Patent number: 11718629Abstract: This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.Type: GrantFiled: November 18, 2021Date of Patent: August 8, 2023Assignees: Drexel University, The United States of America as Represented by the Secretary of the ArmyInventors: Joshua Matthew Sadler, John Joseph La Scala, Giuseppe R.

Publication number: 20210380567Abstract: A composition of matter including two optionally substituted phenol or optionally substituted aniline units separated by a furan spacer has been prepared. In particular, the chemical structure has a novolac bridge between the central furan ring and the two attached optionally substituted phenol and/or optionally substituted aniline units. These compounds can be modified to be used in various polymer resins. This new structure reduces toxicity relative to BPA/F, makes use of renewable chemicals, and produces certain beneficial polymer properties.Type: ApplicationFiled: October 10, 2019Publication date: December 9, 2021Applicants: Drexel University, The Government of the United States, as represented by the Secretary of the Army, Rowan UniversityInventors: Craig Michael PAQUETTE, John Joseph LA SCALA, Joshua Matthew SADLER, Giuseppe Rafaello PALMESE, Alexander William BASSETT, Joseph Francis STANZIONE

Publication number: 20210077993Abstract: The present invention relates to bio-secure means for the detection of pathogens and provides a bio-secure reaction vessel and methods of preparing a sample for PCR-based pathogen detection. The reaction vessel comprises a reaction chamber portion (1); a cap holder portion (2); and a cap (3). Two points of security, such as two O-ring seals (9, 10), are provided between the cap (3) and the reaction chamber portion (1). A first seal (9) may be located at a top of the cap holder portion (2) and a second seal (10) may be located at a base of the cap (10).Type: ApplicationFiled: April 25, 2019Publication date: March 18, 2021Inventors: Nelson Nazareth, David Edge, Adam Tyler, Matthew Sadler
