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

International 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 ...

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

Polymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

Phytochemical‐Based Strategies for Lung Cancer: Clinical Insights Into Pleiotropic Molecular Signaling and Therapeutic Roles

Phytotherapy Research, EarlyView.
Lung cancer (LC) remains the leading cause of global cancer‐related death. Phytochemicals from medicinal plants are increasingly being considered as potential LC treatment agents due to their multi‐targeted action, safety, and accessibility. These have anticancer properties by regulating key molecular signaling pathways.

SensHB.Q: A Cost‐Effective Force‐Sensitive Handlebar to Control Omnidirectional Robots and Wheelchairs

Journal of Field Robotics, EarlyView.
ABSTRACT This paper details the design and development of SensHB.Q, a force‐sensitive handlebar intended for caregivers driving electric‐powered wheelchairs, particularly those with omnidirectional mobility. The same interface can also be used in the future to operate other omnidirectional motorized systems, such as mobile robots, hospital beds, and ...
