Analogies Between the Cracking Noise of Ethanol-Dampened Charcoal and Earthquakes

Haroldo V. Ribeiro, Leandro S. Costa, Luiz G. Andrade Alves, Perseu A. Santoro, Sergio de Picoli Jr., Ervin K. Lenzi e Renio S. Mendes

Physical Review Letters – Volume: 115; Issue: 2; Article Number: 025503; DOI: 10.1103/PhysRevLett.115.025503; 2015

We report on an extensive characterization of the cracking noise produced by charcoal samples when dampened with ethanol. We argue that the evaporation of ethanol causes […]

Unusual diffusing regimes caused by different adsorbing surfaces

Veridiana G. Guimarães, Haroldo V. Ribeiro, Quan Li, Luiz R. Evangelista, Ervin K. Lenzi e Rafael S. Zola

Soft Matter – Volume: 11; Issue: 9; Pages: 1658-1666; DOI: 10.1039/C5SM00151J; 2015

A confined liquid with dispersed neutral particles is theoretically studied when the limiting surfaces present different dynamics for the adsorption–desorption phenomena. The investigation considers different non-singular kernels in […]

Light-Directing Omnidirectional Circularly Polarized Reflection from Liquid-Crystal Droplets

Jing Fan, Yannian Li, Hari Krishna Bisoyi, Rafael S. Zola, Deng-ke Yang, Timothy J. Bunning, David A. Weitz e Quan Li

Angewandte Chemie International Edition – Volume: 54; Issue: 7; Pages: 2160–2164; 2015

Constructing and tuning self-organized three-dimensional (3D) superstructures with tailored functionality is crucial in the nanofabrication of smart molecular devices. Herein we fabricate a self-organized, […]

Unravelling the effects of radiation forces in water

Nelson G. C. Astrath, Luis C. Malacarne, Mauro L. Baesso, Gustavo V. B. Lukasievicz e Stephen E. Bialkowski

Nature Communications – Volume: 5; Article number: 4363; DOI:10.1038/ncomms5363; 2014

The effect of radiation forces at the interface between dielectric materials has been a long-standing debate for over a century. Yet there has been so far only limited experimental verification […]

Distance to the Scaling Law: A Useful Approach for Unveiling Relationships between Crime and Urban Metrics

Luiz G. de Andrade Alves, Haroldo V. Ribeiro , Ervin K. Lenzi e Renio dos S. Mendes

PLOS ONE – Volume: 8; Issue: 8; Article Number: e69580; DOI: 10.1371/journal.pone.0069580; 2013

We report on a quantitative analysis of relationships between the number of homicides, population size and ten other urban metrics. By using data from Brazilian cities, we […]

Surface Induced Phase Separation and Pattern Formation at the Isotropic Interface in Chiral Nematic Liquid Crystals

Rafael S. Zola, Luiz R. Evangelista, Y.-C Yang e D.-K. Yang

Physical Review Letters – Volume: 110; Issue: 5; Article Number: 057801; DOI: 10.1103/PhysRevLett.110.057801; 2013

We study the pattern formation of a chiral nematic liquid crystal under a wetting transition. In the isotropic-liquid crystal transition, a surface-enhanced effect happens and a thin liquid crystal layer forms at […]

Scale-invariant structure of size fluctuations in plants

Sergio Picoli Jr., Renio S. Mendes, Ervin K. Lenzi e Luis C. Malacarne

Scientific Reports – Volume: 2; Article number: 328; DOI: 10.1038/srep00328; 2012

A wide range of physical and biological systems exhibit complex behaviours characterised by a scale-invariant structure of the fluctuations in their output signals. In the context of plant populations, scaling relationships are typically […]
