Multi-stage keyhole evolution in fiber laser welding: An experimental study and theoretical analysis
Results in Physics, 2021 Laser welding with high beam intensity generates a metal vapor, which partially displaces the metal melt, forming a narrow keyhole-shaped fusion zone. This study conducted theoretical analysis of the keyhole formation processes within fiber laser welding,

Advanced Engineering Materials, EarlyView.Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

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.

Advanced Healthcare Materials, EarlyView.Platelet quality deteriorates during storage due to protein and platelet adhesion to current bag materials. Here, polymer coatings are identified that reduce adhesion and translated them to mini‐storage bags. Platelet quality are not impacted, despite significantly reducing adhesion.
