Recently, it has been observed that the effective dipolar interactions between nuclear spins of spin-carrying molecules of a gas in a closed nano-cavities are independent of the spacing between all spins. We derive exact time-dependent polarization for all spins in spin1 2 ensemble with spatially independent effective dipolar interactions. If the initial polarization is on a single (first) spin...

Bubbles in asset prices have fascinated researchers in finance. Identify asset bubbles, by circumstances, on the stock market has been a growing number of research theoretical and empirical. On a theoretical level, it was assumed that the price dynamics reflect irrational behavior of economic agents and, therefore, should be excluded from a deal with the truly rational economic agents Burmeiste...

The Enskog-Vlasov equation has been proven successful in capturing the complex behaviour of fluids undergoing a phase change. However, its numerical solution is computationally demanding, and this restricted studies to one- two-dimensional planar flows. In work, weighted particle scheme developed for Enskog–Vlasov spherically symmetric geometry. It shown how schemes designed Boltzmann can be ex...

Hydrate-based technologies have excellent application potential in gas separation, storage, transportation, and seawater desalination, etc. However, the long induction time slow formation rate are critical factors affecting of hydrate-based technologies. Micro-nano bubbles (MNBs) can dramatically increase hydrates owing to their advantages providing more nucleation sites, enhancing mass transfe...

One of the main applications ultrasonic melt treatment is grain refinement aluminium alloys. Among several suggested mechanisms, fragmentation primary intermetallics by acoustic cavitation regarded as very efficient. However, physical process causing this has received little attention and not yet well understood. In study, we evaluate mechanical properties Al3Zr nano-indentation experiments cor...

Micro-nano bubbles (MNBs) are tiny bubbles with diameters on the order of micrometers and nanometers, showing great potential in environmental remediation. However, the application is only in the beginning stages and remains to be intensively studied. In order to explore the possible use of MNBs in groundwater contaminant removal, this study focuses on the transport of MNBs in porous media and ...
