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

Eyal Gerecht, V. A. Bhupathiraju, John Nicholson, Dazhen Gu, Yan Zhuang, Fernando R. Morales, Xin Zhao, Ric Zannoni, Sigfrid Yngvesson
… lift-off lithography of the antenna (gold), and reactive ion etching (RIE) or wet etching of the NbN. Receiver noise …

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

August 25, 2020
Author(s)
Qinyi Fu, Nisha Verma, Benjamin S. Hsiao, Francisco J. Medellin-Rodriguez, Peter Beaucage, Christopher Stafford, Benjamin M. Ocko
Scarcity of freshwater is becoming a world crisis. In a recent annual risk report, the World Economic Forum lists it in their greatest global risk category. Currently, about four billion people live under conditions of severe water scarcity for at least

Creating a Mass Spectral Reference Library for Oligosaccharides in Milk

July 3, 2018
Author(s)
Concepcion A. Remoroza, Tytus D. Mak, M. L. De Leoz, Yuri A. Mirokhin, Stephen E. Stein
We report the development and availability of a mass spectral reference library for oligosaccharides in human milk. This represents a new variety of spectral library that includes consensus spectra of compounds annotated through various data analysis

Spin-Orbit Coupled Molecular Quantum Magnetism Realized in Inorganic Solid

September 21, 2016
Author(s)
Sang-Youn Park, S.-H. Do, K.-Y. Choi, J.-H. Kang, Dongjin Jang, B. Schmidt, Manuel Brando, B.-H. Kim, D.-H. Kim, Nicholas Butch, Seongsu Lee, Sungdae Ji
The molecular magnetism, representing an isolated spin state, is of particular interest due to characteristics of quantum magnetism with quantum tunneling phenomena underlying qubits or molecular spintronics for the quantum information devices. Such

Complex Structures of Different CaFe 2 As 2 Samples

February 18, 2014
Author(s)
Bayrammurad Saparov, Claudia Cantoni, Minghu Pan, Thomas C. Hogan, William D. Ratcliff, Stephen D. Wilson, Katharina Fritsch, Bruce D. Gaulin, Athena S. Sefat
We use temperature-dependent X-ray and neutron diffraction, low-temperature scanning tunneling microscopy, and room-temperature scanning-transmission electron-microscopy, to investigate the interplay between magnetism and crystal structures in three CaFe
