摘要:
Embodiments of the present disclosure include compositions for enhanced oil recovery and methods of using the same. Compositions of the present disclosure include particles of a hydrophobic polymer having constitutional repeating units of which at least 10 percent are hydrolysable and through hydrolysis increase a viscosity of the aqueous composition within a subterranean formation.
摘要:
A scientific instrument emulator is disclosed and comprises a computer (1) including a memory (3) and at least two processors (2,9). An analogue I/O module (6) is configured within the computer (1) and connects via a bus (11) thereby permitting conversion of analogue signals into digital signals for processing by the processors (9). The module (6) permits connection to monitoring and/or sampling devices such as transducers which permit analysis and recording of physical phenomena. The emulator is programmable via a library of processing functions stored in the memory (3) to adapt the processors (9) to emulate the operation of a plurality of scientific instruments thereby permitting display of monitored events on a VDU (10) in real-time and/or storage of data relating to the events in the memory (3). Data can also be recorded in analogue format using one or more tape recoders connectable to the module (6).
摘要:
Embodiments of the present disclosure include organic polymeric particles, paper coating compositions, coated paper, and methods of forming coated paper with the paper coating compositions. The embodiments of the organic polymeric particle include an organic hydrophilic polymer with a unit for hydrogen bonding, and a hollow porous structure that comprises an organic polymer that at least partially surrounds the organic hydrophilic polymer, where the hollow porous structure has a pore surface area greater than 1 percent of a total theoretical exterior surface area of the hollow porous structure and the organic hydrophilic polymer and the hollow porous structure give the organic polymeric particle a void volume fraction of 40 percent to 85 percent.
