Nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. Hydroxyapatite (Ca10 (PO4)6(OH)2, HA) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. Firs...
MVP is a framework allowing websites to use diverse knowledgebased authentication schemes. One application is its use in conducting ecologically valid user studies of authentication under the same experimental conditions. We introduce MVP and its key characteristics, discuss several authentication schemes, and offer lessons learned from running 9 hybrid (lab/online) and 3 MTurk user studies ove...
Amit Desai, Maria L. Auad, 1 Hongbin Shen and Steven R. Nutt* Gill Foundation Composites Center, Department of Chemical Engineering and Materials Science, University of Southern California, 3651 Watt Way VHE-602, Los Angeles, CA 90089-0241, USA * E-mail: [email protected] Abstract: Hybrid composite phenolic foams are reinforced with chopped glass and aramid fibers in varied proportions. The mechanic...
Metallic foams with pore sizes from 250 lm to 2 mm have been a subject of research for over two decades due to their high surface area, which allows for a variety of applications, such as thermal and sound insulation. Recently, processing of metallic foams at the nanoscale (pores sizes less than 100 nm) has opened the door to new and interesting applications, such as sensors and actuators. In g...
The time-independent and time-dependent mechanical behavior of electrochemically lithiated silicon was studied with nanoindentation. As indentation was performed with continuous stiffness measurements during loading and load-hold, new insight into the deformation behavior of lithiated silicon is furnished. Supporting other research, Young's modulus and the hardness of lithiated silicon are foun...
Rice Husk Ash (RHA) of three different particle size ranges (50 – 75 μm), (75 – 100μm) and (100 – 150μm) in 3, 6, 9 and 12 % by weight was reinforced with the aluminium alloy using stir cast route. The microstructure and mechanical properties of the fabricated composites were analyzed. The results reveal that the tensile strength, compressive strength and hardness of the aluminum alloy composit...
Ahatraet-Using a binocular search coil technique, we measured oculomotor behavior during gentle pressing with a finger on the outer canthus of one eye. With a steadily pressed viewing eye, and the fellow eye occluded, the occluded eye deviates while the pressed eye does not. If the eye is rapidly pressed and released, the compensation of rotational force in the pressed eye becomes incomplete, s...
