Adsorption of a Nonionic Symmetric Triblock Copolymer on Surfaces with Different Hydrophobicity

Wu, Dong (AMER CHEMICAL SOC, 2010)

This study investigates the adsorption of a symmetric triblock nonionic polymer comprising ethylene oxide (EO) and propylene oxide (PO) blocks (Pluronic P-105, EO37PO56EO37) on a range of substrates including hydrophobic, ...
Concurrent Aggregation and Deposition of TiO2 Nanoparticles in a Sandy Porous Media

Wiesner, Mark (AMER CHEMICAL SOC, 2010)

The possibility of simultaneous particle aggregation and deposition in a porous medium was examined for the case of TiO2 nanoparticles (NPs). While potential for particle aggregation is typically assumed to be negligible ...
Distributions of Parameters and Features of Multiple Bond Ruptures in Force Spectroscopy by Atomic Force Microscopy

Guo, Senli; Li, Nan; Lad, Nimit; Desai, Shivam; Akhremitchev, Boris B. (AMER CHEMICAL SOC, 2010)

Force spectroscopy measurement of rupture forces of bound molecules becomes an important physicochemical tool in characterizing intermolecular interactions, Atomic force microscopy (AFM) measurements are among the most ...
Mechanical Distortion of Protein Receptor Decreases the Lifetime of a Receptor-Ligand Bond

Guo, Senli; Li, Nan; Lad, Nimit; Ray, Chad; Akhremitchev, Boris B. (AMER CHEMICAL SOC, 2010)

Substantial experimental evidence indicates that the mechanical force applied to pull apart non-covalent molecular bonds (such as receptor ligand pairs) can significantly decrease the bond lifetime. This evidence is often ...
Viscous State Effect on the Activity of Fe Nanocatalysts

Curtarolo, Stefano (AMER CHEMICAL SOC, 2010)

Many applications of nanotubes and nanowires require controlled bottom up engineering of these nanostructures In catalytic chemical vapor deposition, the thermo kinetic state of the nanocatalysts near the melting point is ...
