Tunable Hydrophobicity via Dimensionally Confined Polymerization of Organometallic Adducts

Recruiting physisorbed water in surface polymerization for bio-inspired materials of tunable hydrophobicity

Three-dimensionally Confined Diluted Magnetic Semiconductor Clusters

We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters o f 2 5 A diameter are successfully synthesized inside a glass matrix and fully characterized by chemical analysis, x-ray diffraction, extended x-ray absorption fine structure (EXAFS), and photoluminescence spectroscopy. Effect of size quantization on t...

Reply to "comment on 'insight into organometallic intermediate and its evolution to covalent bonding in surface-confined Ullmann polymerization'".

’ Song comments on our recent paper, stating “it is apparent that the conclusion drawn from the XPS measurements and analysis is questionable, and the discussion of the XPS section was not well addressed”. In this reply, we show that while some of Song's comments are pertinent to certain technical aspects of photoelectron spectroscopy, most of his assumptions are unjustified and the critique as...

On-surface Ullmann polymerization via intermediate organometallic networks on Ag(111).

The role of organometallic intermediates during on-surface polymerization via Ullmann coupling was studied on Ag(111). The polymerization progress was monitored by X-ray photoelectron spectroscopy (XPS). Scanning Tunneling Microscopy (STM) was used to characterize organometallic and covalent networks and to identify the temperature regimes for organometallic and covalent bond formation.

Fabrication of Corona-Free Nanoparticles with Tunable Hydrophobicity

A protein corona is formed at the surface of nanoparticles in the presence of biological fluids, masking the surface properties of the particle and complicating the relationship between chemical functionality and biological effects. We present here a series of zwitterionic NPs of variable hydrophobicity that do not adsorb proteins at moderate levels of serum protein and do not form hard coronas...
