Preparation, Characterization, and Biological Activity of Stability-Enhanced Polyethyleneimine-Conjugated Gold Nanoparticles (Au-PEI@NIST) for Biological Application

September 16, 2021
Tae Joon Cho, Vincent A. Hackley, Feng Yi, David A. LaVan, Vytas Reipa, Alessandro Tona, Bryant C. Nelson, Christopher Sims, Natalia Farkas
In this special publication, we report on a modified synthetic process that results in a stable suspension of Au-PEI nanoparticles, Au-PEI@NIST. Synthesized materials were characterized using an orthogonal approach that included dynamic light scattering

An Inter-Laboratory Comparative High Throughput Experimental Materials Study of Zn-Sn-Ti-O Thin Films

March 19, 2019
Jason R. Hattrick-Simpers, Zachary T. Trautt, Kamal Choudhary, Aaron G. Kusne, Feng Yi, Martin L. Green, Sara Barron, Andriy Zakutayev, Nam Nguyen, Caleb Phillips, John Perkins, Ichiro Takeuchi, Apurva Mehta
High throughput experimental (HTE) techniques are an increasingly important way to accelerate the rate of materials research and development for many possible applications. However, there are very few publications on the reproducibility of the HTE results

Bridging the Pressure Gap in Electron Beam Induced Current Microscopy: Imaging Charge Transport in Metal Oxide Nanowires under Atmospheric Pressures

July 25, 2016
Ana Stevanovic, Jeyavel Velmurugan, Feng Yi, David A. LaVan, Andrei A. Kolmakov
We developed a versatile environmental cell for ambient pressure scanning electron microscopy (SEM) technique to study the interplay between surface reactivity and electronic properties of metal oxide nanowires such as SnO2, TiO2 and ZnO. We tested

Versatile fluidic cell for in-situ electrochemical measurements in SEM

July 25, 2016
Jeyavel Velmurugan, Ana Stevanovic, Feng Yi, David A. LaVan, Andrei Kolmakov
Electrochemical techniques such as like electrodeposition are crucially important for fabrication of nanostructured materials. The details of cluster nucleation and growth at early stages of electrodeposition are extremely important for morphology and
