Research ArticleOpen accessIn the abstractPreparation of Rosemary Collagen Chitosan Blend Membrane Using Response Surface Methodology (RSM)Ming He, Yuhan Zhai, Yuqing Zhang et al.The present research provided a formula for the optimization of rosemary/collagen/chitosan blend membrane. Rosemary Extract (RE) was used as additive and membrane was prepared using tensile strength, elongation at break and elongation length as the indexes. The results of single factor experiment showed that the addition ratio of collagen to chitosan, additive content, glycerol content and drying temperature all affected … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 22 Nov 2021 · 6,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Bisphenol A Polyether Polyols on the Synthesis of Hydrophilic Epoxy ResinsJinhua Yi, Xin YuanThe article uses three types of Bisphenol A polyether polyols BEO, BPO-6 and BPO-10 as raw materials, reacts with epichlorohydrin under the action of a catalyst and synthesizes a hydrophilic epoxy resin. The molecular structure of the product is analyzed by infrared spectroscopy and the results show that the synthesis of the hydrophilic epoxy resin BEOGE conforms to the results … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 15 Jul 2021 · 7,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria. If there is … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 19 Apr 2021 · 7,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Collagen Casings with High Mechanical Properties using Response Surface MethodologyZhike Xie, Ming He, Yuhan Zhai et al.Usages of plastic casing have a number of drawbacks like generation of waste associated with the materials used to package foods and the source of natural casings is limited. So, the interest in the development of biodegradable collagen casing is increasing. For this reason, the present study aimed at developing a new type of collagen casing sprayed with Tea Polyphenols … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 16 Jan 2021 · 7,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractReinforcing Effect of Strain Gauges on 3D Printed Polymers: An Experimental InvestigationSalvatore Brischetto, Roberto TorreStrain gauges are ordinary transducers for strain measuring; their operation relies on the electrical resistance, which varies as the underlying substrate is subjected to mechanical deformation. The mechanical strain can be obtained by converting the electrical signal through a gauge factor, provided by the manufacturer. It was demonstrated that its values are not unique; it may be influenced by the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 7,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Antimicrobial Collagen Casings with High Mechanical PropertiesZhike Xie, Shuyan Yu, Ming He et al.Tea Polyphenols (TP) has received much attention for their excellent antioxidant and antibacterial activities. Some additives (such as sodium alginate and sodium pyrophosphate) have good hydrophobicity which have influence on the mechanical properties of food. The effect of TP on the antibacterial activity of collagen casing was investigated, the effect of addition of TP, sodium pyrophosphate and sodium alginate on … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 2 Sep 2020 · 6,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Using Crumb Rubber Modified Binder in an Asphalt PavementSayed Mohamad Soleimani, Alanoud Faheiman, Zainab MowazeIn this study, laboratory investigations have been carried out to characterize and demonstrate the improved performance of asphalt after modifying it with crumb rubber. The study has been divided into two main parts. Firstly, the physical characterizations of crumb rubber modified bitumen with different percentages of crumb rubber have been evaluated using penetration, softening point, viscosity, ductility and thin film … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 14 May 2020 · 8,384 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive Damage Modelling of Transverse Impact Behavior of Adhesively Bonded Composite JointsDimitrios Athinaios, Konstantinos Tserpes, Giannis FlorosA three-dimensional dynamic numerical model was developed, using the commercially available finite element software LS-DYNA to simulate the Low Velocity Impact (LVI) case on bonded joints consisting of woven CFRP adherents. The adhesive failure simulated using the Cohesive Zone Method (CZM), while the failures in the composite material simulated using a progressive damage material model based on Hashin’s failure criteria. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 3 Apr 2020 · 6,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Study of Self-Healing Concrete in Hot Desert ClimateBatoul Chamali, Moayyad Al-Nasra, Taher M. Abu-LebdehThe hot and dry desert climate is characterized by high temperature and high humidity. This affects the strength of concrete negatively by the difficulty of providing proper curing and by generating early micro-cracks due to the high temperature. These two issues have been addressed in this study by adding calcite precipitating bacteria to deal with the micro-cracks and by adding … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 16 May 2019 · 8,047 accessesView PDFCite
