“…L.O.I is the most widely used test to determine the resistance to ignition and the relative flammability of polymeric materials. It was measured by (ASTM:D-2863) method and calculated from the following equation [21]: residue, time to ignition, total smoke production, and heat release rate) of composites made of wood flour and high density polyethylene was studied. The addition of nanomagnesium oxide increased the ignition time and char residue, and it decreased the total smoke production, heat release rate, and burning rate, SEM and EDX pictures taken from samples including nanomagnesium oxide showed improper distribution and accumulation of nanomagnesium oxide, which weakened the mechanical features of nanocomposites [14].…”

This work aims to prepare magnesium oxide MgO nanopowder using the coprecipitation method and prepare nanocomposites by mixing MgO prepared nanopowder with epoxy resin by weight percentages (0.5, 1, 1.5, 2, and 2.5) using hand lay up molding. These prepared chemical materials are added to many consumer products to meet fire safety codes and prevent these items from catching fire quickly. If the flame retarded material or an adjacent material has ignited, the flame retardant will slow down combustion and often prevent the fire from spreading to other items. Especially some of these chemicals can accumulate in parts of electrical equipment, cars, airplanes, and building components. Using non toxic nanofillers in polymers to achieve flame retardancy is a viable option. The prepared powder has a cubic structure, space group, and 4.2165 Å unit cell parameters according to X-ray diffraction XRD data and using Dicvol 91 indexing program. The grain size of the prepared powder was measured using Sherrer's equation to be 12.45 nm. The scanning electron microscope SEM micrograph of MgO nanopowder showed a spherical shape. The effect of MgO on flame retardancy of epoxy resin was investigated using limiting oxygen index LOI, rate of burning RB, and maximum flame height HF tests. According to the results of the three standard tests, the best flame retardancy with a strong and well intumescent char is obtained from the sample with 2 wt. % of MgO nanopowder, which has the highest LOI value of 21.95, RB value of 1.65 cm/min, and HF value of 5.44 cm. This data of using MgO nanopowder as flame retardant was valuable and necessary because it showed MgO nanopowder help prevent and slow fires of epoxy resin, therefore, protecting property and saving lives.

Teknolojinin gelişmesiyle birlikte saf haldeki malzemelerin yetersiz kalmasından dolayı kompozit malzemeler geliştirilmiş ve zamanla kullanım alanları çoğalmıştır. Cam elyaf takviyeli polyester (CTP) kompozit malzemeler, iyi mekanik dayanım, elastiklik, yüksek korozyon dayanımı ve ekonomiklik gibi özelliklere sahip olmalarından dolayı dünyada yaygın kullanıma sahiptirler. Bu nedenle günümüzde CTP kompozitlere farklı takviye ve dolgu malzemeleri eklenilerek malzeme özelliklerinin geliştirilmesi amaçlanmaktadır. Bu çalışma sisal, jüt, kenaf vb. farklı doğal elyaf takviyesi ve cam kürecik, grafit, alümina vb. farklı dolgu maddesi kullanımının CTP kompozit malzemelerin özelliklerine etkisinin incelendiği çalışmaları ele almaktır. Çalışmanın ilk bölümünde genel olarak doğal ve cam elyaf takviyeli polimer kompozitler hakkında bilgi verilmiştir. Çalışmanın ikinci ve üçüncü bölümünde ise CTP kompozit malzemelerde kullanılan doğal elyaf takviyesinin ve dolgu maddelerinin malzeme özelliklerine etkisinin incelendiği çalışmalar sunulmuştur. Yapılan çalışmalarda doğal elyafların ve dolgu maddelerinin farklı üretim yöntemleriyle CTP kompozit malzemelere başarıyla dahil edilebildikleri, malzeme özelliklerini iyileştirici etki yapabildikleri ve maliyeti düşürebildikleri görülmektedir.

“…(2011), Sb showed high immunostimulatory effects and increased the capability of normal antigen to stimulate T cell in the Leishmaniasis treatment. Sb also has been used to compose substance as a reliable flame retardant (Dheyaa et al 2018). This ability is possibly useful for plants to reduce the effects of forest fire.…”

Abstract. Lianah L, Idris F, Krisantini K. 2019. Short Communication: Analysis of the chemical constituents and micromorphology of Bauhinia scandens using SEM-EDS techniques. Biodiversitas 20: 2055-2060. Some species of Bauhinia had a medicinal efficacy however the specific studies of Bauhinia scandens Willd. are relatively limited. Therefore this study analyzed the material and micromorphological characteristics of leaves, stems and roots of B. scandens using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) to quantitatively assess the elements and explore its potential uses. Samples of fresh plant were taken from five locations in Indonesia, and the results showed similar snake-like stem morphology from two locations, while pilot ladder-like stem morphology was observed from the other three locations. The material analysis revealed the presence of carbon, oxygen, silicon, potassium, indium, tellurium, aluminum and iron in the samples. Interestingly, the stems did not contain indium and aluminum whereas iron were only found in the roots. Furthermore, the young leaves did not contain tellurium and silicon. The presence of indium which is potential as a cancer drug in B. scandens suggests promising uses of the plant for herbal medicines.
