Publication number: 20250082828Abstract: Described herein are medical devices and medical implements with high lubricity to flesh (or biological fluid) and/or inhibited nucleation on its surface. The device has a surface comprising an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between said solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface.Type: ApplicationFiled: April 17, 2024Publication date: March 13, 2025Applicant: Massachusetts Institute of TechnologyInventors: J. David Smith, Rajeev Dhiman, Adam T. Paxson, Christopher J. Love, Brian R. Solomon, Kripa K. Varanasi

Publication number: 20240125028Abstract: Indigo-dyed garments are treated with an anti-ozone agent to prevent ozone-related degradation of the garments before laser finishing. Without treatment, the garments can exhibit color loss (e.g., color change or fading) from exposure to ozone in the atmosphere. The indigo-dyed garments with anti-ozone treatment can serve as base templates in a laser finishing process flow. The anti-ozone treatment of the base templates can include a rinse including an ascorbic acid or vitamin C constituent during a base preparation process. Then quantities of these base templates can manufactured and stored for periods of time without exhibiting ozone-related degradation effects.Type: ApplicationFiled: July 18, 2023Publication date: April 18, 2024Inventors: James Barton Sights, David Love, Elizabeth O'Neill, Benjamin Bell, Jennifer Schultz, Christopher Schultz, Debdulal Mahanty, Sachith Devendra Samarasinghe, Chatura Atukorala, Jeff Zens

Publication number: 20240099408Abstract: Delayed finishing of apparel products, such as by way of laser finishing, allows an operating model that reduces finishing cost, lowers carrying costs, increases productivity, shortens time to market, be more reactive to trends, reduce product constraints, reduces lost sales and dilution, and more. Improved aspects include design, development, planning, merchandising, selling, making, and delivering. The model uses fabric templates, each of which can be used to produce a multitude of finishes. Operational efficiency is improved.Type: ApplicationFiled: December 5, 2023Publication date: March 28, 2024Inventors: James Barton James, David Love, Elizabeth O'Neill, Jeff Zens
