Guided analysis of ambient ionization mass spectrometry data with the MQ_Assistant

Rapid Communications in Mass Spectrometry, 2023
RATIONALE Ambient ionization mass spectrometry (AIMS) delivers realistic data from samples in their native state. In addition, AIMS methods reduce time and costs for sample preparation and have less environmental impact. However, AIMS data are often complex and require substantial processing before interpretation.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...
