[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. Figure
   
   
 [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.
