Research ArticleOpen accessEvery word in the titleStudy the Relationship between the Microstructure and Characteristics of Quinoa Starch by Compared with Common Cereal StarchesMenyue Jiao, Yumei Gao, Yiling TianThe amylose and amylopectin contents, viscoelastic properties, freeze-thaw stability and Scanning Electron Micrographs (SEM) of quinoa (Chenopodium quinoa Willd) were studied to explore the microstructural property relationships. Compared with wheat, corn, rice and waxy rice starches, quinoa starch had special characteristics connected to its unique microstructure. The high ratio of amylopectin to amylose (12.03) in quinoa starch affected its functional … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 17 Dec 2020 · 7,256 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Acid Frosting on the Microstructure Characteristics and Mechanical Strength of Eroded Soda-Lime-Silica Glasses by SandstormAkinwumi Gbenga Owoyemi, Grace Olufunke Matthew, Seun Samuel OwoeyeMost glass products such as cars windshields, solar panels protecting glass and windowpanes are exposed to unavoidable sandblasting effects especially in areas prone to sandstorms. This sand impingement results into micro cracks and surface flaws which altered the structure and strength of the exposed glasses thereby lowering their service life. In this regard, attempt was made in this research to … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 25 Apr 2019 · 6,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement ProductionMohd Sobri Idris, Khairul Nizar Ismail, Shamsul Baharin Jamaludin et al.Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of α±-belite at higher temperature (around 1300°C), then … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,498 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA COSSERAT-TYPE PLATE THEORY AND ITS APPLICATION TO CARBON NANOTUBE MICROSTRUCTUREAbdellatif Selmi, Hedi Hassis, Issam Doghri, Hatem ZenzriThe predictive capabilities of plate and shell theories greatly depend on their underlying kinematic assumptions. In this study, we develop a Cosserat-type elastic plate theory which accounts for rotations around the normal to the mid-surface plane (so-called drilling rotations). Internal loads, equilibrium equations, boundary conditions and constitutive equations are derived. The case of a Single Walled carbon Nanotube (SWNT) modelled … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 12 May 2014 · 6,930 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCrack Bridging and Deflection Toughening Mechanisms of Staggered Hydroxyapatite Lamellar Microstructure in BoneYuxi Liu, Xiaohui He, Shuge Li, Zhangdong SunThe observation experiment results of the microstructure of tibial cortical bone show that the cortical bone is a layered bio-ceramic composite material composed of Hydroxyapatite (HAP) and collagen arranged alternately. HAP is a reinforcing phase and accounts for a large proportion in cortical bone. These hydroxyapatites have long and thin sheet-like structures parallel to the outer surface of the bone, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 31 Jul 2026 · 890 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMicrostructure Affecting Cutting Quality in Fine Blanking ProcessBopit BubphachotProblem statement: Fine blanking process is a high precision process and worldwide in developed countries. Since specimen does not occur fracture on the cutting edge and it is not necessary to decorate again in the finishing process for the fine blanking which can be reduced some operation steps. For example, if chain wheel of motorcycle is produced by conventional blanking, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,455 accessesView PDFCite
