The reaction between 1,3,5-tris (4-aminophenyl) benzene and 1,3,5-benzenetricarbaldehyde in acetic acid under continuous microfluidic flow conditions leads to the formation of a highly crystalline and porous covalent organic framework (hereafter denoted as MF-COF-1), consisting of fibrillar micro-structures, which have mechanical stability that allows for direct drawing of objects on a surface.

DOI: http://dx.doi.org/10.1016/j.cub.2017.02.060 | Summary Plastics are synthetic polymers derived from fossil oil and largely resistant to biodegradation. Polyethylene (PE) and polypropylene (PP) represent 92% of total plastic production. PE is largely utilized in packaging, representing 40% of total demand for plastic products (www.plasticseurope.org) with over a trillion plastic bags used every year [1]. Plastic production has increased exponentially in the past 50 years (Figure S1A in Supplemental Information, published with this article online). In the 27 EU countries plus Norway and Switzerland up to 38% of plastic is discarded in landfills, with the rest utilized for recycling (26%) and energy recovery (36%) via combustion (www.plasticseurope.org), carrying a heavy environmental impact. Therefore, new solutions for plastic degradation are urgently needed. We report the fast biodegradation of PE by larvae of the wax moth Galleria mellonella, producing ethylene glycol.

Arrudaa,b, c, , , M.D. Thoulessa, d, ,a Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI 48109, USA b Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA c Macromolecular Science & Engineering Program, University of Michigan, Ann Arbor, MI 48109, USA d Department of Materials Science & Engineering, University of Michigan, Ann Arbor, MI 48109, USA https://doi.org/10.1016/j.jmps.2015.09.009 Abstract The features of blast and impact that can damage a delicate target supported by a structure include both the peak pressure and the impulse delivered to the structure. This study examines how layers of elastic and visco-elastic materials may be assembled to mitigate these features. The impedance mismatch between two elastic layers is known to reduce the pressure, but dissipation is required to mitigate the transmitted impulse in light-weight armor. A novel design concept called impact or blast tuning is introduced in which a multi- layered armor is used to tune the stress waves resulting from an impact or blast to specific frequencies that match the damping frequencies of visco-elastic layers. The material and geometrical parameters controlling the viscous dissipation of the energy within the armor are identified for a simplified one-dimensional system, to provide insight into how the optimal design of multi-use armor might be based on this concept.
