Theoretical investigation of the oxygen bond dissociation energies in graphene oxide
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)The theoretical vibrational spectrum, oxygen bond dissociation energies (BDE), atomic charges and hydrogen bonding has been investigated using wB97XD/6-31g(d) method of calculation. The order of BDE for C-O comes in the ... -
Theoretical investigation on the effect of individual stage-gain selection on the 3-dB bandwidth of three-op-Amp difference amplifiers
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)The differential gain of a three-op-Amp difference amplifier is determined by the product of the gain values of its two stages. Usually, the total desired differential gain is assigned to the first stage while the gain of ... -
Theoretical Simulation of Thermal Deformations in Concrete Beams Reinforced with Two Overlapped FRP Bars in Cold Regions
( Qatar University Press , 2023 , Conference Paper)The thermal incompatibility in transverse direction between concrete and fiber reinforced polymer (FRP) bars may cause tensile circumferential cracks within concrete under low temperatures, and consequently, the failure ... -
Theoretical Studies of a Silica Functionalized Acrylamide for Calcium Scale Inhibition
( MDPI , 2022 , Article)The calcium carbonate (CaCO3 ) scale is one of the most common oilfield scales and oil and gas production bane. CaCO3 scale can lead to a sudden halt in production or, worst-case scenario, accidents; therefore, CaCO3 scale ... -
Theoretical studies of methane adsorption on Silica-Kaolinite interface for shale reservoir application
( Elsevier B.V. , 2021 , Article)Shale gas is mostly made up of methane and is currently being exploited in fulfilling the world's energy demands. Density Functional Theory (DFT) and Molecular Dynamics (MD) techniques are employed for understanding methane ... -
Theoretical study of laser light generation and color image formation: FA1:Cs+ and FA2:Li+ centers at the low coordination (100) and (110) surfaces of AgCl and AgBr
( Wiley Periodicals, Inc. , 2005 , Article)The FA1:Cs+ and FA2:Li+ color centers at the low coordination (100) and (110) surfaces of AgCl and AgBr play important roles in laser light generation and color image formation. Double-well potentials at these surfaces are ... -
