Authors: Li Zhen , Wang Nan , Zhao Pengxiang , Zhou Xichao , Wang Yongli , Zhang Danyang 
Published: November 2020

Abstract
Aiming at the wind abandonment problem of CCHP “determining electricity by heat”, this paper proposes an optimal scheduling method that takes into account the coordination of source and charge of the integrated energy system of wind power. Introduce a ground source heat pump on the source side, use wind power for heating, and decouple the CCHP’s “constant heat” operation constraints; use the price demand response on the charge side to assist wind power grid integration; finally, consider the coordination of source and charge to establish an integrated energy system. The upper layer adopts the electricity price demand response to guide users to respond to changes in wind power output. The lower layer considers the role of ground source heat pumps and determines the optimal output of each unit with the minimum total system cost in the dispatch cycle. The full text is solved using Matlab software. The calculation example shows that this method effectively improves the wind power consumption capacity of the system, reduces the system operating cost, and has good social and economic benefits.

Published: November 2020

Abstract
In order to reduce the deposition of dust on the surface of the fin of the air cooler, the influencing factors of dust deposition were studied. Firstly, the airflow along the working face is observed, which provides variable reference and data support for the wing dust deposition experiment. Then, the dust collecting test platform was built to simulate the dust collecting on the air cooler fins. Finally, the key factors that affect the dust deposition on the fins are studied by controlling the variables. The results show that the condensate water plays an important role in the dust deposition of the air cooler fins in high temperature and high humidity environment. When the amount of condensed water is less, the condensed water is adhered to the surface of the fin, which has the effect of adhesion to the particles, thus speeding up the deposition of dust on the surface of the fin. When the amount of condensed water is large, the condensed water moves downward under the action of gravity and carries away the dust attached to the fin surface, thus slowing down or even reducing the deposition of dust on the fin surface.

Published: November 2020

Abstract
Electricity is an indispensable material basis for economic development. It is necessary to study the relationship between different electricity consumption and economic growth. Based on the quarterly data of China’s electricity consumption and economic development from 2011 to 2018, the long-term equilibrium relationship between variables is analyzed from a causal perspective, the short-term fluctuations between variables are analyzed from a relative effectiveness perspective, and electricity consumption indicators for reflecting economic development are identified. The results show that there is a long-term equilibrium relationship between secondary industry electricity consumption, industrial electricity consumption and GDP. There is a constant or decreasing returns to scale between electricity consumption and GDP, and the demand for electricity consumption still needs to be met urgently.

Published: November 2020

Abstract
Based on big data analysis, for the actual operating data, the method of dividing non-uniform working conditions was studied to obtain typical data of different working conditions. The traditional sliding pressure curve is only a shortcoming of the single value function of the load. Convolution neural network is applied to build a nonlinear model of load, main steam temperature, reheated steam temperature, ambient temperature and main steam pressure. And then, the real-time optimized value of the main steam pressure is obtained. After verification, the model is proved to be satisfactory in both precision and regularity. Finally, the main steam pressure optimization model is applied to the actual 300MW thermal power unit, and closed-loop control is performed. The results prove that the application of real-time main steam pressure optimization can effectively reduce the energy consumption of the unit, and have higher energy saving potential at different ambient temperatures.

Effects of Plants and Plant Fermentation Broth on the Removal and Characteristics of Dissolved Organic Matter in Self-Supplying Carbon Source Constructed Wetlands Treating Secondary Effluent
Authors: Yu Tingting , Guo Wenrui , Zhang Mingxiao , Wen Yue 
Published: November 2020

Abstract
In this study, four constructed wetlands (CWs) were developed. The effects of plants and plant fermentation broth on the removal and characteristics of dissolved organic matter (DOM) were evaluated. As the ratio of added COD to influent nitrate (CODAdd/NO3-N ratio) increased from 0 to 4, the DOC removal rate increased from 0.48 to 5.41 g m−3 d−1 in the unplanted microcosms, and from 0.75 to 5.73 g m−3 d−1 in the planted ones. The presence of plants could increase the DOC removal rate from 0.48–5.41 g m−3 d−1 to 0.75–5.73 g m−3 d−1. This indicated that both the addition of plant fermentation broth and planting could greatly improve the DOC removal during the CW treatment. Moreover, adding plant fermentation broth introduced highly aromatic compounds into the microcosms, and thus increased the UV254 and SUVA values of the effluent. The plants could lower the effluent UV254 value through improving the removal of aromatic compounds, but it increased the SUVA value by increasing the proportion of aromatic compounds in total DOMs.

