  1. Simultaneous Nano- and Microscale Control of Nanofibrous Microspheres Self-Assembled from Star-Shaped Polymers

    Zhanpeng Zhang, Ryan L. Marson, Zhishen Ge, Sharon C. Glotzer and Peter X. Ma

    Article first published online: 26 MAY 2015 | DOI: 10.1002/adma.201501329

    Star-shaped polymers with varying arm numbers and arm lengths are synthesized, and self-assembled into microspheres, which are either smooth or fibrous on the nanoscale, and either nonhollow, hollow, or spongy on the microscale. The molecular architecture and functional groups determine the structure on both length scales. This exciting mechanistic discovery guides us to simultaneously control both nano- and microfeatures of the microspheres.

  2. From Soft Self-Healing Gels to Stiff Films in Suckerin-Based Materials Through Modulation of Crosslink Density and β-Sheet Content

    Dawei Ding, Paul A. Guerette, Jing Fu, Lihong Zhang, Scott A. Irvine and Ali Miserez

    Suckerins are block copolymer-like structural proteins constituting the building blocks of the strong squid sucker-ring teeth. Here, recombinant suckerin-19 is processed into biomaterials spanning a wide range of elasticity, from very soft hydrogels to stiff films with elastic modulus in the gigapascal range. The elasticity is controlled by the interplay between β-sheet content and induced di-tyrosine crosslinking.

  3. Guided Growth of Horizontal ZnSe Nanowires and their Integration into High-Performance Blue–UV Photodetectors

    Eitan Oksenberg, Ronit Popovitz-Biro, Katya Rechav and Ernesto Joselevich

    Article first published online: 26 MAY 2015 | DOI: 10.1002/adma.201500736

    Perfectly aligned horizontal ZnSe nano­wires are obtained by guided growth, and easily integrated into high-performance blue–UV photodetectors. Their crystal phase and crystallographic orientation are controlled by the epitaxial relations with six different sapphire planes. Guided growth paves the way for the large-scale integration of nanowires into optoelectronic devices.

  4. Fabrication of Nanoscale Circuits on Inkjet-Printing Patterned Substrates

    Shuoran Chen, Meng Su, Cong Zhang, Meng Gao, Bin Bao, Qiang Yang, Bin Su and Yanlin Song

    Article first published online: 26 MAY 2015 | DOI: 10.1002/adma.201500225

    Nanoscale circuits are fabricated by assembling different conducting materials (e.g., metal nanoparticles, metal nano­wires, graphene, carbon nanotubes, and conducting polymers) on inkjet-printing patterned substrates. This nonlitho­graphy strategy opens a new avenue for integrating conducting building blocks into nanoscale devices in a cost-efficient manner.

  5. The First Organic–Inorganic Hybrid Luminescent Multiferroic: (Pyrrolidinium)MnBr3

    Yi Zhang, Wei-Qiang Liao, Da-Wei Fu, Heng-Yun Ye, Cai-Ming Liu, Zhong-Ning Chen and Ren-Gen Xiong

    Article first published online: 26 MAY 2015 | DOI: 10.1002/adma.201501026

    A hybrid organic–inorganic compound, (pyrrolidinium)MnBr3, distinguished from rare earth (RE)-doped inorganic peroveskites, is discovered as a new member of the ferroelectrics family, having excellent luminescent properties and relatively large spontaneous polarization of 6 μC cm−2, as well as a weak ferromagnetism at about 2.4 K. With a quantum yield of >28% and emission lifetime >0.1 ms, such multiferroic photoluminescence is a suitable candidate for future applications in luminescence materials, photovoltaics, and magneto-optoelectronic devices.
