Systems and methods for incontinence control
A system for managing female incontinence includes a body of biocompatible material configured to fit between the labia minora and the vestibule floor, the body having a surface configured to occlude the urethral meatus, an adhesive carried on at least a first portion of the surface and configured to provide a sealing engagement between the body and the urethral meatus, and a substance carried by at least one of the body and the adhesive and configured for controlling the odor of the general vaginal-urethral area of a female.

ABSORBENT ARTICLES WITH NONWOVEN SUBSTRATES HAVING FIBRILS
A nonwoven substrate for an absorbent article including a layer of fibers is provided. The nonwoven substrate has a low surface tension fluid strikethrough time to basis weight ratio in the range of about 0.37 s/gsm to about 5 s/gsm. A plurality of the fibers each include fibrils extending outwardly from a surface of the fibers. The plurality of the fibers are made from a composition including a polyolefin and about 11% to about 35% of glycerol tristearate by weight of the composition. The nonwoven substrate has a specific surface area in the range of about 1 m.sup.2/g to about 4 m.sup.2/g.

SLIPPERY LIQUID-INFUSED POROUS SURFACES AND BIOLOGICAL APPLICATIONS THEREOF
A self-healing, scratch resistant slippery surface that is manufactured by wicking a chemically-inert, high-density liquid coating over a roughened solid surface featuring micro and nanoscale topographies is described. Such a slippery surface shows anti-wetting properties, as well as exhibits significant reduction of adhesion of a broad range of biological materials, including particles in suspension or solution. Specifically, the slippery surfaces can be applied to medical devices and equipment to effectively repel biological materials such as blood, and prevent, reduce, or delay coagulation and surface-mediated clot formation. Moreover, the slippery surfaces can be used to prevent fouling by microorganisms such as bacteria.
SANITATION SYSTEMS AND COMPONENTS THEREOF HAVING A SLIPPERY SURFACE
The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). Slippery liquid-infused porous surfaces outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5?), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressures (up to at least 690 atm). Some exemplary application where slippery liquid-infused porous surfaces will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.
