The flexible architecture of a CoF2/carbon nanotube composite fabric is synthesized with remarkable combination of excellent mechanical properties, high electrochemical stability, and long-term lifespan as a conversion-type cathode for lithium ion batteries.
- Peptide-like Polymers Exerting Effective Glioma-Targeted siRNA Delivery and Release for Therapeutic Application

Peptide-like polymer/small interfering RNA (siRNA) complexes with disulfide bond crosslinking show a compact spherical appearance, a stable circulation in blood, and rapid siRNA release under high glutathione (GSH) concentration in glioma cells. For polyetherimide (PEI)/siRNA complexes, the compact spherical appearance is both stable in blood and glioma cells, which greatly decreases the release of siRNA for efficient therapeutic applications.

Article first published online: 28 JUL 2015 | DOI: 10.1002/smll.201501779
Using a conductive atomic force microscope (c-AFM) redox-writing technique, it is shown that it is possible to locally, and reversibly, pattern conducting, and nonconducting features on the surface of a low molecular weight aniline-based organic (semi)-conductor thin film using a commercial c-AFM. It is shown that application of a voltage between the tip and sample causes localized redox reactions at the surface without damage.
- An Aqueous Single Reactor Arc Discharge Process for the Synthesis of Graphene Nanospheres
Sejung Kim, Youngjun Song, Tsukasa Takahashi, Taeseok Oh and Michael J. Heller
Article first published online: 28 JUL 2015 | DOI: 10.1002/smll.201501022
Using an aqueous single reactor arc discharge process with oil-in-water emulsions allows production of 2D multilayered graphenes (MLGs and 3D graphene-based crumpled/sphere-like particles with low levels of defects). The confinement forces to create 3D particles from 2D MLGs are estimated to be 2.5 μN for crumpled particles and 70 μN for spherical hollow particles.
- Surface Conductive Graphene-Wrapped Micromotors Exhibiting Enhanced Motion

Surface-conductive Janus spherical motors are fabricated by wrapping silica particles with reduced graphene oxide capped with a thin Pt layer. These motors exhibit a 100% enhanced velocity as compared to standard SiO2–Pt motors. Furthermore, the versatility of graphene may open up possibilities for a diverse range of applications from active drug delivery systems to water remediation.
