The inner core layer comprised Pectin-Chitosan (PC) microcapsules, synthesized by complex coacervation, encapsulating Orange Peel Essential Oil (OPEOM) with an embedding efficiency of 83.08%. The outer shell layer consisted of Ethyl Cellulose (EC) doped with zinc-doped carbon dots (Zn-CDs, average size: … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 8 May 2026 · 1,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractNear Infrared Spectroscopy Identification Method for Five Chemical Types of Cinnamomum camphoraBailian Tu, Yueting Zhang, Yongjie Zheng et al.To more quickly and accurately identify the five chemical types of Cinnamomum camphora, a desktop and portable near-infrared spectrometer was used to collect the near-infrared spectra of the leaves of the five chemical types of C. camphora. Combined with chemometric methods, the near-infrared spectra of different chemical types of C. camphora were discriminated and analyzed. Using a desktop near-infrared spectrometer … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 20 Feb 2025 · 5,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploration and Characterization of Thermophilic Bacteria from the Kerinci-Jambi Geothermal Source for Alcohol ProductionAnthoni Agustien, Weni Cahyati, Yetria RildaAlcohol produced by thermophilic bacteria is renewable and a safe fuel because it is mainly based on microbial fermentation. This research needs to be done to find out the potential alcohol production of thermophilic bacteria because have many advantages such as degrading a much wider range of carbohydrates, the possibility of direct alcohol recovery from the fermentation broth, tolerance to … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 10 Feb 2024 · 5,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractExplosion of the Science Modification of Newtonian Dynamics Via Mach’s Inertia Principle and Generalization in Gravitational Quantum Bound Systems and Finite Range of the Gravity-Carriers, Consistent Merely On the Bosons and the FermionsMohsen LutephyNewtonian gravity is modified here via Mach's inertia principle (inertia fully governed by universe) and it is generalized to gravitationally quantum bound systems, resulting scale invariant fully relational dynamics (mere ordering upon actual objects), answering to rotation curves and velocity dispersions of the galaxies and clusters (large scale quantum bound systems), successful in all dimensions and scales from particle to … …Physics International, Vol. 11, Issue 1 · 10 Aug 2020 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractNondestructive Assessment of Egg Freshness using a Synchronous Fluorescence Spectral TechniqueJianhu Wu, Guifeng Li, Yankun Peng et al.Freshness is an important index of egg quality. In this study, a synchronous fluorescence spectral technique was employed to determine the freshness of an intact egg. Synchronous fluorescence spectra of intact eggs were acquired using a fluorescence spectrometer supported by a laboratory fluorescence acquisition device and egg freshness (Haugh Unit) was obtained using destructive methods. Eggs feature fluorescence signals were … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 19 Dec 2019 · 8,132 accessesView PDFCite
