Abstract
Solid polymer electrolytes (SPEs) offer several advantages compared to their liquid counterparts, and much research has focused on developing SPEs with enhanced mechanical properties while maintaining high ionic conductivities. The recently developed polymerization-induced microphase separation (PIMS) technique offers a straightforward pathway to fabricate bicontinuous nanostructured materials in which the mechanical properties and conductivity can be independently tuned. In this work SPEs with tunable mechanical properties and conductivities are prepared via digital light processing 3D printing, exploiting the PIMS process to achieve nanostructured ion-conducting materials for energy storage applications. A rigid crosslinked poly(isobornyl acrylate-stat-trimethylpropane triacrylate) scaffold provided materials with room temperature shear modulus above 400 MPa, while soft poly(oligoethylene glycol methyl ether acrylate) domains containing the ionic liquid 1-butyl-3-methylimidazolium bis-(trifluoromethyl sulfonyl)imide endowed the material with ionic conductivity up to 1.2 mS cm-1 at 30 °C. These features make the 3D-printed SPE very competitive for applications in all solid energy storage devices, including supercapacitors.

Abstract
The development of advanced solid-state energy-storage devices is contingent upon finding new ways to produce and manufacture scalable, high-modulus solid-state electrolytes that can simultaneously provide high ionic conductivity and robust mechanical integrity. In this work, an efficient one-step process to manufacture solid polymer electrolytes composed of nanoscale ion-conducting channels embedded in a rigid crosslinked polymer matrix via Digital Light Processing 3D printing is reported. A visible-light-mediated polymerization-induced microphase-separation approach is utilized, which produces materials with two chemically independent nanoscale domains with highly tunable nanoarchitectures. By producing materials containing a poly(ethylene oxide) domain swelled with an ionic liquid, robust solid polymer electrolytes with outstanding room-temperature (22 °C) shear modulus (G' > 108 Pa) and ionic conductivities up to σ = 3 × 10-4 S cm-1 are achieved. The nanostructured 3D-printed electrolytes are fabricated into a custom geometry and employed in a symmetric carbon supercapacitor, demonstrating the scalability of the fabrication and the functionality of the electrolyte. Critically, these high-performance materials are manufactured on demand using inexpensive and commercially available 3D printers, which allows the facile modular design of solid polymer electrolytes with custom geometries.

Abstract
Laboratory models of the tumor microenvironment require control of mechanical and biochemical properties to ensure accurate mimicry of patient disease. In contrast to pure natural or synthetic materials, hybrid approaches that pair recombinant protein fragments with synthetic scaffolding show many advantages. Here we demonstrate production of a recombinant bacterial collagen-like protein (CLP) for thiol-ene pairing to norbornene functionalized hyaluronic acid (NorHA). The resultant hydrogel material shows an adjustable modulus with evidence for strain-stiffening behavior that resembles natural tumor matrices. Cysteine terminated peptide binding motifs are incorporated to adjust the cell-adhesion points. The modular hybrid gel shows good biocompatibility and was demonstrated to control cell adhesion, proliferation, and the invasive properties of MCF7 and MD-MBA-231 breast adenocarcinoma cells. The ease in which multiple structural and bioactive components can be integrated provides a robust framework to form models of the tumor microenvironment for fundamental studies and drug development.

Abstract
An original wireless stimulator for peripheral nerves based on a metal loop (diameter ≈1 mm) that is powered by a transcranial magnetic stimulator (TMS) and does not require circuitry components is reported. The loop can be integrated in a chitosan scaffold that functions as a graft when applied onto transected nerves (graft-antenna). The graft-antenna is bonded to rat sciatic nerves by a laser without sutures; it does not migrate after implantation and is able to trigger steady compound muscle action potentials for 12 weeks (CMAP ≈1.3 mV). Eight weeks postoperatively, axon regeneration is facilitated in transected nerves that are repaired with the graft-antenna and stimulated by the TMS for 1 h per week. The graft-antenna is an innovative and minimally-invasive device that functions concurrently as a wireless stimulator and adhesive scaffold for nerve repair.

Abstract
Aquaculture has long been seen as a sustainable solution to some of the world's growing food shortages. However, experience over the past 50 years indicates that infectious diseases caused by viruses, bacteria, and eukaryotes limit the productivity of aquaculture. In extreme cases, these types of infectious agents threaten the viability of entire aquaculture industries. This article describes the threats from infectious diseases in aquaculture and then focuses on one example (QX disease in Sydney rock oysters) as a case study. QX appears to be typical of many emerging diseases in aquaculture, particularly because environmental factors seem to play a crucial role in disease outbreaks. Evidence is presented that modulation of a generic subcellular stress response pathway in oysters is responsible for both resistance and susceptibility to infectious microbes. Understanding and being able to manipulate this pathway may be the key to sustainable aquaculture.
