The synthesis and characterization of Pt core/ Cu shell (Pt@Cu) dendrimer-encapsulated nanoparticles (DENs) having full and partial Cu shells deposited via electrochemical underpotential deposition (UPD) is described. Pt ...

We report a new and general approach that will be useful for adapting the method of electrocatalytic amplification (ECA) to biosensing applications. In ECA, individual collisions of catalytic nanoparticles with a noncatalytic ...

This dissertation describes the synthesis and characterization of nitrogen doped carbon nanotube (NCNT) supported nanoparticles for catalysis, specifically, the cathodic oxygen reduction reaction (ORR) in fuel cells. ...

As computational methods for the prediction of metallic nanoparticle structure and reactivity continue to advance, a need has developed for simple experimental models that can mimic and confirm theoretical predictions. ...

Surface-enhanced Raman scattering (SERS) from organic molecules is used to study how geometry affects plasmonic enhancement in noble metal nanoparticles using super-resolution analysis techniques coupled with scanning ...

Herein, experiment and theory are combined to study the efficacy of synthesizing core@shell Au@Pt dendrimer-encapsulated nanoparticles (DENs) through electrochemical means. DENs are small (~1-2 nm), catalytically active ...

Direct-write multiphoton-excited photocrosslinking of chemically active threedimensional (3D) protein microstructures could potentially extend in situ cellular analysis to include more interactive studies of neural ...

Electrochemical band gaps from semiconductor nanoparticles (NPs) such as CdSe and CdTe showed a size-confinement effect, and the values were in good agreement with the optical band gaps. For example, differential ...

The science and technology of catalysis is more important today than at any other time in our history due to the grand energy and environment challenges we are facing. With the explosively growth of computation power ...

The creation of next-generation functional materials will require fine control of nanoscale surface characteristics. Two common approaches to this problem are the formation of nanoparticles and the synthesis of mesoporous ...
