Hierarchically CdS Decorated 1D ZnO Nanorods‐2D Graphene Hybrids: Low Temperature Synthesis and Enhanced Photocatalytic Performance

13.10.2014 | Chuang Han, Zhang Chen, Nan Zhang, Juan Carlos Colmenares, Yi‐Jun Xu, Advanced Functional Materials, 2014

A simple, low‐temperature synthesis approach is reported for planting CdS‐sensitized 1D ZnO nanorod arrays on the 2D graphene (GR) sheet to obtain the ternary hierarchical nanostructures, during which graphene oxide (GO) as the precursor of GR acts as a flexible substrate for the formation of ...

Narrow Bandgap in β-BaZn2As2 and Its Chemical Origins

10.10.2014 | Zewen Xiao; Hidenori Hiramatsu; Shigenori Ueda; Yoshitake Toda; Fan-Yong Ran; Jiangang Guo; Hechang Lei; Satoru Mats ..., Journal of the American Chemical Society, 2014

β-BaZn2As2 is known to be a p-type semiconductor with the layered crystal structure similar to that of LaZnAsO, leading to the expectation that β-BaZn2As2 and LaZnAsO have similar bandgaps; however, the bandgap of β-BaZn2As2 (previously reported value ∼0.2 eV) is 1 order of magnitude smaller than ...

On the scaling behavior of electric conductivity in [C4mim][NTf2]

09.10.2014 | Z. Wojnarowska; G. Jarosz; A. Grzybowski; J. Pionteck; J. Jacquemin; M. Paluch, Physical Chemistry Chemical Physics, 2014

In this work we examine, for the first time, the molar conductivity behavior of the deeply supercooled room temperature ionic liquid [C4mim][NTf2] in the temperature, pressure and volume thermodynamic space in terms of density scaling (TVγ)−1 combined with the equation of state (EOS). The ...

Li-rich anti-perovskite Li3OCl films with enhanced ionic conductivity

08.10.2014 | Xujie Lü; Gang Wu; John W. Howard; Aiping Chen; Yusheng Zhao; Luke L. Daemen; Quanxi Jia, Chemical Communication, 2014

Anti-perovskite solid electrolyte films were prepared by pulsed laser deposition, and their room-temperature ionic conductivity can be improved by more than an order of magnitude in comparison with its bulk counterpart. The cyclability of Li3OCl films in contact with lithium was evaluated using a ...

Nanostructure–Thermal Conductivity Relationships in Protic Ionic Liquids

07.10.2014 | Thomas Murphy; Luis M. Varela; Grant B. Webber; Gregory G. Warr; Rob Atkin, Journal of Physical Chemistry B, 2014

The thermal conductivities of nine protic ionic liquids (ILs) have been investigated between 293 and 340 K. Within this range, the thermal conductivities are between 0.18 and 0.30 W·m–1·K–1. These values are higher than those typically associated with oils and aprotic ILs, but lower than those of ...
