2A review on nitrogen transformation and conversion during coal pyrolysis and combustion based on quantum chemical calculation and experimental study显示文摘The emission of NOx during coal combustion contributes to the formation of acid rain and photochemical smog,which would seriously affect the quality of atmospheric environment.Therefore,the decrease of NOx is of great importance for improving the efficient utilization of coal.The present review comprehensively summarized the influence factors and mechanisms of migration and transformation of nitrogen during the coal pyrolysis and combustion based on experimental study and quantum chemical calculation.Firstly,in the process of pyrolysis:the occurrence state and transformation of nitrogen were concluded.The influence of temperature,atmosphere,heating rate and catalyst on formation of NOx precursor and nitrogen migration path at the molecular level were summarized;Secondly,during the process of combustion:the influence of temperature,ambient oxygen concentration,physical structure of coal char,catalyst on heterogeneous oxidation of char(N)were summarized;The effects of char surface properties,catalyst and ambient atmosphere on heterogeneous reduction of NOx were also concluded.Based on the quantum chemical calculation,the reaction path of heterogeneous oxidation of char-N and heterogeneous reduction of NOx were described in detail.Current studies focus more on the generation of HCN and NH3,but in order to reduce the pollution of NOx from the source,it is necessary to further improve the process conditions and the optimal formula of producing more N2 during pyrolysis,as well as clarify the path of the generation of N2.Experiments study and quantum chemistry calculation should be combined to complete the research of directional nitrogen reduction during pyrolysis and denitration during combustion.Tingting Jiao Huiling Fan Shoujun Liu Song Yang Wenguang Du Pengzheng Shi Chao Yang Yeshuang Wang Ju Shangguan 2021Chinese Journal of Chemical Engineering2021,34,7:2

5Ionic liquids in transdermal drug delivery system: Current applications and future perspectives显示文摘The transdermal drug delivery(TDD) shows considerable advantages over other administration pathways.However, conventional enhancing permeation methods face a series of challenges owing to barrier function provided by the skin, of which enhancing abilities either are so strong that it results in toxicity and irritation, or too weak to achieve desirable therapeutical effects. To address these issues, it is an urgent need to develop a novel method to overcome the limitations of current measures. Fortunately, in the preceding decades, ionic liquids(ILs) have been extensively studied and increasingly applied in pharmaceutical drug delivery due to their unique physicochemical and biological properties. What is more, tunability of structure resolves the challenges in processing active pharmaceutical ingredient(API) formulation, such as polymorphism and poor solubility of drugs. Thus, the presence of ILs provides an ample design space for the transdermal drug delivery system(TDDS). This review discusses the shortcomings of conventional enhancing permeation methods and introduces the application of ILs in transdermal delivery from three aspects: i) ILs are applied as enhancers to weaken the barrier function of the stratum corneum(SC). ii) As counterions, ILs are combined with API to modify the physicochemical properties of drugs. iii) ILs assist in the design of transdermal preparation for perfecting formulation. This review comprehensively introduces the major breakthroughs made in the applications of ILs, which can serve as guidance to provide novel ideas for formulation scientists who hit the bottleneck in the development of TDD.Yang Zhang Chao Liu Jiaqi Wang Shoujun Ren Yilin Song Peng Quan Liang Fang 2023Chinese Chemical Letters2023,34,3:1

12Role of iron-based catalysts in reducing NO_(x) emissions from coal combustion显示文摘Nitrogen oxide(NO_(x))pollutants emitted from coal combustion are attracting growing public concern.While the traditional technologies of reducing NO_(x) were mainly focused on terminal treatment,and the research on source treatment is limited.This paper proposes a new coal combustion strategy that significantly reduces NO_(x) emissions during coal combustion.This strategy has two important advantages in reducing NO_(x) emissions.First,by introducing iron-based catalyst at the source,which will catalyze the conversion of coke nitrogen to volatile nitrogen during the pyrolysis process,thereby greatly reducing the coke nitrogen content.The second is de-NO_(x) process by a redox reaction between