Stick, twist, or fold?
In the Concepts section, M. Cargnello et al. explain how catalysts with improved activity, stability, and selectivity can be prepared by manipulating clusters and nanocrystals as building blocks. Y. Zhao describes the use of cooperatively enhanced receptors for biomimetic molecular recognition. In an Essay, V. S. Pervov and A. E. Zotova discuss some of the problems of inorganic supramolecular chemistry. Finally, the Article by A. H. Duarte Lopez, G. F. Caramori, et al. deals with the applicability of systems connected through multiple hydrogen bonds in the design of new materials.

Beyond graphene: A novel and bifunctional 3D composite hydrogel containing reduced graphene-oxide nanosheets and V2O5 nanobelts is presented. This bifunctional material exhibits excellent properties as electromagnetic wave absorbent and can also be used as a supercapacitor for a two-electrode system delivering a high specific capacitance of about 320 F g−1.

Single molecules on the move: Two fitting functions are introduced for measuring in-frame motion of isolated fluorescent emitters. These methods determine the instantaneous directionality and velocity of motion without sacrificing the localization precision. Theory, simulation, and experiments are used to validate the methods, and the fitting algorithms are applied to the motion of live bacteria cells (see picture).

Screening factor: Interionic interactions in a metallic nanopore are exponentially screened by electrons of the metal, with the screening length proportional to the pore width or diameter. This article investigates how such screening would look in non-ideally metallic electrodes, typical for semi-metallic carbons.

Pore-fect! Structurally stabilized mesoporous anatase titania is prepared by using a novel organosilane template that is uniquely decorated with isolated SiO2 sites. Exceptional thermal stability and the highest surface area known for this material are achieved. The inorganic Si portion of the template is found to be incorporated in the pore walls of titania aggregates, mainly decorating them as isolated sites.
- Increasing the Brightness of Cyanine Fluorophores for Single-Molecule and Superresolution Imaging

The fluorescence quantum yield and lifetime of red-emitting cyanine dyes can be substantially increased in heavy water (D2O) compared with water (H2O), scaling with the emission wavelength of the fluorophores and correlating with the vibrational absorption spectrum of water. This finding is beneficial for single-molecule and superresolution microscopy.
