| 1 | Phosphate removal by a La(OH)_(3) loaded magnetic MAPTAC-based cationic hydrogel:Enhanced surface charge density and Donnan membrane effect显示文摘Cationic hydrogels have received great attention to control eutrophication and recycle phosphate.In this study,a type of La(OH)_(3) loaded magnetic MAPTAC-based cationic hydrogel(La(OH)_(3)@MMCH)was developed as a potential adsorbent for enhanced phosphate removal from aqueous environment.La(OH)_(3)@MMCH exhibited high adsorption capacity of 105.72±5.99 mg P/g,and reached equilibrium within 2 hr.La(OH)_(3)@MMCH could perform effectively in a wide pH range from 3.0 to 9.0 and in the presence of coexisting ions(including SO_(4)^(2-),Cl^(-),NO_(3)^(-),HCO_(3)^(-),SiO_(4)^(4-) and HA).The adsorption-desorption experiment indicated that La(OH)_(3)@MMCH could be easily regenerated by using NaOH-NaCl as the desorption agent,and 73.3%adsorption capacity remained after five cycles.Moreover,La(OH)_(3)@MMCH was employed to treat surface water with phosphate concentration of 1.90 mg/L and showed great removal efficiency of 95.21%.Actually,MMCH showed high surface charge density of 34.38-59.38 meq/kg in the pH range from 3.0 to 11.0 and great swelling ratio of 3014.57%within 24 h,indicating that MMCH could produce the enhanced Donnan membrane effect to pre-permeate phosphate.Furthermore,the bifunctional structure of La(OH)_(3)@MMCH enabled it to capture phosphate through electrostatic attraction and ligand exchange.All the results prove that La(OH)_(3)@MMCH is a promising adsorbent for eutrophication control and phosphate recovery. | Yanqing Zhou Yili Wang Shuoxun Dong Haotian Hao Junyi Li Chenyang Liu Xiaolin Li Yao Tong | 2022 | Journal of Environmental Sciences2022，34，3： | 4 |
| 2 | Nitrate removal from aqueous solutions by magnetic cationic hydrogel:Effect of electrostatic adsorption and mechanism显示文摘Excessive nitrate(NO3-)is among the most problematic surface water and groundwater pollutants.In this study,a type of magnetic cationic hydrogel(MCH)is employed for NO3-adsorption and well characterized herein.Its adsorption capacity is considerably pHdependent and achieves the optimal adsorption(maximum NO3--adsorption capacity is95.88±1.24 mg/g)when the pH level is 5.2-8.8.The fitting result using the homogeneous surface diffusion model indicates that the surface/film diffusion controls the adsorption rate,and NO3-approaches the center of MCH particles within 30 min.The diffusion coefficient(Ds)and external mass transfer coefficient(kF)in the liquid phase are1.15×10-6 cm2/min and 4.5×10-6 cm/min,respectively.The MCH is employed to treat surface water that contains 10 mg/L of NO3-,and it is found that the optimal magnetic separation time is 1.6 min.The high-efficiency mass transfer and magnetic separation of MCH during the adsorption-regeneration process favors its application in surface water treatment.Furthermore,the study of the mechanism involved reveals that both-N+(CH3)3 groups and NO3-are convoluted in adsorption via electrostatic interactions.It is further found that ion exchange between NO3-and chlorine occurs. | Junyi Li Shuoxun Dong Yili Wang Xiaomin Dou Haotian Hao | 2020 | Journal of Environmental Sciences2020，32，5： | 3 |
| 3 | Highly efficient P uptake by Fe3O4 loaded amorphous Zr-La (carbonate) oxides: Electrostatic attraction, inner-sphere complexation and oxygen vacancies acceleration effect显示文摘Bimetallic oxides composites have received an increasing attention as promising adsorbents for aqueous phosphate (P) removal in recent years. In this study, a novel magnetic composite MZLCO was prepared by hybridizing amorphous Zr-La (carbonate) oxides (ZLCO) with nano-FeOthrough a one-pot solvothermal method for efficient phosphate adsorption. Our optimum sample of MZLCO-45 exhibited a high Langmuir maximum adsorption capacity of 96.16 mg P/g and performed well even at low phosphate concentration. The phosphate adsorption kinetics by MZLCO-45 fitted well with the pseudo-second-order model, and the adsorption capacity could reach 79% of the ultimate value within the first 60 min. The phosphate adsorption process was highly p H-dependent, and MZLCO-45 performed well over a wide p H range of 2.0-8.0. Moreover, MZLCO-45 