Longitudinal leaky (LL) waves on YZ-LiNbO3 substrates [1, 2] feature many properties which are unusual for SAW and remain unexplained. Recent demonstration [3] of wideband low-loss filters operating on LL waves in the 2.5–5 GHz frequency range, manufactured with optical lithography, makes these waves of primary practical importance. Filters based on LL waves may become competitors against the F...
متن کاملTemperature Dependent 5f-states in URu2Si2
A dramatic temperature dependent enhancement of U 5f spectral weight at EF is observed in angle-resolved photoemission measurements of URu2Si2 at the center of an X-point hole-pocket. Comparison of this temperature dependent behavior for excitation both at and below the U 5d→5f resonant threshold is presented.
متن کاملMicroencapsulation in Food Chemistry
Encapsulation, invented in 1953 by B.K. Green & L. Schleicher employed in the laboratories of the National Cash Register Company, Dayton, USA, is defned as a technology of packaging solids, liquids, or gaseous materials in miniature, sealed capsules that can release their contents at controlled rates under specifc conditions. Encapsulation involves the incorporation of ...
متن کاملFrom macromolecules to electrons—grand challenges in theoretical and computational chemistry
Among the many achievements of the twentieth century the accelerating development of microprocessors and their capabilities is one of the most impressive accomplishments, influencing virtually every aspect of daily life. The impact of this new technological resource was (and still is) of particular importance for theoretical approaches in science and engineering. Although many theories (Schrödi...
متن کاملUltrafast Surface-Enhanced Raman Probing of the Role of Hot Electrons in Plasmon-Driven Chemistry.
Hot electrons generated through plasmonic excitations in metal nanostructures show great promise for efficiently driving chemical reactions with light. However, the lifetime, yield, and mechanism of action of plasmon-generated hot electrons involved in a given photocatalytic process are not well understood. Here, we develop ultrafast surface-enhanced Raman scattering (SERS) as a direct probe of...
