Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...

A copper/low-density polyethylene nanocomposite (nano-Cu/LDPE), a potential intrauterine device component material, has been developed from our research. A logical extension of our previous work, this study was conducted to investigate the expression of plasminogen activator inhibitor 1 (PAI-1), substance P (SP), and substance P receptor (SP-R) in the endometrium of Sprague Dawley rats, New Zea...

polymer-clay nano-composite materials, in which nano-meter thick layers of clay dispersed in polymer matrix, have generally higher mechanical properties than normal polymeric materials. a new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. the total elastic modulus of nano-composite is evaluated.  numerical r...

Functionalized nanoporous materials have been developed recently as bio/chemical sensing materials. Due to the huge specific surface of the nano-materials for molecular adsorption, high hopes have been placed on gravimetric detection with micro/nano resonant cantilevers for ultra-sensitive sensing of low-concentration bio/chemical substances. In order to enhance selectivity of the gravimetric r...

Pervaporation membrane technology plays an important role in production of renewable bio-fuels. To improve the separation performance of polymeric membranes, an effective approach is development of mixed-matrix membranes containing high-performing fillers such as metal-organic frameworks. Towards practical application, hollow fiber could be an ideal substrate for mixed-matrix composite membrane...

increased number of adult patients requesting orthodontic treatment result in bonding bracket to ceramic restorations more than before. the aim of this study was to evaluate and compare the shear bond strength of orthodontic brackets bonded to two types of ceramic bases with conventional orthodontic bonding resin and a new nano-filled composite resin.twenty four feldespathic porcelain and 24 li...

The broad application of electrospun nanofibrous scaffolds in tissue engineering is limited by their small pore size, which has a negative influence on cell migration. This disadvantage could be significantly improved through the combination of nano- and microfibrous structure. To accomplish this, different nano/microfibrous scaffolds were produced by hybrid electrospinning, combining solution ...

Cobalt doped Zinc Oxide/Carbon nano composite was synthesized by solution combustion method and characterized by X-ray diffractometer, field emission scanning electron microscope and energy dispersive X-ray spectroscopy analysis. This composite shows X-ray diffraction pattern that matched with nano particle of ZnO with wurtzite structure and average grain size was found to be 10.53 nm. . Furthe...

In this study, the comparative role of nano‐ and micro‐sized Cu powder in exploring the influence on the tribo‐performance of friction materials in the form of brake‐pads is discussed. Two friction composites were developed by keeping allthe ingredients constant and varying the size of the selected filler (copper powder). The developed micro‐composite contained 10 % ...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...
