“…The incorporation of SWCNTs into the gelatin matrix resulted into a stiffer but also into a more brittle gel, as also reported in recent literature: over a threshold concentration, SWCNTs interfere with the polymer matrix network able to absorb the strain energy, reducing toughness, and causing strain hardening.…”

The aim of this study was set-up and test of gelatin and carbon nanotubes scaffolds. Gelatin-based (5%) genipin cross-linked (0.2%) scaffolds embedding single-walled carbon nanotubes (SWCNTs, 0.3, 0.5, 0.7, 0.9, and 1.3% w/w) were prepared and mechanically/electrically characterized. For biological evaluation, H9c2 cell line was cultured for 10 days. Cytotoxicity, cell growth and differentiation, immunohistochemistry, and real-time PCR analysis were performed. Myoblast and cardiac differentiation were obtained by serum reduction to 1% (C ) and stimulation with 50 nM all trans-retinoic acid (C ), respectively. Immunohistochemistry showed elongated myotubes in C while round and multinucleated cells in C with also a significantly increased expression of natriuretic peptides (NP) and ET-1 receptors in parallel with a decreased ET-1. On scaffolds, cell viability was similar for Gel-SWCNT ; NP and ET systems expression decreased in both concentrations with respect to control and CX-43, mainly due to a lacking of complete differentiation in cardiac phenotype during that time. Although further analyses on novel biomaterials are necessary, these results represent a useful starting point to develop new biomaterial-based scaffolds. © 2017 Wiley Periodicals, Inc.

“…When all GFFS were cooled down to 10°C (Fig. 3b), the G' profiles were nearly ten times as much as those of G", showing all systems a behavior between cross-linked gels and physical gels (G' > G"), as found by Yang et al (2015) at 20°C. According to the n value (Table 1), the behavior of 1.1GFFS was closer to that of a cross-linked gel, followed by 0.6GFFS and the control.…”

The double‐crystal ultra‐small‐angle neutron scattering (USANS) diffractometer KOOKABURRA at ANSTO was made available for user experiments in 2014. KOOKABURRA allows the characterization of microstructures covering length scales in the range of 0.1–10 µm. Use of the first‐ and second‐order reflections coming off a doubly curved highly oriented mosaic pyrolytic graphite premonochromator at a fixed Bragg angle, in conjunction with two interchangeable pairs of Si(111) and Si(311) quintuple‐reflection channel‐cut crystals, permits operation of the instrument at two individual wavelengths, 4.74 and 2.37 Å. This unique feature among reactor‐based USANS instruments allows optimal accommodation of a broad range of samples, both weakly and strongly scattering, in one sample setup. The versatility and capabilities of KOOKABURRA have already resulted in a number of research papers, clearly demonstrating that this instrument has a major impact in the field of large‐scale structure determination.

Investigating linear and nonlinear viscoelastic behaviour and microstructures of gelatin-multiwalled carbon nanotube composites

Abstract: The linear and nonlinear rheology of physically-crosslinked-gelatin gel-multiwalled carbon nanotube (MWNT), chemically-crosslinked-gelatin gel-MWNT, and chemically–physically-crosslinked-gelatin gel-MWNT composites, are investigated.
