Use of corrugated steels in construction applications [PDF]

open access: yes, 2008
The Research Group of Materials Performance works in the study of several corrugated steels, especially stainless steels. Different aspects are developed as corrosion tests and evaluation of welded joints, between similar and dissimilar materials.

Surfing the Color Map with Carbazole‐Appended Cyclometalated N‐Heterocyclic Carbene Pt Complexes and Their Application in Green Organic Light‐Emitting Devices

open access: yesAdvanced Optical Materials, EarlyView.
Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.

Lineability and modes of convergence [PDF]

open access: yes, 2020
In this paper we look for the existence of large linear and algebraic structures of sequences of measurable functions with different modes of convergence. Concretely, the algebraic size of the family of sequences that are convergent in measure but not a.

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

Efficient Synthesis of Amino Lactones via Copper‐catalysed Alkene Aminooxygenation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract The synthesis of 5–7 membered oxygenated heterocycles by intramolecular aminooxygenation of unsaturated alkenes using commercially available N‐fluorobenzenesulfonimide as amination reagent and TpiPr2Cu(NCCH3) as precatalyst is reported. With unsaturated aliphatic carboxylic acids, the corresponding lactones are obtained from moderate to almost
