Observation of Interpenetrated Topology Isomerism for Covalent Organic Frameworks with Atom-resolution Single Crystal Structures

November 9, 2023
Baoqiu Yu, Wenliang Li, Jing-Hong Li, Rui-Biao Lin, Hailong Wang, Xu Ding, Yucheng Jin, Xiya Yang, Hui Wu, Wei Zhou, Jingping Zhang, Jianzhuang Jiang
Rational control and understanding of isomerism are of significance but still remain a great challenge in reticular frameworks in particular for covalent organic frameworks (COFs) due to the complicated synthesis and energy factors. Herein, reaction of 3,3

Elastic Behavior of Orientation-Correlated Grains in Multiphase Aggregates

October 1, 2023
Thomas Gnaupel-Herold
Diffraction elastic constants (DECs) describe the elastic response of a subset of orientation-correlated grains which share a common lattice vector. DECs reflect the elastic behaviour of the single-crystal constituents through their dependence on grain

Classification and Authentication of Materials using Prompt Gamma Ray Activation Analysis

July 12, 2023
Nathan Mahynski, Jacob Monroe, David Sheen, Rick L. Paul, Heather H. Chen-Mayer, Vincent K. Shen
Prompt gamma ray activation analysis (PGAA) is a non-destructive nuclear measurement technique that quantifies isotopes present in a sample. Here, we use PGAA spectra to train different types of models to elucidate how discriminating these spectra are for

Investigating the Cut-off Effect of n-alcohols on Lipid Movement: A Biophysical Study

July 5, 2023
Michael H. Nguyen, Dominik Dziura, Mitchell DiPasquale, Stuart R. Castillo, Elizabeth Kelley, Drew Marquardt
Cellular membranes are responsible for absorbing the effects of external perturbants for the cell's survival. Such perturbants include small ubiquitous molecules like n-alcohols which were observed to exhibit anesthetic capabilities, with this effect

H2 Generation by the 10B(n,alpha)7Li Reaction in High Temperature Water

July 4, 2023
Alan Keith Thompson, Mohamad Al-Sheikhly, Steven Guerin, David Bartels, Cameron Goodwin, Sangho Nam
H2 produced in water from the 10B(n,α)7Li fission reaction has been measured up to 300 oC. Thermal energy neutrons from the Rhode Island Nuclear Science Center's 2 MW reactor interact with boric acid-containing water in temperature-controlled high-pressure

Detection of a Pair Density Wavestate in UTe2

June 28, 2023
Qiangqiang Gu, Joseph Carroll, Shuqiu Wang, Sheng Ran, Christopher Broyles, Hasan Siddiquee, Nicholas Butch, Shanta Saha, Johnpierre Paglione, J. Davis, Xiaolong Liu

Mitocans Induce Lipid Flip-Flop and Permeabilize the Membrane to Signal Apoptosis

June 6, 2023
Stuart R. Castillo, Michael H. Nguyen, Mitchell DiPasquale, Elizabeth Kelley, Drew Marquardt
Pancratistatin (PST) and narciclasine (NRC) are natural therapeutic agents which exhibit specificity towards the mitochondria of cancerous cells and initiate apoptosis. Unlike traditional cancer therapeutic agents, PST and NRC are effective, targeted, and

Quantifying Reactor Power Noise - A Case Study on NIST Research Reactor

May 26, 2023
Anil Gurgen, Dagistan Sahin, James R. Whipple
Water cooled reactors experience reactivity changes when voids are present in the coolant. The fraction of coolant in the core diminutions in the event of boiling, and the reactivity feedback can either be positive due to reducing neutron absorption in the
