| 1 | Preparation and properties of temperature sensitive paint based on Eu(DBM)_3 phen as probe molecule显示文摘Probe molecule Eu(DBM)3 phen is made up of europium oxide(Eu_2 O_3),dibenzoylmethane(DBM) and1,10-phenanthroline(phen). The temperature sensitive paint(TSP) was compounded by the polymerization of the probe molecule, methyl methacrylate(MMA) and the initiator of benzoyl peroxide(BPO).The structure, morphology, luminescence property of probe molecule and the temperature quenching property of the temperature sensitive paint(TSP) were characterized by infrared spectrometer, UV-vis spectrometer, scanning electron microscopy and fluorescence spectrometer respectively. The infrared spectrum and UV-vis spectra show that Eu and DBM form six membered rings, and Eu-O coordinate bonds form. The nanocrystals are in sphere-like morphology with an average size of approximately100 nm. Fluorescence spectra present that the performance of temperature quenching is excellent,what's more, TSP sample has different temperature sensitivity in various temperature scope. Particularly,under excitation of 286 nm, TSP has a highest temperature sensitivity between 50 and 60 ℃, and the strongest fluorescence emission reaches a peak(615 nm). It indicated that probe molecule(Eu(DBM)_3 phen) has strong luminescent intensity and the temperature quenching properties of Eu(DBM)_3 phen/PMMA is good. | Siyu Lu Jing Sun Yuan Wang Wensheng Yu Mengting Sun Siyuan Cui | 2018 | Journal of Rare Earths2018，36，6： | 8 |
| 2 | Crystalline boron nitride nanosheets by sonication-assisted hydrothermal exfoliation显示文摘A simple method to prepare two-dimensional hexagonal boron nitride(h-BN) scalably is essential for practical applications. Despite intense research in this area, high-yield production of two-dimensional h-BN with large size and high crystallinity is still a key challenge. In the present work, we propose a simple exfoliation process for boron nitride nanosheets(BNNSs) with high crystallinity by sonication-assisted hydrothermal method, via the synergistic effect of the high pressure, and cavitation of the sonication. Compared with the method only by sonication, the sonication-assisted hydrothermal method can get the fewer-layer BNNSs with high crystallinity.Meanwhile, it can reach higher yield of nearly 1.68%, as the hydrothermal method with the yield of only 0.12%. The simple sonication-assisted hydrothermal method has potential applications in exfoliating other layered materials, thus opening new ways to produce other layered materials in high yield and high crystallinity. | Zhaobo TIAN Kexin CHEN Siyuan SUN Jie ZHANG Wei CUI Zhipeng XIE Guanghua LIU | 2019 | Journal of Advanced Ceramics2019，8，1： | 7 |

| 8 | Elodexanthones A—J, Isoprenylated Xanthone Derivatives with Diverse Skeletons and Bioactivities from Hypericum elodeoides显示文摘Elodexanthones A—J (1—10), two pairs of rearranged isoprenylated xanthone enantiomers with an unprecedent 6/6/5/6 tetracyclic core (1—2) along with seven new isoprenylated xanthones (3—9) and a pair of phenylpropanoid xanthones (10), were purified and enantio-separated from the whole plant of Hypericum elodeoides. Their structures including absolute configurations were characterized by the comprehensive analysis of NMR, HRESIMS, NMR calculations, and ECD calculations. Through Bayer-Villiger oxidation, Claisen condensation and electrophilic addition, the rearranged skeletons of elodexanthones A—B (1—2) were generated from isoprenylated xanthone precursors. The bioactivities evaluation exhibited that compounds 3, 5, 8—10 showed anti-inflammatory activity with the IC_(50) values in the range of 9.53—34.39 μmol/L, and compounds 3—7, and 9 showed notable α-glucosidase inhibitory activity (IC_(50): 6.02—257.11 μmol/L). | Yanbing Mu Yaqi Li Qiji Li Wenjun Xu Yunpeng Sun Siyuan Wang Letian Cui Lingyi Kong Jun Luo | 2022 | Chinese Journal of Chemistry2022，40，24： | 1 |
| 9 | Evaluation of ecosystem service of straw return to soil in a wheat field of China显示文摘Crop straw is an important natural resource in China because it is rich in nutrients.When returned to fields after harvests,the straw can improve soil quality and the next crop’s yield.Evaluating the economic values of the main ecological services of a farmland ecosystem while implementing the straw return technique can be a more systematic and comprehensive approach to better understand the contribution of straw return to the development of ecological agriculture.Based on the data of a field experiment established in 2010 with varying numbers of years of straw return,four ecological services,i.e.,agricultural product and industrial raw materials,atmospheric regulation and purification,soil nutrient accumulation,and water conservation,were selected to estimate a net ecosystem service value(ESV)of a wheat field’s ecosystem services.Agro-ecosystem service appraisal theories were applied to estimate the economic value of each service.Results showed that straw returning improved the total ESV