Hybrid poly(ϵ-caprolactone) (PCL) containing nanocomposites and non-hybrid linear PCL diols were synthesized by anionic ring opening polymerization of ϵ-caprolactone on a POSS or ethylene glycol central blocks, respectively. Monolith scaffolds were then fabricated from the hybrid nanocomposites and non-hybrid linear P…
Application of the directed self-assembly (DSA) of block copolymer (PS-b-PMMA) to the hole shrink process has gained large attention because of the low cost and the potential for sub-lithographic patterning of contact, via and cut masks (Ref. [1-2] and references therein). In order to realize the DSA hole shrink proce…
Crystal quality during Czochralski (Cz) growth is influenced significantly by the convexity of solid/liquid (S/L) interface, which is related to operating conditions, such as Radio‐Frequency (RF) coil position, crystal rotation and crucible rotation. Generally, a flat interface shape is preferred for high‐quality crys…
Real-time monitoring of optical anisotropy during growth by the chemical mist deposition of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films was carried out using spectroscopic ellipsometry. The microstructure of the grown films was found to be primarily determined by the DC bias applied to th…
Corrosion behaviours of low alloy steels with various alloying element contents were studied in simulated corrosion environment (pH = 0·85, 10% NaCl solution) of cargo oil tank (COT) bottom plate corrosion environment. Corrosion rate was measured, and the surface morphology of test steels was characterised using scann…
Three quasi-binary phase systems, BiSX(1 - x)Y(x) (X, Y = Cl, Br, I; 0 < x < 1), have been investigated by X-ray powder diffraction. All three systems show unlimited solubility. For BiSCl(1 - x)Br(x) and BiSCl(1 - x)I(x), strong positive and negative deviations from Vegard's rule are observed with respect to the latti…
The oxide series La2−xSrxCoTiO6(0 ≤x≤ 1.0) belong to the perovskite family with general formulaABO3. The evolution of the room-temperature structure as a function of the Sr content was studied using complementary techniques by applying the symmetry-adapted modes formalism (AMPLIMODES). In the compositional range prese…
The Ampère law is useful to calculate the magnetostatic field in the cases of distributions of current with high degree of symmetry. Nevertheless the magnetic field produced by a thin straight wire carrying a current I requires the Biot–Savart law and the use of the Ampère law leads to a mistake. A didactical formulat…
The thermal, mechanical, and adhesive properties of nanoclay-modified adhesives were investigated. Two organically modified montmorillonites: Cloisite 93A (C93A) and Nanomer I.30E (I.30E) were used as reinforcement of an epoxy adhesive. C93A and I.30E are modified with tertiary and primary alkyl ammonium cations, resp…
We present a study of the crystallization process in liquid vanadium over a temperature range from 3000 K down to 1500 K using ab initio molecular dynamics simulations. Short-range order evolution during solidification is studied using various structural analysis methods. We show that the icosahedral-like short-range…
We fabricated ZnO/SiN films for use as a light source of a high-resolution optical microscope and characterized the properties of the films, and demonstrated images obtained with the microscope using the fabricated ZnO/SiN films. A 100-nm-thick ZnO film deposited on a SiN film showed a much higher CL intensity than th…
In this paper we propose a new class of coupling methods for the sensitivity analysis of high dimensional stochastic systems and in particular for lattice Kinetic Monte Carlo (KMC). Sensitivity analysis for stochastic systems is typically based on approximating continuous derivatives with respect to model parameters b…
Surface functionalization of inorganic nanomaterials through chemical binding of organic ligands on the surface unsaturated atoms, forming unique organic-inorganic interfaces, is a powerful approach for creating special functions for inorganic nanomaterials. Herein, we report the synthesis of hierarchical MgO nanocrys…
Vibration characteristics of metamaterial structures manufactured of assemblies of periodic cells with built-in local resonances are presented. Each cell consists of a base structure provided with cavities filled by a viscoelastic membrane that supports a small mass to form a source of local resonance. This class of m…
The tuning of nanostructure plasmon resonances with bridging molecules offers opportunities for both plasmonics and molecular electronics. [Also see Research Article by Tan et al. ]
PURPOSE: To evaluate the use of endoglin-targeted paramagnetic liposomes in delineating the glioma margins using magnetic resonance (MR) angiogenesis imaging in a rat model. MATERIALS AND METHODS: Four liposome preparations, including nontargeted paramagnetic liposomes (Gd-SLs), isotype control IgG-coupled paramagneti…
Quantitative information on the charge and stress profile during partial discharges (PDs) is required in order to discuss and clarify the process of electrical degradation in solids. Such PDs cause cavities to grow. Therefore, we have proposed a procedure for analysing discharges within cavities, based on motion obser…
There are many examples in nature where inorganic and organic phases are intricately connected to each other, both in form and function. Mineral phases impart increased mechanical strength as well as biological‐, chemical‐ and thermal resistance to natural organic structures. This is achieved by the provision of compl…
Resonant x-ray diffraction was used to study the proton jumps in hydrogen-bonded rubidium dihydrogen phosphate (RDP) crystals. In the paraelectric RDP phase, hydrogen is delocalized between two crystallographically equivalent positions. At lower temperatures, this symmetry can be broken, which defines the processes th…
The nature of charge disproportionation in orthorhombic lanthanum orthoferrites La1-xCaxFeO3-δ (x = 0.4 and 0.5) has been investigated by kilohertz mechanical spectroscopy. Contrast to rhombohedral La1-xSrxFeO3-δ (x = 0.5), no elastic softening was observed in La1-xCaxFeO3-δ above charge disproportionation. This diffe…
