PERFORMED IDENTITIES: HEAVY METAL MUSICIANS BETWEEN 1984 and 1991 Bradley C. Klypchak a Dissertation Submitted to the Graduate
PERFORMED IDENTITIES: HEAVY METAL MUSICIANS BETWEEN 1984 AND 1991 Bradley C. Klypchak A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY May 2007 Committee: Dr. Jeffrey A. Brown, Advisor Dr. John Makay Graduate Faculty Representative Dr. Ron E. Shields Dr. Don McQuarie © 2007 Bradley C. Klypchak All Rights Reserved iii ABSTRACT Dr. Jeffrey A. Brown, Advisor Between 1984 and 1991, heavy metal became one of the most publicly popular and commercially successful rock music subgenres. The focus of this dissertation is to explore the following research questions: How did the subculture of heavy metal music between 1984 and 1991 evolve and what meanings can be derived from this ongoing process? How did the contextual circumstances surrounding heavy metal music during this period impact the performative choices exhibited by artists, and from a position of retrospection, what lasting significance does this particular era of heavy metal merit today? A textual analysis of metal- related materials fostered the development of themes relating to the selective choices made and performances enacted by metal artists. These themes were then considered in terms of gender, sexuality, race, and age constructions as well as the ongoing negotiations of the metal artist within multiple performative realms. Occurring at the juncture of art and commerce, heavy metal music is a purposeful construction. Metal musicians made performative choices for serving particular aims, be it fame, wealth, or art. These same individuals worked within a greater system of influence. Metal bands were the contracted employees of record labels whose own corporate aims needed to be recognized. -

Abstract: Aerospace missions require that pyrotechnic compositions are able to withstand 180 ◦C. Therefore, this paper studies the thermal stability and output performance of boron/potassium nitrate (abbreviated BPN) used in pyrotechnic devices. Firstly, differential scanning calorimetry (DSC) and thermogravimetric (TG) tests are used to analyze the thermal reaction process of KNO3, boron, and BPN to qualitatively judge their thermal stability. Then, apparent morphology analysis, component analysis, and the p-t curve test, which is the closed bomb test to measure the output power of the pyrotechnic composition, are carried out with BPN samples before and after the high-temperature test to verify BPN stability at 180 ◦C. -

As a In a recently published article on the regulatory practical matter, metal oxides are the only pyro- definitions of firework flash powder[1] it was con- technic reaction products that are not gaseous at cluded that none of those definitions provided suf- high temperature. Thus metal fuels need to be pre- ficient information to objectively establish wheth- sent in substantial quantity in flash powders. See er or not a pyrotechnic composition is a flash Table 1, which is a list of the boiling point of powder. That is to say, those definitions are all some of the pyrotechnic reaction products. The subjective to the extent that they depend on the table has somewhat arbitrarily been divided into intended use of the composition and none provide species with boiling points above and below a quantifiable measure that can be used to deter- 2500 °C.

Taming Dinitramide Anions Within an Energetic Metal–Organic Framework
Article pubs.acs.org/cm Taming Dinitramide Anions within an Energetic Metal−Organic Framework: A New Strategy for Synthesis and Tunable Properties of High Energy Materials † † † † ‡ † † Jichuan Zhang, Yao Du, Kai Dong, Hui Su, Shaowen Zhang, Shenghua Li,*, and Siping Pang*, † School of Materials Science & Engineering, Beijing Institute of Technology, Beijing 100081, P. R. China ‡ School of Chemistry, Beijing Institute of Technology, Beijing 100081, P. R. China *S Supporting Information ABSTRACT: Energetic polynitro anions, such as dinitramide − fi fi ion [N(NO2)2 ], have attracted signi cant interest in the eld of energetic materials due to their high densities and rich oxygen contents; however, most of them usually suffer from low stability. Conveniently stabilizing energetic polynitro anions to develop new high energy materials as well as tuning their energetic properties still represent significant challenges. To address these challenges, we herein propose a novel strategy that energetic polynitro anions are encapsulated within energetic cationic metal−organic frameworks (MOFs). We − present N(NO2)2 encapsulated within a three-dimensional (3D) energetic cationic MOF through simple anion exchange. The resultant inclusion complex exhibits a remarkable thermal stability with the onset decomposition temperature of 221 °C, which is, to our knowledge, the highest value known for all dinitramide-based compounds. In addition, it possesses good energetic properties, which can be conveniently tuned by changing the mole ratio of the starting materials. The encapsulated anion can also be released in a controlled fashion without disrupting the framework. This work may shed new insights into the stabilization, storage, and release of labile energetic anions under ambient conditions, while providing a simple and convenient approach for the preparation of new energetic MOFs and the modulation of their energetic properties. -

Notably, graphitic carbon nitride (g-C3N4) is the most stable allotrope of carbon nitrides. It has been explored in various analytical fields due to its excellent biocompatibility properties, including ease of surface functionalization and hydrogen-bonding. Graphitic carbon nitride (g-C3N4) acts as a nanomediator and serves as an immobilization layer to detect various biomolecules. Numerous reports have been presented in the literature on applying graphitic carbon nitride (g-C3N4) for the construction of electrochemical sensors and biosensors. Different electrochemical techniques such as cyclic voltammetry, electrochemiluminescence, electrochemical impedance spectroscopy, square wave anodic stripping voltammetry, and amperometry techniques have been extensively used for the detection of biologic molecules and heavy metals, with high sensitivity and good selectivity. -
