Other analyses performed are VSM measure the magnetic properties SEM determine...
Abstract Iron sand-based Fe 3 O 4 nanoparticles–polyvinylidene fluoride (PVDF) nanofibers were processed inside an electrospinning system at room temperature. The incorporation of nanoparticles into the PVDF matrix decreases diameter fibers. presence crystalline phase in electrospun PVDF-Fe fiber indicates unchanged crystal structure. surface morphology samples was altered considerably after and heating processes. Infrared spectroscopy identification confirmed α to β -phase transformation...
Now days, heavy metal pollution has become one of the most serious environmental problems. The magnetic nanoparticles (MNPs) have received great attention to solving problems as adsorbent materials due their unique physical and chemical properties. CoFe2O4 MNPs was prepared by co-precipitation method, its application for removal Cu(II), Fe(II) Ni(II) ions from wastewater. various structural well morphological properties were characterized x-ray diffraction (XRD), transmission electron...
Understanding the evolution of magma storage conditions on volcanoes which have had more than one caldera-forming eruption (CFE) is important to know about past and present conditions, as a key forecast future potential hazards. Krakatau volcano characterized by cyclic phases growth destruction edifice. A volcanostratigraphic study identified three eruptive periods: Old Krakatau, Young Anak Krakatau. The periods ended with first second CFE respectively. Due its permanent activity edifice...
