Nanocomposite membrane comprising of both organic and inorganic material qualities have become a prime focus for the next generation membranes. Nanocomposite may consist of hard permeable or impermeable inorganic particles, such as zeolites, carbon molecular sieves and, silica and carbon nanotubes, metal oxide blended with continuous polymeric matrix presents an attract...

in this study, the effects of particle size distribution improvement and dense packing techniques on the 28- and 90-day compressive strengths of class g oil well cement have been investigated. it was observed that limited improvements in the particle size distribution of cement (regarding industrial possibilities) cannot result in a significant increase in 28- and 90-day compressive strengths. ...

Fluorine-containing polymers have a number of valuable physical and chemical properties, such as high chemical and heat resistance, high mechanical strength and highly selective gas separation characteristics. One of the ways to produce fluoropolymer membranes is through surface fluorination. The modifcation of commercial polymers with membrane properties, poly(4-methyl-1...

The great demand of beverages, both alcohol-free and with low alcohol content, is a great challenge for the production of beverages with controlled alcohol content through the use of sustainable enological practices. The present work addresses this challenge with the processing of grape must by reverse osmosis (RO) for must reconstitution with different sugar contents pr...

In this work, an efficient and facile method has been developed for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones from a condensation reaction of 2-aminobenzamide with various alkyl,aryl and alicyclic aldehydes or ketones using Fe3O<span class="fontstyle0" styl...

One of the goals of all pharmacological interventions aimed to increase the survival rateof patients with alcohol-dependent oropharyngeal cancers is to decrease alcohol use. Oxytocinis an alternative therapy for craving and alcohol management. However, the effectiveness ofoxytocin on the severity of alcohol dependence has not been evaluated. In an ABAB...

Knowing the overall solute flux and the partial fluxes expressed by every single transport layer, the membrane internal interface concentrations can separately be expressed. Both the overall transport coefcient and the driving force strongly depend, among others, on the value of the structural parameter and the water permeability. Study of the interface concentrations as ...
