Bromine and Iodine Adsorption on an Fe ( 100 ) Surface

We studied bromine and iodine adsorption on an Fe(100) surface in the temperature range of 110 K to 700 K. In this communication we compare core-level binding energies of dissociatively and molecularly adsorbed halogen species as a function of coverage. Our valence band photoemission data suggest that bromine and iodine adsorption at 300 K is always dissociative. At 110 K, initial dissociative ...

Spectrophotometric Study of the Complexation of Iodine and Bromine with Tetrabutylammonium Halides and Cryptand 222 in Dichloromethane Solution

A spectrophotometric study concerning the interactoin between iodine and bromine with tetrabutylammonium iodide (TBAI), tetrabutyl- ammonium bromide (TBABr) and cryptand 222 (C222) has been performed in dichloromethane solution at 25°C. The results are indicative of the formation of TBA+X3- and  C222X+X3-  t...

Study on the effect of high calcium intake on serum protein bound iodine and urinary excretion of iodine

  Iodine deficiency remains a major health problem in the world, including some parts of Iran. It has been recognized that there is usually a close and inverse relationship between iodine in the soil and water and presence of endemic goiter. Calcium has been suggested as one of goitrogens, though the definite role, extent and mechanism particularly in human have not been studied. Serum protein-...

on the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors

the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
