The Role of Graphite-like Carbon Films in Mitigating Fretting Wear of Slewing Bearings
MachinesWe aimed to address the issue of fretting wear on the rollers and raceways of pitch bearings in wind turbines during shutdown and under intermittent high loads. This study focuses on triple-row cylindrical roller bearings.

Dynamic simulation of cylindrical roller bearings
, 2014 In this work, a three-dimensional dynamic simulation model for cylindrical roller bearings is developed based on multi-body-simulation software SIMPACK and programming language FORTRAN. The aim of this work is to build a universal program to calculate the dynamic behavior of cylindrical roller bearings.

Advanced Science, EarlyView.Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.

Basal Plane Graphene Coated Zn Powder for High Performance Aqueous Zn Metal Batteries
Advanced Science, EarlyView.A mechanofusion‐driven dry coating forms a hydrophobic graphene shell on Zn powder, stabilizing the electrode‐electrolyte interface. This basal‐plane‐rich protective layer modifies the Zn2+ solvation environment and promotes preferential growth along the (002) plane, suppressing dendrite and parasitic reactions.
