Quantifying and Suppressing Proton Intercalation to Enable High-Voltage Zn-Ion Batteries

November 4, 2021
Author(s)
Fei Wang, Lauren E. Blanc, Qin Li, Antonio Faraone, Xiao Ji, Huaiyu H. Chen-Mayer, Rick L. Paul, Joseph Dura, Enyuan Hu, Kang Xu, Linda F. Nazar, Chunsheng Wang
We explore the Zn-ion intercalation mechanisms/interfacial dynamics of VPO 4F and quantify the water dynamics in water-in-salt (WISE) and hybrid aqueous-non aqueous electrolytes (HANEs). We demonstrate that H + intercalation dominates electrochemical

A Semi-Supervised Approach for Automatic Crystal Structure Classification

The structural solution problem can be a daunting and time consuming task. Especially in the presence of impurity phases, current methods such as indexing become more unstable. In this work, we apply the novel approach of semi-supervised learning towards

Superhydrophilic porous transport layer enhances effciency of polymer electrolyte membrane electrolyzers

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

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

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

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 L. 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
