| 2 | Realization of warm white light emitting in single phase Gd(P_(x)V_(1−x))O_(4):y at% Sm^(3+),1 at% Bi^(3+) phosphor显示文摘A series of single phase,warm white light emitting phosphors,Gd(P_(x)V_(1−x))O_(4):y at%Sm^(3+),with 1 at%Bi^(3+) doping concentration were synthesized by high temperature solid state method in this work.The experimental results indicate broadband cyan emission of Bi^(3+)and characteristic orange-red emission of Sm^(3+)can be effectively tuned by changing the ratios of PO^(3−)_(4)/VO^(3−)_(4) in Gd(P_(x)V_(1−x))O_(4):1 at%Sm^(3+),1 at%Bi^(3+),and the energy transfer process among VO^(3−)_(4),Sm^(3+),Bi^(3+) also can be adjusted.Based on this,warm white light emitting can be realized by further optimizing the doping concentration of Sm^(3+) in the phosphors.At 423 K,the PL intensity of Gd(P_(0.7)V_(0.3))O_(4):2 at%Sm^(3+),1 at%Bi^(3+) remains~84.3%of the initial value at 293 K,while the measured quantum efficiency is 67.8%.EL spectrum analysis results of the fabricated white light emitting diode(wLED)based on a 310 nm UV-chip and Gd(P_(0.7)V_(0.3))O4:2 at%Sm^(3+),1 at%Bi^(3+)phosphors imply low correlated color temperature(3132 K)and appropriate color-rending index(R_(a)=82.7).These results demonstrate that Gd(P_(0.7)V_(0.3))O4:2 at%Sm^(3+),1 at%Bi^(3+)is a good candidate for manufacturing UV-activated warm white light emitting diodes. | Chao Dou Yanzhen Yin Fei Zheng Zhen Wang Shijia Sun Chen Hu Yang Che Bing Teng Degao Zhong | 2022 | Journal of Rare Earths2022，40，4： | 2 |
| 3 | Computational studies of the structure and cation-anion interactions in 1-ethyl-3-methylimidazolium lactate ionic liquid显示文摘Quantum chemical calculations of the structures and cation-anion interaction of 1-ethyl-3-methylimidazolium lactate ([Emim][LAC]) ion pair at the B3LYP/6-31++G** theoretical level were performed. The relevant geometrical characteristics, energy properties, intermolecular H-bonds (H-bonds), and calculated IR vibrations with respect to isolated ions were systematically discussed. The natural bond orbital (NBO) and atoms in molecule (AIM) analyses were also employed to understand the nature of the interactions between cation and anion. The five most stable geometries were verified by analyzing the relative energies and interaction energies. It was found that the most of the C-H···O intermolecular H-bonds interactions in five stable conformers have some covalent character in nature. The elongation and red shift in IR spectrum of C-H bonds which involve in H-bonds is proved by electron transfers from the lone pairs of the carbonyl O atom of [LAC] to the C-H antibonding orbital of the [Emim]+. The interaction modes are more favorable when the carbonyl O atoms of [LAC] interact with the C2-H of the imidazolium ring and the C-H of the ethyl group through the formation of triple H-bonds. | HE HongYan ZHENG YanZhen CHEN Hui ZHANG XiaoChun YAO XiaoQian ZHANG SuoJiang | 2012 | Science China Chemistry2012，55，8： | 2 |

| 11 | Rigid Dysprosium(Ⅲ)Single-Molecule Magnets Exhibit Preserved Superparamagnetism in Solution显示文摘Molecules with long preserved magnetic moments are perceived as the smallest units for storing bytes,which could bring a new revolution for information technology.However,the rational design of such molecules remains challenging.Here two rigid adamantanol ligand based dysprosium(III)complexes([Dy(1-AdO)_(2)(py)_(5)]BPh_(4)-1 and[Dy(2-AdO)_(2)(py)_(5)]BPh_(4)-2)with pentagonal-bipyramidal coordination geometry and local D5h symmetry were successfully prepared,which display excellent single-molecule magnet(SMM)behavior(U_(eff)≈1835 K,T_(B)_(ZFC)≈24 K,T_(B)^(100s)≈17 K and T_(B)^(H)=23 K for 1;U_(eff)≈1756 K,T_(B)^(ZFC)≈20 K,T_(B)^(100s)≈16 K and T_(B)^(H)=23 K for 2)due to the much weakened vibration in low energy regimes.Remarkably,the large energy barriers and high blocking temperatures for these two complexes in solid states are well preserved in solution.This is never observed in previous studies of SMMs,indicating that the adamantanol is rigid and can be introduced to make the composed molecules stable enough to maintain the solid state magnetic property in solution. | Xiali Ding Qiancheng Luo Yuanqi Zhai Xufeng Zhang Yi Lv Xinliang Zhang Chao Ke Chao Wu Yanzhen Zheng | 2022 | Chinese Journal of Chemistry2022，40，5： | 1 |
