The Meijer transformation of generalized functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
This paper extends the Meijer transformation, Mμ, given by (Mμf)(p)=2pΓ(1+μ)∫0∞f(t)(pt)μ/2Kμ(2pt)dt, where f belongs to an appropriate function space, μ ϵ (−1,∞) and Kμ is the modified Bessel function of third kind of order μ, to certain generalized ...

Lead‐Free (K0.5Na0.5)NbO3 Unmodified Piezoceramics: A Reduction in the Energetic Budget of Solid State Synthesis and Sintering

open access: yesChemistry–Methods, EarlyView.
The temperature of the solid‐state synthesis of pure (K0.5Na0.5)NbO3 piezo‐composition is reduced by using the niobium pentoxide reactant in the mixture of reagents after attrition milling for only 3h: a majoritarian (57 wt.% of the total Nb2O5 content) orthorhombic polymorph Pbam.

Enhanced Piezoelectric Output and Electromechanical Response of ZnO Film Sensors via Orientation Induction and Rapid Deposition Strategies

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Employing an orientation induction and rapid deposition strategy, the oriented growth of ZnO piezoelectric films is effectively regulated, resulting in significantly enhanced piezoelectric polarization and electromechanical response. The ZnO OIL sensor exhibits excellent sensitivity, fast response, and high measurement accuracy in practical ...
