“…The reaction order and activation energy of the desinsertion reaction was estimated by the method of Borchardt and Daniels. 25 Reaction enthalpies and activation energies were corrected for the actual amount of Sb x CoSb 3Àx present in the samples, as determined by Rietveld analysis of their x-ray diffraction patterns. Electrical resistivity was measured using a fourpoint technique suitable for cylindrical samples with high thickness-to-diameter ratio.…”

“…Anhydrous alkali metal oxalates M 2 C 2 O 4 form an interesting group of compounds with very similar layered crystal structures and well-defined oxalate anions as an independent entity surrounded by metallic cations, decomposing thermally-unlike transition metal oxalates-via two step process with respective carbonate as transition product [1][2][3][4][5][6][7][8][9][10][11][12]:…”

The results of first principles calculations of band structure, density of states, and electron density topology of alkali metal oxalates are presented. The calculations have been carried out with WIEN2k ab initio program, using highly precise full potential linearized augmented plane wave method within density functional theory formalism. Calculated total electron density has been used in calculations of its topological properties (according to Bader's quantum theory of atoms in molecules formalism) and Cioslowski and Mixon's topological bond orders. The obtained results show important similarities between electronic structure and electron density topology for all analyzed structures with electronic structure close to Fermi energy typical for ionic compounds and bonding which is mainly covalent within the oxalate anion (with partly ionic character of carbon-oxygen bonds) and strongly ionic between oxalate anion and cationic sublattice. These results have been used as a basis for theoretical analysis of thermal decomposition process described in detail in part II of this paper (where also the results of additional calculations of atomic and bond valences, bond strengths and strains are presented).

“…As it is well known, the reaction between epoxies and amines involves several steps [41][42][43], and hence the mechanism may be rather complex. Without knowing the exact reaction mechanism, it is reasonable to assume that the kinetic parameters of the curing process can be determined by Borchardt and Daniels method [44], in which the reaction rate at a given time t is a function of the conversion fraction α, or…”

Non-isothermal dielectric analysis (DEA) and differential scanning calorimetry (DSC) techniques were used to study the epoxy nanocomposites prepared by reacting 1, 3,5,7,9,11,13,15-octa[dimethylsiloxypropylglycidylether] pentaciclo [9.5.1.1 3,9 .1 5,15 .1 7,13 ] octasilsesquioxane (ODPG) with methylenedianiline (MDA). Loss factor (ε") and activation energy were calculated by DEA. The relationships between the loss factor, the activation energy, the structure of the network, and the mechanical properties were investigated. Activation energies determined by DEA and DSC, heat of polymerization, fracture toughness and tensile modulus show the same profile for mechanical properties with respect to ODPG content.
