Repair of honeycomb panels with welded breakaway studs [PDF]
, 1969 Damaged metallic honeycomb panels can be repaired by drilling holes and welding breakaway studs to both facing sheets. Minimal heat required for welding reduces distortion of highly stressed panels.

Gradients of Aliveness and Engineering: A Taxonomy of Fungal Engineered Living Materials
Advanced Materials, EarlyView.This paper explores the potential of fungal engineered living materials (ELMs), examining fungal biology and growth mechanisms, which underpin their development. It presents a classification framework based on aliveness, scaffold composition, and engineering degree. Unique properties such as self‐healing, biosensing, and bioremediation are highlighted,

Advanced Materials, EarlyView.Reversible adhesion via host–guest complex formation at the polymer interface is achieved by externally controlling the complexation through applied stimuli. Neutron reflectometry analysis of the adhesion interface revealed that the presence of host–guest complexes hinders the polymer interdiffusion by despite promoting adhesion strength.

Welding blades to rotors [PDF]
, 1973 A process is described to form T-joints between dissimilar thickness parts by magnetic force upset welding. This type of resistance welding is used to join compressor and turbine parts which thereby reduces the weight and cost of jet ...

Advanced Materials, EarlyView.Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,
