Mesoscopic Dynamics and Rheology of Inhomogeneous Polymers Based on Variable Cell Shape Dynamic Self-Consistent Field Theory
We introduce the variable cell shape method into dynamic self-consistent field theory (DSCFT), which may be used as a tool to investigate the dynamic and mechanical properties of complex inhomogeneous polymer system.

Effects of hard-segment content on the shape memory properties of segmented polyurethanes
关键字：hard-segment content, segmented polyurethanes
Some segmented polyurethanes are reported showing shape memory properties. Whereas the relationship between structures and shape-memory properties of these polymers is still not clear. In this study, a series of polyurethanes having crystal...

Shape of Fluid Vesicles Anchored by Rigid Rod
关键字：Shape,Fluid,Vesicles,Anchored,Rigid,Rod,
As a simple model of biological membranes, in recent years, tremendous interest has been focused on the polymer anchored vesicles. For many real cell membranes, the ‘ornaments‘ which anchored on membrane usually are semiflexible ...

Shape Characterization and Recognition of Cross-Section of Profiled Fibre by Microscopy and Image Analysis
关键字：Image Analysis
In order to describe the cross-section shape of profiled polyacrylonitrile fiber(PAN) in different aspects, four shape factors, i.e. Flatness (FL), Roundness (R), Concavity (CO) and Asymmetry (AS) were proposed and calculated using cross-se...

An Automatic Microscope Image System on Textile Fibers
关键字：Automatic microscope, quantitative measure, shape index, resin slice
With the development of chemical fiber forming technology, it is necessary that quantificational methods replace qualitative methods for cross shape measure. So an automatic image analysis system on textile fibers is developed to repla...

SHAPE-MEMORY PERFORMANCE OF SEGMENTAL POLYCAPROLACTONE POLYURETHANE
关键字：SHAPE,MEMORY,PERFORMANCE,SEGMENTAL,POLYCAPROLACTONE,POLYURETHANE,
Since the shape memory effect was reported in 1996 for segmental polyurethanes [1], especially since R. Langer et al. described their potential application in medical fields [2], shape-memory polymers,as new intelligent materials, have ...

Multiple-responsive shape memory polyacrylonitrile/graphene nanocomposites with rapid self-healing and recycling properties
It still remains a great challenge to endow polymer materials with multiple superior material properties by precise molecular design. Herein, we report a Diels–Alder (DA) based crosslinked polyacrylonitrile/graphene nanocomposite (PAN-DA/GR), which has multiple-responsive properties of shape memory,self-healing, and reprocessing in addition to enhanced mechanical properties. The graphene sheets, ...

Hydrothermally prepared nanosized and mesoporous Ce0.4Zr0.6O2 solid solutions with shape dependence in photocatalysis for the degradation of methylene blue
Mesoporous Ce0.4Zr0.6O2 solid solutions with four different shapes, including mixed nanorod and nanoparticle (RP, cubic), nanopolyhedron (PH, tetragonal), nanosphere (SP, cubic) and nanoegg (EG, tetragonal), were hydrothermally fabricated. Various physical and chemical techniqueswere used to reveal shape-dependent structural, optical, electronic andsurface properties, providing a powerful insigh...

119.Self-Assembly of Achiral Shape Amphiphiles into Multi-Walled Nanotubes via Helicity-Selective Nucleation and Growth
Soft nanotubes are normally constructed from chiral amphiphiles through helical self-assembly. Yet, how to self-assemble achiral molecules into nanotubes is still a
challenge. Here, we report the nanotube construction with achiral shape amphiphiles through helical self-assembly and also unravel the formation mechanisms. The amphiphiles
have a dumbbell shape and are composed by covalently l...
