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 […]

Soret effect and photochemical reaction in liquids with laser-induced local heating

Luis C. Malacarne, Nelson G. Castelli Astrath, Antonio Medina Neto, Leandro S. Herculano, Mauro L. Baesso, Paulo R. Borba Pedreira, Jun Shen, Q. Wen, Kirk H. Michaelian e Craig Fairbridge

Optics Express – Volumu: 19; Issue: 5; Pages: 4047-4058; DOI: 10.1364/OE.19.004047; 2011

We report a theoretical model and experimental results for laser-induced local heating in liquids, and […]

Nanoscale surface displacement detection in high absorbing solids by time-resolved thermal mirror

Luis C. Malacarne, Francielle Sato, Paulo R. Borba Pedreira, Antonio C. Bento, Renio S. Mendes, Mauro L. Baesso, Nelson G. Castelli Astrath e Jun Shen

Applied Physics Letters – Volume: 92; Issue: 13; Number article: 131903; DOI: 10.1063/1.29052612008; 2008

Nanoscale surface displacement is used to determine thermo-optical–mechanical properties of high absorbing solids by means of the time-resolved […]
