Research on electron and positron spectrum in the high-energy region based on the gluon condensation model
Authors: Wu Jin-tao , Feng Ming-jun , Ruan Jian-hong 
Published: October 2023

Abstract
Electron (positron), proton and nuclei can be accelerated to very high energy by local supernova remnants (SNR). The famous excesses of electron and proton (nuclei) potentially come from such kind of local sources. Recently, the DAMPE experiment measured the electron spectrum (including both electrons and positrons) of cosmic rays with high-accuracy. It provides an opportunity to further explore the excess of electrons. According to the gluon condensation (GC) theory, once GC occurs, huge number of gluons condense at a critical momentum, and the production spectra of electron and proton showing typical GC characteristics. There are exact correlations between the electron and proton spectrum from a same GC process. It is possible to interpret the power-law break of cosmic rays in view of GC phenomenon, and predict one from another based on the relations between electron and proton spectrum. In this work, we point out the potential existence of a second excess in the electron spectrum, the characteristics of this excess is derived from experimental data of proton. We hope that the future DAMPE experiments will confirm the existence of this second excess and support the result of GC model.
Holographic Schwinger effect in spinning black hole backgrounds*
Authors: Cai 蔡 Yi-Ze 镒泽 , Zhang 张 Zi-Qiang 自强 
Published: October 2023

Abstract
We perform a potential analysis for the holographic Schwinger effect in spinning Myers-Perry black holes. We compute the potential between the produced pair by evaluating the classical action of a string attached on a probe D3-brane at an intermediate position in the AdS bulk. We find that increasing the angular momentum reduces the potential barrier, thus enhancing the Schwinger effect, consistent with previous findings obtained via the local Lorentz transformation. In particular, these effects are more visible for the particle pair lying in the transversal plane compared with that along the longitudinal orientation. In addition, we discuss how the Schwinger effect changes with the shear viscosity to entropy density ratio at strong coupling under the influence of angular momentum.
The influence of temperature on the properties of anti - ice materials
Authors: Gan Gan 
Published: October 2023

Abstract
The results of experimental research and practical application of anti-icing surface fully show that its performance is greatly affected by temperature. The anti-icing measures of anti-icing surface can be divided into three stages: before icing, during icing and after icing. In these three stages, the influence brought by temperature change is respectively reflected in: the adhesion of water droplets to the surface, the time it takes for ice nucleation, the adhesion of ice to the surface. Surface anti-ice technology has important application in aviation and aerospace field. The surface temperature of aircraft will change greatly when the aircraft is sailing at different altitudes and passing through different climatic environments. If ice accumulates in some parts of the aircraft, even if it is small, it may lead to a decrease in the climbing force of the aircraft and an increase in flight resistance, thus leading to the deterioration of aerodynamic performance such as the maneuverability and stability of the aircraft. Studying the influence of these temperature changes on the anti-icing performance of aircraft surface can avoid the air disaster caused by surface icing. Starting from these three stages, this paper analyzes the influence of temperature on material surface and the liquid itself successively in these three stages, so as to further explore the influence of temperature on ice suppression performance.
Use of fibre reinforced polymer (FRP) in new construction and in strengthening of existing structures
Authors: Li Renjie 
Published: October 2023

Abstract
Concrete is the primary construction material for most building projects today owing to its versatility, moldability and superior strength in compression. Concrete however is an inherently brittle material with quite poor tensile strength and has very low resistance to cracks and their propagation throughout the medium. In this research paper, a thorough compilation of previous work on the development of FRPs, their performance under various conditions through traditional structural loading techniques such as 4-point loading and their implementation is provided. Fibre reinforced polymers (FRP) allow alterations in concrete’s structural behaviour under tensile loading as well as expansions during exposures to extreme temperatures and routine shrinkage cracks through addition of small fibres that act as anchors preventing the widening of cracks as well as behaving in a similar fashion to the conventional steel reinforcement. FRP not only comes from small hair like fibres but also in the form of wraps which provide confinement on beams and columns increasing the compressive strength of the element as well as reducing the tensile loads, similar to how prestressing tendons alter the behaviour of prestressed concrete.