NO_(x) and reducing agents(coke,HCN,NH_(3),etc.)that occurred during coke combustion.Compared to direct combustion of coal,coke prepared by adding iron-based catalyst has 46.1% reduction in NO_(x) emissions.To determine the effect of iron-based additives on de-NO_(x) performance,demineralized coal(de-coal)was prepared to eliminate the effect of iron-based minerals in coal ash.The effects of iron compounds,additive dosages,and combustion temperatures on de-NO_(x) efficiency are systematically studied.The results revealed that the NO_(x) emission of the coke generated by pyrolysis of de-coal loaded with 3%(mass)Fe_(2)O_(3) decreases to 27.3% at combustion temperature of 900℃.Two main reasons for lower NO_(x) emissions were deduced:(1)During the catalytic coal pyrolysis stage,the nitrogen content in the coke decreases with the release of volatile nitrogen.(2)Part of the NO_(x) emitted during the coke combustion was converted into N_(2) for the catalytic effect of the Fe-based catalysts.It is of great practical value and scientific significance to the comprehensive treatment and the clean utilization process of coal.Yuehua Liu Lili Chen Shoujun Liu Song Yang Ju Shangguan 2023Chinese Journal of Chemical Engineering2023,59,7:0
13Sulfur retention efficiency of clean coke produced by co-pyrolysis of coal with CaCO_(3) to substitute household coal显示文摘Raw coal is used by many suburban and rural households for cooking and heating and results in severe air pollution,especially problematic SO_(2) emissions.A source treatment strategy was proposed to reduce SO_(2) emissions,which used the co-pyrolysis of raw coal with a CaCO3 additive to produce clean coke.The effect of Ca/S molar ratio on the SO_(2) capture efficiency of clean coke was investigated,and the SO_(2) retention efficiency was optimized at a Ca/S molar ratio of 1.5.The sulfur retention mechanism of clean coke was attributed to:(1)CaCO3 decomposition to CaO and partial reaction of CaO with H2S to generate CaS during pyrolysis.(2)Transformation of the remaining sulfur in the clean coke to SO_(2) during combustion,capture by unreacted CaO to form CaSO_(4),and direct oxidation of CaS to CaSO_(4).The feasibility of SO_(2) emission reduction by clean coke in a practical household stove was verified.Shoujun Liu Mingyi Wang Kaixia Zhang Zhongliang Yu Song Yang Ju Shangguan Guoqiang Zhang Wenguang Du Jin Li Yuehua Liu 2021Carbon Resources Conversion2021,4,1:0
14hSnd2/TMEM208 is an HIF-1α-targeted gene and contains a WH2 motif显示文摘Eukaryotic cells have multiple membrane organelles within the cell.One of the cellular challenges is to direct proteins,especially membrane proteins,to the right membrane compartment.Around onethird of the encoded proteins must be targeted to the endoplasmic reticulum(ER)before being trafficked into the right organelles[1].Pinggui Lei Yan Xiao Pei Li Peng Xie Huilin Wang Shoujun Huang Pingping Song Yuanbo Zhao 2020Acta Biochimica et Biophysica Sinica2020,52,3:0
15Heteroatomic Modification of Solid-Waste-Based Mesoporous Carbon for Volatile Organic Compound Adsorption显示文摘Solid-waste-based activated carbon(AC)was utilized as a carbon source to synthesize a series of carbon-based functional material RAC-X(X=P and S,where P and S denote phosphoric and sulfuric acids,respectively).The toluene adsorption capacities of the regeneration AC(RAC)samples can be significantly improved by adopting the heteroatomic modification strategy.RAC-P and RAC-S have the same specific surface area(1156 m^(2)/g)and similar porous structures.However,they have different toluene adsorption capacities,with 316.22 mg/g for RAC-P and 460.12 mg/g for RAC-S,which are 1.6 and 2.4 times greater than that for RAC.The X-ray photoelectron spectroscopy measurements showed that the increase in the amount ofπ–π^(2)chemical bond over the AC surface results in the improvement of the toluene adsorption performance.The density functional theory results showed that the S-containing functional groups loaded near the defect sites of RAC-S promote toluene adsorption.Moreover,reusability tests showed that RAC-S still retains 86%of its adsorption activity after four consecutive adsorption–desorption experiments.This indicates that the heteroatomic modification method affords excellent toluene adsorption performance and recycling practicability,which not only is beneficial for achieving the rational utilization of solid waste resources but also provides a practical method for the efficient elimination of volatile organic compounds.Liu Jun Li Zhi Xu Ke Zhang Xinyang Li Yunpeng Wang Ya Zhang Yongfa Yang Song Liu Shoujun Li Junhua 2023China Petroleum Processing & Petrochemical Technology2023,25,1:0
