A study has been made to investigate the radiation grafting of styrene onto poly(tetrafluoroethylene- co -perfluoropropylvinyl ether) (PFA) substrates, using the simultaneous irradiation method. Two PFA polymers of different comonomer perfluoropropyl vinyl ether (PPVE) content and degree of crystallinity were used. Ef…

We calculated the energy consumed for phase boundary motion in a ${\mathrm{Ni}}_{52}{\mathrm{Mn}}_{23}{\mathrm{Ga}}_{25}$ single-crystalline sample during martensitic transformation using a boundary friction phenomenological theory. It was found that the energy consumed for phase boundary motion is 13.14 J/mol, only a…

We investigate a system of one-dimensional Hubbard chains of interacting fermions coupled by interchain hopping. Using a generalization of the dynamical mean-field theory we study the deconfinement transition from a Mott insulator to a metal and the crossover between Luttinger and Fermi liquid phases. One-particle pro…

Supramolecular Chemistry deals with the design, synthesis and study of molecular structures held together by non-covalent interactions. Structures of this type are ubiquitous in nature and are frequently used as blueprints for the design of synthetic equivalents. This book is intended to demonstrate the seminal import…

Icicles with wave patterns on their surfaces can sometimes be seen hanging from roofs of buildings. Surprisingly, most of these wave patterns are at intervals of about 1 cm. The reason for this uniformity of interval has not been clarified. Here we show a formula to explain this remarkable phenomenon by introducing a…

This papers deals with overall phase transformation kinetics. The Fokker-Planck type equation is derived from the generalized nucleation theory proposed by Binder and Stauffer. Existence of the steady state solution is shown by a method based on the mean value theorem of differential calculus. From the analysis of asy…

Surfaces of surfactant-templated polyacrylamide hydrogels were imaged by atomic force microscopy (AFM), and the surface morphology was studied by numerical scaling analysis. The templated gels were formed by polymerizing acrylamide plus a cross-linker in the presence of surfactants, which were then removed by soaking…

The surface-enhanced Raman spectra (SERS) of adenine and three deuterated analogues adsorbed on colloids, electrochemically roughened electrodes, and vacuum deposited island films of silver have been investigated. All normal Raman and SERS bands were assigned to normal modes on the basis of density functional theory (…

The influence of quenched disorder on the competition between ordered states separated by a first-order transition is investigated. A phase diagram with features resembling quantum-critical behavior is observed, even using classical models. The low-temperature paramagnetic regime consists of coexisting ordered cluster…

Magnetization and magnetoresistance were measured in A-type antiferromagnet ${\mathrm{Nd}}_{0.45}{\mathrm{Sr}}_{0.55}{\mathrm{MnO}}_{3}$ utilizing pulsed magnetic fields up to 45 T. We have observed a ferromagnetic transition accompanied by a discontinuous decrease of resistivity. The temperature dependence of the res…

Abstract Nlon 6 fibers were zone drawn and zone annealed by using a continuous wave carbon dioxide laser to develop their mechanical properties. A laser‐heating zone drawing was carried out under a applied tension of 35.4 MPa at a power density of 9.65 W · cm −2 , and then the zone‐drawn fiber was annealed. A laser‐he…

Abstract The thermal stability of the heterogeneous nucleation effect of polypropylene (PP) nucleated with an organic phosphate (A) and two kinds of sorbitol derivatives (B and D) was investigated by DSC multiscanning. For pure PP, the peak temperature of crystallization ( T ) was little changed with an increasing num…

Nine crystal structures of free-base 5,15-diarylporphyrin derivatives are reported, and systematic analysis is made of the molecular conformations and intermolecular interactions in these and other comparable structures. In all cases, the porphyrins show minimal out-of-plane distortion in the solid state, but signific…

End product application is an important consideration when evaluating a material in an in vivo setting (Didisheim, Cardiovasc Pathol 1993;2:1S-2S). Small animal models allow high through-put evaluation of biocompatability. Previous preclinical evaluations have often used a rat subcutaneous model for the characterizati…

Abstract The P(O)‐H in 9,10‐dihydro‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) was used as an active group to react with the carbonyl group in 4,4′‐dihydroxybenzophenone (DHBP) to result a novel phosphorous‐containing biphenol compound (DOPO‐2OH). Phosphorous‐containing epoxy resins were therefore obtained from react…