in the wheat system.Compared to the no straw return treatment,1 year,3 years,5 years or 7 years of straw returning altered the economic value of the agricultural product and industrial raw materials(EVAIM)by-5.93%to 7.84%and improved atmospheric regulation(EVAR)by 13.66%-30.80%,soil nutrient accumulation(EVSNA)by 59.87%-233.31%and water conservation(EVWC)by 2.60%-13.26%.The total ESV of wheat plots with 1-7 years of straw returning was 3.67%-27.41%higher than that with no straw return,and the total ESV increased with the increase in years of straw return.The proportion of EVAIM out of the total ESV in this wheat field system was highest(accounted for 47.09%-55.64%),followed by EVAR and EVWC.The value of EVSNA was the lowest.However,the proportion of EVSNA was higher than that of water conservation after the fifth year of straw return.In general,the adoption of continuous straw returning in a wheat field ecosystem is ecologically valuable.The results can inform the development and implementation of ecological compensation policies involving straw return. | Siyuan Cui Guangqiao Cao Xinkai Zhu | 2021 | International Journal of Agricultural and Biological Engineering2021，14，1： | 0 |
| 10 | Integrin β2 and β3:Two plasmatocyte markers deepen our understanding of the development of plasmatocytes in the silkworm Bombyx mori显示文摘Insect hemocytes play important biological roles at developmental stages,metamorphosis,and innate immunity.As one of the most abundant cell types,plasmatocytes can participate in various innate immune responses,especially in encapsulation and node formation.Here,2 molecular markers of plasmatocytes,consisting of integrinβ2 andβ3,were identified and used to understand the development of plasmatocytes.Plasmatocytes are widely distributed in the hematopoietic system,including circulating hemolymph and hematopoietic organs(HPOs).HPOs constantly release plasmatocytes with high proliferative activity in vitro;removal of HPOs leads to a dramatic reduction in the circulating plasmatocytes,and the remaining plasmatocytes gradually lose their ability to proliferate in vivo.Our results demonstrated that the release of plasmatocytes from HPOs is regulated by insulin-mediated signals and their downstream pathways,including PI3K/Akt and MAPK/Erk signals.The insulin/PI3K/Akt signaling pathway can significantly irritate the hematopoiesis,and its inhibitor LY294002 could inhibit the hemocytes discharged from HPOs.While the insulin/MAPK/Erk signaling pathway plays a negative regulatory role,inhibiting its activity with U0126 can markedly promote the discharge of plasmatocytes from HPOs.Our results indicate that the circulating plasmatocytes are mainly generated and discharged by HPOs.This process is co-regulated by the PI3K/Akt and MAPK/Erk signals in an antagonistic manner to adjust the dynamic balance of the hemocytes.These findings can enhance our understanding of insect hematopoiesis. | Kui Zhang Jingjing Su Xin Hu Xiaomin Yan Siyuan Chen Chongyang Li Guangzhao Pan Hongbo Chang Wenli Tian Muhammad Nadeem Abbas Hongjuan Cui | 2022 | Insect Science2022，29，6： | 0 |
| 11 | Effects of tillage on soil nitrogen and its components from rice-wheat fields in subtropical regions of China显示文摘It is of great significance to explore the effects of different tillage practices on total nitrogen and its components in rice-wheat rotation farmland.The experiment was carried out in Jiangyan County,Jiangsu Province of China,and a total of four treatments were set up:minimum tillage(MT),rotary tillage(RT),conventional tillage(CT),and conventional tillage without straw retention(CT0).The total nitrogen(TN),light fraction nitrogen(LFN),heavy fraction nitrogen(HFN),particulate nitrogen(PN),and mineral-associated nitrogen(MN)in 0-20 cm soil were determined.The results show that MT increased TN concentration by2.26%-27.57%compared with the other treatments in 0-5 cm soil,but it lost this advantage in 5-10 cm and 10-20 cm soil.MT altered the concentration of LFN by 6.03%-95.86%,of HFN by 1.68%-20.75%,of PN by 12.58%-96.83%,and of MN by−1.73%-9.83%as compared to RT,CT,and CT0 in 0-5 cm soil,respectively.With the deepened of soil depth,the concentration of TN,LFN,HFN,PN,and MN decreased quickly in MT,which was lower than that in RT and CT at 10-20 cm soil depth.Straw return increased the concentration of TN and its components in 0-20 cm soil.The concentration of TN was extremely significantly positively correlated with that of LFN,HFN,PN,and MN(p<0.01).The variation of TN was significantly positively correlated with that of LFN,HFN,PN,and MN(p<0.01),and LFN showed the highest sensitivity to tillage practice.In general,minimum tillage combined with straw retention increased the concentration of soil TN and its components in topsoil.LFN was the best indicator to indicate the change in soil total nitrogen affected by tillage practice. | Siyuan Cui Xinkai Zhu Guangqiao Cao | 2022 | International Journal of Agricultural and Biological Engineering2022，15，3： | 0 |
