Patent number: 11180578Abstract: Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition, which use an N—O polymerization inhibitor, a quinone methide polymerization retarder, and an amine stabilizer having a primary and/or secondary amine group. In a mixture, the amine-based stabilizer can prevent antagonistic effects and can provide greater antipolymerant activity. In turn, the mixture inhibits apparatus fouling and improves the purity of monomer streams.Type: GrantFiled: July 12, 2019Date of Patent: November 23, 2021Assignee: Ecolab USA Inc.Inventors: Jonathan Masere, Andrew R.

Patent number: 8562935Abstract: The present invention is directed towards methods (processes) of providing large quantities of carbon nanotubes (CNTs) of defined diameter and chirality (i.e., precise populations). In such processes, CNT seeds of a pre-selected diameter and chirality are grown to many (e.g., hundreds) times their original length. This is optionally followed by cycling some of the newly grown material back as seed material for regrowth. Thus, the present invention provides for the large-scale production of precise populations of CNTs, the precise composition of such populations capable of being optimized for a particular application (e.g., hydrogen storage). The present invention is also directed to complexes of CNTs and transition metal catalyst precurors, such complexes typically being formed en route to forming CNT seeds.Type: GrantFiled: October 14, 2004Date of Patent: October 22, 2013Assignee: William Marsh Rice UniversityInventors: Robert H.

Patent number: 6890598Abstract: Aliphatic dithiocarboxylic acid compositions (ADTCAs) that form self-assembled monolayers (SAMs) on metal surface such as gold surfaces are disclosed. These new SAMs were characterized by optical ellipsometry, contact angle goniometry, and polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS). The data indicates that the ADTCAs generate well packed and highly oriented monolayer films on gold surfaces. A method for using the ADTCAs in micro-contact printing is also disclosed, where ADTCA SAM protected regions are capable of more efficient cleaning under mild conditions due to instabilities in the ADTCA compositions.Type: GrantFiled: March 6, 2002Date of Patent: May 10, 2005Inventors: Randall T. Lee, Ramon Colorado, Jr.
