The dress, Celestial Indigo, was the result of a collaborative effort between a book author, designer, stitcher, and natural dyers. Tracey Martin (2017), author of Sustainable in Stilettos, is passionate about a book cover’s intrinsic messages. Celestial Indigo, created for Martin’s book cover, holds messages of refashioning, versatility, natural color, and collaboration. A halter dress was refashioned by designing a skirt overlay from silk chiffon torn into strips and through coloration with indigo. The indigo vat was a fermentation vat with fructose as the reducing agent and calcium hydroxide for alkalinity. Sustainable advantages of the fructose fermentation vat compared to a chemical vat are no harsh chemicals (i.e., thiourea dioxide and lye) and elimination of heat beyond initial reduction. To protect undyed and dyed areas, as well as manage the gown bulk, fabric sections were capped with plastic and secured with rubber bands and string

Z-Pinch Generated X-Rays in Static-Wall Hohlraum Geometry Demonstrate Potential for Indirect-Drive ICF Studies
Hohlraums of full ignition scale (6-mm diameter by 7-mm length) have been heated by x-rays from a z-pinch target on Z to a variety of temperatures and pulse shapes which can be used to simulate the early phases of the National Ignition Facility (NIF) temperature drive. The pulse shape is varied by changing the on-axis target of the z pinch in a static-wall-hohlraum geometry. A 2-{micro}m-thick walled Cu cylindrical target of 8-mm diameter filled with 10 mg/cm{sup 3} CH, for example, produces foot-pulse conditions of {minus}85 eV for a duration of {approximately} 10 ns, while a solid cylindrical target of 5-mm diameter and 14-mg/cm{sup 3} CH generates first-step-pulse conditions of {approximately} 122 eV for a duration of a few ns. Alternatively, reducing the hohlraum size (to 4-mm diameter by 4-mm length) with the latter target has increased the peak temperature to {approximately} 150 eV, which is characteristic of a second-step-pulse temperature. In general, the temperature T of these x-ray driven hohlraums is in agreement with the Planckian relation (T-(P/A){sup 1/4}). P is the measured x-ray input power and A is the surface area of the hohlraum. Fully-integrated 2-D radiation-hydrodynamic simulations of the z pinch and subsequent hohlraum heating show plasma densities within the useful volume of the hohlraums to be on the order of air or less
