کاتالیزورهای متالوسن به علت کومونومر پذیری زیاد نسبت به کاتالیزورهای زیگلر ناتا برتری دارند، تحلیل مناسب پارامترهای تاثیرپذیر از شرایط پلیمریزشدن بر محصول نهایی بسیاراهمیت دارد. در این مقاله پارامترهای هزینه، کیفیت، محصول دهی و زمان پخت توسط متخصصان معین و با استفاده از روش AHP وزندهی شدهاند سپس 16 محصول نهایی توس…
Two main types of antifouling coatings are present on the market: - The Self-Polishing Coatings (SPC): they are based on hydrolysable polymer binders and their antifouling efficiency relies on the release of biocides in the marine surrounding. Unfortunately, they are toxic for the marine environment- The Fouling Relea…
The physicochemical properties of a spherical semiconductor nanocrystal, intermediate between the molecule and the solid depend on its size. Stacked or dispersed, these nanocrystals are building blocks of new functional materials with tunable properties, particularly appealing for optoelectronics. This thesis takes pa…
We investigate stationary solutions of a thin-film model for liquid two-layer flows in an energetic formulation that is motivated by its gradient flow structure. The goal is to achieve a rigorous understanding of the contact-angle conditions for such two-layer systems. We pursue this by investigating a corresponding e…
We construct the holographic model of an $S^\pm$ multiband superconductor. This system is a candidate to explain the anomalous features of the iron-based superconductors (e.g. LaFeAsO, BFe2As2, and other pnictides and arsenides). We study the framework, which allows formation of the sign-interchanging order parameter.…
Pd is known to absorb hydrogen. Molecules are normally chemisorbed at the surface in a process where the molecule breaks into two hydrogen atoms, and the protons are then absorbed into the bulk. This process consists of electron filling holes in the Pd 4d band near the Fermi energy, which due to the high density of st…
We present first-principles density functional theory (DFT) investigations of mechanical, thermodynamic and optical properties of synthesized inverse-perovskites Sc3InX (X = B, C, N). The elastic constants at zero pressure and temperature are calculated and the anisotropic behavior of the compounds is illustrated. All…
An accurate description of the heat transfer is essential in the simulation and optimization of processes, the quality of semicrystalline thermoplastic parts is strongly linked to the thermal history during the formatting. Reliable results require a fine knowledge of the thermophysical properties of the polymer. The o…
Using numerical simulations we investigate the dimension evolution of the Stokes-Einstein relation violation in a simple glass forming system. The results strongly support the existence of an upper critical dimension d_u=8 above which the Stokes-Einstein relation is not violated, as predicted by the mean-field theory…
Superconductivity in polycrystalline Fe1+dTe0.9Se0.1 was enhanced by heating in alcoholic beverages. We found that part of the excess Fe was deintercalated from the interlayer sites by the treatment and the shielding volume fractions were increased with the reduction of excess Fe content in sample. This behavior is si…
A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

As vigas de concreto armado perdem capacidade resistente quando em situação de incêndio.A ferramenta mais prática para o dimensionamento dessas peças é o método tabular, apresentado na ABNT NBR 15200:2012, em que a partir do tempo requerido de resistência ao fogo (TRRF) se encontram a largura mínima da seção transvers…
A construction of node-less atomic orbitals and energy-dependent, node-reduced partial waves is presented, that contains the full information of the atomic eigenstates and that allows to represent the scattering properties in a transparent manner. By inverting the defining Schrödinger equation, the Pauli repulsion by…
We report on a systematic study of the structural, magnetic properties and the anomalous Hall effect, in the Heusler alloy Co2FeAl (CFA) epitaxial films on MgO(001), as a function of film thickness. It was found that the epitaxial CFA films show a highly ordered B2 structure with an in-plane uniaxial magnetic anisotro…
We perform a point-contact Andreev reflection spectroscopic study of the topological superconducting material, Cu0.25Bi2Se3, in the ballistic regime using a normal-metal gold tip. We observe distinct point-contact spectra on the superconducting and non-superconducting regions of the crystal surface: the former shows a…
We investigate some connections between the continuum and atomistic descriptions of de- formable crystals, using some interesting results from number theory. The energy of a deformed crystal is calculated in the context of a lattice model with binary interactions in two dimensions. A new bond counting approach is used…
On page 4937 (2nd columm) of the original article1 the sentence “Under temperate conditions, most nerve agents have a low vapour pressure, which means they can evaporate quickly” should be replaced by “Under temperate conditions, most nerve agents have a high vapour pressure, which means they can evaporate quickly”. T…
Water blown biobased thermoplastic polyurethane (TPU) foams were prepared using synthetic and biobased chain extender. The concentration of chain extender, blowing agent (BA) and surfactant were varied and their effects on physical, mechanical and morphological properties of foams were investigated. Density, compressi…
