Peng Luo, Abhishek Jaiswal, Yanqin Zhai, Zhikun Cai, Nathan P. Walter, Long Zhou, Dawei Ding, Ming Liu, Rebecca Mills, Andrey Podlesnyak, Georg Ehlers, Antonio Faraone, Haiyang Bai, Weihua Wang, Y. Z.
By employing quasi-elastic neutron scattering, we studied the atomic-scale relaxation dynamics and transport mechanism of La 50Ni 15Al 35 and Ce 69Cu 20Al 10Nb 1 Studied by Quasi-Elastic Neutron Scattering metallic glass melts in the temperature range of

Collective Dynamics in Lipid Membranes Containing Transmembrane Peptides

June 21, 2021
Author(s)
Elizabeth Kelley, Paul Butler, Michihiro Nagao
Biological membranes are composed of complex mixtures of lipids and proteins that influence each other's structure and function. The biological activities of many channel-forming peptides and proteins are known to depend on the material properties of the

Copper-binding anticancer peptides from the piscidin family: an expanded mechanism that encompasses physical and chemical bilayer disruption

June 16, 2021
Author(s)
Fatih Comert, Frank N. Heinrich, Ananda Chowdhury, Mason Schoeneck, Caitlin Darling, Kyle Anderson, M. Daben J. Libardo, Alfredo Angeles-Boza, Vitalii I. Silin, Myriam Cotten, Mihaela Mihailescu
In the search for novel broad‑spectrum therapeutics to fight chronic infections, inflammation, and cancer, host defense peptides (HDPs) have garnered increasing interest. Characterizing their biologically‑active conformations and minimum motifs for

Probing Clustering Dynamics between Silicon and PAA or LiPAA Slurries under Processing Conditions

June 3, 2021
Author(s)
Mary Burdette-Trofimov, Beth Armstrong, Ryan Murphy, Luke Heroux, Mathieu Doucet, Alexander Rogers, Gabriel Veith
This work explores the complex interplay between slurry aggregation, agglomeration, and conformation (i.e. shape) of poly(acrylic acid) (PAA) and lithiated poly(acrylic acid) (LiPAA) based silicon slurries as a function of shear rate, and the resulting

Biodegradable Zwitterionic Poly(Carboxybetaine) Microgel for Sustained Delivery of Antibodies with Extended Stability and Preserved Function

June 2, 2021
Author(s)
Amir Erfani, Abanoub Hanna, Payam Zarrintaj, Saeed Manouchehri, Katie Weigandt, Clint P. Aichele, Joshua D. Ramsey
Many recent innovative treatments are based on monoclonal antibodies (mAbs) and other protein therapies. Nevertheless, sustained subcutaneous, oral or pulmonary delivery of such therapeutics are limited by the poor stability, short half-life, and non

Imaging with Neutrons

June 1, 2021
Author(s)
Daniel Hussey, Gilberto Artioli
By exploiting the penetration and scattering properties of neutrons, images of matter in two or three dimensions reveal information unobtainable with other probes. Despite the limitation in brilliance of neutron sources, several neutron-based imaging

Chopped Cold Neutron Beam Activation Analysis

May 17, 2021
Author(s)
Danyal J. Turkoglu, Heather H. Chen-Mayer
A linear fast neutron beam chopper has been deployed at the prompt gamma activation analysis instrument, enabling in-beam activation analysis of short-lived (T1/2 > 10 ms) neutron capture products without needing sample transfer. This paper describes the

An Optical Investigation of the Heavy Fermion Normal State in Superconducting UTe 2

May 11, 2021
Author(s)
Sirak Mekonen, Chang-Jong Kang, Dipanjan Chaudhuri, David Barbalas, Sheng Ran, Gabriel Kotliar, Nicholas Butch, N. Armitage
The recently discovered superconductor, UTe 2, has attracted immense scientific interest due to the experimental observations that suggest odd-parity superconductivity. It is believed that the material becomes a heavy-fermion metal at low temperatures

Compact Thermal Actuation by Water and Flexible Hydrophobic Nanopore

April 29, 2021
Author(s)
Miroslaw Chorazewski
Efficient and compact energy conversion is at the heart of sustainable development of humanity. In this work it is demonstrated that hydrophobic flexible nanoporous materials can be used for thermal-to-mechanical energy conversion when coupled with water

A Rod-Packing Hydrogen-Bonded Organic Framework with Suitable Pore Confinement for Benchmark Ethane/Ethylene Separation

April 26, 2021
