Linear viscoelasticity of styrenic block copolymers-clay nanocomposites
(SPRINGER, 2008)
In this work, the rheological behavior of block copolymers with different morphologies (lamellar, cylindrical, spherical, and disordered) and their clay-containing nanocomposites was studied using small amplitude oscillatory ...
Entropic Entanglement Criteria for Fermion Systems
(Springer, 2012-01)
Entanglement criteria for general (pure or mixed) states of systems consisting of two identical fermions are introduced. These criteria are based on appropriate inequalities involving the entropy of the global density ...
Fases geométricas e invariantes dinâmicos em mecânica quântica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2007-05-16)
The increasing interest to understand the geometric phases (mainly due to the possi-
bility to achieve geometric quantum computation robust against some kind of errors) and
the search for new techniques to solve time-dependent ...
Stochastic processes applied to classical physics and quantum mechanics
(UniandesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2010)
The dynamics in physical systems when subject to environmental fluctuations is usually described by ensemble averages, providing information on the probability of the described system to reside in a possible state. Classical ...
Electrochemical studies of copper-aluminum-silver alloys in 0.5 M H2SO4
(Elsevier B.V., 2001-01-15)
The electrochemical behavior in 0.5 M H2SO4 at 25 degreesC of a Cu-Al(9.3 wt%)-Ag(4.7 wt%) alloy submitted to different heat treatments and an annealed Cu- Al(9.7 wt%)-Ag(34.2 wt%) were studied by means of open circuit ...

Ti-Mo cast alloys for biomedical applications. Anodic behavior and passive film properties
(2010-12-01)
Casting of Ti-Mo alloys having different Mo content (4 to 20 wt%) was performed by arcmelting of pure metals. These alloys present interesting features for potential biomedical applications, e.g., in artificial proteases, ...
Preparation, characterization and taste sensing properties of Langmuir-Blodgett Films from mixtures of polyaniline and a ruthenium complex
(Elsevier B.V., 2003-07-01)
Langmuir-Blodgett (LB) films from a ruthenium complex, mer-[RuCl3(dppb)(py)] (dppb = PPh2(CH2)(4)PPh2; py = pyridine) (Rupy), and from mixtures with varied amounts of polyaniline (PANi) were fabricated. Molecular-level ...

Majorization, across the (quantum) universe
(Cambridge University Press, 2019)
In how many ways can one represent a given quantum mixed state as a mixture of pure states? Why (and in which sense) are separable states more disordered globally than locally? Is it possible to transform a given pure state ...
