Autor: Perrin J. Storch, Michael D. Garrison, Patrick W. Fedick, Valerie H. Adams, William S. Eck, Benjamin G. Harvey

Publikováno v: Green Chemistry. 23:8016-8029

Bisphenol A (BPA) is a versatile petrochemical used in the preparation of high volume polymers including polycarbonates and epoxy resins. Unfortunately, BPA is also an endocrine disrupter and has been banned from use in various consumer products by s

Performance of W/MnO2 as an Environmentally Friendly Energetic Time Delay Composition

Autor: Anthony P. Shaw, Joshua T. Koenig, William S. Eck, Lori J. Groven, Jay C. Poret

Publikováno v: ACS Sustainable Chemistry & Engineering. 5:9477-9484

Current fielded delay formulations face increased scrutiny due to their environmentally hazardous components (i.e., BaCrO4/KClO4), and there is an immediate need for viable replacements. In this work, the W/MnO2 composition is explored as an environm

Effects of 3-Nitro-1,2,4-triazol-5-one on Survival, Growth and Metamorphosis in the Northern Leopard Frog, Lithobates pipiens

Autor: David A. Pillard, Mark S. Johnson, William S. Eck, Stephanie Packard

Publikováno v: Ecotoxicology. 26:1170-1180

New explosive formulations are being developed to be less sensitive to impact and inadvertent explosion, increasing safety for the warfighter. Since testing and training make environmental releases imminent, the toxicity of 3-nitro-1,2,4-triazol-5-on

Synthesis and characterization of a high temperature thermosetting polyimide oligomer derived from a non-toxic, sustainable bisaniline

Autor: Benjamin G. Harvey, Matthew C. Davis, Jason T. Lamb, Michael D. Garrison, Gregory R. Yandek, William S. Eck

Publikováno v: RSC Advances. 7:23149-23156

PMR-15 is a high temperature thermosetting polyimide oligomer widely used in aircraft engines, rocket casings, bushings, and bearings. Unfortunately, PMR-15 is prepared from the mutagenic and hepatotoxic compound methylene dianiline (MDA). To develop

Publikováno v: Regul Toxicol Pharmacol

Perchlorate is an important oxidizer used in propellants, pyrotechnics, and as a gas generator in commercial airbags, fireworks, and roadside flares. It is highly water soluble, interferes with thyroidal iodide uptake and is an environmental contamin

Toxicity of Insensitive Munition (IMX) Formulations and Components

Autor: Mark S. Johnson, William S. Eck, Emily May Lent

Publikováno v: Propellants, Explosives, Pyrotechnics. 42:9-16

New insensitive munitions are being developed to minimize the acute hazards associated with non-intentional detonation of warheads. Two components often used in munition formulations have limited toxicity data, i.e., 3-nitro-1,2,4-triazol-5-one (NTO)

Periodates as Potential Replacements for Perchlorates in Pyrotechnic Compositions

Autor: Jared D. Moretti, William S. Eck, Anthony P. Shaw, Jason S. Brusnahan

Publikováno v: Propellants, Explosives, Pyrotechnics. 42:62-70

The periodate salts NaIO4 and KIO4 are critically evaluated as potential replacements for KClO4 in pyrotechnic compositions. Key differences between the physical and chemical properties of the periodate and perchlorate oxidizers are presented. The th
