Nickle and Cobalt Spinel Catalyzing Wet Air Oxidation of Refractory Pollutants under Mild Condition
Authors: Jing Qi , Li Huan 
Published: July 2019

Abstract
Refractory organic pollutants are critical issues in water or wastewater treatemnt, and catalytic wet air oxidation (CWAO) is a common method. To improve the efficiency and decrease the reaction conditions, a type of NiCo2O4 (NCO) spinel with urchin-like hollow strucutres was synthesized and used in CWAO of organics at low temperature and atmosphere pressure. Both scanning electron microscopy and X-ray photoelectron spectra were used to characterize NCO. The 3-D hierarchical architectures, solid state redox couple M2+/M3+ (M represents Ni or Co), and plenty of surface oxygen species were proved. Furthermore, the reaction path of CWAO with NCO as the catalyst was concluded, i.e. consecutive adsorption, surface oxidation, and re-oxidation of reduced NCO by O2. NCO showed excellent catalytic performance in CWAO of refractory organics, such as alkaline lignin and bisphenol A. The removal rates of total organic carbon exceeded 80% within 3 h. These findings promise a convenient and economical way for the treatment of refractory organics in water or wastewater.

Published: July 2019

Abstract
To explore the effects of exogenous silicon on the adsorption characteristics of arsenic in paddy field soils, the impacts of silicon on adsorption kinetic characteristics of arsenic in the acidic paddy field soil in northern China were studied under neutralizing alkaline of Sodium Silicate and balancing Na+ of different treatments. The results indicated that silicon reduced the adsorption amount of arsenic in soils and shortened the adsorption equilibrium time. The adsorption process of arsenic in the soil could be well described by Elovich equation. Silicon increased the equation parameters α and β values, which indicated that exogenous silicon could accelerate the initial arsenic adsorption rate in soils and reduce the reaction rate during the absorption process.

Published: July 2019

Abstract
The brittleness of shale gas reservoir determines the effect of fracturing reconstruction, which is of great significance for improving shale productivity. The study of shale brittleness evaluation can provide basic data for fracturing design. The mineral composition characteristics of shale gas reservoir in the early Cambrian Qiongzhusi formation of Huize area, Eastern Yunnan Province are reported in this paper, and the brittleness is evaluated according to the proportion of brittle minerals in total minerals. The results show that the mineral composition of the reservoir is complex. After comparing the brittleness index calculated by different formulas, it is considered that the minerals with high young’s modulus and low poisson’s ratio should be considered as brittle minerals, which is conducive to the universality of the brittleness index formula and the objectivity of reservoir brittleness evaluation. Shale gas reservoir of Qiongzhusi formation is obviously divided into two sections: the layers of 1 to 7 with a large brittleness index (77.60% on average) on the lower part are beneficial to reservoir fracturing reconstruction, while the layers of 8 to 14 with a small brittleness index (37.78% on average) on the upper part are not conducive to reservoir fracturing reconstruction. This study is conducive to guiding further exploration and development of shale gas in the research area.

Authors: Xie Yongdong , Yang Luxi , He Zhongqun 
Published: July 2019

Abstract
A pot experiment was conducted to study the effects of arbuscular mycorrhizal fungi (AMF) Glomus mosseae-2 on photosynthetic characteristics of tomato under different concentrations of NaCl (0.3%, 0.6% and 1%) stress. The results showed that salt stress reduced the net photosynthetic rate and light saturation point of tomato. Although AMF did not increase the light saturation point of tomato, it could increase the net photosynthetic rate, stomatal conductance, apparent quantum yield and CO2 carboxylation efficiency of the leaves, and improve chloroplast photophosphorylation activity, which was conducive to maintaining the ability of chloroplast to absorb light energy and improving tomato light energy conversion efficiency and CO2 utilization efficiency. When the inoculated and non-inoculated plants were treated with 0.3-0.6% NaCl, the photosynthesis decline was mainly affected by stomatal limitation, after 28 days of treatment with 1% NaCl, the decline of photosynthesis was mainly affected by non-stomatal factors, and inoculation with AMF could improve the photosynthesis of tomato under salt stress.

Optimized inhibition on Microcystis aeruginosa by combined use of UV-C irradiation and hydrogen peroxide
Authors: Zheng Jie , Zhou Tingru , Tao Yi 
Published: July 2019

Abstract
In order to optimize H2O2/UV-C treatments on suppressing cyanobacterium, apoptotic-like and necrotic growth suppression were investigated respectively. Results showed that apoptotic-like algal inhibition exhibited a positive correlation with UV-C dose in the study period. Dosing strategy for apoptotic-like inhibition is that an environmentally friendly H2O2 dose should be determined with priority. Then, UV-C dose should be mediated to achieve a specific objective for algal inhibition. For necrotic inhibition, increasing H2O2 dose exhibited weak enhancement in growth inhibition while existence of UV-C irradiation could negatively influence following cell lysis after treatments. Hence, dosing strategy for necrotic inhibition is that a moderate H2O2 dose without UV-C irradiation should be efficient in achieving a specific objective for algal inhibition. For mechanism of death switch, given a specific UV-C dose, corresponding high H2O2 dose could cause a deficiency of ATP and switch from apoptosis-like to necrosis.

