Synthesis, crystal structure analysis, spectral IR, UV–Vis, NMR assessments, electronic and nonlinear optical properties of potent quinoline based derivatives: Interplay of experimental and DFT Study
Publication date: Available online 10 October 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Muhammad Khalid, Muhammad Adeel, Malik Aman Ullah, Muhammad Usman Khan, Muhammad Nawaz Tahir, Ataualpa Albert Carmo BragaAbstractQuinoline and its derivatives are widely studied by both synthetic and computational chemists due to their exciting perspectives in biological and nonlinear optical (NLO) research. Herein, three novel arylated quinolines: 3-(4-acetylphenyl)quinoline (1), 3-(4-(methylthio)phenyl)-quinoline (2) and 3-(4-phenoxyphenyl)quinoline (3) were synthesized employing Pd catalyzed Suzuki-Miyaura cross-couplin...

A novel approach to produce monodisperse hollow pure silica spheres
Publication date: Available online 22 September 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Sultan Akhtar, Şeyda Tuğba Günday, B. Rabindran Jermy, M.A. Almessiere, Ayhan BozkurtAbstractIn this work, we report an efficient method to produce pure hollow silica spheres (HSS) using phenyltrimethoxysilane (PTMS) compound. The production of HSS was carried out via hydrolysis of PTMS in the aqueous media and followed by a condensation reaction to form silica spheres with phenyl groups. The product was then calcined to remove phenyl groups and obtain pure silica spheres with>95% fine structure. The chemical nature o...

Fabricating hierarchical ZSM-5 to induct long chain antioxidant coenzyme Q10 for biomedical application
Publication date: Available online 25 September 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Vijaya Ravinayagam, B. Rabindran JermyAbstractThe study investigates the hydrophobic antioxidant Coenzyme Q10 (CoQ10) adsorption over industrially relevant hierarchical ZSM-5 for potential therapeutic applications. The designing of hierarchical nanocomposites was optimized with two different NaOH/CTAB ratios (0.18 and 0.62) over ZSM-5 (SiO2/Al2O3 = 22–27) of different crystal sizes (0.5 µm, 2.0 µm and 3.0 µm) and different SiO2/Al2O3 ratios (23, 80, 280 and 1500) through top-down approach. Hydrothermal sta...

Synthesis and characterization of mesoporous zinc layered hydroxide-isoprocarb nanocomposite
Publication date: Available online 26 September 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Zuhailimuna Muda, Norhayati Hashim, Illyas Md Isa, Suriani Abu Bakar, Noorshida Mohd Ali, Mohd Zobir Hussein, Mazidah Mamat, Siti Munirah SidikAbstractThe ion exchange method was used to intercalate a poor water-soluble insecticide, isoprocarb into zinc layered hydroxide (ZLH). PXRD analysis indicated the successful intercalation with good crystallinity for the resulting nanocomposite, with a basal spacing of 33.1 Å. FTIR analyses showing the resemblance of an absorption peak of the nanocomposite with the host and the g...

Evidence for enhancement of corrosion resistance of carbon steel after exposure to high-dose gamma radiation
Publication date: Available online 27 September 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Talal A. Aljohani, Mohammed H. Geesi, A. KaibaAbstractThis paper reports the effect of gamma radiation on carbon-steel corrosion in a synthetic sodium-chloride electrolyte [0.6M] which is a suitable candidate for thick-wall radioactive waste containers. The corrosion properties were studied by linear polarization (LP), Tafel plots, and electrochemical impedance spectroscopy (EIS). Carbon steel exposed to a high irradiation dose was found to have enhanced corrosion resistance, which is consistent with the formation of Fe2...
