“…Jiao et al successfully synthesized boehmite nanoparticles of different sizes and shapes using the CADH method. Zhang et al and Yang et al incorporated Mg and Ni, respectively, into mesoporous alumina by the CADH method to synthesize binary oxides, which displayed higher CO 2 adsorption capacities as compared with other MgO-based adsorbents and excellent electrochemical cyclability. Ullah et al applied the CADH method to prepare zinc–nickel–aluminum ternary oxide composites, which exhibited improved reactive adsorption desulfurization performance.…”

A highly dispersed nickel catalyst supported on alumina with an NiO loading of 40 wt % has been prepared from Ni(NO3)2·6H2O and NaAlO2 as precursors through a novel cation–anion double-hydrolysis strategy. The product has been tested for its efficacy in CO methanation. The preparation process can be considered as a time-saving and green synthetic technique that does not require the use of a basic precipitation agent. The resulting Ni/Al2O3 catalyst shows a high dispersion of NiO with small particle size (<5 nm), in spite of the high metal loading. Various promoters, namely Zr, Fe, and Ce, were further added to regulate the catalytic properties of the Ni/Al2O3 catalyst, and 40Ni-5Zr/Al2O3 showed the optimal CO methanation activity. The improved catalytic performance could be mainly due to the high degree of Ni dispersion and the abundance of oxygen vacancies, which enhanced the adsorption and dissociation of CO.

“…Zhao [6] think when pH value was less than 6.4, ANAMMOX would not occur. Yang's [7] research showed that when the pH value was 8.3, the ANAMMOX sludge activity was the largest, but when pH value is greater than 8.3, the activity declined. He [8] found in the ANAMMOX process with a 8.1 pH value, ammonia nitrogen removal rate is significantly higher than 7.6.…”

The biological treatment process of landfill leachate in Beijing Liulitun landfill is a multistage A/O technology, in which a large amount of ANAMMOX (Anaerobic ammonia oxidation, ANAMMOX) bacteria were found in the sludge. There are several factors impacting the activity of ANAMMOX bacteria, including pH value, temperature and HRT which in this process are suitable for the survival of ANAMMOX bacteria. Especially, low dissolved oxygen is an essential factor as the provider of electron donor for nitrite formation. Although the high concentrations of organic matter, ammonia nitrogen and nitrite will inhibit the occurrence of ANAMMOX, ANAMMOX bacteria can self-detoxification by forming a low-poison habitat by consuming ammonia and nitrite as well as organic matter by heterotrophic ANAMMOX bacteria.

“…The demand for wearable power source has given an enormous impetus to flexible energy harvesting and storage devices. − For the flexible energy storage devices like supercapacitor or lithium ion battery, metal oxide or carbon materials were sandwiched layer-by-layer between flat metal or carbon foil, or wrapped over conductive wires. − Emerging wire-type devices have attracted extensive attention in recent years. They could be enrolled, twisted, or woven into various shapes, to facilitate the dressing. − A key issue obstructing the way to the commercial application is their relatively low energy density and power density.…”

In the search for clothlike wearable energy-storage devices with both high energy density and high power density, metal fibers surrounded by micro metal dendrites, as current collectors, are either rooted inside a thick layer of carbon particles or wrapped with flowerlike nano NiO in a similar manner to the root or stem system of natural plants, to form dendritic cablelike negative or positive electrodes. These dendritic cable electrodes could be further combined or woven into flexible solid-type supercapacitive garland or fabric, together with cotton wires. Benefiting from the ultra large interface of the metal dendrites current collector, it can be charged up to 1.8 V, and give an energy density of 0.1408 mWh cm and a power density of 3.01 mW cm, which is capable of directly starting a small electric car with a short and flexible piece of supercapacitor.
