Biocomposite matrices with high mechanical strength, high stability, and the ability to direct matrix-specific stem cell differentiation are essential for the reconstruction of lesioned tissues in tissue engineering and cell therapeutics. Toward this end, we used the electrospinning technique to fabricate well-aligned composite fibers from collagen and spider dragline silk protein, obtained fro...

2014 SANS in metallic glasses is anisotropic and depends on the orientation of the ribbons. Pd-based melt-spun and Nibased electrochemically deposited glasses exhibit different anisotropies. Both glasses contain scattering centres of the order of 40 nm wide in the ribbon plane. In the melt-spun alloy, the scatterers are very thin along the thickness perpendicular to the substrate. In the deposi...

Based on X-ray diffraction, microscopic and magnetic analysis, the structure and magnetic properties of Co77Zr18W5 melt-spun ribbons were studied in this paper. A new element to stabilize the metastable Co5Zr phase was found and the coercivity observed in Co-Zr alloys can be obviously enhanced by proper tungsten substitution. The Curie temperature of Co77Zr18W5 ribbons is 475 ̊C which suggests t...

High-speed melt spinning of a cyclo-olefin polymer (COP) and a copolyamide (CoPA) have been performed. Differential scanning calorimetry curves of the resulting monofilaments show that they remain in an amorphous state even after hot drawing. Wide angle x-ray diffraction patterns of undrawn and drawn COP filaments show that although the material remains in an amorphous state, a degree of orient...

We give a simple sufficient condition for a spun-normal surface in an ideal triangulation to be incompressible, namely that it is a vertex surface with nonempty boundary which has a quadrilateral in each tetrahedron. While this condition is far from being necessary, it is powerful enough to give two new results: the existence of alternating knots with noninteger boundary slopes, and a proof of ...

The Legendrian product of two knots, as defined by Lambert-Cole, is a torus. We show that this torus twist spun whenever one the knot components sufficiently large. then study examples products which are not isotopic to spuns. In order do this, we prove few structural results on bilinearised contact homology and augmentation variety spun. addition, threefold Bohr-Sommerfeld covers Clifford Chek...

Yoshida in [6] and Tillmann in [3] describe di erent methods of producing surfaces within a 3-manifoldM with boundary from ideal points of the deformation variety of M , given a particular ideal tetrahedralisation of M . The Yoshida construction builds a surface from twisted squares within the tetrahedra, the Tillmann construction results in a spun-normal surface relative to the tetrahedra. In ...

Optimization of spin-coat parameters of a spin-ondielectric (SOD) onto a substrate is investigated using a two level fractional factorial design of experiment. Five parameters, spin rate, spin time, number of spin coats, volume of SOD, and the softbake temperature were varied to determine the main effect on the thickness of the deposited layers as a quality check. The layer thickness was measur...
