A system includes a curing assembly for low temperature curing and residual stress relief of material substrates. The curing assembly includes a first exposure chamber configured to expose the material substrate to UV radiation, and a second exposure chamber configured to expose the material substrate to Gamma radiation. In some embodiments, a mixing apparatus may mix nano-filler particles into the material substrate prior to exposure to Gamma radiation. The cure assembly may also include a control system for determining exposure dosages and exposure times based at least in part, on the material properties of the material substrate.

Systems and methods for assessing flowability of a multiphase fluid are provided. The method includes agitating a sample of the multiphase fluid contained in a container while controlling an agitation force applied to the sample; pouring the sample, after it has been agitated, into a viscosity cup having an opening at its upper end and an orifice at its lower end and thereby causing the multiphase fluid to flow out of the viscosity cup through the orifice; weighing an amount of the multiphase fluid that has flowed through the orifice and into a receiving vessel over a period of time; and assessing flowability of the multiphase fluid sample using the weight of the multiphase fluid sample in the receiving vessel as a function of time.

A method of detecting at least one contaminant in a flow of a liquid fuel includes measuring one or more parameters of a flow of the liquid fuel. Based on the measured one or more parameters, one or more properties of the liquid fuel are determined. A plurality of features are from selected ones of the one or more parameters and one or more properties. A trained classification model is applied on the extracted features to determine a type and a quantity of at least one contaminant in the liquid fuel.

Provided herein are portable apparatus as well as methods of analyzing a fluid using these portable apparatus. In some embodiments, the injection fluid can contain a polymer, but a polymer is not necessary. For example, the portable apparatus and methods may be used to determine viscosity, long term injectivity, filter ratio, or any combination thereof of the injection fluid. Advantageously, the surrogate core is temperature controlled.
