| 1 | To inhibit coffee ring effect in inkjet printing of light-emitting polymer films by decreasing capillary force显示文摘Polymer thin film with uniform thickness and flat surface profile is the key point for polymer light emitting diodes(PLEDs) by inkjet printing. However, the coffee ring effect is usually observed due to the mismatch between the evaporation of the solvent and the decrease of solution volume, which promotes the formation of radial flow from the interior of the drop to the edge. In this paper, coffee ring effects of inkjet printed poly(spirobifluorene) films were proposed to be restrained by decreasing capillary force by adding co-solvent with high boiling point and high viscosity to the main solvent. The low evaporation rate of the co-solvent can reduce the driving force of the radial flow; meanwhile the high viscosity of the co-solvent can increase the resistance of the radial flow. Thus, polymer films with improve uniformity can be obtained due to the suppression of the radial flow. The device performance was greatly improved under the condition of proper film thickness and film uniformity and the maximum luminous efficiency of devices with inkjet printed poly(spirobifluorene) can reach 80% of the spin-coated devices. | Xinhong Yu Rubo Xing Zhongxiang Peng Yangming Lin Zhonghui Du Junqiao Ding Lixiang Wang Yanchun Han | 2019 | Chinese Chemical Letters2019，30，1： | 4 |
| 2 | Amplitude of low-frequency fluctuations on Alzheimer’s disease with depression: evidence from resting-state fMRI显示文摘Background The prevalence of Alzheimer's disease(AD)comorbid with depression is common.However,the mechanisms of AD with depression remain unclear.Aims To investigate the regional alterations of brain activity of AD with depression in resting-state functional magnetic resonance imaging(rs-fMRI).Methods 154 patients with AD who met the inclusion criteria were recruited from the Zhejiang Provincial People’s Hospital from October 2014 to October 2016.According to whether the core symptoms of depression were present,patients were divided into two groups,22 patients with AD with depression(AD-D)and 52 patients with AD without depression(AD-nD).The amplitude of low frequency fluctuations(ALFF)was compared between two groups by performing independent-samples f-test.Results Compared with the AD-D group,increased ALFF values in the bilateral superior frontal gyrus,left middle frontal gyrus and left inferior frontal gyrus were observed in the AD-nD group.The brain activity in the AD-nD group in the bilateral superior frontal gyrus,left middle frontal gyrus and the left inferior frontal gyrus was higher than the AD-D group.Conclusions Resting-state brain functional alterations may be closely bound up with the pathophysiologic features of patients with AD with depressive symptoms. | Yuzhu Mu Yumei Li Qi Zhang Zhongxiang Ding Mei Wang Xingguang Luo Xiaoyun Guo Maosheng Xu | 2020 | General Psychiatry2020，33，4： | 1 |
| 3 | Effects of heavy metal ions Cu^(2+)/Pb^(2+)/Zn^(2+)on kinetic rate constants of struvite crystallization显示文摘Struvite(MAP)crystallization technology is widely used to treat ammonia nitrogen in waste effluents of its simple operation and good removal efficiency.However,the presence of heavy metal ions in the waste effluents causes problems such as slow crystallization rate and small crystal size,limiting the recovery rate and economic value of the MAP.The present study was conducted to investigate the effects of concentrations of three heavy metal ions(Cu^(2+),Zn^(2+),and Pb^(2+))on the crystal morphology,crystal size,average growth rate,and crystallization kinetics of MAP.A relationship was established between the kinetic rate constant Ktcalculated by the chemical gradient model and the concentrations of heavy metal ions.The results showed that low concentrations of heavy metal ions in the solution created pits on the MAP surface,and high level of heavy metal ions generated flocs on the MAP surface,which were composed of metal hydroxides,thus inhibiting crystal growth.The crystal size,average growth rate,MAP crystallization rate,and kinetic rate constant Ktdecreased with the increase in heavy metal ion concentration.Moreover,the Ktdemonstrated a linear relationship with the heavy metal concentration ln(C/C~*),which provided a reference for the optimization of the MAP crystallization process in the presence of heavy metal ions. | Guangyuan Chen Tong Zhou Meng Zhang Zhongxiang Ding Zhikun Zhou Yuanhui Ji Haiying Tang Changsong Wang | 2023 | Chinese Journal of Chemical Engineering2023，57，5： | 0 |

Combined with the characteristics and shortcomings,it came up with pertinent recommendations for new urbanization of Feixi County. | Jinyan DING Zhongxiang YU | 2017 | Asian Agricultural Research2017，9，4： | 0 |
| 5 | NAD^(+) and its possible role in gut microbiota:Insights on the mechanisms by which gut microbes influence host metabolism显示文摘Nicotinamide adenine dinucleotide(NAD^(+))is an enzyme cofactor,co-substrate,and redox factor in all living cells and is necessary for maintaining cell metabolism.It has been shown that appropriate supplementation of NAD^(+)precursors or inhibition of NAD^(+)-depleting enzymes can promote mitochondrial oxidative phosphorylation and improve host energy utilization efficiency.In addition,increasing evidence indicates that the gut microbiota plays a pivotal role in host metabolism.Theoretically,there should be a close correlation among NAD^(+),gut microbiota,and host metabolism;however,the information is limited.In this review,we summarize the metabolic process of NAD^(+)and its impact on host metabolism,the link between gut microbiota and host metabolism,as well as the potential effects of NAD^(+)on microbial metabolism,providing a new perspective on the interaction between gut microbiota and host metabolism. | Zhongxiang Ren Yetong Xu Tiejun Li Weizhong Sun Zhiru Tang Yongsheng Wang Kaifeng Zhou Jigang Li Qi Ding Kaiyang Liang Liuting Wu Yulong Yin Zhihong Sun | 2022 | Animal Nutrition2022，，3： | 0 |
