recent publication

[09/28/2018] In collaboration with researchers from Cornell and NTU, we reported our observation of phase transitions in formamidinium lead iodide (FAPbI₃) under pressure. The article was just accepted by J. Am. Chem. Soc. FAPbI₃ is a hybrid compound, consisting of a perovskite alpha-phase and hexagonal (non-perovskite) delta-phase. Study on the pressure-induced structural evolution of this organic-inorganic compound is a hot topic. For the first time, the authors determined that the pressure could accelerate the alpha- to delta-FAPbI₃ transformation. link

[03/31/2016] A recent publication, "Pressure Dependent Polymorphism and Bandgap Tuning of Methylammonium Lead Iodide Perovskite", was chosen as a Hot article and has been featured in the online collection of "Nanoscale".

[02/02/2014] TOC of our recent publication, "Solvent-Mediated Self-Assembly of Nanocube Superlattices", has been selected as one of the "rolling pictures" on J. Am. Chem. Soc. homepage web site.

[12/10/2011] TOC of our recent publication, "Reversal of Hall-Petch Effect in Structural Stability of PbTe Nanocrystals and Associated Variation of Phase Transformation", has been selected and posted as one of "rolling pictures" on Nano. Lett. web site. http://pubs.acs.org/journal/nalefd

[5/01/2011] Our review paper, "self-Assembly of Lead Chalcogenide Nanocrystals" (Chem. Asian J. 6(5)/2011, page 1126), was recently published, and its art-work was chosen as a cover picture.

		[8/16/2010] Our new paper,
		"Enhancing by Weakening: Electrooxidation of Methanol on Pt₃Co and Pt Nanocubes" was just published in Angew. Chem. Int. Ed. In this work, Pt₃Co and Pt nanocubes were comparatively prepared and studied. The enhanced catalytic activity on Pt₃Co nanocubes was explained by the slower and weaker adsorption of CO onto the surface of Pt₃Co.

[12/1/2009] For the first time, we found that W(CO)₆ can control the morphology of Pt-3d-transition alloy nanoparticles and we have developed a general approach for preparation {100}-terminated Pt₃M nanocubes (M = Pt or Co, Fe, and Ni). This result was published in JACS.

[04/30/2009] Shape-controlled catalysis: High-quality Pt-Cu nanocubes with an average size of about 8 nm were synthesized from a high-temperature organic solution system in the presence of various capping ligands. These cubic Pt-Cu nanocrystals terminated with {100} facets demonstrated a superior catalytic activity towards methanol oxidation compared to similar sized Pt-Cu and Pt nanospheres. This result was published in Angew. Chem. Int. Ed. on 4/29/2009. This publication was highlighted as "VIP" (Very Important Paper).

[03/5/2009] We just received an invitation from Chem. Eur. J. that our accepted manuscript, Soluble InP and GaP Nanowires: Self-Seeded, Solution-Liquid-Solid Synthesis and Electrical Properties, has been highlighted with a frontispiece in a forthcoming issue.

[02/20/2009] We have controlled growth parameters and self-assembled various PbSe QD arrays on flat gold surface for scanning tunneling spectroscopy measurements. The current-voltage curves of the arrays were analyzed using double-barrier tunnel junction model to acquire the shunt capacitance between the array and the gold substrate. This article will be published in J. Phys. Chem. C on 5/7/2009, and the Cover Art will show up on issue 18, 2009.

[09/22/2008] Jun's research article, "Simple Cubic Super Crystals Containing PbTe Nanocubes and Their Core-Shell Building Blocks", was published in JACS.

[09/09/2008] Jun's research communication, entitled "p-Type Field-Effect Transistors of Single-Crystal ZnTe Nanobelts", was published in Angewandte Chemie Int. Ed.

[03/19/2008] Our self-assembly paper, entitled "Super-Crystal Structures of Octahedral c-In2O3 Nanocrystals", was published in JACS. In this article, we described and analyzed 2D and some 3D assemblies of uniform cubic-phase In₂O₃ NCs with octohedral shapes. We demonstrate our amazing observations on this kind of super crystals (or superlattices) as a model system, exposing largeness at least in tens of microns scale and other unique features.

[2/13/2008] Zhaoping's III-V QD paper was published in Angewandte Chemie and highlighted as VIP (Very Important Paper) on Feb. 13, 2007. Angewandte Chemie, weekly published by Wiley-VCH in Germany, is a leading Chemistry Journal with the highest Impact Factor (10.232 for 2006) in the field of Chemistry. Only a few percent of publications in this journal, which receive high evaluation from ALL of the reviewers, could be designated as a VIP.
