Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

Advanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Versatile In-Situ Engine Lubricant Health Sensor [PDF]

, 2012
Lubricants which are used in engines to reduce friction, promote engine cooling, and prevent corrosion degrade with time under harsh engine operating conditions and hence need to be changed periodically.

Unidirectional Tape‐Based Composites from Hemp and Pineapple Leaf Fiber: Mechanical Performance in Conventional and Bio‐Based Matrices

Advanced Engineering Materials, EarlyView.
The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.

Changes of engine oil flow properties during its life cycle

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
The work is focused on quantification of influence of operation on flow properties of motorcycle engine oil. Three different kinds of synthetic engine oil (MOTUL) were tested, namely unused oil, run-in oil (650 km after engine reboring) and regular ...

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object

Advanced Engineering Materials, EarlyView.
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

Biological Treatment of Used Engine Oil by Single and Mixed Bacterial Cultures Isolated from Soil of Mechanic Workshops

مجلة مركز بحوث التقنيات الاحيائية, 2018
The accumulation of hydrocarbon waste, such as used engine oils in environments, has many impacts on humans and other organisms, therefore many researches were achieved to degrade or remove or consume these pollutants. The aim of the current study is to
