The Deterioration Mechanism of Diester Aero Lubricating Oil at High Temperature
Journal of Spectroscopy, 2017 The deterioration of aero lubricating oil at high temperatures was accelerated by using a specific device simulating the operating conditions of engines, where the deterioration mechanism was obtained. Structures of the deteriorated lubricating oils were

Advanced Science, EarlyView.This study develops a hierarchically porous hydrogel patch strategy (HPMP), based on gas‐shearing microfluidics and an aqueous two‐phase system to fabricate porous microgels as microgel‐based bioinks. The porous microgels with controllable porous structure exhibit excellent cellular behavior.

Hydrocarbon degradation potentials of bacteria isolated from spent lubricating oil contaminated soil
Journal of Applied Sciences and Environmental Management, 2017 This study investigates the hydrocarbon degradation potentials of some bacteria isolated from spent lubrication oil on contaminated soil. Cleaning up petroleum hydrocarbon contaminated sites has been a major challenge. This has led to the exploration of

Mechanical impact tests of materials in oxygen effects of contamination [PDF]
The effect of contaminants on the mechanical impact sensitivity of Teflon, stainless steel, and aluminum in a high-pressure oxygen environment was investigated. Uncontaminated Teflon did not ignite under the test conditions.

Advanced Science, EarlyView.By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...

Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films
Advanced Science, EarlyView.Inverted liquid films, like paint on a ceiling, are inherently unstable under gravity. This work shows that selective evaporation in volatile binary mixtures generates solutal Marangoni stresses that either suppress or amplify the Rayleigh Taylor instability.

Optimization of Heat Exchanger Design Parameters for Hydrocarbon Refrigerant Systems [PDF]
, 2004 Hydrocarbon refrigerants (HC's) are one alternative to hydrofluorocarbons (HFC???s) since they have zero ozone depletion potential and negligible global warming potential.
