application of polymers in novel and advanced scientific technologies is increasingly expanding. in this regard, optical polymers among different materials have found a special and unique position. a novel dye doped polymer thin film was prepared by taking advantage of dye molecules' interaction with the host environment. this sample, like self-assembled structures, makes use of this inter...

production of fe-c alloy powders by mechanical alloying was studied. fe and graphite elemental powdermixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. thestructural changes of powder particles during mechanical alloying were studied by x-ray diffractometery,scanning electron microscopy and microhardness measurements. for both compositions, mecha...

mulberry (morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, bombyx mori l. mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...
