Filed:

Jan 10, 2011

Appl. No.:

12/987594

Inventors:

Sarah M. Cooper - Santa Clara CA, US
Cathy Fleischer - Rochester NY, US
Michael Duffy - Rochester NY, US
Aaron Wagner - Rochester NY, US

Assignee:

NaturalNano, Inc. - Pittsford NY

International Classification:

C08K 9/04

US Classification:

524445, 524451

Abstract:

Disclosed is a novel polymeric composite including a nanoparticle filler and method for the production thereof. More particularly, the present invention provides a novel halloysite nanoparticle filler which has the generally cylindrical or tubular (e. g. rolled scroll-like shape), in which the mean outer diameter of the filler particle is typically less than about 500 nm. The filler is effectively employed in a polymer composite in which the advantages of the tubular nanoparticle filler are provided (e. g. , reinforcement, flame retardant, chemical agent elution, etc. ) with improved or equivalent mechanical performance of the composite (e. g. , strength and ductility).

US Classification:

508150000, 508551000, 508554000

Abstract:

An indicating lubricant additive comprising a color-changable polymer having an outer layer of a first color, and an intermediate layer of a second color; and a lubricant sensing dipstick comprising a circuit housing, an elongated body having a proximal end and a distal end, and lubricant sensing means disposed at said distal end, wherein in one embodiment, the sensing means detects a change in the indicating lubricant additive that is. present in a lubricant.

International Classification:

A61K 9/14
A61K 8/02

US Classification:

424401000, 424489000

Abstract:

A composition for use in the delivery of a first active agent and a second active agent, the first active agent being sequentially deliverable after the second active agent, the composition comprising hollow mineral microtubules, each of the hollow mineral microtubules having a length, and opposing ends; and including a cylindrical wall, and a hollow lumen; and a central region, an intermediate region, and an outer region along the length; and within the microtubules, the first active agent disposed within the lumen in the central region of the microtubules, and the second active agent disposed within the lumen in the intermediate region of the microtubules. The composition may also be provided for the delivery of three or more active agents in sequence. There is further provided methods for making the compositions of the present invention.
