What Causes the Anomalous Aggregation in Pluronic Aqueous Solutions?

May 28, 2018
Author(s)
Kuo-Chih Shih, Zhiqiang Shen, Ying Li, Martin Kroger, Shing-Yun Chang, Yun Liu, Mu-Ping Nieh, Hsi-Mei Lai
Pluronic (PL) block copolymers has been widely used as delivery carriers, molecular templates for porous media, process additive of affecting rheological behavior. Unlike most surfactant systems, where unimer transforms into micelle with increased

Structure and Dynamics of a Graphene Melt

May 22, 2018
Author(s)
Jack F. Douglas, Sinan Keten, Fernando Vargas-Lara, Wenjie Xia
We show by molecular dynamics simulation that bulk materials composed of graphene nanosheets exhibit fluid-like properties similar to linear polymer melts at elevated temperatures and that these materials transform into a glassy or “foam” state at low

Emerging investigators in materials science 2017-2018

May 21, 2018
Author(s)
Frank W. DelRio, Robert Riggleman
Materials Research Express is a multidisciplinary journal devoted to publishing cutting-edge experimental and theoretical research on the processing, structure, properties, and performance of all classes of materials, with an emphasis on the following

Controlling Pore Shape and Size of Interpenetrated Anion-Pillared Ultramicroporous Materials Enables Molecular Sieving of CO 2 Combined with Ultrahigh Uptake Capacity

May 16, 2018
Author(s)
Mengdie Jiang, Bin Li, Xili Cui, Qiwei Yang, Zongbi Bao, Yiwen Yang, Hui Wu, Wei Zhou, Banglin Chen, Huabin Xing
The separation of carbon dioxide (CO 2) from hydrocarbons is a critical process for the production of clean energy and high-purity chemicals. Adsorption based on molecular sieving is an energy-saving separation process; however most of molecular sieves

Superconformal Nickel Deposition in Through Silicon Vias: Experiment and Prediction

May 16, 2018
Author(s)
Trevor Braun, Daniel Josell, Thomas P. Moffat, Hyo Jong Lee, SH Kim
This work examines the filling of Through Silicon Vias (TSV) by Ni deposition from a NiSO4 + NiCl2 + H3BO3 electrolyte containing a branched polyethyleneimine suppressor previously. Feature filling occurs through the coupling of transport limited

Fine Tuning and Specific Binding Sites with a Porous Hydrogen-Bonded Metal-Complex Framework for Gas Selective Separations

May 14, 2018
Author(s)
Zongbi Bao, Danyan Xie, Ganggang Chang, Hui Wu, Liangying Li, Wei Zhou, Hailong Wang, Zhiguo Zhang, Huabin Xing, Qiwei Yang, Michaek J. Zaworotko, Qilong Ren, Banglin Chen
Research on HOFs has been developed for quite a long time; however, those with both established permanent porosities and functional properties are extremely rare due to weak hydrogen-bonding interactions among molecular organic linkers which are much more

A Metal-Organic Framework with Optimized Porosity and Functional Sites for High Gravimetric and Volumetric Methane Storage Working Capacities

April 24, 2018
Author(s)
Hui-Min Wen, Bin Li, Libo Li, Rui-Biao Lin, Wei Zhou, Guodong Qian, Banglin Chen
Extensive research has been devoted to develop new porous materials for high methane storage capacity. While great progress has been made in recent years, it still remains very challenging to target simultaneously high gravimetric and volumetric methane

Screened Moments and Extrinsic In-Gap States in Samarium Hexaboride

April 18, 2018
Author(s)
W. T. Fuhrman, J. R. Chamorro, P. A. Alekseev, J.-M. Mignot, T. Keller, Jose Rodriguez Rivera, Yiming Qiu, P. Nikolic, T. M. McQueen, Collin L. Broholm
The Kondo impurity effect in metals is the result of quantum-mechanical scattering of conduction electrons by magnetic impurities. 1 This process leads to exotic effects such as unconventional superconductivity and an effective electron mass enhanced by 2

Journal of Applied Crystallography: The First 50 Years and Beyond

April 1, 2018
Author(s)
Andrew J. Allen, Janos Hajdu, Garry J. McIntyre
The first issue of the Journal of Applied Crystallography appeared in April 1968. So, with this issue we celebrate its 50th birthday! We should start by expressing our appreciation for all the readers, authors, reviewers, editors and technical staff who

Glassy Phases in Organic Semiconductors

March 17, 2018
Author(s)
Chad R. Snyder, Dean M. DeLongchamp
Organic semiconductors may be processed from fluids using graphical arts printing and patterning techniques to create complex circuitry. Because organic semiconductors are weak van der Waals solids, the creation of glassy phases during processing is quite

Zero-field current switching of magnetic domains via chiral domain walls

March 16, 2018
Author(s)
Yufan Li, Qinli Ma, Daniel Gopman, Yury Kabanov, Robert D. Shull, C Chien
In ferromagnetic (FM) materials, the inherent exchange interaction, magnetic anisotropy, & dipolar forces dictate the domain walls (DWs), Bloch or N´eel, that separate magnetic moments. However, in FM thin films in contact with heavy metal (HM) with strong
