Design and Characterization of an Architecturally Perfect Family of Linear Low-Density Polyethylenes (LLDPEs) by Multi-Detector Size Exclusion Chromatography

March 27, 2020
Author(s)
Sara V. Orski, Luke Kassekert, Wesley Farrell, Grace A. Kenlaw, Marc Hillmyer, Kathryn L. Beers
Separations of commercial polyethylenes, which often involve mixtures and copolymers of linear, short-chain, and long-chain branched chains, can be very challenging to optimize as species with similar hydrodynamic sizes or solubility often co-elute in

Cone-Spiral Magnetic Ordering Dominated Lattice Distortion and Giant Negative Thermal Expansion in Fe-Doped MnNiGe Compounds

March 1, 2020
Author(s)
Feiran Shen, Houbo Zhou, Fengxia Hu, Jian-Tao Wang, Sihao Deng, Baotian Wang, Hui Wu, Qingzhen Huang, Jing Wang, Jie Chen, Lunhua He, Jiazheng Hao, Zibing Yu, Feixiang Liang, Tianjiao Liang, Jirong Sun, Baogen Shen
Negative thermal expansion (NTE) has emerged as one of intense research topics to meet the demands of precision industry for compensating positive thermal expansion (PTE) properties. The adjustment of NTE behavior is the key for tailoring thermal expansion

Engineered Sulfur-MoS2-Graphene Heterostructure Cathodes for Diagnostics of Nanoscale Electrochemical Processes in High Energy Density Li-S Batteries

August 5, 2019
Author(s)
Vladimir P. Oleshko, William R. McGehee, Saya Takeuchi, Siyuan Zhang, Andrei A. Kolmakov, Jabez J. McClelland, Christopher L. Soles
Lithium-sulfur (Li-S) batteries have recently attracted enormous attention because of high theoretical specific energy (2600 Wh kg-1) and high specific capacity (1672 mAhg-1), as well as the low cost, natural abundance, and nontoxicity of elemental sulfur

Optimizing Self-Consistent Field Theory Block Copolymer Models with X-Ray Metrology

February 12, 2018
Author(s)
Adam F. Hannon, Daniel Sunday, Alec Bowen, Gurdaman Khaira, Jiaxing Ren, Paul Nealey, Juan de Pablo, Regis J. Kline
A block copolymer self-consistent field theory (SCFT) model is used for direct analysis of experimental X-ray scattering data obtained from thin films of polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA) made from directed self-assembly. In a departure

Key Recovery Attack for All Parameters of HFE-

June 4, 2017
Author(s)
Jeremy Vates, Daniel Smith-Tone
Recently, by an interesting confluence, multivariate schemes with the minus modifier have received attention as candidates for multivariate encryption. Among these candidates is the twenty year old HFE – scheme originally envisioned as a possible candidate

Tunable spin-spin interactions and entanglement of ions in separate controlled potential wells

August 7, 2014
Author(s)
Andrew C. Wilson, Yves Colombe, K. R. Brown, Emanuel H. Knill, Dietrich G. Leibfried, David J. Wineland
Inspired by the ideas of Richard Feynman, 1 David Deutsch, 2 Seth Lloyd 3 and others, researchers in the field of quantum information processing and simulation seek to harness the quantum-mechanical properties of well-controlled laboratory systems to
