Nitrogen oxides in industrial flue gas are an important cause of environmental pollution. Non-thermal plasma technology is widely used to remove pollutants in flue gas, based on the oxidation of active particles. In this paper, a dielectric barrier discharge plasma generation system was designed and the oxidation of NO by non-thermal plasma was investigated, focusing on the effects of specific energy density (SED) and oxygen content. The results showed that when SED increased from 960 J/ L to 1920 J/L, the conversion efficiency of NO decreased. At the same time, the decrease of oxygen concentration promoted the conversion of NO. In combination with the oxidation catalyst, NO conversion could be dramatically promoted. A 500 m^3/h pilot-scale device was designed according to the laboratory results. The test was carried out in an industrial silicon submerged arc furnace. The results showed that NO could be completely converted with inlet NO volume fraction of 0~0.005%. The generated NO_2 was adsorbed on the surface of the catalytic material initially and gradually desorbed with the proceeding of the reaction. For inlet NO volume fraction of 0.005%~0.025%, the average outlet NO concentration was 0.001%(volume fraction). The above results confirmed the feasibility of NO conversion employing non-thermal plasma coupled with the catalyst.

Aiming at problems of time-consuming, labor-consuming and limitation in constructing coal mine accident ontology by manual means, an automatic construction method of coal mine accident ontology was proposed. Firstly, taking text of coal mine accident case as data source, BP neural network is used to automatically extract ontology concept. Then, hierarchical relationship and non-hierarchical relationship between ontology concepts are automatically extracted by adopting hierarchical clustering method and association rules method. Finally, ontology concepts, relationship between concepts and examples of coal mine accident are visualized by use of Protégé ontology editor, so as to obtain coal mine accident ontology. The coal mine accident ontology by automatic construction is more comprehensive and can provide strong support for coal mine safety production work.

In order to solve problems of management confusion and linkage lack of coal mine accident knowledge, a coal mine accident ontology based on formal concept analysis was constructed. Firstly, formal contexts are separately constructed based on thesaurus and text set of coal mine, and formal context of heterogeneous resources is obtained through apposition-overlap operation. Then the formal context is converted to concept lattice by use of concept lattice construction tool. Finally, concept, attribute and instance are extracted from the concept lattice to form coal mine accident ontology. The coal mine accident ontology can organize and formally express coal mine accident knowledge, and realize sharing and reuse of coal mine accident knowledge, so as to provide help for coal mine safety warning.

In order to solve problem of insufficient knowledge organization, sharing and reuse of coal mine accident cases, the ontology was introduced into knowledge management of accident cases, and construction and reasoning technology of the ontology-based accident case knowledge base were studied. Based on analysis of the accident case knowledge, accident knowledge representation model and accident case body model were constructed. According to knowledge base model and construction method, the coal mine accident case ontology and rule base were constructed respectively, thus the knowledge base was constructed. Knowledge reasoning application based on the knowledge base of mine accident case was realized with gas accident as an example. The research results show that using the knowledge base of coal mine accident case can achieve the knowledge organization and knowledge automatic inference, and can greatly improve sharing and reuse of the mine accident case knowledge.

Understanding the magnetization reversal and temperature characteristics of synthetic antiferromagnets (SAFs) is helpful for optimizing the magnetic properties. In this study, a series of synthetic antiferromagnets with perpendicular magnetic anisotropy are deposited. The four stable magnetic states of the SAF are determined by the mutual alignment of magnetic moments in the layers and are controlled by both the magnetic interlayer exchange interaction and Zeeman energy. First order reversal curves were employed to investigate magnetization reversal behaviors and distinguish between reversible and irreversible components. An innovative approach to enhancing the antiferromagnetic coupling field and thermal stability involves introducing a Ru insertion and increasing the thickness of the adjacent magnetic layer.

