Scalable and Environmentally Friendly Synthesis of Hierarchical Magnetic Carbon Nanosheet Assemblies and Their Application in Water Treatment
Yi Shen,Ling Li,Zhihui Zhang +2 more
TL;DR: In this article, a facile synthesis of hierarchical magnetic carbon nanosheet assemblies (MCNSAs) via an ambient-pressure chemical vapor deposition method was reported. And the resulting MCNSAs possess large surface areas, bimodal pore structures, abundant defective sites, excellent chemical stability, and sufficient magnetism.

Spatiotemporal variation of soil heavy metals in farmland influenced by human activities in the Poyang Lake region, China
Yefeng Jiang,Yingcong Ye,Xi Guo +2 more
TL;DR: In this article, the authors determined soil As, Cr, and Hg concentrations and characterized their spatiotemporal distributions in the Poyang Lake region using data from 85 and 208 sampling locations that were respectively obtained by the farmland environmental quality surveys conducted in 1983 and 2010.

Predictive quantitative structure–property relationship (QSPR) modeling for adsorption of organic pollutants by carbon nanotubes (CNTs)
TL;DR: In this article, the authors developed regression-based quantitative structure-property relationship (QSPR) models for organic pollutants and organic solvents using only easily computable 2D descriptors to explore the key structural features essential for adsorption to multi-walled CNTs and improve the dispersibility index of single-wall CNT.

Storage of hydrogen in single-walled carbon nanotubes
A. C. Dillon,Kim M. Jones,T. A. Bekkedahl,Ching-Hwa Kiang,Donald S. Bethune,Michael J. Heben +5 more
TL;DR: In this article, a gas can condense to high density inside narrow, single-walled nanotubes (SWNTs) under conditions that do not induce adsorption within a standard mesoporous activated carbon.

Stress-induced fragmentation of multiwall carbon nanotubes in a polymer matrix
TL;DR: In this article, the authors report the observation of single nanotube fragmentation, under tensile stresses, using nanotubes-containing thin polymeric films, and they estimate that the multi-wall multi-nanotube-matrix stress transfer efficiency is at least one order of magnitude larger than in conventional fiber-based composites.
