Publication number: 20240203747Abstract: The present invention provides an isotropic etching method of two-dimensional semiconductor materials. The present invention provides an isotropic etching method of two-dimensional semiconductor materials including a first operation of arranging an etching object having a two-dimensional transition metal chalcogenide layer inside an etching space of a remote plasma system in which a discharge space and the etching space are separated, a second operation of extracting oxygen or halogen radical among plasma generated in the discharge space and reacting the two-dimensional transition metal chalcogenide layer with a surface to form an oxide layer and a radical adsorbate layer, and a third operation of selectively removing the oxide layer and the radical adsorbate layer in the etching space, wherein only an upper layer of the two-dimensional transition metal chalcogenide is precisely etched in units of atoms without defects and damage in a lower layer.Type: ApplicationFiled: December 13, 2023Publication date: June 20, 2024Applicant: Research & Business Foundation SUNGKYUNKWAN UNIVERSITYInventors: Geun Young YEOM, Ji Eun KANG, Seong Jae YU, You Jin JI, Hye Won HAN, Ji Min KIM

Patent number: 7683070Abstract: It has now been found that certain novel N-(substituted aryl)-4-(disubstituted methyl)piperidine and pyridine derivatives have provided unexpected insecticidal activity. These compounds are represented by formula (I): wherein m, n, q, r, and s are independently selected from 0 or 1; and p is 0, 1, 2, or 3; A is C or CH; and B, D, E, R, R1, R2, R3, R4, R5, R6, R7 and R8 are fully described herein. In addition, compositions comprising an insecticidally effective amount of at least one compound of formula I, and optionally, an effective amount of at least one of a second compound, with at least one insecticidally compatible carrier are also disclosed; along with methods of controlling insects comprising applying said compositions to a locus where insects are present or are expected to be present.Type: GrantFiled: October 17, 2007Date of Patent: March 23, 2010Assignee: FMC CorporationInventors: Ping Ding, Robert N. Henrie, II, Daniel H. Cohen, John W. Lyga, David S. Rosen, George Theodoridis, Qun Zhang, Walter H. Yeager, Stephen F. Donovan, Stephen Shunxiang Zhang, Inna Shulman, Seong Jae Yu, Guozhi Wang, Y.

Patent number: 7164021Abstract: Novel compounds which selectively bind to the ?-opioid receptor have been designed. These compounds have greater selectivity, improved water (blood) solubility, and enhanced therapeutic value as analgesics. Because agonists with selectivity for the ?-opioid receptor have shown promise in providing enhanced analgesis without the addictive properties, the compounds of the present invention are better than morphine, naltrindole (NTI), spiroindanyloxymorphone (SIOM), and other known ?-opioid receptor selectors as analgesics.Type: GrantFiled: September 18, 2003Date of Patent: January 16, 2007Assignee: The Curators of The University of MissouriInventors: William J.
