Accurate keyhole instability prediction in metal additive manufacturing through machine learning-aided numerical simulation

February 20, 2025
Author(s)
Jiahui Zhang, Runbo Jiang, Kangming Li, Pengyu Chen, Xiao Shang, Zhiying Liu, Brian Simonds, Qianglong Wei, Hongze Wang, Jason Hattrick-Simpers, Tao Sun, Anthony Rollet, Yu Zou
A primary obstacle impeding the use of metal additive manufacturing technologies in fatigue-sensitive applications is the presence of porosity, primarily caused by keyhole instability. To tackle this challenge, it is imperative to accurately forecast

Role of NEIL1 in genome maintenance

Author(s)
Amanda McCullough, Irina Minko, Michael Luzadder, Jamie Zuckerman, Pawel Jaruga, Vladimir Vartanian, M Miral Dizdar, R. Stephen Lloyd
Phylogenetic analyses of DNA glycosylases that function in the initiation step of base excision repair reveal a high degree of conservation within the genes encoding Nei-like DNA glycosylase 1 (NEIL1). In concert with other glycosylases, this enzyme is an

Sanjay Rekhi, David Kuhn, Kim Schaffer, Murugiah Souppaya, Noah Waller, Nelson Hastings, Michael Ogata, William Barker
NIST hosted an in-person, all-day workshop on February 27, 2024, to discuss existing and emerging cybersecurity threats and mitigation techniques for semiconductors throughout their life cycle. The workshop obtained valuable feedback from industry

Quantum Emitters Induced by High Pressure and UV Laser Irradiation in Multilayer GaSe

Sinto Varghese, Sichenge Wang, Bimal Neupane, Bhojraj Bhandari, Yan Jiang, Roberto Gonzalez Rodriguez, Sergiy Krylyuk, Albert Davydov, Hao Yan, Yuanxi Wang, Anupama Kaul, Jingbiao Cui, Yuankun Lin
In this work, we report on defect generation in multilayer GaSe through hydrostatic pressure quenching and UV laser irradiation. The Raman line width from the UV 266 nm irradiated sample is much wider than that in pressure-quenched GaSe, corresponding to a

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

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

Effect of ''glancing'' collisions in the cold atom vacuum standard

February 12, 2025
Author(s)
Stephen Eckel, Daniel Barker, James A. Fedchak, Jacek Klos, Julia Scherschligt, Eite Tiesinga
We theoretically investigate the effect of "glancing" collisions on the ultra-high-vacuum pressure readings of the cold-atom vacuum standard (CAVS), based on either ultracold $^7$Li or $^87}$Rb atoms. Here, glancing collisions are those collisions between

Cryogenic photonic resonator with 10-17/s drift

February 11, 2025
Author(s)
Wei Zhang, William Milner, Jun Ye, Scott Papp
Thermal noise is the predominant instability in the provision of ultrastable laser frequency by reference to a cavity. Reducing the thermal-noise limit of a cavity means either making it larger to spread thermal fluctuations, reducing the sensitivity of

Entanglement Routing in Quantum Networks: A Comprehensive Survey

February 11, 2025
Author(s)
Amar Abane, Michael Cubeddu, Van Sy Mai, Abdella Battou
Entanglement routing in near-term quantum networks consists of choosing the optimal sequence of local entanglements to combine through swapping operations to establish end-to-end entanglement between two distant nodes on a quantum network. Similar to

Nanophotonic oscillators for laser conversion beyond an octave

February 11, 2025
Author(s)
Grant Brodnik, Haixin Liu, David Carlson, Jennifer Black, Scott Papp
Many uses of lasers place the highest importance on access to specific wavelength bands. For example, mobilizing optical-atomic clocks for a leap in sensing requires compact lasers at frequencies spread across the visible and near infrared. Integrated
