Abstract: The system for making suspensions includes a housing, with a platform mounted therein and a translating table slidably mounted on the platform for removably supporting a receptacle. A base fluid tank stores a base fluid, and a solid particle container stores solid particles. A rotating dispenser system is mounted within the housing, above the platform and the receptacle. The rotating dispenser includes a base fluid dispenser for dispensing a controlled mass of the base fluid into the receptacle, and a solid particle dispenser for dispensing a controlled mass of the solid particles into the receptacle. The base fluid dispenser is in communication with the base fluid tank, and the solid particle dispenser is in communication with the solid particle container. A mixer selectively and controllably mixes the controlled mass of the base fluid and the controlled mass of the solid particles in the receptacle to form the suspension.

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.

Abstract: A system and method for producing hydrogen (H2) gas and a magnesium (Mg)-aluminum (Al) based aqueous suspension from pre-prepared effervescent tablets are provided. The produced H2 gas can be stored in a tank or directly utilized in a fuel cell, whereas the produced suspension can be employed as an advanced heat transfer fluid in a variety of thermal applications. Furthermore, the as-prepared tablets are fabricated with a homogeneously mixed and well-compressed mixture of Al particles, Mg particles, and sodium bicarbonate (NaHCO3) powder in a sealed container to prevent air and humidity from reacting with the raw materials. As a result of the chemical reaction between the tablet and water, H2 gas (in the form of bubbles) and the Mg—Al-based suspension are produced simultaneously. This system results in two products (i.e., H2 and suspension) that can be used individually or all at once by integrating the different system components together.

Abstract: A system and method for producing hydrogen (H2) gas and a single or hybrid hydrogen active material based aqueous suspension from pre-prepared effervescent tablets are provided. The produced H2 gas can be stored in a tank or directly utilized in a fuel cell, whereas the produced suspension can be employed as an advanced heat transfer fluid in a variety of thermal applications. The effervescent tablets can be fabricated with a homogeneously mixed and well-compressed mixture of hydrogen active metallic particles and effervescent powder in a sealed container to prevent air and humidity from reacting with the raw materials. As a result of the chemical reaction between the tablet and water, H2 gas (in the form of bubbles) and the hydrogen active material-based suspension are produced simultaneously. This system results in two products that can be used individually or all at once by integrating the different system components together.
