Chemically Reactive Thin Films: Dynamics and Stability

Advanced Materials Interfaces, EarlyView.
What happens to a thin liquid film when chemical reactions occur inside it? By means of theoretical analysis, it is showed that such systems (which are very common in heterogeneous catalysis) become very dynamic and not only their wetting properties are strongly affected by the chemical activity, moreover their interface can undergo traveling and ...

The Role of Post‐Sintering Heat Treatment on the Phase and Microstructural Development of Nano Cu‐Zno Modified Ceramic Surfaces

Advanced Materials Interfaces, EarlyView.
Nano Cu‐ZnO glazes formed multilayered microstructures. Cu doping and concentrations affect phase evolution and microstructure. Post‐sintering heat treatment and its duration are crucial for creating textured microstructures. Abstract The study examines the effect of heat treatment duration on microstructure and phase evolution concerning Cu content in

Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

Advanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

Advanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.

Assessing the Safety Margin for Micromotion‐Induced Strain at Electrode–Tissue Interface: A Finite Element Analysis via COMSOL

Advanced Materials Interfaces, EarlyView.
Brain movement significantly impacts the biocompatibility of neural probes due to continuous strain on neural tissue. This study examines strain profiles across various brain models and movement types, challenging the 5% damage threshold at the electrode–tissue interface.

Crystallographic Insights into the Structural Heterogeneities of 2D Ruddlesden‐Popper Perovskite Films

Advanced Materials Interfaces, EarlyView.
2D Ruddlesden‐Popper phase perovskite (RPP) films for applications in photovoltaics are shown to exhibit structural heterogeneities at both microscopic and mesoscopic scales that can affect cross‐film charge carrier transport. The mechanisms of RPP film formation and the possible means to control film structure to optimize 2D perovskite solar cell ...

High‐Performance 3D Printed Mechanically Interlocked Soft–Hard Interfaces of Hydrogels and Polylactide

Advanced Materials Technologies, EarlyView.
In this work, a methodology is presented for the design, fabrication and characterization of soft–hard interfaces consisting of extremely soft hydrogel biomaterials, and much harder rigid polymeric biomaterials. This approach enables the production of interfaces with performances close to predicted values, with applications in biomaterial fabrication ...

Finding Edge-Disjoint Paths in Partial k -Trees

Algorithmica, 2000
For a given graph G and p pairs (s i ,t i ) , $1\leq i\leq p$ , of vertices in G , the edge-disjoint paths problem is to find p pairwise edge-disjoint paths P i , $1\leq i\leq p$

Vertex partitioning problems on partial k-trees

, 1996
We describe a general approach to obtain polynomial-time algorithms over partial k-trees for graph problems in which the vertex set is to be partitioned in some way. We encode these problems with formulae of the Extended Monadic Second-order (or EMS) logic. Such a formula can be translated into a polynomial-time algorithm automatically. We focus on the
