Patent number: 8781055Abstract: A system and a process for producing selected isotopic daughter products from parent materials characterized by the steps of loading the parent material upon a sorbent having a functional group configured to selectively bind the parent material under designated conditions, generating the selected isotopic daughter products, and eluting said selected isotopic daughter products from the sorbent. In one embodiment, the process also includes the step of passing an eluent formed by the elution step through a second sorbent material that is configured to remove a preselected material from said eluent. In some applications a passage of the material through a third sorbent material after passage through the second sorbent material is also performed.Type: GrantFiled: November 3, 2010Date of Patent: July 15, 2014Assignee: Battelle Memorial InstituteInventors: James J.

Patent number: 8012403Abstract: Porous ceramic and hybrid ceramic films are useful as low dielectric constant interlayers in semiconductor interconnects. (Hybrid ceramic films are defined as films that contain organic and ceramic molecular components in the structure, as, for example, organosilicates). This invention describes the usefulness of humidity treatments (using specific temperature/humidity treatments as illustrative examples) in increasing mechanical integrity of porous dielectric films with minimal detrimental effect on film porosity or dielectric constant and with no adverse impact on film quality. The efficacy of such treatments is illustrated using surfactant-templated mesoporous silicate films as an example. This invention also describes a specific family of additives to be used with highly pure alkali-metal-free ceramic and hybrid precursors for such dielectric films that will enable better control of the film porosity and quality and lower dielectric constants with the required mechanical integrity.Type: GrantFiled: September 14, 2001Date of Patent: September 6, 2011Assignee: Battelle Memorial InstituteInventors: Jerome C.