Optimizing the delivery and penetration of nano-sized drugs within liver cancer sites, along with remodeling the tumor microenvironment, is crucial for enhancing the efficacy of chemotherapeutic agents. For this study, a platelet (PLT)-mediated nanodrug delivery system (DASA+ATO@PLT) was developed to improve the effectiveness of chemotherapy. This system delivers nano-sized dasatinib and atovaquone specifically to liver tumor sites and facilitates intra-tumoral permeation upon release. Through JC-1, immunohistochemistry, and DNA damage analyses, the therapeutic effect of DASA+ATO@PLT was assessed. In vitro simulation and intravital imaging were carried out to determine the accumulation of dasatinib and atovaquone in liver tumor sites. The experiment demonstrated the accumulation of dasatinib and atovaquone in tumor sites, followed by deep permeation in the tumor microenvironment with the assistance of PLTs, while simultaneously revealing the ability of DASA+ATO@PLT to remodel the liver cancer microenvironment (overcoming hypoxia) and enhance chemotherapeutic efficacy. This system utilizes the natural tumor recognition ability of PLTs and enhances the chemo-immunotherapeutic effect through targeted delivery of nano-chemotherapeutic drugs to the tumor, resulting in effective accumulation and infiltration. The PLT-mediated nanodrug delivery system serves as a "Trojan horse" to carry therapeutic drugs as cargo and deliver them to target cells, leading to favorable outcomes. [ABSTRACT FROM AUTHOR]

Based on ABAQUS mechanical simulation software and the same bending radius, this paper simulated and an alyzed the strain change trends of metal wires on the different schemes for other key influencing films, such as BPL, PI and TPOC. On the basis of the simulation results, the conclusions are follows: PI thickness thinn ing or TPOC thickness increases can decrease the stra in of the metal wires at bending region. However, the change of BPL thickness has no significant effect. [ABSTRACT FROM AUTHOR]

AMOLED (Active‐matrix organic light‐emitting diode) is a new type of display technology, mainly used in the field of smartphones. Temperature is an important environmental factor for AMOLED displays on their function and performance. Temperature difference can cause changes in the material characteristics of AMOLED displays. It will occur touch failure and inability to respond to users' operations. In order to reduce the adverse effects caused by temperature difference on touch, this paper studied the stability and reliability of different module materials in different temperature environments. The results showed that the module materials had a close relationship with the touch pattern during temperature changed. This paper further explored the pattern design parameter indicators to improve the touch performance of AMOLED through simulation experiments. This study provided a theoretical basis for optimizing the touch function and performance of AMOLED. [ABSTRACT FROM AUTHOR]

With the increasing application and demand of flexible AOLED display modules in the global market, improving the strength performance of display modules has important guiding significance for the development of OLED technology. In this paper, the height of the falling ball is used as the test index of strength performance, and the influence of the composite structure on the strength of the falling ball is studied through the combination of composite structure with different thicknesses and materials. It is found that in the composite structure with the same thickness, using foam instead of PI structure can obtain better ball falling results. The falling result of silica gel material is better than that of foam material, and the overall thickness of silica gel is thinner. [ABSTRACT FROM AUTHOR]

In this study, a novel driving circuit which could extend scan pulse width was proposed and integrated into AMOLED panel. Each scan circuit in gate‐in‐panel region contains four groups of clock signals, while the pixel circuit in active area incorporates dual data line design, in combination with a 1:4 demux circuit in the down border. The measured just noticeable difference values of short‐term and medium‐term image sticking were decreased by more than 25% in LTPS AMOLED modules. This work offers a feasible and effective method to improve the image quality in future flexible AMOLED displays. [ABSTRACT FROM AUTHOR]

Since the concept of Augmented Reality and Virtual Reality was put forward, the experience of using AR/VR devices comparable to the real world has become the motivation and target of the related industries. However, to get better visual immersion, the display module resolution needs to be retina level, i.e., 3000~4000 PPI, or else it will produce a screen door effect, which will degrade the user experience. Since higher PPI means smaller pixel pitch and PDL GAP, the balance between product lifetime and manufacturing cost will be difficult to maintain, which challenges the existing fine‐metal mask version (FMM)‐based AMOLED process steps. To meet the requirements of PPI, we fabricated periodically repeating microstructures to form a grating layer above the light‐emitting area to realize the resolution enhancement, and analyzed the effects of refractive index, thickness, and other parameters.
