Determination of the force necessary by experiment to bend schedule 40 pipe [PDF]

Científica
The tube bending process consists of plastically deforming the material by applying bending loads to the element until its yielding is overcome. Mechanical bending tests help determine the properties of a material, properties that are used to design the ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...
