Morphology-controlled nanomaterials such as silica play a crucial role in the development of technologies for addressing challenges in the fields of energy, environment, and health. After the discovery of Stöber silica, followed by that of mesoporous silica materials, such as MCM-41 and SBA-15, a significant surge in the design and synthesis of nanosilica with various sizes, shapes, morphologie...

In this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (CNTs) is proposed in detail. The negative coefficient of thermal expansion and the high young’s modulus of CNTs can be utilized to counterbalance the process induced residual stresses in composites. To this end, first, the effects of adding CNTs to the matrix of fibrous composi...

Composite materials by definition are a combination of two or more materials. Although the idea of combining two or more components to produce materials with controlled properties has been known and used from time immemorial, modern composites were developed only several decades ago and have found by now intensive application in different fields of engineering (Vasiliev&Morozov, 2001). These ma...

Egg capsules from two caenogastropod whelks, Busycon canaliculatum and Kelletia kelletii, were studied to investigate the genesis of mechanical properties of nascent capsules and to formulate a biomechanical model of this material. Scanning electron microscopy revealed that the capsules possess fibrous hierarchical arrangements at all stages during processing while the mechanical integrity is d...

External auditory canal (EAC) stenosis is commonly seen in patients with fibrous dysplasia of the temporal bone. Postoperative canal restenosis is more likely to be encountered after initial surgical management. We present a case of monostotic fibrous dysplasia of the temporal bone with EAC invasion in a 37-year-old man who presented with recurrent canal stenosis and resultant conductive hearin...

Electrospinning (e-spinning) is a versatile technique to fabricate ultrathin fibers from a rich variety of functional materials. In this paper, a modified e-spinning setup with two-frame collector is proposed for the fabrication of highly aligned arrays of polystyrene (PS) and polyvinylidene fluoride (PVDF) nanofibers, as well as PVDF/carbon nanotube (PVDF/CNT) composite fibers. Especially, it ...

The evaluation of composite anterior cruciate ligament prostheses, the union of an inductor of collagen and a synthetic fibre, are described. They were implanted in 10 sheep models for six months. None of the ligaments were broken, and the dynamic radiography was stable during this time. After harvesting them, a histologic study was performed on the intra-osseou and intra-articular portion, and...

A numerical model is presented to simulate the crystallization kinetics in fiber-based composite with thermoplastic semicrystalline matrix. The proposed model, based on Schneider's formalism, considers specificity of crystalline entities growing confined medium such as fibrous composite. Indeed, transcrystallization has been experimentally observed many times and its effects both mechanical pro...

Introduction Engineering textiles used in composite materials can be considered as porous materials because of the open spaces between the fibers in a bundle and between the woven bundles themselves. These spaces are commonly referred to as microscopic and mesoscopic pores. The dual scale porosity of fibrous reinforcements is of great importance when studying Liquid Composite Molding (LCM) proc...

Articular cartilage from a material science point of view is a soft network composite that plays a critical role in load-bearing joints during dynamic loading. Its composite structure, consisting of a collagen fiber network and a hydrated proteoglycan matrix, gives rise to the complex mechanical properties of the tissue including viscoelasticity and stress relaxation. Melt electrospinning writi...
