Embodiments in accordance with the present invention encompass compositions containing a latent organo-ruthenium carbide catalyst, a photoactive acid generator or a thermally active acid generator and a photoactive compound along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is exposed to a suitable radiation (or heat) to form a three-dimensional (3D) object. The three-dimensional objects made by this process exhibits improved mechanical properties, particularly, high distortion temperature, impact strength, elongation to break, among others. Accordingly, compositions of this invention are useful as 3D inkjet materials for forming high impact strength objects of various sizes with microscale features lower than 100 microns, among various other uses.

This invention relates to compositions of conducting polymers and their producing methods and applications in sensing technology. The present conducting polymer comprises an electron deficient and an electron rich building block in an alternated repeating unit which can function as sensors to detect, qualify or quantify analytes in fluid and exhibit chemiresistive property and stable performance in normal room temperature and air pressure. In one embodiment, the present invention provides compositions of conducting polymers and devices comprising the present compositions or conducting polymers for sensor application. In another embodiment, the present invention provides methods of detecting target molecules using compositions, conducting polymers or devices of the present invention. The target molecules include without limitation volatile organic compounds (VOCs) which are indicative of the presence or stage or a disease, or indicative of a health status of a subject.
