A thermodynamic property model explicit in the Helmholtz energy is presented for the R-134a/245fa mixtures. A multi-fluid approximation based on pure-fluid Helmholtz energy equations of state forms the basis of the property model. The Helmholtz energy of the mixture is expressed as the sum of the ideal gas contribution, the compressibility contribution (real fluid contribution), and the contrib...

We conduct a rigorous investigation into the thermodynamic instability of ideal Bose gas confined in a cubic box. Based on the exact expression of canonical partition function, we perform numerical computations up to the number of particles one million. We report that if the number of particles is equal to or greater than 7616, the ideal Bose gas subject to Dirichlet boundary condition reveals ...

Aiming to contribute drug pre-formulation, new eutectic mixtures were developed. Thymol, coumarin, or quaternary ammonium chlorides as excipients, combined with the active pharmaceutical ingredients (APIs) acetylsalicylic acid, acetaminophen, ibuprofen, ketoprofen, lidocaine. Their solid-liquid equilibrium (SLE) binary phase diagrams measured study eventual separation between compounds, prevent...

the complexation reaction between hydroxyl ammonium (honh3+ ) cation with 18-crown-6 (18c6) ligand was studied in dimethylsulfoxide – water (dmso-h2o), methanol – water (meoh-h2o) and dimethylformamid – methanol (dmf-meoh), binary solutions at different temperatures using conductometric method. the obtained results show that the stoichiometry of the complex formed between honh3+ cation with (18...

Deep eutectic solvents (DESs) have emerged as a cheaper and greener alternative to conventional organic solvents. Choline chloride (ChCl) mixed with urea at molar ratio of 1:2 is one the most common DESs for wide range applications such electrochemistry, material science, biochemistry. In this study, molecular dynamics simulations are performed study effect content on thermodynamic transport pr...

Semi-device-independent random number expansion (SDI-RNE) protocols require some truly random numbers to generate fresh ones, with making no assumptions on the internal working of quantum devices except for the dimension of the Hilbert space. The generated randomness is certified by non-classical correlation in the prepare-and-measure test. Until now, the analytical relations between the amount...

The aim of this paper is to study the impact thermodynamics models on CO 2 storage capacity an aquifer, by using modelling and simulation transport phenomena in porous media. aquifer represented here a simplified three phase isothermal non-reacting medium composed inert solid two binary (CO H2O) fluid phases. mathematical description classically developed volume averaging method. For each phase...

The thermodynamics of the SU(3) gauge theory has been analyzed with tree level and tadpole improved Symanzik actions. A comparison with the continuum extrapolated results for the standard Wilson action shows that improved actions lead to a drastic reduction of finite cutoff effects already on lattices with temporal extent Nτ = 4. Results for the pressure, the critical temperature, surface tensi...