Authors: Wang M Y , Wu Q 
Published: November 2020

Abstract
Based on the calculation of density functional theory, the adsorption and dissociation of NO on Pd (111) surface were systematically studied. The results show that the most stable adsorption mode of NO was at fcc site with N-terminal downward, followed by hcp site and top site; Bader charge and charge density difference analysis show that there was obvious charge transfer between NO and Pd(111) surface; the analysis of density of states further indicates that there was obvious chemical interaction between them; the dissociation barrier of NO on Pd(111) surface is 2.45eV, which indicates that NO is easy to poison Pd metal surface. Finally, the two dissociation pathways of NO adsorbed on fcc site indicate that NO is very difficult to dissociate on Pd (111) surface.
Slope instability judgment criteria in FEM based on strength reduction method
Authors: Peng Xiaogang , Li Jia , Li Youzhi , Jiang Jian 
Published: November 2020

Abstract
The correct judgment of the instability state affects the reduction coefficient obtained by the strength reduction finite element method, and then affects the calculation result of the safety factor. Taking the Griffiths slope as an example, the Abaqus software was used to calculate the instability criteria using three types of criteria: non convergence of numerical iteration, sudden change in displacement of characteristic parts, generalized plastic strain or equivalent plastic strain penetration. The results show that there is a corresponding relationship between whether the numerical calculation is converged and whether the slope is unstable. When the calculation is terminated due to non-convergence, the strength reduction coefficient does not change much, and the setting of the finite element convergence condition has little effect on the result. Therefore, it is recommended to use finite element calculation for convergence as a basis for determining slope instability.

Authors: Chen Nuo 
Published: November 2020

Abstract
Fluoroquinolone antibiotics (FQs) have a good bactericidal effect on a variety of bacteria, and are widely used in the treatment of various diseases. Due to the low residue and high stability in foods and water environment, it is difficult to detect FQs. Magnetic molecular imprinted technology (MIT) is specifically used for detection and identification, and magnetic molecular imprinted polymers (MIPs) are obtained by combining modified magnetic materials with polymers with specific molecular recognition cavities, which not only improves the ability to select and recognize specific template analogs, but also enables rapid separation. This review summarizes the research progress of MIPs with natural magnetic materials, magnetic nanomaterials and magnetic molecular sieve materials as carriers according to the cost, points out the advantages and current problems of each magnetic material, and describes the current status and development prospects of magnetic MIPs.

Published: November 2020

Abstract
Taking automotive glass regulator (glass regulator for short) as investigative object, fatigue life of glass regulator in top dead center locked-rotor condition is analyzed by adopting the combined simulation of ABAQUS and FE-SAFE. Firstly, calculation criterion of fatigue life of glass regulator and the combined simulation steps of analyzing fatigue life of glass regulator are investigated. Afterwards, HYPERMESH is used to generate mesh of glass regulator and ABAQUS is used to finite element analyze glass regulator. Then, stress condition is obtained. Finally, stress condition, material fatigue property, loading spectrum are imported into FE-SAFE for analyzing fatigue life, and fatigue life nephograms are gained. Fatigue life nephograms suggest that fatigue life of plate curved part on slider, flanging on guide rail, the part near the mounting hole of guide pulley are short, on which risk of fatigue failure exists. This method provides theoretical basis for design of fatigue life of glass regulator.

Published: November 2020

AbstractA slowly-released polycarboxylate superplasticizer with high slump retention was obtained at room temperature by using Isoamyl enol polyoxyethylene ether (TPEG), 2-hydroxyethyl acrylate (HEA), acrylic acid(AA), and acrylamide (AM) as the main raw material, and using hydrogen peroxide (H2O2) as initiator and mercaptoacetic acid as the chain transfer agent. The effect of initiator dosage, chain transfer agent dosage and acrylamide dosage on the performance of the product were investigated. The results showed that under the optimum polymerization conditions of the slowly-released polycarboxylate superplasticizer with high slump retention, the dosage of initiator, chain transfer agent and acrylamide was 0.3%, 0.25% and 0.9% based on the mass of the macromonomer, respectively. The molecular weight distribution under the optimum synthesis conditions was determined by gel permeation chromatography (GPC) and the structure of the polymer was characterized by spectroscopy (FTIR). Compared with commercial similar produces and other synthesized slowly-released polycarboxylate superplasticizer, the test results showed that the developed superplasticizer had an excellent slump retention ability.
Recent advances in the production of γ-valerolactone with liquid hydrogen source
Authors: Zhou Yangyuan , Wang Li , Guo Pengfei , Yao Guodong 
Published: November 2020

