Patent number: 11492257Abstract: A method of forming an alkali metal-doped calcium-SiAlON material is provided. The method includes mixing calcium-SiAlON powder and an alkali metal hydroxide to form a reaction mixture. The mixture further includes spark plasma sintering (SPS) the reaction mixture at 800 to 940 degrees Celsius (° C.) to form the alkali metal-doped calcium-SiAlON material. The alkali metal hydroxide is present in an amount of 0.1 to 10 weight percentage (wt. %), based on a total weight of the reaction mixture.Type: GrantFiled: May 11, 2022Date of Patent: November 8, 2022Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Abbas Saeed Hakeem, Qasem Ahmed Qasem Drmosh, Natalia Anna Wójcik, Sharafat Ali, Amar Kamal Mohamedkhair

Patent number: 9034169Abstract: The method for detection of cyanide in water is a method for the detection of a highly toxic pollutant, cyanide, in water using ZnO2 nanoparticles synthesized locally by an elegant Pulsed Laser Ablation technique. ZnO2 nanoparticles having a median size of 4 nm are synthesized from pure zinc metal target under UV laser irradiation in a 1-10% H2O2 environment in deionized water. The synthesized ZnO2 nanoparticles are suspended in dimethyl formamide in the presence of Nafion, and then ultrasonicated to create a homogenous suspension, which is used to prepare a thin film of ZnO2 nanoparticles on a metal electrode. The electrode is used for cyanide detection.Type: GrantFiled: March 14, 2013Date of Patent: May 19, 2015Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mohammed Ashraf Gondal, Qasem Ahmed Qasem Drmosh, Z.
