Abstract: Systems and methods for real-time monitoring of electrical discharge events across a tribological contact are provided. The systems comprise a signal generator, a test device comprising a tribological contact, a reference device and a signal comparator. The systems recognize changes between states where electrical discharge across a tribological contact does or does not occur and produce distinct output signals for each state and, further, may maintain a count of how often such events occur.

Abstract: Described herein are methods of manipulating/tailoring wettability of liquids on physically/chemically modified surfaces under multiphase conditions (i.e. >1 liquid contacting surface). In particular, methods of modifying or tuning the wettability of a surface in multiphase conditions could decelerate corrosion, modify drag in a pipe, and/or enable separation of a two-phase liquid system.
