Mosbacher, ScK:retary NATIONAL INSrmJTE OF STANDARDS AND TECHNOLOGY John W. Lyons, Director ABSTRACT The use of seismic isolation bearings to decouple buildings and lifeline structures from strong ground motion has received an increased amount of attention in recent years. While several types of seismic isolation bearings have been developed and proposed for use, the most common type is the laminated rubber (elastomeric) bearing. Because the design lifetime of these bearings is expected to be on the order of 50 to 100 years, the long-term performance of the rubber must be addressed. Therefore, a literature review was conducted to identify potential limits on the long-term performance of rubbers used in bearings. Several issues, including the need for consensus performance standards and for additional research on the effects of creep, aging, temperature, and high-energy radiation on the properties of rubber, were identified. -
Exxon™ Butyl Rubber Innertube Technology Manual
Exxon™ butyl rubber Exxon™ butyl rubber innertube technology manual Country name(s) 2 - Exxon™ butyl rubber innertube technology manual Exxon™ butyl rubber innertube technology manual - 3 Abstract Many bias and radial tires have innertubes. Radial truck tube-type tires are particularly common, and in many instances, such as in severe service, off-road applications, are preferred over tubeless radial tire constructions. The technology requirements for tubes for such tires is, in many respects, equally demanding when compared to that for the tire and wheel in the assembly. This manual has been prepared to describe how butyl rubber is important in meeting the demanding performance requirements of tire innertubes. Representative innertube compound formulations and compound properties are discussed along with typical processing guidelines of the compound in the manufacture of innertubes. Chlorobutyl rubber based compound formulations are also used in innertubes. Such innertubes show good heat resistance, durability, allow greater flexibility in compounding, and process equally well as regular butyl rubber tube compounds. An extensive discussion of bicycle tire innertubes has been included. Service conditions can range from simple commuting and recreation to high speed competitive sporting applications. Like automobile and truck tire innertubes, tubes for bicycle tires can thus have demanding performance requirements. Guidelines on troubleshooting provide a checklist for the factory process engineer to enhance manufacturing efficiency, high -

Sponsor: Oklahoma Center for Advancement of Science and Technology PI/PD: Allen Apblett Development of Nanoparticulate Vanadium Bronzes for Detection of Peroxides and Improvised Explosives Explosives pose a deadly risk as a consequence of intentional use by terrorists and accidental detonation resulting from mishandling of explosives, discharge of unexploded ordinance, or even buildup of peroxides in otherwise safe solvents. While there are a large number of sensor technologies for explosives, there is a significant shortfall in ones that can detect improvised explosives such as peroxide-based explosives. Materials that react with these types of explosives to give a dramatic change in color are being used to develop sensor technologies that can protect our society from the threat of explosives.

The Formation of Temporary Communities in Anime Fandom: a Story of Bottom-Up Globalization ______
THE FORMATION OF TEMPORARY COMMUNITIES IN ANIME FANDOM: A STORY OF BOTTOM-UP GLOBALIZATION ____________________________________ A Thesis Presented to the Faculty of California State University, Fullerton ____________________________________ In Partial Fulfillment of the Requirements for the Degree Master of Arts in Geography ____________________________________ By Cynthia R. Davis Thesis Committee Approval: Mark Drayse, Department of Geography & the Environment, Chair Jonathan Taylor, Department of Geography & the Environment Zia Salim, Department of Geography & the Environment Summer, 2017 ABSTRACT Japanese animation, commonly referred to as anime, has earned a strong foothold in the American entertainment industry over the last few decades. Anime is known by many to be a more mature option for animation fans since Western animation has typically been sanitized to be “kid-friendly.” This thesis explores how this came to be, by exploring the following questions: (1) What were the differences in the development and perception of the animation industries in Japan and the United States? (2) Why/how did people in the United States take such interest in anime? (3) What is the role of anime conventions within the anime fandom community, both historically and in the present? These questions were answered with a mix of historical research, mapping, and interviews that were conducted in 2015 at Anime Expo, North America’s largest anime convention. This thesis concludes that anime would not have succeeded as it has in the United States without the heavy involvement of domestic animation fans. Fans created networks, clubs, and conventions that allowed for the exchange of information on anime, before Japanese companies started to officially release anime titles for distribution in the United States. -
Model Vulcanization Systems for Butyl Rubber and Halobutyl Rubber Manual
Exxon™ butyl and halobutyl rubber Model vulcanization systems for butyl rubber and halobutyl rubber manual Country name(s) 2 - Model vulcanization systems for butyl rubber and halobutyl rubber manual Model vulcanization systems for butyl rubber and halobutyl rubber manual - 3 Abstract The vulcanization of isobutylene-co-isoprene rubber (IIR), brominated isobutylene-co-isoprene rubber (BIIR), chlorinated isobutylene-co-isoprene rubber (CIIR), and brominated isobutylene-co-para-methylstyrene elastomer (BIMSM) differs from that of general-purpose rubbers (GPR). Butyl rubber has approximately 2% unsaturation in the backbone. Halobutyl rubber (BIIR and CIIR) incorporates the butyl backbone with either bromine or chlorine, which significantly increases the chemical reactivity of the isoprenyl units located in the butyl backbone. Similarly, in BIMSM the bromine atom is bonded to the para-methylstyrene (PMS) group, thus affording the completely saturated polymer backbone a site of chemical reactivity. Utilization of the unique attributes of butyl rubber and halobutyl rubbers with their minimal backbone unsaturation and of BIMSM elastomers with no backbone unsaturation is found in many areas of industry. These properties are excellent vapor impermeation, resistance to heat degradation, and improved chemical resistance as compared to general-purpose rubbers. However, this low amount of reactivity requires special consideration to vulcanize these isobutylene-based polymers. The type of vulcanization system selected is a function of the composite structure in which it is used, and the cured product performance requirements. Therefore, vulcanization systems vary and may include an accelerator package along with resins, zinc oxide, zinc oxide and sulfur, and quinoid systems. This review will discuss the types and selection of appropriate vulcanization systems for isobutylene-based elastomers. -

Isayev Dr. Robert Weiss _______________________ _______________________ Committee Member Dean of the College Dr. Thein Kyu Dr. Steven Cheng _______________________ ________________________ Committee Member Dean of the Graduate School Dr. Younjin Min Dr. George Newkome ________________________ Date ii ABSTRACT Compounding ground tire rubber (GTR) from whole waste tires with thermoplastic polyolefins, such as polypropylene (PP), is a possible way to manufacture thermoplastic elastomers and also to recycle waste tires to solve a major environmental problem. The present study looks at the effect of PP/GTR mixing ratio, rubber particle size, type of extruder, maleic anhydride grafted polypropylene (PP-g-MA) compatibilizer and ultrasound on the mechanical and rheological properties of PP and PP/GTR blends. PP and GTR were compounded at ratios of 30/70, 50/50 and 70/30. Whole tire GTR particles of 40 and 140 mesh sizes were used. Both the single screw extruder (SSE) and twin screw extruder (TSE) without and with ultrasonic treatment were applied. PP-g-MA compatibilizer was added to PP/GTR 50/50 blends at concentration of 10 wt %. Rheological, tensile and impact properties of uncompatibilized and compatibilized PP/GTR 50/50 blends were compared. -
