PMID: 20596386
Nanoscale Res Lett. 2009 Jan 06;4(3):262-8. doi: 10.1007/s11671-008-9235-0.

Dynamic scaling behavior has been observed during the room-temperature growth of sputtered Au films on SiO2using the atomic force microscopy technique. By the analyses of the dependence of the roughness, σ, of the surface roughness power,P(f), and of the...

This article derives from a society-wide symposium organized by Timothy Bradley and Adriana Briscoe and presented at the 2009 annual meeting of the Society for Integrative and Comparative Biology in Boston, Massachusetts. David Grimaldi provided the opening presentation in...

Optimal percolation of disordered segregated composites.

Physical review. E, Statistical, nonlinear, and soft matter physics

Johner N, Grimaldi C, Maeder T, Ryser P.
PMID: 19391696
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Feb;79(2):020104. doi: 10.1103/PhysRevE.79.020104. Epub 2009 Feb 24.

We evaluate the percolation threshold values for a realistic model of continuum segregated systems, where random spherical inclusions forbid the percolating objects, modeled by hardcore spherical particles surrounded by penetrable shells, to occupy large regions inside the composite. We...

Novel approach to the fabrication of Au/silica core-shell nanostructures based on nanosecond laser irradiation of thin Au films on Si.

Nanotechnology

Ruffino F, Pugliara A, Carria E, Romano L, Bongiorno C, Spinella C, Grimaldi MG.
PMID: 22214877
Nanotechnology. 2012 Feb 03;23(4):045601. doi: 10.1088/0957-4484/23/4/045601. Epub 2012 Jan 04.

We demonstrate the possibility of producing Au/SiO(2) core-shell nanoparticles by nanosecond laser irradiation of thin (5 and 20 nm) Au films on Si. The Au/Si eutectic reaction and dewetting process caused by the fast melting and solidification dynamics induced...

Quasiuniversal connectedness percolation of polydisperse rod systems.

Physical review letters

Nigro B, Grimaldi C, Ryser P, Chatterjee AP, van der Schoot P.
PMID: 23383806
Phys Rev Lett. 2013 Jan 04;110(1):015701. doi: 10.1103/PhysRevLett.110.015701. Epub 2013 Jan 02.

The connectedness percolation threshold (η(c)) and critical coordination number (Z(c)) of systems of penetrable spherocylinders characterized by a length polydispersity are studied by way of Monte Carlo simulations for several aspect ratio distributions. We find that (i) η(c) is...

The termites of Early Eocene Cambay amber, with the earliest record of the Termitidae (Isoptera).

Zookeys. 2011;(148):105-23. doi: 10.3897/zookeys.148.1797. Epub 2011 Nov 21.

The fauna of termites (Isoptera) preserved in Early Eocene amber from the Cambay Basin (Gujarat, India) are described and figured. Three new genera and four new species are recognized, all of them Neoisoptera - Parastylotermes krishnai Engel & Grimaldi,...

Influence of hydroclimatic variations on solute concentration dynamics in nested subtropical catchments with heterogeneous landscapes.

The Science of the total environment

Piazza GA, Dupas R, Gascuel-Odoux C, Grimaldi C, Pinheiro A, Kaufmann V.

Despite global efforts to monitor water quality in catchments worldwide, tropical and subtropical zones still lack data to study the influence of human activities and climate variations on solute dynamics. In this study, we monitored ten solutes every two...

Personal genetics, the European regulations maze and the way out.

Sci Rep. 2019 Mar 14;9(1):4591. doi: 10.1038/s41598-019-40997-6.

Standard imaging systems provide a spatial resolution that is ultimately dictated by the numerical aperture (NA) of the illumination and collection optics. In biological tissues, the resolution is strongly affected by scattering, which limits the penetration depth to a...
