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.

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

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.

An efficient photoelectrochemical cell for water splitting based on tetrapod-shaped CdS nanocrystals is reported by H. Zhang and co-workers on page 4727. The tetrapod-shaped CdS nanocrystals with tunable arm lengths and diameters are synthesized via a facile, phosphine-free, solution-based chemical method. Introducing tetrapod-shaped CdS nanocrystals with longer arm lengths provides less branch connection points/junctions, which probably trap and block the transportation of photoexcited electrons/holes, resulting in promising photocatalytic activity for water splitting in photoelectrochemical cells.
