We studied the equilibrium self-assembly of an equimolar mixture uniaxial liquid crystals (LCs) and magnetic nanoparticles (MNPs) using molecular dynamics simulations. The LCs are modeled by ellipsoids interacting via Gay–Berne potential, MNPs represented dipolar soft spheres (DSS). found that show isotropic, nematic, smectic phases when is compressed at a fixed temperature. DSS form chain-like...

A secondary battery (accumulator) employing molten metals or metal alloys as active masses at both electrodes and a salt electrolyte in between is called an all-liquid-metal accumulator (LMB). Separation of the liquid based on segregation caused by different densities immiscibility materials characteristic feature. High coulometric storage capabilities molten-metal combined with relatively low ...

We examined liquidus phase relations in Fe-O ± H at ∼40 and ∼150 GPa, Fe-H 45 GPa. While it has been speculated that Fe FeH form continuous solid solution to core pressures, our experiment on showed FeH0.20 forms with the hcp structure, different from fcc for stoichiometric FeH, melts temperature lower than suggesting eutectic melting between FeH. It is consistent diagram Fe-O-H, which implies ...

Background and objectives: Evaluating the safety of pharmaceutical products by in vitro methods like cell culture, and in vivo tests on animals, is one of the regulatory steps in development of drugs which is called the preclinical stage. If acceptable results are obtained, the drug can be used in clinical studies. In this study, we have investigated the cytot...

Bacteria growing on surfaces appear to be profoundly more resistant to control by lytic bacteriophages than do the same cells grown in liquid. Here, we use simulation models to investigate whether spatial structure per se can account for this increased cell density in the presence of phages. A measure is derived for comparing cell densities between growth in spatially structured environments ve...

We demonstrate for the first time a tight binding model for water incorporating polarizable oxygen atoms. A novel aspect is that we adopt a "ground up" approach in that properties of the monomer and dimer only are fitted. Subsequently we make predictions of the structure and properties of hexamer clusters, ice-XI and liquid water. A particular feature, missing in current tight binding and semie...

Phase-field simulations are used to examine tip velocity and shape selection in free dendritic growth of a pure substance into an undercooled melt in the presence of a density change between the solid and liquid. The dendrite is assumed to grow two-dimensionally inside a Hele-Shaw cell. The phase-field model is coupled with a previously developed two-phase diffuse interface model to simulate th...

We describe in detail a recently proposed lattice-Boltzmann model for simulating flows with multiple phases and components. In particular, the focus is on the modeling of one-component fluid systems which obey non-ideal gas equations of state and can undergo a liquid-gas type phase transition. The model is shown to be momentum-conserving. From the microscopic mechanical stability condition, the...

The first redox flow battery (RFB), based on the all-copper liquid metal salt [Cu(MeCN)4][Tf2N], is presented. Liquid metal salts (LMS) are a new type of ionic liquid that functions both as solvent and electrolyte. Non-aqueous electrolytes have advantages over water-based solutions, such as a larger electrochemical window and large thermal stability. The proof-of-concept is given that LMSs can ...
