Patent number: 10883965Abstract: For method of utilizing a nondestructive evaluation method to inspect a steel material comprising at least one hysteretic ferromagnetic material and/or at least one nonhysteretic material to identify one or more material conditions and/or one or more inhomogeneities in steel material, the method can comprise the steps of: interrogating the hysteretic ferromagnetic material and/or the nonhysteretic material with an input time varying magnetic field; scanning the steel material and detecting a magnetic response and/or acoustic response over time from the hysteretic ferromagnetic material and/or the nonhysteretic material; determining a time dependent nonlinear characteristic of the received magnetic response and/or acoustic response; and correlating the time dependent nonlinear characteristic of the received magnetic response and/or acoustic response to the one or more material conditions and/or one or more inhomogeneities in steel material.Type: GrantFiled: October 19, 2018Date of Patent: January 5, 2021Assignee: ExxonMobil Research and Engineering CompanyInventors: Lang Feng, Qiuzi Li, Harry W.

Patent number: 10823701Abstract: A method for determining one or more material conditions of a hysteretic ferromagnetic material and/or a nonhysteretic material can include interrogating the hysteretic ferromagnetic material and/or the nonhysteretic material with an input time varying magnetic field and detecting a magnetic response and/or acoustic response over time from the hysteretic ferromagnetic material and/or the nonhysteretic material. The method can also include determining a time dependent nonlinear characteristic of the received magnetic response and/or acoustic response and correlating the time dependent nonlinear characteristic of the received magnetic response or acoustic response to one or more material conditions of the material.Type: GrantFiled: October 19, 2018Date of Patent: November 3, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Lang Feng, Qiuzi Li, Harry W.

Patent number: 10654019Abstract: A system for controlling the ion content of a colloidal system. A porous deionizer is used to selectively remove and isolate ions from a colloidal system. The colloidal particles within the system have their attraction/repulsion tuned by control of the ion content to alter the interaction between the colloidal particles.Type: GrantFiled: March 14, 2018Date of Patent: May 19, 2020Assignee: NEW YORK UNIVERSITYInventors: Paul M. Chaikin, Rodrigo Guerra

Publication number: 20190145933Abstract: Provided is a method of utilizing a nondestructive evaluation method to inspect/screen steel components (like plates), steel metal pipes, and seam welds and girth welds of the pipes to identify material phases and assess material qualities. The method includes: providing a DC magnetic field from a magnet to a steel plate, pipe, or weld composed of at least one hysteretic ferromagnetic material followed by scanning the plate, pipe, or weld and recording magnetic responses from two or more suitable sensors disposed at locations with different magnetic field strengths in the regions of interest configured to receive magnetic responses; and correlating all the said received magnetic responses to one or more material qualities and/or material phases of the plate, pipe, or weld. The one or more material qualities includes regions of higher hardness, regions of metal loss, regions of surface cracks, amount of undesirable phases, and combinations thereof.Type: ApplicationFiled: October 19, 2018Publication date: May 16, 2019Inventors: Lang Feng, Qiuzi Li, Harry W.

Patent number: 8687274Abstract: While gold wire grids have been used to polarize infrared wavelengths for over a hundred years, they are not appropriate for shorter wavelengths due to their large period. With embodiments of the present invention, grids with periods a few tens of nanometers can be fabricated. Among other things, such grids can be used to polarize visible and even ultraviolet light. As a result, such wire grid polarizers have a wide variety of applications and uses, such as, e.g., in the fabrication of semiconductors, nanolithography, and more.Type: GrantFiled: October 31, 2006Date of Patent: April 1, 2014Assignees: Kabushiki Kaisha Toshiba, Princeton UniversityInventors: Koji Asakawa, Vincent Pelletier, Mingshaw Wu, Douglas H. Adamson, Richard A. Register, Paul M. Chaikin, Young-Rae Hong
