- Tuning Polymeric Amphiphilicity via Se–N Interactions: Towards One-Step Double Emulsion for Highly Selective Enzyme Mimics
Xiaopeng Huang, Ruochen Fang, Dingguan Wang, Jian Wang, Huaping Xu, Yapei Wang and Xi Zhang
Article first published online: 26 NOV 2014 | DOI: 10.1002/smll.201402271
A selenium-containing small molecule is exploited to controllably tune the polymer amphiphilicity, leading to fabrication of appropriate polymer surfactants through which one-step double emulsions can be obtained in a facile, scalable, surfactant-free approach. After solvent evaporation, these resulting porous microparticles are shown to be the exceptional artificial GPx enzyme mimics.
- Doping Modulated Carbon Nanotube Synapstors for a Spike Neuromorphic Module

A synapstor with a carbon nanotube (CNT) transistor structure is fabricated and integrated with a Si “soma” circuit to emulate the spike analog signal processing, memory, and plasticity of a neural network. The doping profile in the CNT channel is modulated to reduce its power consumption and establish postsynaptic current and plasticity in the synapstor.
- Surface Adhesive Forces: A Metric Describing the Drag-Reducing Effects of Superhydrophobic Coatings
Mengjiao Cheng, Mengmeng Song, Hongyu Dong and Feng Shi
Article first published online: 22 NOV 2014 | DOI: 10.1002/smll.201402618
Nanomaterials with superhydrophobic properties are promising as drag-reducing coatings. However, debates regarding whether superhydrophobic surfaces are favorable for drag reduction require further clarification. A quantified water adhesive force measurement is proposed as a metric and its effectiveness demonstrated using three typical superhydrophobic coatings on model ships with in situ sailing tests.
- High-Performance Hybrid Complementary Logic Inverter through Monolithic Integration of a MEMS Switch and an Oxide TFT
Yong-Ha Song, Sang-Joon Kenny Ahn, Min-Wu Kim, Jeong-Oen Lee, Chi-Sun Hwang, Jae-Eun Pi, Seung-Deok Ko, Kwang-Wook Choi, Sang-Hee Ko Park and Jun-Bo Yoon
Article first published online: 22 NOV 2014 | DOI: 10.1002/smll.201402841
A hybrid complementary logic inverter consisting of a microelectromechanical system switch as a promising alternative for the p-type oxide thin film transistor (TFT) and an n-type oxide TFT is presented for ultralow power integrated circuits. These heterogeneous microdevices are monolithically integrated. The resulting logic device shows a distinctive voltage transfer characteristic curve, very low static leakage, zero-short circuit current, and exceedingly high voltage gain.
- Superparamagnetic Iron Oxide Nanoparticle Micelles Stabilized by Recombinant Oleosin for Targeted Magnetic Resonance Imaging
Kevin B. Vargo, Ajlan Al Zaki, Robert Warden-Rothman, Andrew Tsourkas and Daniel A. Hammer
Article first published online: 22 NOV 2014 | DOI: 10.1002/smll.201402017
Recombinant surfactants present a new platform for stabilizing and targeting nanoparticle imaging agents. Superparamagnetic iron oxide nanoparticle-loaded micelles for MRI contrast are stabilized by an engineered variant of the naturally occurring protein oleosin and targeted using a Her2/neu affibody-oleosin fusion. The recombinant oleosin platform allows simple targeting and the ability to easily swap the ligand for numerous targets.
