The development of metal-organic frameworks (MOFs) for heavy metals removal from water faces ongoing challenge related to balancing performance with cost-effective synthesis. In this work, we report the first application Calgary Framework 20 (CALF-20), a zinc-based MOF synthesized via low-cost method, efficient adsorption Cu(II) and Pb(II) ions aqueous solutions. Synthesized at room temperature using commercially available, inexpensive reagents green solvents, CALF-20 represents highly...
Advanced materials including metal–organic frameworks (MOFs) are a critical piece of the puzzle in search for solutions to various scientific and technological challenges, such as climate change due ever-increasing emissions greenhouse gas. There is intense interest MOFs their potential use variety environmental applications, catalysis gas storage. In this work, we specifically focus on situ growth zeolitic imidazolate framework-67 (ZIF-67) poly(acrylonitrile) (PAN) fibers its application...
ABSTRACT Flexible conductive nanocomposites with the ability of self‐assembly into well‐ordered structures are promising multifunctional materials for energy conversion and storage devices. In this work, flexible based on multi‐walled carbon nanotubes (MWCNTs) poly(styrene‐butadiene‐styrene) (SBS) were obtained by solution casting, followed a post‐annealing treatment, during 7 days at 110 °C, to enable self‐organization SBS. The impact MWCNTs was studied atomic force microscopy Small angle...
Abstract Electrospun polystyrene (PS) fibers are produced using a mixed solvent of chloroform and n,n‐dimethylformamide (DMF) to investigate the influence ratio on fiber surface morphology contact angle obtained mats. Electrospinning is simple processing technique for producing with diameters in range nanometers few micrometers. When different ratios this process, porous PS membranes created due nonsolvent thermally induced phase separation (N‐TIPS). The analyzed through scanning electron...
Abstract KBiFe 2 O 5 (KBFO) is a perovskite‐like inorganic material that has great potential as an absorber for active layers of photovoltaic devices; however, the synthesis conditions reported until now (pressure and temperature) are inappropriate its direct deposition on usual substrates solar cells. Being able to synthesize these materials directly substrate avoids second stage this material, besides improving joining properties consequently energy conversion efficiency. To decrease...
Different concentrations of multiwall carbon nanotubes (MWCNT) and carboxyl functionalized MWCNT (MWCNT-COOH) were added to a high melt strength polypropylene (HMS-PP) produce foams with dielectric constants, using azodicarbonamide (AZO) as blowing agent. The AZO foaming behavior the crystallization, thermal properties, steady state oscillatory shear rheological properties nanocomposites analyzed by polarized light optical microscopy (PLOM), differential scanning calorimetry (DSC),...
Ferroelectric oxides are currently being studied as absorbing materials in photovoltaic devices due to their spontaneous polarization that facilitates charge separation. KBiFe2O5 (KBFO) is a ferroelectric oxide with perovskite like structure has low band gap; however, it relatively electrical conductivity, which makes difficult transport and collect carriers. One way of overcoming deficiency would be by decreasing the dimensions active layer. Thus, this work, for first time, nanofibers KBFO...

Abstract Linear low‐density polyethylene (LLDPE) is a polyolefin known for its superior low‐temperature heat seal ability, tolerance, and bag‐tear resistance which are important features the polymeric packaging sector. In this work, to improve mechanical properties expand range of applications LLDPE, microfibrillar clay mineral palygorskite (PAL) was added. However, use PAL as reinforcing agent polymers depends on purification process extract accessory minerals such calcite, dolomite,...
