International Photoacoustic and Photothermal Association (IPPA) Junior Prize for Prof. Nelson G. C. Astrath

Prof. Nelson Astrath received the IPPA Junior Prize for outstanding experimental and theoretical contributions to the development of different photothermal methods, the mode mismatched thermal mirror technique in particular, which has substantially enhanced material research in general, and the study of photochemical and photophysics processes in liquids in particular. For his contribution to the experimental […]

Elastic continuum theory: Towards understanding of the twist-bend nematic phases

G. Barbero, L. R. Evangelista, P. Rosseto R. S. Zola e I. Lelidis

PHYSICAL REVIEW E – Volume: 92; Number article: 030501; DOI: 10.1103/PhysRevE.92.030501; 2015

The twist-bend nematic phase, NTB , may be viewed as a heliconical molecular arrangement in which the director n precesses uniformly about an extra director field, t. It corresponds to a nematic ground […]

The advantage of playing home in NBA: microscopic, team-specific and evolving features

Haroldo V. Ribeiro, Satyam Mukherjee e Xiao Han T. Zeng

PLoS ONE (Accepted, 2016)

The idea that the success rate of a team increases when playing home is broadly accepted and documented for a wide variety of sports. Investigations on the so-called “home advantage phenomenon” date back to the 70′s and every since has attracted the attention […]

Transient superdiffusion and long-range correlations in the motility patterns of trypanosomatid flagellate protozoa

L. G. A. Alves, D. B. Scariot, R. R. Guimarães, C. V. Nakamura, R. S. Mendes e H. V. Ribeiro

PLoS ONE (Accepted, 2016)

We report on a diffusive analysis of the motion of flagellate protozoa species. These parasites are the etiological agents of neglected tropical diseases: leishmaniasis caused by Leishmania amazonensis and Leishmania braziliensis, African sleeping […]

We report on a large-scale characterization of river discharges by employing the network framework of the horizontal […]

San Giorgio Prize for Prof. Luiz Roberto Evangelista

Prof. Luiz Roberto Evangelista awarded the prize San Giorgio per Distinzione Accademica, Centro Studi Molisano, Campobasso (Italy). Prof. Evangelista is a physicist and a distinguished academic of international reputation. He was born in Maringa, Parana, Brazil, on March 2, 1958. His great-grandparents were from Molise and arrived in Brazil in the late nineteenth century (1897).


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 […]