Authors: Lyu Peishan 
Published: October 2023

Abstract
Humans widely utilize solar energy as a green and sustainable resource. Furthermore, semiconductor photocatalysis can use sunlight for reaction without other additional energy, so it has received wide attention. Bi2MoO6 shows excellent potential in visible photocatalysis due to its narrow band gap, high stability, and non-toxicity. This review focuses on the modification methods of Bi2MoO6 photocatalysts. By adjusting the treatment of Bi2MoO6 with different modifications, the photogenerated electron-hole complexation can be retarded, and its specific surface area increases, thus enhancing its photocatalytic performance. This article begins with describing the current state of photocatalysts, the mechanism of the photocatalytic process, as well as important bottlenecks and affecting factors. Then, three techniques for making Bi2MoO6 photocatalysts are provided, and their attributes are compared in various ways. Four approaches for enhancing the photocatalytic performance of the material are outlined and addressed. Then, the organic pollutant degradation performance of Bi2MoO6 photocatalysts generated by various modification techniques is studied. Finally, the existing issues with Bi2MoO6 photocatalysts and ways to improve them are explored.

Abstract
SARS-CoV-2 has been threatening the human’s health which caused numerous infections and deaths since its outbreak in 2020. Various techniques for its detection have been researched and published for early diagnosis of SARS-CoV-2 to reduce infections. Currently, most methods target on the RNA using the PCR. It is reliable to the laboratory and professional staffs, but is inconvenient and untouchable for citizens to do the rapid test these days. In this review, the recent progress of design for SARS-CoV-2 detection using the electrochemical immunosensors, a kind of biosensors, has been introduced. Unlike the other skills, it targets on the antigen of the virus and the diagnostic results can be obtained through the current or potential changes caused by the redox reaction of the immunocomplex. In addition, this review would focus on the selection of the bio-receptor, the assay format and the modification of the electrode. This paper will hopefully shed light on pathogen detection with electrochemical immunosensors.

Authors: Fan Yan 
Published: October 2023

Abstract
With the continuous in-depth research of spintronics, the manufacture of high-performance magnetic random access memory devices and electronic devices that are more energy-efficient and generate less heat has received extensive attention. The traditional ferromagnet TbMnO3 is basically Tc at room temperature, which seriously limits its application. Since the discovery of diluted magnetic semiconductor materials at room temperature, such as AlNTiO2, ZnO, SnO2, etc., they have received increasing attention. Although these dopants can form ferromagnetism above-room temperature, the ferromagnetic mechanism and ferromagnetic properties are different. In this regard, we reviewed the current progress in the research on above room temperature dilute magnetic semiconductor materials; discussed the ferromagnetic mechanism of dilute magnetic semiconductors; summarized the problems and challenges, and advantages and disadvantages of different kinds of dilute magnetic semiconductor materials used in new memory devices; and prospected the application potential of spintronic devices.
Biofuels for transportation
Authors: Zhang Felix 
Published: October 2023

Abstract
Biofuels for transportation is an essential factor of significant measures to increase fuel security, combat climate change, and promote rural development. The rising amount of greenhouse pollution brought on by the use of fossil fuels is now widely recognized. The energy crisis results from the growing disparity between the energy needs of the industrialized world and the finite amount of energy from fossil fuels. Among energy consumers, the transportation sector is frequently cited as one of the primary pollutant sources. For instance, the second-most polluting industry in the USA in 2014 was the transportation sector. Transportation ranked fourth in pollution-producing industries in 2014, contributing 14% of all pollutants worldwide. Due to the rise in emissions of CO2, which caused global warming, the significant impact of large vehicles on polluted air as well as other gases or airborne contaminants has become a significant issue. Acid rain and climate change are both projected to be significantly reduced by reducing the quantity of pollution produced by the transportation industry. Fossil fuels now provide approximately 98% of the energy used in the transport industry. In this regard, it has been suggested that one way to combat the enormous environmental impact of using fossil fuels is to consume and use environmentally friendly alternative fuels like biofuels, fuel cells, and solar power. Researchers and decision-makers are interested in biofuel as one of the possible gasoline substitutes that can lower the level of pollution emissions.

