Three-dimensional Scanning Optical Tweezers

December 5, 2005
Author(s)
Thomas W. LeBrun, T W. Hwang, I Y. Park, Jun-Feng Song, Yong-Gu Lee, Nicholas G. Dagalakis, Cedric V. Gagnon, Arvind K. Balijepalli
… manipulation on an object, a complicated potential trap must be calculated and applied. We foresee that such … One of the candidates for implementing the calculated trap is scanning optical tweezers (SOT). SOT can be built by … order of a hundred Hertz. We need fast scanners to stably trap an object. In this study, we present our design of such …

The Use of Cause-and-Effect Analysis to Design a High Quality Nano-Cyto-Toxicology Assay

December 4, 2014
Author(s)
Matthias Rosslein, John T. Elliott, Marc L. Salit, Elijah Petersen, Cordula Hirsch, Harald Krug, Peter Wick
An important consideration in developing standards and regulations that govern the production and use of commercial nanoscale materials is the development of robust and reliable measurements to assess potential biological effects of these nanomaterials

Multidimensional Instrumentation Applied to Studies of Electrodeposition

February 9, 2007
Author(s)
Brian J. Polk, Felix Duvallet
Students of the experimental sciences have a need to learn how to interface multiple instruments to computers for the purpose of building effective data acquisition systems. For example, a requirement for better process control of electroplating demanded

Capillarity Induced Solvent?Actuated Bonding of Polymeric Microfluidic Devices

April 12, 2006
Author(s)
Jayna J. Shah, Jon C. Geist, Laurie E. Locascio, Michael Gaitan, Rao Mulpuri, Wyatt N. Vreeland
Rapid, robust and economical fabrication of fluidic microchannels is of fundamental importance for the successful development of disposable lab-on-a-chip devices. In this work, we present a solvent-actuated bonding method for fabricating polymeric

Vladimir P. Oleshko, Thomas F. Lam, Dmitry A. Ruzmetov, Paul M. Haney, Henri J. Lezec, Albert Davydov, Sergiy Krylyuk, John Cumings, Albert A. Talin
… and phase transformations that govern the operation of Li-ion batteries (LiBs) require detailed nanoscale 3D structural … Miniature all-solid-state heterostructure nanowire Li-ion batteries as a tool for engineering and structural …

Anomalous Modes Underpin Vortex Dynamics in Confined Bose-Einstein Condensates

January 1, 2001
Author(s)
D L. Feder, A A. Svidzinsky, A L. Fetter, Charles W. Clark
The dynamics of vortices in trapped Bose-Einstein condensates are investigated both analytically and numerically. In axially symmetric traps, the critical rotation frequency for metasability of an isolated vortex coincides with the largest vortex

Tightly Confined Surface Acoustic Waves as Microwave-to-Optical Transduction Platforms in the Quantum Regime

September 26, 2022
Author(s)
Ryan DeCrescent, Zixuan Wang, Poolad Imany, Robert Boutelle, Corey McDonald, Travis Autry, John Teufel, Sae Woo Nam, Richard Mirin
Surface acoustic waves (SAWs) coupled to quantum dots (QDs), trapped atoms and ions, and point defects have been proposed as quantum transduction platforms, yet the requisite coupling rates and cavity lifetimes have not been experimentally established

Experimental and Theoretical Evidence of Hydrogen Doping in Solution Processed Indium Gallium Oxide via Polymer Incorporation

July 23, 2020
Author(s)
Wei Huang, Joshua Tedesco, Po-Hsiu Chien, Kyle McMillen, Li Zeng, Subhrangsu Mukherjee, Binghao Wang, Yao Chen, Gang Wang, Yang Wang, Yanshan Gao, Michael Bedzyk, Dean DeLongchamp, Julia E. Medvedeva, Yan-Yan Hu, Tobin Marks, Antonio Facchetti

Chip-integrated visible-telecom entangled photon pair source for quantum communication

January 21, 2019
Author(s)
Xiyuan Lu, Qing Li, Daron Westly, Gregory Moille, Anshuman Singh, Vikas Anant, Kartik Srinivasan
Photon pair sources are fundamental blocks for quantum entanglement and quantum communication. Recent studies in silicon photonics have documented promising characteristics for photon pair sources within the telecommunications band, including sub-milliwatt

Diffractive Optics From Self-Assembled DNA

August 1, 2002
Author(s)
Zachary H. Levine
An algorithm is presented for assembling tiles into a variable spaced grating, the one-dimensional analogue of Fresnel zone plate. The algorithm supports blazing. The x-ray properties of such a grating, assumed to be constructed form DNA are estimated

A versatile bilayer resist for laser lithography at 405 nm on glass substrates

October 23, 2013
Author(s)
Quandou (. Wang, Ulf Griesmann
We describe a simple bilayer photoresist that is particularly well suited for laser lithography at an exposure wavelength of 405 nm on glass substrates, which is often used for the fabrication of binary diffractive optics and computer generated holograms
