Powder diffraction patterns from cylindrically oriented nanocrystals

Norberto Masciocchi, Federica Bertolotti, Pietro Anzini, F. Ferri

The Debye Scattering Equation (DSE) has been recently inserted in a number of powerful software packages capable of characterizing the structure and microstructure of 3D randomly oriented nanocrystals, like colloidal quantum dots and other nanomaterials in a powdered form. When, instead, well-faceted …

Thermo-osmotic flows in closed channels

Matteo Bessega, Pietro Anzini, Alberto Parola

Thermal forces are an elusive phenomenon in the realm of out of equilibrium statistical physics. Fluids confined in nanochannels, pores, or membranes can be efficiently set into motion by thermal gradients. Confinement is essential to trigger this effect, known as thermo-osmosis, leading …

Temperature-driven flows in nanochannels: Theory and simulations

Pietro Anzini, Zeno Filiberti, Alberto Parola

The motion of a fluid induced by thermal gradients in the absence of external forces is known as thermo-osmosis. The physical explanation of this phenomenon stems from the emergence of gradients in the tangential pressure due to the presence of a confining …

Site-occupancy factors in the Debye scattering equation. A theoretical discussion on significance and correctness

F. Ferri, Maria Chiara Bossuto, Pietro Anzini, Antonio Cervellino et autres

The Debye scattering equation (DSE) [Debye (1915). Ann. Phys. 351, 809-823] is widely used for analyzing total scattering data of nanocrystalline materials in reciprocal space. In its modified form (MDSE) [Cervellino et al. (2010). J. Appl. Cryst. 43, 1543-1547], it includes contributions …

Variance analysis of dynamic light scattering data

Pietro Anzini, Davide Biganzoli, Ihor Cherniukh, Maksym V. Kovalenko et autres

We propose a novel method alternative to the classical Dynamic Light Scattering (DLS) technique for performing particle sizing on diluted dispersions of nanosized particles. Differently from DLS, which works by determining the correlation function of the intensity scattered by the sample, our …
