    Notes: A miniature diamond anvil cell (DAC) of overall dimensions φ10×24 mm made of nonmagnetic NiCrAl alloy is described. A new design permits the alignment of anvil flats as perfectly as in traditional DACs. A lever-arm assembly and a fiber-optical system for the cell are described. Two example of experimental results obtained with the cell are given, namely the pressure dependence of the refractive index of diamond and the pressure-induced shifts in the photoluminescence peaks of a quantum well sample. A maximum pressure of 110 GPa was reached with beveled anvils.

    Nanotubes in boron nitride laser heated at high pressure (1996)

    Notes: Here we report on the finding of pure boron nitride (BN) nanotubes that do not contain any additional inclusions and on a new method for their growth: laser heating of boron nitrides at high nitrogen pressure (5–15 GPa). The multiwalled nanotubes were observed using high resolution electron microscopy and were chemically characterized by electron energy loss spectroscopy. The circular or polygonal cross-sectional nanotubes, which have 3–8 shells and a characteristic outer dimension cross section of 3–15 nm, were found to have grown either in melted cubic BN or in hexagonal+amorphous BN that had recrystallized on the specimen's surface from the fluid phase. © 1996 American Institute of Physics.

    Notes: [Auszug] Among the simple diatomic molecules, oxygen is of particular interest because it shows magnetism at low temperatures. Moreover, at pressures exceeding 95 GPa (∼0.95 Mbar), solid molecular oxygen becomes metallic, accompanied by a structural transition. The metallization ...
