Impression creep tests of LiF single crystals at 600–750[ddot]C and under punching stresses of 4-30 MN/m2 are reported. Both temperature and stress dependences are comparable with those of conventional compression creep tests under similar conditions. These dependences give a power law stress exponent of 4–5 and an ac…

An x-ray diffraction study of Nylon 11 was carried out at high pressures and high temperatures. Careful measurements made on both wet and dry samples at atmospheric pressure indicated that the structure of Nylon 11 suggested by Slichter was not quite correct. Some distortion of the planar conformation causes a shorten…

The theory of exchange narrowing is extended in systems with large isotropic ${J}_{0}$ to include static spin correlations and antisymmetric exchange. Both contribute to the unusual temperature-dependent, exchange-narrowed EPR linewidth $\ensuremath{\Delta}H(T)$ in $\mathrm{Cu}X_{4}^{}{}_{}{}^{2\ensuremath{-}} (X=\mat…

Relaxation of excited electronic states of rare-earth ions by multiphonon emission was investigated in a beryllium-fluoride glass. Decay rates were measured from the transient fluorescence following pulsed laser excitation of selected states. The multiphonon emission rates exhibit an approximately exponential dependen…

Late during sporulation, Bacillus subtilis produces glucose dehydrogenase (GlcDH; EC 1.1.1.47), which can react with D-glucose or 2-deoxy-D-glucose and can use nicotinamide adenine dinucleotide (NAD) or nicotinamide adenine dinucleotide phosphate (NADP) as a cofactor. This enzyme is found mainly in the forespore compa…

Structure-property relationships were investigated for blends of grafted rubbery polymers with PVC. Increasing grafting levels as well as higher blending temperatures improved the dispersion of the graft copolymers in PVC, lowered the impact strength, and reduced stress whitening. Presuming a mechanistic connection be…

A high-angle tilt grain boundary viewed end-on in a (011) thin crystal of Ge has been imaged with atomic resolution in the Kyoto 500 kV electron microscope. The boundary is shown to consist of alternating columns of five- and seven-membered rings of Ge atoms running along the [011] direction, and to contain no danglin…

The room-temperature damping of three Fe-18Cr-Ni alloys was determined as a function of vibrational strain amplitude at 80 kHz. The data are consistent with the Granato-Lücke theory of dislocation damping. Values of Lc (distance between minor pins) measured are consistent with those obtained from a thermodynamic analy…

The rate-independent theory of transverse impact of textile fibers is reviewed and cast in a form that provides convenient preliminary guidance to designers of impact-resistant textile structures. It is shown that energy-absorption rate increases monotonically with fiber modulus, but that decreased ductility at high m…

Morphological observations revealed that internal crazes are nucleated by a hydrostatic stress component caused by plastic constraint ahead of the fully developed plastic deformation zone. The…
