Flaky FeSiAl alloy/multi-wall carbon nanotube (FeSiAl/MWCNT) composite was fabricated by facile and scalable ball milling method. The morphology and electromagnetic properties of the FeSiAl alloy can be well tuned by controlling the milling time. It is found that the magnetic loss of the FeSiAl alloy is improved by optimizing the milling time due to the increased anisotropy field. Meanwhile the...

wood is a naturally renewable material with both continuous and isolated pore systems. wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. however, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. using nano-materials are very easy in the wo...

Nanoparticles with sizes ranging between objects and microparticles (e.g. atom) have attracted much attention. These particles with various specialized functions not only deepen our understanding of nature, but also serve as the basis for the development of new advanced technology. The successful application of nanoparticles depends upon both the synthesis and the surface modification of these ...

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...

The purpose of this pilot investigation was to measure the co-efficient of friction of a cast cobaltchromium alloy specimen and three materials commonly found on the guiding surfaces of the teeth. The static .co-efficients of friction between dental cobalt-chromium alloy (before and after electropolishing) and tooth enamel, composite resin, and dental amalgam alloy were measured using an inclin...

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 ...
