High-Resolution DNA Hybridization Kinetics Measurements with Double Gate FD-SOI Transistors

January 23, 2023
Author(s)
Seulki Cho, Alexander Zaslavsky, Curt A. Richter, Jacob Majikes, James Alexander Liddle, Francois Andrieu, Sylvain Barraud, Arvind Balijepalli
Double gate fully depleted SOI transistors operating in a remote gate configuration and under closed-loop feedback allow noise performance that exceeds their single gate counterparts by more than an order of magnitude. We leverage this high performance to

Failure mechanisms in DNA self-assembly: Barriers to single fold yield

February 23, 2021
Author(s)
Jacob Majikes, Paul Patrone, Anthony J. Kearsley, Michael P. Zwolak, James Liddle
Understanding the folding process of DNA origami is a critical steppingstone to the broader implementation of nucleic acid nanofabrication technology but is notably non-trivial. Origami are formed by several hundred cooperative hybridization events – folds

DNA Origami Design: A How-To Tutorial

January 8, 2021
Author(s)
Jacob Majikes, James Alexander Liddle
While the design and assembly of DNA origami are straightforward, its relative novelty as a nanofabrication technique means that the tools and methods for designing new structures have not been codified as well as they have for more mature technologies

Revealing thermodynamics of DNA origami folding via affine transformations

June 4, 2020
Author(s)
Jacob M. Majikes, Paul N. Patrone, Daniel R. Schiffels, Michael P. Zwolak, Anthony J. Kearsley, Samuel P. Forry, James A. Liddle
Structural DNA nanotechnology, as exemplified by DNA origami, has enabled the design and construction of molecularly precise objects for a myriad of applications. However, limitations in imaging, and other characterization approaches, make a quantitative

Modeling the Electromagnetic Scattering Characteristics of Carbon Nanotube Composites Characterized by 3D Tomographic Transmission Electron Microscopy

May 7, 2020
Author(s)
Ahmed M. Hassan, Md Khadimul Islam, Spencer On, Bharath Natarajan, Itai Stein, Noa Lachman, Estelle Cohen, Brian L. Wardle, Renu Sharma, James Alexander Liddle, Edward Garboczi
In nearly all prior modeling studies of the electromagnetic properties of carbon nanotube (CNT) composites, the three-dimensional (3D) shape and spatial distribution of the CNTs in the composite were unknown. Therefore, simplifying assumptions had to be

Low-temperature growth of carbon nanotubes catalyzed by sodium-based ingredients

May 27, 2019
Author(s)
Renu Sharma, Richard Li, Erica F. Antunes, Estekke Cohen, Akira Kudo, Luiz Acauan, Wei-Chang D. Yang, Chih-Ming Wang, Kehang Cui, Andrew Liotta, Ananth G. Rajan, Jules Gardner, David C. Bell, Michael S. Strano, James A. Liddle, Brian L. Wardle
Nanoparticle-catalytic synthesis of carbon nanostructures is an attractive route for producing 1-dimensional carbon nanomaterials, such as carbon nanotubes1 (CNTs), in large enough quantities for their multifunctional capabilities to be applied in

Nanoparticle Manufacturing - Heterogeneity through Processes to Products

August 15, 2018
Author(s)
Samuel M. Stavis, Jeffrey Fagan, Michael Stopa, James Alexander Liddle
Commercial products are now making use of the unique properties of nanoscale particles. However, common challenges of making nanoparticles into products still limit their impact. In this article, we review recent advances in nanoparticle manufacturing in

Research Update: Electron beam-based metrology after CMOS

July 19, 2018
Author(s)
James A. Liddle, Brian D. Hoskins, Andras Vladar, John S. Villarrubia
The strengths of and challenges facing electron-based metrology for post-CMOS technology are reviewed. Directed self-assembly, nanophotonics/plasmonics, and resistive switches and selectors, are examined as exemplars of important post-CMOS technologies

Subnanometer localization accuracy in widefield optical microscopy

July 11, 2018
Author(s)
Craig R. Copeland, Jon C. Geist, Craig D. McGray, Vladimir A. Aksyuk, James A. Liddle, Bojan R. Ilic, Samuel M. Stavis
The common assumption that precision is the limit of accuracy in localization microscopy and the typical absence of comprehensive calibration of optical microscopes lead to a widespread issue - overconfidence in measurement results with nanoscale

Aperture Arrays for Subnanometer Calibration of Optical Microscopes

September 28, 2017
Author(s)
Craig Copeland, Craig McGray, Jon Geist, James Alexander Liddle, Robert Ilic, Samuel Stavis
We fabricate and test subresolution aperture arrays as calibration devices for optical localization microscopy. An array pitch with a relative uncertainty of approximately three parts in ten thousand enables magnification calibration with subnanometer

Enhanced durability of CNT based hierarchical composites subjected to accelerated aging environments.

September 21, 2017
Author(s)
Ajay Krishnamurthy, Donald L. Hunston, Amanda L. Forster, Bharath NMN Natarajan, Sunny Wicks, Paul E. Stutzman, James A. Liddle, Aaron M. Forster, Brian L. Wardle
As carbon nanotube (CNT) based composites are increasingly being identified as viable aerospace materials, it is vital to study their environmental degradation characteristics. In this work, the durability of CNT reinforced hierarchical alumina fiber

Moisture Uptake Characterization in Nanocellulose Using Microwave Cavity

August 17, 2017
Author(s)
Caglar Emiroglu, Bharath N. Natarajan, Jeffrey W. Gilman, James Alexander Liddle, Jan Obrzut
Cellulose nanocrystal films with different helical modulation lengths are characterized. Films are obtained by tuning the rate of evaporation and surface functionalization. Dielectric constant measurements are performed and the water confinement is
