Fatigue Behavior of Welded Connections Enhanced with UIT and Bolting [PDF]
, 2008 A common problem in bridges employing welded steel girders is development of fatigue cracks at the ends of girder coverplates. Fatigue cracks tend to form at the toes of the transverse welds connecting a coverplate to a girder flange since this detail ...

Platform Thinking as a Catalyst for Circular Innovation in Low‐ and Medium‐Tech Industries
Business Strategy and the Environment, EarlyView.ABSTRACT Growing pressures to replace linear with circular models challenge organisations to innovate continuously and to absorb new knowledge. While platform thinking has been examined as an enabler of innovation in high‐tech industries, its relevance in low‐ and medium‐tech industries, like construction, remains underexplored.

Business Strategy and the Environment, EarlyView.ABSTRACT Circular innovation (CI) research has identified a wide range of circular strategies and design approaches, yet offers limited insight into how CI evolves as a learning process within firms and which governance mechanisms guide this progression. Drawing on organizational learning (OL), this study examines how exploration and exploitation shape

Carbon Energy, EarlyView.An ionomer‐free anode catalyst layer is fabricated via rapid Joule heating, partially embedding IrO2 nanoparticles into the membrane to form a robust, anchored interface. This architecture eliminates ionomer‐induced poisoning and mass‐transport barriers, enabling efficient water‐mediated proton transport and electronic connectivity.

Deep Underground Science and Engineering, EarlyView.A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such
