“…Modifications of starch lead to more economic and efficient application in the paper industry and also protect the environment [5][6][7][8]. Recently, investigations were focused on composites based on starch and clay minerals, especially phyllosilicates [9][10][11][12][13][14][15] Sepiolite [Si 12 Mg 8 O 30 (OH) 4 (OH 2 ) 4 Á 8H 2 O] is a natural, fibrous clay mineral having a large specific surface area and high porosity [16]. The unique fibrous structure of sepiolite is formed by blocks and interior channels along the fiber direction.…”

The modern and rapidly developing paper and board industry requires more efficient agents for the surface of paper in order to improve the mechanical properties. The starch coating used for the reinforcement of schrenz (110 g/m 2 ) contained ultrasonicated nanoparticles of the mineral sepiolite. The viscosity of starch dispersions modified with different concentration of sepiolite was followed at the temperature of the coating on schrenz. The values of the breaking length, bursting strength and CMT-strength of the paper reinforced with modified starch were increased by up to 20%. The viscoelastic properties as storage modulus were increased, too. Scanning electron microscopy of the samples showed deagglomeration and homogeneity of the sepiolite nanoparticles.

“…They found that PVP had a restrain effect on the crystallization of PCL and the hydrophilic properties of PCL/PVP blends were improved compared with pure PCL . Moreover, compounding PCL with layer silicate, carbon nanotubes, or fumed silica has been widely investigated. For example, in previous research, PCL/silica nanocomposites were prepared by melt compounding.…”

In this work, stereocomplex-poly(L-and D-lactide) (sc-PLA) was incorporated into poly(e-caprolactone) (PCL) to fabricate a novel biodegradable polymer composite. PCL/sc-PLA composites were prepared by solution casting at sc-PLA loadings of 5-30 wt %. Differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) demonstrated the formation of the stereocomplex in the blends. DSC and WAXD curves also indicated that the addition of sc-PLA did not alter the crystal structure of PCL. Rheology and mechanical properties of neat PCL and the PCL/sc-PLA composites were investigated in detail. Rheological measurements indicated that the composites exhibited evident solid-like response in the low frequency region as the sc-PLA loadings reached up to 20 wt %. Moreover, the long-range motion of PCL chains was highly restrained. Dynamic mechanical analysis showed that the storage modulus (E 0 ) of PCL in the composites was improved and the glass transition temperature values were hardly changed after the addition of sc-PLA. Tensile tests showed that the Young's modulus, and yield strength of the composites were enhanced by the addition of sc-PLA while the tensile strength and elongation at break were reduced.

“…Central to the present discussion are recent fundamental improvements in the understanding of the internal geometry and topology of ends of hyperbolic 3-manifolds. Via the Ending Lamination Theorem of [52,18] and the model manifold developed in its proof, the Tameness Theorem of [1,26] and the Density Theorem [18,54,58], we develop a more complete picture of the topological complexity at the boundary of deformation spaces.…”

“…A point ρ ∈ ∂AH(M ) is said to be uniquely approachable if there is no bumping or self-bumping at ρ. The Density Theorem [18,54,58] asserts that AH(M ) is the closure of its interior, so AH(M ) is locally connected at all uniquely approachable points. Theorem 1.1.…”

We prove that the deformation space AH.M / of marked hyperbolic 3-manifolds homotopy equivalent to a fixed compact 3-manifold M with incompressible boundary is locally connected at minimally parabolic points. Moreover, spaces of Kleinian surface groups are locally connected at quasiconformally rigid points. Similar results are obtained for deformation spaces of acylindrical 3-manifolds and Bers slices. 30F40; 57M50
