A lubricating oil composition comprises an amide and at least one additive. A lubricating grease composition comprises a liquid amide, a thickener comprising a metal soap, and at least one additive. The amide in each composition is the reaction product of a secondary, branched amine and a carboxylic acid. The carboxylic acid may be a monocarboxylic acid or a dicarboxylic acid, including dimer acid. The amide is hydrolytically stable, and may be used to increase the hydrolytic stability of the lubricant oil or grease composition. Alternatively, the amide may be used to increase the additive solubility or detergency of the lubricant oil or grease composition.

Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressure (up to at least 690 atm). Some exemplary application where SLIPS will be useful include energy-efficient fluid handling and transporation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating environments. 1. An article having a repellant surface , the article comprising:a substrate comprising a roughened surface; anda lubricating liquid wetting and adhering to the roughened surface to form a stabilized liquid overlayer, wherein the liquid covers the roughened surface at a thickness sufficient to form a liquid upper surface above the roughened surface,wherein the roughened surface and the lubricating liquid have an affinity for each other such that the lubricating liquid is substantially immobilized on the substrate to form a repellent surface.284.-.

A heat treatment oil composition is provided that suppresses the decrease of luster in a heat treatment of a metal material, and is capable of suppressing the increase of the number of second (characteristic number of second) until reaching the temperature where the vapor blanket stage ends with the lapse of time and the decrease of the kinetic viscosity with the lapse of time. The heat treatment oil composition contains (A) a base oil and (B) a vapor blanket breaking agent selected from one or more of a petroleum resin, a terpene resin, rosin, and derivatives thereof. 1. A heat treatment oil composition , comprising(A) a base oil, and(B) at least one vapor blanket breaking agent selected from the group consisting of a petroleum resin, a terpene resin, a rosin, and derivatives thereof.2. The heat treatment oil composition according to claim 1 , wherein the vapor blanket breaking agent as the component (B) has a softening point measured by the ring and ball method of JIS K2207:2006 of 40° C. or more.3.
