Tribological Properties of Oil-in-Water Emulsion with Carbon Nanocapsule Additives

Effect of Irradiated Gum Tragacanth on Rheological Properties of Oil in Water Emulsion

Background: Emulsions are thermodynamically unstable systems that can be kinetically stable by adding substances known as emulsifiers and/or thickening agents. By respect to the functional properties of gum tragacanth (GT), and its breakage probability during irradiation treatment, the major aim of this study was to investigate the stability of oil in water emulsion in the presence of different...

Combustion of Water-in-Oil Emulsion Layers Supported on Water

In situ combustion of a water-in-oil emulsion layer supported on water is a complex process. In this paper, the combustion process of water-in-oil emulsion layers floating on top of a water body, as in the case of in situ burning of oil spilled at sea that has turned into emulsion, is modeled by using comprehensive mathematical treatment, and the results are compared with data obtained in our l...

Tribological Properties of Polytetrafluoroethylene, Nano-Titanium Dioxide, and Nano-Silicon Dioxide as Additives in Mixed Oil-Based Titanium Complex Grease

Eight titanium complex greases (i.e., benzoic acid/stearic acid and sebacic acid/stearic acid titanium complex greases, and greases containing PTFE, or nanotitanium dioxide, or nano-silicon dioxide) were synthesized using 3-L reaction vessel. Their physical characteristics were characterized and their tribological properties were evaluated by using a four-ball tester. Chemical compositions of t...

Effects of Chemical Properties of Oil in Water Emulsion on Lipid Peroxidation

Layered Double Hydroxide Nanoplatelets with Excellent Tribological Properties under High Contact Pressure as Water-Based Lubricant Additives.

High efficient and sustainable utilization of water-based lubricant is essential for saving energy. In this paper, a kind of layered double hydroxide (LDH) nanoplatelets is synthesized and well dispersed in water due to the surface modification with oleylamine. The excellent tribological properties of the oleylamine-modified Ni-Al LDH (NiAl-LDH/OAm) nanoplatelets as water-based lubricant additi...
