Strong infrared photoluminescence from black silicon made with femtosecond laser irradiation.

Optics letters

Lü Q, Wang J, Liang C, Zhao L, Jiang Z.
PMID: 23595456
Opt Lett. 2013 Apr 15;38(8):1274-6. doi: 10.1364/OL.38.001274.

Strong infrared photoluminescence (PL) was observed for the first time from black Si (b-Si) formed by femtosecond laser irradiation and treated by rapid thermal annealing. The PL peak energy changes from 0.78 to 0.84 eV (1.59 to 1.48 μm)...

BACKGROUND: Local anesthetics (LAs) are generally considered as safe, but cytotoxicity has been reported for several local anesthetics used in humans, which is not well investigated. In the present study, the cytotoxicity of lidocaine, ropivacaine and the combination of...

Access to dihydropyridinones and spirooxindoles: application of N-heterocyclic carbene-catalyzed [3+3] annulation of enals and oxindole-derived enals with 2-aminoacrylates.

Chemical communications (Cambridge, England)

Chem Commun (Camb). 2017 May 30;53(44):5985-5988. doi: 10.1039/c7cc02753b.

A strategy for the NHC-catalyzed synthesis of dihydropyridinones and spirooxindoles has been developed via [3+3] annulation reactions of enals or isatin-derived enals with 2-aminoacrylates under oxidative conditions. In this efficient strategy, the 2-aminoacrylates served as nucleophiles. Modifying the standard...

BACKGROUND: Late course accelerated hyperfractionation radiotherapy (LCAHR) is used as a standard treatment option for locally advanced esophageal squamous cell carcinoma (LAESCC) in China, but concerns remain regarding its efficacy and safety. The purpose of this paper was to...

Generation mechanisms of fundamental rogue wave spatial-temporal structure.

Physical review. E

Ling L, Zhao LC, Yang ZY, Guo B.
PMID: 28950590
Phys Rev E. 2017 Aug;96(2):022211. doi: 10.1103/PhysRevE.96.022211. Epub 2017 Aug 22.

We discuss the generation mechanism of fundamental rogue wave structures in N-component coupled systems, based on analytical solutions of the nonlinear Schrödinger equation and modulational instability analysis. Our analysis discloses that the pattern of a fundamental rogue wave is...