Authors: Yin Kaixin 
Published: October 2023

Abstract
Facilitating the development of cities in coastal areas is an economic strategy from a global perspective. Currently it can be seen that large developed cities in many countries are distributed along the coast. However, in recent years, with the influence of climate change, sea level rise, cyclone changes and land subsidence, the frequency of compound storm floods has been increasing. More academics begin work on compound storm flooding. It can be found that the development of the flood model has experienced a process from ordinary static simulation to one-Dimensional-three-Dimensional coupled model. At present, there are mainly hurricane model and hydrodynamic model to study the composite storm flood. Through current storm flood models, it is known that the intensity and frequency of storm floods will increase under current climate change conditions. At the same time, this paper also looks forward to the models, and proposes an improvement plan to increase the application scope of the model.
Coagulation technologies for separation of microplastics in water: current status
Authors: Pu Kundi 
Published: October 2023

Abstract
The pollution of the microplastics in the water environment has already been a threat to the whole ecosystem. Numerous MPs are detected in the ocean and the treated wastewater from the wastewater treatment plant. Due to its small particle size, MPs are proven to penetrate through animal cells and cause even fatal harm to the aminal itself. These reports discuss how well the coagulation behaves in MPs’ separation from the water environment and what factors could affect the MPs’ separation efficiency using coagulation. Recent studies about the coagulation used in MPs separation from water has been reviewed, and the MPs removal efficiency for conventional coagulation and electro-coagulation is determined to be 8.28% to 98.2% and 8.24% to 99.4% respectively. The result and conclusion of this study hopefully provide references for people who study the MPs in water and its management strategy in the future.

Analyzing the current state and future development of carbon capture, utilization and storage (CCUS) strategies and technologies in China
Authors: Wang He 
Published: October 2023

Abstract
Carbon capture, utilization, and storage (hereafter as CCUS) encompass the procedures of capturing carbon dioxide before it is emitted into the atmosphere, transporting it via pipelines or vehicles and finally utilizing it or storing it in a secure manner. CCUS is vital in transitioning the world into more sustainable and low carbon energy production since it serves as a temporary “band-aid” in reducing the impacts of humanity’s high dependence on fossil fuels. The Chinese government has recently committed itself to reach carbon neutrality by 2060 and CCUS technologies will be a critical cornerstone in reaching this substantial goal. Up to 60% of China’s energy supply in 2019 derived from coal, thus an effective CCUS strategy integrated with the 1,110 operational Chinese coal power plants could be decisive in reaching their carbon neutrality goal. This research paper will analyze the most effective best available technologies (BATs) in terms of cost efficiency and practicality, providing a comprehensive report on the optimal steps for China to take in order to reach its carbon neutral goals through CCUS.

Published: October 2023

Abstract
Uniform droplets production technology, which include continue ink jet and drop on demand technology, has been widely used in many fields, such as electronic packaging and inkjet printing. The continue ink jet and drop on demand all need a periodic driving force to produce uniform droplets. However, there is a lack of research on the transformation process from drop on demand to continue ink jet technology. In this paper, the Ansys Fluent software platform was used to research the transformation process. The transformation process could be realized by increase the jet velocity of liquid-column and the frequency of the pulse wave at the maximum value of the pulse wave of 0.5m/s.

Authors: Bao Jia-Bao , Kun-Zhang  
Published: October 2023

Abstract
The exhaust manifold is connected to the engine cylinder block and concentrates the exhaust from each cylinder into the exhaust manifold with divergent piping. Research on how the stability and efficiency of the exhaust manifold affects the aftertreatment system of an automobile is actively conducted. Therefore, this article studies to derive the most suitable model for the design of the exhaust manifold of an automobile by analyzing and comparing its pressure distribution, flow distribution, and temperature distribution according to the different shapes of the exhaust manifold. The thermal characteristics were studied and analyzed using FLUENT in ANSYS 2019R3. The results of the analysis are as follows, based on the results of the comparative analysis of the pressure distribution, case 1 shows a low-pressure difference of 200 Pa. In the results of the analysis of the flow rate, the flow rate fluctuations are confirmed in cases 3, 2 and 1 in sequence. Furthermore, when the temperature distribution was analyzed comparatively, it was found that the shape of the car exhaust manifold did not have an effect on the temperature. Therefore, as a result of these findings, the Case 1 model was inferred to be the most suitable model for the design of the exhaust manifold shape of the automobile.
Numerical Study of the Effect of Imaginary Circle Diameter on the Combustion in a Corner-tangentially-fired Boiler
Authors: Sheng Ranran 
Published: October 2023

