Journal ArticleDOI
Direct evaluation of the sp3 content in diamond-like-carbon films by XPS
TL;DR: In this paper, the analysis of the X-ray photoelectron spectra (XPS) of the C 1s core level of pulsed laser deposited diamond-like carbon thin films, obtained at different laser intensities is presented.
Journal ArticleDOI
A photoinduced metal-like phase of monoclinic VO2 revealed by ultrafast electron diffraction
Vance R. Morrison,Robert P. Chatelain,Kunal L. Tiwari,Ali Hendaoui,Andrew Bruhacs,Mohamed Chaker,Bradley J. Siwick +6 more
TL;DR: By photoexciting the monoclinic semiconducting phase, the authors were able to induce a transition to a metastable state that retained the periodic lattice distortion characteristic of the semiconductor but also acquired metal-like mid-infrared optical properties.
Journal ArticleDOI
Harvesting Lost Photons: Plasmon and Upconversion Enhanced Broadband Photocatalytic Activity in Core@Shell Microspheres Based on Lanthanide-Doped NaYF4, TiO2, and Au
Zhenhe Xu,Marta Quintanilla,Fiorenzo Vetrone,Alexander O. Govorov,Mohamed Chaker,Dongling Ma +5 more
TL;DR: In this paper, a plasmonic Au nanoparticle decorated NaYF4:Yb3+, Er3+, Tm3+core@porous-TiO2-shell microspheres is reported.
Journal ArticleDOI
Temporal characterization of femtosecond laser pulses induced plasma for spectrochemical analysis of aluminum alloys
B. Le Drogoff,Joëlle Margot,Mohamed Chaker,Mohamad Sabsabi,O. Barthélemy,T. W. Johnston,S. Laville,F. Vidal,Y. von Kaenel +8 more
TL;DR: In this paper, a time-resolved space-integrated laser induced breakdown spectroscopy (LIBS) of plasmas produced by ultrashort laser pulses at atmospheric pressure, on aluminum alloy targets has been characterized.
Journal ArticleDOI
Gold nanoparticle decorated ceria nanotubes with significantly high catalytic activity for the reduction of nitrophenol and mechanism study
TL;DR: In this article, a new nanostructured catalyst, made of small uniform gold nanoparticles (AuNPs) and ceria nanotubes (CeO2NTs), is presented.
