusing the incident light and collecting the luminescence. Efficient light collection is important, and the sample holder may need to allow for a cryostat, pressure cell, magnet, or electrical contacts. 

Dr. Hui has worked on various projects, including chemical sensors, solid oxide fuel cells, magnetic materials, gas separation membranes, nanostruc-tured materials, thin film fabrication, and protective coatings for metals. He has more than 80 research publications, one worldwide patent, and one U.S. patent (pending). He is currently leading and involved in several projects for the development of metal-supported solid oxide fuel cells (SOFCs), ceramic nanomaterials as catalyst supports for high-temperature PEM fuel cells, protective ceramic coatings on metallic substrates, ceramic electrode materials for batteries, and ceramic proton conductors. Dr. Hui is also an active member of the Electrochemical Society and the American Ceramic Society.

An effective way of providing polarization control is the use of stirred cells. Magnetic stirring provides high ultrafiltration rates. 

The caustic flow to the electrolyzer feed header is measured and monitored to ensure that there is always a flow to the cells. Magnetic flow meters are standard. The low-flow switch depicted in Fig. 11.53 starts a delay timer when it trips. After the delay set on the timer, the rectifiers will shut down. If the caustic flow recovers in time, the timer resets automatically. 

Static Spectroscopic Cells. Magnetic resonance spectroscopy is widely used to monitor organometallic reactions and homogeneous catalytic reactions (72). Small diameter tubes ( 5 mm) are used in both ESR and NMR spectroscopies. Typically, the experimentalist adds solvent, reagent(s), complex, and ligand (in some order) inverts the tube a few times to effect mixing and then drops it into the ESR or NMR spectrometer to make measurements. In the case of the ESR, the tube is stationary, and in the case of NMR, the tube is rotating.

For liquid samples contained in a cell, it is necessary to measure the total magnetization of sample and cell and then correct for the separately measured magnetization of the cell. Considerable care is required because the cell magnetization can easily exceed that of the sample by a large factor. Cells for susceptibility measurements may be either metallic or insulating so a relatively wide choice of materials is avail-... 

The sample environment is generally an easily accessible region where a variety of equipment can be mounted in the beam, e.g. heating jackets, flow cells, magnets, stretching devices and automatic sample chargers. Each instrument has its own particular features, and details are obtainable from the parent institutions. Additional details are provided here of the LOQ diffractometer at ISIS. 

More recently, intense research efforts have been devoted to developing [60] fullerene-polymer hybrids in which [60]fuUerene molecules are incorporated onto polymer main chains or side chains [23-25]. These [60]fullerene-polymer hybrids have proven to be innovative materials, functioning as organic solar cells, magnets, photoconductors, optical-limiting devices and semiconductors [26-28]. Synthetically, the 30 highly reactive double bonds of a [60]fullerene molecule limit the possible polymerization reactions [24, 28-31]. However, supramolecular methods of incorporating [60]fullerene onto a polymer main chain can overcome this Umitation.
