Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis
Advanced Functional Materials, EarlyView.The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Influence of Hysteresis on Magnetocaloric Performance at Cryogenic Temperatures: A Tb3Ni Case Study
Advanced Functional Materials, EarlyView.The existence of an inverse magnetocaloric effect in metamagnetic materials at cryogenic temperatures is investigated using multiple methods. Contrary to predictions from magnetization data, neither specific heat nor pulsed‐field measurements show such a cooling effect, instead indicating irreversible heating.

Understanding Pore Formation in Laser Beam Welding
Physics Procedia, 2011 AbstractThe mechanisms leading to process pores in deep penetration laser beam welding are discussed in this paper. Process pores were observed since the beginning of laser welding. Although there are differences in the number, size and location of the pores depending on the used laser type and beam parameters, process pores are a common problem for ...

Investigation of metal flow in bridge die extrusion of Alloy 6063 and subsequent effect on surface quality and weld seam integrity [PDF]
, 2013 This paper describes a detailed study of tube extrusion by simulation using finite element method (FEM). The finite element model used one-sixth of symmetry. The extrusion load, emperature evolution and metal flow were predicted.

Advanced Functional Materials, EarlyView.Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.

Mechanism of Porosity Formation in Laser Welding.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995 This paper described a model of the porosity formation mechanism and its experimental verification in laser welding. Porosities formed in the molten zone were classified into microporosity and macroporosity according to the porosity size. Moreover, the characteristics of porosities formed in laser welding of the thermal-conductive mode and keyhole mode
