Superhydrophilic porous transport layer enhances effciency of polymer electrolyte membrane electrolyzers

October 20, 2021
Author(s)
Benzhong Zhao, ChungHyuk Lee, Jason K. Lee, Kieran F. Fahy, Jacob LaManna, Elias Baltic, David Jacobson, Daniel Hussey, Aimy Bazylak
Hydrogen is widely regarded as a promising vehicle for renewable energy storage due to its versatility and high energy density. A prominent technology for hydrogen generation is the polymer electrolyte membrane (PEM) electrolyzer, which decomposes liquid

On the Cluster Formation of a-Synuclein Fibrils

October 19, 2021
Author(s)
Marija Dubackic, Ilaria Idini, Veronica Lattanzi, Yun Liu, Anne Martel, Ann Terry, Michael Haertlein, Juliette Devos, Andrew J. Jackson, Emma Sparr, Sara Linse, Ulf Olsson
The dense accumulation of α-Synuclein fibrils in neurons is considered to be strongly associated with Parkinson's disease. These intracellular inclusions, called Lewy bodies, also contain significant amounts of lipids. To better understand such

Spatially Resolved Potential and Li-Ion Distributions Reveal Performance-Limiting Regions in Solid-State Batteries

October 19, 2021
Author(s)
Elliot Fuller, Evgheni Strelcov, Jamie Weaver, Michael Swift, Joshua Sugar, Andrei Kolmakov, Nikolai Zhitenev, Jabez J. McClelland, Yue Qi, Joseph Dura, Alec Talin
The performance of solid-state electrochemical systems is intimately tied to the potential and lithium distributions across electrolyte–electrode junctions that give rise to interface impedance. Here, we combine two operando methods, Kelvin probe force

Dual-Modality Poly-^dL-Histidine Nanoparticles to Deliver Peptide Nucleic Acids and Paclitaxel for In Vivo Cancer Therapy

September 29, 2021
Author(s)
Aniket Wahane, Shipra Malik, Kuo-Chih Shih, Ravinder R. Gaddam, Chaohao Chen, Yun Liu, Mu-Ping Neih, Ajit Vikram, Raman Bahal
Cationic polymeric nanoformulations have been explored to increase the transfection efficiency of small molecules and nucleic acid-based drugs. However, excess of positive charge often leads to severe cell and tissue-based toxicity that restrict the

Hidden Complexity in the Chemistry of Ammonolysis-Derived "gamma-Mo2N": An Overlooked Oxynitride Hydride

September 14, 2021
Author(s)
Rick Paul, Shobhit A. Pandey, Chi Zhang, Daniah H. Ibrahim, Elise A. Goldfine, Jill K. Wenderott, Roberto dos Reis, Ionnis Spanopoulos, Mercouri Kanatzidis, Michael J. Bedzyk, Vinayak P. Dravid, Gabriela B. Gonzalez, Sossina M. Haile
Molybdenum nitrides have been employed in a variety of catalysis and electronic applications. For use in catalysis, the cubic  phase with nominal stoichiometry Mo2N and space group Fm3 ̅m is typically prepared by high temperature reaction of MoO3 with NH3

Pendellosung Interferometry Probes the Neutron Charge Radius, Lattice Dynamics, and Fifth Forces

September 10, 2021
Author(s)
Benjamin J. Heacock, Robert W. Haun, Michael G. Huber, Albert Henins, Robert C. Valdillez, Takuhiro Fujiie, Katsuya Hirota, Masaaki Kitaguchi, Hirohiko Shimizu, Takuya Hosobata, Masahiro Takeda, Yutaka Yamagata
Structure factors describe how incident radiation is scattered from materials such as silicon and germanium and characterize the physical interaction between the material and scattered particles. We used neutron Pendellösung interferometry to make

Neutron Scattering Studies of Materials for Hydrogen Storage

August 28, 2021
Author(s)
Ryan Klein, Hayden Evans, Benjamin Trump, Terrence J. Udovic, Craig Brown
Hydrogen storage presents a significant barrier to the widespread adaptation of hydrogen as an energy source in mobile and stationary applications. The development of new candidate hydrogen storage materials is therefore an outstanding goal in the field of

Highly Basic Clusters in the Herpes Simplex Virus 1 Nuclear Egress Complex Drive Membrane Budding by Inducing Lipid Ordering

August 24, 2021
Author(s)
Michael K. Thorsen, Alex Lai, Michelle W. Lee, David Hoogerheide, Gerard C. Wong, Jack H. Freed, Ekaterina Heldwein
During replication of herpesviruses, capsids escape from the nucleus into the cytoplasm by budding at the inner nuclear membrane. This process is mediated by the viral nuclear egress complex (NEC), but how the NEC interacts with lipids or generates

Enhanced Magnetic Interaction by Face-Shared Hydride Anions in 6H-BaCrO 2 H

August 16, 2021
Author(s)
Kentaro Higashi, Masayuki Ochi, Yusuke Nambu, Takafumi Yamamoto, Taito Murakami, Naoya Yamashina, Cedric Tassel, Yuki Matsumoto, Hiroshi Takatsu, Craig Brown, Hiroshi Kageyama
Studies on magnetic oxyhydrides have been almost limited to perovskite-based lattices with corner-sharing octahedra with a M‒H‒M (M: transition metal) angle of θ 180 °. Using a high-pressure method, we prepared BaCrO 2H with a 6H-type hexagonal perovskite

Relationship between Viscosity and Acyl Tail Dynamics in Lipid Bilayers

August 12, 2021
Author(s)
Michihiro Nagao, Elizabeth Kelley, Antonio Faraone, Makina Saito, Yoshitaka Yoda, Masayuki Kurokuzu, Shinichi Takata, Makoto Seto, Paul Butler
Membrane viscosity is a fundamental property that controls molecular transport and structural rearrangements in lipid membranes. Given its importance in many cell processes, various experimental and computational methods have been developed to measure the

Porous Covalent Organic Polymers for Efficient Fluorocarbon-Based Adsorption Cooling

Jian Zheng, Mohammad Wahiduzzman, Dushyant Barpaga, Benjamin Trump, Oliver T. Gutierrez, Praveen Thallapally, Shengqian Ma, B. P. McGrail, Guillaume Maurin, Radha K. Motkuri
We report the first exploration of fluorocarbon adsorption performances using defect-containing covalent–organic frameworks (COFs). Exceptionally high fluorocarbon R134a equilibrium capacities and unique overall linear-shaped isotherms are attributed to

Spin Reorientation in Antiferromagnetic Layered FePt5P
