Potassium niobate thin films prepared through polymeric precursor method
(Elsevier B.V., 2004-08-01)
Thin films of potassium niobate were deposited on (100) Si substrates by the polymeric precursor method (Pechini method). Annealing in static air was performed at 600degrees C for 20 h. The obtained films were characterized ...

Forced flow of granular media: Breakdown of the Beverloo scaling
(Europhysics Letters, 2018-08)
The Beverloo scaling for the gravity flow of granular materials through orifices has two distinct universal features. On the one hand, the flow rate is independent of the height of the granular column. On the other hand, ...
A functional approach to quantum friction: effective action and dissipative force
(American Physical Society, 2014-04)
We study the Casimir friction due to the relative, uniform, lateral motion of two parallel semitransparent mirrors coupled to a vacuum real scalar field, φ. We follow a functional approach, whereby nonlocal terms in the ...
High-Energy Dissipation Performance in Epoxy Coatings by the Synergistic Effec of Carbon Nanotube/Block Copolymer Conjugate
(American Chemical Society, 2017-01)
Hierarchical assembly of hard/soft nanoparticles holds great potential as reinforcements for polymer nanocomposites with tailored properties. Here, we present a facile strategy to integrate polystyrene-grafted carbon ...
In-flight and collisional dissipation as a mechanism to suppress Fermi acceleration in a breathing Lorentz gas
(American Institute of Physics (AIP), 2012-06-01)
Some dynamical properties for a time dependent Lorentz gas considering both the dissipative and non dissipative dynamics are studied. The model is described by using a four-dimensional nonlinear mapping. For the conservative ...

Testing and performance of a new friction damper for seismic vibration control
(Academic Press Ltd - Elsevier Science Ltd, 2017-07)
In the last two decades, great efforts were carried out to reduce the seismic demand on structures through the concept of energy dissipation instead of increasing the stiffness and strength. Several devices based on different ...
Dissipative model for a gas system with constant external force
(1997)
The thermodynamic characteristics of a system consisting in a mixture of two gases affected by a constant external force (gravity, for example) with dissipation are derived. Assuming a long narrow-square shape pipe container ...
