This paper describes a synthesis of free-standing, 10−15-nm-thick polymer films of well-defined lateral size and shape. The three key elements of this procedure are (1) formation by microcontact printing (μCP) of a patterned, self-assembled monolayer (SAM) with hydrophobic regions (alkane-terminated) and adsorption-re…

The one-step electrostatic complexation, reduction of aqueous chloroaurate ions and capping of the gold nanoparticles thus formed by hexadecylaniline Langmuir monolayers, is described. This process leads to the formation of highly oriented gold nanoribbons strongly bound to the Langmuir monolayer (images alongside) th…

New lanthanide complexes of 3-hydroxypicolinic acid (HpicOH) were prepared: [Ln(H 2 O)(picOH) 2 (μ-HpicO)]·3H 2 O (Ln = Eu, Tb, Er). The complexes were characterized using photoluminescence, infrared, Raman, and 1 H NMR spectroscopy, and elemental analysis. The crystal structure of [Eu(H 2 O)(picOH) 2 (μ-HpicO)]·3H 2…

In this paper, we study the changes in the structural, vibrational, bonding, and electronic properties of small clusters of the group III nitrides when an electron is added to the neutral clusters. The results, based on density functional calculations, reveal that the addition of an electron induces significant struct…

Important progress has been made in recent years toward developing a molecular-level understanding of protein phase behavior in terms of the osmotic second virial coefficient, a thermodynamic parameter that characterizes pairwise protein interactions. Yet there has been little practical application of this knowledge t…
