In the eye of the muses : selections from the Clark Atlanta University art collection by Clark Atlanta University ( Book )
2 editions published in 2012 in English and held by 69 WorldCat member libraries worldwide
Clark Atlanta University Art Galleries in Atlanta, Georgia celebrates the seventieth anniversary of the founding of its permanent collection and the sixtieth anniversary of the unveiling of the 'Art of the Negro' murals with this commemorative volume. Initially conceived with works selected from annual exhibitions, the collection today constitutes a rare and remarkable assemblage of African-American art. This book tells the story of the Atlanta University Art Annuals held between 1942 and 1970, from which the collection stemmed, cataloging the 887 artists who participated and crucially enhancing our understanding of art by African Americans. In an accompanying essay, Hale Woodruff's 'Art of the Negro' mural suite is eloquently explicated by art critic Jerry Cullum. 'In the Eye of the Muses' presents a monumental catalogue of a unique collection

IMPROVED CATALYSTS FOR HEAVY OIL UPGRADING BASED ON ZEOLITE Y NANOPARTICLES ENCAPSULATED IN STABLE NANOPOROUS HOST ( )
7 editions published between 2005 and 2007 in English and held by 9 WorldCat member libraries worldwide
The objectives of this project are to synthesis nanocrystals of highly acidic zeolite Y, encapsulate them within the channels of mesoporous (nanoporous) silicates or nanoporous organosilicates and evaluate the ''zeolite Y/Nanoporous host'' composites as catalysts for the upgrading of heavy petroleum feedstocks. Our results to date are summarized as follows. The synthesis of high surface ordered nanoporous silica of expanded pore diameter of 25 nm (larger than the standard size of 8.4 nm) using trimethylbenzene as a pore size expander was accomplished. The synthesis of zeolite Y nanoparticles with median pore size of approximately 50 nm (smaller than the 80 nm typically obtained with TMAOH) using combined TMABr/TMAOH as organic additives was also accomplished. The successful synthesis of zeoliteY/Nanoporous host composite materials by sequential combination of zeolite precursors and nanoporous material precursor mixtures was implied based on results from various characterization techniques such as X-Ray diffraction, infrared spectra, thermal analysis, porosimetry data. The resulting materials showed pore sizes up to 11 nm, and infrared band at 570 cm⁻¹ suggesting the presence of both phases. Work in the immediate future will be focused on the following three areas: (1) Further characterization of all-silica and aluminosilicate mesoporous materials with expanded pore sizes up to 30 nm will continue; (2) Research efforts to reduce the average particle size of zeolite nanoparticles down to 35-30 nm will continue; (3) Further synthesis of polymer-SBA15 nanocomposites will be conducted by changing the amount and chemistry of the zeolitic precursors added; and (4) Investigation on the catalytic properties of the materials using probe catalytic reactions (such as cumene cracking), followed by catalytic testing for heavy oil conversion

A flow reactor is being constructed at Georgia Tech for the NO decomposition reaction. The reactor is partially complete with the construction of a flow meter/controller system and a temperature controller system in place now. The stainless steel reactor tube and the furnace have been fabricated and fit to the sub-assembly containing the temperature control devices. The reactor sampling system is under fabrication. The authors plan to purchase a GC-MS to determine the composition of the exit gas. They have used Raman spectroscopy to characterize Zeolite A, a cobalt ethylenediamine complex, Co(en)₃Cl₃, and Zeolite A impregnated with the cobalt complex. The Raman spectra from 1,700--100 cm⁻¹ are shown
A novel approach to highly dispersing catalytic materials in coal for gasification ( )
6 editions published between 1989 and 1992 in English and held by 6 WorldCat member libraries worldwide
This project seeks to develop a technique, based on coal surface properties, for highly dispersing catalysts in coal for gasification and to investigate the potential of using potassium carbonate and calcium acetate mixtures as catalysts for coal gasification. The lower cost and high catalytic activity of the latter compound will produce economic benefits by reducing the amount of K₂CO₃ required for high coal char reactivities. The work is focused on the elucidation of coal-catalyst precursor interactions in solution and the variables which control the adsorption and dispersion of coal gasification metal catalysts. In order to optimize coal-metal ion interactions and hence maximize catalyst activity, the study examines the surface electrochemistry of a lignite, a subbituminous, and a bituminous coals and their demineralized and oxidized derivatives prior to loading with the catalytic materials. The surface electrical properties of the coals are investigated with the aid of electrophoresis, while the effects of the surface charge on the adsorption of K and Ca{sup 2+} are studied by agitating the coals with aqueous solutions of potassium and calcium. A zeta meter, a tube furnace, and other equipment required for the investigation have been acquired and installed. Preliminary work shows that the lignite (Psoc 1482) is negatively charged between pH 1.8 and pH 11.0 and has an isoelectric point of pH 1.8

IMPROVED CATALYSTS FOR HEAVY OIL UPGRADING BASED ON ZEOLITE Y NANOPARTICLES ENCAPSULATED IN STABLE NANOPOROUS HOSTS ( )

