This work was aimed at researching and developing a computer model, as well an optimization control algorithm for calculating pore shapes separating membranes in separation processes. Two types of flow fluid rates through with various pores configurations were considered. Here, the first type had form tortuous channel sharp narrowing endings, which, turn, could be assumed “zero” wall thickness ...

in recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ils) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. sonic speed is an important thermodynamic property of ionic liquids (ils) and always chosen as a source to determine other properties. a database for the sonic speed of pure ils cre...

For two algebras $A$ and $B$, a linear map $T:A longrightarrow B$ is called separating, if $xcdot y=0$ implies $Txcdot Ty=0$ for all $x,yin A$. The general form and the automatic continuity of separating maps between various Banach algebras have been studied extensively. In this paper, we first extend the notion of separating map for module case and then we give a description of a linear se...

The present investigation entails a procedure by which the surface tension and viscosity of liquids could be redicted.To this end, capillary experiments were performed for porous media by utilizing fifteen different liquids and powders. The time of capillary rise to a certain known height of each liquid in a particular powder was recorded. Two artificial neural networks (ANNs) were...

a simple and mild method for tetrahydropyranylation of alcohols is reported at room temperature using a catalytic amount of 3-methylimidazolinium hydrogensulfate([hmim]hso4) as a green, efficient and reusable catalyst. using solvent-free conditions, non-toxic and inexpensive materials, modest and clean work-up, short reaction times and high yields of the products are the advantages of this method.

n-(diphenylphosphino)triethyl- and tributylammonium salts are introduced as easily prepared, cheap and stable ionic liquids that act as the condensing agent and media for the efficient esterification of acids with alcohols and phenols. this class of ionic liquids is immiscible with the ester products and thus allows simple and easy separation of the desired products from the reaction mixture.

Pyridinium based ionic liquids derived from β-picoline and n-alkylbromides were synthesized by a simple procedure at ambient temperature and then characterized. These neutral ionic liquids were investigated for their dual role as the solvent and promoter for the selective synthesis of a series of N-monomethylanilines using dimethylcarbonate as the methylating agent. A solvent free gree...

Abstract The shear–driven, bilayer flow of two immiscible liquids sandwiched between a moving planar and stationary corrugated plate, in parallel alignment under Stokes conditions, is explored. motivation, partly inspired by biomimetic considerations, the use surface texturing/topography to reduce friction wear while increasing load carrying capacity lubrication problems. starting point associa...

Using bosonization, we study a model of parallel quantum wires constructed from two-dimensional Dirac fermions in the presence periodic topological domain walls. The accounts for lateral spread wave functions $\ensuremath{\ell}$ transverse direction to wires. gapless modes confined each wall are shown form Luttinger liquids, which realize well-known smectic non-Fermi liquid fixed point when int...

Microwave spectroscopy method has become widespread in many applications including liquid classification. In this study, a microwave system that can classify liquids without opening the lid of their containers is proposed. Thus, operators are prevented from being exposed to harmful substances and wasting time. Everyday such as carbonated drinks, fruit juices, shampoo, cream alcoholic beverages ...
