INDIRECT INTERACTIONS OF H/Ni(lll) AND H/Pd(lOO) USING EMBEDDED ATOM METHOD
Using the embedded atom method (EAM), we computed lateral interactions between H atoms on Ni(ll1) and on Pd(100). For H/Ni(lll) the binding-energy difference between the two 3-fold sites is very small. As expected due to the very small separation, at nearest neighbor sites there is an extreme repulsion. The only other non-negligible interactions are repulsions of comparable size (a few mev) bet...
متن کاملConductance of Pd-H Nanojunctions
016802-1 Results of an experimental study of palladium nanojunctions in a hydrogen environment are presented. Two new hydrogen-related atomic configurations are found, which have conductances of 0:5 and 1 quantum unit (2e2=h). Phonon spectrum measurements demonstrate that these configurations are situated between electrodes containing dissolved hydrogen. The crucial differences compared to the ...
متن کاملIn Vitro Flower Production in Some Species of Hyoscyamus (H. pusillus L., H. arachnoideus Pojark, and H. niger L.)
Various plant organ segments including segments from roots (root tip, and root collar), stems, leaves, and also seeds of several Hyoscyamus species (i.e. H. pusillus, H. arachnoideus, annual and biennial H. niger from two distinct geographical regions) were cultured on MS media with various growth regulator combinations, to assess the ability of flower production. Statistical assessments showed...
متن کاملPREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared
We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...
