Regeneration of used lubricating oil as a source of energy

open access: yesArid Zone Journal of Engineering, Technology and Environment, 2001
Conservation of natural resources by refining used lubricating oil was attempted in this work. Used lubricating oil was purified and distilled. The distillates obtained were divided into two temperature ranges of 60 - 210°C and 210 - 310°C.

Synthetic lubricants and lubricating oil additives.

open access: yesJournal of The Japan Petroleum Institute, 1988
著者が行ってきた合成潤滑油および添加剤の研究を紹介する。1)ポリオールエステル2種類の混合基油を用いて高温安定性のすぐれた7808Fグレードジェットエンジン油を開発した。2)2-エチルヘキサノール製造時に副生するC16エーテルは高粘度指数作動油の基油としてすぐれている。3)ポリC1~C4アルキルメタクリレートは芳香族りん酸エステルに可溶であり, 粘度指数向上効果をもつ。4)チオりん酸亜鉛とアミンとは錯体をつくる。錯体は4種類ある。油中で解離平衡状態にあり, 解離度はアミンの立体障害と塩基度により決まる。錯体の合潤中での耐摩耗性はその熱安定性よりも金属表面への吸着性に支配される。

Characterization of Fatty Acid Profiles and Nutritional Quality Indices in Commercial Spreadable Processed Cheeses: Comparative Analysis and Health Implications

open access: yesFood Safety and Health, EarlyView.
Natural processed cheeses showed a more favorable nutritional profile, including higher unsaturated fatty acids and better functional performance. A balanced fatty acid composition was identified as a key factor influencing meltability, oil separation, and overall quality of processed cheeses.

Cobalt‐Doped Diamond‐Like Carbon Coatings Combined With Functionalised Polymers for Enhanced Tribological Performance

open access: yesLubrication Science, EarlyView.
ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

open access: yesLubrication Science, EarlyView.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Electrochemical Monitoring of Steel Corrosion in NS4 Solution Under Cathodic Protection Environment: Insights of Electrochemical Impedance Spectroscopy

open access: yesMaterials and Corrosion, EarlyView.
Electrochemical impedance spectroscopy (EIS) monitored corrosion on mild steel under cathodic protection in soil‐like conditions. CP reduced corrosion from 410 to 7 µm/yr, shifting the mechanism from mixed activation–diffusion to activation‐controlled, enabling protective calcareous and oxide film formation.
