Graphite pyrolitic

An algorithm has been developed to predict the thermal conductivity degradation for a high thermal conductivity composite ( 555 W/m-K at room temperature) as a function of radiation dose and temperature [33]. The absence of irradiation data on CFCs of this type required the use of data from intermediate thermal conductivity materials as well as pyrolitic graphite to derive an empirical radiation damage term [14, 17, 19, 25, 26]. 

Chemical erosion can be suppressed by doping with substitutional elements such as boron. This is demonstrated in Fig. 14 [47] which shows data for undoped pyrolitic graphite and several grades of boron doped graphite. The mechanism responsible for this suppression may include the reduced chemical activity of the boronized material, as demonstrated by the increased oxidation resistance of B doped carbons [48] or the suppressed diffusion caused by the interstitial trapping at boron sites.

As an ex situ technique for structural information on surfaces, STM is an excellent complement to the standard electron and ion diffraction probes of surface order. The STM method can identify both short range order and long range periodicity, as well as disordered surface layers (e.g., images of sorbic acid on Highly Ordered Pyrolitic Graphite (HOPG), vida infra). In contrast,...

Since rusticyanin is positively charged (p/=9.1), its electrochemical response should be tested at negatively charged electrodes (namely, edge-plane pyrolitic graphite or glassy carbon electrodes). As a matter of fact, no positive response is obtained at a carbon paste electrode, but in the presence of a promoter such as 4,4/-bipyridyl a sufficiently resolved cyclic voltammetric response is obtained, Figure 37.67...
