Piezoelectric principles are widely used to harvest energy in the process of vibrating piezoelectric mass. Different design configurations were studied in the research papers listed. A novel dynamic method of Lead Zirconate Titanate Sensor (PZT) to obtain d33 suitable for the MEMS applications is designed, simulated and analysed results were compared with the fabricated sensor. The Lead Zircona...

Modulating the second-order nonlinear optical susceptibility (χ(2)) of materials at the nanoscale represents an ongoing technological challenge for a variety of integrated frequency conversion and nonlinear nanophotonic applications. Here we exploit the large hyperpolarizability of intermolecular charge transfer states, naturally aligned at an organic semiconductor donor-acceptor (DA) interface...

Peptides have attracted considerable attention due to their biocompatibility, functional molecular recognition and unique biological and electronic properties. The strong piezoelectricity in diphenylalanine peptide expands its technological potential as a smart material. However, its random and unswitchable polarization has been the roadblock to fulfilling its potential and hence the demonstrat...

ZrO2 and TiO2 modified lead-free (K0.5Na0.5)NbO3 (KNN) piezoelectric ceramics are prepared by conventional solid-state reaction. The effect of acceptor doping on structural and functional properties are investigated. A decrease in the Curie temperature and an increase in the dielectric constant values are observed when doping. More interestingly, an increase in the coercive field Ec and remanen...

We derive new temperature dependent Sellmeier equations for the extra-ordinary and ordinary refractive indices of 0.5% MgO-doped stoichiometric LiTaO3 crystal. The equations are based on quasi phase-matched frequency conversion measurements, as well as on interferometric measurements of the thermal expansion and thermal dispersion. These equations fit experimental data over wide spectral ranges...

The reaction mechanisms for K (1385) photoproduction from the reaction γp → K+ 0(1385) in the resonance energy region are investigated in a hadronic model. Both contributions from N and resonances of masses around 2 GeV as given in the Review of Particle Data Group and by the quark model predictions are included. The Lagrangians for describing the decays of these resonances into K (1385) are co...

Evolution of the Industrial Wage Structure in China Since 1980 Industry mean wages in China have exhibited sharply increased dispersion since the early 1990s. The upward trend in differences of average wages among major industry groups parallels increases in wage and income inequality not only between rural and urban sectors but within the urban economy as well. Research on the trend has focuse...

We report on a high-efficiency 461 nm blue light conversion from an external cavityenhanced second-harmonic generation of a 922 nm diode laser with a quasi-phasematched KTP crystal (PPKTP). By choosing a long crystal (LC = 20mm) and twice looser focusing (w0 = 43μm) than the ”optimal” one, thermal lensing effects due to the blue power absorption are minimized while still maintaining near-optima...

We have investigated the effect of texture on in-plane sIPPd and out-of plane sOPPd polarizations of pulsed-laser-deposited BaTiO3 thin films grown on Pt and La0.5Sr0.5CoO3 sLSCOd buffered Pt electrodes. The OPP and IPP polarizations were observed by piezoresponse force microscopy sPFMd for three-dimensional polarization analyses in conjunction with conventional diffraction methods using x-ray ...

Pb(In(12)Nb(12))O(3)-Pb(Mg(13)Nb(23))O(3)-PbTiO(3) (PIN-PMN-PT) single crystals have been developed recently, which can increase the operating temperature by at least 20 degrees C compared to PMN-PT crystals. We have measured a complete set of material properties of single domain PIN-PMN-PT crystal, which is urgently needed in theoretical studies and electromechanical device designs using this ...
