| 1 | Effect of growth time on morphology and photovoltaic properties of ZnO nanowire array films显示文摘Single-crystalline ZnO nanowire arrays with different aspect ratios and nanowire densities were prepared by the hydrothermal growing method using polyethyleneimine (PEI) as a surfactant. PEI can only hinder the lateral growth of the ZnO nanowires, which is observed by high resolution transmission electron microscopy (HRTEM) analysis. Dye-sensitized solar cells were assembled by the ZnO nanowire arrays with different thicknesses, which can be controlled by the growing time and characterized using photocurrent-voltage measurements. Their photocurrent densities and energy allover conversion efficiencies increased with increasing ZnO nanowire lengths. Short-circuit current den-sity of 4.31 mA-cm-2 and allover energy conversion efficiency of 0.87% were achieved with 12.9-μm-long ZnO nanowire arrays. | YANG Weiguang WANG Yali ZHEN Qiang SHI Weimin | 2011 | Rare Metals2011,30,6: | 4 |
| 2 | Synthesis of Single-Crystalline Anatase TiO_2 Nanorods With High-Performance Dye-Sensitized Solar Cells显示文摘Single-crystalline anatase TiO_2 nanorods have been prepared by solvothermal method using tetrabutylammonium hydroxide(TBAH) as a morphology controlling agent.The obtained TiO_2 nanorods are dominated by a large percentage of {010} facets.The power conversion efficiency of dye-sensitized solar cell(DSSC) based on anatase TiO_2 nanorods(8.66%) exhibits a significant improvement(35%) compared to that of P25 TiO_2(5.66%).The high performance of the anatase TiO_2 nanorods solar cell is ascribed to their large percent of exposed {010} facets as well as balancing their surface areas and sizes. | Jin Liu Jun Luo Weiguang Yang Yali Wang Linyan Zhu Yueyang Xu Ying Tang Yajing Hu Chen Wang Yigang Chen Weimin Shi | 2015 | Journal of Materials Science & Technology2015,31,1: | 2 |
| 3 | The effects of two free-floating plants (Eichhornia crassipes and Pistia stratiotes) on the burrow morphology and water quality characteristics of pond loach (Misgurnus anguillicaudatus) habitat显示文摘Loach exhibit conspicuous drilling behaviors in the mud of shallow waters,yet their burrow morphology and the factors affecting this behavior have received little attention.We characterized the burrow morphology and water quality of the pond loach Misgurnus anguillicaudatus in three scenarios:in tanks without plants,tanks with the free-floating plant water hyacinth Eichhornia crassipes,and tanks with water lettuce Pistia stratiotes.Water hyacinth effectively removed water TN,COD,NO3-N and NH4-N,and water lettuce removed water TP and NH4-N.Water hyacinth and water lettuce markedly reduced water turbidity and DO,increased TOC and EC.Water hyacinth purified water more effectively than water lettuce,providing a suitable habitat for loach feeding,living and burrowing.The burrow structures were V-shaped,Y-shaped,inverted L-shaped,or complicated dendritic networks composed of multiple V shapes.The hyacinth treatment was characterized by the greatest burrow volume,length,depth,and structural complexity,but the opening size was reduced by dense root mat coverage.Burrows in the water lettuce treatment were characterized by intermediate volume,length,branches and sinuosity,but they had the largest opening and pit size.The control treatment had a flat bottom with the smallest,shortest burrows.This study indicates that free-floating plants improve habitat suitability and change burrow morphology and may be used to improve loach breeding methods。 | Jinqing Wang Guihua Fu Weiyue Li Ying Shi Jicai Pang Qiang Wang Weiguang Lü Change Liu Jiansheng Liu | 2018 | Aquaculture and Fisheries2018,3,1: | 2 |
