In the treatments of diffusion-limited association of suspended nanoparticles, their diffusion coefficients are usually considered to be constant and equal to those given by conventional hydrodynamics for diffusion of single nanoparticles. In reality, according to hydrodynamics, these coefficients depend, however, on the distance between nanoparticles. I show how this dependence can influence t...

We have used a simple ionic potential to simulate the melting of KCI pseudo-infinite crystal. Two MD simulations, one with constant Volume and the other with constant pressure condition are performed. These results are compared with the previous micro-sample simulation results. In the constant volume simulation the melting temperature increase substantially with increasing pressure. A method fo...

We study the capabilities of probabilistic finite-state machines that act as verifiers for certificates language membership input strings, in regime where are restricted to toss some fixed nonzero number coins regardless size. Say and Yakary?lmaz showed class languages could be verified by these within an error bound strictly less than 12 is precisely NL, but their construction yields with boun...

in this research some mathematical calculations has been explained on the “ +vo2 +glycylglycine” system and some equations has been deduced to determine the stability constants ofthe equilibrium models including mlh+, ml and ml2h species (while m+ ≡ +2 vo , h2l+ ≡protonated glycylglycine and mlh+, ml and ml2h represent the considered complexes). thecalculations are based on some relations betwe...

using the evaporating method, the solubility of potassium nitrate was determined in various mixtures containing water and ethanol at 25°c. the results show that the solubility of kno3 decreases with increasing the mass percent of ethanol in the mixtures. this trend is along with decreasing the dielectric constant of water+ethanol mixtures. moreover, it can be concluded that the totqal solubilit...
