Paclitaxel Conjugate Block Copolymer Nanoparticle Formation by Flash NanoPrecipitation

Saad W.S., Mayer L., Princeton University, US

Nanoparticle formulations of drugs, printing inks, sun screens, and other hydrophobic organic compounds have distinct advantages in bioavailability, color intensity, and aesthetics. Common requirements of these applications are control of particle size and surface functionality. [...]

Electrohydrodynamic Patterning of Thin Polymer Film

Wu N., Pease III L.F., Russel W.B., Princeton University, US

A polymer melt sandwiched with a gap fluid between two planner electrodes can self assemble into ordered microstructures under the influence of an electric field. Motivated by the variety of patterns observed in experiments, we [...]

Preparation of Aggregation Stable Block Copolymer Nanoparticles for Simultaneous Drug Delivery and Imaging

Gindy M.E., Prud’homme R.K., Princeton University, US

We have developed a nanoparticle formation process based on rapid micromixing to produce high supersaturations, which we term Flash NanoPreciptiation.4, 5 This work introduces a novel approach that expands the applications of the Flash NanoPrecipitation [...]

Europium-Doped Yttrium Silicate Nanophosphors Prepared by Flame Synthesis

Qin X., Ju Y., Bernhard S., Yao N., Princeton University, US

Europium doped yttrium silicate nanophosphors were successfully synthesized for the first time by using the flame spray pyrolysis method at different silicon and europium concentrations. The effect of silicon concentration on the crystal structure, morphology, [...]

Nanotube in a periodic potential: A conveyer belt for electrons

Novikov D.S., Princeton University, US

We consider a carbon nanotube in the presence of an externally appliedperiodic potential. We show that, as a function of gate voltage that controls electron density (counted from the half-filled pi-band), the electron states can [...]

Synthesis of Y2O3:Eu Phosphor Nanoparticles by Flame Spray Pyrolysis

Qin X., Ju Y., Bernhard S., Yao N., Princeton University, US

Nanoscale Y2O3:Eu phosphor particles were synthesized by flame spray pyrolysis method and the effects of precursor solution and annealing treatment were discussed. The flame spray pyrolysis system consists of a spray generator, a coflow burner, [...]

Process Simulation for Contact Print Microlithography

Darhuber A.A., Miller S.M., Troian S.M., Wagner S., Princeton University, US

Using a combination of experiment and simulations, we have studied the conformation of liquid microstructures on both at and corrugated, chemically heterogeneous substrates. The artificial surface patterns, which define regions of different surface energy, induce [...]
