The structure, mechanism of formation and thermal reaction of electronic defects associated with Ge in GeO 2 -doped silica fiber induced by fiber-drawing or γ-irradiation were studied by detecting ESR hyperfine structures due to 73 Ge. The present assignment of the drawing-induced center to the Ge-E' center was confir…

The defect center causing the 2 eV absorption band induced in pure silica core fibers by 60 Co γ-rays is discussed. The 2 eV band and non-bridging oxygen hole center (NBOHC, SI–O·) show almost the same thermal annealing characteristics. The peak wavelength of the 2 eV band in low-OH (≦6 ppm) fibers is 630 nm, but shif…

Abstract A study was made of the extent to which the lateral surfaces contribute to the surface area of five kaolinites of different crystallinities. Methods used included the low-temperature adsorption of N 2 and Ar as measured by a volumetric technique coupled with microcalorimetry, the interpretation of the adsorpt…

A magnetic field suppresses turbulence and thermal convection in a Czochralski crystal puller. The amounts and distributions of dopants and oxygen in the crystal are determined by the motion of the molten silicon during crystal growth. This paper presents analytical solutions for the melt motion in a Czochralski pulle…

Mutual orientation effects on the rate of nonadiabatic electron transfer between several diporphyrin pairs of experimental \ninterest are examined. The electronic matrix element for electron transfer is calculated within a one-electron spheroidal \nmodel for a variety of states and orientations which are relev…

Unlike the orthorhombic phase, the icosahedral phase of ${\mathrm{Al}}_{86}$${\mathrm{Mn}}_{14}$ exhibits a local magnetic moment. The effective moment of icosahedral-phase Al-Mn and Al-Si-Mn alloys increases with Mn concentration up to a maximum of (1.5\ifmmode\pm\else\textpm\fi{}0.5${\ensuremath{\mu}}_{B}$). The amo…

The Sludge-to-Oil Reactor System (STORS) continuously converted over 400 gallons (20% solids) of sewage sludge to oil during 100 hours of operation. About 80% of the energy in the sludge was recovered as an oil and char. The energy recovered was sufficient to make the STORS energy self-sufficient assuming the char is…

Using X-ray diffraction methods it has been ascertained that the intermediate phase in Sn2P2Se6 crystals existing in the range 193 K to 220 K and preceding the ferroelectric transition at 193 K is an incommensurate phase. Modulated structure is characterized by the wave vector q(T) = (-1.146 δ(T)a*, 0, δ(T)c*), where…
