Publication number: 20240011906Abstract: An europium doped Ni(BTC) Metal Organic Framework (MOF), Eu@Ni(BTC), as a sensor for detecting heteroaromatic compounds. Eu@Ni(BTC) shows selectivity towards thiophene and pyrrole with a detection limit of 0.2 and 8.4 ppm for thiophene and pyrrole, respectively. The sensor can be easily regenerated and can be used to analyze thiophene in water.Type: ApplicationFiled: July 5, 2022Publication date: January 11, 2024Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Aasif HELAL, Mohammad Mizanur RAHMAN, Muhammed NAEEM, Md. Eyasin ARAFAT, Muhammad USMAN

Patent number: 11518891Abstract: A method is described for inhibiting marine fouling on a surface. The surface is contacted with a composition comprising a waterborne polyurethane that is crosslinked with an acrylic acid functionalized polysaccharide, water, and a preservative. The composition is then dried to form a deposited film. The polysaccharide may be xanthan.Type: GrantFiled: March 4, 2020Date of Patent: December 6, 2022Assignee: King Fahd University of Petroleum and MineralsInventors: Mohammad Mizanur Rahman, Md. Hasan Zahir, Mohammad Abu Jafar Mazumder

Patent number: 11434339Abstract: A heat energy storage system may have a shape-stabilized composite prepared using an easy impregnation method involving a porous Ca2+-doped MgCO3 matrix and PEG as the functional phase. The heat storage capability, microstructures, and interactions with the PEG/CaMgCO3 composite can be characterized by DSC, SEM imaging, FT-IR spectroscopy, and TGA. Likely because of the synergistic phase change effect of CaMgCO3 and PEG, the PEG/CaMgCO3 composites can have high thermal enthalpies, and their enthalpy efficiencies are substantially higher than those of traditional shape stabilized PCMs. The functional material PEG can permeate porous CaMgCO3 matrices under capillary action. Liquid PEG can be stabilized within the porous matrix, and/or the CaMgCO3 matrix can improve the thermal stability of the PEG. The high heat energy storage properties and good thermal stability of such organic-inorganic composites offers utility in a range of applications, including thermal energy storage.Type: GrantFiled: February 19, 2020Date of Patent: September 6, 2022Assignee: King Fahd University of Petroleum and MineralsInventors: Md. Hasan Zahir, Mohammad Mizanur Rahman

Patent number: 11407904Abstract: Methods of preparing waterborne polyurethane dispersions involving reacted units of a polyol, an acidic diol, a hydroxy functionalized polyhedral oligomeric silsesquioxane, a diisocyanate, and a chain extender. Polyurethane coatings based on these waterborne polyurethane dispersions are evaluated on their hydrophobicity (water contact angle), mechanical strength (e.g. tensile strength, Young's modulus, elongation at break), and antifouling properties.Type: GrantFiled: February 11, 2019Date of Patent: August 9, 2022Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mohammad Mizanur Rahman, Md.

Patent number: 11306238Abstract: A heat storage material comprising mesoporous Mg(OH)2 and having pores loaded with a phase change material is described. The heat storage material has a cooling latent heat of 130-140 J/g, and a solidification enthalpy of 120-135 J/g, and a thermal conductivity of 25-45 W·m?1·K?1. The phase change material may be polyethylene glycol, and the polyethylene glycol does not leak from the pores of the mesoporous Mg(OH)2 when heating or cooling over phase transitions.Type: GrantFiled: October 3, 2019Date of Patent: April 19, 2022Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Md.

Patent number: 11118018Abstract: A method of preparing stable waterborne polyurethane nanocomposite with a long shelf-life time is described. The stability of the nanocomposite is achieved by effective mechanical and sonication mixing of diisocynate and clay. Also, the stability is achieved through optimization of the amount of clay and carboxylic acid with hydroxyl functionality.Type: GrantFiled: May 31, 2018Date of Patent: September 14, 2021Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mohammad Mizanur Rahman, Ahmad Sorour
