- Origin of Improved Optical Quality of Monolayer Molybdenum Disulfide Grown on Hexagonal Boron Nitride Substrate
Yi Wan, Hui Zhang, Wei Wang, Bowen Sheng, Kun Zhang, Yilun Wang, Qingjun Song, Nannan Mao, Yanping Li, Xinqiang Wang, Jin Zhang and Lun Dai

Monolayer MoS2 is synthesized on hexagonal boron nitride (h-BN) flakes with a simple, high-yield method. Monolayer MoS2 on h-BN exhibits improved optical quality. Combining the theoretical and experimental analysis, it is concluded that the enhanced photoluminescence and Raman intensities of monolayer MoS2 probably originate from the relatively weak doping effect from h-BN substrate rather than the optical interference effect.
- Long-Range Charge Transport in Adenine-Stacked RNA:DNA Hybrids

An extremely important biological component, RNA:DNA can also be used to design nanoscale structures such as molecular wires. The conductance of single adenine-stacked RNA:DNA hybrids is rapidly and reproducibly measured using the break junction approach. The conductance decreases slightly over a large range of molecular lengths, suggesting that RNA:DNA can be used as an oligonucleotide wire.
- Atomically Precise Prediction of 2D Self-Assembly of Weakly Bonded Nanostructures: STM Insight into Concentration-Dependent Architectures
Mohamed El Garah, Arezoo Dianat, Andrea Cadeddu, Rafael Gutierrez, Marco Cecchini, Timothy R. Cook, Artur Ciesielski, Peter J. Stang, Gianaurelio Cuniberti and Paolo Samorì

A concentration-dependent scanning tunneling microscopy investigation of the self-assembly of C3-symmetric molecule at a graphite/solution interface, collaborated with density functional theory calculations reveals the formation of four distinct supramolecular motifs.
- Black Phosphorus (BP) Nanodots for Potential Biomedical Applications

Black phosphorus (BP)-nanodots are prepared using a simple ultrasonication-assisted solution method. Compared to conventional semiconductor quantum dots, BP-nanodots present little in vitro cytotoxicity and further blue- and green-fluorescent bioimaging roles under excitations of UV and visible lights, showing potential as novel drug delivery carriers in biomedical applications.

Yang Hou, Shumao Cui, Zhenhai Wen, Xiaoru Guo, Xinliang Feng and Junhong Chen
Article first published online: 19 NOV 2015 | DOI: 10.1002/smll.201570267
A novel 3D hybrid electrocatalyst consisting of N-doped CoNi alloy-encapsulated carbon nanotubes (CoNi-NCNT)/N-doped porous carbon nanosheets (NPCNs) is obtained on page 5940 by X. L. Feng, J. H. Chen, and co-workers. The hybrid exhibits excellent electrocatalytic activities for the oxygen reduction and evolution reactions with good stability. The enhanced performance is correlated with the unique morphology and defect structures, high porosity, good conductive networks, and strongly interacting CoNi-NCNT and NPCNs.
