In their 2012 report, the President's Council of Advisors on Science and Technology advocated "replacing standard science laboratory courses with discovery-based research courses"-a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences...

Ligand displacement induced morphologies in block copolymer/quantum dot hybrids and formation of core-shell hybrid nanoobjects.

Phys Chem Chem Phys. 2017 Oct 18;19(40):27651-27663. doi: 10.1039/c7cp04343k.

We investigate the self-assembly of a cylinder-forming polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer (BCP) mixed with trioctylphosphine oxide (TOPO) capped cadmium selenide (CdSe) quantum dots (QDs). The QDs were found to be enthalpically compatible with the P4VP chains via ligand displacement...

[3]-Radialene-based dopant CN6-CP studied herein, with its reduction potential of +0.8 versus Fc/Fc+ and the lowest unoccupied molecular orbital level of -5.87 eV, is the strongest molecular p-dopant reported in the open literature, so far. The efficient p-doping of...

Map Edges: Focal Points for Facilitating Text Recall.

Contemporary educational psychology

Verdi MP, Stamm J, Johnson JT, Jamison M.
PMID: 11273657
Contemp Educ Psychol. 2001 Apr;26(2):211-226. doi: 10.1006/ceps.2000.1047.

In two experiments undergraduate students were shown maps with features located either along an edge or within the interior of the map. Next, participants were asked to read a related text. Thereafter, they were asked to recall as much...

Cascade of coil-globule conformational transitions of single flexible polyelectrolyte molecules in poor solvent.

Journal of the American Chemical Society

Kiriy A, Gorodyska G, Minko S, Jaeger W, Stepánek P, Stamm M.
PMID: 12418898
J Am Chem Soc. 2002 Nov 13;124(45):13454-62. doi: 10.1021/ja0261168.

We show that hydrophobic flexible polyelectrolyte molecules of poly(2-vinylpyridine) and poly(methacryloyloxyethyl dimethylbenzylammonium chloride) are trapped and frozen due to adsorption on the mica surface, and the observed AFM single molecule structures reflect the molecular conformation in solution. An increase...

Single flexible hydrophobic polyelectrolyte molecules adsorbed on solid substrate: transition between a stretched chain, necklace-like conformation and a globule.

Single flexible polyelectrolyte molecules of poly(2-vinylpyridine) undergo conformational transition from a stretched wormlike coil to a necklace-like globule, and to a compact globule depending on pH and ionic strength in aqueous solution in good agreement with recent theoretical reports....
