Chain reorientation in ß-PVDF films upon transverse mechanical deformation studied by SEM and dielectric relaxation [PDF]

, 2003
Chain reorientation may be induced in polyvinylidene fluoride (PVDF) in its ß-phase by applying a deformation perpendicular to the pre-oriented polymeric chains.

Influence of Botanical Origin on the Optical, Surface, and Nanomechanical Properties of Nanocellulose‐Based Films: A Comparative Study

Journal of Applied Polymer Science, EarlyView.
Schematic representation of the processing and multiscale characterization of nanocellulose films from different botanical sources. ABSTRACT Although the influence of botanical origin on nanocellulose properties is well recognized, an integrated multiscale framework linking chemical composition, fractal surface descriptors, and nanomechanical behavior ...

Inverse semigroups generated by linear transformations [PDF]

, 2005
Suppose X is a set with cardinal p and let q be an infinite cardinal less or equal than p. Let B=BL(p,q) denote the Baer-Levi semigroup defined on X. In 1984, Howie and Marques-Smith showed that, if p=q, then BB^{-1}=I(X), the symmetric inverse semigroup

Understanding Oxide Surface Stability: Theoretical Insights From Silver Chromate

Advanced Physics Research, EarlyView.
Seven low‐index Miller surfaces, comprising 46 distinct terminations, were systematically investigated to determine their surface free energies as functions of the chemical potentials of the system constituents. The competition among these terminations gives rise to temperature‐dependent stability crossovers that dynamically reshape the surface energy ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
