Ripening of two-dimensional colloidal CdSe nanocrystals into zero-dimensional nanodots

Martinus Gijs, Virendra Kumar Parashar, Xiaopeng Huang

Understanding the ripening of two-dimensional (2D) colloidal nanocrystals (NCs) is important for the controllable synthesis of NCs with desired morphology and properties. In this study, we systematically investigate the ripening behavior of the 2D CdSe NCs ...

Nucleation and Growth Behavior of CdSe Nanocrystals Synthesized in the Presence of Oleylamine Coordinating Ligand

Martinus Gijs, Virendra Kumar Parashar, Xiaopeng Huang

We established the dual role played by oleylamine (OAm) during the synthesis of CdSe nanocrystals (NCs) by the hot injection method. Earlier reports suggest its role either as nucleating or as passivating agent in controlling the growth of CdSe NCs. Remark ...

C. Elegans Immobilization Using Deformable Microfluidics For In Vivo Studies Of Early Embryogenesis And Intestinal Microbiota

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong, Xiaopeng Huang, Jingwei Zhang

The genome of the nematode Caenorhabditis elegans shows far-reaching similarities to that of humans. C. elegans is therefore considered as a powerful model organism in biological research related to humans, for instance for the study of human diseases. Suc ...

Conductive framework of inverse opal structure for sulfur cathode in lithium-sulfur batteries

Hua Wu, Xiaopeng Huang, Lu Jin

As a promising cathode inheritor for lithium-ion batteries, the sulfur cathode exhibits very high theoretical volumetric capacity and energy density. In its practical applications, one has to solve the insulating properties of sulfur and the shuttle effect ...

Analysis of the dynamic response of pump-turbine runners- Part I: Experiment

François Avellan, Mohamed Farhat, Xiaopeng Huang, Eduard Egusquiza

When in operation, pump-turbine runners have to withstand large pressure pulsations generated by the rotor-stator interaction. The analysis of the dynamic behavior of these structures is necessary to avoid damage. For this analysis a realistic model of the ...
