Journal ArticleDOI
Observation of gigawatt-class THz pulses from a compact laser-driven particle accelerator.
A. Gopal,A. Gopal,S. Herzer,S. Herzer,Albrecht Schmidt,Pushkar Singh,A. Reinhard,Wolfgang Ziegler,D. Brömmel,A. Karmakar,Paul Gibbon,U. Dillner,T. May,H.-G. Meyer,Gerhard G. Paulus,Gerhard G. Paulus +15 more
TL;DR: Subpicosecond terahertz pulses with energies ≥460 μJ from a laser-driven ion accelerator are observed, thus rendering the peak power of the source higher even than that of state-of-the-art synchrotrons.
Journal ArticleDOI
Single molecule level plasmonic catalysis – a dilution study of p-nitrothiophenol on gold dimers.
TL;DR: Experimental evidence indicates that plasmon-induced hot electrons provide the required activation energy for surface plasmons to initiate intermolecular reactions of adsorbed p-nitrothiophenol.
Journal ArticleDOI
Characterization of 700 μJ T rays generated during high-power laser solid interaction
A. Gopal,Pushkar Singh,S. Herzer,A. Reinhard,Albrecht Schmidt,U. Dillner,T. May,H.-G. Meyer,Wolfgang Ziegler,Gerhard G. Paulus +9 more
TL;DR: The measurement of record-breaking T-Ray pulses with energies no less than 0.7 mJ are reported, revealing that the T rays are generated by the transient field at the rear surface of the solid target.
Journal ArticleDOI
Spatially resolved spectroscopic differentiation of hydrophilic and hydrophobic domains on individual insulin amyloid fibrils.
Tanja Deckert-Gaudig,Dmitry Kurouski,Martin A.B. Hedegaard,Pushkar Singh,Igor K. Lednev,Volker Deckert,Volker Deckert +6 more
TL;DR: The reproducibility of TERS is demonstrated, indicating its relevance for detecting molecular variations, and the ability of TERs to localize specific structural domains on fibril surfaces shows promise to the development of new fibrils dissection strategies.
Journal ArticleDOI
Surface-enhanced Raman scattering characteristics of CuO : Mn/Ag heterojunction probed by methyl orange: effect of Mn2+ doping
Om Prakash,Shiv Kumar,Pushkar Singh,Volker Deckert,Volker Deckert,Sandip Chatterjee,Ajoy Kanti Ghosh,Ranjan K. Singh +7 more
TL;DR: In this paper, a hybrid substrate for surface-enhanced Raman scattering (SERS) has been synthesized, where the nanostructured Ag island film and CuO nanoparticles are synthesized by vacuum thermal evaporation method and sol-gel method respectively, and a heterojunction between the CuO and Ag is fabricated by adsorption of CuO.