Abstract
Gamma(γ)-valerolactone (GVL) which can be produced from carbohydrate biomass has been regarded as one of the most promising platform chemicals because it can be converted to liquid alkenes adapted for transportation fuels. In the producing process, GVL was synthesized via hydrogenation of levulinic acid, which was obtained from acidic hydrolysis of carbohydrate biomass. Generally, gaseous hydrogen was employed as hydrogen source in the hydrogenation reaction. However, highly pure and high-pressure gaseous hydrogen faces high risk of hydrogen storage, transportation and operation. Moreover, due to the need for activating the gaseous hydrogen, noble metal catalysts were commonly used, limited the large-scale application. Some liquids, such as formic acid, alcohol and water, can act as hydrogen donor under cerain conditions. Liquid hydrogen source possesses safe and high efficiency advantages in the hydrogenation process. This paper highlights the recent progress in the production of GVL with liquid hydrogen source.

Abstract
NaN3, as a kind of rich-nitrogen energetic material, engaged in the synthesis of hierarchical transition metal (Co/Ni) organic framework materials (MOFs) through a facile hydrothermal reaction, during which aqueous N3
− function groups being as an unique ligand in preparation of novel coordination polymer with the existence of Co2+ (or Ni2+) salts and dicyandiamide. The obtained compounds (Co-eMOF, Ni-eMOF, NiCo-eMOF) were characterized by structure and composition analysis, specific surface area, thermogravimetric analysis (TGA) and crystal X-ray diffraction. The prepared products regardless of the metal cautions (Co, Ni, or coexist Co and Ni), perform a well three-dimensions (3D) nanostructures with spherical shaped monoliths, known as organic framework materials. The as-prepared products with developed porosity demonstrate a high surface area in range of 80∼130 m2/g. XRD patterns for these three examples show similar lattice crystalline, which to an extent matches well with the simulated MOF-74 materials, suggesting profound formation of oriented crystal growth. XPS reveals the compounds all equipped with high nitrogen content (54∼60 at%), which is largely hinging on the contribution from N3
− function groups, suggesting the superiority of NaN3 serving as the rich nitrogen precursor. Accounting for extensive application, we will apply this as-prepared (Co/Ni) MOF materials as one kind of nitrogen-rich precursor and conduct them for further calcination treatment for preparation of graphite-based transition metal carbides (TMC), and it is highly anticipated to achieve efficient activity towards electrocatalysis in our follow-up actions.

Abstract
Autonomous ships rely on sensory data to perceive objects of interest in their environment. Deep Learning based object detection in the image domain commonly used to solve this issue. The robustness of such approaches in non-ideal conditions is, however, still to be proven. In this work state of the art methods are applied on the RetinaNet architecture attempting to create a more robust object detection network given noisy input data. The GroupSort activation function and Spectral Normalization is used and the results are compared to the standard RetinaNet network. Our findings show that these modifications perform better and ensure robustness under moderate noise levels, than the standard RetinaNet network.

Published: November 2020

Abstract
Standardised test manoeuvres are used to identify the manoeuvrability of a vessel. Currently, most of these tests are unsatisfactory to properly judge the manoeuvring capabilities of an inland vessel which sails in different environments than the seagoing ships for which these tests were initially designed. Moreover, inland vessels tend to have non-conventional propulsion systems and configurations which further decreases the adequacy of these standardised tests. Therefore, this study investigates the inland-applicability of these existing standardised test manoeuvres. In addition, this study suggests three new manoeuvres: (i) the Counter Thrust Test, (ii) the Sine Angle Test, and (iii) the Simultaneous Zigzag Test. In order to validate the suitability of these tests, an autonomous inland cargo vessel performed two of these suggested manoeuvres, (i) and (ii), and one existing manoeuvre, named the Crabbing test. The data of these experiments show fruitful insights in the wide range of manoeuvring capabilities of the examined inland vessel, which the standardised tests would not have uncovered.
