Xueqi Lin KOREA INSTITUTE FOR HUMANITIES AND SOCIAL SCIENCES 2023 Journal of Arts and Cultural Studies(ACS) Vol.2 No.1

Jin Yong, a prominent Chinese author, is often associated with the culture of "tea" in China. His martial arts novels are rich in tea culture, including tea ware, tea leaves, tea ceremonies, and tea etiquette, which are all significant Chinese cultural symbols closely related to traditional Chinese cultural concepts and Jin Yong's spiritual connotations. Methods: This paper employs semiotic theory to decode the tea culture symbols in Tian Long Ba Bu(Demi Gods and Semi Devils). Results: Demonstrating how these symbols not only create a Jianghu (lawless world) that combines killing and etiquette but also construct emotional concepts of various ethnic groups. Furthermore, these symbols convey Jin Yong's cultural spirit of "tea and the Dao, tea and emotions, tea and people." Conclusions: As the novel has been internationally recognized, these tea cultural symbols have become an iconic representation of the world's perception of China

Alpha-ketoglutaric acid (a-KG) is a crucial intermediate with broad application prospects. However, thedownstream separation of a-KG from fermentation broth with low concentration and complex componentshas become the bottleneck of large-scale production. In this study, a-KG was separated from theactual fermentation broth by aqueous two-phase system (ATPS) and crystallization. The optimal ATPScomposed of acetone/(NH4)2SO4 was selected by studying the phase diagram and a-KG distributionbehavior in different organic solvents and salts/sugars. Under the optimized conditions, the purity ofa-KG products from crude fermentation broth reached 98.08%, and the one-pass extraction efficiencywas 90.52%. The removal of cell debris and soluble proteins increased with the increase of acetone and(NH4)2SO4 concentrations, with the removal ratios reaching up to 99.44% and 86.54%. In addition,92.56% of the glucose was distributed in the aqueous phase. Although the a-KG fermentation broth ismore complex than the whole-cell biotransformation, impurities in the crude fermentation broth couldbe efficiently removed and a higher a-KG distribution coefficient was obtained. Meanwhile, the recovered(NH4)2SO4 could be reused for fermentation medium. This strategy provides an economical and effectivemethod combined with upstream biosynthesis to recover a-KG and other bioproducts from crude fermentationbroth.

Characterization of tunnel oxide passivated contact with n-type poly-Si on ptype c-Si wafer substrate

Xueqi Guo,Yuheng Zeng,Zhi Zhang,Yuqing Huang,Mingdun Liao,Qing Yang,Zhixue Wang,Minyong Du,Denggao Guan,Baojie Yan,Jichun Ye 한국물리학회 2019 Current Applied Physics Vol.19 No.7

The junction properties of tunnel silicon oxide (SiOx) passivated contact (TOPCon) with n-type poly-Si on p-type c-Si wafer are characterized using current-voltage (J-V) and capacitance-voltage (C-V) measurements. The dark J-V curves show a standard diode characteristic with a turn-on voltage of ∼0.63 V, indicating a p-n junction is formed. While the C-V curve displays an irregular shape with features of 1) a slow C increase with the decrease of the magnitude of reverse bias voltage, being used to estimate the built-in potential (Vbi), 2) a significant increase at a given positive bias voltage, corresponding to the geometric capacitance crossing the ultrathin SiOx, and 3) a sharp decrease to negative values, resulting from the charge tunneling through the SiOx layer. The C of depleting layer deviates from the normal linear curve in the 1/C2-V plot, which is caused by the diffusion of P dopants from the n-type poly-Si into the p-type c-Si wafer as confirmed by the electrochemical capacitance-voltage measurements. However, the 1/C2+γ-V plots with γ > 0 leads to linear curves with a proper γ and the Vbi can still be estimated. We find that the Vbi is the range of 0.75–0.85 V, increases with the increase of the doping ratio during the poly-Si fabrication process, and correlates with the passivation quality as measured by the reverse saturated current and implied open circuit voltage extracted from transient photoconductivity decay.

