摘要： Methods related to forming reaction products on surfaces are generally provided. Some methods comprise applying first and second polyelectrolytes in first and second polyelectrolyte carrier fluids to a surface. The first and second polyelectrolytes may be different, and the first and second carrier fluids may be the same or different. Some methods comprise forming a mixture of the first and second polyelectrolytes in a mixture carrier fluid that comprises the first and/or second carrier fluids. The first and second polyelectrolyte may be removed from the mixture carrier fluid to form a reaction product on the surface. In some embodiments, the mixture carrier fluid comprises a salt with a molecular weight of less than or equal to 1 kg/mol at a concentration within the mixture carrier fluid of from 0.01 M to 0.5 M. In some embodiments, the mixture carrier fluid has a turbidity of greater than or equal to 10 NTU and a viscosity of less than or equal to 1 Pa*s.

摘要： Systems and methods related to the formation of a reaction product on a surface are generally provided. The systems and methods described herein may allow for collection of the retention of a fluid by a surface in a relatively high amount. Such systems and methods may be useful in various applications including, for example, agriculture. In some embodiments, the systems and methods enhance water retention on hydrophobic surfaces of plants. Advantageously, the methods described herein may, in some cases, result in the formation of reaction products on a surface that serve to prevent fluids from being removed from the surface. Advantageously, the systems and methods described herein may suppress the adverse effects of natural conditions such as high surface energies and wind.

摘要： Systems and methods related to the collection of a species from a gas stream are generally provided. The systems and methods described herein may allow for collection of a species such as a fluid (e.g., water) with a relatively high collection efficiency. Such systems and methods may be useful in various applications including, for example, fog collection. In some embodiments, the systems and methods enhance water collection from airborne fog to produce usable water. Advantageously, the methods described herein may, in some cases, incorporate ions into the gas stream such that the species present in the gas stream follows electric field lines and/or are attracted to a grounded (or charged) collector. Advantageously, the systems and methods described herein may suppress the adverse effects of natural conditions such as the velocity and direction of the wind.
摘要翻译：通常提供与从气流中收集物种相关的系统和方法。本文描述的系统和方法可以允许以相对高的收集效率收集诸如流体（例如水）的物质。这种系统和方法可用于各种应用，包括例如雾收集。在一些实施例中，系统和方法增强了从空中雾中的水收集以产生可用的水。有利地，在一些情况下，本文所述的方法可以将离子并入气流中，使得存在于气流中的物质遵循电场线和/或被吸引到接地（或带电）的收集器。有利地，本文所述的系统和方法可以抑制诸如风速和风向的自然条件的不利影响。
