Disclosed are of the protected photoinitiators of the formula: wherein Aryl1 is an aromatic or heteroaromatic ring; Aryl2 is an aromatic ring; each Ris an alkyl, an aryl, an electron donating group or an electron withdrawing group, and subscript a is 0 to 3; each Ris an alkyl, an aryl, an electron donating group or an electron withdrawing group, and subscript b is 0 to 3; Prot is a protected carbonyl group. 

Photoinitiators with protected carbonyl group

Described herein is a composition, article and method thereof, wherein the composition comprises (i) a fluoropolymer and (ii) an ionic liquid.

Fluoropolymer blend and articles thereof

Compounds are provided that are either fluorogenic or fluorophoric. Compositions and articles that include the compounds are also provided. Additionally, methods of detecting a microorganism using the compounds are provided. The compounds are fluorinated and can be used advantageously under acidic conditions.

Fluorogenic or fluorophoric compounds and uses thereof

A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than &#x2212;7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of &#x2212;7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than &#x2212;7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles.

Method of making electret articles based on zeta potential

Polycarbonate articles and adhesive composition therefor

An article is disclosed that includes a) a first polycarbonate substrate; b) a second polycarbonate substrate; and c) an adhesive composition disposed between the first polycarbonate substrate and the second polycarbonate substrate such that the first polycarbonate substrate is bonded to said second polycarbonate substrate through the adhesive composition; the adhesive composition includes an adhesive polymer that includes the reaction product of 1) an N-vinyl containing monomer selected from the group consisting of N-vinyl caprolactam, N-vinyl pyrrolidone, and N-vinyl imidazole, and combinations thereof, and 2) an acrylic acid ester monomer of a non-tertiary alcohol having an alkyl group that includes 4 to 20 carbon atoms.

A fluorescent ionophoric compound is disclosed that includes a complexing moiety, such as a cryptand or crown-ether portion, and a fluorescing moiety such as a coumarin portion. The coumarin portion may be substituted at the 3-position with an electron withdrawing or polarizable group such as a substituted aromatic group or a substituted heterocyclic group having a heteroatom in at least one of its alpha positions. The compound, which exhibits good photostability, can be incorporated into cation-sensing composite structures by means of convenient points of covalent attachment.
