Method for Reducing or Eliminating the Carry Back of Aggregate Material by Hauling Equipment
A method for reducing aggregate material carry back in aggregate material hauling equipment includes applying an effective amount of an anti-sticking and anti-icing agent to hauling surfaces of the aggregate material hauling equipment that will subsequently be in contact with the aggregate material to be hauled. The method includes initiating loading of the aggregate material into the aggregate material hauling equipment while the hauling surfaces of the hauling equipment remain wet from the applying of the anti-sticking and anti-icing agent. This ensures wetting of the aggregate material at the interface with the hauling surface to provide improved anti-sticking and anti-icing action.
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.
Coating composition and method for the protection of complex metal structures and components used in submerged environments
A coating composition for application to a subsea component or structure includes a cellulose acetate, a plasticizer, a vegetable oil, a colorant, and a titanium dioxide stabilizer that are mixed together. The plasticizer is epoxidized linseed oil. The colorant is carbon black powder. The vegetable oil is selected from the group including vegetable oil and soybean oil.
Coating composition for the protection of complex metal structures and components
A coating composition for application to a component or structure has cellulose acetate, a plasticizer with an antioxidant, a corrosion inhibitor with an antioxidant, a vegetable oil, and a stabilizer. The plasticizer is linseed oil. The corrosion inhibitor is canola oil. The vegetable oil is epoxidized soybean oil. The stabilizer is titanium dioxide. These components are intimately mixed together so as to form a solid mixture. The solid mixture is converted into a solid state and applied to the component or structure. The liquid state is then dried on the component or structure for a period of time.

METHOD FOR PREPARING MULTIFUNCTIONAL ENVIRONMENTAL FRIENDLY COATING FOR WATERPROOF AND OIL-PROOF FOOD PACKAGING PAPERS BY ONE STEP METHOD AND APPLICATION THEREOF
The method of the present invention specifically comprising following steps: adding a chitosan to an acetic acid solution, heating and stirring until clear, to obtain an acidic chitosan solution; then adding a palm wax and heating a resulting mixture to 80-100 C. with a constant temperature and a high-speed stirring for emulsification for 5-15 minutes; after the emulsification is completed, an obtained emulsion is quickly cooled to a room temperature. The present invention uses a single-layer coating method to prepare waterproof and oil-proof food cardboard, simplifying operation and achieving good waterproof, oil-proof, and antibacterial effects with a lower coating amount, thereby reducing production costs. When a coating amount is 5-10 g/m.sup.2, a Cobb.sub.60 value can reach 5-9 g/m.sup.2, an oil resistance level can reach 11-12 levels, a water contact angle can reach over 130, and an antibacterial rate can reach over 90%.
Slippery surfaces with high pressure stability, optical transparency, and self-healing characteristics
The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). 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). SLIPS 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 pressure (up to at least 690 atm).

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.
