    Notes: [Auszug] IN spite of the considerable literature, there seems to be no special reference1 to the properties of diethyl peroxide as a pro-knock. In view of its possible importance in some theories of hydrocarbon combustion, it was of interest to investigate its behaviour in the engine. ...

    Notes: [Auszug] To improve the crystal perfection of pyrolytic graphite deposited at 2,100-2,500 C, conventional annealing techniques have been applied. However, temperatures of about 3,500 C are required to achieve satisfactory ordering of the basal planes3. In common with other laboratories we have found two ...

    Notes: [Auszug] Recently, we have been able to carry out experiments on pieces of graphite in which the preferred orientation of the carbon hexagon networks is so good that the results permit definite inferences about the behaviour of single crystals, and in particular about the anisotropy of the electronic ...

    Notes: [Auszug] If such defect sites are completely closed in by macro-aromatic network, 'aromatic holes' are formed. Two examples are illustrated in Fig. 1, but there are many others. If they are situated at re-entrant portions of the network which are not closed, 'claw defects' are formed. One type is ...

    Notes: [Auszug] Gas kinetic studies have shown4 that even normal paraffins are extensively crumpled at ordinary temperatures, as a result of rotations about C-C single bonds. Molecular flexibility seems to be an important factor in facilitating transfer of internal energy in gaseous collisions. In mass diffusion, ...

    Notes: [Auszug] PROF. W. T. DAVID in the first paragraph of his letter under this title1 makes two points about the afterglow in the gases from names or explosive reactions; the first that the temperatures determined by the sodium flame reversal method are too high, compared presumably with the ...

    Notes: [Auszug] WITHIN recent years the concept1 that graphite presents a transition between aromatic and metallic electrons has been elaborated in a number of theoretical and experimental studies. Various considerations suggest that graphite is much more markedly metallic in one principal direction in the ...

    Notes: [Auszug] It is now suggested that, in reality, instead of making true geometrical intersection or contact at the transition point, the free-energy surfaces may exhibit an 'indeterminacy thickening' in the transition region. On this basis, it is not necessary to assume that the surfaces Gx and G2 make true ...
