The K+/18-crown-6-(or [2.2.2] cryptand)-stimulated formation and dissociation of G-quadruplex nanostructures lead to the cyclic and switchable photonic and electrocatalytic molecular devices.
- Towards Wafer-Scale Monocrystalline Graphene Growth and Characterization
Van Luan Nguyen and Young Hee Lee

Recent progress in chemical vapor deposition (CVD) graphene growth and characterization methods are reviewed in detail. This covers the efforts of single-nucleation and multi-nucleation approaches towards wafer-scale monocrystalline graphene without any grain boundaries. Moreover, the characterization methods of graphene grain boundaries and orientations from the atomic to the macro-scale are also addressed.
- Mechanistic Investigation of the Biological Effects of SiO2, TiO2, and ZnO Nanoparticles on Intestinal Cells

The toxicity of food-borne nanoparticles (NPs) is found to be governed by the physicochemical properties of the NPs and the genetic landscape of the cells. The different cellular responses of the various intestinal cell models may involve the production of reactive oxygen species (ROS). ZnO NPs are found to activate multiple pathways leading to a myriad of cellular responses, including cell-cycle arrest, inflammatory-gene activation, and cell death.
- One-Pot Synthesis of Tunable Crystalline Ni3S4@Amorphous MoS2 Core/Shell Nanospheres for High-Performance Supercapacitors
Yu Zhang, Wenping Sun, Xianhong Rui, Bing Li, Hui Teng Tan, Guilue Guo, Srinivasan Madhavi, Yun Zong and Qingyu Yan
Article first published online: 21 APR 2015 | DOI: 10.1002/smll.201403772
The nanoarchitechture of crystalline core/amorphous shell particles is proposed for enhanced capacitance and cyclability for supercapacitor electrodes. Driven by the concept, uniform transition metal sulfides core/amorphous shell nanospheres with tunable sizes are produced by a facile one-pot solution-based method. The resulting hybrids show great potential for supercapacitor applications.