Abstract
The key factor affecting the combustion and operation of corner tangentially fired boilers (CTFBs) is the diameter of the imaginary circle. In this paper, the temperature and reducing gas distribution in a 350 MW supercritical CTFB were studied numerically, and the influence of imaginary circle diameter on combustion characteristics was analyzed. The results show that: 1) When the diameters of the imaginary circles of the primary and secondary air are decreased, there will be a delay in combustion. This is not profit to the steady-state burning of coal powder. In addition, the temperature near the water wall decreases, and the volume fraction of CO and H2S decreases on the rear side of the main combustion area, but increases significantly on the side of the fire. 2) By reducing only the diameter of the imaginary circle of primary air, the ignition distance of pulverized coal in the lower burner can be advanced, which is profit to improving combustion stability at low loads. Besides, the temperature, CO and H2S volume fraction near the water wall all decrease. 3) When the imaginary circle diameters of primary and secondary air in the upper part of the furnace are reduced, the temperature, volume fraction of CO and H2S in the adjacent layer near the water wall are increased.

Authors: Wei Xinjian , Yang Wuyang , Zhang Xiangyang , Li Shuping , Li Haishan , Xu Xin , Liu Shuren , Fu Zhanbao 
Published: October 2023

Abstract
During the process of seismic acquisition, due to the undulation of the ground surface and workers operation errors, it is easy to cause the actual position of the shot to deviate from the original design, which has a negative impact on the NMO accuracy and data stacking in the later stage, and even causes construction accidents such as continuous generation of abandoned shots in the field seismic acquisition site. The existing algorithms for the location deviation and correction of shots were generally lack of subjectivity, low automation, low efficiency and low accuracy. After studying the nearest-offset trace properties, this paper proposes a real-time detection of shot position deviation and correction method, which by comparing the consistency of the nearest-offset trace determined by the theoretical first break and actual one, judges the shot position deviation and corrects it. The actual application of this method shows that it fully meets the needs of real-time monitoring the quality of seismic data under the current efficient seismic acquisition conditions, and achieves good application results.

Abstract
In this paper, discrete element simulation software EDEM and Tavares crushing model were used to carry out numerical simulation research on the motion characteristics and crushing characteristics of materials in the MZ100 vibration mill during the grinding process. The influence of material characteristics, shape characteristics and filling rate of grinding media, vibration frequency, and amplitude of vibration mill on the efficiency and effect of vibration mill was analyzed. The factors affecting the distribution characteristics of the rotary center of mass and the low-energy region of the grinding medium in the grinding cavity are discussed. The extreme inflection point of the crushing efficiency of the grinding material in the grinding cavity with respect to the increase of the excitation frequency is obtained. In order to improve the grinding efficiency and reduce the low energy zone, the optimum process parameters of eccentric vibration grinding were discussed, which provided theoretical guidance for the efficient crushing of grinding materials.
Molecular Dynamics Simulation of the Effect of Zr, B, C, W, Ti, Hf, Nb, and Ta Elements on the K3AlF6-Na3AlF6-AlF3 Molten Salt System
Authors: Zhou Yuhan , Zhang Zhihao , Zeng Jing , He Hanbing 
Published: October 2023

Abstract
The criticality of the physicochemical properties of the K3AlF6-Na3AlF6-AlF3 molten salt system to electrolytic aluminum production is a topic of great interest. In this study, molecular dynamics simulations were conducted to investigate the impact of Zr, B, C, W, Ti, Hf, Nb, and Ta on various properties including the radial distribution function, coordination number, viscosity, and conductivity of the 23.4K3AlF6-54.6Na3AlF6-22AlF3 molten salt electrolyte under conditions of 1173 K and standard atmospheric pressure. Significant and noteworthy discoveries were yielded by the simulations. A decrease in the coordination between Al-F and conductivity was brought about by the inclusion of B2-. Likewise, higher Zr4+ content resulted in a decrease in the coordination number between Al-F and viscosity. The impact of carbon was insignificant, while the presence of tungsten reduced the coordination number between Al-F. On the other hand, titanium, hafnium, niobium, and tantalum facilitated the decomposition of Al-F ligands, leading to an increased coordination between Al-F and the ions in the electrolyte. These findings provide valuable insights for future investigations on inert anodes containing Zr, B, Ti, Hf, Nb, and Ta. By understanding the effects of these elements on the physicochemical properties of the molten salt electrolyte, this work lays a solid foundation for further research in the field.
