Weighted norm inequalities for oscillatory integrals with finite type phases on the line
No full textAbstractWe obtain two-weighted L2 norm inequalities for oscillatory integral operators of convolution type on the line whose phases are of finite type. The conditions imposed on the weights involve geometrically-defined maximal functions, and the inequalities are best-possible in the sense that they imply the full Lp(R)→Lq(R) mapping properties of the oscillatory integrals. Our results build on work of Carbery, Soria, Vargas and the first author
Harnessing Plasticity in an Amine-Borane as a Piezoelectric and Pyroelectric Flexible Film
No full textWe demonstrate that trimethylamine borane can exhibit desirable piezoelectric and pyroelectric properties. The material was shown to be able operate as a flexible film for both thermal sensing, thermal energy conversion and mechanical sensing with high open circuit voltages (>10 V). A piezoelectric coefficient of d33≈10–16 pC N−1, and pyroelectric coefficient of p≈25.8 μC m−2 K−1 were achieved after poling, with high pyroelectric figure of merits for sensing and harvesting, along with a relative permittivity of (Formula presented.) 6.3.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Aerospace Structures & Material
Ireland-Claisen rearrangement of substrates bearing chiral enol ether units
No full textThe Ireland-Claisen [3,3]-sigmatropic rearrangement of an allylic glycinate bearing a remote chiral enol ether has been studied. Remote exopericyclic stereocontrol is achievable in this instance. The product from this rearrangement has been progressed through a formal total synthesis of the natural antibiotic, furanomycin
