Complexes of 3d Metals with Coordination Number Seven and Macrocyclic 2,6-Diacetylpyridine and Some Related 

6CTP (capped trigonal prism) complexes all the others are the PBP (pentagonal-bipyramidal) complexes. 

For the synthesis of the Co(II) complex with H2dapsox, direct and template methods were employed, which afforded an identical product 1

As far as electron absorption spectra of the Co(II) PBP complex are concerned, they have still been insufficiently explained (1,56,67,86). Gerloch et al. (86) discussed the spectra of the [Co(H2dapsc) (C1)(H20)] and [Co(H2dapsc)(H20)2] cations in some detail and the bands at 632, 562, 549(sh), and 507(sh) nm of the former, and those at 628, 540, and 526(sh) nm of the latter complex, were ascribed to transitions between components of the P term. These authors found that all spin-allowed d-d transitions occur at energies below 500 nm.

Brief review of different aspects studied and various methods used... 

In ceria-based catalysts, one main aspect studied with XPS is the cerium redox state (i.e. the proportion of Ce and Ce " ) for different preparations or treatments. Peak u, located at Eb==916.5 eV, which appears to be typical of and absent for Ce, and consequently decreases upon reduction, has been used frequently with this...

Recent fundamental studies of physisorption by nonporous carbons have involved the application of molecular simulation [23, 29], density functional theory, and lattice gas models [30]. Important aspects studied have included the way in which the molecular packing in each layer is likely to be affected by a systematic alteration of the lattice parameters and interaction energies and the resulting changes in the isotherm shape [21, 30]. 

In ceria-based catalysts, one main aspect studied with XPS is the cerium redox state (i.e. the proportion of Ce and Ce " ) for different preparations or treatments. Peak u, located at Eb 916.5 eV, which appears to be typical of Ce and absent for Ce, and consequently decreases upon reduction, has been used frequently with this aim. The percentage %(u ) of the total integrated spectrum intensity (after baseline subtraction) lying within this peak in pure, nonreduced Ce02 has been computed to amount to 13.7% [108]. The %(u ) value of an analyzed material is frequently used in the literature to quantify its redox state, assuming e.g. that the the quotient betwen it and the value for Ce02 gives the fraction of Ce in the material. It has been however pointed out in early works [109], that this value is not proportional to the amount of Ce present specifically Romeo et al. [110] claimed that peaks v... 

Tribological effects can have both positive and negative effects, both of which are crucial to the functioning of modern machinery. The applied science of tribology is a multi-aspect study that seeks first to identify the genesis of tribological effects. It then seeks to identify the ways in which negative effects can be reduced or eliminated and positive effects used or enhanced.

Even today in the United States there are about 13 deaths daily in the workplace and 4 million injuries per year (Barab, 2012), which means we have to better integrate system safety into all engineering aspects. Studies conducted at Stanford University estimate the cost of accidents for nsers of conunercial and industrial construction at 1.6 billion annually. Hidden costs were found to be two to 18 times higher. Researchers also found that construction safety research over a 10-year period showed irrefutable... 

The ROP of TMC initiated with several alcohols was examined by Endo s group.It was found that the reactions proceeded without acidic catalyst in low conversions. However, when the polymerization was carried out in the presence of alcohol/trifluoroacetic acid (ROH/TFA) catalyst system the corresponding PCs with Mn = 2500-6800 were formed. The molecular weights increased with an increase of the monomer conversion. Mechanistic aspects studied by NMR spectroscopy indicated that carbonate rings are activated by TEA. The signals of the methylene protons shifted to lower fields by 0.06-0.11 ppm in the NMR spectra after the addition of TEA. Downfield shifts of the carbonyl carbon atom signals in TMC were observed by 3.94-4.15 ppm in the C NMR spectra.
