The freezing behavior of gold nanoclusters was studied by employing molecular dynamics simulations based on the semiempirical embedded-atom method. Investigations of the gold nanoclusters revealed that, just after freezing, ordered nanosurfaces with a fivefold symmetry were formed with interior atoms remaining in the disordered state. Further lowering of temperatures induced nanocrystallization...

the thermal denaturation of adenosine deaminase (ada) has been investigated in the presence of sodium n-dodecyl sulphate (sds) over the temperature range of (293-363k) in 2.5 mm phosphate buffer, ph 6.4 by temperature scanning spectroscopy. the interaction of sds caused the folding of adenosine deaminanse resulting in a decrease of th (temperature of minimum solubility), ts (temperature of maxi...

the police are competent and always present contact persons who have direct knowledge and experience and act as role models in the area of road traffic. one of the focuses of police work is to increase tolerance and consideration, especially for more vulnerable road users. the priorities of the police are geared at emphasizing how relevant and appropriate the decisions made by road traffic auth...

For all M,N∈P(U) such that M⊂N, we first introduced the definitions of (M,N)-uni-soft ideals and (M,N)-uni-soft interior ideals of an ordered semigroup and studied them. When M=∅ and N=U, we meet the ordinary soft ones. Then we proved that in regular and in intra-regular ordered semigroups the concept of (M,N)-uni-soft ideals and the (M,N)-uni-soft interior ideals coincide. Finally, we introduc...

Cationic surfactantshaving long (C22)mono-unsaturated tailswerestudied inaqueoussolutionscontaining salt using steady and dynamic rheology. The surfactant erucyl bis(hydroxyethyl)methylammonium chloride self-assembles into giant wormlike micelles, giving rise to unusually strong viscoelasticity. Under ambient conditions, the viscosity enhancement due to surfactant exceeds a factor of 107. Some ...
