6. Oceanapins A-F, unique branched ceramides isolated from the haplosclerid sponge Oceanapia cf. tenuis of the Coral sea

Author(s) : Mancini, I. , Guella, G. , Debitus, Cécile , Pietra, F.
Description : A series of ceramides, called oceanapins A-F (2-7), which are unique for branching at both the sphingosine and fatty-acid chains, have been isolated as pure compounds from the haplosclerid sponge #Oceanapia$ cf. #tenuis$ of the Coral Sea. Following acid hydrolysis, both the fatty-acid and the sphing...

On the novel free porphyrins corallistin B, C, D, and E : isolation from the demosponge Corallistes sp. of the Coral Sea and reactivity of their nickel (2) complexes toward formylating reagents

Author(s) : D'Ambrosio, M. , Guerriero, A. , Debitus, Cécile , Ribes, Olivier , Pietra, F.
Description : Reported here are the novel free corallistin B, C, D, and E, isolated as methyl esters 2a, 3a, 4a, and 5a, respectively, from the sponge #Corallistes$ sp.(#Lithistida$) collected at the basis of the South New Caledonian coral reef. A protocol is also established for formulation of their NiII complex...

Thermally induced atomic reconstruction of PbSe/CdSe core/shell quantum dots into PbSe/CdSe bi-hemisphere hetero-nanocrystals

Author(s) : Grodzinska, D. , Pietra, F. , Huis, M.A. van , Vanmaekelbergh, D.A.M. , Mello Donega, C. de
Description : The properties of hetero-nanocrystals (HNCs) depend strongly on the mutual arrangement of the nanoscale components. In this work we have investigated the structural and morphological evolution of colloidal PbSe/CdSe core/shell quantum dots upon annealing under vacuum. Prior to annealing the PbSe cor...

High-Temperature Luminescence Quenching of Colloidal Quantum Dots

Author(s) : Zhao, Y. , Riemersma, C. , Pietra, F. , Mello Donega, C. de , Meijerink, A.
Description : Thermal quenching of quantum dot (QD) luminescence is important for application in luminescent devices. Systematic studies of the quenching behavior above 300 K are, however, lacking. Here, high-temperature (300–500 K) luminescence studies are reported for highly efficient CdSe core–shell quantum do...
