Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Downregulation of NAC transcription factors modifies cell wall composition and increases strawberry fruit firmness [PDF]

, 2019
The strawberry is a soft fruit with a very short post-harvest shelf life. The changes in texture during fruit ripening are mainly due to the dissolution of the middle lamellae, reducing cell-to-cell adhesion, and the weakening of parenchymal cell walls ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

Advanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Activation of the ChvG–ChvI pathway promotes survival during cell wall stress in Agrobacterium tumefaciens [PDF]

Agrobacterium tumefaciens shifts from a free-living soil bacterium to a plantinvading state upon encountering the plant root microenvironment. The acid-induced twocomponent sensor system ChvG–ChvI drives this shift and triggers a complex transcriptional ...
