Reflector advantages

Table 1 (4,5) lists some useful properties of several graphites used for moderators or reflectors in nuclear reactors. Reactor designers have taken advantage of graphite s properties in applying the material to other than moderator and reflector components, usually in conjunction with some other material. 

A Michelson interferometer (MI) can be considered as a Young-interferometer with perfect reflectors at the ends of both branches. Compared to the MZI and YI the MI has the advantage that the sensing region is passed twice. Because for monitoring the reflected light a second Y- junction is... 

Example Regardless of the manufacturer of the hardware, the effect of a time lag on resolution is quite dramatic. The resolving power of linear instruments is improved by a factor of 3-4 and reflector instruments become better by a factor of about 2-3. [36] The advantages are obvious by comparison of the molecular ion signal of Ceo as obtained from a ReTOF instrument with continuous extraction (Fig. 4.7) and from the same instrument after upgrading with PIE (Fig. 4.12), or by examination of MALDI-TOF spectra of substance P, a low mass peptide, as obtained in continuous extraction mode and after PIE upgrade of the same instrument (Eig. 4.11). 

A balloon-borne, open path, tunable diode laser spectrometer (21) provides a particularly elegant technique that combines the advantages of in situ and remote sampling. The radiation absorption path is defined by the laser on the balloon gondola and a retro reflector suspended up to 500 m below. Thus, a well-defined parcel of air is analyzed and the effects of sampling inlets are avoided. NO, NO , HN03, N20, and 03 have been measured simultaneously (22). 

ZnO can be advantageously used as TCO layer in various kinds of thin film silicon solar cells, either as back or as front contact, or even as an intermediate reflector between the amorphous and the microcrystalline p-i-n junctions, within the micromorph tandem solar cell [58] (see also Chap. 8). Figure 6.48 illustrates the various possibilities for using a ZnO layer within a thin film silicon solar cell. In the present paragraph, we will comment about the use of CVD ZnO both as front contact (or window layer) and also as back contact (or part of the back reflector). 

In practice more sophisticated double focussing arrangements are usually used, several of which are shown in figure 10.23. The Cassegrain, Gregory and Nasmyth systems are in common use, and the offset Cassegrain system has the advantage that the secondary reflector does not block the field of view of the primary dish... 

Neo-amylose is suited for food and non-food applications. Due to its resistant starch properties it is suited for use as dietary fiber [139]. Beside this food application, smooth spherical microparticles with a size of 10-100 pm are accessible by recrystaUization of Neo-amylose in dimethylsulfoxide (DMSO). These are suited as cosmetics additive in creams, lotions, or as UV-reflectors [140]. Furthermore, Neo-amylose has proved to be an advantageous constituent in hard or soft films in order to generate gelatin free capsules [139].
