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.

Cd(II) Pseudohalide Complexes with N, N′‐Bis(3‐ethoxysalicylidenimino) 1,3‐Diaminopropane: Crystal Structures, Hirshfeld Surface, Antibacterial and Anti‐Biofilm Properties

Three novel Cd(II) complexes [Cd2LOEt(μ1,3-SCN)(η1-SCN)]n (1), [Cd4(LOEt)2(μ1,1-N3)3(η1-N3)]2 (2) and [Cd2(LOEt)(Cl)2.CH3OH].CH3OH(3) have been synthesized in presence of pseudohalides (SCN/N3) or Cl as spacer and Schiff base ligand (H2LOEt) via self-assembly process. Ligand based luminescent properties of these complexes have been studied in DMSO solution at room temperature. Intermolecular interactions with respect to percentages of hydrogen bonding of cadmium (II) complexes 1–3 were quantified by Hirshfeld surface and fingerprint plots. Antibacterial and antibiofilm properties were investigated which is a potent inhibitor against both Gram-positive and Gram-negative bacterial strains.

Exceptionally High Performance Anode Material Based on Lattice Structure Decorated Double Perovskite Sr2FeMo2/3Mg1/3O6−δ for Solid Oxide Fuel Cells

Double perovskite Sr2FeMo2/3Mg1/3O6−δ shows very interesting structural/catalytic properties, excellent redox stability and high electrochemical performance. These excellent properties are related to the discovered anti-site defects, which is triggered by Mg doping for Mo and created by the occupancy of Fe at both B and B′-sites. The anti-site defects are found to be beneficial to ionic conductivity and electrochemical catalytic activity.

Let it rain: The dependence of stability and activity of Ni2P/SiO2 hydrodeoxygenation (HDO) catalysts on the support surface polarity is addressed in detail. The correlation between catalyst performance and support surface polarity indicates that, to prevent deactivation of the catalyst by water under reaction conditions, the affinity of the support towards polar substances must be decreased below a certain threshold value.

Surface Chemistry of All Inorganic Halide Perovskite Nanocrystals: Passivation Mechanism and Stability

The instability of CsPbBr3 nanocrystals (NCs) is attributed to not only the internal crystal structure feature but also to the external factors including the illumination, humidity, oxygen, and UV, which lead to the degradation and photoluminescence (PL) loss of CsPbBr3 NCs. Therefore, surface passivation plays a crucial role in the improvement of PL quantum yield, stability, and device performance.

Electrochemical characterization shows that alkylphosphonate layer choice impacts electrochemical behavior, a consequence of the affinity of the SAM with the battery electrolyte. Computational studies report on SAM-electrolyte and SAM-cathode stability. Lithium-ion half cells constructed with SAM modified cathodes show that surface modification leads to reduction in capacity fade.

Designing Nanoparticles and Nanoalloys with Controlled Surface and Reactivity

Designing Nanoparticles and Nanoalloys with Controlled Surface and Reactivity

Nanoalloys are a playground to establish structure-properties relationships within the nano-matter. Rational design of the synthesis parameters (oxidation state of precursors, reaction temperature, stoichiometry) gives unique access to nanoparticles with well-defined surface. Reactivity of nanoparticles under environmental conditions is investigated. In situ microscopy, near-ambient-pressure x-ray photoelectron spectroscopy and soft x-ray absorption spectroscopy highlight complex transformation of the nanoparticles under O2, H2 and reactive gas mixtures.

Interfacial Assembly of Robust TiO2 Nanosheets Onto Silica-Modified Reduced Graphene Oxide for Highly Efficient Degradation of Organic Dyes

Interfacial Assembly of Robust TiO2 Nanosheets Onto Silica‐Modified Reduced Graphene Oxide for Highly Efficient Degradation of Organic Dyes

Robust TiO2 nanosheets: Ultrathin TiO2 nanosheets of about 4 nm are uniformly decorated onto the surface of silica-modified reduced graphene oxide (RGO). These robust TiO2 nanosheets interconnect each other and form a unique net-like architecture. Significantly, the TiO2@RGO products show superior structural stability and excellent photocatalytic activity for degradation of organic dyes.

Controlled Attachment of Pseudomonas aeruginosa with Binary Colloidal Crystal‐Based Topographies

Binary colloidal crystal (BCC) surfaces with variable topographies are fabricated via an evaporation-induced method. A thin coating with identical chemistry is deposited on top of the different BCC topographies using an allylamine plasma polymer (AAMpp). The BCC surfaces with micrometer-sized topography can easily trap bacteria and delay biofilm formation despite the presence of the highly adhesive AAMpp.

Easily fabricated photomobile liquid-crystalline polymer films are developed using N-benzylideneaniline as a photoresponsive mesogenic crosslinker. Upon exposure to UV light, the film exhibits macroscopic bending and then spontaneously reverts to the initial shape when the light is turned off. The bending behavior is affected by the surface composition of the film determined by the preparation process.

A method for making high surface area hybrid materials (up to 130 m2 g−1) consisting of grafted Ti sites on chitosan is described. Control over Ti grafting conditions is shown to induce the self-organization into a unique spatial pattern. This pattern is correlated to cooperative interactions between Ti and the primary amines during catalytic testing.

Diazonium Grafting Control through a Redox Cross‐Reaction: Elucidation of the Mechanism Involved when using 2,2‐Diphenylpicrylhydrazyl as an Inhibitor

Hard graft: Carbon functionalization is investigated by using diazonium chemistry in the presence of 2,2-diphenylpicrylhydrazyl (DPPH). Previously assumed to be caused by radical capture, the control mechanism is in fact based on a redox reaction involving the reduced form of DPPH. The approach is extended to the use of substituted benzoquinones as grafting inhibitors and can produce modulated surface coverages.

The spontaneous emission lifetime of organic chromophores located near hyperbolic metamaterial (HMM) multilayer nanostructures is independent of the number of pairs in the surface plasmon polaritons, and emission interference dominant regimes, while it decreases in the hyperbolic dispersion dominant regime. The spontaneous emission lifetime is similarly affected by transverse positive and transverse negative HMMs.

A random copolymer of polyhedral oligomeric silsesquioxane (POSS) methacrylate and 2-(methacryloyloxy)ethyl phosphorylcholine (MPC) improves both surface and bulk properties. It is found that only the POSS bearing ethyl group induces the increased mechanical strength, low surface wettability, and cellular attachment. The finding is anticipated to be tuned for both surface and bulk functions of poly-MPC for biomedical applications.
