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.

Efficient, Hysteresis‐Free, and Stable Perovskite Solar Cells with ZnO as Electron‐Transport Layer: Effect of Surface Passivation

Surface passivation of ZnO by a thin layer of MgO and protonated ethanolamine readily makes ZnO a very promising electron-transporting material for creating efficient, hysteresis-free and stable perovskite solar cells (PSCs). PSCs, stable in air for more than 300 h, are achieved when graphene is used to encapsulate the cells.

Anisotropic Ag2S–Au Triangular Nanoprisms with Desired Configuration for Plasmonic Photocatalytic Hydrogen Generation in Visible/Near-Infrared Region

Anisotropic Ag2S–Au Triangular Nanoprisms with Desired Configuration for Plasmonic Photocatalytic Hydrogen Generation in Visible/Near‐Infrared Region

Anisotropic Ag2S-edged Au-triangular nanoprisms (TNPs), exhibiting almost four-fold higher efficiency than Ag2S-covered ones in hydrogen generation under visible-NIR light irradiation, are synthesized by controlling preferential overgrowth of Ag2S. Single-particle photoluminescence and finite-difference-time-domain studies demonstrate that Ag2S-edged Au-TNPs have the desired configuration for plasmon-induced hot electron transfer and charge separation, leading to highly efficient hydrogen generation.

Pd‐Tipped Au Nanorods for Plasmon‐Enhanced Electrocatalytic Hydrogen Evolution with Photoelectric and Photothermal Effects

Tip of the iceberg: Pd-tipped Au nanorods (NRs) are prepared in the presence of CTAB and 5-BrSA for the electrocatalytic hydrogen evolution reaction in the visible and near-infrared region. The tipped NRs exhibit a lower onset overpotential (40 mV) and higher exchange current density (1.585 mA/cm2) than fully covered ones, which is ascribed to synergetic photothermal and photoelectric effects.

21st Century Advances in Fluorescence Techniques to Characterize Glass‐Forming Polymers at the Nanoscale

Fluorescence techniques present unique capabilities for characterization of glass-forming polymers at the nanoscale. Advances in fluorescence over the past two decades have provided insight into the behavior of the glass transition temperature, physical aging, diffusion and mobility, and mechanical response in polymers confined to nanometer dimensions through sensitive, location-specific measurements.

Organic−Inorganic-Hybrid-Derived Molybdenum Carbide Nanoladders: Impacts of Surface Oxidation for Hydrogen Evolution Reaction

Organic−Inorganic‐Hybrid‐Derived Molybdenum Carbide Nanoladders: Impacts of Surface Oxidation for Hydrogen Evolution Reaction

Moderate surface oxygen can efficiently promote the HER activity of molybdenum carbide nanoladders via a good balance of Volmer and Heyrovsky/Tafel steps in kinetics, which should be ascribed to the downshift of d-band center of Mo atoms and the introduced steric hindrance from surface oxygen atoms.

Laccase-Mediated Grafting on Biopolymers and Synthetic Polymers: A Critical Review

Laccase‐Mediated Grafting on Biopolymers and Synthetic Polymers: A Critical Review

To graft or not to graft? Laccase-mediated grafting is a simple and mild approach to covalently modify surfaces and thereby generate (bio)functionalised materials. However, differentiation between adsorption and grafting is not always straightforward and can be easily overlooked.

Functional and Switchable Amphiphilic PMMA Surface Prepared by 3D Selective Modification

Functional and Switchable Amphiphilic PMMA Surface Prepared by 3D Selective Modification

The design and realization of 3D spatially selective modified poly(methylmethacrylate) surface with switchable amphiphilicity are described. The smart amphiphilic response is achieved through the in-plane and height distinguished grafting of highly hydrophobic 3,5- bis(trifluoromethyl)phenyl groups and temperature controlled hydrophilic/phobic poly(N-isopropylacrylamide) chains.

Liquid Shaping Based on Liquid Pancakes

Liquid Shaping Based on Liquid Pancakes

Water in milliliter order forms a pancake shape on a superhydrophobic surface. Subjecting such a pancake to interfacial jamming of nanoparticles allows a segmenting manipulation of the coated liquid pancake. Based on this mechanism, liquid shaping is realized with the resulting product, as liquid plasticine, characterized with accurate profile, large size, and high transparency.

X-ray Radiography to Visualize the Rebar–Cementitious Matrix Interface and Judge the Delay in Corrosion through Self-Repair by Encapsulated Polyurethane

X‐ray Radiography to Visualize the Rebar–Cementitious Matrix Interface and Judge the Delay in Corrosion through Self‐Repair by Encapsulated Polyurethane

The efficiency of autonomous crack healing to delay corrosion is shown for both orthogonally and longitudinally oriented cracks. A mechanically triggered self-healing approach is used and the efficiency is compared against manual crack healing. Next to a visual analysis, X-ray radiography is used to study the evolution of the rebar–cementitious matrix interface due to corrosion.

Nanoarchitectonics from Molecular Units to Living-Creature-Like Motifs

Nanoarchitectonics from Molecular Units to Living‐Creature‐Like Motifs

Recently, a new conceptual paradigm, nanoarchitectonics, has been proposed to combine nanotechnology and other methodologies including supramolecular chemistry, self-assembly and self-organization to satisfy major features of nanoscience and promote the creation of functional materials and systems. In this account article, our recent research results on materials development based on the nanoarchitectonics concept are summarized.

A Combined Electrochemical-Microfluidic Strategy for the Microscale-Sized Selective Modification of Transparent Conductive Oxides

A Combined Electrochemical‐Microfluidic Strategy for the Microscale‐Sized Selective Modification of Transparent Conductive Oxides

An electrochemical-microfluidic combined methodology to modify transparent conductive oxides (TCOs) is proposed. The production of complex molecular structures, selectively localized in the microscale-sized areas where electrochemical grafting has taken place is demonstrated by realizing an electrochemical biosensor through a layer-by-layer approach. This strategy offers a method to produce customizable TCOs for different applications requiring defined patterning.

Local Glass Transition Temperature Tg(z) Profile in Polystyrene next to Polybutadiene with and without Plasticization Effects

Local Glass Transition Temperature Tg(z) Profile in Polystyrene next to Polybutadiene with and without Plasticization Effects

Local glass transition temperature Tg(z) profile of glassy polystyrene (PS) next to rubbery polybutadiene (PB) is compared with and without a small-molecule additive in PB migrating to the PS domain causing plasticization. It is also demonstrated that the broad and asymmetric experimentally observed Tg(z) profiles are not caused by the migration of low molecular weight chains across the interface.

Stimuli-Responsive Cucurbit[n]uril-Mediated Host-Guest Complexes on Surfaces

Stimuli‐Responsive Cucurbit[n]uril‐Mediated Host‐Guest Complexes on Surfaces

In this review we highlight the latest progress of CB[n]-mediated host-guest complexes on surface with special attention to stimuli-responsive studies. Stimulus-responsive systems by pH, light or electrochemistry are attractive as such systems offer advantages such as dynamicity and reversibility, so that they are able to function as molecular machines or mimic molecular systems from nature.

Smart Amphiphilic Janus Microparticles: One-Step Synthesis and Self-Assembly

Smart Amphiphilic Janus Microparticles: One‐Step Synthesis and Self‐Assembly

How size influences behavior: Sub-millimeter-sized amphiphilic Janus microparticles are found to self-assemble into clusters whose structures are similar to those made of nanoparticles. The amphiphilic Janus microparticles orient between the water–oil interface to form micelle-like structures. When the water evaporates, the particles aggregate into orderly superstructures.
