The in-plane dielectric and ferroelectric properties of preferentially oriented lead zirconate titanate (PZT) thin films are characterized using interdigitated transducers (IDTs). By combining finite element method simulations capacitance measurements, values the constant with thicknesses between 150 nm 800 obtained. A modified Sawyer–Tower circuit is used to investigate polarization loops meas...

This study explores Generation Z hotel employees’ perception of and behavioral intention to use advanced information technologies (ITs) before during COVID-19. The relationship between moderated by COVID-19 is investigated. technology acceptance model (TAM) innovation diffusion theory (IDT) are integrated, compatibility added as an additional construct conduct this longitudinal study. Data were...

Bulk heterojunction organic solar cells (BHJs) are competitive within the emerging photovoltaic technologies for energy conversion because of their unique advantages. Their development has been boosted recently by introduction nonfullerene electron acceptors (NFAs), to be used in combination with a polymeric donor active layer composition. Many recent advances NFAs attributable class fused-ring...

Cracking is a major distress in asphalt pavement which can lead to premature pavement failures and can cost agencies millions of dollars in maintenance and rehabilitation costs. Even with modern advances in pavement engineering, attempts to quantify and model cracking in asphalt pavements have proved extremely challenging; this is due to the visco-elastic behavior of asphalt concrete and the co...

The influence of backbone fluorination and sidechain regiochemistry on an indacendithiophene (IDT) core containing electron withdrawing N-cyanoimine groups is investigated.

This paper proposes a method to realize ideal lithium niobate (LiNbO3) A1 resonators. By introducing subwavelength through-holes between the interdigital transducer (IDT) electrodes on LiNbO3 surface, all unfavorable spurious modes of resonators can be suppressed completely. It is convenient and valid for various IDT electrode parameters different thicknesses. Also, this does not require additi...

The hypergolic reaction between the recently developed green propellant combination consisting of an ionic liquid and highly concentrated hydrogen peroxide was investigated for various fuel to oxidizer ratios heights fall. influence catalytic copper additive on ignition delay time (IDT) analyzed. Flame emission/absorption spectroscopy revealed chemical constituents. All emission spectra were do...

Abstract The modification of the nature and size bandgaps for III-V semiconductors is strong interest optoelectronic applications. Strain can be used to systematically tune bandgap over a wide range values induce indirect-to-direct transition (IDT), direct-to-indirect (DIT), other changes in nature. Here, we establish predictive first-principles approach, based on density functional theory, ana...
