Experimental modulation bandwidth beyond the relaxation oscillation frequency in a monolithic twin-ridge laterally coupled diode laser based on lateral mode locking.

Optics letters

Lamela H, Roycroft B, Acedo P, Santos R, Carpintero G.
PMID: 18007784
Opt Lett. 2002 Mar 01;27(5):303-5. doi: 10.1364/ol.27.000303.

Monolithic twin-ridge laterally coupled diode lasers emitting at 1.3microm are presented that have a small-signal modulation bandwidth beyond the relaxation oscillation frequency of a single ridge. Spectra and spectrally resolved far fields are presented for three bias conditions: only...

Fluctuations of the Stokes and anti-Stokes surface-enhanced resonance Raman scattering intensities in an electrochemical environment.

Chemical communications (Cambridge, England)

dos Santos DP, Andrade GF, Brolo AG, Temperini ML.
PMID: 21611641
Chem Commun (Camb). 2011 Jul 07;47(25):7158-60. doi: 10.1039/c0cc05360k. Epub 2011 May 24.

Stokes and anti-Stokes SERRS intensity fluctuations were observed from a roughened silver electrode immersed in diluted solutions of Brilliant Green (BG), a behaviour linked to single-molecule events. The distributions of the anti-Stokes to Stokes ratios were obtained and their...

ChemistryOpen. 2013 Jun;2(3):106-14. doi: 10.1002/open.201300009. Epub 2013 May 06.

We have investigated the molecular geometries of a series of dicoordinated d(10)-transition-metal complexes ML2 (M=Co(-), Rh(-), Ir(-), Ni, Pd, Pt, Cu(+), Ag(+), Au(+); L=NH3, PH3, CO) using relativistic density functional theory (DFT) at ZORA-BLYP/TZ2P. Not all complexes have the...

Phase characterization of the reflection on an extreme UV multilayer: comparison between attosecond metrology and standing wave measurements.

Optics letters

Opt Lett. 2011 Sep 01;36(17):3386-8. doi: 10.1364/OL.36.003386.

We characterize the phase shift induced by reflection on a multilayer mirror in the extreme UV range (80-93 eV) using two techniques: one based on high order harmonic generation and attosecond metrology (reconstruction of attosecond beating by interference of...

The rumen is a complex ecosystem composed of anaerobic bacteria, protozoa, fungi, methanogenic archaea and phages. These microbes interact closely to breakdown plant material that cannot be digested by humans, whilst providing metabolic energy to the host and, in...

Indirect determination of formaldehyde by square-wave voltammetry based on the electrochemical oxidation of 3,5-diacetyl-1,4-dihydrolutidine using an unmodified glassy-carbon electrode.

Talanta

Talanta. 2019 Jun 01;198:237-241. doi: 10.1016/j.talanta.2019.01.108. Epub 2019 Feb 05.

A novel and indirect voltammetric procedure for the selective determination of formaldehyde is described. It is based on the oxidation of 3,5-diacetyl-1,4-dihydrolutidine (DDL) on an unmodified glassy-carbon electrode (GCE), generated by the selective reaction between formaldehyde and acetylacetone. A...

DNA-Based Assembly of Quantum Dots into Dimers and Helices.

Nanomaterials (Basel, Switzerland)

Nanomaterials (Basel). 2019 Mar 02;9(3). doi: 10.3390/nano9030339.

Owing to their unique optical properties, colloidal quantum dots (QDs) have attracted much attention as versatile fluorescent markers with broad biological and physical applications. On the other hand, DNA-based assembly has proven to be a powerful bottom-up approach to...
