Electrochemical Surface Nanostructuring of Ti47Cu38Fe2.5Zr7.5Sn2Si1Ag2 Metallic Glass for Improved Pitting Corrosion Resistance

open access: yesAdvanced Engineering Materials, Volume 26, Issue 11, June 2024.
Pseudo‐dealloying is presented on a bulk glass‐forming Ti47Cu38Fe2.5Zr7.5Sn2Si1Ag2 alloy as a surface treatment to reduce Cu in the near‐surface region while generating nanostructured Ti and Zr oxide layers. These oxide layers are able to suppress chloride‐induced pitting corrosion in a simulated physiological solution.

Simulation on the performance and cooling capacity compensation solution of a loop thermosyphon system under fan failure conditions

open access: yesCase Studies in Thermal Engineering
Fan failure of loop thermosyphon systems (LTS) is a major factor affecting thermal safety of data centers. This paper develops a distributed-parameter model to accurately predict the overall and local heat transfer performance of a loop thermosyphon (the

Uncertainty Management at the Airport Transit View

open access: yesAerospace, 2018
Air traffic networks, where airports are the nodes that interconnect the entire system, have a time-varying and stochastic nature. An incident in the airport environment may easily propagate through the network and generate system-level effects.
