Epub 2015 Jan 27. Reversible optical control of conjugated polymer solubility with sub-micrometer resolution Ian E Jacobs 1 , Jun Li, Stephanie L Burg, David J Bilsky, Brandon T Rotondo, Matthew P Augustine, Pieter Stroeve, Adam J Moulé Organic electronics promise to provide flexible, large-area circuitry such as photovoltaics, displays, and light emitting diodes that can be fabricated inexpensively from solutions. A major obstacle to this vision is that most conjugated organic materials are miscible, making solution-based fabrication of multilayer or micro- to nanoscale patterned films problematic. Here we demonstrate that the solubility of prototypical conductive polymer poly(3-hexylthiophene) (P3HT) can be reversibly "switched off" using high electron affinity molecular dopants, then later recovered with light or a suitable dedoping solution. Using this technique, we are able to stack mutually soluble materials and laterally pattern polymer films by evaporation or with light, achieving sub-micrometer, optically limited feature sizes. After forming these structures, the films can be dedoped without disrupting the patterned features; dedoped films have identical optical characteristics, charge carrier mobilities, and NMR spectra as as-cast P3HT films. This method greatly simplifies solution-based device fabrication, is easily adaptable to current manufacturing workflows, and is potentially generalizable to other classes of materials.
Sep 5, 2023 ... Rita Rotondo Obituary Rita Johanna Rotondo, aged 76, of Myrtle ... Rita's love was unconditional, especially towards her sons, David J. Burroughs Funeral Home & Cremation Services Obituary published on Legacy.com by Burroughs Funeral Home & Cremation Services on Sep. 5, 2023. Rita Johanna Rotondo, aged 76, of Myrtle Beach, formerly of McKeesport, PA, Akron, OH, and Pawleys Island, SC, passed away peacefully on Saturday morning, September 2, surrounded by her sons and faithful canine companion, Bella. Born on October 19, 1946, in McKeesport, PA to Goldie Horvatin, Rita was a woman of resilient spirit and endless love. Her life was a tapestry of cherished moments, woven with the threads of family memories, quiet acts of kindness, and her enduring love for Disney. She took immense pleasure in revisiting the classic Disney show, Davy Crockett, a favorite from her childhood, and later enjoyed the magic of Disney World, sharing its wonder with her family. Rita's love was unconditional, especially towards her sons, David J. Smith, Ryan W. Rotondo, and Robin D. Rotondo. She was a widow, having lost her loving husband, Robert Rotondo, in 2000. Throughout her life, she embraced Rob and Renee Rotondo as her stepchildren, reflecting her generous heart. Her granddaughters, Rhea Rotondo, 3, Ashlyn Smith, 14, and Raina Rotondo, 25, were recipients of Rita's boundless love and kindness. They, along with countless others, were touched by Rita's gentle heart, her skill in cross stitch, and the joy she found in the festive spirit of Christmas and her treasured ornament collection. Her brothers, David and Wayne Horvatin, who preceded her in death, shared in her journey, forming bonds that remained strong till the end.

Evidence, Consciousness of guilt, Certificate of drug analysis. INDICTMENT found and returned in the Superior Court Department on June 25, 2001. A pretrial motion to suppress evidence was heard by Charles J. Hely, J., and the case was tried before Linda E. Giles, J. David J. Rotondo for the defendant. Audrey Anderson Kachour, Assistant District Attorney, for the Commonwealth. The defendant, Mario M. Perez, was convicted by a Superior Court jury in July, 2004, of trafficking in cocaine between twenty-eight and one hundred grams, G. L. c. 94C, § 32E(b)(2). [Note 1] He appeals, claiming that (1) his motion for a required finding of not guilty was improperly denied; (2) his pretrial motion to suppress evidence was improperly denied; and (3) his confrontation rights under the Sixth Amendment to the United States Constitution were violated by the introduction of drug analysis certificates without the testimony of the analysts, or an opportunity to cross-examine them. Background. On February 23, 2001, Brockton and State police executed a search warrant for the first-floor apartment of a two-family dwelling that had been under surveillance for a few weeks. In anticipation of executing the warrant, several police officers parked across the street from the house; they saw the defendant and a woman park in front of the house and then walk in the front entrance. About ten minutes later, the defendant came through a door on the driveway side of the house, went down the stairs, moved to one side, and bent over. A fence precluded the police from further view of the defendant. Shortly thereafter, the defendant saw the police and fled into the house, throwing something. The order to execute the warrant was given, and the police entered the house. They found the defendant in a bedroom stuffing objects in his mouth, attempting to swallow them.
