Single photon emission up to liquid nitrogen temperature from charged excitons confined in GaAs-based epitaxial nanostructures

We demonstrate a non-classical photon emitter at near infrared wavelength based on a single (In, Ga)As/GaAs epitaxially grown columnar quantum dot. Charged exciton complexes have been identified in magneto-photoluminescence. Photon auto-correlation histogr ...

A Pyridine-Based Ligand with Two Hydrazine Functions for Lanthanide Chelation: Remarkable Kinetic Inertness for a Linear, Bishydrated Complex

Lothar Helm, Eva Jakab Toth

To study the influence of hydrazine functions in the ligand skeleton, we designed the heptadentate HYD ligand (2,2',2 '',2 ''-(2,2'-(pyridine-2,6-diyl)bis(2-methylhydrazine-2,1,1-triyl)) tetraacetic acid) and compared the thermodynamic, kinetic, and relaxa ...

Molecular Hydrogen Messengers Can Lead to Structural Infidelity: A Cautionary Tale of Protonated Glycine

Thomas Rizzo, Antoine Louis Claude Masson, Evan Rowland Williams

The effects of tagging protonated glycine with either He or with between 1 and 14 H2 molecules on the infrared photodissociation (IRPD) spectra and the ion structure was investigated. Differences in the IR spectra with either a single He atom or H2 molecul ...

Metal-Based Optical Probes for Live Cell Imaging of Nitroxyl (HNO)

Pablo Rivera Fuentes

A review. Nitroxyl (HNO) is a biol. signaling agent that displays distinctive reactivity compared to nitric oxide (NO). As a consequence, these two reactive nitrogen species trigger different physiol. responses. Selective detection of HNO over NO has been ...

Tetracarboxylatoplatinum(IV) complexes featuring monodentate leaving groups - A rational approach toward exploiting the platinum(IV) prodrug strategy

Hristo Plamenov Varbanov

A series of novel symmetrically and unsymmetrically coordinated platinum(IV) complexes with monodentate carboxylato ligands was synthesized. The compounds exhibit a general coordination sphere of [Pt(en)(OCOR)(2)(OCOR')(OCOR '')1, where the carboxylato lig ...

Observation of sea-salt fraction in sub-100nm diameter particles at Cape Grim

Robin Lewis Modini

Volatility-hygroscopicity tandem differential mobility analyzer measurements were used to infer the composition of sub-100nm diameter Southern Ocean marine aerosols at Cape Grim in November and December 2007. This study focuses on a short-lived high sea sp ...

Substitutional or Interstitial Site-Selective Nitrogen Doping in TiO2 Nanostructures

Raffaella Buonsanti, Anna Loiudice

Herein, we report a colloidal wet-chem. approach enabling control on dopant concn. and location in a nanocrystal host lattice. Growth-doping and nucleation-doping, driven by primary and tertiary amines, resp., were identified as predominant doping mechanis ...

Autotrophic and heterotrophic nutrient fluxes in the dinoflagellate-coral symbiosis – A NanoSIMS perspective

Anders Meibom, Isabelle Domart-Coulon, Thomas Krüger, Maoz Fine, Julia Marie Jeanne Yvonne Bodin

The exchange of metabolites between photosynthetic symbionts and their coral host in shallow-water scleractinians provides the nutritional basis for their successful evolution and the existence of massive coral reefs in oligotrophic tropical waters. Autotr ...
