| 1 | Synthesis and Characterization of Disodium Hydrogen Phosphate Dodecahydrate-Lauric-Palmitic Acid Used for Indoor Energy Storage Floor Units显示文摘Organic and inorganic phase change materials(PCMs) are considered potential materials for thermal energy storage(TES) with different phase change characteristics. In this study, a novel organic-inorganic composite phase change material(PCM) called disodium hydrogen phosphate dodecahydrate-lauric-palmitic acid(D-LA-PACM) was prepared. Expanded graphite(EG) was selected as the support material, and the novel organic-inorganic form-stable PCM called D-LA-PAPCM/EG was prepared using the vacuum adsorption method. Differential scanning calorimetry, Fourier transform infrared spectroscopy, X-ray diffraction, leakage testing, melting and solidification cycle testing, thermal conductivity testing, scanning electron microscopy observation of the micromorphology, and other characterization methods were used to study the microstructure and morphology, thermal physical parameters, thermal conductivity, stability of the PCMs, and the comprehensive material properties of D-LA-PAPCM under the composite action of EG. Results indicated that the melting and freezing temperatures and latent heats of D-LA-PAPCM/EG were measured to be 31.6℃ and 34.3℃ and 142.9 and 142.8 J/g, respectively. Although some of the lauric-palmitic acid(LA-PA) and disodium hydrogen phosphate dodecahydrate(DHPD) separated in the multiple porous structures of EG after 1000 cycles, they could still absorb and release latent heats independently, with D-LA-PAPCM/EG still exhibiting good thermal stability. The thermal conductivity of D-LA-PAPCM/EG was 1.361 W/(m·K). Therefore, the material and thermal properties of the prepared D-LA-PAPCM/EG indicate that it could be well used as a feasible material for energy-saving phase change floor units in indoor TES systems. | XU Qian AKKURT Nevzat ZOU Zhenwei LIU Yang FENG Junxiao YU Chuqiao DING Chong XIONG Yaxuan ZHOU Jingzhi ZANG Yong DING Yulong | 2020 | Journal of Thermal Science2020，29，2： | 4 |
| 2 | Quality analysis of the campaign GPS stations observation in Northeast and North China显示文摘TEQC is used to check the observations quality of 173 GPS campaign stations in the Northeast and North China. Each station was observed with an occupation of 4 days. The quality of the 692 data files is analyzed by the ratio of overall observations to possible observations, MP1, MP2 and the ratio of observations to slips. The reasons for multipath and cycle slips can be derived from the photos taken in the field. The results show that the coverage of trees and buildings/structures, and the interference of high-voltage power lines near the stations are the main reasons. In a small area, the horizontal velocity field in the period 2011—2013 is exemplified, where the magnitudes and directions of the 4 stations' rates are clearly different with that of other stations. It seems that the error caused by the worse environment cannot be mitigated through post processing. Therefore, these conclusions can help the establishment of GNSS stations, measurements, data processing and formulating standards in future. | Yaxuan Hu Lin Cheng Xiong Wang | 2016 | Geodesy and Geodynamics2016，7，2： | 2 |

| 6 | Effect of the Mixing Structure Parameters of a Self-reflux Burner on Combustion Characteristics and NO_(x)Emission显示文摘To solve the problem of low efficiency of NO_(x)emission reduction in self-reflux burners,this study is based on the concept of coordinated control of self-reflux burner structural and thermal parameters.After completing the structural design and optimization of thermal parameters,we continue to adjust the two key structural parameters:the nozzle axis distance and the length of the cylindrical section,to minimize NO_(x)emissions.These are the two parameters that chiefly affect the mixing of flue gas and fuel gas.The results show that increasing nozzle axis distance can delay the mixing of gas and air and create a more uniform oxygen concentration field for the combustion process.The