Scalable Bottom-Up Synthesis of Nanoporous Hexagonal Boron Nitride (h-BN) for Large-Area Atomically Thin Ceramic Membranes

February 14, 2025
Author(s)
Andrew Naclerio, Peifu Cheng, Saban Hus, John Diulus, Marti Checa, Ivan Vlassiouk, William Fissel, Liam Collins, Matthew Coupin, Jamie Warner, Andrei Kolmakov, An-Ping Li, Piran Ravichandran Kidambi
Nanopores embedded within monolayer hexagonal boron nitride (h-BN) offer possibilities of creating atomically thin ceramic membranes with unique combinations of high permeance (atomic thinness), high selectivity (via molecular sieving), increased thermal

Scattering Insights into Shear-Induced Scission of Rodlike Micelles

January 23, 2025
Author(s)
Guan-Rong Huang, Ryan Murphy, Lionel Porcar, Chi-Huan Tung, Changwoo Do, Wei-Ren Chen
Studying the scission of rodlike micelles under mechanical forces is essential for understanding their stability and behavior in industrial applications. Mechanical stress can fragment these micelles, impacting performance. Investigating this process

Fabrication and characterization of low-loss Al/Si/Al parallel plate capacitors for superconducting quantum information applications

January 22, 2025
Author(s)
Raymond Simmonds, Sudhir Sahu, Trevyn Larson, Florent Lecocq, Tongyu Zhao, Anthony McFadden
The application of parallel plate capacitors composed of aluminum-contacted, crystalline silicon fins for use in superconducting circuits is explored by evaluating the performance of superconducting lumped element resonators and transmon qubits. High

Well characterized polyethyleneimine/carboxylated polyethylene glycol functionalized gold nanoparticles as prospective nanoscale control materials for in vitro cell viability assays: particle characterization and toxicity test in eight mammalian cell line

January 7, 2025
Author(s)
Vytas Reipa, Vincent Hackley, Alessandro Tona, Min Beom Heo, Ye Ryeong Lee, Tae Geol Lee, Aaron Johnston-Peck, Tae Joon Cho
Safety screening of manufactured nanomaterials (MNMs) is essential for their adoption by consumers and the marketplace. Lately, animal-based testing is replaced by mechanistically informative in vitro assays due to requirements of regulatory agencies. Cell

Multiplexed SERS Detection of Serum Cardiac Biomarkers Using Plasmonic Metasurfaces

October 15, 2024
Author(s)
Peng Zheng, Lintong Wu, Piyush Raj, Jeong Hee Kim, Santosh Paidi, Stephen Semancik, Ishan Barman
Surface-enhanced Raman spectroscopy (SERS) possesses exquisite molecular-specific properties with single-molecule sensitivity. Yet, translation of SERS into a quantitative analysis technique remains elusive owing to considerable fluctuation of the SERS

Ultrahigh reflectivity photonic crystal membranes with optimal geometry

July 30, 2024
Author(s)
Feng Zhou, Yiliang Bao, Jason Gorman, John R. Lawall
Photonic crystal (PhC) structures with subwavelength periods are widely used for diffractive optics, including high reflectivity membranes with nanoscale thickness. Here, we report on a design procedure for 2D PhC silicon nitride membrane mirrors providing

Morphologic alterations across three levels of biological organization following oral exposure to silver-polymer nanocomposites in Japanese medaka (Oryzias latipes)

July 5, 2024
Author(s)
Melissa Chernick, Alan Kennedy, Treye Thomas, Keana C. K. Scott, Joana Sipe, Christine Hendren, Mark Wiesner, David Hinton
Polymer nanocomposites have diverse industrial and commercial uses. While many toxicity studies have assessed the individual materials (e.g., polymer, nanomaterial) comprising nanocomposites, few have examined the potential toxicity of the nanocomposite as

Fully integrated multifunctional sensor and open-source ASIC for flexible wearables

June 25, 2024
Author(s)
Anhang Li, Hongyi Wu, Ashbir Aviat Fadila, Chanho Kye, Arvind Balijepalli, Johan Euphrosine, Tim Ansell, Nigel Coburn, Sachin Nadig, Mehdi Saligane
The open-source hardware movement has made significant progress over the past few years. Increasingly, more individuals are engaging with and participating in the open-source chip design community - not only to design their own chips with the available

Quantifying Mechanical Abrasion of AgNP Nanocomposites used in 3D Printing: Influence of AgNP content on abrasion products and rate of microplastic production

June 7, 2024
Author(s)
Joana Sipe, William Berger, Nathan Bossa, Melissa Chernick, Keana C. K. Scott, Alan Kennedy, Treye Thomas, Christine Ogilvie, Mark Wiesner
Nanomaterials are used in polymer composites to enhance plastic products' properties. Silver nanoparticles (AgNPs) are added to composites for their antimicrobial and fungicidal properties. Polyethylene terephthalate glycol polymer (PETG) AgNP composite

Dealloyed Pt74Ni26 and Pt26Ni74 Electrodeposited Thin Film Electrocatalysts for Oxygen Reduction

May 30, 2024
Author(s)
Carlos Hangarter, Eric Rus, Yihua Liu, Jaw Wook Shin, Vladimir Oleshko, Hyun Wook Ro, Russell Composto, Christopher Soles, Joseph A. Dura, Gery R. Stafford, Leonid Bendersky, Thomas P. Moffat
Pt100-xNix alloys are among the most active binary alloys for electrocatalysis of the oxygen reduction reaction (ORR) in PEM fuel cells. Electrodeposition and microstructure of thin films close to Pt75Ni25 and Pt25Ni75 stoichiometry are described and their
