Highly luminescent, manganese doped, zinc sulphide (ZnS:Mn) nanocrystals biofunctionalized with chitosan and various aminoacids such as L-citrulline, L-lysine, L-arginine, L-serine, L-histidine and glycine were synthesized by chemical capping co-precipitation method at room temperature, which is a simple and cost effective technique. The synthesized nanocrystals were structurally characterized ...

Cu particles with different architectures such as pyramid, cube, and multipod have been successfully fabricated on the surface of Au films, which is the polycrystalline Au substrate with (111) domains, using the electrodeposition technique in the presence of the surface-capping reagents of dodecylbenzene sulfonic acid and poly(vinylpyrrolidone). Further, the growth evolution of pyramidal Cu nan...

Biaxially oriented CaF2 films have been created by first using an oblique incidence vapor flux to deposit CaF2 onto an amorphous surface to form vertically aligned nanorods which served as seeds to grow a more continuous CaF2 capping layer under a subsequent normal incidence flux deposition. The entire film possesses a unique {111}/121S biaxial texture as shown by X-ray pole figure analysis and...

Submitted for the MAR15 Meeting of The American Physical Society Quantitative analysis of actin monomer funneling: how capping protein enhances actin filament growth and nucleation on biomimetic beads1 RUIZHE WANG, ANDERS CARLSSON, Washington University — Capping protein (CP) caps the growing ends of actin filaments and thereby halts their polymerization. However, CP is required for actin-based...

a r t i c l e i n f o Keywords: Iron pyrite FeS 2 nanocrystals Thin films Ligand exchange Surface stability Photovoltaic Iron pyrite (FeS 2) is a promising photovoltaic absorber material with a high natural abundance and low cost, but surface defects and low photoresponse inhibit sunlight energy conversion. The surface stability of pyrite FeS 2 nanocrystals synthesized in oleylamine (OLA) with ...

Objective(s): In this work, pomegranate juice was used as a capping agent for self- assembly to form particles-like Au nanostructures in the presence of AuHCl4.3H2O as aurate source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiments were...

We investigated how heterodimeric capping proteins bind to and dissociate from the barbed ends of actin filaments by observing single muscle actin filaments by total internal reflection fluorescence microscopy. The barbed end rate constants for mouse capping protein (CP) association of 2.6 x 10(6) M(-1) s(-1) and dissociation of 0.0003 s(-1) agree with published values measured in bulk assays. ...

In this research, we prepared composite films via covalent coupling of CdSe quantum dots (QDs) to graphene through the direct binding of aryl radicals to the graphene surface. To compare the carrier transport with the CdSe aryl binding graphene film, we prepared CdSe pyridine capping graphene films through the pi-pi interactions of noncovalent bonds between the graphene and pyridine molecules. ...

We investigate crystalline magnetic anisotropy in the electric field (EF) for the FePt surface which has a large perpendicular anisotropy, by means of the first-principles approach. Anisotropy is reduced linearly with respect to the inward EF, associated with the induced spin density around the Fe layer. Although the magnetic anisotropy energy (MAE) density reveals large variation around the at...
