Thermal conductivity of self-assembled nano-structured ZnO bulk ceramics
(American Institute of Physics, 2012-08-01)
In this study, we describe the changes in thermal conductivity behavior of ZnO-Al micro- and nano-two-phase self-assembled composites with varying grain sizes. The reduction in thermal conductivity values of micro-composites ...
Enhanced piezoelectric performance from carbon fluoropolymer nanocomposites
(American Institute of Physics, 2012-12-15)
The piezoelectric performance of polyvinylidene fluoride (PVDF) is shown to double through the controlled incorporation of carbon nanomaterial. Specifically, PVDF composites containing carbon fullerenes (C-60) and single-walled ...
Biomimetic and Live Medusae Reveal the Mechanistic Advantages of a Flexible Bell Margin
Flexible bell margins are characteristic components of rowing medusan morphologies and are expected to contribute towards their high propulsive efficiency. However, the mechanistic basis of thrust augmentation by flexible ...
Broadband/Wideband Magnetoelectric Response
A broadband/wideband magnetoelectric (ME) composite offers new opportunities for sensing wide ranges of both DC and AC magnetic fields. The broadband/wideband behavior is characterized by flat ME response over a given AC ...
Harvesting Energy from the Counterbalancing (Weaving) Movement in Bicycle Riding
Bicycles are known to be rich source of kinetic energy, some of which is available for harvesting during speedy and balanced maneuvers by the user. A conventional dynamo attached to the rim can generate a large amount of ...
Synthesis and Optical Characterization of Mg1-xNixO Nanostructures
An attempt has been made here to synthesize nano-powders via sol-gel process. These powders are shown to possess an f.c.c. (NaCl-type) structure with a typical lattice parameter of Å for when decomposition of dried ...
