Phase diagrams of Janus fluids with up-down constrained orientations.

Global phase diagrams for dipolar fluids.

Fluids of molecules or particles interacting through dipole forces describe polar liquids and colloidal suspensions such as ferroQuids and electrorheological fluids. Phase diagrams for systems with strong dipolar coupling are not precisely known. Possible liquid state phase transitions include phase separation and spontaneous polarization. We present a set of generic phase diagrams for the Huid...

Janus fluid with fixed patch orientations: theory and simulations.

We study thermophysical properties of a Janus fluid with constrained orientations, using analytical techniques and numerical simulations. The Janus character is modeled by means of a Kern-Frenkel potential where each sphere has one hemisphere of square-well and the other of hard-sphere character. The orientational constraint is enforced by assuming that each hemisphere can only point either Nor...

Mixing Times of Markov Chains on Degree Constrained Orientations of Planar Graphs

We study Markov chains for α-orientations of plane graphs, these are orientations where the outdegree of each vertex is prescribed by the value of a given function α. The set of α-orientations of a plane graph has a natural distrubutive lattice structure. The moves of the up-down Markov chain on this distributive lattice corresponds to reversals of directed facial cycles in the α-orientation. W...

Phase diagrams of Bi1−xSbx thin films with different growth orientations

Deconvoluted Si 2p Photoelectron Spectra of Ultra thin SiO2 film with FitXPS method

The main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. The obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...