showed a strong selectivity to phosphate in the presence of competing ions (Cl^(-), NO_(3)^(-), SO_(4)^(2-), HCO_(3)^(-), Ca^(2+), and Mg^(2+)) and a good reusability using the eluent of Na OH/Na Cl mixture, then 64% adsorption capacity remained after ten recycles. The initial 2.0 mg P/L in municipal wastewater and surface water could be efficiently reduced to below 0.1mg P/L by 0.07 g/L MZLCO-45, and the phosphate removal efficiencies were 95.7% and 96.21%, respectively. Phosphate adsorption mechanisms by MZLCO-45 could be attributed to electrostatic attraction and the inner-sphere complexation via ligand exchange forming Zr/La-O-P, -OH and CO_(3)^(2-)groups on MZLCO-45 surface played important roles in the ligand exchange process. The existence of oxygen vacancies could accelerate the phosphate absorption rate of the MZLCO-45 composites. | Chenyang Liu Yili Wang Xiaolin Li Junyi Li Shuoxun Dong Haotian Hao Yao Tong Yanqing Zhou | 2022 | Journal of Environmental Sciences2022，34，10： | 2 |
| 4 | Highly efficient and thermal stable guanidinium-based two-dimensional perovskite solar cells via partial substitution with hydrophobic ammonium显示文摘Layered two-dimensional(2D)perovskite solar cells(PVSCs)with a chemical formula of C(NH2)3(CH3NH3)3Pb3I10(n=3)have been fabricated through additive engineering,wherein stoichiometrically equivalent guanidinium(GA+)and methylammonium(MA+)serve as spacer cations.The crystallinity of the perovskite films is dramatically enhanced with proper amount of methylammonium thiocyanate(MASCN)added into the precursor solution.In addition,we substitute a small amount of MA+with hydrophobic phenylethylammonium(PEA+),which can passivate trap states of the perovskite films.As a result,the open circuit voltage increases to 1.1 V and the best power conversion efficiency(PCE)of 10.12%is yielded.Furthermore,superior thermal stability and balanced moisture stability of the PEA-substituted GA-based PVSCs are demonstrated,compared to the popular 3D MAPbI3and 2D PEA-based PVSCs.They retain approximately 80%of the original PCE after 30 d at 20%relative humidity(RH),and 50%of the original PCE after 3200 min at 85°C without any encapsulation.This work suggests a new route to achieve both heat and humidity stable PVSCs by simply mixing different spacer cations. | Yingzhu Zhang Jiehuan Chen Xiaomei Lian Weitao Yang Jun Li Shuoxun Tian Gang Wu Hongzheng Chen | 2019 | Science China Chemistry2019，62，7： | 2 |
| 5 | Effects of trace ytterbium addition on microstructure,mechanical and thermal properties of hypoeutectic Al-5Ni alloy显示文摘Over the past decade,the cast aluminum alloys with excellent mechanical and conductivity properties have emerged as potential materials for thermal management.However,the traditional Al-Si based alloys are difficult to make significant breakthrough in conductivity performance.The hypoeutectic Al-5Ni alloy also possesses sound castability and is expected to be applied in thermal management applications.In this study,the effects of ytterbium(Yb element) at 0-0.5 wt% on the microstructures as well as the electrical/thermal conductivity and mechanical properties of the Al-5Ni alloy were systematically investigated.The experimental results indicate that the addition of Yb at a relatively low amount not only reduces the secondary dendrite arm spacing of the α-Al grains,but also modifies the morphology and distribution of eutectic boundary phase.Moreover,it is found that the dosage of Yb at 0.3 wt% in the Al-5Ni alloy can simultaneously improve the yield strength,ultimate tensile strength and electrical/thermal conductivity.The strengthening and toughening of the Al-5Ni alloy are mainly attributed to the decrease of secondary dendrite arm spacing and the improvement of eutectic phases.The transmission electron microscopy/selected area electron diffraction(TEM/SAED) analysis indicates that the ytterbium in Al-5Ni alloy will form Al_(3)Yb phase,which mainly agglomerates in the Al_(3)Ni phase region.This phase is helpful to decrease the solubility of impurity elements(e.g.,Fe and Si) in the α-Al matrix,which is beneficial to electrical/thermal conductivity.The value of this study lays foundation for manufacturing Al-Ni alloys with high thermal conductivity and acceptable mechanical properties. | Kang Wang Shaodong Hu Yanglin Zhong Shuoxun Jin Zirong Zhou Zhiyu Wang Jiongcai Chen Bingbing Wan Wenfang Li | 2022 | Journal of Rare Earths2022，40，8： | 2 |

