Liquid li structure and dynamics: A comparison between OFDFT and second nearest‐neighbor embedded‐atom method

21.03.2015 | Mohan Chen, Joseph R. Vella, Frank H. Stillinger, Emily A. Carter, Athanassios Z. Panagiotopoulos, Pablo G. Debenedetti, AIChE Journal, 2015

Abstract The structure and dynamics of liquid lithium are studied using two simulation methods: orbital‐free first‐principles molecular dynamics, which employs orbital‐free density functional theory, and classical molecular dynamics utilizing a second nearest‐neighbor embedded‐atom method ...

Template-Free Electrochemical Synthesis of High Aspect Ratio Sn Nanowires in Ionic Liquids: A General Route to Large-Area Metal and Semimetal Nanowire Arrays?

20.03.2015 | Rihab Al-Salman; Heino Sommer; Torsten Brezesinski; Jürgen Janek, Chemistry of Materials, 2015

A facile low-temperature and template-free synthesis route to high aspect ratio Sn nanowires is described. The nanowires are prepared by electrochemical deposition from SnCl4/ionic liquid solutions containing SiCl4 onto a variety of substrates, including glassy carbon as well as Cu, Al, and Sn ...

IJMS, Vol. 16, Pages 6402-6418: Exploring the Nature of Silicon-Noble Gas Bonds in H3SiNgNSi and HSiNgNSi Compounds (Ng = Xe, Rn)

19.03.2015 | Pan, Sudip ; Saha, Ranajit ; Chattaraj, Pratim K., International Journal of Molecular Sciences, 2015

Ab initio and density functional theory-based computations are performed to investigate the structure and stability of H3SiNgNSi and HSiNgNSi compounds (Ng = Xe, Rn). They are thermochemically unstable with respect to the dissociation channel producing Ng and H3SiNSi or HSiNSi. However, they are ...

Nanotextured Pillars of Electrosprayed Bismuth Vanadate for Efficient Photoelectrochemical Water Splitting

17.03.2015 | Hyun Yoon; Mukund G. Mali; Jae Young Choi; Min-woo Kim; Sung Kyu Choi; Hyunwoong Park; Salem S. Al-Deyab; Mark T. Sw ..., Langmuir, 2015

We demonstrate, for the first time, electrostatically sprayed bismuth vanadate (BiVO4) thin films for photoelectrochemical water splitting. Characterization of these films by X-ray diffraction, Raman scattering, and high-resolution scanning electron microscopy analyses revealed the formation of ...

Understanding and tailoring the degradation of PVA‐tyramine hydrogels

16.03.2015 | Khoon S. Lim, Justine J. Roberts, Marie‐Helene Alves, Laura A. Poole‐Warren, Penny J. Martens, Journal of Applied Polymer Science, 2015

ABSTRACT We have previously reported on a hydrogel system fabricated from poly(vinyl alcohol) (PVA) functionalized with tyramine groups (PVA‐Tyr) that has the ability to co‐polymerize with proteins in their native state. These gels were also shown to be hydrolytically degradable through the ...

A Silicon-Based Two-Dimensional Chalcogenide: Growth of Si2Te3 Nanoribbons and Nanoplates

16.03.2015 | Sean Keuleyan; Mengjing Wang; Frank R. Chung; Jeffrey Commons; Kristie J. Koski, Nano Letters, 2015

We report the synthesis of high-quality single-crystal two-dimensional, layered nanostructures of silicon telluride, Si2Te3, in multiple morphologies controlled by substrate temperature and Te seeding. Morphologies include nanoribbons formed by VLS growth from Te droplets, vertical hexagonal ...

Enhanced O2 Selectivity versus N2 by Partial Metal Substitution in Cu-BTC

13.03.2015 | Dorina F. Sava Gallis; Marie V. Parkes; Jeffery A. Greathouse; Xiaoyi Zhang; Tina M. Nenoff, Chemistry of Materials, 2015

Here, we describe the homogeneous substitution of Mn, Fe, and Co at various levels into a prototypical metal–organic framework (MOF), namely Cu-BTC (HKUST-1), and the effect of that substitution on preferential gas sorption. Using a combination of density functional theory (DFT) calculations, ...

Oxidative Degradation of Decabromodiphenyl Ether (BDE 209) by Potassium Permanganate: Reaction Pathways, Kinetics, and Mechanisms Assisted by Density Functional Theory Calculations

13.03.2015 | Jiaqi Shi; Ruijuan Qu; Mingbao Feng; Xinghao Wang; Liansheng Wang; Shaogui Yang; Zunyao Wang, Environmental Science & Technology, 2015

This study found that decabromodiphenyl ether (BDE 209) could be oxidized effectively by potassium permanganate (KMnO4) in sulfuric acid medium. A total of 15 intermediate oxidative products were detected. The reaction pathways were proposed, which primarily included cleavage of the ether bond to ...