The focus of this project is to improve the catalytic performance of zeolite Y for petroleum hydrocracking by synthesizing nanoparticles of the zeolite ({approx}20-25 nm) inside nanoporous silicate or aluminosilicate hosts. The encapsulated zeolite nanoparticles are expected to possess reduced diffusional path lengths, hence hydrocarbon substrates will diffuse in, are converted and the products quickly diffused out. This is expected to prevent over-reaction and the blocking of the zeolite pores and active sites will be minimized. In this phase of the project, procedures for the synthesis of ordered nanoporous silica, such as SBA-15, using block copolymers and nonionic surfactant were successful reproduced. Expansion of the pores sizes of the nanoporous silica using trimethylbenzene is suggested based on shift in the major X-Ray Diffraction peak in the products to lower 2 angles compared with the parent SBA-15 material. The synthesis of ordered nanoporous materials with aluminum incorporated in the predominantly silicate framework was attempted but is not yet successful, and the procedures needs will be repeated and modified as necessary. Nanoparticles of zeolite Y of particle sizes in the range 40 nm to 120 nm were synthesized in the presence of TMAOH as the particle size controlling additive

The HBCU/MI ET Consortium was established in January 1990, through a Memorandum of Understanding (MOU) among its member institutions. This group of research oriented Historically Black Colleges and Universities and Minority Institutions (HBCU/MIs) agreed to work together to initiate or revise education programs, develop research partnerships with public and private sector organizations, and promote technology development to address the nation's critical environmental contamination problems. The Consortium's Research, Education and Technology Transfer (RETT) Plan became the working agenda. The Consortium is a resource for collaboration among the member institutions and with federal an state agencies, national and federal laboratories, industries, (including small businesses), majority universities, and two and four-year technical colleges. As a group of 17 institutions geographically located in the southern US, the Consortium is well positioned to reach a diverse group of women and minority populations of African Americans, Hispanics and American Indians. This Report provides a status update on activities and achievements in environmental curriculum development, outreach at the K--12 level, undergraduate and graduate education, research and development, and technology transfer

The role of catalyst precursor anions in coal gasification ( )
3 editions published in 1992 in English and held by 3 WorldCat member libraries worldwide
The aims of the proposed project are to enrich our understanding of the roles of various aqueous soluble catalyst precursor anions on the surface electrical properties of coal and to ascertain the influence of the surface charge on the adsorption, dispersion, and activities of calcium and potassium. These goals will be achieved by impregnating a demineralized North Dakota lignite (PSOC 1482) with calcium or potassium catalyst precursors containing acetate (CH[sub 3]COO[sup [minus]]), chloride (CI[sup [minus]]), nitrate (NO[sub 3][sup [minus]]), sulfate (SO[sub 4][sup 2[minus]]), and carbonate (CO[sub 3][sup 2[minus]]) anions. In the past quarter, the effects of (CH[sub 3]COO[sup [minus]]), CI[sup [minus]], (NO[sub 3][sup [minus]]), (CO[sub 3][sup 2[minus]]) or (CO[sub 3][sup 2[minus]]) on the surface charge properties of the coal has been initiated using the calcium salts of these anions. Like the corresponding potassium compounds investigated previously, increasing anion concentrations produce less negative charge on the coal surface through the interaction of calcium ions with the surface. This was confirmed by metal adsorption and chemical analysis of the filtered coal particles. The extent of metal adsorption was strongly dependent on the catalyst precursor. For potassium, maximum metal uptake from solution was obtained using potassium carbonate, followed by potassium acetate, while the lowest metal loadings were obtained when using the chloride, nitrate or the sulfate of potassium. The adsorption data are generally in agreement with the zeta potential results and suggest electrostatic attraction between the metal cation and the anionic coal surface. Fourier transform infrared studies are in progress to elucidate the coal-catalyst interactions
Alternative formulations of regenerable flue gas cleanup catalysts ( )
3 editions published between 1991 and 1992 in English and held by 3 WorldCat member libraries worldwide
We have used non-aqueous impregnation techniques to prepare an aluminum oxide surface covered with a well-dispersed magnesium oxide layer using magnesium acetylacetonate dehydrate [Mg(acac)[sub 2][sm bullet]2H[sub 2]0] as a precursor. Using lithium acetylacetonate as a precursor, we have begun attempts to prepare a similarly well dispersed surface layer of lithium oxide.'' We have generated higher weight loadings of magnesium on alumina by using a Soxhlet extractor to dissolve the sparingly soluble Mg(acac)[sub 2][sm bullet]2H[sub 2]0 in methanol. With this device we are able to obtain loadings of MgO on the alumina up to 0.66 wt/wt%. The precursor samples were examined by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and our results indicate that the complex loses the water of hydration upon adsorption. It appears, however, that the initial form of the complex on the surface is as anhydrous crystallites. Heating the supported precursor under vacuum leads to melting'' of the crystals, which can be observed by DRIFTS. Decomposition of the precursor under nitrogen or air leads to very similar activity when adsorbing SO[sub 2]. SO[sub 2] uptake appears to be independent of whether O[sub 2] is Present in the gas stream or not. We have shown that SO[sub 2] adsorption increases with Mg-loading on the impregnated aluminas, with 0.85 additional molecules Of SO[sub 2] adsorbed for each additional Mg atom (or MgO molecule) on the surface. We have shown that non-aqueous impregnation leads to samples which are more efficient with regard to SO[sub 2] uptake per magnesium atom than aqueous impregnation
