Surfaces and Interfaces

Self-ordered surface wrinkling patternsInterfaces and surfaces are where the action happens. Catalysis, molecular recognition, charge transfer, polymerization and many other critical processes take place at the boundary between one medium and another. With the need to integrate new materials into devices, and applications ranging from catalysis to sensors, medicine to self-cleaning surfaces, and displays to lasers, fundamental and applied studies of surface and interface processes and optimization are of critical importance in developing new technology to meet today's challenges. The selection of recent research articles presented below illustrates the vast potential of this field.

Surface-Induced Selection During In Situ Photoswitching at the Solid/Liquid Interface

A diarylethene derivative exhibits pronounced affinity for the graphite surface in all its isomeric forms. The photoswitch between its two isomers, that is, the open and closed form, at the solid/liquid interface is investigated by submolecularly resolved scanning tunneling microscopy and atomistic modeling. Prolonged irradiation leads to the in situ irreversible formation of another isomer as by-product of the reaction.

Ion-Specific Oil Repellency of Polyelectrolyte Multilayers in Water: Molecular Insights into the Hydrophilicity of Charged Surfaces

Wet surfaces: Liquid wetting on charged surfaces is well correlated with the molecular nature of surface ionic groups. The orientation change of surface ionic groups either hardly affects water wetting if their configuration is isotropic, or markedly transforms poor water wetting in oil to poor water de-wetting in water if their configuration is anisotropic, thus leading to excellent underwater oil repellency.

Control of the Intermolecular Coupling of Dibromotetracene on Cu(110) by the Sequential Activation of C-Br and C-H Bonds [Full Paper]

Control of the Intermolecular Coupling of Dibromotetracene on Cu(110) by the Sequential Activation of C-Br and C-H Bonds

Scratching the surface: Easy control of the intermolecular coupling of 5,11-dibromotetracene on a Cu(110) surface by temperature has been achieved. Organometallic oligomers characterized by copper atoms that bridge the tetracene molecule in the 5,11 positions are formed at mild temperature (room temperature to 523 K), whereas the higher intrinsic stability of the radical sites at the 3,2 and 8,9 positions determines the formation of linear chains produced by C-C coupling between the ends of the molecules at higher temperature (see picture).

Design and Synthesis of Biotin Analogues Reversibly Binding with Streptavidin

Forming a bond: Two new biotin analogues, biotin carbonate and biotin carbamate, have been designed and synthesized. Surface plasmon analysis of the water-soluble analogues of these compounds revealed that the KD value of biotin carbonate analogue was 6.7×10−6 M and 1.7×10−10 M for the biotin carbamate analogue. These two analogues might be useful owing to their ability to reversibly interact with streptavidin.

Control of Solid Catalysts Down to the Atomic Scale: Where is the Limit?

Down to the last detail: Nanostructured solid catalysts were already known in the early 20th century, but their exact structure was unclear. Nowadays, the arrangement of atoms and particles in solids can be manipulated and analyzed down to the atomic scale (see image). The use of specific highly active catalysts enables industrially relevant reactions to be performed at room temperature.

Ultrathin Silica Films: The Atomic Structure of Two-Dimensional Crystals and Glasses [Minireview]

Ultrathin Silica Films: The Atomic Structure of Two-Dimensional Crystals and Glasses

Polishing up the crystal glasses: An overview of the preparation and characterization of ordered silica films on metal supports is reported. In particular, the specific case of a silica bilayer, which exists in a crystalline and a vitreous variety, is discussed and a model of the vitreous silica structure proposed by William Zachariasen in 1932 is verified. Beyond this, the possibility to prepare the crystalline and the glassy structure on the same support leads to the study of the crystal–glass phase transition in real space (see figure).

Interphase Evolution at Two Promising Electrode Materials for Li-Ion Batteries: LiFePO4 and LiNi1/2Mn1/2O2 [Review]

Interphase Evolution at Two Promising Electrode Materials for Li-Ion Batteries: LiFePO4 and LiNi1/2Mn1/2O2

The importance of the chemical history of the electrode surface before electrochemical cycling as well as the correlation between interface phenomena, the formation/evolution of an interphase, and the electrochemical behavior of LiFePO4 and LiNi1/2Mn1/2O2 electrodes are investigated by magic-angle-spinning nuclear magnetic resonance, electron energy loss spectroscopy, and X-ray photoelectron spectroscopy. These techniques allow the study of interface aging and failure mechanisms.

Covalent Surface Modification of Oxide Surfaces [Review]

Covalent Surface Modification of Oxide Surfaces

Not just scratching the surface: Covalently attached monolayers on oxide surfaces are reviewed with an eye to improved robustness, increased functionalization, understanding structural details, and the resulting potential for applications. Such monolayers, provided they are robust enough, provide a way of improving the properties of the bulk oxide material.

Surface-Enhanced Raman Spectroscopy: Concepts and Chemical Applications

Expanding vibrational spectroscopy: Since its first observation in 1973, surface-enhanced Raman scattering (SERS) has developed into a mature vibrational spectroscopic technique. The number of applications in chemistry as well as the material and life sciences is increasing rapidly. This Review summarizes the key concepts behind SERS and provides an overview of current applications in chemistry.

Logic Functions with Stimuli-Responsive Single Nanopores

Porefection: Electrochemical transducers based on single stimuli-responsive polymeric nanopores can support a complete set of logic functions. Thermal, chemical, electrical, and optical stimuli are the input signals required to externally tune the pore conductance (i.e. the logical output).

Atomic and Electronic Structures of Interfaces in Dye-Sensitized, Nanostructured Solar Cells

Core of the matter: Key processes in nanostructured dye-sensitized solar cells (DSC) occur at material interfaces containing, for example, oxides, dye molecules, and hole conductors (see picture). The implementation of X-ray-based spectroscopic methods for atomic-level understanding of such properties is reviewed. Examples include energy matching, binding configurations, and molecular orbital composition.

Electrochemistry of Nanoparticles

Revealing electrochemistry: Key issues related to the electrochemistry of nanoparticles are being uncovered through innovative techniques capable of relating activity and structure, ultimately at the level of a single nanoparticle. Recent advances in experimental approaches are discussed and assessed, with particular emphasis on those that enhance the fundamental understanding of electrocatalysis and nanoscale electrochemistry.

Effective Surface Functionalization of Carbon Fibers for Fiber/Polymer Composites with Tailor-Made Interfaces

High in fiber: Carbon fibers (CFs), which are widely utilized in fields ranging from fundamental research to industry, can be functionalized by both thin-layer coating and nanoparticle immobilization (see scheme). In this Minireview, these techniques and some practical applications of functionalized CFs, such as carbon fiber reinforced plastic (CFRP), are overviewed after briefly describing the basic properties of CFs.
