The molten salt activation containing different oxysalts are proposed to activate the ordered mesoporous carbons loading on graphene layers (OMC/G). The effects of different oxysalts activations on the structures of OMC/G are thoroughly investigated by scan electron microscopy (SEM), small angle X‐ray scattering (SAXS), Raman spectroscopy and nitrogen adsorption‐desorption at 77 K. The structures of these carboneous materials are related with the oxidizing nature of these oxysalts. By using weak oxysalt of K2CO3, the original structure of OMC/G is almost kept together with the appearance of a lot of micropores and mesopores. The electrochemical performances of OMC/G after different oxysalts activation are also studied for supercapacitor applications. OMC/G after weak oxysalt of K2CO3 based electrode results in the highest specific capacitance up to 332.5 F g−1 at a current density of 1.0 A g−1, which is higher than those after both KOH activation (276.8 F g−1) and the other three oxysalts activation. Moreover, OMC/G‐K2CO3 shows an excellent cycling stability with no capacitance loss over 5000 cycles. The molten salt activation would be potentially applied to activate the porous carbons for supercapacitor applications.

Filamenting temperature-sensitive mutant Z (FtsZ), an essential cell division protein in bacteria, has recently emerged as an important and exploitable antibacterial target. The perturbation of FtsZ assembly is found to have an effect on cell cytokinesis and cell survival. Cell division time is an important physical parameter in cell cytokinesis. Here, the theoretical framework that has been developed by combining a phase field model for rod-shaped cells with a kinetic description for FtsZ ring maintenance is extended to explore cell division times during bacterial cytokinesis. The cell division times of around 72 s in the numerical studies have the same magnitude as the division time of several minutes observed physiologically. The dependence of the cell division time on parameters such as the initial state of rod-shaped cells and various kinetic rates of FtsZ assembly dynamics is thoroughly investigated. The theoretical analysis of the relations between the cell division time and these parameters is found to coincide well with the numerical calculated results.

Cell morphodynamics during bacterial cytokinesis are theoretically explored by a combination of phase field model for rod-shaped cells and a kinetic description for FtsZ ring maintenance. The division times and cell shapes have been generally decided by the competition between the constriction forces generated by FtsZ rings and the curvature elastic energy for cells. The dependences of cell morphodynamics during bacterial cytokinesis on various kinetic rates of FtsZ filaments are focused in the present study. It is found that the obtained results with the experimental parameters are well comparable to the observed results physiologically. Likewise, the quasi-steady states for FtsZ rings are found to be well consistent with the theoretical results derived from the kinetic description of FtsZ rings. In addition, morphological phase diagram is presented as functions of the membrane associate rate for both short FtsZ filaments and free FtsZ monomers, and the depolymerization rate of GDP-bound FtsZ monomers at the tip of filaments within the ring. Our results would provide a better understanding of the details of in vivo kinetics, including the kinetic rates within FtsZ rings.

TiO2 composite photocatalytic film was prepared on steel by plasma electrolytic oxidation in aluminate electrolyte. The microstructure of the composite film was investigated by XRD and SEM. The photocatalytic properties of the films treated with different time were studied by photocatalytic degradation of Rhodamine B with various irradiation time. The results revealed that the as prepared film was composed of crystal phase of much A-TiO2 and a little γ-Al2O3. The film surface was rough and porous. The pores are in the dimensions of 2-8 μm. The photocatalytic experimental results showed that for the same irradiation time, the removal ratio of Rhodamine B of the films gradually increased with increasing the treating time. For each film, the removal ratio of Rhodamine B of the film also gradually increased when increase the irradiation time. The 30 min treated sample exhibited a removal ratio of 80% in 2h irradiation of ultraviolet light.
