Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications
Mass Spectrometry Reviews, EarlyView.ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Virtual Elastic Tether: A New Approach for Multi‐Agent Navigation in Confined Aquatic Environments
Journal of Field Robotics, EarlyView.ABSTRACT Underwater navigation is a challenging area in the field of mobile robotics due to inherent constraints in self‐localization and communication in underwater environments. Some of these challenges can be mitigated by using collaborative multi‐agent teams.

High Voltage, EarlyView.ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...
