Silk lamellae thickness decreased with decreasing silk concentration, but high molecular weight silk formed intact lamellae at 0.5% wt/v.
To address the limitations of these singular component scaffolds, HA was covalently crosslinked with silk, forming a composite hydrogel that exhibited both mechanical integrity and hydrophilicity.
Although silk forms only fibers in nature, synthetic techniques can be used to control the processing of silk into different morphologies, such as scaffolds, films, hydrogels, microcapsules, and micro- and nanospheres.
Crystalline beta-sheet formation in silk forms physical crosslinks which reinforces the structure of silk imparting enhanced mechanical strength and degradation properties [ 133, 134].
So there they are, stooping and stretching, with the jockeys' silks forming and re-forming magical patches of color.
Confirming earlier experimental and computational work, a structural analysis reveals that poly-alanine regions in silk predominantly form distinct and orderly β-sheet crystal domains while disorderly regions are formed by glycine-rich repeats that consist of 310-helix type structures and β-turns.
Slashed leather and silk, bandaged forms, and satin rosettes jutting in and out of the body formed an impassioned cry for us to feel something – anything.
The French entomologist Jean-Henri Fabre once tricked a line of caterpillars — who dutifully follow the pheromones in one another's silk — into forming a circular trail atop a ceramic palm vase.
The introduction of Arachne (Natalie Mendoza) features some of the first breathtaking images, as a giant loom of interwoven silks takes form on the stage, and Arachne descends over the audience on a platform.
This article focuses on silk fibers formed in caddisflies cocoons of Hydropsyche angustipennis (Insecta, Trichoptera) larvae.
