Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

Advanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Detectability of Varied Hybridization Scenarios Using Genome-Scale Hybrid Detection Methods

Bulletin of the Society of Systematic Biologists
  Hybridization events complicate the accurate reconstruction of phylogenies, as they lead to patterns of genetic heritability that are unexpected under traditional, bifurcating models of species trees. This phenomenon has led to the development of methods to infer these varied hybridization events, both methods that reconstruct networks directly, as ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

Advanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Supersymmetric hybrid inflation in the braneworld scenario

Physics Letters B, 2003
في هذه الرسالة، نعيد النظر في التضخم الهجين الفائق التناظر في سياق سيناريو عالم الدماغ. يتم استيفاء حدود المراقبة بمقياس طاقة تضخمي μ × 4×10− 4 ميجابكسل، دون أي ضبط دقيق لمعلمة الاقتران، بشرط أن يكون مقياس بلانك خماسي الأبعاد هو M5 × 2×10− 3ميجابكسل. لقد حصلنا أيضًا على حد أعلى لشد الغشاء.
