Discriminated properties of PEI functionalized gold nanoparticles (Au-PEIs) predetermined by synthetic routes of ligand exchange and reduction processes: Paths and Fates

Cho T.J., Gorham J.M., Pettibone J.M., Hackley V.A., National Institute of Standards and Technology, US

Polyethyleneimine (PEI) functionalized AuNPs (Au-PEIs) have potential use as positively charged gold nanoparticles (AuNPs) for nano-medicinal applications, due to their cationic surfaces that promote cellular uptake and gene transfection.1-6 Au-PEIs can be prepared by one [...]

Positively charged Ag-dendron conjugates: Stability enhanced AgNPs for biomedical applications

Cho T.J., Liu J., Hackley V.A., National Institute of Standards and Technology, US

We developed positively charged silver nanoparticles ([Ag-Ds]+), nominally 20 nm in diameter, using dendron chemistry combined with reduction of silver nitrate in the presence of sodium borohydride. The conjugate was developed within the context of [...]

Nanoscale charge transport properties of perovskite solar cells with WSe2 flakes as protective layer for stable performance

Adhikari N., Bandyopadhyay A., Kaul A.B., The University of Texas, US

Organic-inorganic perovskite solar cells have become a promising technology for next generation solar cells due to their superior optoelectronic properties such as tunable low bandgap, long charge diffusion length, low exciton binding energy and balanced [...]

Use of Single Particle Inductively Coupled Plasma Mass Spectrometry to Characterize a New Silver Nanoparticle Reference Material

Murphy K.E., Liu J., Guthrie W.F., Gorham J.M., Bonevich J.E., Allen A.J., Winchester M.R., Hackley V.A., MacCuspie R.I., National Institute of Standards and Technology, US

In this study we use a conventional inductively coupled plasma mass spectrometer operated in single particle mode (spICP-MS) to simultaneously characterize the size distribution and dissolved silver fraction of a new candidate silver nanoparticle reference [...]

Behaviour of mesoporous silica (MCM-41) supported catalysts in degradation reactions

Guthrie C.P., Reardon E.J., University of Waterloo, CA

Research was carried out to investigate several aspects of Mobil’s composition of matter #41 (MCM-41) pertaining to its potential application in water treatment technologies. It was found that Pd-impregnated MCM-41 (Pd/MCM-41) has enhanced stability in [...]
