A novel energetic coordination compound [Co（DAT）6]（CIO4）2 has been synthesized by using 1,5-diaminotetrazole （DAT） as a ligand and its structure has been characterized using X-ray single crystal diffraction, elemental analysis and FT-IR spectroscopy. The central cobalt（II） cation is coordinated by six N atoms from six DAT molecules to form a six-coordinated and distorted octahedral structure. Di-dimension layer structure was formed by the extensive intermolecular hydrogen bonds between DAT ligands and CIO4 anions along a-axis and b-axis. Thermal decomposition mechanism of [Co（DAT）6]（CIO4）2 was investigated based on differential scanning calorimetry （DSC）, thermogravimetric analysis （TGA） and Fourier transform infrared （FF-IR） spectra. The kinetic parameters of the first exothermic process were studied by applying the Kissinger＇s and Ozawa-Doyle＇s methods. Additionally, the sensitivities of this complex were tested. The results of all the studies show that [Co（DAT）6]（CIO4）2 has an extreme potential application as an energetic material.

In order to understand the rate-controlling process for the interfacial layer growth of brazing joints brazed with active composite filler materials, the thickness of brazing joints brazed with conventional active filler metal and active composite filler materials with different volume fraction of AI2O3 participate was studied. The experimental results indicate although there are Al2O3 particulates added into active filler metals, the time dependence of interfacial layer growth is t2 as described by Fickian law for the joints brazed with conventional active filler metal. It also shows that the key factor affecting the interfacial layer growth is the volume fraction of alumina in the composite filler material compared with the titanium weight fraction in the filler material.

Microstructure and interracial reactions of Al2O3 joints brazed with Al2O3-particulate-contained composite Ag-Cu-Ti filler material were researched by scanning electron microscopy （SEM）, electron probe microscopy analysis （EPMA）, energy dispersive spectroscopy （EDS） and X-ray diffraction （XRD）. The interracial reaction layer thickness of joints brazed with conventional active filler metal and active composite filler materials with different volume fraction of Al2O3 particulate was also studied. The experimental results indicated although there were Al2O3 particulates added into active filler metals, the time dependence of interracial layer growth of joints brazed with active composite filler material is t^1/2 as described by Fickian law as the joints brazed with conventional active filler metal.

Failure-insensitive routing is a good mechanism to avoid packet dropping and disconnection of forwarding when some links fail, but multiple failure links may bring routing loop for the mechanism. Backtracking routing algorithm based on inverse shortest path tree rooted at destination is presented. The feasible restoration routing is obtained through searching from the start of the failure link and tracing back to the leaves of the shortest path tree with the destination as the root. The packets are forwarded from the mounted point with smaller sequence to the mount point with bigger sequence to decrease the possible of loop in case of multi-failures. The simulations and analysis indicate that backtracking routing algorithm improves the network survivability especially for large network, at the cost of the computation complexity in the same order as failure insensitive routing.

Oxygen evolution reaction(OER)is the imperative reaction for many energy storage and conversion devices such as recharge-able metal-air batteries and electrochemical water splitting[1].OER is a complex 4-electron process with sluggish kinetics and therefore requires electrocatalysts to overcome the high *** oxide(RuO_(2))and iridium oxide(IrO_(2))catalysts can promote the OER process remarkably[2-4],however,their ex-tremely high cost,natural scarcity,and long-term instability con-strain their scale-up application in clean-energy technologies[5,6].It is crucial to develop inexpensive,highly efficient,and durable electrocatalysts for OER.