maximum combustion temperature is reduced from 1973.65 K to 1935.88 K and the volume fraction of NO_(x)in the flue gas is reduced from 188.08×10^(–6)to 143.47×10^(–6).However,compared with the nozzle axis distance,the length of the cylindrical section of the burner has little effect on the mixing of the flow field.Under different cylindrical section lengths,the maximum combustion temperature does not change more than 3 K,and the volume fraction of NO_(x)in the flue gas changes within 5×10~(–6). | XU Qian SHEN Meng SHI Kejian LIU Zhihui AKKURT Nevzat XIONG Yaxuan LIU Lin FENG Junxiao WANG Jiulong | 2021 | Journal of Thermal Science2021，30，4： | 0 |
| 7 | Restoration of FMRP expression in adult V1 neurons rescues visual deficits in a mouse model of fragile X syndrome显示文摘Many people affected by fragile X syndrome(FXS)and autism spectrum disorders have sensory processing deficits,such as hypersensitivity to auditory,tactile,and visual stimuli.Like FXS in humans,loss of Fmr1 in rodents also cause sensory,behavioral,and cognitive deficits.However,the neural mechanisms underlying sensory impairment,especially vision impairment,remain unclear.It remains elusive whether the visual processing deficits originate from corrupted inputs,impaired perception in the primary sensory cortex,or altered integration in the higher cortex,and there is no effective treatment.In this study,we used a genetic knockout mouse model(Fmr1^(KO)),in vivo imaging,and behavioral measurements to show that the loss of Fmr1 impaired signal processing in the primary visual cortex(V1).Specifically,Fmr1^(KO) mice showed enhanced responses to low-intensity stimuli but normal responses to high-intensity stimuli.This abnormality was accompanied by enhancements in local network connectivity in V1 microcircuits and increased dendritic complexity of V1 neurons.These effects were ameliorated by the acute application of GABAA receptor activators,which enhanced the activity of inhibitory neurons,or by reintroducing Fmr1 gene expression in knockout V1 neurons in both juvenile and young-adult mice.Overall,V1 plays an important role in the visual abnormalities of Fmr1^(KO) mice and it could be possible to rescue the sensory disturbances in developed FXS and autism patients. | Chaojuan Yang Yonglu Tian Feng Su Yangzhen Wang Mengna Liu Hongyi Wang Yaxuan Cui Peijiang Yuan Xiangning Li Anan Li Hui Gong Qingming Luo Desheng Zhu Peng Cao Yunbo Liu Xunli Wang Min-hua Luo Fuqiang Xu Wei Xiong Liecheng Wang Xiang-yao Li Chen Zhang | 2022 | Protein & Cell2022，13，3： | 0 |
| 8 | Modelling of the electronic and ferroelectric properties of trichloroacetamide using Monte Carlo and first-principles calculations显示文摘The electronic structure and ferroelectric mechanism of trichloroacetamide were studied using first principles calculations and density functional theory within the generalized gradient approximation.Using both Bader charge and electron deformation density,large molecular spontaneous polarization is found to originate from the charge transfer cause by the strong“push-pull”effect of electron-releasing interacting with electron-withdrawing groups.The intermolecular hydrogen bonds,Ne-H…O,produce dipole moments in adjacent molecules to be aligned with each other.They also reduce the potential energy of the molecular chain threaded by hydrogen bonds.Due to the symmetric crystalline properties,however,the polarization of trichloroacetamide is mostly compensated and therefore small.Using the Berry Phase method,the spontaneous polarization of trichloroacetamide was simulated,and good agreement with the experimental values was found.Considering the polarization characteristics of trichloroacetamide,we constructed a one-dimensional ferroelectric Hamiltonian model to calculate the ferroelectric properties of TCAA.Using the Hamiltonian model,the thermal properties and ferroelectricity of trichloroacetamide were studied using the Monte Carlo method,and the Tc value was calculated. | Yaxuan Cai Shijun Luo Zhao Wang Juan Xiong Haoshuang Gu | 2017 | Journal of Materiomics2017，3，2： | 0 |
