| 1 | The effect of nitrogen annealing on lithium ion intercalation in nickel-doped lithium trivanadate显示文摘The communication reports an exploratory experimental study on the effects of nitrogen annealing on lithium ion intercalation in nickel-doped lithium trivanadate cathodic electrodes for lithium ion batteries. It shows good rate performance with discharge capacities of 348.6,252.6, 191.9 and 96.7 m Ah g^(-1)at 0.2, 0.5, 1 and 5 C,respectively. Nitrogen annealing resulted in the formation of parasitic secondary-phase Li V_2O_5 and appreciably increased tetravalent vanadium ions compensated with oxygen vacancies, which would enhance the electronic conductivity and lithium ion diffusivity and promote the interface interaction and deintercalation process, and thus lead to the enhanced lithium ion intercalation properties.The possible impacts of the parasitic secondary-phase Li V_2O_5 on the lithium ion intercalation performance have also been discussed. | Yaguang Liu Cuiping Zhang Chaofeng Liu Huanqiao Song Xihui Nan Guozhong Cao | 2016 | Science Bulletin2016，61，8： | 4 |
| 2 | Coherent Mn3O4-carbon nanocomposites with enhanced energy-storage capacitance显示文摘Nanostructured Mn 3 O 4 被新奇 sonochemical 反应介绍给激活的 C (交流) ,并且产生 nanocomposites 作为 supercapacitor 电极被检验。sonication 不仅催化氧化还原作用反应而且支持了先锋的散开,与 Mn 3 在 AC 的 mesopores 内成年、一致地分布式的 O 4 nanoparticles。另外,在 sonochemical 合成的极端本地条件产出二价的锰离子和氧空缺的过多的数量。这新奇微观结构赋予了样品以优异表演,包括与为以 100 mA/g 的控告 / 解除率的交流的 93 F/g 的价值相比的 150 F/g 的一个特定的电容。一个 Li 离子电容器交付了 68 Wh/kg 的精力密度,与为在 210 W/kg 的力量密度的交流电容器的 41 Wh/kg 相比。 | Chaofeng Liu Huanqiao Song Changkun Zhang Yaguang Liu Cuiping Zhang Xihui Nan Guozhong Cao | 2015 | Nano Research2015，8，10： | 2 |
| 3 | Transcriptome Analysis and Physiological Responses of Economic Macroalga Gracilariopsis lemaneiformis under Sulfate Deficiency显示文摘Sulfur is an essential macronutrient for the growth of all photosynthetic organisms and plays important roles in different metabolic pathways.However,sulfur metabolism and its related research on macroalgae with important ecological value is rather limited.In this study,marine ecological valued macroalga Gracilariopsis lemaneiformis was used to study the general physiological responses and transcriptome profiling under the sulfate deficiency.The relative growth rate of algae under sulfate deficiency was statistically significantly lower than that of control after 6 days.However,no significant differences were observed in the pigments content and Fv/Fm value,indicating that the photosynthesis was not obviously affected under the sulfate deficiency.Furthermore,the significantly increased soluble protein and carbohydrate contents,and indistinctively differentially expressed sulfate transporter/permease(ST)and ATP sulfurylase(ATPS)genes suggesting that G.lemaneiformis cells did not use sulfur from internal protein and carbohydrate pools but utilize stored sulfur from vacuole to satisfy their nutritional requirements during the sulfate deficiency.Transcriptome data showed that most annotated differentially expressed genes(DEGs)were down-regulated under the sulfate deficiency,including a large proportion of genes involved in the pathway of sulfur metabolism.Therefore,it was concluded that the pathway of sulfur metabolism was suppressed under the sulfate deficiency in G.lemaneiformis.The results and analysis in this study provide a comprehensive understanding for the physiological and molecular response of G.lemaneiformis to sulfate deficiency. | Haojie Jia Hong Du Muhmmad Aslam Tangcheng Li Canqi Zheng Xihui Xie Nan Huang Honghao Liang Pengbing Pei Ping Li Weizhou Chen Xiaojuan Liu | 2023 | Phyton-International Journal of Experimental Botany2023，92，1： | 0 |
