Electrospun polycaprolactone nanofibers functionalized with Achillea millefolium extract yield biomaterial with antibacterial, antioxidant and improved mechanical properties
(John Wiley and Sons Inc., 2023)
In this study, polycaprolactone (PCL), as a biocompatible polymer was functionalized by addition of medicinal plant extract- Achillea millefolium L. (yarrow). Nanofiber mats were fabricated from PCL solutions containing ...
Effect of surface activation of alumina particles on the performances of thermosetting-based composite materials
(Sage Publications Ltd, London, 2019)
Two types of alumina particles, commercial (c-Al2O3) and iron doped (Fe-Al2O3), were functionalized with 3-(aminopropyl)trimethoxysilane (one-step) and two-step consecutive process, i.e. firstly using 3-(aminopropyl)trim ...
Fracture micromechanisms in overaged 7000 alloy forgings
(Journal of Alloys and Compounds, 2007)
Micromechanisms controlling the fracture damage in 7000 alloy forgings are studied for T73-type heat treatments. Insight into the fracture modes are obtained by varying the microstructural attributes associated with the ...
Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
Mechanical properties of acrylate matrix composite reinforced with manganese-aluminum layered double hydroxide
(John Wiley and Sons Inc., 2023)
Acrylate polymers are used in several applications such as dentistry, medicine, and industry. The modification of their properties using the reinforcement is of key importance for the possible applications. Layered double ...
The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper
(Journal of Natural Fibers, 2022)
This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use ...
Wash-dry cycle induced changes in low-ordered parts of regenerated cellulosic fibers
(Wiley-Blackwell, Hoboken, 2012)
Three regenerated cellulosic fiber types: lyocell, viscose, and modal were subjected to repetitive wetdry treatments. Simulated treatments showed reorganization of the internal fiber structure which could be determined by ...
Dissimilar sintered calcium phosphate dental inserts as dentine substitutes: Shear bond strength to restorative materials
(Wiley, Hoboken, 2020)
The application of sintered calcium phosphate dental inserts in the central part of tooth cavities can reduce amount of embedded dental composite and polymerization shrinkage of final dental fillings. The aim of this study ...
Reuse potential of functionalized thermoplastic waste as reinforcement for thermoset polymers: Mechanical properties and erosion resistance
(SAGE Publications Ltd., 2021)
Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the ...
Denture composite reinforced with short polyethylene terephthalate fibers
(John Wiley and Sons Inc., 2022)
Polymer matrix composite materials have found application in dentistry because of good mechanical properties, aesthetic, easy processing, and possibilities of the repair. Acrylates are materials used to make and repair ...
