标题:Structural And Magnetic Properties Of Co-C Composite Films And Co/c Multilayer Films
摘要:Co-C Composite Films And Co/c Multilayer Films Have Been Prepared By A Method Incorporating Ion Beam Sputtering And Plasma Chemical Vapor Deposition. It Has Been Found That The Structure And Magnetic Properties Of Both The Co-C Composite And The Co/c Multilayer Films Depend Strongly On The Substrate Temperature During Deposition. The Co-C Composite Film Deposited At Roorn Temperature Is Amorphous,With Relatively Low Saturation Magnetization And Coercivity. On The Other Hand,The Film Deposited At 250 Degreesc Is Composed Of Fine Co Crystallites Separated By Amorphous C Or Co-C Phase. As A Result,Both The Saturation Magnetization And Coercivity Are Increased Compared With The Film Deposited At Room Temperature. When Deposited At Room Temperature,The Co/c Multilayer Film Exhibits Good Periodicity,With A Period Of 70 Mn (Co: 40 Nm,C: 30 Nm) And Sharp And Flat Co-C Interfaces. High Magnetization (602 Emu/cm(3)) And Low Coercivity (1.6 Oe) Are Obtained For Such A Film. However,Increasing The Substrate Temperature To 250 Degreesc Was Found To Be Detrimental To The Magnetic Properties Due To The Formation Of Cobalt Carbide At The Co-C Interface.

摘要:The invention provides purified proteins, DNA sequences that code on expression therefore and recombinant DNA molecules, including hosts transformed therewith for transforming coffee plants to suppress the expression of enzymes necessary for ethylene synthesis. The DNA sequences and recombinant DNA molecules are characerized in that they code on expression for the enzymes ACC synthase or ACC oxidase that are elements of the pathway for ethylene biosynthesis in coffee plants. Coffee plants are transformed with vectors containing ACC synthase and/or with ACC oxidase DNA sequences that code on expression for the respective mRNA that is antisense to the mRNA for ACC synthase and/or ACC oxidase. The resulting antisense mRNA binds to the respective ACC synthase and/or ACC oxidase mRNA, thereby inactivating the mRNA encoding one or more enzymes in the pathway for ethylene synthesis. The described DNA sequences can also be used to block synthesis of ACC synthase or ACC oxidase using co-suppression. The result in either event is that the transformed plants are incapable of synthesizing ethylne, though other aspects of their metabolism is not affected.

标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks

摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.
