Coupling synthetic biology and programmable materials to construct complex tissue ecosystems Catherine S. Millar-Haskell, Allyson M. Dang, Jason P. Gleghorne
The investigation of biological systems with programmable features stems from the need to systematize the iteration of de novo synthetic biology methods or investigation of new phenomena in an accelerated fashion. However, it is important to relate this to the statistical analysis of population within cultured organisms to provide for tight correlation of experimentation and phenomenological interpretation. This review gives an important overview of this emerging field. https://doi.org/10.1557/mrc.2019.69
On the thermal processing and mechanical properties of 3D-printed polyether ether ketone (PEEK) Russell Wang, Kang-Jie Cheng, Rigoberto C. Advincula, Qiyi Chen
There is a lot of interest in high-performance polymers (HPP) including polyether ether ketone (PEEK) for 3D printing because of properties that can rival metals. In addition, there is interest in using these materials for biomaterials and bio-implant application. This work focuses on highlighting the importance of achieving balance with the crystalline and amorphous domains formed during the layer deposition for optimization of thermomechanical properties. https://doi.org/10.1557/mrc.2019.86
Artificial neural network correction for densityfunctional tight-binding molecular dynamics simulations Junmian Zhu, Van Quan Vuong, Bobby Sumpter, Stephan Irle
This work highlights the use of machine learning and artificial neural networks (NN) to optimize properties of molecular systems involving non-covalent interaction forces. The comparison with typical density functional theory (DFT) methods vs. the application NN in a DFTBNN approach results in faster optimization methods. Eventually, this approach can be used for more complex molecular and even macromolecular systems. https://doi.org/10.1557/mrc.2019.80
Synthesis and characterization of ionene-polyamide materials as candidates for new gas separation membranes Jason E. Bara, Kathryn E. O’Harra, Marlow M. Durbin, Grayson P. Dennis, Enrique M. Jackson, Brian Thomas, Jamiu A. Odutola
Bara and co-authors describe the fabrication of several thermoplastic materials to be used for gas separation membranes. Molecular weights helped identify the likely limiting step in the polymerization. The characterization of thermal properties allowed for subsequent melt processing. One ionene behaves elastomerically, suggesting particularly attractive performance for a separation membrane. https://doi.org/10.1557/adv.2018.376
