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.

Real-Time Label-Free Monitoring of Nanoparticle Cell Uptake

Real‐Time Label‐Free Monitoring of Nanoparticle Cell Uptake

Surface plasmon resonance in combination with HeLa cells is used to study cell uptake kinetics of several types of nanoparticles relevant to drug delivery applications. Mesoporous silica nanoparticles, branched polyethylenimine-plasmid DNA polyplexes, and red blood cell derived extracellular vesicles clearly show differences in the nature of the nanoparticle cell uptake depending on the type of nanoparticle under examination.

3D Quantification of Low‐Coordinate Surface Atom Density: Bridging Catalytic Activity to Concave Facets of Nanocatalysts in Fuel Cells

A protocol to quantify the distribution of surface atoms of concave nanocatalysts according to their coordination number is proposed. The 3D surface of an Au@Pd concave nanocube is reconstructed and segmented. The crystallographic coordinates and low-coordinate surface atom densities of the concave facets are determined. The result shows that 32% of the surface atoms are low-coordinated, which may contribute to the high activity.

Tracking the Fate of Surface Plasmon Resonance-Generated Hot Electrons by In Situ SERS Surveying of Catalyzed Reaction

Tracking the Fate of Surface Plasmon Resonance‐Generated Hot Electrons by In Situ SERS Surveying of Catalyzed Reaction

Just like a mirror, the footprint of surface plasmon resonance (SPR)-generated hot electrons is clearly imaged by SPR-enhanced vibrational spectroscopy. Being indicative to the multiple transferring processes and to the abundance of hot electrons (HEs), the p-nitirothiophenol to p-aminobenzenethiol reaction is capable of tracking the fate of HEs. This ultimately leads us to unravel the key factor that constrains the utilization of Ag as plasmonic catalyst.

Rh Dopants on Zn2GeO4 Surface as Active Sites for Photocatalytic Water Splitting

Doping has been widely used to engineer efficient photocatalysts for water splitting process in energy conversion and storage systems. Although composition tuning via heteroatom doping is one of the strategies to enhance photoactivity, the origin of the increasing activity by doping keeps unclear and the illustrations of its role most fall in the band engineering. Herein we report that the dopants rhodium on the surface of Zn2GeO4, which affect the band structure negligibly, can act as active sites for water splitting. As a result, the Rhδ+/Zn2GeO4 photocatalyst demonstrates excellent stability for 460 days and significant enhancement of the photocatalytic activity to that of the undoped photocatalyst. The findings in this work may open the door for a rethinking of the detailed principles of dopants in photocatalysis, and highlight a feasible route to fabricating efficient photocatalysts.

A New Look at the Electronic Structure of Transparent Conductive Oxides—A Case Study of the Interface between Zinc Magnesium Oxide and Cadmium Telluride

A novel approach to characterize the electronic structure of transparent conductive oxides, namely, to distinguish between optically and transport-relevant states is presented. Consequently, “optical” and “electronic” band offsets at the CdTe/(Zn,Mg)O interface are derived and it is demonstrated that the “electronic” band offset is suitable for electron transport across the interface (a flat conduction band alignment of 0.02 ± 0.20 eV), while the “optical band offset” is not (a significant 0.48 ± 0.20 eV spike).

Tailoring Photovoltage Response at SrRuO3/SrTiO3 Heterostructures

Tailoring Photovoltage Response at SrRuO3/SrTiO3 Heterostructures

The photovoltage and lifetime of the photo-excited carriers at the SrTiO3 surface drastically change with the SrRuO3 overlayers, as element specifically tracked by time-resolved core-level photoemission spectroscopy. The results show that the optical responses of oxide semiconductor heterostructures are designed by the band alignment scheme and they are tailored by the film growth.

Modern catalysis research is associated with a shift from largely empirical approaches towards the rational design of improved catalytic processes. An important contribution to this development is due to the rise of quantum chemical methods, which have enabled researchers to resolve reactions at the atomistic level and thus gain a deeper understanding of catalytic processes. This review will show selected examples of how quantum chemical studies have advanced our understanding of how organic molecules react over metal catalysts, which is of eminent importance for various industrial processes.

Tuning Colloidal Stability of Layered Double Hydroxides: From Monovalent Ions to Polyelectrolytes

Layered double hydroxide aggregation: Mono-, multi-, and polyvalent anions adsorb on layered double hydroxide (LDH) platelets to different extents, leading to different charging and aggregation behavior in aqueous suspensions. Simple monovalent salts destabilize LDHs by charge screening, polyelectrolytes by charge neutralization, whereas multivalent ions destabilize them by both effects. Highly stable LDH particles can be obtained by surface modification with polymeric compounds.
