Al-0.05Ga-0.05Sn-0.05Pb-xMg alloys with different Mg content have been prepared. Electrochemical tests including constant current discharge test, current polarization test, electrochemical impedance spectroscopy (EIS) test, and Tafel test are performed. The surface states of the alloys after constant current discharge were analyzed by scanning electron microscopy (SEM) and energy disperse spectroscopy (EDS). X-ray diffraction (XRD) analysis was carried out. We find that different Mg contents have great influence on discharge performance of aluminum alloy anodes by changing the corrosion behavior. The SEM and XRD show that Mg can influence the distribution of corrosion and change the grain size to improve the discharge performance of aluminum anodes. Al-0.05Ga-0.05Sn-0.05Pb-0.1Mg shows the best electrochemical performance due to uniform corrosion and proper grain size. At 800 mA cm−2 constant current discharge, the potential of the aluminum anode can reach − 1.54 V (vs Hg/HgO), and the utilization ratio is over 98%. [ABSTRACT FROM AUTHOR]

The FeSSe particles dispersed in the pores of carbon (FeSSe/PC) were prepared using a simple one-pot solid-state method, which were then characterized by XRD, SEM, TEM, XPS, and Raman spectrum techniques. As the anode material for lithium-ion batteries, FeSSe/PC displays an initial discharge capacity as high as 699.5 mAh/g at 0.1 C, and 327.9 mAh/g can be maintained after 200 cycles, much enhanced than those of pure FeSSe. The small particles of FeSSe wrapped in carbon can effectively buffer the volume expansion during charging/discharging to improve the electrochemical performance. [ABSTRACT FROM AUTHOR]

Five silver(I) complex of 4-amino-3,5-dipropyl-4 H-1,2,4-triazole (4-NH-3,5-Prtz) or 4-amino-3,5-dibutyl-4 H-1,2,4-triazole (4-NH-3,5-Butz), namely [Ag(4-NH-3,5-Butz)(NO)] ( 1), [Ag(4-NH-3,5-Prtz)(NO)](NO) ( 2), [Ag(4-NH-3,5-Prtz)](ClO) ( 3), [Ag(4-NH-3,5-Prtz)](CFSO) ( 4) and [Ag(4-NH-3,5-Butz)](BF) ( 5), have been prepared and structurally characterized by X-ray single crystal diffractions. Based on the structural data, a possible mechanism for the formation of Agtz cluster has been proposed, involving the formation of a dimer of dimer-(Agtz), followed by the replacement of counterions by two additional triazoles.

new approach was developed to prepare high-performance isobutylene-isoprene rubber/swollen organoclay nanocomposites by shear mixing. Compared with traditional melt compounding method, better dispersion of nanoclay layers in rubber matrix was verified through transmission electron microscopy (TEM) and X-ray diffraction (XRD). The nanocomposites also exhibit significantly improved mechanical properties and gas barrier property. As a mechanism, the molecules of organic swelling agent play a vital role in accelerating the diffusion and intercalation of the matrix molecules. [ABSTRACT FROM AUTHOR]
