Single self-assembled InAs/GaAs quantum dots in photonic nanostructures: the role of nanofabrication

June 13, 2018
Author(s)
Jin Liu, Kumarasiri Konthasinghe, Marcelo I. Davanco, John Lawall, Vikas Anant, Varun Verma, Richard Mirin, Jin Dong Song, Ben Ma, Ze Sheng Chen, Hai Qiao Ni, Zhi Chuan Niu, Kartik Srinivasan
Single self-assembled InAs/GaAs quantum dots are a promising solid-state quantum technology, with vacuum Rabi splitting, single-photon-level nonlinearities, and bright, pure, and indistinguishable single-photon generation having been demonstrated. In such

Metastable morphological states of catalytic nanoparticles

March 1, 2018
Author(s)
Pin A. Lin, Bharath N. Natarajan, Michael P. Zwolak, Renu Sharma
During the catalytic synthesis of graphene, nanotubes, fibers, and other nanostructures, many intriguing phenomena occur, such as phase separation, precipitation, and processes similar to capillary action. The underlying mechanism of these processes and

Predissociations in the 0 u + and 1 g States of K 2

… widths to O + / u spectral lines observed by monitoring trap loss. The fitted experimental widths aresignificantly …

Performance of Personal Alert Safety Systems in Laboratory and Full-Scale Experiments

April 18, 2002
Author(s)
Nelson P. Bryner, Daniel M. Madrzykowski, D W. Stroup, J H. Lee
In 1998, over 500 firefighters in the United States were trapped in structure fires that resulted in injury or death of firefighters. Firefighters can be quickly overcome by the heat or smoke of a fire and may be unable to alert other fire ground personnel

Analysis of Threshold Effects in Ultracold Atomic Collisions

July 1, 2000
Author(s)
F H. Mies, M -. Raoult
At the ultracold temperatures which occur in cold atom traps and Bose-Einstein condensates only a few partial waves contribute to the scattering of ground-state alkali atoms and cross sections are extremely sensitive to threshold effects. We present an

Polyelectrolyte Adsorption on Hydroxyapatite

November 1, 2001
Author(s)
Vincent A. Hackley
Hydroxyapatite (HAP) belongs to a family of structurally and chemically related, sparingly soluble calcium phosphate (CP) salts [1], and is the structural prototype for the principal mineral component of bone and teeth [2]. Well-defined synthetic HAP has

Twin-related grain boundary engineering of additively manufactured 316L stainless steel

December 1, 2025
Author(s)
Chenglu Tang, Jingfan Yang, Fan Zhang, Joseph Aroh, Ernest Porterfield, Barton Prorok, Xiaoyuan Lou
Twin-related grain boundary engineering (GBE) enhances the boundary-related degradation of materials, such as intergranular corrosion by incorporating a high density of twin boundaries. Conventional GBE typically requires one or multiple thermomechanical

The causal relationship between melt pool geometry and energy absorption measured in real time during laser-based manufacturing

December 16, 2021
Author(s)
Brian Simonds, Jack R. Tanner, Aly Artusio-Glimpse, Paul A. Williams, Niranjan Parab, Cang Zhao, Tao Sun
During laser powder bed fusion additive manufacturing, a protean pool of molten metal governs a complex energy absorption process as it presents as either a highly reflective surface, a deeply absorbing cavity (a keyhole), or some amalgamation thereof. To

Towards Absolute Viability Measurements for Bacteria

September 12, 2021
Author(s)
Joy Dunkers, Hariharan K. Iyer, Brynna H. Jones, Charles Camp, Stephan J. Stranick, Nancy Lin
Quantifying viable, vegetative bacteria is a critical measurand in healthcare diagnostics, food safety, and antimicrobial development. Viability determination has traditionally relied on such techniques as plate counting, colorimetric or fluorescent

Reproducibility and Robustness of a Real-Time Microfluidic Cell Toxicity Assay

May 15, 2011
Author(s)
Gregory A. Cooksey, John T. Elliott, Anne L. Plant
Numerous opportunities exist to apply microfluidic technology to high-throughput and high-content cell-based assays. However, maximizing the value of these assays for drug discovery, screening or toxicity evaluation, for example, will require validation of
