Our recent review paper on how origami and kirigami techniques that could be used to create curved geometries has been just publised online. It is available as an open access article, which is why I am posting it here. We have also included some beautiful photos of our hand-folded origami and kirigami.

Additive manufacturing (AM) has emerged as a powerful technique for manufacturing of various types of biomaterials and implants. Using AM, it is now possible to fabricate biomaterials with arbitrarily complex shapes at different scales. The inventory of biomaterials that can be used in this way continues to increase, extending the possible range of products and applications.

After several years of research in the area of additive manufacturing, biofabrication, and additively manufactured biomaterials and implants, I finally put up the first version of the website of my lab. I will gradually improve the website, but there is already links to all publications coming out of my lab in the general area of AM.

The mechanical behavior of biomedical materials and biological tissues are important for their proper function. This holds true, not only for biomaterials and tissues whose main function is structural such as skeletal tissues and their synthetic substitutes, but also for other tissues and biomaterials. Moreover, there is an intimate relationship between mechanics and biology at different spatial and temporal scales. It is therefore important to study the mechanical behavior of both synthetic and living biomaterials.

The paramount role of mechanics in life has recently been the center of attention of many researchers. This special issue will be focusing on the role of mechanics in the life of cells and tissues and their interactions with biomaterials. Original research and review papers are solicited for review and publication in the journal Mechanical Sciences . Mechanical Sciences is an academic open-access journal sponsored by the Library of Delft University of Technology and The Netherlands Organization for Scientific Research (NWO).

Deadline for submission of abstracts extended to February 29th.

As a part of ECCOMAS 2012 (European Congress on Computational Methods in Applied Sciences and Engineering)

Submit your Abstract (Choose mini-symposium MS114)

A vacant four-years PhD position is available. This PhD project will be done in Erasmus Medical Center (Rotterdam, NL) in collaboration with Delft University of Technology (Delft, NL) and is a part of a larger Dutch project on regenerative medicine and tissue engineering. The aim of the project is to generate cartilage from bone marrow derived stem cells in culture and evaluate them with molecular assays (Rotterdam) and mechanical assays (Delft). The culture protocol can be varied with oxygen level, tonicity, and active molecules.

Call for Abstracts (Deadline extended to February 12, 2011)

 Submit Your Abstract (Choose mini-symposium MS-149)

I have a one-year vacant postdoc position. The work will be mostly related to development of FE models for modeling growth, differentiation, and adaptation of biological tissues. The postdoc needs to know a lot about nonlinear continuum mechanics and advanced material models and should be able to write FE codes and implement advanced material models in commercial FE programs.

Deadline for submission of abstracts extended to January 18th.

Submit your Abstract (Choose mini-symposium MS114)

Modeling the constitutive behavior of biological tissues often involves anisotropy, hyperelasticity, viscoelasticity, and poroelasticity. I am looking for a good monograph/paper/textbook that presents a general constitutive modeling framework where these aspects are presented in an interconnected way. Most references treat these aspects separately, perhaps devoting a chapter to every aspect.

The first issue of the new interdisciplinary Nature journal (Nature Communications) is avilable online. Here is the description of the journal from the website of the journal:

The recent issue of Nature Materials includes a review paper on the deformation and failure of protein materials in physiologically extreme conditions and disease. The paper was interesting, so I am posting the abstract here. For the full-paper visit Nature Materials.
