Nanodispersed DO(3)-phase nanostructures observed in magnetostrictive Fe-19% Ga Galfenol alloys
(American Physical Society, 2008-03-10)
Few nanometer large (<2 nm) inclusions of DO(3)-phase structure have been identified in the A2 matrix of highly magnetostrictive Fe-19% Ga alloys by high-resolution transmission electron microscopy (HRTEM). In addition, ...
Waste not want not: life cycle implications of gold recovery and recycling from nanowaste
(Royal Society of Chemistry, 2016-08-24)
Commercial-scale applications of nanotechnology are rapidly increasing. Enhanced production of nanomaterials and nano-enabled products and their resultant disposal lead to concomitant increases in the volume of nanomaterial ...
Nanoparticles in road dust from impervious urban surfaces: distribution, identification, and environmental implications
(Royal Society of Chemistry, 2016-05-24)
Nanoparticles (NPs) resulting from urban road dust resuspension are an understudied class of pollutants in urban environments with strong potential for health hazards. The objective of this study was to investigate the ...
Frequency-dependent stability of parallel-plate electrostatic actuators in conductive fluids
(AIP Publishing, 2010-05)
We present an electromechanical stability analysis of passivated parallel-plate electrostatic actuators in conductive dielectric media and show that the pull-in instability can be eliminated by tuning the applied frequency ...
High-performance carbon nanotube coatings for high-power laser radiometry
(American Institute of Physics, 2008-01-01)
Radiometry for the next generation of high-efficiency, high-power industrial lasers requires thermal management at optical power levels exceeding 10 kW. Laser damage and thermal transport present fundamental challenges for ...
Role of coexisting tetragonal regions in the rhombohedral phase of Na0.5Bi0.5TiO3-xat.%BaTiO3 crystals on enhanced piezoelectric properties on approaching the morphotropic phase boundary
(AIP Publishing, 2012-01-01)
The ferroelectric domain and local structures of Na0.5Bi0.5TiO3-xat.%BaTiO3 (NBT-x%BT) crystals for x = 0, 4.5, and 5.5 have been investigated by transmission electron microscopy. The results show that the size of polar ...
