Laser‐Based Solidification of Cermets/Cemented Carbides: Processing‐Microstructure‐Property Relationships

Advanced Materials Technologies, EarlyView.
Recent research on laser‐processed cermets and cemented carbides highlights significant advancements, yet a notable paucity of studies and persistent challenges remain. Efforts are increasingly focused on developing low‐cost, environmentally friendly cermets as alternatives to conventional materials.

Co‐simulations of induction machines coupled with a radial ball bearing for mechanical defects analysis

IET Electric Power Applications
In this paper, two co‐simulations are introduced to study the behaviour of a 2‐D finite‐element model and a magnetic equivalent model of an induction machine, both coupled with a mechanical radial ball bearing model.

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

Advanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.
