3 results about "Water uptake" patented technology

The portable water harvesting device includes a vacuum-compatible water collection unit and a detachable lid incorporating a metal-organic framework (MOF) unit. The water collection unit comprises a vacuum pump connection port and a drain valve for extracting collected water. The detachable lid contains MOFs in the form of beads or dispersed within a porous medium, encapsulated by a vapor-permeable, MOF-retaining filter membrane. A solar-absorbing metal plate is affixed to the outer surface of the lid to facilitate thermal activation. The lid is removably attached to the collection unit via a screw-type or snap-fit closure, forming an airtight seal during vacuum desorption. Enhanced exposure of MOFs to ambient air improves water uptake, and vacuum-assisted depressurization accelerates desorption. The device is lightweight, power-independent, and suitable for deployment in off-grid or water-scarce environments such as islands, boats, or emergency lifeboats.

The invention relates to curable compositions made of reaction resins, comprising polymerizable functional cyanate ester groups and poly(diorgano)siloxanes with phenolic hydroxy groups; to a method for producing the same; and to cured materials and composites obtainable therefrom and having a low water uptake, a high fracture toughness and a high glass transition temperature.

Irrigation needs assessment systems and methods may determine irrigation needs of one or more participants. The irrigation needs assessment system may determine irrigation needs based on weather conditions, forecast weather conditions, plant water uptake, and ground moisture content information. Evaporation rate information may be provided from one or more other participants of the irrigation needs assessment service.
