Abstract The synthesis of hexabenz‐1,12;2,3;4,5;6,7;8,9;10,11‐coronene, using two different reaction schemes is described. The cyclodehydrogenation of hexaphenylbenzene, and the reaction of dibenz‐1,9;2,3‐anthrone with Zn/ZnCl 2 lead to identical products, the chemical and crystallographic properties of which demonstr…

The intrinsic optical absorption spectrum of PbS crystals has been measured. The absorption coefficients range from about 10 ${\mathrm{cm}}^{\ensuremath{-}1}$ to ${10}^{5}$ ${\mathrm{cm}}^{\ensuremath{-}1}$ giving continuous data through the band edge. At 300\ifmmode^\circ\else\textdegree\fi{}K the data indicate a dir…

Scale formed upon molybdenum consists of either two or three oxide layers., depending upon temperature and time. The outermost layer is the volatile MoO3. The inner layers of oxide have a composition very close to MoO2 but do not exhibit an X-ray pattern corresponding to MoO2. The rate of evaporation of MoO3 and the m…

The effect of current density, p H, and temperature on the anodic behavior, cathodic behavior, and corrosion of magnesium in aqueous solutions has been studied. A tentative mechanism for the anodic oxidation of magnesium is postulated. Local corrosion and/or undermining of metallic magnesium at the anode are appreciab…

The re-examination of the crystal structure of α-hexagonal BaAl2Si2O8 has revealed that the true symmetry of the crystal is lower than hexagonal-possibly, orthorhombic with a body centered lattice of dimensions: a=5.293, b=9.168 and c=7.79×2Å, and the crystals invariably occur in a trilling form made up by three ortho…

The surface tension of a commercial soda‐lime‐silica glass was measured in various atmospheres in the temperature range 500° to 700° C. The method of fiber elongation was used and its usefulness is illustrated. Water vapor was found to exhibit the most pronounced effect, causing a lowering from 315 to 205 dynes cm. −1…

Phase relationships in the system Li 2 O, B 2 O 3 ‐B 2 O 3 were studied by the quenching method using twenty compositions. The crystalline phases encountered were ( a ) Li 2 O, B 2 O 3 , which melts congruently at 849°± 2°C., ( b ) Li 2 O.‐2B 2 O 3 , which melts congruently at 917°± 2°C., ( c ) a new compound, 2Li 2 O…

All passivating‐type inhibitors are oxidizing agents. However, not all oxidizing agents are inhibitors. A passivating ‐type inhibitor functions by producing local‐action current which anodically polarizes a metal into the passive potential region and thereby provides the means for obtaining a noble mixed potential. Th…

In einem Cosseratschen Kontinuum ist jedem Punkt einer stetigen Punktmenge eine räumliche Orientierung zugeordnet. Es werden die kinematischen und statischen Gleichungen eines solchen Kontinuums aufgestellt und die Analogien zwischen diesen Gleichungssystemen besprochen.

Low- and high-temperature x-ray diffraction investigations of titanium dihydride (TiH/sub 1.99/) and dideuteride (TiD/sub 1.98/) have indicated apparent 'second-order transformations' in both substances below a critical temperature of 310 deg K. The tetragonal low-temperature phases are distortions of the cubic fluori…
