Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,

A Noninvasive Approach to Study Localized Forces in 3D Epithelia
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Mechanisms of failure of jointed rock masses and the behaviour of steep slopes [PDF]
The geomorphological behaviour of steep jointed rock slopes has been studied using distinct element method computer models. In order to model steep slopes effectively, methodologies need to be combined from the studies of environmental modellers ...

Smart‐Release Ion‐Exchanged Ca‐Montmorillonite for Corrosion Protection of AA2024 Aluminium Alloy
Smart‐release anticorrosion pigments based on Zn‐ and Mn‐modified montmorillonite were developed by ion exchange of Ca‐montmorillonite and evaluated for the protection of AA2024 aluminium alloy in artificial acid rain. Both modified pigments provided effective corrosion inhibition, with Zn‐modified montmorillonite (Zn‐MMT) achieving an inhibition ...

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

STRESSES AROUND A TUNNEL PASSING THROUGH A LAYERED ROCK MASS
ABSTRACT: The article addresses the issue of determining the stresses around a tunnel with a circular cross-section. It passes through several rock layers. The boundary planes between the layers are arbitrarily inclined relative to the tunnel axis. Furthermore, the planes are parallel to the horizontal axis of the tunnel crosssection.The specified ...
