Abstract:
An improved oil composition is disclosed. The oil composition includes a base oil comprising a hydrocarbon, the base oil having a base thermal conductivity. The oil composition also includes a first additive comprising a plurality of derivatized first additive nanoparticles dispersed within the base oil to form a modified oil having a modified thermal conductivity, wherein the modified thermal conductivity is greater than the base thermal conductivity. Alternately, an improved oil composition includes a base oil comprising a hydrocarbon and a first additive comprising a plurality of derivatized first additive nanoparticles dispersed within the base oil to form a modified oil comprising a stabilized suspension of the derivatized first additive nanoparticles in the base oil.

Abstract:
The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.

Abstract:
Methods for applying an antimicrobial coating to a medical device is disclosed. Generally, the methods comprise providing a medical device, dispensing an antimicrobial coating onto the device, flushing excess coating from the device, and curing the coating onto the device. In one aspect, the coating includes a UV-curable, antimicrobial composition. In this aspect, the medical device can be coated and the coating can be cured with UV light in a manner of seconds. In another aspect, the coating includes an antimicrobial solution that contains an acrylate-type polymer or copolymer. In this aspect, the medical device can be coated and the coating can be heat-cured in a manner of minutes. Both the UV-curable composition and the antimicrobial solution can also include rheological modifiers, as necessary. Additionally, the compositions include one or more antimicrobial agents, which may be selected from a wide array of agents.
Abstract:
The invention relates to an adhesive thin lubrication composition for covering at least one thread (FI) and a screwing abutment (BVF) of the threaded member (EF) of a component (T1) of a tubular threaded seal (JF). The screwing abutment bears against another abutment (BVM) of another component (T2) of the tubular threaded seal (JF) in the terminal screwing phase. The lubrication composition includes a matrix having dispersed therein at least one braking additive selected in order to impart thereto, and on top of the lubrication, a friction coefficient selected so as to obtain a torque on abutment value at least equal to a threshold value.
Abstract:
Une composition de lubrification adhésive, mince, est destinée à recouvrir au moins un filetage (FI) et une butée de vissage (BVF) d'un élément fileté (EF) de composant (T1) d'un joint fileté tubulaire (JF). La butée de vissage est destinée à s'appuyer contre une autre butée (BVM) d'un autre composant (T2) du joint fileté tubulaire (JF) en phase terminale de vissage. La composition de lubrification comporte une matrice dans laquelle est dispersé au moins un additif de freinage choisi de manière à lui conférer, en complément de la lubrification, un coefficient de frottement choisi pour permettre l'obtention d'une valeur de couple sur butée au moins égale à une valeur seuil.
