Granular Flows in a Rotating Drum: the Scaling Law between Velocity and Thickness of the Flow

, 2006
The flow of dry granular material in a half-filled rotating drum is studied. The thickness of the flowing zone is measured for several rotation speeds, drum sizes and beads sizes (size ratio between drum and beads ranging from 47 to 7400).

4D Printing of Self‐Immolative Polymers

Advanced Functional Materials, EarlyView.
The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Growth laws and self-similar growth regimes of coarsening two-dimensional foams: Transition from dry to wet limits

, 2012
We study the topology and geometry of two dimensional coarsening foams with arbitrary liquid fraction. To interpolate between the dry limit described by von Neumann's law, and the wet limit described by Marqusee equation, the relevant bubble ...

Electron–Matter Interactions During Electron Beam Nanopatterning

Advanced Functional Materials, EarlyView.
This article reviews the electron–matter interactions important to nanopatterning with electron beam lithography (EBL). Electron–matter interactions, including secondary electron generation routes, polymer radiolysis, and electron beam induced charging, are discussed.

Use of mathematical laws for optimizing the doses of swelled and dry bentonite during the fining of white wines. Part I: clarification and colloidal stability

OENO One, 2002
White wine clarity is of prime importance for the winemaker as a bottle showing haziness is likely to be rejected by the consumer. It is then important to ensure a perfect colloidal stability to the wine.

The SINFONI Black Hole Survey: The Black Hole Fundamental Plane revisited and the paths of (co-) evolution of supermassive black holes and bulges

, 2016
We investigate the correlations between the black hole mass $M_{BH}$, the velocity dispersion $\sigma$, the bulge mass $M_{Bu}$, the bulge average spherical density $\rho_h$ and its spherical half mass radius $r_h$, constructing a database of 97 galaxies

A “lei seca” eleitoral: Reflexões sobre cultura e controle na sociedade brasileira

Dilemas: Revista de Estudos de Conflito e Controle Social, 2009
A “lei seca” eleitoral consiste em uma norma jurídica do Estado para proibir a comercialização de bebidas alcoólicas em dias de procedimentos eleitorais. Sua existência se justifi caria pela preservação da segurança e da legitimidade das eleições.
