Tuning photoacoustics with nanotransducers via Thermal Boundary Resistance and Laser Pulse Duration
Michele Diego, Marco Gandolfi, Stefano Giordano +6
The photoacoustic effect in liquids, generated by metal nanoparticles excited with short laser pulses, offers high contrast imaging and promising medical treatment techniques. Unde…
Infinite ergodicity for geometric Brownian motion
Stefano Giordano, Fabrizio Cleri, Ralf Blossey
Geometric Brownian motion is an exemplary stochastic processes obeying multiplicative noise, with widespread applications in several fields, e.g. in finance, in physics and biology…
Thermal effects on fracture and brittle-to-ductile transition
Andrea Cannizzo, Stefano Giordano
The fracture behavior of brittle and ductile materials can be strongly influenced by thermal fluctuations, especially in micro- and nano-devices as well as in rubberlike and biolog…
Thermal control of nucleation and propagation transition stresses in discrete lattices with non-local interactions and non-convex energy
Andrea Cannizzo, Luca Bellino, Giuseppe Florio +2
Non-local and non-convex energies represent fundamental interacting effects regulating the complex behavior of many systems in biophysics and materials science. We study one dimens…
Stiffening of nanoporous Au as a result of dislocation density increase upon characteristic length reduction
Claudio Melis, Giorgio Pia, Elisa Sogne +4
Structure is the most distinctive feature of nanoporous metals. The intricate maze of rounded shapes, where ligaments and pores run after each other disorderly, strikes imagination…
Density functional theory calculations of the stress of oxidised (110) silicon surfaces
C Melis, S Giordano, L Colombo +1
The measurement of the lattice-parameter of silicon by x-ray interferometry assumes the use of strain-free crystals. This might not be the case because surface relaxation, reconstr…
Generalized interface models for transport phenomena: unusual scale effects in composite nanomaterials
Fabio Pavanello, Fabio Manca, Pier Luca Palla +1
The effective transport properties of heterogeneous nanoscale materials and structures are affected by several geometrical and physical factors. Among them the presence of imperfec…
Theory and Monte Carlo simulations for the stretching of flexible and semi-flexible single polymer chains under external fields
Fabio Manca, Stefano Giordano, Pier Luca Palla +2
Recent developments of microscopic mechanical experiments allow the manipulation of individual polymer molecules in two main ways: \textit{uniform} stretching by external forces an…
Theory of single-molecule experiments in the overstretching force regime
Fabio Manca, Stefano Giordano, Pier Luca Palla +2
We present a statistical mechanics analysis of the finite-size elasticity of biopolymers, consisting of domains which can exhibit transitions between more than one stable state at…
Elastic properties of hydrogenated graphene
Emiliano Cadelano, Pier Luca Palla, Stefano Giordano +1
There exist three conformers of hydrogenated graphene, referred to as chair-, boat-, or washboard-graphane. These systems have a perfect two-dimensional periodicity mapped onto the…
A lattice model describing scale effects in nonlinear elasticity of nano-inhomogeneities
Pier Luca Palla, Stefano Giordano, Luciano Colombo
We present a procedure to map the constitutive laws of elasticity (both in the linear and nonlinear regime) onto a discrete atomic lattice and we apply the resulting elastic lattic…
Interplay between bending and stretching in carbon nanoribbons
Emiliano Cadelano, Stefano Giordano, Luciano Colombo
We investigate the bending properties of carbon nanoribbons by combining continuum elasticity theory and tight-binding atomistic simulations. First, we develop a complete analysis…
Nonlinear elasticity of monolayer graphene
Emiliano Cadelano, Pier Luca Palla, Stefano Giordano +1
By combining continuum elasticity theory and tight-binding atomistic simulations, we work out the constitutive nonlinear stress-strain relation for graphene stretching elasticity a…
The photospheric environment of a solar pore with light bridge
S. Giordano, F. Berrilli, D. Del Moro +1
Pores are one of the various features forming in the photosphere by the emergence of magnetic field onto the solar surface. They lie at the border between tiny magnetic elements an…
