Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Reflected Waves in an Inhomogeneous Excitable Medium [PDF]
SIAM Journal on Applied Mathematics, 1996 Summary: Propagation can be encumbered in an excitable cable in which intrinsic properties change abruptly. A sudden increase in diameter or a decrease in conductivity or excitability can lead to propagation block or delay in propagation with or without reflection. We study such transient phenomena from a geometric point of view.

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.

Reflection of a Wave by a Cylindrical Mirror [PDF]
Proceedings of the Edinburgh Mathematical Society, 1956 The question of the reflection of a wave by a cylindrical mirror is of interest in a number of fields. It is a problem in which it is difficult to obtain an expression for the reflected or scattered field without recourse to physical assumptions which are sometimes somewhat dubious. An attempt was made by Sommerfeld to solve the problem of a plane wave

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView.Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Reflections on wave reflections in chronic thromboembolic pulmonary hypertension [PDF]
European Heart Journal, 2007 Chronic thromboembolic pulmonary hypertension (CTEPH) is a surgically curable form of severe pulmonary hypertension.1 However, in ∼10% of the patients, the procedure may not be successful, because of persistent pulmonary hypertension after removal of proximally located thromboembolic material. This complication is of particularly poor prognosis. In the
