Innovative Clean Coal Technology (ICCT): Demonstration of innovative applications of technology for cost reductions to the CT-121 FGD process

The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

Superplastic deformation properties of Ti-6Al-4V (open access)

Superplastic deformation properties of Ti-6Al-4V

Superplastic forming of Ti-6Al-4V was investigated with three heats of material to examine the effects of extrinsic and intrinsic variables on strain rate sensitivity and flow stress. Tension tests with strain rate jumps and step strain rate tests were used to determine the effects of strain rate, strain, and temperature on strain rate sensitivity of Ti-6Al-4V. Superplastic forming of Ti-6Al-4V is strongly influenced by deformation temperature. The uniform elongation and the strain rate sensitivity were maximized at 900{degree}C in the temperature range tested. In the strain rate range tested, strain rate sensitivity increased slightly as the strain rate decreased. In examining the results, it was apparent that at high strains, grain growth decreased strain rate sensitivity. This decrease was a strong function of temperature, which minimized at 875{degree}C. The strong dependence of superplastic behavior on temperature can be related to relative amounts of alpha and beta in the microstructure, as shown in the model for superplastic deformation of Ti-6Al-4V.

The OZI rule: A unique selector of glueballs and hadron spectroscopy (open access)

The OZI rule: A unique selector of glueballs and hadron spectroscopy

In the first part of this talk I have reviewed the history of the OZI rule. I then have shown how it is a unique selector glueballs and new quarks in hadron spectroscopy. In particular the only glueball candidates which cannot be explained by other hypotheses within QCD are the I{sup G}J{sup PC} = 0{sup +}2{sup ++} g{sub T}(2010), g{sub T},(2300) and g{sub T{double prime}}(2340) observed in the OZI suppressed reaction {pi}{sup {minus}} p {yields} {phi}{phi}n. The narrowness of the J/{psi} and T can only be explained by OZI suppression. I then reminisced about the 1954 Rochester Conference in which our work on {pi}{sup {plus minus}}p total cross sections and {pi}{sup {plus minus}} production combined gave convincing evidence for the delta being the first resonance. Described how the 1964 Dubna Conference results on small angle {pi}{sup {plus minus}}p elastic scattering led to the first critical experimental check of the pion-nucleon forward dispersion relations which showed that the basic axions of modern field theory worked on strong interactions at high energies. I finally reminisced about glueballs in the 1982 and 1988 Rochester Conferences. 52 refs., 17 figs., 3 tabs.