Mouxin Wu,Xueqi Jiang,Jihua Chen,Hongge Yan,Weijun Xia,Bin Su,Yifu Deng 대한금속·재료학회 2024 METALS AND MATERIALS International Vol.30 No.1

The thermal conductivity of magnesium alloys is increasingly required for fast heat dissipation in the automotive and electronicfields. However, the methods for mechanical property improvement such as grain refinement and alloying tend to deterioratetheir thermal conductivity. In this work, a novel low-alloy Mg–2Ga–0.6Ca–0.6Ce alloy exhibits a surprisingly goodcombination of high strength and high thermal conductivity compared with the other samples. The wrought alloys are of smallgrain sizes (< 2 μm), have high yield strength (> 272 MPa) and exhibit excellent thermal conductivity (> 143 W·m−1·K−1). The as-extruded alloy exhibits excellent yield strength (272 MPa) and high thermal conductivity (144.6 W·m−1·K−1) atroom temperature. After 30% rolling, the yield strength is further increased to 283 MPa, and the thermal conductivity isslightly reduced to 143.2 W·m−1·K−1. The effects of Ca and Ce addition on mechanical properties and thermal conductivityare analyzed from dislocation density, dynamic recrystallization fraction (fDRX), average grain size (dDRX) and texturecharacteristics. The higher yield strength can be attributed to the combination of grain boundary strengthening, dislocationstrengthening and second phase strengthening. Moreover, the addition of Ca and Ce can obviously reduce solute Ga atomsin α-Mg, which is the key to high thermal conductivity. Therefore, adding two alloying elements, Ca and Ce, significantlyimproves both tensile properties and thermal conductivity.

Purpose: Coronary flow reserve (CFR) in the non-infarcted myocardium is often impairedfollowing acute myocardial infarction (AMI). However, the clinical significanceof CFR in the non-infarcted myocardium is not fully understood. The objective of the present study was to assess whether a relationship exists between CFR and left ventricular remodeling following AMI. Materials and Methods: We enrolled 18 consecutive patients undergoing coronary intervention. Heart function was analyzed using real-time myocardial contrast echocardiography at one week and six months aftercoronary angioplasty. Ten subjects were enrolled as the control group and were examinedusing the same method at the same time to assess CFR. Cardiac troponin I (cTnI) levels were routinely analyzed to estimate peak concentration. Results: CFR was 1.55±0.11 in the infarcted zone and 2.05±0.31 in the remote zone (p<0.01) at one week following AMI. According to CFR values in the remote zone, all patients were divided into two groups: Group I (CFR <2.05) and Group II (CFR >2.05). The levels of cTnI were higher in Group I compared to Group II on admission (36.40 vs. 21.38, p<0.05). Furthermore, left ventricular end diastolic volume was higher in Group I compared to Group II at six months following coronary angioplasty. Conclusion: Microvasculardysfunction is commonly observed in the remote myocardium. The CFR value accurately predicts adverse ventricular remodeling following AMI.

Jie Wu,Xueqi Wang,Zhaomin Yao,Qingqing Wu,Wei Fang,Zegeng Li,Dianlei Wang 대한약학회 2019 Archives of Pharmacal Research Vol.42 No.11

In the present study, the roles of AITC in upregulatingthe MRP1 expression and its relationship with theactivation of the Notch1 signaling pathway were investigatedby combining the in vivo and in vitro experiments. AITCwas administered to the COPD model rats and normal ratsto explore the association between Notch1 and MRP1. Thehuman bronchial epithelial cells were treated with DAPT,the Notch1 signaling pathway inhibitor, to verify the effectof Notch1 on the expression of AITC-induced MRP1. Comparedwith the control group, the expressions of Notch1,Hes1 (the target gene of Notch1) and MRP1 in the lung tissueof the COPD model group were significantly inhibited. In contrast to the COPD model group, the expressions ofMRP1, Hes1 and Notch1 dramatically up-regulated followingthe treatment with Low/High doses of AITC. The expressionof MRP1 in the 16 HBE cells was down-regulated bythe inhibition of Notch in a DAPT concentration-dependentmanner. Additionally, the AITC-induced up-regulation ofthe MRP1 expression was markedly impaired following the inhibition of Notch1. The above results indicated that thepulmonary function and the expression of MRP1 in COPDrats could be improved by AITC, which was partly dependenton the Notch1 signaling pathway. Therefore, targetingthe Notch signaling pathway may present as an effectivetherapeutic strategy for COPD treatment.

