Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

CO2 Permeability in HNBR: Insights for CO2 Transport Applications

Macromolecular Symposia, EarlyView.
ABSTRACT Carbon capture, utilization, and storage is a crucial short‐term strategy to mitigate climate change. Once captured, CO2 needs to be transported to storage sites, and to ensure efficient transport, it is typically compressed into a liquid or supercritical fluid.

Influence of Velocity Feedback Time Delay on the Nonlinear Dynamic Characteristics of Maglev Trains Under Unsteady Aerodynamic Forces

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...
