چکیده

A Ni-Cu ion exchange has been observed for (5,15-dibromo-10,20-diphenylporphyrinato)nickel(II) (NiDBrDPP) and (5,10,15,20-tetrakis(4-bromophenyl)porphyrinato)nickel(II) (NiTBrPP) on Cu(111). The ion exchange proceeds at a faster rate for the NiDBrDPP/Cu(111) system compared to NiTBrPP/Cu(111). This is explained in terms of the macrocycle-substrate distance and the distortions that occur when the molecules are deposited on the Cu(111) surface.

Selective Sorption of Heavy Metal Ions from Aqueous Solutions Using m-Cresol Based Chelating Resin and Its Analytical Applications

Salicylic acid-Formaldehyde-m-Cresol (SFM) terpolymer had been synthesized in DMF media by conventional method. The resulting resin had been characterized by FTIR spectra, elemental and thermogravimetric analyses. The morphology of SFM resin had been studied by SEM and Optical photograph. Various parameters like rate of equilibration, effect of pH on ion exchange capacity and effect of conc...

Exchange interaction of strongly anisotropic tripodal erbium single-ion magnets with metallic surfaces.

We present a comprehensive study of Er(trensal) single-ion magnets deposited in ultrahigh vacuum onto metallic surfaces. X-ray photoelectron spectroscopy reveals that the molecular structure is preserved after sublimation, and that the molecules are physisorbed on Au(111) while they are chemisorbed on a Ni thin film on Cu(100) single-crystalline surfaces. X-ray magnetic circular dichroism (XMCD...

Conversion of Soybean Oil into Ion Exchange Resins: Removal of Copper (II), Nickel (II), and Cobalt (II) Ions from Dilute Aqueous Solution Using Carboxylate- Containing Resin

An ion-exchange resin containing carboxylic acid groups was prepared by reaction of epoxidized soybean oil with triethylene tetramine, followed by hydrolysis of glycerides by using sodium hydroxide solution. The cation exchange capacity of the resins was determined to be 3.50 mequiv/g. The adsorption capacity for Cu , Ni , and Co on the obtained resin at pH 5.0 was found to be 192, 96, and 78 m...

First-principles study of methane dehydrogenation on a bimetallic Cu/Ni(111) surface.

We present density-functional theory calculations of the dehydrogenation of methane and CH(x) (x=1-3) on a Cu/Ni(111) surface, where Cu atoms are substituted on the Ni surface at a coverage of 14 monolayer. As compared to the results on other metal surfaces, including Ni(111), a similar activation mechanism with different energetics is found for the successive dehydrogenation of CH(4) on the Cu...

SURFACE MAGNETISM OF THE CLEAN Ni (111) SURFACE AND OF A Ni MONOLAYER ON Cu (111)

Results of highly precise all-electron local spin density FLAPW calculations on (i) a close-packed 7-layer Ni (111) slab and (ii) a p (1 x 1) Ni monolayer on Cu (111) are presented. For Ni ( I l l ) , we find an enhancement of the magnetic moment for both the surface (to 0.63 pB) and sub-surface Ni layers (from a center layer value of 0.58 pB). In contrast, a slight decrease of the magnetic hyp...
