Prediction of withdrawal stiffness of self-tapping screws

, 2023
: Self-tapping screw is a new generation of fasteners which is often inserted into the face of timber membersat an angle to develop stiff and strong connections. The withdrawal stiffness of self-tapping screws is an important property that influences the

Axial Performance of Self-tapping Screws in Mass Timber Products Under Moisture Content Variation [PDF]

, 2022
Self-tapping screws (STS) are widely used in wood-to-wood and wood-to-steel connections in timber structures. The premature failure of STS during the construction phase has been recently reported by structural engineers and contractors of several mass ...

Rotational Stiffness of Timber-to-Timber Connections with Self-Tapping axially loaded Screws [PDF]

, 2023
Self-tapping axially loaded screws provide high load-carrying capacity and great stiffness. Due to these advantages, they were preferably applied to realise connections for tension members.

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

Advanced Functional Materials, EarlyView.
Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes

Advanced Optical Materials, EarlyView.
We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...
