Palke, Dale Robert (Texas A&M University. Libraries, 1989)A pulse-flow reaction system has been used to investigate the conversions of C₂-C₇ alkanes over SiO₂-,La₂O₃-, and charcoal-supported nickel catalysts. The effects of nickel loading level, reaction temperature, and structure ...
-
Jensen, Jeffrey Le (Texas A&M University. Libraries, 1983)The active sites on La(,2)O(,3) that are responsible for 1-butene isomerization are "acid-base" pair sites which are generated by the thermal removal of surface hydroxyls over the pretreatment temperatue range 400(DEGREES)C ...
-
Wan, Ben-Zu (Texas A&M University. Libraries, 1986)The shape selectivity and catalytic properties of organically pillared zirconium phosphates, novel aluminophosphate (AlP12A), AlPO[4]-5 with transition metal oxides, and silicalite with transition metal oxides have been ...
-
Zhao, Dan (2012-02-14)Developing the synthetic control required for the intentional 3-D arrangement of atoms remains a holy grail in crystal engineering and materials chemistry. The explosive development of metal-organic materials in recent ...
-
Calvert, Craig Steven (Texas A&M University. Libraries, 1981)Seven soil kaolinites and four geologic kaolinites were studied to determine the extent, valence, and coordination number of iron in the kaolinite structure. Three synthetic kaolinites of varying iron content, as well as ...
-
Sun, Yujia (2018-08-15)Metal-organic frameworks (MOFs) are a class of newly emerged crystalline porous materials consisting of metal ions or clusters and organic linkers. Through judicious choice of inorganic joints and organic struts, the ...
-
Rudolf, Phillip Reinhol (Texas A&M University. Libraries, 1983)Single crystal X-ray diffraction has for many become the definitive analysis technique. The procedure to collect data and to solve structures is not only readily available but is also highly automated. This is not the case ...
