Fullerene-Assisted Photoinduced Charge Transfer of Single-Walled Carbon Nanotubes through a Flavin Helix

29-Apr-2016 | Mehdi Mollahosseini; Erandika Karunaratne; George N. Gibson; Jose A. Gascón; Fotios Papadimitrakopoulos, Journal of the American Chemical Society, 2016

One of the greatest challenges with single-walled carbon nanotube (SWNT) photovoltaics and nanostructured devices is maintaining the nanotubes in their pristine state (i.e., devoid of aggregation and inhomogeneous doping) so that their unique spectroscopic and transport characteristics are ...

C‐chain doping‐induced band‐states transition in armchair AlN nanoribbon

28-Apr-2016 | Lijia Tong, Zheng Chen, Hongxiang Zong, Luting Huang, Ruimin Bai, Jing Zhang, physica status solidi (b), 2016

Little is known about the band states of armchair AlN nanoribbons (aAlNNRs), so we investigated their band states of perfect and single C‐chain‐doped aAlNNRs by first‐principles calculations. For aAlNNRs with a width N 8) was mainly studied. In contrast to a h‐AlN monolayer, we find a second ...

Ultrafast Nanoimaging of the Photoinduced Phase Transition Dynamics in VO2

28-Apr-2016 | Sven A. Dönges; Omar Khatib; Brian T. O’Callahan; Joanna M. Atkin; Jae Hyung Park; David Cobden; Markus B. Raschke, Nano Letters, 2016

Many phase transitions in correlated matter exhibit spatial inhomogeneities with expected yet unexplored effects on the associated ultrafast dynamics. Here we demonstrate the combination of ultrafast nondegenerate pump–probe spectroscopy with far from equilibrium excitation, and scattering ...

Exceptionally water stable heterometallic gyroidal MOFs: tuning the porosity and hydrophobicity by doping metal ions

26-Apr-2016 | Xiao-Wei Zhu; Xiao-Ping Zhou; Dan Li, Chemical Communication, 2016

A strategy to improve the framework porosity and hydrophobicity of the pore surface by doping metal ions (Cu2+, Cd2+, or Fe2+) into a gyroidal MOF STU-1 has been developed. It is found that the obtained heterometallic MOFs are exceptionally water stable.

Computational Prediction of High Thermoelectric Performance in Hole Doped Layered GeSe

26-Apr-2016 | Shiqiang Hao; Fengyuan Shi; Vinayak P. Dravid; Mercouri G. Kanatzidis; Christopher Wolverton, Chemistry of Materials, 2016

Thermoelectric materials enable direct conversion between thermal and electrical energy and provide a viable route for power generation and electric refrigeration. In this paper, we use first-principles based methods to predict a very high figure of merit (ZT) performance in hole doped GeSe ...

Fabrication of 3 D Mesoporous Black TiO2/MoS2/TiO2 Nanosheets for Visible‐Light‐Driven Photocatalysis

25-Apr-2016 | Xuefeng Liu, Zipeng Xing, Hang Zhang, Wenmei Wang, Yan Zhang, Zhenzi Li, Xiaoyan Wu, Xiujuan Yu, Wei Zhou, ChemSusChem, 2016

Abstract A novel 3 D mesoporous black TiO2 (MBT)/MoS2/MBT sandwich‐like nanosheet was successfully fabricated using a facile mechanochemical process combined with an in situ solid‐state chemical reduction approach, followed by mild calcination (350 °C) under an argon atmosphere. The ...

Simple Salt‐Coordinated n‐Type Nanocarbon Materials Stable in Air

25-Apr-2016 | Yoshiyuki Nonoguchi, Motohiro Nakano, Tomoko Murayama, Harutoshi Hagino, Shota Hama, Koji Miyazaki, Ryosuke Matsubar ..., Advanced Functional Materials, 2016

After more than three decades of molecular and carbon‐based electronics, the creation of air‐ and thermally stable n‐type materials remains a challenge in the development of future p/n junction devices such as solar cells and thermoelectric modules. Here a series of ordinary salts are reported ...

Graphene as a Tunable Anisotropic or Isotropic Plasmonic Metasurface

25-Apr-2016 | Paloma A. Huidobro; Matthias Kraft; Stefan A. Maier; John B. Pendry, ACS Nano, 2016

We demonstrate a tunable plasmonic metasurface by considering a graphene sheet subject to a periodically patterned doping level. The unique optical properties of graphene result in electrically tunable plasmons that allow for extreme confinement of electromagnetic energy in the technologically ...

A Systematic Study of the Effects of Metal Chloride Additives on H2 Desorption Properties of Ammonia Borane

22-Apr-2016 | Yuki Nakagawa; Tengfei Zhang; Masaumi Kitamura; Shigehito Isobe; Satoshi Hino; Naoyuki Hashimoto; Somei Ohnuki, Journal of Chemical & Engineering Data, 2016

The effects of metal-based additives in a wide range of elements doping into ammonia borane (AB) were systematically investigated. Pure transition metals in period 4 and total of 17 metal chlorides were selected as additives and ball-milled with AB. Metal chloride additives were effective to ...
