Research areas : Organic Electronics and Nano-fabrication-Our recent research theme is stretchable & patchable electronics based on polymeric substrates. Differ from other groups, we mainly deals with organic electronics by using UV-curable polymers as flexible substrates-We develop a novel fabrication technique for integrated organic devices on substrates with complex structure. Free-standing ...

BACKGROUND Many attempts have been performed and continued for improvement of dental amalgam properties during last decades. The aim of present research was fabrication and characterization of amalgam/titania nano composite and evaluation of its corrosion behavior. MATERIALS AND METHODS In this experimental research, nano particles of titania were added to initial amalgam alloy powder and the...

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...

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 ...

General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...

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...

A new route for the preparation of magneto-responsive polymeric gels involving iron nanoparticles as nano cross-linkers has been described.

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 % ...