| 12 | Fusion of Internal Similarity to Improve the Accuracy of Recommendation Algorithm显示文摘Collaborative filtering algorithms(CF)and mass diffusion(MD)algorithms have been successfully applied to recommender systems for years and can solve the problem of information overload.However,both algorithms suffer from data sparsity,and both tend to recommend popular products,which have poor diversity and are not suitable for real life.In this paper,we propose a user internal similarity-based recommendation algorithm(UISRC).UISRC first calculates the item-item similarity matrix and calculates the average similarity between items purchased by each user as the user’s internal similarity.The internal similarity of users is combined to modify the recommendation score to make score predictions and suggestions.Simulation experiments on RYM and Last.FM datasets,the results show that UISRC can obtain better recommendation accuracy and a variety of recommendations than traditional CF and MD algorithms. | Zejun Yang Denghui Xia Jin Liu Chao Zheng Yanzhen Qu Yadang Chen Chengjun Zhang | 2021 | Journal on Internet of Things2021，3，2： | 0 |
| 13 | Modern pollen assemblages and their relationships with vegetation and climate on the northern slopes of the Tianshan Mountains, Xinjiang, China显示文摘The reconstruction of paleovegetation and paleoclimate requires an understanding of the relationships between surface pollen assemblages and modern vegetation and climate.Here,we analyzed the characteristics of surface pollen assemblages across different vegetation zones in the Tianshan Mountains.Using surface pollen analysis and vegetation sample surveys at 75 sites on the northern slopes of the Tianshan Mountains,we determined the correlation between the percentage of dominant pollen types and the corresponding vegetation cover.Redundancy analysis was used to investigate the relationships between surface pollen assemblages and environmental factors.Our results show that the Tianshan Mountains contain several distinct ecological regions,which can be divided into five main vegetation zones from low to high altitudes:mountain desert zone(Hutubi County(HTB):500-1300 m;Qitai County(QT):1000-1600 m),mountain steppe zone(HTB:1400-1600 m;QT:1650-1800 m),mountain forest zone(HTB:1650-2525 m;QT:1850-2450 m),subalpine meadow zone(HTB:2550-2600 m;QT:2500-2600 m),and alpine mat vegetation zone(HTB:2625-2700 m;QT:2625-2750 m).The surface pollen assemblages of different vegetation zones can accurately reflect the characteristics of the mountainous vegetation patterns on the northern slopes of the Tianshan Mountains when excluding the widespread occurrence of Chenopodiaceae,Artemisia,and Picea pollen.Both average annual precipitation(P_(ann))and annual average temperature(T_(ann))affect the distribution of surface pollen assemblages.Moreover,P_(ann) is the primary environmental factor affecting surface pollen assemblages in this region.A significant correlation exists between the pollen percentage and vegetation cover of Picea,Chenopodiaceae,Artemisia,and Asteraceae.Moreover,Picea,Chenopodiaceae,and Artemisia pollen are over-represented compared with their corresponding vegetation cover.The Asteraceae pollen percentage roughly reflects the distribution of a species within the local vegetation.These results have important implications for enhancing our understanding of the relationship between surface pollen assemblages and modern vegetation and climate. | ZHANG Wensheng AN Chengbang LI Yuecong ZHANG Yong LU Chao LIU Luyu ZHANG Yanzhen ZHENG Liyuan LI Bing FU Yang DING Guoqiang | 2023 | Journal of Arid Land2023，15，3： | 0 |
| 14 | Hendecanuclear [Cu_(6)Gd_(5)] magnetic cooler with high molecular symmetry of D_(3h)显示文摘A new family of isostructural 3 d-4 f polymetallic complexes,formulated as [Cu_(6)Ln_(5)(μ_(3)OH)_(9)(C_(4)H_(8)O_(2)N)_(6)(C_(5)H_(4)ON)_(6)(H_(2)O)_(9)]·(ClO_(4))_(6)·(H_(2)O)_(22)(Ln=Pr,1;Nd,2;Sm,3;Eu,4;Gd,5),was successfully isolated through the simple hydrolysis reaction of 2-aminoisobutyric acid,2-hydroxypyridine,Cu(CH_(3)COO)_(2)·H_(2)O,and Ln(ClO_(4))_(3)·6 H_(2)O.Notably,the [Cu_(6)Ln_(5)] clusters with high molecular symmetry of D_(3h) are rare examples of2-aminoisobutyric acid-based 3 d-4 f clusters.The successful theoretical modeling of 5 yielded that the Gd-Gd exchange is of order 0.2 K,whereas the Gd-Cu exchange is an order of magnitude larger.Magnetization data collected for comp lex 5 yield a magnetic entropy change(-ΔSm) of 19.6 J kg^(-1) K^(-1)<1 at 3 K and 7 T,which may be attributed to the weak magnetic interactions between the component metal ions. | Weipeng Chen Guojun Zhou Zhuolun Gou Sen Wang Yuanqi Zhai Tian Han Jurgen Schnack Yanzhen Zheng | 2021 | Chinese Chemical Letters2021，32，2： | 0 |
