Bio-implantable passive on-chip RF-MEMS strain sensing resonators for orthopaedic applications
(Institute of Physics Publishing Ltd., 2008)One out of ten bone fractures does not heal properly due to improper load distribution and strain profiles during the healing process. To provide implantable tools for the assessment of bone fractures, we have designed ... -
Comparative study of optically activated nanocomposites with photocatalytic TiO2 and ZnO nanoparticles for massive environmental decontamination
(S P I E - International Society for Optical Engineering, 2007)Nanocomposites that incorporate TiO2 and ZnO nanoparticles separately in three-dimensional solgel matrices through full chemical integration are prepared to perform highly efficient photocatalytic activities for applications ... -
Design and realization of a fully on-chip High-Q resonator at 15 GHz on silicon
(Institute of Electrical and Electronics Engineers, 2008-12)We develop and demonstrate an on-chip resonator working at 15 GHz with a high quality factor (Q-factor) of 93.81 while only requiring a small chip size of 195 mu m x 195 mu m on Si by using our new design methodology. In ... -
Flexible metamaterials for wireless strain sensing
(American Institute of Physics, 2009-11-04)We proposed and demonstrated flexible metamaterial-based wireless strain sensors that include arrays of split ring resonators (SRRs) to telemetrically measure strain. For these metamaterial sensors, we showed that a flexible ... -
Metamaterial-based wireless strain sensors
(American Institute of Physics, 2009-07-07)We proposed and demonstrated metamaterial-based strain sensors that are highly sensitive to mechanical deformation. Their resonance frequency shift is correlated with the surface strain of our test material and the strain ... -
Near-unity efficiency energy transfer from colloidal semiconductor quantum wells of CdSe/cdS nanoplatelets to a monolayer of MoS2
(American Chemical Society, 2018)A hybrid structure of the quasi-2D colloidal semiconductor quantum wells assembled with a single layer of 2D transition metal dichalcogenides offers the possibility of highly strong dipole-to-dipole coupling, which may ... -
Nested metamaterials for wireless strain sensing
(IEEE, 2009-12-28)We designed, fabricated, and characterized metamaterial-based RF-microelectromechanical system (RF-MEMS) strain sensors that incorporate multiple split ring resonators (SRRs) in a compact nested architecture to measure ... -
Photocatalytic hybrid nanocomposites of metal oxide nanoparticles enhanced towards the visible spectral range
(Elsevier, 2011-04-13)We propose and demonstrate photocatalytic hybrid nanocomposites that co-integrate TiO(2) and ZnO nanoparticles in the same host resin to substantially enhance their combined photocatalytic activity in the near-UV and visible ... -
RF-MEMS load sensors with enhanced Q-factor and sensitivity in a suspended architecture
(Elsevier, 2010-11-09)In this paper, we present and demonstrate RF-MEMS load sensors designed and fabricated in a suspended architecture that increases their quality-factor (Q-factor), accompanied with an increased resonance frequency shift ... -
White emitting CdS quantum dot nanoluminophores hybridized on near-ultraviolet LEDs for high-quality white light generation and tuning
(Institute of Physics Publishing Ltd., 2008)To generate white light using semiconductor nanocrystal (NC) quantum dots integrated on light emitting diodes (LEDs), multiple hybrid device parameters (emission wavelengths of the NCs and the excitation platform, order ...
