Research ArticleOpen accessIn the keywordsMechanism of Microencapsulation with Urea-Formaldehyde PolymerRochmadi, Agus Prasetya, Wahyu HasokowatiProblem statement: Microcapsule is one of important fine chemical products in the current chemical industries. Better understanding of microencapsulation process is useful to properly design of microcapsule with specific characteristics. The aim of this research is to study the mechanism of Urea-Formaldehyde (UF) microcapsules formation. Approach: Microcapsule was prepared in two steps. The first step was the preparation of oil … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Fluorine/Silicon Co-Modified Elastic Acrylate with Low Fluorine and High PerformanceYuan Zhihua, Xia Chunlei, Geng Ziye et al.The methyl acrylate was modified with hexafluorobutyl methacrylate (G02) and vinyl triethoxy silane (A-151) as modified monomers, Methyl Methacrylate (MMA) as hard monomer and Butyl Acrylate (BA) as soft monomer. Pre-emulsification, seed emulsion and semi-continuous synthesis process were adopted to the effects of the preparation process, the ratio of G02 and A-151 modified monomers, the amount of soft monomer and … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 4 Jan 2020 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmobilization of Lipase from Candida Rugosa on Palm-Based Polyurethane Foam as a Support MaterialRoila Awang, Mohd Rafaei Ghazuli, Mahiran BasriLipase from Candida rugosa was immobilized onto palm-based polyurethane foam (PU), which the polymer was pre-soaked in co-immobilized agent. The activities of PU-immobilized lipase were tested by the esterification reaction of oleic acid and oleyl alcohol in hexane. The PU-immobilized lipase was then characterized in term of its thermal, operational and storage stability. The optimum temperature for native and PU-immobilized … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,478 accessesView PDFCite

Research ArticleOpen accessIn the abstractMomordica balsamina Fruit Extracts Enhances Selected Aspects of the Insulin Synthesis/Secretion PathwayAnanias Hodi Kgopa, Leshweni Jerry Shai, Motetelo Alfred MogalePrevious studies have suggested that crude plant extracts of the anti-diabetic medicinal plant, Momordica balsamina (MB) may exert their anti-diabetic effect through either enhancement of insulin sensitivity or inhibition of intestinal glucose absorption. However, the effects of these MB extracts on insulin synthesis and secretion are not well documented in the literature. Therefore, a main purpose of the current research … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 17 Dec 2020 · 6,999 accessesView PDFCite
EditorialOpen accessIn the abstractVolume 3: SGAMR is Always on Track!Chiara Bedon, Mario D’Aniello, Flavio StochinoThe year 2019 represents a new growing step for SGAMR, that starts to publish “continuously” all the accepted papers, once they are subjected to positive, blinded peer-review process. This is a further effort to improve the service for the contributors and for the readers, given that the efficiency of the journal to share knowledge can be maximized. Hänig et al. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 28 Aug 2020 · 5,711 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Properties of a Dispersant Used for Extracting Oil with High Gas-Oil RatioVladimir Verbitsky, Aleksey Dengaev, Oleg Zubkov, Dmitry KoshkinThe article presents the bench test results for a dispersant manufactured by Izhnefteplast Company, which specializes in batch production of unique submersible pumping equipment for oil extraction. The submersible equipment is unique in that the working elements of the pumping equipment are made of polymeric materials unlike the conventional concept of pumping machinery for oil production. The relevance of the … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 24 Feb 2016 · 7,293 accessesView PDFCite
Research NotesOpen accessIn the abstractPolymerisation and Oxidation of Docosahexaenoic AcidBrian Mundell Ross, Shelly Lynn Browning, Adrian McKeeOils rich in polyunsaturated fatty acids, such as linseed oil, can oxidise to form polymers. These can be used as protective coatings and act as an alternative to those derived from petrochemicals. Such renewable source oils usually require the addition of metal ions as catalysts of the polymerisation process and/or the partial pre-oxidation of the oil before use. We hypothesised … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 11 Dec 2015 · 7,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractHypoxia-Inducible Factor 1α Expression in Chorionic Tissue and Decidua of Women with Spontaneous Abortion at the First Trimester of PregnancyE. V. Mashkina, K. A. Kovalenko, E. V. ButenkoOxygen-regulated genes expression has important role in pre-implantation embryonic metabolism regulation. Hypoxia Inducible Factor (HIF) regulated by hypoxia oxygen tension is crucial for placenta development. But the data about its role in spontaneous abortion is very poor. Thus, we aimed to determine an expression level of HIF-1α in chorionic tissue and decidua at pregnancy. Samples of chorionic tissue and decidua … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 18 Nov 2014 · 6,862 accessesView PDFCite
