Evidence that aciniform silk and minor ampullate silk are major constituents of wrapping silk from the black widow
<p>Spider silk is one of the most remarkable materials produced in the natural world and its strength and extensibility are legendary. To date, the majority of studies have been performed on the following silks: dragline, capture spiral, and eggcase silk. The primary goal of this study was to …

Spinning of synthetic spider silk-like fibers and ex vivo rheology of spider silk
Spider silk has been hailed as nature's super-fiber based on its mechanical properties. A synthetic analog would have numerous applications, from the textile industry to suspension cables for bridges. This thesis discusses attempts to spin a synthetic spider silk-like material (a concentrated …

Conceptualizing Silk Road as countercultural rebellion
Silk Road (SR) is an anonymous online illicit marketplace (OIM) that is often cited as an example of criminal innovation. I add that SR is more than just a marketplace and should be considered as a demonstration of rebellion. The aim of this research is to critically co-construct a definition of SR …

Fog Harvesting: Inspired by Spider Silk
… This thesis topic is inspired by spider silk's ability to direct water droplets to certain locations to further enhance water collecting rate. This directional droplet movement is caused by spindle-knot and joint structure on the biomimetic silk. The spindle-knot is randomly porous, and …

TISSUE ENGINEERING CELLULARIZED SILK-BASED LIGAMENT ANALOGUES
The resurgence, and eventual rise to prominence in the field of tissue engineering, that electrospinning has experienced over the last decade speaks to the simplicity and adaptability of the process. Electrospinning has been used for the fabrication of tissue engineering scaffolds intended for use …

Biomimicry of the spider silk spinning apparatus
<p>Spider silk is known for its extraordinary material properties, being both very strong and extensible. Even though the fibers outperform many synthetic and natural materials, it is impractical to collect industrial amounts of silk from spiders due to their cannibalistic and venomous nature; they …

For Better Silk : Sericulture Reform in Sichuan, 1901-1945
… These pluralistic pursuits for better silk eventually converged into a single trajectory - the modernization of sericulture controlled and managed by the Chinese government and their professional sericulturists. In examining the technological development of sericulture in modern …

Synthesis and characterization of silk-inspired thermoplastic polyurethane elastomers
… and superior properties observed in spider silk fibers. The silk's toughness is related to a fiber morphology that includes P-pleated crystalline sheets within an amorphous matrix, as well as an additional interphase with an orientation and mobility between that of the two microphases. In …

Molecular dynamics analysis of supercontraction in spider dragline silk
Spider dragline silk is a material that has evolved over millions of years to develop finely tuned mechanical properties. It is a protein-based fiber, used as the main structural component in spider webs and as a lifeline for the spider, and it combines strength and extensibility to give it …

Beyond Silk: A Re-Evaluation Of Jin Painting (1115 - 1234)
… a systematic analysis of painted works on silk, paper, and temple and tomb walls. Although the Jin dynasty lasted for 119 years, Jin painting is treated often as a footnote to the more highly revered painting of the Northern and Southern Song dynasties (960 – 1279). This marginalization is …

Understand The Structure-Water-Responsive Relationship by Engineering Silk Materials
… by engineering <em>Bombyx (B.) mori</em> silkworm silk protein. First, by increasing the silk’s mechanical stiffness as a result of increased silk II structures (β-sheet rich domains) or adding stiff silica nanoparticles, <em>B. mori</em> silk’s WR actuation energy density was dramatically …

Shape analysis for digital representation of East Asian silk patterns
This thesis examines the East Asian geometric silk pattern. Despite its long history of use in traditional architecture as an ornamental element in Korea and China, a little attempt was made to understand its geometric construction. Also, the connection between the silk patterns in two countries …

Scroop, luster, and hand : the science and sensuality of silk
For five thousand years, silk threads have woven through the fabric of human history. Since its accidental discovery in China all that time ago, silk has played roles, major or minor, in many cultures. In both the East and the West, it has cropped up in some rather unexpected places. Silk's …
