Colloid-Like Solution Behavior of Computationally Designed Coiled Coil Bundlemers

January 15, 2022
Author(s)
Nairiti J. Sinha, Rui Guo, Rajkumar Misra, Jeffrey Fagan, Antonio Faraone, Christopher J. Kloxin, Jeffery G. Saven, Grethe V. Jensen, Darrin J. Pochan
The use of colloidal theory for describing protein-protein interactions is a topic of ongoing debate in the biophysical community. This contention stems from the unavailability of synthetic protein-like model particles that are amenable to systematic

Polyvinyl Acetate-Based Polymer Host for Optical and Far-Infrared Spectroscopy of Individualized Nanoparticles

January 15, 2021
Author(s)
Jeffrey Fagan, Henry Wladkowski, Julian Duarte, Shashank R. Nandyala, Joshua Walker, Subash Kattel, Jeffrey Blackburn, Jon Pikal, William D. Rice
Preparation techniques for producing films of individualized, solution dispersed nanoparticles (NPs) for optical spectroscopy are often technically challenging and tailored for a specific NP system. In this work, we present a rapid, easy, and economical

Selective Filling of n-Hexane in a Tight Nanopore

January 12, 2021
Author(s)
Jeffrey Fagan, Haoran Qu, Archith Rayabharam, Narayana Aluru, Xiaojian Wu, Peng Wang, Yunfeng Li, YuHuang Wang
Molecular sieving may occur when two similarly sized molecules compete for a nanopore. This size-selectivity generally favors the adsorption of molecules with smaller kinetic diameter into the pore while excluding larger ones. In nearly all known examples

Brightly Luminescent CsPbBr3 Nanocrystals through Ultracentrifugation

July 30, 2020
Author(s)
Jeffrey Fagan, Erik K. Hobbie, Aaron Forde, Richard D. Schaller, salim thomas, samuel brown, Matthew B. Kurtti, dmitri kilin
Colloidal lead-halide-perovskite nanocrystals (NCs) offer broad color tunability with bright photoluminescence (PL), fast lifetime, and narrow spectral linewidth. Because emission is tuned primarily through chemical composition, quantum confinement and

DNA-directed nanofabrication of high-performance carbon nanotube field-effect transistors

May 22, 2020
Author(s)
Ming Zheng, Jeffrey A. Fagan, Jason K. Streit, Mengyu Zhao, Yahong Chen, Kexin Wang, Zhi Zhu, Wei Sun
Scaling the channel pitch of field-effect transistors (FETs) is one prerequisite towards future ultra-scaled technology nodes. While lithography has been the foundational tool during the scaling of bulk materials, bio- fabrication is promising for

Precise pitch-scaling of ultra-scaled carbon nanotube arrays within 3D DNA nano-trenches

May 22, 2020
Author(s)
Jason K. Streit, Jeffrey Fagan, Ming Zheng, Wei Sun, Peng Yin, Jie Shen, Zhao Zhao, Hareem Maune
Precise assembly of carbon nanotubes (CNTs) into densely-aligned uniformly parallel arrays has been the missing link towards the emerging ultra-scaled post-Si technology nodes specified in the International Technology Roadmap for Semiconductors (ITRS)

Separation of Specific Single Enantiomer Single-Wall Carbon Nanotubes in the Large Diameter Regime

November 19, 2019
Author(s)
Jeffrey A. Fagan, Ming Zheng, Sofie Cambre, Wim Wenseleers, Benjamin Flavel, Han Li, Stephanie Reich, Georgy Gordeev, Oisin Garrity, Naga Peyyety, Ralph Krupke, Pranauv Selvasundaram
Enantiomer level isolation of single-wall carbon nanotubes (SWCNTs) in high concentration and purity for nanotubes greater than 1.1 nm in diameter is demonstrated for the first time using a twostage aqueous two-phase extraction (ATPE) technique. In total 5

Global alignment of solution-based single-wall carbon nanotube films via machine-vision controlled filtration

September 11, 2019
Author(s)
Jeffrey A. Fagan, Angela R. Hight Walker, Adam J. Biacchi, Joshua S. Walker, William D. Rice, Thomas Searles, Valerie A. Kuehl
Over the past decade, substantial progress has been made in the chemical processing (chiral enrichment, length sorting, handedness selectivity, and filling substance) of single- wall carbon nanotubes (SWCNTs). Recently, it was shown that large

Structural Insights into DNA-Stabilized Silver Clusters

May 10, 2019
Author(s)
Danielle Schultz, Robert G. Brinson, Fahriye N. Sari, Jeffrey Fagan, Christina Bergonzo, Nancy Lin, Joy Dunkers
The structure and dynamics of Ag complexes derived from single stranded DNA (ssDNA) is less understood than their double stranded (dsDNA) counterparts despite their great promise as fluorescent biological probes and sensors. In this work, we seek new