Depositional and diagenetic controls on the reservoir quality of Upper Triassic Chang-7 tight oil sandstones, southwestern Ordos basin, China

Ai Wang,Dakang Zhong,Haihua Zhu,Lele Guo,Zhuopei Li,Yangjinfeng Jiang,Xueqi Yang,Rui Xie,Xiaowei Zheng 한국지질과학협의회 2019 Geosciences Journal Vol.23 No.3

The seventh oil layer of the Upper Triassic Yanchang Formation (Chang-7) tight oil sandstone reservoirs is a major exploration target. A significant amount of hydrocarbons has been discovered in these reservoirs in the southwestern Ordos basin in China. The Chang-7 tight sandstones are characterised as tight with low porosity, low permeability, and strong heterogeneity. This study investigates the sedimentary facies, diagenesis, and their impact on the reservoir quality of the Chang-7 tight oil sandstones. The sandstones were deposited in a deltaic-lacustrine depositional system. Three major depositional facies are identified consisting of delta front fed by braided rivers and meandering rivers, and slump turbidite fans. The depositional environment exerts a key control on reservoir quality. The distinct low-energy sedimentary environment produced fine to very fine-grained sandstones with high matrix and mica contents, characterised by low initial porosity and permeability. Diagenesis mainly comprised mechanical compaction and cementation by quartz, carbonate minerals and various clay minerals. The reservoir properties of the Chang-7 sandstones are generally poor, with porosity of 1.4–20.7% (average porosity 8.6%) and permeability of 0.001–116.7 mD (average 0.2 mD), which are attributed to significant compaction and cementation. Mechanical compaction was more important than cementation for reducing porosity, whereas secondary dissolution porosity was significant for the Chang-7 tight oil sandstones due to closer proximity to the underlying Chang-73 source rocks.

Diagentic features of illite in Upper Triassic Chang-7 tight oil sandstones, Ordos Basin

Ai Wang,Dakang Zhong,Haihua Zhu,Lele Guo,Yangjinfeng Jiang,Xueqi Yang,Rui Xie 한국지질과학협의회 2019 Geosciences Journal Vol.23 No.2

The Upper Triassic Chang-7 tight oil sandstones are the main tight clastic reservoirs in the Ordos Basin, central China. Illite is one of the most important cements affecting porosity and permeability of the tight oil sandstones, and this study focuses on different types of illitization and its relative formation time. The Chang-7 tight sandstones are mainly fine-grained lithic arkose and feldspar lithic sandstones, rich in mica and illite (hydrous mica). They are formed in distal delta front to semi-deep and deep lake facies, mainly deposited in a low energy environment. Porosity and permeability are very low (average porosity 8.58% and permeability 0.20 mD). The illite has many morphological characteristics and is multiphase, incorporating six types of illitization: hydrous mica, mica, and smectite illitization at the eodiagenetic stage, and kaolinite and K-feldspar illitization, and neoformation illite particles, at the mesodiagenetic stage. These different types of illitization are mainly controlled by sedimentary environment and provenance. Quartz overgrowth and diagenetic illites appear to be locally mutually exclusive, competing for detrital grain surfaces, but neoformation illite particles appear to form on the quartz overgrowth. The systematic study of Upper Triassic Chang-7 tight oil sandstones carried out here, enhances our understanding of illitization and the diagenetic model of the Ordos Basin, and contributes to reducing the exploration risk of continental tight sandstone reservoirs.
