The purpose of this paper was to produce SiO₂ and TiO₂ nanowires via the electrospinning process from a polyvinylpyrrolidone (PVP)/Tetraethyl orthosilicate (TEOS)/Titanium (IV) butoxide (TNBT)/dimethylformamide (DMF) and ethanol (EtOH) solution. The as-obtained nanofibers were calcined at temperatures ranging from 400 °C to 600 °C in order to remove the organic phase. The one-dimensional cerami...

In bone tissue engineering, the organo-ceramic composite, electrospun polycaprolactone/hydroxyapatite (PCL/HA) scaffold has the potential to support cell proliferation, migration, differentiation, and homeostasis. Here, we report the effect of PCL/HA scaffold in tissue regeneration using human mesenchymal stem cells (hMSCs). We characterized the scaffold by fourier transform infrared spectrosco...

Recent advances in imaging technology have made it possible to capture three-dimensional (3D) images of pulp fibre based materials with high resolution (Antoine et al. 2002). This methodology can also be used for fibre-based composite materials. Analysis of such images can provide very detailed knowledge about the microstructure of the material, which in turn controls the mechanical properties....

  Solitary Fibrous Tumors (SFTs) are rare primary pleural neoplasms which have recently been reported in extra-thoracic sites. In this report, solitary fibrous tumor arising in an intra-thoracic goiter with no evidence of cervical mass in a 74-year-old obese man who was found to have a large superior mediastinal mass with tracheal deviation on Chest X-Ray is presented.

This study evaluates the impact of incorporating polypropylene fibers on endurance 100% ground granulated blast furnace slag (GGBFS) based alkali-activated composite (AAC) exposed to elevated temperatures. In addition, critical variants, like fiber volume fractions, length, alkaline solution monomer ratio, and curing regime, overall performance fibrous composites under high temperatures was eva...

Two polymer solutions of polyacrylonitrile, polyvinyl pyrrolidone, and Ni(CH3COOH)2 in dimethylformamide were electrospun into ternary composite nanofibers, followed by stabilization and carbonization processes to obtain porous carbon/nickel composite nanofibers with diameters of 100-200 nm. The study revealed that carbon/nickel composite nanofibers were successfully prepared, which allowed nic...

Although there is no doubt that composite materials are the future of lightweight structures and components, most composites currently produced made from thermoset polymers, which not able to be recycled or reprocessed. In contrast, thermoplastic polymers offer possibility recycle reprocess when combined with a fibrous reinforcement, provide interesting mechanical properties. This work reviews ...

In the present work, thermoplastic elastomeric nanofibers made up of a homogenous blend nitrile butadiene rubber (NBR) and Ppolycaprolactone (CL), with 80% wt rubbery component, are used to modify carbon fiber reinforced polymer (CFRP) laminate aim improving its delamination damping behavior at same time. Since nanofibrous membrane is not chemically cross-linked, fibrous morphology lost during ...

Over millennia nature has produced composite materials with excellent mechanical properties compared to the low of their base and managed obtain a good compatibility between stiffness toughness; as result, they are source inspiration for material optimization applications, such increasing toughness damage resistance, something that is difficult in conventional engineering materials. Nowadays ei...

The dispersion state and the efficiency of mixture different components in a composite film have an important impact on its mechanical optical properties. In present work, impacts treatments disaggregation fibrous clay particles water, properties related cellulose nanofiber (CNF)-based films, were evaluated. X-ray diffraction studies, performed samples sepiolite palygorskite, revealed only mino...
