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

open access: yesAdvanced 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.

Calculating dispersion relations for waveguide immersed in perfect fluid

open access: yesMathematical Modelling and Analysis, 2018
Conventional finite element method (FEM) is capable of obtaining wave solutions, but large discretized structures at high frequency require high computational resources, the computational domain can be reduced by combining FEM with analytical assumption ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced 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.

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

open access: yesAdvanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Symbolic-numeric research of leaky modes in planar dielectric electromagnetic waveguide as inhomogeneous waves

open access: yes
In the case of guided and radiation modes of open waveguides, the Sturm-Liouville problem is formulated for self-adjoint second-order operators on the axis and the corresponding eigenvalues are real quantities for dielectric media.

Length-dependent effects due to leaky modes on multimode graded-index optical fibres

open access: yes, 1976
The radiation losses of tunnelling leaky modes in graded-index optical fibres are calculated theoretically, and it is shown that the near-field intensity profile has a length dependence.

On the excitation of trapped and leaky modes in coronal slabs

open access: yes, 2005
We study the excitation of fast waves in solar coronal loops modeled as smoothed, dense plasma slabs in a uniform magnetic field. We analyse the features of the trapped and leaky modes which result from an initial disturbance generated in the loop.

Leaky-modes excitation in thermally poled nanocomposite glass and their exploitation for saturable absorption [PDF]

open access: yes, 2010
Thermal poling is used to create a reduced index layer in a soda-lime/nanocomposite film. Leaky-modes have been exploited to enhance interaction of light with Au-nanoparticles and demonstrate saturable absorption characteristics in line with state-of-the-
