In this review, we present a comparison of the high-pressure phase behaviour of binary systems constituted of CO2 and ionic liquids of the [Cn(m)mim][Tf2N] type. The comparative study shows that the solubility of CO2 in ionic liquids of the [Cnmim][Tf2N] type generally increases with increasing pressure and decreasing temperature, but some peculiarities have been observed. The solubility of CO2...
The collisional system Si1He has been studied over a range of mean relative ion kinetic energy going from 10 to 10 eV/amu. In the low-energy range, a time-dependent wave-packet approach is used both in the diabatic and the adiabatic representation using two different propagator techniques. The agreement between the two sets of results assess the accuracy of the present numerical approach. Above...

We consider a class of optimal control problems of stochastic delay differential equations (SDDE) that arise in connection with optimal advertising under uncertainty for the introduction of a new product to the market, generalizing classical work of Nerlove and Arrow [30]. In particular, we deal with controlled SDDE where the delay enters both the state and the control. Following ideas of Vinte...
Emerging IC applications such as wireless sensor nodes, RFIDs, and medical devices place increasing emphasis on low energy operation instead of performance. Subthreshold circuits operate with a power supply set below the transistor voltage threshold and thus offer significant power reduction, while operating at frequencies in the range of a few MHz. A number of designs have successfully been pr...
Improving efficiency of hydrogen cooling in cryogenic conditions is important for the wider applications energy systems. The approach investigated this study based on a Ranque-Hilsch vortex tube (RHVT) that generates temperature separation working fluid. simplicity RHVT also valuable characteristic In present work, novel shapes are computationally with goal to raise process. Specifically, smoot...
A rate-based non-equilibrium model is developed for CO2 absorption with the mixture of piperazine and potassium carbonate solution. The based on mass heat transfer between liquid gas phases each packed column segment. thermodynamic equilibrium assumption (physical equilibrium) considered only at gas–liquid interface chemical assumed in phase bulk. calculated coefficient from available correlati...
solubility of high molecular weight n-paraffins in supercritical carbon dioxide has been a matter of interest to many researchers. however, not sufficient solubility experimental data are available although the methods by which the experimental data are obtained have many varieties. utilizing cubic equations of state is an effective method for solubility prediction of n-paraffins in supercritic...
