Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

Compositional Gradient–Engineered Ti–WO3 Films for Simultaneous Enhancement of Coloration Efficiency and Mechanical Robustness

open access: yesSmall, EarlyView.
A gradient Ti‐doped WO3 electrochromic film is developed via dynamic co‐sputtering, enabling depth‐dependent band engineering and strain regulation. The gradient structure induces a built‐in electric field across the film thickness that enhances coupled ion–electron transport while improving mechanical robustness.
