Friction and wear are the source of every mechanical device failure, and lubricants are essential for the operation of the devices. These physical phenomena have a complex nature so that no model capable of accurately predicting the behavior of lubricants exists. Thus, lubricants cannot be designed from scratch but have to be screened through expensive trial-error tests. In this study we propos...

Growing demands from industry for the use of eco-friendly lubricants led research towards finding environmentally friendly products with superior lubricating characteristics. Vegetable oils and synthetic ester oils are competitive base oils used to obtain lubricants with good physico-chemical, rheological and tribotechnical properties, biodegradable lubricants without negative environmental imp...

PURPOSE: The purpose of this study is to provide a preliminary assessment of Environmentally Acceptable Lubricants (EALs) for application in dams that are managed by the U.S. Army Corps of Engineers (USACE). The assessment will explore the environmental aspects of these lubricants and will also discuss their operational characteristics. This assessment is primarily through the literature availa...

Development and application of biocompatible lubricants are increasing daily as a result of stringent regulations imposed on mineral oil-based lubricants with their non-biodegradable toxic wastes. Before consumer acceptance of vegetable oil-based lubricants, they must overcome certain poor performance characteristics such as thermal and oxidative instabilities. This work demonstrates the improv...

In many cases, especially those involving sexual assault, forensic scientists are searching the biological evidences such as blood, skin, hair, saliva, urine, semen for DNA analysis. Recently, the uses of condoms in sexual assault cases were increasing to avoid leaving the biological traces in the crime scene. In these cases, finding the condom lubricant traces from the victims can be valuable ...

There is a need to improve conventional polyolester lubricants that are currently being evaluated as the optimal refrigeration base oil for the alternative refrigerants R41 OA and R407C, which are expected to be designated as the replacement ofHCFC 22. Prior studies show that the conventional polyolesters and other lubricants have poor hydrolysis and solubility. This paper is an introduction to...
