Nanoscopic Dynamics of Bicontinuous Microemulsions: Effect of Membrane-Associated Protein

July 28, 2017
Author(s)
V. K. Sharma, Douglas G. Hayes, Volker S. Urban, Hugh M. O'Neill, Madhu Sudan Tyagi, Eugene Mamontov
Bicontinous Microemulsions (BυE)generally consist of nanodomains formed by surfactant in a mixture of water and oil at nearly equal proportions and are potential candidates for the solubilization and purification of membrane proteins. Here we present the

New analysis of Fe VII

February 5, 2022
Author(s)
Alexander Kramida, A.N. Ryabtsev, Peter R. Young
New spectrograms of multiply ionized iron have been recorded and analyzed, targeting the Fe VII spectrum. As a result, several previously unknown spectral lines and energy levels have been identified in this spectrum. These new data have been analyzed

Probing Intrinsic Magnetization Dynamics of the Y3Fe5O12/Bi2Te3 Interface at Low Temperature

July 23, 2024
Author(s)
A. R. Will-Cole, Valeria Lauter, Alexander Grutter, Carsten Dubs, David Lidsky, Morris Lindner, Timmy Reimann, Nirjhar Bhattacharjee, Tzu-Ming Lu, Peter Sharma, Nichole Valdez, Charles Pearce, Todd Monson, Matthew Matzelle, Arun Bansil, Don Heiman, Nian Sun
Topological insulator–magnetic insulator (TI–MI) heterostructures hold significant promise in the field of spintronics, offering the potential for manipulating magnetization through topological surface state–enabled spin-orbit torque. However, many TI–MI

Lattice vibrations and the energy landscape of the isoelectronic semiconductor series CuBr, ZnSe, GaAs, and Ge: The special case of CuBr and its d-level chemistry

November 9, 2023
Author(s)
Joseph Woicik, Eric J. Cockayne, Eric L. Shirley, Igor Levin, Conan Weiland, Bruce D. Ravel, A. M. Milinda Abeykoon
We have examined the lattice vibrations and the energy landscape of the isoelectronic diamond and zincblende semiconductor series CuBr, ZnSe, GaAs, and Ge. Vibrations are found to be an increasing function of ionicity, with the cation sublattice always

The Single Residue K12 Governs the Exceptional Voltage Sensitivity of Mitochondrial Voltage-Dependent Anion Channel Gating

August 17, 2022
Author(s)
Van Ngo, Maria Queralt-Martin, Farha Khan, Lucie Bergdoll, Jeff Abramson, Sergey M. Bezrukov, Tatiana Rostovtseva, David Hoogerheide, Sergei Noskov
The voltage-dependent anion channel (VDAC) is a β-barrel channel of the mitochondrial outer membrane (MOM) that passively transports ions, metabolites, polypeptides, and single-stranded DNA. VDAC responds to a transmembrane potential by transitioning to a

Highly Tunable Magnetic Phases in Transition-Metal Dichalcogenide Fe 1/3+d NbS 2

April 5, 2022
Author(s)
Shan Wu, Zhijun Xu, Shannon Haley, Sophie Weber, Arani Acharya, Eran Maniv, Yiming Qiu, A. A. Aczel, Nicholas S. Settineri, Jeffrey Neaton, James Analytis, Robert Birgeneau
Layered transition metal dichalcogenides (TMDCs) host a plethora of interesting physical phenomena ranging from charge order to superconductivity. By introducing magnetic ions into 2H-NbS 2, the material forms a family of magnetic intercalated TMDCs T xNbS

Crystal Structure of Escherichia coli Protein ybgI

October 12, 2021
Author(s)
Jane E. Ladner, G Obmolova, A Teplyakov, P P. Khil, R D. Camerini-Otero, G L. Gilliland
The crystal structure determination of E. coli protein ybgI was undertaken as part of a structural genomics effort (http://s2f.carb.nist.gov) in order to assist with the functional assignment of the protein. The protein encoded by the ybgI gene of

Antiferromagnetic Order and Spin-Canting Transition in the Corrugated Square Net Compound Cu 3 (TeO 4 )(SO 4 ):H 2 O

July 19, 2021
Author(s)
Zhi-Cheng Wang, Kulatheepan Thanabalasingam, Jan P. Scheifers, Alenna Streeter, Gregory T. McCandless, Jonathan N. Gaudet, Craig Brown, Carlo U. Segre, Julia Y. Chan, Fazel Tafti
Strongly correlated electrons in layered perovskite structures have been the birthplace of high-temperature superconductivity, spin liquid, and quantum criticality. Specifically, the cuprate materials with layered structures made of corner sharing square

Competing Antiferromagnetic-Ferromagnetic States in d 7 Kitaev Honeycomb Magnet

December 14, 2020
Author(s)
Hector Vivanco, Benjamin Trump, Craig Brown, Tyrel M. McQueen
The Kitaev model is a rare example of an analytically solvable and physically instantiable Hamiltonian yielding a topological quantum spin liquid ground state. Here we report signatures of Kitaev spin liquid physics in the honeycomb magnet Li 3Co 2SbO 6

X-ray Scattering Studies of Reverse Osmosis Materials
