Anisotropy Factors in Small-Angle Scattering for Dilute Rigid-Rod Suspensions

June 1, 2023
Author(s)
Jack Rooks, Peter H. Gilbert, Lionel Porcar, Yun Liu, Paul Butler
Alignment of anisotropic particles along specific orientations influences the mechanical and rheological properties of a material. Small-angle scattering techniques are widely used to probe this alignment through analysis of anisotropic two-dimensional

Extending Dual-Comb Spectroscopy Path Length to 14.5 km by Separating Receiver from Transmitter

June 1, 2023
Author(s)
Fabrizio Giorgetta, Esther Baumann, Brian Washburn, Nathan Malarich, J.-D. Deschenes, Ian Coddington, Nathan Newbury, Kevin Cossel
We present dual-comb spectroscopy across a 14.5-km path using remote receiver and data acquisition. This configuration results in lower link losses compared to open-path configurations with co-located transmitter and receiver.

Micromechanical Properties of Spherical and Facetted He Bubble Loaded Copper

June 1, 2023
Author(s)
Osman El Atwani, Jonathan Gigax, Rodney McCabe, Demircan Canadinc, Matthew Chancey, Jordan Weaver
Exploring new irradiation resistant materials requires understanding their mechanical responses to irradiation. Resistance to helium bubble formation and understanding bubble effects on the mechanical response of candidate materials are crucial factors to

Possible Genetic Risks from Heat-Damaged DNA in Food

June 1, 2023
Author(s)
Yong Woong Jun, Melis Kant, Erdem Coskun, Pawel Jaruga, Miral M. Dizdar, Eric T. Kool
Consumption of foods prepared at high temperatures has been associated with numerous health risks. To date, the chief identified source of risk has been small molecules produced in trace levels by cooking and react with healthy DNA upon consumption. Here

Simulation For All: The Atomic, Molecular, and Optical Science Gateway

June 1, 2023
Author(s)
kathryn hamilton, klaus bartschat, nicolas douguet, sudhakar pamidighantam, robert lucchese, Barry I. Schneider
A challenge facing the Atomic, \hboxMolecular}, and Optical Science (AMOS) community is the lack of a coordinated approach to using and sharing the computational tools and data that have grown organically in the theoretical community. The Atomic, Molecular

Exclusive Recognition of CO2 from Hydrocarbons by Aluminum Formate with Hydrogen-Confined Pore Cavities

May 31, 2023
Author(s)
Zhaoqiang Zhang, Zeyu Deng, Hayden Evans, Dinesh Mullangi, Chengjun Kang, Shing B. Peh, Yuxiang Wang, Craig Brown, John Wang, Pieremanuele Canepa, Anthony K. Cheetham, Dan Zhao
Exclusive capture of carbon dioxide (CO2) from hydrocarbons via adsorptive separation is an important technology in the petrochemical industry, especially for acetylene (C2H2) production. However, the physicochemical similarities between CO2 and C2H2
