    摘要: It has been discovered that catalysts may be modified by depositing an agent derivative from an agent such as an organometallic compound upon them. Such a modification gives a catalyst useful in increased selectivity to para-substituted alkyl benzenes, such as para-xylene (PX), through reacting an aromatic compound such as toluene and/or benzene with a methylating agent from hydrogen and carbon monoxide and/or carbon dioxide and/or methanol. Using these selectivated catalysts, para-substituted alkyl benzenes can be recovered in a selectivity of 80% or greater, significantly better than the equilibrium concentration of 24%.

    摘要: Embodiments disclosed herein include methods in which a pair of openings are formed into semiconductor material, with the openings being spaced from one another by a segment of the semiconductor material. Liners are formed along sidewalls of the openings, and then semiconductor material is isotropically etched from bottoms of the openings to merge the openings and thereby completely undercut the segment of semiconductor material. Embodiments disclosed herein may be utilized in forming SOI constructions, and in forming field effect transistors having transistor gates entirely surrounding channel regions. Embodiments disclosed herein also include semiconductor constructions having transistor gates surrounding channel regions, as well as constructions in which insulative material entirely separates an upper semiconductor material from a lower semiconductor material.
