    In this research, SO3H-functionalized Silica grafted 3-amino triazol has been prepared and identified through FT-IR, XRD, EDX, Fe-SEM, and TGA spectra. 3-chloropropyltriethoxysilane was first reacted with silica nanoparticles and then treated with 3-amino-1H-1,2,4-triazoles and grafted finally with chlorosulfonic acid to prepare SiO2@(CH2)3-AT/SO3H (SNPS-AT/SO3H). Aft ...

    Author(s): Chang-An Yu*, Xiao-long Li, Lian-Quan Gu and Linda Yu
    To understand the reaction mechanism of quinone-mediated electron transfer, a series of ubiquinone (Q)-derivatives with a bromine or chlorine atom at the 6-position and a different alkyl side chains at the 5-position of the benzoquinone ring were synthesized and characterized. The chemical properties and electron transfer activities were compared with the native ubiqu ...

    Scope of a short & obese patient for thymoma surgery with the risk of difficulty in weaning from general anaesthesia

    DOI Logo 10.17352/ojc.000035

    Published On: March 26, 2024 | Pages: 020 - 023

    Author(s): Krishna Prasad T*, Ajit Kumar Kayal, Kavin Adhithya and Balu Sankar
    Obese patients had more difficulty with tracheal intubation and a higher incidence of post-extubation stridor. Obesity is such a ubiquitous issue in our culture, and it is a significant risk factor for many diseases, thus it is not surprising that many obese patients are treated in ICU. The objective of this article is to explore challenges for short, obese patients ( ...

    A comprehensive study of the intrinsic defects in sublimation-grown SiC crystals, depending on the growth conditions and thermal annealing is carried out. Complexes of the intrinsic defects including carbon vacancy (VC) and impurities atoms are found in the Si-rich SiC crystals grown by physical vapor transport at low temperatures below 2200 °C. Similar defects are al ...

    The transformative role of Computational Fluid Dynamics (CFD) in chemical engineering

    DOI Logo 10.17352/ojc.000033

    Published On: March 12, 2024 | Pages: 001 - 003

    Author(s): Bibhab Kumar Lodh*
    Chemical engineering is a discipline intrinsically linked to fluid behavior. From reaction kinetics to reactor design, understanding how fluids flow, mix, and transfer heat is paramount. Traditionally, this relied heavily on experimentation, a time-consuming and resource-intensive process. The emergence of Computational Fluid Dynamics (CFD) has revolutionized the fiel ...
