February 23, 2023
Author(s)
Keiichiro Maegawa, Fan Zhang, Qiaxian Johnson, Mihaela Jitianu, Tan Wai Kian, Go Kawamura, Atsunori Matsuda, Andrei Jitianu
Layered double hydroxides (LDHs) are mixed M(II) and M(III) hydroxides with positively charged lamellar brucite layers and interlayered anions. LDHs attracted significant attention due to their anion and cation-exchange ability, adsorption capacity, and

Dynamic structural and microstructural responses of a metal organic framework type material to carbon dioxide under dual gas flow and supercritical conditions

February 1, 2023
Author(s)
Andrew J. Allen, Eric J. Cockayne, Winnie Wong-Ng, Jeffrey Culp, Ivan Kuzmenko
The structural and microstructural responses of a model metal-organic framework (MOF) material, Ni(3-Methy-4,4'-bipyridine)[Ni(CN)4] (Ni-BpyMe or PICNIC 21), to CO2 adsorption and desorption are reported for in situ small-angle X-ray scattering (SAXS) and

Multiscale Green's functions for modeling graphene and other Xenes

January 27, 2023
Author(s)
Vinod Tewary, Edward Garboczi
We give a review of the multiscale Green's function method for modeling modern two-dimensional nanomaterials such as graphene and other Xenes. The method is applicable to materials at different space and time scales and is computationally efficient. This

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

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

Voltage Modulated Magnetic Anisotropy of Rare Earth Iron Garnet Thin Films on a Piezoelectric Substrate

December 19, 2022
Author(s)
Miela Gross, Walid Al Misba, Kensuke Hayashi, Dhritiman Bhattacharya, Daniel Gopman, Jayasimha Atulasimha, Caroline Ross
Voltage-tuning of the magnetic anisotropy is dempnstrated in ferrimagnetic insulating rare earth iron garnets on a piezoelectric substrate, (011)-oriented PMN-PT. A yttrium-substituted dysprosium iron garnet (YDyIG) film 42 nm thick is grown via pulsed

Efficient chip-based optical parametric oscillators from 590 nm to 1150 nm

December 2, 2022
Author(s)
Jordan Stone, Xiyuan Lu, Gregory Moille, Kartik Srinivasan
Optical parametric oscillators are a ubiquitous technology used to generate coherent light at frequencies not accessible by conventional laser gain. However, chip-based parametric oscillators operating in the visible spectrum have suffered from pump-to

Reflow transfer for conformal three-dimensional microprinting

November 24, 2022
Author(s)
Gary Zabow
From microcircuits to metamaterials, micropatterning surfaces adds valuable functionality. For non-planar surfaces, however, incompatibility with conventional microlithography requires transferring originally planar micropatterns onto those surfaces but

Introduction of nanoscale positive controls for nanotoxicology: A new aspect of utilization of stability-enhanced Gold-Polyethyleneimine conjugates (Au-PEIs)
