Abstract: A system for control of optical properties of light comprises a cell comprising a first optically transparent member and a second optically transparent member. The members are disposed in a vertical direction, parallel to each other and at a distance from each other with closed edges, thereby defining a space therebetween. A first fluid is configured to be received within the space. A second fluid, different from the first fluid, is configured to be received into the space, while at least a portion of the first fluid is disposed in the space, causing the first fluid to be displaced. The first and second fluid interface with each other, while remaining separate. The second fluid is configured to be withdrawn from the space leaving the first fluid in the space.

Abstract: The present disclosure describes a strategy to create self-healing, slippery self-lubricating polymers. Lubricating liquids with affinities to polymers can be utilized to get absorbed within the polymer and form a lubricant layer (of the lubricating liquid) on the polymer. The lubricant layer can repel a wide range of materials, including simple and complex fluids (water, hydrocarbons, crude oil and bodily fluids), restore liquid-repellency after physical damage, and resist ice, microorganisms and insects adhesion. Some exemplary applications where self-lubricating polymers will be useful include energy-efficient, friction-reduction fluid handling and transportation, medical devices, anti-icing, optical sensing, and as self-cleaning, and anti-fouling materials operating in extreme environments.

Abstract: 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.

Abstract: A three-dimensional porous photonic structure, whose internal pore surfaces can be provided with desired surface properties in a spatially selective manner with arbitrary patterns, and methods for making the same are described. When exposed to a fluid (e.g., via immersion or wicking), the fluid can selectively penetrate the regions of the structure with compatible surface properties. Broad applications, for example in security, encryption and document authentication, as well as in areas such as simple microfluidics and diagnostics, are anticipated.

Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS) that can be modified as desired. 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 objects, referred to herein as Object A (Solid A or Liquid A). Use of an external stimuli or degradation of the Liquid B can be utilized to change the characteristics of SLIPS structures reversibly or irreversibly that may be desired in a number of different applications. Numerous characteristics, such as adhesion, optical, mechanical, and the like, can be dynamically changed.

Abstract: The present application describes dynamic light control system that, can dynamically adapt to different sun positions and interior lighting levels. The dynamic light control system, includes two or more confinement panes and one or more light redirecting elements positioned therebetween. The light redirecting elements are arranged to deform the light redirecting elements in response to a change in the position of the sun. In addition, one or more fluidic-channels are formed between the light redirecting elements and the confinement panels, that can be filled with any desired fluid to provide additional dynamic changes depending on the desired characteristics.
