Patent number: 10894888Abstract: The invention provides a dust repellant and anti-reflective inorganic coating and the method for preparing the coating. The dust repellant and anti-reflective inorganic coating includes nano-porous silica (SiO2) network of about 5 nm to about 35 nm and is characterized by cracks. The method of preparing the dust repellant and anti-reflective inorganic coating on a substrate includes mixing of aqueous SiO2 solution with a solvent. The aqueous SiO2 solution with the solvent is stirred to form a solution. The solution is coated on the substrate to form a film on the surface of the substrate. Thereafter, the film is annealed by heating the film to a temperature of about 500° C. to about 700° C. within a period of about 2 minutes to about 2 hours. Finally, the film is allowed to cool down.Type: GrantFiled: December 1, 2015Date of Patent: January 19, 2021Assignees: KING ABDULAZIZ CITY FOR SCIENCE AND TECHNOLOGY, FRAUNHOFER INSTITUTE FOR SILICATE RESEARCH ISCInventors: Mohammed Abdullah Bahattab, Walther Glaubitt, Mark Mirza, Mohammed I Alhussani

Patent number: 9073057Abstract: The invention provides a method for separating submicron fraction of carbon nano-materials. The method includes grinding of the carbon nano-materials. Upon grinding, the carbon nano-materials are mixed in water to prepare a mixture. The mixture is then treated in an ultrasonic bath to prepare a suspension. The suspension is allowed to undergo a liquid sedimentation. After the liquid sedimentation, a supernatant is collected and filtered to obtain a solid residue of the submicron fraction of the carbon nano-materials.Type: GrantFiled: December 4, 2013Date of Patent: July 7, 2015Assignee: King Abdulaziz City for Science and TechnologyInventors: Mohammed A Abdullah Bahattab, Siarhei Zhdanok, Andrei Krauklis, Kirill Borisevich, Pavel Stanavy
