Research ArticleOpen accessEvery word in the titleMolecular Interaction Studies of H-Bonded Complexes of Benzamide in 1,4-Dioxan with Alcohols From Acoustic and Thermodynamic ParametersAN. Kannappan, R. Kesavasamy, V. PonnuswamyThe ultrasonic velocity, density and viscosity measurements were carried out for the mixtures of benzamide with Propan-2-ol, butan-1-ol, 1-pentanol and n-hexanal in 1,4-dioxan at 303, 308 and 313K. The derived acoustic and thermodynamic parameters namely adiabatic compressibility, free length, free volume, internal pressure, viscous relaxation time and Gibbs free energy were evaluated with a view to investigate the nature of … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,277 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProduction of Biodiesel by Enzymatic Transesterification: ReviewA.E. Ghaly, D. Dave, M.S. Brooks, S. BudgeProblem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel production. In order … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 21,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunomodulatory and Antioxidant Effects of Stachys Japonica Miq. Ethanol Extract on Cyclophosphamide-Induced Immunosuppressed Mice and its Phytochemical CompositionXueping Jiang, Jianglong He, Yanjun Chen, Fang WangStachys japonica Miq. is an edible wild botanical drug and a traditional medicine in China. This study focused on examining the phytochemical profile and antioxidant properties of the ethanol extract of S. japonica Miq (SJEE) in vitro, as well as its immunomodulatory and antioxidant activities in cyclophosphamide (Cy)-induced immunosuppressed mice. The SJEE was analysed by UPLC-HRMS/MS. 36 Polyphenols, including flavonoids, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 13 Apr 2026 · 1,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractProfiling the Volatile Compound of Indonesian Rendang Using GC-MS/MS AnalysisDaimon Syukri, Abdi, Tuty Anggraini et al.Rendang is an indigenous food from west Sumatra with a distinct flavor and aroma. Different rendang production methods have an impact on its sensory qualities, including flavor and aroma. Finding the volatile substances that distinguish the aroma of each rendang was the aim of this investigation. In this experiment, five distinct Indonesian rendangs were used. Using the Head Space-Solid Phase … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 13 Nov 2023 · 6,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractEssential Oils from The Dropped Flowers of Camellia japonica: Extraction Optimization, Chemical Profile and Antibacterial PropertyYunqi Kong, Gaochao Wang, Xinyu Wang et al.Camellia japonica is one of the most economically valuable species that can be taxonomically placed in the Theaceae family. Many horticultural varieties of C. japonica have been cultivated as ornamental trees worldwide, owing to their charming flowers. However, young C. japonica flowers usually drop in a “decapitated” form during the peak flowering stage, causing a resource waste. In this study, … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 27 Jan 2021 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIELECTRIC CHARACTERIZATION OF LIQUID CONTAINING LOW ALCOHOLIC CONTENT FOR POTENTIAL HALAL AUTHENTICATION IN THE 0.5-50 GHz RANGEZurina Zainal Abidin, Fatin Nordalila Omar, Pavithiran Yogarajah et al.A potential method for detection and discrimination of alcoholic containing drinks for halal authentication using dielectric properties has been investigated. Behaviors of several pure alcohols, alcohol solution in water and also liquids with alcoholic contents were studied for verification purpose. Dielectric constant and dielectric loss factor for low concentration of ethanol solutions were measured over the microwave frequency from 0.5 … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 24 Apr 2014 · 7,671 accessesView PDFCite
