Texture is a phenomenon in image data that continues to receive wide-spread interest due to its broad range of applications. The paper focuses on but one of several ways to model textures, namely, the class of stochastic texture models. the authors introduce a new spatial stochastic model called partially ordered Markov models, or POMMs. They show how POMMs are a generalization of a class of mo...

Pervaporation and gas separation performances of polymer membranes can be improved by crosslinking or addition of metal-organic frameworks (MOFs). Crosslinked copolyimide membranes show higher plasticization resistance and no significant loss in selectivity compared to non-crosslinked membranes when exposed to mixtures of CO2/CH4 or toluene/cyclohexane. Covalently crosslinked membranes reveal b...

Anthropogenic emissions have developed the environmental demands for proficient carbon dioxide (CO2) separation technologies. Adsorption and membrane technologies are widely used to separate CO2 from other light gases due their multiple technological benefits, including but not limited factors such as energy efficiency low footprint. In this context, zeolites often intrinsic molecular sieving c...

Metall-organische Netzwerke (MOFs) und kovalente organische (COFs) wurden in den letzten Jahren intensiv auf Anwendungen als Gastrennmembranen untersucht. Seitdem modernste Präparationsverfahren für MOFs COFs Partikel, Dünnschichtmembranen Mixed-Matrix-Membranen (MMMs) entwickelt. Es werden neuartige Verfahren hochfunktionale Materialien vorgestellt: Zeolithische Imidazolat-Netzwerke (ZIFs) kön...

Purpose: To investigate the impact of neurogenic lower urinary tract dysfunction (NLUTD) and sexual (SD) on multiple sclerosis (MS) patients' quality life health perceptions evaluate possible relationship with disease parameters.
 Materials Methods: A total 192 patients MS were included in study. Along King's Health (KHQ) COOP/WONCA questionnaires, Arizona Sexual Experience Scale (ASEX), B...

The use of zeolites as fillers in mixed matrix membranes (MMM) gas separation is a well-studied subject. difficulties to produce membrane with high selectivity and low defects the zeolite/polymer interface are well documented. Many researchers have reported that functionalization zeolite surface led higher compatibility via using silane groups, amine or ionic liquids particles improve permeabil...

2D metal–organic frameworks are attractive filler in mixed matrix membranes (MMMs) due to the high aspect ratio and contact opportunity at filler–polymer interface. However, their alignment polymer remains a challenge fully play functions. Herein, our best knowledge, for first time, facile synthesis of KAUST-7-NH2 (KAUST, King University Science Technology) nanoplate is reported with 1D channel...

In this work, the effectiveness of metal-organic frameworks (MOFs) with sheet-like morphologies was assessed as function MOF microporosity and MOF-matrix compatibility. Zeolitic imidazolate (ZIFs, a subclass) sheet-like/platelet were incorporated in Matrimid/PBI matrices resulting mixed matrix membranes (MMMs). The ZIFs either permeable (ZIF-301) or impermeable (ZIF-95X) for gases kinetic diame...
