of the human ear, a better understanding of biomechanics of the ear for sound transmission is achieved. The acoustic-mechanical vibration and energy transmission through the middle ear in normal and diseased ears can be visualized and quantified in a 3-dimensional FE model. Four novel model-derived “auditory test curves” named as the middle ear transfer function, energy absorbance, admittance tympanogram, and tympanic membrane holography are generated with clinically relevant applications.

Carbon micropatterns (CMs) were fabricated from a negative-type SU-8 photoresist by proton ion beam lithography and pyrolysis. Well-defined negative-type SU-8 micropatterns were formed by proton ion beam lithography at the optimized fluence of 1×1015 ions cm?2 and then pyrolyzed to form CMs. The crosslinked network structures formed by proton irradiation were converted to pseudo-graphitic structures by pyrolysis. The fabricated CMs showed a good electrical conductivity of 1.58×102 S cm?1 and a...

a coupling agent (Z6040) and with poly(amidoamine) (PAMAM) a dendrimer containing an ethylenediamine core and amine surface groups. The MWCNT were deposited on the CF using two methods, by electrostatic attraction and by chemical reactions. The changes in the CF surface morphology after the MWCNT deposition were analyzed using SEM, which revealed a higher density and uniform coverage for the PAMAM-treated CF and the short MWCNTs. The interfacial adhesion of the composite materials was evaluated...

We studied the basic properties and fabrication of reduced graphene oxide (rGO) prepared using eco-friendly reduction agents in the graphene solution process. Hydrazine is generally used to reduce graphene oxide (GO), which results in polluting emissions as well as fixed nitrogen functional groups on different defects in the graphene sheets. To replace hydrazine, we developed eco-friendly reduction agents with similar or better reducing properties, and selected of them for further analysis. In...

Dyes are widely used in various industries including textile, cosmetic, paper, plastics, rubber, and coating, and their discharge into waterways causes serious environmental and health problems. Four different carbon nanostructures, graphene oxide, oxidized multi-walled carbon nanotubes, activated carbon and multi-walled carbon nanotubes, were used as adsorbents for the removal of Nile Blue A (NBA) dye from aqueous solution. The four carbon nanostructures were characterized by scanning electron...

Polycrystalline diamond (PCD) tools possessing high hardness and abrasive wear resistance are particularly suited for drilling of carbon fiber reinforced plastic (CFRP) composites, where tool life and consistent hole quality are important. While PCD presents superior performance when drilling CFRP, it is unclear how it performs when drilling multi-stack materials such as CFRP-titanium (Ti) stacks. This comparative study aims to investigate drilling of a Ti plate stacked on a CFRP panel when...

The aim of the work was to investigate the thermo-electrical properties of low cost and rapidly produced randomly oriented carbon/carbon (C/C) composite. The composite body was fabricated by combining the high-pressure hot-pressing (HP) method with the lowpressure impregnation thermosetting carbonization (ITC) method. After the ITC method step selected samples were graphitized at 3000°C. Detailed characterization of the samples’ physical properties and thermal properties, including thermal...

or a semi-metal electronic structure, its ionization energy is 4 eV [1] and it has dual electronic characteristics. Thus, it may work as either an oxidizer or reducer. In particular, the shape of the graphite plays an important role in its mechanical characterization [2]. Graphene, in its role as a unit cell of graphite, is known to have great potential for applications in many fields [3]. It is critical to understand graphite’s interfacial interaction with a matrix, or its wettability, when...

the importance and applications of composite materials are gradually increasing [1]. In the field of metal-matrix composite manufacturing, reinforcing agents are added to the metal matrix in the form of powders, whiskers, and fibers to improve the mechanical properties of metals [2]. Fibers have been used since the 1950s as structural reinforcements to develop metal-matrix composites. However, the improvements in physical properties in terms of high strength under extreme conditions have not yet...
