Figure 3(a) shows a temperature dependence ofthe fiber output and monitor current for one of the fabricated 50 samples of the plastic module. The fiber output was 0.2 mW in the full operating temperature range from -40-85°C. The monitor current was >lo0 (*.A at 0.2 mW fiber output and the trackingwidth of < + -20% was obtained in the full temperature range. The rise and fall time ofthe transmit...

Potassium methyl siliconate (PMS) was investigated as a new nano modifier of wood fiber and wood flour to improve the compatibility between the fiber/flour and the plastic matrix in fiber reinforced plastic composites. Before injection molding, bleached and brown pulp fibers and mixed species wood flour were pretreated in PMS solutions. The morphology of the treated and untreated fiber and flou...

Interfacial strength between polymeric matrix and natural filler reinforcement has direct effects on the properties of wood plastic composites. There are some approaches to improve the interfacial adhesion between two phases in wood plastic composites. One of them is using coupling agents to improve the composite properties. In this study, the effect of maleic anhydride as a coupling agent on t...

BACKGROUND Unlike congenital auricular malformations which are identified by underdevelopment of dermal and cartilaginous tissues, deformed ears are less sever congenital anomalies characterized only by a misshaped pinna structure and can be improved with acceptable cosmetic results and minimal cost through ear molding if treated in early neonatal period. In this study, authors present the f...
