A Bioinspired Design of Protective AlO/Polyurethane Hierarchical Composite Film Through Layer-By-Layer Deposition.

Structural materials such as ceramics, metals, and carbon fiber-reinforced plastics (CFRP) are frequently threatened by large compressive and impact forces. Energy absorption layers, i.e.

Two new 3-hexenol glycosides from the calyces of var. .

Two new hexenol glycosides, ()-hex-3-en-1-ol O--d-xylcopyranosyl-(1-6)- -d-glucopyranosyl-(1-2)--d-glucopyranoside () and ()-hex-3-en-1-ol O--d-xylcopyranosyl-(1-6)--d-glucopyranosyl-(1-2)--d-glucopyranoside (2), were isolated from the 50% ethanol elution of macroporous resin of var. . Their structures were established by detailed spectroscopic analysis, including extensive 2D-NMR data.

A class of scale-free networks with fractal structure based on subshift of finite type.

In this paper, given a time series generated by a certain dynamical system, we construct a new class of scale-free networks with fractal structure based on the subshift of finite type and base graphs. To simplify our model, we suppose the base graphs are bipartite graphs and the subshift has the special form. When embedding our growing network into the plane, we find its image is a graph-directed self-affine fractal, whose Hausdorff dimension is related to the power law exponent of cumulative degree distribution.
