Abstract Lithiumdihydrogenphosphat, LiH 2 PO 4 , wird beim Erhitzen zu Lithiumpolyphosphat, (LiPO 3 ) n · H 2 O, dehydratisiert [2–5]. Mit Lithiumcyclohexaphosphat, Li 6 P 6 O 18 , angeimpftes LiH 2 PO 4 wird dagegen strukturkontrolliert zu reinem Li 6 P 6 O 18 dehydratisiert. Lithiumhydrogendiphosphat, Li 3 HP 2 O 7…
Explicit expressions are obtained for the stress and displacement fields near the tip of a rigid line inhomogeneity subjected to an inclined loading. It is shown that the tip stress field, with a square-root singularity, differs in characteristics from that of a slit crack. New designations for the mode of deformation…
Abstract The vibrational modes of clay minerals in aqueous suspension are uniquely accessible to Raman spectroscopy, but this potentially powerful approach has not been applied heretofore to study clays in aqueous samples. In this paper, Raman spectra in the 100- to 4000-cm −1 region were obtained for kaolinite in aqu…
Abstract The structure of nylon 6 fibers is analyzed by x‐ray diffraction. Our results suggest that only two forms of nylon 6, α and γ, along with lattice distortion and crystallite size, are sufficient to explain the whole range of crystalline structures observed in nylon 6. The γ phase is the preferred initial form…

A model for laser melting of carbon at high temperatures to form liquid carbon has been developed. This model is solved numerically using experimental data from laser irradiation studies in graphite consistent with a melting temperature for graphite of 4300 K. The parameters for high-temperature graphite are based on…

Intrinsic thermal clothing insulation and surface air insulation were measured on human subjects by the use of indirect calorimetry. Four male clothing ensembles (0-1-1 -8 clo) and three female clothing ensembles (0-2-1-2 clo) were investigated. Using the standing position as a reference, the influence of sitting, bic…

Abstract The crystal structure of the kaolinite: dimethylsulfoxide (DMSO) intercalate ( P 1, a = 5.187(2), b = 8.964(3), c = 11.838(4) Å, α = 91.53(1)°, β = 108.59(2), γ = 89.92(1)°) has been determined using spectroscopic and X-ray and neutron powder diffraction data. Both the X-ray and neutron powder diffraction pat…

The textural attributes of 8 different heat‐induced protein gel preparations evaluated by torsion failure testing and Instron texture profile analysis (TPA) were compared to sensory ratings by a trained texture profile panel. The gels presented a wide range of textural properties as determined by the instrumental and…
Abstract The thickness, length, width, area and perimeter of 575 particles from 16 aqueously dispersed samples of a variety of interstratified clays, smectites and illite have been recorded using TEM techniques. Complete dispersion of the clay material was achieved by saturating the clay with either Na + or Li + , rem…

A metastable phase with the point group symmetry m35 but no ordinary translation symmetry has been found in rapidly quenched (Ti 1−xVx)2Ni alloys with × = 00-0-3 by electron diffraction and high-resolution electron microscopy.
The class of ‘‘facilitated’’ kinetic Ising models introduced in a recent letter is investigated in greater detail. An interpretation of the models in terms of relaxation processes in dense fluids is described. Various types of kinetic behavior are predicted for the different spin models: (A) Arrhenius temperature depe…
Leader peptidase cleaves the amino-terminal leader sequences of many secreted and membrane proteins. We have examined the function of leader peptidase by constructing an Escherichia coli strain where its synthesis is controlled by the arabinose B promoter. This strain requires arabinose for growth. When the synthesis…