Published: July 2019

Abstract
From the current global energy consumption distribution, traditional fossil fuels still occupy a dominant position, and their share will remain high for some time to come. However, limited non-renewable traditional resources cannot always be used by humans. When they are finally consumed, the consumption of traditional fossil fuels such as oil, natural gas, coal, etc. will generate a lot of greenhouse gases, and the massive emissions of CO2 will cause a series of unfavorable chain reactions. Photocatalytic reduction of CO2 as a hydrocarbon fuel not only reduces the CO2 content in the atmosphere, but also solves the environmental problems brought about by the greenhouse effect, and can provide energy fuel with considerable economic effects. The research progress of photocatalytic reduction of CO2 is reviewed. Some common TiO2-based photocatalytic materials are introduced, and the characteristics of various materials are compared. Finally, the research on TiO2-based photocatalytic materials is prospected

Published: July 2019

Abstract
MIL-101 is a typical metal-organic framework. Mil-101, like the other metal-organic frameworks (MOFs) is a material with high porosity, large surface area, adjustable micro-pore size, and easy functional structure. Contrary to the most MOFs, Mil-101 has a high hydrothermal stability. All of the characteristics collectively make MIL-101 a good candidate for a catalyst support. In this paper, the synthesis methods of MIL-101 materials have been reviewed. It is pointed out that the hydrothermal synthesis method has many problems such as complicated process, many organic waste liquid and low yield. The room temperature fast synthesis method has the potential to provide industrialized production of MIL-101 with its unique advantages.

Abstract
The rapid development of logistics and electronics industry has produced a large number of express packaging garbage, which is gradually destroying the environment and wasting resources, the implementation of express packaging recycling has become the key, but consumer participation in express packaging recycling intention is not strong. Based on the theory of planned behavior, social exchange, perceived trust and situational factors, this paper constructs a model of influencing factors of consumers’ willingness to participate in express packaging recycling, and makes an empirical analysis using structural equation model. The results show that recycling attitudes, perceived behavior control, perceived benefits, convenience and policy propaganda have a significant positive impact on consumers’ willingness to participate in express packaging recycling. Subjective norms, perceived trust and perceived benefits have a certain impact on recycling attitudes.

Authors: Chang Honglei , Qu Mingyue , Cheng Mengying , Liu Jian 
Published: July 2019

Abstract
Chloride transport under wetting and drying environment is very complicated. A lot of research has reported maximum phenomena in chloride profiles under such environment. Considering the fact that most specimens in which chloride maximum was detected before either had inhomogeneous surface (might be influenced by skin effect) or were exposed to natural environment (might be influenced by rain washing), this study aims to reveal chloride distribution under mere wetting and drying condition in cement-based materials. The chloride distribution results in the surface layer of specimens with different water to binder ratio (W/B) detected by silver nitrate titration method (SNT), ion chromatography method (IC)and electric probe micro analysis (EPMA) present a fact that: maximum phenomena occur in all specimens under four wetting-drying regimes, no matter in paste or mortar, in free or total chloride, and whether with slag (SL) and fly ash (FA) or not. It suggests that mere wetting and drying action can incur chloride maximum phenomenon without the attendance of skin effect and rain washing, though sometimes confined by the accuracy of testing method, the position of maximum phenomenon can not be presented.

Published: July 2019

Abstract
A crucial issue in today’s counterterrorism environment is how to assess critical infrastructure damage and develop a more appropriate design rapidly against intentional attacks, since it has become unacceptable to ignore the high impact of disruptions caused by these attacks. Degraded states vulnerability methodology (DSVM) is used to explore the vulnerability analysis and design method of critical infrastructures. After the terrorist attack, the damage status of the components at all levels of the target is quickly determined, and the probability of component level damage is simulated. Using this method to judge the functional damage condition and improve the planning and design under multi-hit. Respond quickly to the damage effect of each hit, and put forward multi-hit’s degraded states transition tables and state-effect tables. It provides the basis for rapid assessment, planning and design of critical infrastructure in modern local wars where terrorists are more intensive and frequent.
Above-threshold ionization of hydrogen atoms in a two-color laser field
Authors: Guo Zhijian 
Published: July 2019

Abstract
By using the method of electron wave packet interference, we investigate the above-threshold ionization (ATI) of hydrogen atoms in a linearly polarized two-color laser pulse (λ
1 = 800 nm and λ
2 = 400 nm). Firstly, using the strong field approximation (SFA) with the time window function, we obtain the intracycle interference and intercycle interference patterns of hydrogen atoms in a 10 fs laser pulse, and it is found that the general characteristics of two-dimensional photoelectron momentum spectrum are formed by the interplay of the intracycle interference and intercycle interference, and the side rings in two-dimensional photoelectron momentum spectra originate from intercycle interference. Subsequently, we calculate the two-dimensional photoelectron momentum spectra of hydrogen atoms by SFA in full pulse. When the relative phase ϕ = 0, the intracycle interference and intercycle interference fringes in two-dimensional momentum spectrum are symmetrical, and when the relative phase is ϕ=0.5π, the intracycle interference fringes in the two-dimensional momentum spectrum are obviously asymmetrical. The results show that ionization is vitally dependent on relative phase of two laser pulses in two-color laser filed.
