Ideal Polyethylene Nanocrystals
Journal of the American Chemical Society, 2013The water-soluble catalyst precursor [[(2,4,6-(3,5-(CF3)2C6H3)3-C6H2)-N═C(H)-(3-(9-anthryl)-2-O-C6H3)-κ(2)-N,O]Ni(CH3)(TPPTS)] (TPPTS = tri(sodiumphenylsulfonate)phosphine) polymerizes ethylene to aqueous dispersions of highly ordered nanoscale crystals (crystallinity χ(DSC) ≥ 90%) of strictly linear polyethylene (

Manganese‐Doped Zirconia Nanocrystals
European Journal of Inorganic Chemistry, 2008AbstractIn recent theoretical work, it was predicted that transition‐metal‐doped zirconia (ZrO2) can be ferromagnetic at room temperature with a dependence on the metal dopant and its oxidation state and concentration. For experimental verification of these predictions, manganese‐doped ZrO2 nanoparticles were synthesized.

Colloidal synthesis of nanocrystals and nanocrystal superlattices
IBM Journal of Research and Development, 2001This paper provides an overview of the synthetic techniques used to prepare colloidal nanocrystals (NCs) of controlled composition, size, shape, and internal structure and the methods for manipulat...

Non-blinking Semiconductor Nanocrystals
Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009The photoluminescence from a variety of individual molecules and nanometre-sized crystallites is defined by large intensity fluctuations, known as 'blinking', whereby their photoluminescence turns 'on' and 'off' intermittently, even under continuous photoexcitation.

Single-Nanocrystal Spectroscopy of White-Light-Emitting CdSe Nanocrystals
The Journal of Physical Chemistry A, 2011We report the observation of broad-spectrum fluorescence from single CdSe nanocrystals. Individual semiconductor nanocrystals typically have a narrower emission spectrum than that of an ensemble. However, our experiments show that the ensemble white-light emission observed in ultrasmall CdSe nanocrystals is the result of many single CdSe nanocrystals ...

Nanocrystal Plasma Polymerization: From Colloidal Nanocrystals to Inorganic Architectures
Accounts of Chemical Research, 2008Nanocrystal superstructures are increasingly becoming a subject of intense study. Such materials could constitute a new class of nanocomposites of designed structure, of homogeneous composition, and with unique properties. New phenomena are observed in these materials because of the interaction at such diminutive length scales.

Multitwinned nanocrystals are commonly found in substances that preferentially adopt tetrahedral local arrangements, but not yet in water crystals. Ice nanocrystals are pivotal in cloud microphysics, and their surfaces become increasingly prominent in determining structure as crystal size decreases.
