Water reclamation is becoming a growing need, in particular developing countries where harvesting the required energy can be challenging problem. In this context, exploiting solar specifically tailored membrane distillation (MD) process viable solution. Traditional MD guarantees complete retention of non-volatile compounds and does not require high feed water temperatures. work, suitable amount...

The application of organic-inorganic nanocomposite membranes allows for a synergy between the desirable thermal and mechanical properties inorganic materials with reactivity, dielectric properties, durability, flexibility, processability polymeric materials. Proton exchange membrane fuel cells (PEMFCs) suffer from some problems including water content management, carbon monoxide poisoning, hydr...

A novel proton exchange membrane using phosphotungstic acid (HPW) as proton carrier and cubic bicontinuous Ia3d mesoporous silica (meso-silica) as framework material is successfully developed as proton exchange membranes for fuel cells. Meso-silica is functionalized by 80wt% HPW using a vacuum impregnation method. The HPW-functionalized meso-silica (HPW-meso-silica) nanocomposites are character...

Barrier membranes are used in periodontal applications with the aim of supporting periodontal regeneration by physically blocking migration of epithelial cells. The present work proposes a combination of chitosan (CHT) with bioactive glass nanoparticles (BG-NPs) in order to produce a novel guided tissue and bone regeneration membrane, fabricated by solvent casting. The CHT/BG-NP nanocomposite m...

Polyamide 6 (PA6) was melt-blended with an intumescent flame retardant (FR), multi-wall carbon nanotubes (MWNTs), and nanoclay particles to produce multi-component FR-PA6 nanocomposites. FR-PA6 nanofibers were processed from varied nanocomposite formulations via electrospinning. Electrospinnability, morphology, along with combustion and thermal properties of the nanofibers were investigated. Bo...

Clean water obtained by desalinating sea water or by purifying wastewater, constitutes a major technological objective in the so-called water century. In this work, a high-performance reverse osmosis (RO) composite thin membrane using multi-walled carbon nanotubes (MWCNT) and aromatic polyamide (PA), was successfully prepared by interfacial polymerization. The effect of MWCNT on the chlorine re...

Electrospinning is a simple and cost-effective approach for the production of nanofibers and assemblies with controllable structures. In this work, based on sol–gel chemistry and the electrospinning technique, porphyrin-doped nanocomposite fibers with a form of nanofibrous membrane were successfully fabricated without the addition or help of polymers, and were demonstrated as novel fluorescence...

Hypercrosslinked polymer (HCP) additives were successfully incorporated into two matrices: glassy with intrinsic microporosity comprising ethanoanthracene and Tröger's base (PIM-EA-TB) as well rubbery polydimethylsiloxane (PDMS), forming thin-film nanocomposite (TFN) membranes for organic solvent nanofiltration (OSN) applications. The thermal stability surface morphology of TFN characterized by...

New nanocomposite membranes with high bioactivity were fabricated using the electrospinning. These nanocomposites combine a degradable polymer poly(L/DL)-lactide and bone cell signaling carbonate nano-hydroxyapatite (n-HAp). Chemical and physical characterization of the membranes using scanning electron microscopy, Fourier transform infrared spectroscopy and the wide angle X-ray diffraction evi...
