Ag(Nb<sub>0.8</sub>Ta<sub>0.2</sub>)O<sub>3</sub> is used here as a model system to shed light on the nature of low temperature phase behavior unsubstituted parent compound AgNbO<sub>3</sub>, which an important material for high-power energy storage applications.
The (Nb + In) co-doped TiO2 ceramics recently attracted considerable attention due to their colossal dielectric permittivity (CP) (∼100,000) and low loss (∼0.05). In this research, the 0.5 mol. % In-only, Nb-only, 0.5–7 were synthesized by standard conventional solid-state reaction method. Microstructure studies showed that all samples in pure rutile phase. Nb ions homogeneously distributed grain boundary. Impedance spectroscopy I-V behavior analysis demonstrated may compose of...
Real-time characterization of microresonator dynamics is important for many applications. In particular, it critical near-field sensing and understanding light–matter interactions. Here, we report camera-facilitated imaging analysis standing wave patterns in optical ring resonators. The pattern generated through bidirectional pumping a microresonator, the scattered light from collected by short-wave infrared (SWIR) camera. recorded scattering are wavelength dependent, intensity exhibits...
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by severe decline of memory performance. A widely studied AD mouse model the APPswe/PSEN1ΔE9 (APP/PS1) strain, as mice exhibit amyloid plaques well impaired capacities. To test whether restoring synaptic plasticity and decreasing β-amyloid load Parkin could represent potential therapeutic target for AD, we crossed APP/PS1 transgenic with overexpressing ubiquitin ligase analyzed offspring properties....
Electrocaloric refrigeration utilizing ferroelectrics has recently gained tremendous attention because of the urgent demand for solid-state cooling devices. However, low room-temperature electrocaloric effect and narrow operation temperature window hinder implementation lead-free in high-efficiency applications. In this work, chemical engineering thick-film architecture design strategies were integrated into a BaTiO3-based system to resolve challenge. Novel environmental-friendly...
BaTiO 3 ( BTO ) nanofibers were fabricated by sol–gel combined with electrospinning method. The effects of the concentration acetic acid and sintering temperatures on crystal phase microstructure samples investigated scanning electron microscopy, X‐ray diffraction, transmission microscopy TEM ). improved surface morphology obtained as ethanol to ratio (E/A) was 8:3. fibers calcined at 750°C for 2 h exhibited good crystallization. studies revealed that polycrystalline, diameters being order...
A simple method was introduced to fabricated energy harvester, which shows flexibility, high efficiently and effective operation between room temperature Curie temperature.
In this study, we theoretically proposed a method to achieve an electromagnetically induced transparency (EIT)-like effect in whispering gallery mode resonator (WGMR) and experimentally validated the lithium niobate (LN) device. Benefitting from electro-optic inverse piezoelectric effects of LN material, two modes WGMR that are close frequency can be tuned at different tuning rates, resulting EIT-like resonance lineshapes. By varying electric field applied WGMR, full dynamic phenomenon...
This study focuses on an experimental investigation of asphaltene deposition in a vertical transparent microchannel. Heptane-induced precipitation is utilized to precipitate dissolved crude oil into particles at ambient temperature and standard atmospheric pressure. These deposit gradually the surface microchannels. The key parameters that influence mechanism are ratio n-heptane elapsed time. At constant flowrate, amount deposited channel wall quantified using new flow visualization...
The relaxor–PbTiO3 single crystal has attracted extensive attention in ultrasound transducers, sensors, actuators, and optoelectronics devices due to its excellent piezoelectric response electro–optic properties. Preparation of a single–domain as critical process for application non–linear optical suffers from serious inevitable cracking. Therefore, pre-poling thermal annealing was suggested release residual stress growth the ferroelectric–paraelectric phase transition, which significantly...
Transmission spectrum and refractive index of (1−x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN-xPT) single crystals were studied second-harmonic generation signal the crystal powder was measured in order to characterize nonlinear optical properties crystals.
