Enhancing the Performance of Viscous Electrode-Based Flow Batteries Using Lubricant-Impregnated Surfaces by Solomon, Brian Richmond, Chen, Xinwei, Rapoport, Leonid, Helal, Ahmed H., McKinley, Gareth H, Chiang, Yet-Ming, Varanasi, Kripa

“…Nonaqueous electrochemical couples offer higher cell voltages and higher energy densities and can reduce system-level costs but tend toward higher viscosities and can exhibit non-Newtonian rheology that increases the power required to drive flow. This work uses lubricant-impregnated surfaces (LIS) to promote flow in electrochemical systems and outlines their design based on interfacial thermodynamics and electrochemical stability. …”

Modeling the Fatigue Wear of the Cylinder Liner in Internal Combustion Engines during the Break-In Period and Its Impact on Piston Ring Lubrication by Gu, Chongjie, Wang, Renze, Tian, Tian

“…This work is the first step toward the development of a physics-based liner wear model to predict the evolution of liner roughness and ring pack lubrication during the break-in period. Two major mechanisms are involved in the wear model: plastic deformation and asperity fatigue. …”

Implications of the Use of Biodiesel on the Longevity and Operation of Particle Filters by Kamp, Carl Justin, Bagi, Sujay Dilip

“…The biodiesel-related Na-ash was found to (1) have a significantly lower melting temperature than typical ash from inorganic lubricant additives and Ultra Low Sulfur Diesel (ULSD) fuel resulting in ash particles sintered to the DPF catalyst/substrate, (2) have a primary particle size which is about an order of magnitude larger than typical ash, (3) produce a larger amount of ash resulting in significantly thick wall ash layers and (4) penetrate the DPF substrate about 3× deeper than typical ULSD and lubricant-related ash. …”

Implications of Hydrated Ash on Filtration Efficiency and Performance of Particulate Filters (DPF, GPF, and SCRF)—a Perspective by Bagi, Sujay, Kamp, Carl Justin

“…In most cases, CaSO4 originating from detergent formulations in the lubricant forms the major component of inorganic ash; CaSO4 undergoes hydration cycles forming gypsum, along with semi-/hemi-hydrates through a series of transformations that are a function of temperature, time, and humidity. …”
