Cellulose and xylan nanofiber mats via electrospinning: Lignin-enhanced properties in wood-inspired biocomposites

Carbohydrate Polymer Technologies and Applications
Nanofiber mats were fabricated by combining cellulose, xylan, and organosolv lignin. The biopolymers, and a small amount (15 wt. %) of polyethylene oxide, were dissolved in a mixture of trifluoroacetic acid and trifluoroacetic anhydride, then blended in ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

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.
