This study aims to examine the properties of composites that different carbon materials with different measurements can reinforce. Using a melt compounding method, this study combines polypropylene (PP) and graphene nano-sheets (GNs) or carbon fiber (CF) to make PP/GNs and PP/CF conductive composites, respectively. The DSC results and optical microscopic observation show that both GNs and CF en...

BACKGROUND Postoperative complications of myringotomy and tube placement often include otorrhea, tympanosclerosis, and tympanic membrane perforation. However, the incidence of sensorineural or conductive hearing loss has not been documented. Recent efforts to curb the use of preoperative audiometric testing requires documentation of this incidence. OBJECTIVE To define the incidence of conduct...

Recently, dielectric elastomer actuators (DEAs) have gathered interest for soft robotics due to their low cost, light weight, large strain, low power consumption, and high energy density. However, developing reliable, compliant electrodes for DEAs remains an ongoing challenge due to issues with fabrication, uniformity of the conductive layer, and mechanical stiffening of the actuators caused by...

We synthesized new electroluminescence materials [(1,10-phenanthroline)(8-hydroxyquinoline)] Zn(phen)q and investigated their electron transport properties. We used Zn(phen)q and Alq3 for the conductive materials and measured their electron transport properties as a function of the organic layer thickness. The difference between Zn(phen)q and Alq3 as electron transporting materials suggests tha...

UNLABELLED In newborn hearing screening little importance is attributed to changes in the middle ear. Children with secretory otitis in the neonatal period are at risk for developing otitis media in the first year of life. AIM To determine if children who failed the hearing screening because of conductive hearing loss have more episodes of conductive hearing impairment during their first year...

Electrochemical micromachining (ECMM) is a non-conventional manufacturing method suitable for the production of microsized components on a wide range of conductive materials. ECMM improves dimensional accuracy and simplifies tool design for machining hard, high strength, heat resistant, and conductive materials into complex shapes. Extremely small interelectrode gaps of the order of few microns...

Curved, bendable, rollable, foldable, conformable, and stretchable displays have fascinated people in recent years. However, to commercialize these novel display devices and systems, not only fundamental developments on materials are required but also advancements on manufacturing techniques are necessary....

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. Induction heating is a process which is used to bond, harden or soften metals or other conductive materials. For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency and control. The induction he...

Conductive polymer composites require a three-dimensional 3D network to impart electrical conductivity. A general method that is applicable to most polymers for achieving a desirable graphene 3D network is still a challenge. We have developed a facile technique to fabricate highly electrical conductive composite using vacuum-assisted infusion of epoxy into graphene sponge GS scaffold. Macroscop...