| 4 | Corrosion Mechanism of E-glass of Chemical Resistance Glass Fiber in Acid Environment显示文摘The corrosion of ECR glass fiber was investigated by the analysis methods of weight loss ratio under different acids and at various durations.Weight loss,leaching of cations,and surface composition of ECR glass fiber were analyzed.The corrosion mechanism of ECR glass fiber in acid environment was also discussed.The experimental results showed that the corrosion degree of ECR glass fiber in different acids obeyed the order: HNO_3>H_2SO_4>HCl.The acid effects on corrosion of ECR glass fiberis were totally different.Hydrochloric acid mainly destroyed the network structure of [AlO_4],while sulfuric acid and nitric acid mainly destroyed the structure of [SiO_4].The acid resistance of ECR glass fiber is much better than that of E glass fiber due to the generation of intermediate product silicic acid gel Si(OH)_4 during ion exchange.It can adhere to the glass surface to form a thin film and hinder the proceeding of corrosion. | 谢俊 YIN Peng SHI Weiguang HU Min 王静 ZHOU Xuedong HAN Jianjun CAO Shaowen HAN Lixiong YAO Yuan | 2016 | Journal of Wuhan University of Technology(Materials Science)2016,31,4: | 1 |

| 6 | Synthesis and Properties of Dendritic Long-Chain Esters as Crude Oil Flow Improver Additives显示文摘The efficiencies of 6 kinds of macromolecules with dendritic structure in improving the flow properties of crude oil were investigated. The dendritic additives were synthesized using low-generation dendritic poly(amidoamine) and alkyl longchain acrylic esters as starting materials, and their structures were characterized by the Fourier transform infrared spectroscopy, 1H-nuclear magnetic resonance and elemental analysis. The effects on the pour point and rheological properties of crude oil samples were studied. Efficiencies of dendritic long-chain esters were not only influenced by the alky chain length, but also by the generation of dendrimer. The longer the alkyl chain of dendritic long-chain ester was, the better the effect in the reduction of pour point and apparent viscosity was. Efficiencies of 1.5 generation dendritic long-chain ester with 8 branched chains for the reduction of pour point and apparent viscosity were superior to those of 0.5 generation dendritic long-chain ester with 4 branched chains. Under the same conditions, efficiencies of 1.5 generation dendritic eighteen ester were superior to those of other 1.5 generation dendritic long-chain esters for the reduction of pour point and viscosity of crude oil. | Li Cuiqin Sun Peng Shi Weiguang Wang Jun | 2016 | China Petroleum Processing & Petrochemical Technology2016,18,1: | 1 |

| 9 | Hybrid Neural Network for Automatic Recovery of Elliptical Chinese Quantity Noun Phrases显示文摘In Mandarin Chinese,when the noun head appears in the context,a quantity noun phrase can be reduced to a quantity phrase with the noun head omitted.This phrase structure is called elliptical quantity noun phrase.The automatic recovery of elliptical quantity noun phrase is crucial in syntactic parsing,semantic representation and other downstream tasks.In this paper,we propose a hybrid neural network model to identify the semantic category for elliptical quantity noun phrases and realize the recovery of omitted semantics by supplementing concept categories.Firstly,we use BERT to generate character-level vectors.Secondly,Bi-LSTM is applied to capture the context information of each character and compress the input into the context memory history.Then CNN is utilized to capture the local semantics of n-grams with various granularities.Based on the Chinese Abstract Meaning Representation(CAMR)corpus and Xinhua News Agency corpus,we construct a hand-labeled elliptical quantity noun phrase dataset and carry out the semantic recovery of elliptical quantity noun phrase on this dataset.The experimental results show that our hybrid neural network model can effectively improve the performance of the semantic complement for the elliptical quantity noun phrases. | Hanyu Shi Weiguang Qu Tingxin Wei Junsheng Zhou Yunfei Long Yanhui Gu Bin Li | 2021 | Computers, Materials & Continua2021,,12: | 0 |
| 10 | Mulberry leaf flavonoids activate BAT and induce browning of WAT to improve type 2 diabetes via regulating the AMPK/SIRT1/PGC-1α signaling pathway显示文摘Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF’s anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D. | CHENG Long SHI Lu HE Changhao WANG Chen LV Yinglan LI Huimin AN Yongcheng DUAN Yuhui DAI Hongyu ZHANG Huilin HUANG Yan FU Wanxin SUN Weiguang ZHAO Baosheng | 2023 | Chinese Journal of Natural Medicines2023,21,11: | 0 |
