We evaluated the histopathological response of the periodontal membrane to intentionally-replanted teeth carrying composite (experimental) and silver amalgam (control) restorations in the middle third of each root. The study revealed that the amalgam produced, in the periodontal tissues, an initial localized inflammation that subsided with the subsequent formation of a fibrous capsule. However,...

In bone tissue engineering, collagen/hydroxyapatite (HAP) fibrous composite obtained via electrospinning method has been demonstrated to support the cells' adhesion and bone regeneration. However, electrospinning of natural collagen often requires the use of cytotoxic organic solvents, and the HAP crystals were usually aggregated and randomly distributed within a fibrous matrix of collagen, lim...

The quality of fibrous reinforcements used in composite materials can be monitored during the weaving process. Fibrous sensors previously developed in our laboratory, based on PEDOT:PSS, have been adapted so as to directly measure the mechanical stress on fabrics under static or dynamic conditions. The objective of our research has been to develop new sensor yarns, with the ability to locally d...

Novel composite fibrous membranes loaded with mesalazine and metronidazole were fabricated via interlaced electrospinning. The fibers were characterized by scanning electron microscopy and FTIR transmission spectra techniques. These characterizations were performed in the aim of optimizing the experimental conditions which allowed us to obtain good morphology of fibrous membrane loaded drugs. T...

Creep can be dangerous for electromechanical, electronic and electrical connections, networks and devices. Recently, the metal matrix composites (MMC’s) are generally used for designing the electromechanical and electrical systems and devices due to their advantages. Therefore, analysis of the creep behavior is necessary and important for safe designing the fibrous composite devices. For achiev...

A facile method termed magneto-mechanical drawing is used to produce polymer composite microfibers. Compared with electrospinning and other fiber spinning methods, magneto-mechanical drawing uses magnetic force generated by a permanent magnet to draw droplets of polymer/magnetic nanoparticle suspensions, leading to fabrication of composite microfibers. In addition, because of the rotating colle...
