Negative Cooperativity upon Hydrogen Bond-Stabilized O2 Adsorption in a Redox-Active Metal-Organic Framework

Julia Oktawiec, Henry Z. H. Jiang, Jenny G. Vitillo, Douglas A. Reed, Lucy E. Darago, Benjamin A Trump, Varinia Bernales, Harriet Li, Kristen A. Colwell, Hiroyasu Furukawa, Craig Brown, Laura Gagliardi, Jeffrey R. Long
The design of stable adsorbents capable of selectively capturing dioxygen with a high reversible capacity is a crucial goal in functional materials development

Inter-Kramers Transitions and Spin-Phonon Couplings in a Lanthanide-Based Single-Molecule Magnet

Duncan H. Moseley, Shelby E. Stavretis, Zhenhua Zhu, Mei Guo, Craig Brown, Mykhaylo Ozerov, Yongqiang Cheng, Luke L. Daemen, Rachael Richardson, Gary Knight, Komalavalli Thirunavukkuarasu, Anibal J. Ramirez-Cuesta, Jinkui Tang, Zi-Ling Xue
Spin-phonon coupling plays a critical role in magnetic relaxation in single-molecule magnets (SMMs) and molecular qubits. Yet, few studies of its nature have

Long-Range Magnetic Order in Hydroxide-Layer-Doped (Li1-x-yFexMnyOD)FeSe

Brandon Wilfong, Xiuquan Zhou, Huafei Zheng, Navneeth Babra, Craig Brown, Jeffrey W. Lynn, Keith M. Taddei, Johnpierre Paglione, Efrain E. Rodriguez
The (Li1-xFexOH)FeSe superconductor has been suspected to exhibit long-range magnetic ordering due to Fe substitution in the LiOH layer. However, no direct

Molecular Insight into Fluorocarbon Adsorption in Pore Expanded Metal-Organic Framework Analogs

Jian Zheng, Dushyant Barpaga, Benjamin A. Trump, Manish Shetty, Yanzhong Fan, Papri Bhattacharya, Jeromy J. Jenks, Cheng-Yong Su, Craig M. Brown, Guillaume Maurin, B. Peter McGrail, Radha Kishan Motkuri
The rapid growth in the global energy demand for space cooling requires the development of more efficient environmental chillers for which adsorption-based

Elusive Valence Transition in Mixed-Valence Sesquioxide Cs4O6

Ross H. Colman, H. Esma Okur, Winfried Kockelmann, Craig Brown, Annette Sans, Claudia Felser, Martin Jansen, Kosmas Prassides
Cs4O6 is a mixed valence molecular oxide with a cubic structure, comprising valency-delocalized O2 4/3- units and with properties highly sensitive to cooling

Anharmonic Acoustic Phonons and A-site Critical Fluctuations in the Lead Halide Perovskite CsPbBr3

M. Songvilay, Nathan Giles-Donovan, M. Bari, Z.-G. Ye, J. L. Minns, M. A. Green, Guangyong NMN Xu, Peter M. Gehring, K. Schmalzl, William D. Ratcliff, Craig Brown, D. Chernyshov, W. van Beek, Sandy Cochran, Christopher Stock
We apply neutron spectroscopy to investigate the transverse acoustic phonons in the lead halide CsPbBr3 near the three zone boundaries of the cubic Pm3m

Understanding Gas Storage in Cuboctahedral Porous Coordination Cages

Gregory R. Lorzing, Eric J. Gosselin, Benjamin A Trump, Arthur H. P. York, Arni Sturluson, Casey A. Rowland, Glenn P. A. Yap, Craig Brown, Cory M. Simon, Eric D. Bloch
Porous molecular solids are promising molecular solids are promising materials for gas storage applications. However, given the relative dearth of studies

Rattling Behavior in a Simple Perovskite NaWO3

Yuya Ikeuchi, Hiroshi Takatsu, Cedric Tassel, Craig Brown, Taito Murakami, Yuki Matsumoto, Yoshihiko Okamoto, Hiroshi Kageyama
A high-pressure reaction has allowed the preparation of stoichiometric tungsten bronze NaWO3 (Im-3). Specific heat (C;/T3 vs T) exhibits a round peak at 30 K
