چکیده
Article Info The aim of this study is to investigate the contents of essential, macro and micro elements by the energy-dispersive X-ray fluorescence spectrometry (EDXRF) in different seaweeds (10 red algae, 5 green algae)from collected different regions of Visakhapatnam coast(India). Seaweeds from different estuarine stations were analyzed by X-ray fluorescence, providing results for the concentration of total K, Ca, Mo, Mn, Fe, Co, Ni, Cu, Zn, I, Na, Mg, Se and P. A radioisotope excited X-ray fluorescence analysis using the method of multiple standard additions was applied for the elemental analysis of seaweed samples. The results demonstrated that these seaweeds contain some essential element, but no toxic element. Edible green and red seaweeds could be used as a food supplement to help meet the recommended daily intake of some essential minerals and trace elements. Energy-dispersive X-ray fluorescence has been shown to be a suitable technique for multi-element analysis in this type of sample. No chemical pretreatment is required, minimizing sample contamination. The small amount of sample required, and the wide range of elements that can be detected simultaneously make energy-dispersive X-ray fluorescence a valuable tool for micro and macro elements analysis.

Evidence of the Potential Shift Mechanism in Crevice Corrosion (RESEARCH NOTES)
Previous research has indicated a qualitative resemblance between the current distribution along actively corroding crevice walls and currents measured in corresponding anodic polarization plots. Using detailed measurements of the potential gradient along the crevice, a semi-quantitative current distribution was calculated for the crevice wall using a double numerical differentiation method. Th...

Carbon nanoscrolls (CNSs) belong to the same class of carbon-based nanomaterialsas carbon nanotubes. As a new category of quasi one dimensional material Graphene Nanoscroll (GNS) has captivated the researchers recently because of its exceptional electronic properties like having large carrier mobility. GNS shape has open edges and no caps unlike Single Wall Nanotubes (SWNTs) which are wou...
متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
