In a method of analyzing solid form properties of a substance, which including the step of solidifying the substance, the solidified substance is obtained in one of a plurality of wells of a multi-well plate. In the multi-well plate the at least one of the plurality of wells has a bottom made of a thermoplastic polyimide. The method further includes analyzing the solidified substance in the well of the multi-well plate by X-ray diffraction. Thereby, the analysis includes providing X-ray through the solidified substance and a bottom of the well and evaluating the X-ray which passed the solidified substance and the bottom of the well. Such method and multi-well plate provide a durable and cost efficient system allowing a high quality analysis of solid form properties of the substance and an efficient and safe processing of the substance.

Microfluidic structures and methods for manipulating fluids and reactions are provided. Such structures and methods may involve positioning fluid samples, e.g., in the form of droplets, in a carrier fluid (e.g., an oil, which may be immiscible with the fluid sample) in predetermined regions in a microfluidic network. In some embodiments, positioning of the droplets can take place in the order in which they are introduced into the microfluidic network (e.g., sequentially) without significant physical contact between the droplets. Because of the little or no contact between the droplets, there may be little or no coalescence between the droplets. Accordingly, in some such embodiments, surfactants are not required in either the fluid sample or the carrier fluid to prevent coalescence of the droplets. Structures and methods described herein also enable droplets to be removed sequentially from the predetermined regions.

An integrated hydrothermal process for upgrading heavy oil includes the steps of mixing a heated water stream and a heated feed in a mixer to produce a mixed fluid, introducing the mixed stream to a reactor unit to produce a reactor effluent that includes light fractions, heavy fractions, and water, cooling the reactor effluent in a cooling device to produce a cooled fluid, depressurizing the cooled fluid in a depressurizing device to produce a depressurized fluid, introducing the depressurized fluid to a flash drum configured to separate the depressurized fluid into a light fraction stream and a heavy fraction stream. The light fraction stream includes the light fractions and water and the heavy fraction stream includes the heavy fractions and water. The process further includes the step of introducing the heavy fraction stream to an aqueous reforming unit that includes a catalyst to produce an aqueous reforming outlet.

A method and a system for resolving a crystal structure of a crystal at atomic resolution by collecting X-ray diffraction images. The method includes the steps: a) ejecting a droplet of fluid comprising single or multiple of crystal into an ultrasonic acoustic levitator; b) levitating the droplet of fluid with the crystal in the ultrasonic acoustic levitator; b) monitoring the position and the spinning of the droplet with a visualization apparatus; c) applying X-ray to the crystal, the X-ray stemming from an X-ray source; and d) detecting the X-ray diffraction images from the crystal irradiated by the X-ray source by an X-ray detector being capable to capture two dimensional diffraction patterns.
