H2O2 generation at carbon paste electrode with decamethylferrocene solution in 2-nitrophenyloctyl ether as a binder. The catalytic effect of MoS2 particles

Here, we report hydrogen peroxide generation at 2-nitrophenyloctyl ether (NPOE)-water interface with decamethylferrocene as an electron donor. The progress of this reaction was detected by the observation of color change of the organic and aqueous phases in series of shake-flask experiments. The shape change of cyclic voltammograms recorded at carbon paste electrode with decamethylferrocene solution in NPOE also indicates (electro)catalytic reaction. Hydrogen peroxide was electrochemically detected at Pt microelectrode tip positioned in front of carbon paste electrode. For this purpose, scanning electrochemical microscopy (SECM) approach curves were recorded. Analogous experiments demonstrated the possibility of electrochemical regeneration of the electron donor. The (electro)catalytic effect of MoS2 on hydrogen peroxide generation was found by both shake-flask and SECM experiments.

Ag fractals formed on top of a porous TiO2 thin film

Ag:TiO2 nanocomposite thin films were prepared by magnetron sputtering and the mechanism associated to the formation of dendrite-type fractals was found to be controlled by diffusion-limited-aggregation of Ag atoms, promoted by a thermal annealing. The fractal structures that were formed became surrounded by a porous TiO2 matrix, and are expected to find important applications in surface enhanced spectroscopies and plasmonic sensing.

Freestanding Ultrathin Nanoparticle Membranes Assembled at Transient Liquid–Liquid Interfaces

Freestanding Ultrathin Nanoparticle Membranes Assembled at Transient Liquid–Liquid Interfaces

Membranes of cross-linked Au Nanoparticles (NPs) are assembled at an oil–water interface during the coalescence phase. Owing to the decreasing surface available, Au NPs are driven to pack and form a membrane, constituted of one or a few monolayers, which spans over square centimeters. The process is compatible with the coassembly of other nano­sized objects, as demonstrated with carbon nanotubes.

On the Generation of Polyether-Based Coatings through Photoinduced C,H Insertion Crosslinking

On the Generation of Polyether‐Based Coatings through Photoinduced C,H Insertion Crosslinking

Photoreactive polymer systems are synthesized from a commercially available polyether via polymer analogous introduction of benzophenone moieties. The obtained polymers are able to create surface-attached polymer networks upon brief UV irradiation via C,H insertion crosslinking. The BP-modified polymers can serve as negative photo-resists which allow in a very simple manner the generation of relief structures on various substrates, even on chemically rather inert polymer substrates such as polyolefins.

Nanoscale Control Over Interfacial Properties in Mixed Reverse Micelles Formulated by Using Sodium 1,4-bis-2-ethylhexylsulfosuccinate and Tri-n-octyl Phosphine Oxide Surfactants

Nanoscale Control Over Interfacial Properties in Mixed Reverse Micelles Formulated by Using Sodium 1,4‐bis‐2‐ethylhexylsulfosuccinate and Tri‐n‐octyl Phosphine Oxide Surfactants

Reverse micelles: At low water content, incorporation of tri-n-octyl phosphine oxide (TOPO) in sodium 1,4-bis-2-ethylhexylsulfosuccinate (AOT) reverse micelles causes a progressive decrease in the mixed interfacial micropolarity, the hydrogen-bond donor capability of water, and the “bulk-like” water formation (see figure; QB=1-methyl-8-oxyquinolinium betaine).

Surface and Interface Modified Thermal, Structural and Charge Transport Properties in Conjugated Polymer Thin Films

Surface and Interface Modified Thermal, Structural and Charge Transport Properties in Conjugated Polymer Thin Films

Surface and interface effects can virtually split a conjugated polymer thin film into vertically heterogeneous layers, each having different thermal and structural properties, leading to the deviations of these properties near surface and interface regions compared to those in the bulk of the film, and consequently affecting electronic properties of the thin film.

Manganite/Cuprate Superlattice as Artificial Reentrant Spin Glass

Manganite/Cuprate Superlattice as Artificial Reentrant Spin Glass

Reentrant spin glass state with enhanced ferromagnetism is observed in ultrathin manganite/cuprate superlattices made of ferromagnetic La0.7Sr0.3MnO3 and antiferromagnetic La2CuO4. The evolution of the rich magnetic properties is attributed to the competition between multiple energetic ground states at the interfaces, which is confirmed by first-principles calculations.

Thumbnail image of graphical abstract

The evolution of the solid electrolyte interface (SEI) in carbon-coated ZnFe2O4 (ZFO-C) anodes is studied by soft X-ray absorption spectroscopy (XAS). Experiments probe locally the SEI growth in the 2–100 nm range, using both total electron (TEY) and total fluorescence (TFY) yield techniques. XAS analysis shows that the SEI grows preferentially around the ZFO-C nanoparticles.
