标题 :Triazole- And/Or Triazolium-Based Polymers And Copolymers As Additives For Chemical Mechanical Planarization Slurries
发明人：LARBIG GREGOR; KIRSCH PEER; HENGST MATTHIAS; SHI XIAOBO; STENDER MATTHIAS
权利人:VERSUM MAT US LLC
摘要:Synthesis of triazole- and/or triazolium-based polymers is disclosed. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising triazole- and/or triazolium-based polymers; and water. The use of the synthesized triazole- and/or triazolium-based polymers in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

参考标题:Initial Intraorgan Formation Of Mercapturic Acid.作者:Kazumi Sano,Yoji Ikegami,Takashi Uesugi
摘要:The Disposition Of S-Benzyl-Glutathione (Bsg) In Male Wistar Rats Was Evaluated By The Hplc Method To Examine Whether The Kidney And Liver Contributed Independently To The Biosynthesis Of S-Benzyl-N-Acetylcysteine (Bnac), A Mercapturic Acid (Chart 1). After Intravenous Injection, Bsg Was Rapidly Transported In Both The Kidney And The Liver At A Ratio Of About 7:3. Simultaneously, A Large Amount Of Bnac Was Found In Both The Kidney And The Liver. In The Kidney, S-Benzyl-Cysteine (Bcys) Reached A Maximum Concentration (Cmax) At 2 Min After Bsg Injection, Whereas Bnac Reached Cmax Within 3 To 5 Min. The Generation Of Bnac Was Also Observed In The Liver. While Renal Bnac Reached Cmax Within 3 To 5 Min, Hepatic Bnac Reached Cmax Around 5 Min After Bsg Injection. Moreover, The Elimination Half-Life Of The Bnac After Intravenous Injection Of The Bsg Was Equivalent To That Observed After Intravenous Injection Of The Bnac Itself. These Results Demonstrate That The Kidney Contributes To The Initial Intraorgan Generation Of Bnac And That This Mercapturic Acid Is Also Synthesized In The Liver And Preferentially Excreted Into Urine.