| 15 | Hybrid Bioelastomer Reinforced by Ultrathin Nanowires of Lanthanide Hydroxycarbonates for Promising Biomedical Applications显示文摘Hybrids composed of biocompatible polymers reinforced with inorganic nanomaterials are useful for many biomedical applications including implantation and tissue regeneration and engineering.In this work,we report a new type of hybrid prepared by doping ultrathin nanowires of lanthanide hydroxycarbonates into classical biocompatible poly(citrates-siloxane).The doping of the inorganic nanowires imparts the hybrids with excellent miscibility with the polymeric matrix,producing hybrids with high elasticity and high tensile strength.The hybrids containing Eu(III)and Gd(III)display their respective luminescence and magnetic properties and thus,offer opportunities to monitor the fate of such hybrids when used in vivo.Insignificant degradation and excellent biocompatibility of these hybrids have also been demonstrated.Together,these favorable traits portend useful applications of the newly developed hybrid elastomers. | Xinyu Zhang Yannan Li Juan Ge Lei Qin Yanzhen Zheng Bo Lei Zhiping Zheng Yaping Du | 2022 | CCS Chemistry2022，4，3： | 0 |
| 16 | Physiological and psychological responses to tended plant communities with varying color characteristics显示文摘Exposure to plants has been reported to promote health and reduce stress,and plant color has direct impacts on physical and mental health.We used images of common types of tended plant communities in Shenyang,China,with combinations of yellow,green,and red foliage,as experimental stimuli.A total of 27 images were used as visual stimuli.We used electroencephalography to measureαwave activity(8-13 Hz)in 40 subjects while they viewed visual stimuli.These data were combined with subjective questionnaire data to analyze the relaxing effect of images of tended plant communities with different color types and proportions on people.The results revealed that,although there were slight differences between the electroencephalography and psychological findings,women were significantly more relaxed than men after viewing the images.Physiological and psychological responses varied with the types and proportions of colors in the tended plant communities:those of foliage with combinations of two or three colors induced stronger responses than images with a single color.Specifically,(1)for one-color plant communities,green or yellow plant communities induced a stronger relaxation effect than red plant communities;(2)for two-color plant communities,the optimal color proportion was 55%+45%,and the green+yellow and green+red color combinations induced a stronger relaxation effect;(3)for three-color plant communities,the relaxation effect was strongest when the color proportion was 55%green+25%yellow+20%red.These data would provide a plant color matching in future plant landscape design,which may be helpful for creating healthy and relaxing environments. | Siyuan Zheng Yanzhen Zhou Haiyan Qu | 2024 | Journal of Forestry Research2024，35，1： | 0 |

| 18 | Process Optimization of Extraction Technique of Polysaccharide from Leaves of Dendrobium officinale显示文摘[Objectives] To optimize the extraction process of polysaccharides from leaves of Dendrobium officinale. [Methods]The polysaccharides from D. officinale were extracted by internal boiling method. The extraction rate of polysaccharides from D. officinale was studied.Based on the single factor experiment,the L_9( 3~3) orthogonal experiment was designed to optimize the extraction process of polysaccharides from D. officinale. [Results]The optimum process for extracting polysaccharides from D. officinale by internal boiling method was as follows:1. 00 g of D. officinale powder was desorbed with 6. 0 mL of 20% ethanol for 20 min,35. 0 mL of 90℃ water was rapidly added,and the extraction time was 5 min. [Conclusions] Under this condition,the extraction rate of polysaccharides from D. officinale was 12. 31%,which was 3. 75 percentage points higher than that of traditional reflux extraction. | Yunying ZHENG Yanzhen YIN Shuming ZHONG Ruirui ZHANG | 2018 | Medicinal Plant2018，9，5： | 0 |
