Study of the Effect of Process Parameters and Heat Treatment on the Formation and Evolution of Directed Energy Deposition of IN718‐CuCrZr Interface

open access: yesAdvanced Engineering Materials, EarlyView.
Bimetallic structures of Inconel 718 and CuCrZr are fabricated using the laser powder directed energy deposition method. The study reveals a strong dependence of interface characteristics such as width and interfusion on processing and heat treatment strategies.

Wind turbine noise [PDF]

open access: yesBMJ, 2012
Seems to affect health adversely and an independent review of evidence is needed The evidence for adequate sleep as a prerequisite for human health, particularly child health, is overwhelming. Governments have recently paid much attention to the effects of environmental noise on sleep duration and quality, and to how to reduce such noise.1 However ...

Single‐Crystal Castability of CM186LC Nickel‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
The optimal conditions to obtain single‐crystal (SX) castings of the directional solidification nickel‐based superalloy CM186LC, are investigated. Cylindrical samples are cast via a proprietary SX Bridgman process. The effect of solidification rates (V) ranging from 1 to 10 mm⋅min−1 on the microstructure is explored.

Coupling Interfacial Redox‐Reactions with In Situ Proton Generation for the Photoelectrochemical Separation of Rare‐Earth Elements

open access: yesAdvanced Functional Materials, EarlyView.
To enhance the sustainability of electrochemical separations for resource recovery, a photoelectrochemical ion recovery system is developed that utilizes renewable solar energy. A composite integrating titianium dioxide nanorods and a redox‐copolymer enables spontaneous cation adsorption and light‐activated redox reactions for regeneration, thus ...
