    Abstract: A water desalination system and process are provided in which a suspension is fed into a water desalination chamber from a source container. At least one effervescent tablet is introduced into a base fluid within the source container to form the suspension. The effervescent tablet serves to increase the heat absorption of the base fluid and enhance the efficiency of the water desalination process. The effervescent tablet used in the process may include multi-walled carbon nanotubes (MWCNT) as well as one or more surfactants and/or effervescent agents such as sodium dodecyl sulfate, monosodium phosphate, and sodium carbonate. Introduction of the effervescent tablet into the base fluid may result in the growth of crystals within the suspension. The presence of crystals in the suspension serving to further enhance the solar radiation and heat absorbance of the base fluid.

    Abstract: A sample observation container and methods of use thereof are provided. The sample observation container includes a base and one or more sidewalls extending from the base. The one or more sidewalls form a sample enclosure for holding a sample undergoing a sample observation test such as sedimentation photographical capturing and dynamic light scattering, among other tests. The one or more sidewalls form a sample enclosure of adjustable cross-sectional area. The cross-sectional area may be adjusted by feeding or retracting a flexible sheet from a source roll to the sample enclosure. The cross-sectional area may further be adjusted by removing an innermost sidewall from among one or more nested sidewalls. The containers allow for physical adjustment of the cross-sectional area while performing subsequent sample observation tests, thereby allowing assessment of the effects of container size on the results of the sample, such as particles in liquid suspension.