| 8 | Beyond the Green Revolution: Improving crop productivity and sustainability by modulating plant growth-metabolic coordination显示文摘Rice is one of the most important staple food for over half the world's population.New evidence from the Food and Agriculture Organization shows that the number of hungry people in the world is growing,reaching more than 690 million in 2020.It is an urgent task to increase crop production to feed the people suffering from chronic hunger in the world.The Green Revolution of the 1960s boosted cereal yields through widespread adoption of semi-dwarf varieties and extensive use of inorganic fertilizers(Khush,2001).Today,the most productive Green Revolution varieties(GRVs)of rice and wheat in the world retain semi-dwarf phenotypes,which have several advantages over tall traditional varieties:(1)they have a lower center of gravity of the plant body,which decreases the risk of lodging and allows farmers to apply excessive fertilizers to obtain high yield;(2)they have an increased harvest index,which enables plants to allocate more energy and resources to seed production。 | Qian Liu Kun Wu Yunzhe Wu Wenzhen Song Shuoxun Wang Xiangdong Fu | 2022 | Molecular Plant2022，15，4： | 1 |
| 9 | Pyramiding of the dep1-1 and NAL1NJ6 alleles achieves sustainable improvements in nitrogen-use efficiency and grain yield in japonica rice breeding显示文摘Rice is one of the most important cereal crops in the world, and a substantial increase in grain yield is necessary for food security. However, high yields of semidwarf modern rice varieties are heavily dependent on the application of mineral nitrogenous fertilizer (Tilman et al., 2002;Sun et al., 2014). Nitrogen (N)-insensitive sponses associated with reduced N-use efficiency (NUE) is a major characteristic of the green revolution varieties (GRVs), in which the growth-inhibiting protein SLENDER RICE1 (SLR1) accumulates (Li et al., 2018). Unfortunately, increasing the level of N fertilizer use to reach the full yield potential of GRVs is subject to diminishing returns, quite apart from its deleterious effect on the environments (Rahn et al., 2009;Liu et al., 2015). Therefore, there is an urgent need to develop new rice GRVs that increase NUE while maintaining their high yields. Recently, several genes (e.g., DEP1, OsNRTl.lB, OsNRT2.3b, ARE1 and GRF4) responsible for improved NUE have been identified in rice (Sun et al.. 2014;Hu et al., 2015;Fan et al., 2016;Wang et al., 2018;Li et al., 2018). More importantly, boosting the activity of the transcription factor GRF4 overcomes the ability of SLR1 to prevent the GRF4-GIF1 interaction, which in turn promotes the coordinated expression of the genes involved in N assimilation and carbon fixation and consequently enhances the NUE of rice GRVs, thereby improving our ability to grow crops sustainably (Li et al., 2018). However, current understanding of the genetic basis for improving NUE remains at the level of identification of a number of quantitative trait loci (QTLs), without any understanding of the nature of the gene products. | Xiaopeng Xu Kun Wu Ruineng Xu Jianping Yu Jing Wang Ying Zhao Yun Wang Wenzhen Song Shuoxun Wang Zhi Gao Yongjia Zhong Xinxin Li Hong Liao Xiangdong Fu | 2019 | Journal of Genetics and Genomics2019，46，6： | 1 |
| 10 | Modulating the C-terminus of DEP1 synergistically enhances grain quality and yield in rice显示文摘Grain shape is a key breeding target that influences both grain yield and appearance quality in rice. Breeding for long-slender grains is an effective strategy to improve grain quality (Jain et al., 2004;Wang et al., 2012, 2015a). In the past two decades, several quantitative trait loci (QTLs) responsible for grain size and shape have been identified, including GS3 (Fan et al., 2006), GS5 (Li et al., 2011). | Haixiang Huang Yafeng Ye Wenzhen Song Qi Li Ruixi Han Chenchen Wu Shuoxun Wang Jianping Yu Xueying Liu Xiangdong Fu Qian Liu Kun Wu | 2022 | Journal of Genetics and Genomics2022，49，5： | 1 |
