Structural hierarchy through self-assembly

Architected materials with nano and microscale features can have extraordinarily high strength, stiffness, and toughness per weight. Two well-known biological materials with these characteristics are nacre (mother of pearl)¹ and the claw of the mantis shrimp.² These materials are made of up periodic arrangements of hard domains interspersed with soft matter (Fig. 1). Structural hierarchy exists at different length scales, and varies spatially across the material.

Dear Friends,

Please find our paper on Nature Communications about a novel method to bond hydrogel and elastomers. Comparing to existing methods, our method features the applicability to various manufacturing processes, including dip-coating and 3D printing.

Abstract

We are looking for a C++ or CSharp Programmer and a post-doctoral fellow to couple our in-house Isogeometric BEM/FEM and Collocation approach to Rhino3D. Funding is available for 12 months of post-doc as well as programming time for a GUI and interfacing with Rhino3D. Freelance programmers are welcome to apply. Knowledge of elasticity, linear algebra and BEM acceleration are a plus. 

Contact me for more information including your IGA experience, BEM/FEM experience and background in mechanics. 

Best wishes!

Stéphane

MSG is a powerful tool to analyze the global-local field analysis in any type of composites irrespective of the shape of the constituents. You may check the link here under to see what is happening at microscale due to global loading.

See a national broadcast on Politecnico di BARI and the region Puglia, with its successes, including the worldwide success of Diesel common rail technology, the GE centre on Addittive Manufacturing and Cold Spray, and others.

Mechatronics, the world patent on diesel common rail technology, for which Bosch created a factory of 2000 employees (now, after dieselgate, trying to reconfigure this), biomedical, tribology, etc.

https://doi.org/10.1016/j.eml.2018.01.009 Scleroproteins are an important category of proteins within the human body that adopt filamentous, elongated conformations in contrast with typical globular proteins. These include keratin, collagen, and elastin, which often serve a common mechanical function in structural support of cells and tissues. Genetic mutations alter these proteins, disrupting their functions and causing diseases.
