The anode-free design is a promising strategy to increase the energy density of aqueous Zn metal batteries(AZMBs).However,the scarcity of Zn-rich cathodes and the rapid loss of limited Zn greatly hinder their commercial applications.To address these issues,a novel anode-free Zniodine battery(AFZIB)was designed via a simple,low-cost and scalable approach.Iodine plays bifunctional roles in improving the AFZIB overall performance:enabling high-performance Zn-rich cathode and modulating Zn deposition behavior.On the cathode side,the ZnI_(2) serves as Zn-rich cathode material.The graphene/polyvinyl pyrrolidone heterostructure was employed as an efficient host for ZnI_(2) to enhance electron conductivity and suppress the shuttle effect of iodine species.On the anode side,trace I_(3)^(−) additive in the electrolyte creates surface reconstruction on the commercial Cu foil.The in situ formed zincophilic Cu nanocluster allows ultralow-overpotential and uniform Zn deposition and superior reversibility(average coulombic efficiency>99.91% over 7,000 cycles).Based on such a configuration,AFZIB exhibits significantly increased energy density(162 Wh kg^(−1)) and durable cycle stability(63.8% capacity retention after 200 cycles)under practical application conditions.Considering the low cost and simple preparation methods of the electrode materials,this work paves the way for the practical application of AZMBs.

Spatiotemporal characterization and regional contributions of O3 and NO2:An investigation of two years of monitoring data in Henan,China

引用

Journal of Environmental Sciences 2020年第4期32卷 29-40页

作者： Shijie Yu Shasha Yin Ruiqin zhang Lingling Wang Fangcheng Su yixiang zhang Jian Yang Research Institute of Environmental Science College of Chemistry and Molecular EngineeringZhengzhou UniversityZhengzhou450001China Henan Environment Monitoring Centre Zhengzhou450004China

To investigate the characteristics of ground level ozone(O3)for Henan Province,the ambient air quality monitoring data of 2015 and 2016 were analyzed.The result showed that the 8 h-max-O3 concentrations displayed a distinct seasonality,where the maximum and minimum values,averaging 140.41,54.19μg/m3,occurred in summer and winter,respectively.There is a significant correlation between meteorological factors and O3 concentration.The Voronoi neighborhood averaging analysis indic ated that O3,temperature,and ultraviolet radiation in Henan province were decreased from northwest to southeast,while relative humidity and precipitation displayed the opposite trend.Besides meteorological factors,the chemical processes play an essential role in ozone formation.Reactions of NO,NO2 and O3 form a closed system,and the partitioning point of the OX-component(O3+NO2)was at 40 and 80μg/m3 for nitrogen oxide(NOx)in winter and summer,respectively,with NO2 dominating at higher NOx pollution and O3 being the m ajor component at lower levels.The relationship between oxidant(OX=O3+NO2)and NOx concentrations were evaluated to understand the regional and local contribution of OX.It showed that high regional contribution occurred in the spring,whereas the highest local contribution lead to the summer peak of O3 observed in Zhengzhou.This present study reveals important environment impacts from the photochemical process and the meteorological conditions in the region with better understanding on the O3 characterization.

作者： Xiaobin Shi Di Zhou yixiang zhang Open Laboratory of Marginal Sea Geology and Paleoenvironment South China Sea Institute of Oceanology Chinese Academy of Sciences Guangzhou China

Thermal structures of three deep seismic profiles in the continental margin in the northern South China Sea are calculated, their 'thermal' lithospheric thicknesses are evaluated based on the basalt dry solidus, and their rheological structures are evaluated with linear frictional failure criterion and power-law creep equation. 'Thermal' lithosphere is about 90 km in thickness in shelf area, and thins toward the slope, lowers to 60-65 km in the lower slope, ocean crust and Xisha Trough. In the mid-west of the studied area, the lithospheric rheological structure in shelf area and Xisha Islands is of four layers: brittle, ductile, brittle and ductile. Because of uprising of heat mantle and thinning of crust and lithosphere in Xisha Trough, the bottom of the upper brittle layer is only buried at 16 km. In the eastern area, the bottom of the upper brittle layer in the north is buried at 20 km or so, while in lower slope and ocean crust, the rheological structure is of two layers of brittle and ductile, and

Charcoal stove is widely used in the developing countries especially in Africa and Central America.Even reported to have a high impact on human health,stoves promoted in the related areas still mainly focus on fuel saving and little knowledge was reported for the stove performance in the field.This research evaluated four commercialized charcoal stoves with clay baseline stove using a modified Chinese cooking stove protocol that considered the local cooking habit to make the testing results more useful for the local stove promotion.The results showed that the thermal efficiency of tested charcoal stoves ranged from 38.7%to 47.5%,and the cooking power was around 640-1200 W.The CO emission factors of the improved stove had a 60%reduction compared with baseline stove.Different indicators reporting the same aspect of the stove were evaluated,and it suggested choosing the indicators according to the project requirements.

A Novel Composite Skin Graft Technique with Fat Derivatives

引用

Chinese Journal Of Plastic and Reconstructive Surgery 2021年第2期3卷 82-84页

作者： yixiang zhang Bin FANG Yun XIE Department of Plastic and Reconstructive Surgery Shanghai Ninth People’s HospitalShanghai Jiao Tong University School of MedicineShanghai 200011China

Skin grafting,although a relatively classic and well-known technique,still has multiple disadvantages such as secondary contracture of the skin graft,sunken depression,poor elasticity,and color mismatch.Adding adipose tissues significantly improved the graft appearance compared to traditional skin grafting methods.Herein,we report two cases of modified skin graft procedures,both showing positive outcomes.In case 1,a mechanically processed fat-derived product was injected into the lower half of the skin graft area.In case 2,left upper eyelid blepharoplasty was performed,and the orbital fat strip was transferred and placed under the recipient area on the right side.Hair growth was observed only in case 1,whereas the extent of sunken depression was significantly reduced in both cases.Compared to traditional skin grafting methods,adding fat components to the skin graft recipient area improved the appearance and blood supply,together with enhancing the regenerative rate.

电力负荷数据的多样性与复杂性,会导致负荷预测过程中出现超参数难以确定、拟合效果较差和预测精度不高等问题。针对以上问题,提出一种基于樽海鞘群算法的融入注意力机制的双向长短期记忆神经网络模型——SSA-AM-BiLSTM模型。该模型使用BiLSTM学习特征的内部变化规律,引入注意力机制为特征进行权重分配,并且利用樽海鞘群算法优化网络超参数。基于具体数据集进行的负荷预测仿真实验表明,相较于GRU、LSTM、AM-BiLSTM和PSO-AM-BiLSTM模型,所提出的SSA-AM-BiLSTM模型的MAPE分别减少了2.15%、1.93%、1.42%和0.45%,并且优化了拟合效果,显著提高了预测精度。
