Abstract Today, material science is directed towards the development of multifunctional and oriented structures. One example of such supramolecular systems are liquid crystalline (LC) elastomers which combine the properties of LC phase (the combination of order and mobility) with rubber elasticity, one of the most typ…
Abstract A review is presented of work carried out over the last 40 years on non-porous sorbents and on microporous shape-selective sorbents derived from palygorskite, smectite, and vermiculite. Among such materials four kinds of behavior were observed. In some systems uptake was restricted to external surfaces; in ot…

Machine learning (ML) is transforming all areas of science. The complex and time-consuming calculations in molecular simulations are particularly suitable for an ML revolution and have already been profoundly affected by the application of existing ML ...Read More
Transmission Laue diffraction photographs can be recorded with short exposure times from stationary macromolecular and small-molecule crystals. With the use of a broad wavelength band a very large number of reflections is stimulated in a single `snapshot' of large regions of reciprocal space. Processing software has b…

In order to study the effects of factors governing the bioabsorption rate of polylactides, implantation tests were carried out in rabbits using various samples (20 x 10 x 2 mm3) differing in their chemical composition, residual monomer content, and molecular orientation. Copolymer samples with a higher lactic acid con…
The orientation distribution function (ODF) of the crystallites of polycrystalline materials can be calculated from experimentally measured pole density distribution functions (pole figures). This procedure, called pole-figure inversion, can be achieved by the series-expansion method (harmonic method). As a consequenc…

A1 (purity, 99·7%) with 0·1 or 2 mm grains was torsionally deformed at 400°C and 0·2s-1 up to equivalent strains of 60. Tangential sections were examined by polarized light, transmission electron microscopy and scanning electron microscopy. The grains wound into helicoids with an axial thickness varying inversely with…
An interactive program, POWD, written in Fortran77, for powder diffraction data interpretation and indexing is described. Various functions such as the least-squares refinement and the systematic absence test are also included in this versatile program. The modified de Wolff figure of merit [Wu (1988). J. Appl. Cryst.…
Peptidylarginine deiminase (proteinarginine iminohydrolase, EC 3.5.3.15) converted some arginine residues to citrulline residues in soluble vimentin, in a micromolar Ca2+-dependent manner and resulted in the loss of polymerization competence of the intermediate filament protein. When about 8 mol of residues/mol of vim…
The lattice model for linear polymeric glasses proposed by Gibbs and Di Marzio several decades ago is used to calculate the average relaxation time for the structure of the model as a function of temperature. Using the fact that the model exhibits the existence of a temperature ${T}_{0}$ for which the configurational…
The pressure drop and wetting film thickness for isolated bubbles and bubble trains moving in circular and square capillaries are computed. An arclength-angle formulation of a composite lubrication equation allows for the numerical matching of the lubrication solution of the transition region to the static profiles aw…
