A flame-retardant composition is described comprising a mixture of a water dispersible organic polymer; and a water dispersible derivative of an unsaturated dicarboxylic acid or anhydride thereof. The water dispersible derivative typically has a solubility in a 0.1 N aqueous solution of NaOH at 25° C. of at least 25 g/liter. Also described is a flame-retardant composition comprising the mixture described dispersed in an aqueous carrier and method of making a flame-retardant composition.

Provided are acoustic articles having a porous layer () placed in contact with a heterogeneous filler comprising porous carbon and having an average surface area of from 0.1 m/g to 10,000 m/g. The acoustic articles can have a flow resistance of from 10 MKS Rayls to 5000 MKS Rayls. Optionally, the porous layer includes a non-woven fibrous layer or a perforated film having a plurality of apertures with an average narrowest diameter of from 30 micrometers to 5000 micrometers. The heterogeneous filler can enhance low frequency performance without significantly compromising high frequency performance, thickness or weight.

The present invention relates to core shell liquid metal encapsulates comprising and processes of making and using such encapsulates and networks. The shell(s) of such encapsulates employ a palette of materials having widely varied band structures and/or the desired spin pairing and/or bond polarization. Such encapsulates can be designed to respond to one or more stimuli of choice, including but not limited to electromagnetic, thermal, mechanical, photonic, and/or magnetic and are environmentally robust.

Article () comprising a substrate () comprising a polymer and having first () and second () opposed major surfaces. The first major surface () has first surface regions () with first nanoparticles () partially embedded into the first major surface (), and one of &#x2022;(a) second surface regions () free of nanoparticles; or &#x2022;(b) second surface regions () with at least second nanoparticles () on the first major surface () or partially embedded into the first major surface (). The first surface regions () have a first average surface roughness, R, of at least 20 nm, wherein the second surface regions () have a second average surface roughness, R, of less than 100 nm, wherein the first average surface roughness, R, is greater than the second average surface roughness, R, and wherein there is an absolute difference between the first and second average surface roughness of at least 10 nm.
