Research ArticleOpen accessIn the abstractThe Diversity of Fungi in Landfill and their Potential to Degrade PlasticErman Munir, Yitro Pasaribu, Syahira Mubtasima, Ahmad Faisal NasutionPlastic has been known as a recalcitrant material and is very difficult to degrade in nature, resulting in its accumulation and threatening the environment if it is not managed properly. Studies on the degradation of plastics have been obtaining much attention recently. This study aimed to determine the diversity of fungi isolated from plastic wastes in landfills and to identify … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 1 Mar 2024 · 6,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptoelectronic Characterisation of Silicon and CIGS Photovoltaic Solar CellsRicardo A. Marques Lameirinhas, Afonso Ravasco, Catarina Pinho Correia Valério Bernardo, João Paulo N. TorresThroughout these years, many materials have been subjected to tests and experiments, creating several photovoltaic technologies and generations. In this article, some of these generations are compared, namely silicon and Copper Indium Gallium di-Selenide (CIGS), in order to characterize both materials in an optoelectronic way. Using a 2D solar cell PIN model using COMSOL software, both materials are tested, obtaining … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 1 · 30 Jan 2024 · 4,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Properties of Biopolymers from Corn Starch with Addition of Microalgae Spirulina platensisJúllia Koury Abreu, Loraynne Coelho Pereira, José Izaquiel Santos da SilvaThe discovery of the environmental impacts caused by petroleum-based polymers has led to the use of natural polymers gaining more and more space. Naturally occurring polymers, also known as biopolymers, are chemical compounds produced by living things or raw materials from renewable energy sources. Their main advantage is decomposition, while polymers from fossil and non-renewable energies can take hundreds of … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 1 · 16 Mar 2023 · 6,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractGreen Synthesis of Silver Nanoparticles using Extract of Disporopsis Longifolia for Photocatalytic Degradation of Methylene BlueKhieu Thi Tam, Dang Van Thanh, Huu Tap Van et al.In this report, the silver Nanoparticles (AgNPs)were successfully synthesized in a simple one-pot method by the leaf and stemextract of Disporopsis longifolia as reducing, capping agents, andstabilizers for the first time. The optimal extract amount, AgNO3concentration, reaction temperature, and time for the AgNPs synthesis wereidentified using Ultraviolet-Visible (UV-Vis) spectroscopy. X-Ray Diffraction (XRD)and Scanning Electron Microscopy (SEM) were used to characterize … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 23 Nov 2022 · 6,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction Optimization and Antibacterial Property of Total Flavonoids from Zizania Latifolia Bracts and the Effect on Chilled Pork PreservationChen Pan, Shuyi Zhu, Na Niu et al.Zizania latifolia isa widely distributed aquatic vegetable, and its bracts are an agriculturalwaste with a large proportion. In this study, Total Flavonoids of Z. latifoliaBracts (TFZB) were extracted with Ultrasound-Assisted Enzymatic Extraction(UAEE) for the first time, and the extraction process was optimized usingResponse Surface Method (RSM), and compared with other methods. Then, theantibacterial activity of TFZB extracted with optimized UAEE … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 15 Sep 2022 · 6,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Response Surface Methodology for Optimization of Nickel Adsorption in an Aqueous Solution by ClayNesrine Turki, Nesrine Boujelben, Zaineb Bakari, Jalel BouzidIn this study, Scanning Electron Microscopy (SEM), X-ray diffraction and BET surface area (SBET) methods were employed to characterize the adsorbent. Response Surface Methodology (RSM) was consider as a good method to assess Ni adsorption treatment and Box-Behnken design was used to examine simultaneous the effects of different experimental variables (pH, adsorbent dosage, contact time). Experimental results showed high adsorption … …American Journal of Environmental Sciences, Vol. 17, Issue 5 · 24 Nov 2021 · 6,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtective Role of Chichorium intybus Extract Against Renal Toxicity Induced by Magnetite Silver Nanoparticles in Male RatsDoha M. Beltagy, Ehab Tousson, Nabiha I Abdo, Batoul M. IzzularabMagnetite silver nanoparticles (Fe3O4/AgNPs) symbolize a new candidate in several industrial and biological products for their activities, simple preparation and low synthesis costs. Many studies recommended the usage of Fe3O4/AgNPs to overcome lacking biocompatibility of AgNPs inside the body. However, Fe3O4/AgNPs also has toxic effects on kidney tissues. In this study, AgNPs was synthesized on the surface of magnetic nanoparticles … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 15 Sep 2021 · 6,318 accessesView PDFCite
