Controlled Synthesis and Multifunctional Properties of FePt–Au Heterostructures

Jiajia Wu, Yanglong Hou, Song Gao

In this work, FePt–Au heterostructured nanocrystals (HNCs) such as tadpole-, dumbbell-, bead-, and necklace-like nanostructures were synthesized by a facile heteroepitaxial growth of Au NCs onto FePt nanorods (NRs). A study of the growth mechanism revealed that the morphology control of the final products can be correlated with the adsorption sites of hydrogen onto the FePt NRs, which can be manipulated by the amount of the forming gas (Ar/7% H2) added. Not only the optical characteristic and magnetic properties of the intrinsic materials were retained in the products, but also the FePt–Au HNCs showed the tunable multifunctional properties resulted from the interactions between Au and FePt. Moreover, for methanol oxidation, the FePt–Au HNCs exhibited enhanced catalytic activity and CO tolerance on the catalyst surface compared to commercial Pt catalysts. It is worth noting that as multifunctional units, the FePt–Au HNCs also possess a heterogeneous surface, which could potentially enable their site-specific functionalization for targeting or imaging purposes in biomedical applications. More interestingly, the catalytic properties of the FePt–Au HNCs also endow this material with application potentials in nanocatalysis.

Nanoscale Topography: Aptamer-Mediated Efficient Capture and Release of T Lymphocytes on Nanostructured Surfaces

Li Chen, Xueli Liu, Bin Su, Jing Li, Lei Jiang, Dong Han and Shutao Wang

Easy capture and easy release! The cover illustrates a nanostructured platform that combines silicon nanowire arrays and targeted DNA aptamers, realizing significant capture and efficient release of T lymphocytes. This method of capture and release provides an artful strategy to fulfill the demands of cell isolation and diagnostics, as reported by Dong Han, Shutao Wang, and co-workers on page 4376.

Preparation of Highly Stable and Water-Dispersible Silicon Quantum Dots by Using an Organic Peroxide

Dr. Jiechao Ge, Dr. Weimin Liu, Wenwen Zhao, Dr. Hongyan Zhang, Dr. Xiaoqing Zhuang, Minhuan Lan, Dr. Prof. Pengfei Wang, Hongqiang Li, Dr. Prof. Guangzhao Ran and Dr. Prof. Shuit-Tong Lee

A new method of preparing water-dispersible silicon quantum dots (QDs, blue spheres) has been developed by using an organic peroxide as a highly effective precursor (the lower left quarter, red and grey–green ball-and-stick model). The obtained water-dispersible carboxylic acid terminated Si QDs displayed strong and stable photoluminescence in the visible spectrum, which can be widely used in boimedical imaging. For more detail, see the Communication by S.-T. Lee, P.-F. Wang et al. on page 12872 ff.

Functional Thin Films: Controllable Underwater Oil-Adhesion-Interface Films Assembled from Nonspherical Particles

Yu Huang, Mingjie Liu, Jingxia Wang, Jinming Zhou, Libin Wang, Yanlin Song and Lei Jiang

The cover shows controllable underwater oil-adhesion films assembled from nonspherical latex particles. On page 4436, Jingxia Wang, Yanlin Song, and co-workers show how the underwater oil adhesion force of films could be effectively controlled from high adhesion to low adhesion when the films are assembled from latex particles of spherical, cauliflower-like and single-cavity structure, respectively. This offers significant insight for the design and creation of novel underwater anti-fouling materials.

Electron transporting semiconducting polymers in organic electronics

Xingang Zhao and Xiaowei Zhan

Significant progress has been achieved in the preparation of semiconducting polymers over the past two decades, and successful commercial devices based on them are slowly beginning to enter the market. However, most of the conjugated polymers are hole transporting, or p-type, semiconductors that have seen a dramatic rise in performance over the last decade. Much less attention has been devoted to electron transporting, or n-type, materials that have lagged behind their p-type counterparts. Organic electron transporting materials are essential for the fabrication of organic p–n junctions, organic photovoltaic cells (OPVs), n-channel organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs) and complementary logic circuits. In this critical review we focus upon recent developments in several classes of electron transporting semiconducting polymers used in OLEDs, OFETs and OPVs, and survey and analyze what is currently known concerning electron transporting semiconductor architecture, electronic structure, and device performance relationships (87 references).

Flexible Electronics: Sub-Micrometer-Thick All-Solid-State Supercapacitors with High Power and Energy Densities

Fanhui Meng and Yi Ding

Flexible, all-solid-state supercapacitors with sub-micrometer thickness are reported by Yi Ding and co-workers on page 4098. This power source, which is based on a unique nanoporous gold/polypyrrole (NPG-PPy) hybrid nanostructure, demonstrates high volumetric capacitance as well as high power and energy densities, suggesting its potential in powering next-generation wearable and miniaturized electronic devices.
