https://www.selleckchem.com/products/phtpp.html A new tetrahedral structure model was developed for disordered sphere packings, including not only regular tetrahedron (T), but also quartoctahedron (Q) and bcc simplex (B), the tetrahedral building blocks in fcc, hcp and bcc crystal structures, respectively. Both geometric frustrated configurations and local configurations associated with crystalline order in disordered packings can be comprehensively characterized. It is found that with increasing packing fraction, the population of T, Q, and B increases. Moreover, the crystal-type local configurations formed by face-adjacent T, Q and B increases as packing fraction increases, which is more prevalent than the geometric frustrated ones formed by face-adjacent T. In addition, as packing fraction increases, the local density of irregular simplexes is found to increase more quickly than regular ones, playing more important roles in the density increase in disordered packings. These structure features are found to be intrinsic in the jammed random sphere packings with different friction coefficients, which is independent of interparticle friction and only determined by the packing fraction. Our findings provide new understanding for the structural nature of disordered packings and the underlying structural basis of the random close packing.NiO/AgNWs composite films which specially contain both porous and one-dimensional (1D) nanowire structures are prepared uniformly via a simple chemical bath deposition method. The supercapacitive electrodes constructed by the as-prepared NiO/AgNWs composite films exhibit a high specific capacitance (980 F g-1at 1 A g-1), much higher than that of the pure NiO films. Particularly, a large optical modulation (84.3% at 550 nm) and short switching times for the coloration and bleaching (5.4 and 6.5 s) are also observed if these NiO/AgNWs films serve as the electrochromic materials. The superior capacitive and electrochromic properties of the
