We consider the Asakura–Oosawa–Vrij model of hard sphere colloids and ideal polymer coils in contact with a planar hard wall at (colloidal) liquid–gas coexistence. Using extensive numerical density functional calculations, the liquid–gas, wall–liquid and wall–gas interfacial free energies are calculated. The results are inserted into Young’s equation to obtain the contact angle between the liqu...

In a recent paper with Bousquet-Mélou, de Gier, Duminil-Copin and Guttmann (2012), we proved that a model of self-avoiding walks on the honeycomb lattice, interacting with an impenetrable surface, undergoes an adsorption phase transition when the surface fugacity is 1 + √ 2. Our proof used a generalisation of an identity obtained by Duminil-Copin and Smirnov (2012), and confirmed a conjecture o...

This article contributes to the development of a thermodynamic model for simulating CO2 solubility in pure water and aqueous brines under different conditions temperature, pressure ionic strength. The modeling activity-fugacity (?-?) approach allows calculating solubility, based on Pitzer electrolyte theory activity coefficient Peng-Robinson's equation state fugacity. present work proposes new ...

We consider two-component fermions with a zero-range interaction both in two and three dimensions calculate the bulk viscosity for an arbitrary scattering length high-temperature regime. evaluate Kubo formula using expansion respect to fugacity, which acts as small parameter at high temperatures. In zero-frequency limit of formula, pinch singularities emerge that reduce order fugacity by one. T...

Synopsis: The oxygen fugacity of the basaltic martian meteorites has been calculated from thermodynamic models involving spinel-ilmenite equilibria. The wide range of estimates, from near the IW buffer to near QFM, may be explained by mixing of mantlederived melts with oxidized material in the martian crust. Possible oxidized crustal end-members are considered. Analytical Method and Results: Sp...

OBJECTIVE OPA1 mutations cause protein haploinsufficiency leading to dominant optic atrophy (DOA), an incurable retinopathy with variable severity. Up to 20% of patients also develop extraocular neurological complications. The mechanisms that cause this optic atrophy or its syndromic forms are still unknown. After identifying oxidative stress in a mouse model of the pathology, we sought to dete...

We present the detection of molecular oxygen with Odin toward the dense molecular core ρ Oph A, which is part of a region of active star formation. The observed spectral line is the (NJ = 11 − 10) ground state transition of O2 at 119 GHz (2.5 mm wavelength). The center of the line is at the LSR velocity of a number of optically thin lines from other species in the region and the O2 line also ha...

Material and Methods C57/BL6 and ApoE-/mice (n=6 per group) were evaluated using a horizontal bore 9.4 T MRI animal scanner (Bruker, Karlsruhe, Germany) with a dedicated 2x2 phased-array surface coil. All MRI experiments were performed during general anesthesia using a mixture of isoflurane (2%) and oxygene (98%) applied by a mask covering nose and mouth of the animals. For cine imaging of the ...
