We report a novel slurry electrolyte with ultrahigh concentration of insoluble inorganic lithium metasilicate (Li2SiO3) that is exploited for lithium ion batteries to combine the merits of solid and liquid electrolytes. The safety, conductivity, and anodic and storage stabilities of the eletrolyte are examined, which are all enhanced compared to a base carbonate electrolyte. The compatibility of the elecrolyte with a LiNi0.5Mn1.5O4 cathode is evaluated under high voltage. A discharge capacity of 173.8 mAh g-1 is still maintained after 120 cycles, whereas it is only 74.9 mAh g-1 in the base electrolyte. Additionally, the rate capability of the LiNi0.5Mn1.5O4 cathode is also improved with reduced electrode polarization. TEM measurements indicate that the electrode interface is modified by Li2SiO3 with a thinner solid electrolyte interphase film. Density functional theory computations demonstrate that LiPF6 is stabilized against its decomposition by Li2SiO3. A possible path for the reaction between PF5 and Li2SiO3 is also proposed by deducing the transition states involved in the process using the DFT method. © 2015 American Chemical Society.

Purpose - The purpose of this paper is to propose a new four-node membrane element model with bending modification based on the equilibrium principle of element nodal internal forces and bending moments for the application of the one-step algorithm for bus rollover collision. And it can be concluded whether the proposed four-node membrane element model has practical value in engineering application or not. Design/methodology/approach - Based on the equilibrium principle of element nodal internal forces and bending moments, the paper puts forward a four-node membrane element model with bending modification. A case study on the rollover of a typical bus body section is carried out by using the onestep algorithm for bus rollover collision to verify the effectiveness of the proposed element model. Findings - For the simulation of bus rollover collision, the computational accuracy can be guaranteed, meanwhile, the calculated amount is much smaller than the shell element, and computational efficiency is improved significantly. Originality/value - The proposed four-node membrane element model is used for the simulation of bus rollover collision for the first time. It holds the advantage of high computational efficiency of membrane element, and the computational accuracy is improved as well. In conclusion, it has some practical value in engineering application. © Emerald Group Publishing Limited.

Sesarmid crabs play important roles in mangrove ecosystems as they affect litter carbon pool, nutrient recycling, and retention by their burrowing and foraging activities. The present study reported the effects of decomposition of Aegiceras corniculatum (L.) Blanco leaf and foraging on leaf litter by Parasesarma plicatum (Latreille, 1803) crabs on sediment nutrient concentrations and enzyme activities. Results showed no significant effects on sediment organic carbon (OC) and total nitrogen (TKN) concentrations due to non-leaf foraging activities of P. plicatum crabs. Concentrations of OC, TKN, and humics in sediment were higher in leaf decomposition treatment than in the control, and crab foraging activity accelerated the increase in organic matter, compared to either leaf litter decomposition or crab non-leaf foraging activity. Foraging on mangrove leaf litter by crabs also increased the activities of protease, urease, and invertase which are important in the metabolism of organic carbon and nutrients in sediment. The results further demonstrated that sesarmid crabs play important roles in the carbon and nutrient cycling in mangrove ecosystem, but the crabs had higher accumulation efficiency of leaf nitrogen to sediment than carbon. © 2015, Springer International Publishing Switzerland.
