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.

Layer‐by‐layer self‐assembly of multifunctional enzymatic UF membranes

Journal of Applied Polymer Science, 2019
ABSTRACTIn order to eliminate membrane fouling and to ensure enzymatic hydrolysis of urea, multifunctional biocatalytic membranes were prepared by using urease (URE) and trypsin (TRY) enzymes on the sulfonated polysulfone (SPSf) ultrafiltration membrane via layer‐by‐layer (LbL) self‐assembly method.

Effects of the nature and charge of the topmost layer in layer by layer self assembled amperometric enzyme electrodes

Physical Chemistry Chemical Physics, 2010
Organized layer-by-layer nanostructured amperometric enzyme electrodes with self-contained redox polyelectrolyte mediators have shown important effects depending on the nature and charge of the adsorbed topmost layer. Adsorption of PVS causes the drop of the catalytic responses to negligible values due to hindrance in electron hopping and enzyme wiring.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
