Review on Processing Control Strategy for Electrochemical Additive Manufacturing

MetalMat, EarlyView.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

Remote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

Rail inspection of RCF defects

Metalurgija, 2013
Rail defects due to rolling contact fatigue (RCF) threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European railway network demands from every infrastructure manager to have a maintenance plan for the infrastructure subsystem.

Sentipensar [Feel‐Thinking] Cultivates Collective Scientific Sensemaking and Worldbuilding Within and Beyond Ecological Despair

Science Education, EarlyView.
ABSTRACT Educating youth about environmental and climate justice is crucial in realizing a sustainable and flourishing future. Yet this can be challenging given the intense eco‐emotions youth experience and express while learning about these consequential realities and their implications.

A feasibility study on in-service non-destructive inspection of railway rails by an ultrasonic technique based on travelling electromagnetic acoustic transducers

Railway Engineering Science
This study explores the feasibility of electromagnetic acoustic transducers (EMATs) for ultrasonic rail inspection, focusing on bulk wave generation from the rail head and on defect detection at the central part of the rail foot. As a contactless method,

Sustainable Cities Under Pressure: Climate Risk, Oil Price Uncertainty, and Technological Innovation in GCC Countries

Sustainable Development, EarlyView.
ABSTRACT This study examines the dynamic interactions between climate risk, oil price uncertainty (OPU), and technological innovation in shaping Sustainable Development Goals (SDGs) related to Sustainable Cities and Communities (SCC) across Gulf Cooperation Council (GCC) countries from 2005 to 2024. Using a panel Time‐Varying Interactive Fixed Effects (

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, EarlyView.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse. To
