Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

The assessment of track deflection and rail joint performance [PDF]
, 2018 Track stiffness is the one of the most critical parameters of the track structure. Its evaluation is important to assess track quality, component performance, localised faults and optimise maintenance periods and activities.

Deflection-based load transfer efficiency of Floating Slab Track
KSCE Journal of Civil Engineering, 2014 Recently many railway stations have been built under the railway line in urban areas. The passage of railway vehicles generates mechanical vibrations in a wide frequency range. A structural vibration isolation system has been proposed to reduce vibration and noise originating from surrounding environments. The slab track system on elastometric bearings

Investigating the Behavior of Railway Sleeper for Different Cases and Track Conditions by Using Analytical and Numerical Methods [PDF]
International Journal of Railway Research, 2021 Railway Sleepers are one of the most important elements in the track superstructure. Their tasks are keeping the track geometry, resisting against vertical and lateral train loads and transferring the train loads to the ballast layers.

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

The Influence of Seasonal Effects on Railway Vertical Track Modulus
InfrastructuresAdequate vertical track support is essential for safe and efficient railway operations. Insufficient support leads to distorted track geometry, increased dynamic loads, component stress, poor ride quality, rolling stock damage, and derailment risks ...

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
