5Effects of Nano-CaCO_(3)Addition on Properties of Corundum-based Dispersive Purging Plugs显示文摘In order to improve the properties of corundum based dispersive purging plugs,dispersive purging plug specimens were prepared using tabular corundum(1-0.15 and≤0.15 mm)as the aggregates,tabular corundum(≤0.044 mm)andα-Al_(2)O_(3)micropowder(d_(50)=0.6μm)as the matrix,Secar 71 cement as the binder,introducing different amounts of nano-CaCO_(3),casting into shapes,and firing at different temperatures(1200 or 1600℃)for 4 h.The effects of the nano-CaCO_(3) extra-addition(0,0.5%,1.0%,1.5%and 2.0%,by mass)on the consistency of the castables as well as the properties and microstructure of the dispersive purging plug specimens were studied.The results show that:(1)with the fixed water addition,the consistency of the corundum castables decreases as the nano-CaCO_(3)addition increases;(2)with the increasing nano-CaCO_(3)addition,the bulk density of the specimens fired at different temperatures for 4 h decreases,the apparent porosity,the cold strength and the hot modulus of rupture all increase,the gas permeability does not change significantly;(3)the specimens fired at 1600℃ for 4 h have obviously better cold comprehensive performance than those fired at 1200℃for 4 h;(4)when the nano-CaCO_(3)addition is 1.5%,the comprehensive performance of the specimen is the optimal.SU Yuqing ZHU Yening YU Baisong XI Zijian WEI Juncong TU Junbo ZHANG Houxing WANG Yilong 2023China's Refractories2023,32,4:0
6In situ TEM visualization of Ag catalysis in Li-O_(2)nanobatteries显示文摘Lithium-oxygen(Li-O_(2))batteries have been considered as an ideal solution to solving the global energy crisis.Silver(Ag)and Agbased catalyst have been extensively studied due to their high catalytic activities in Li-O_(2)batteries.However,it remains a challenge to track the catalytic mechanism during the charge/discharge process.Here,a nanoscale processing method was used to assemble a Li-O_(2)nanobattery in an aberration-corrected environmental transmission electron microscope(ETEM),where a single Ag nanowire(NW)was used as catalyst for O_(2)electrode.A visualization of the lithium ion insertion process during the electrochemical reactions was achieved in this nanobattery.Numerous Ag nanoparticles(NPs)were observed on the surface of the Ag NW,which were covered by the discharge product Li2O_(2).By simultaneously studying the evolution of the interface and the phase transformation,it can be concluded that these Ag NPs wrapped around Ag NW acted as catalyst during the subsequent charge/discharge reaction.Based on these studies,Ag NPs decorated on porous carbon were synthesized,it can simultaneously improve the cycling stability(100 cycles)and the maximum specific capacity(17,371 mAh·g^(−1)at a current density of 100 mA·g^(−1))in a coin cell Li-O_(2)battery.This study suggests that nanoscale Ag may be a promising catalyst for Li-O_(2)battery.Yixuan Wen Shuaijun Ding Chongchong Ma Peng Jia Wei Tu Yunna Guo Shuang Guo Wei Zhou Xiaoqian Zhang Jianyu Huang Liqiang Zhang Tongde Shen Yuqing Qiao 2023Nano Research2023,16,5:0
7Development of Heat Tolerant Two-Line Hybrid Rice Restorer Line Carrying Dominant Locus of OsHTAS显示文摘In order to create novel germplasm resources for breeding heat tolerant variety,we transferred a dominant allele OsHTAS,previously characterized and cloned from a high-temperature tolerant local variety HT54,which was collected from the rice production area of southern China,into a high-temperature sensitive intermediate breeding line HT13 through six rounds of successive backcross by using marker-assisted selection.The molecular analysis showed that the recovery of genetic background of a resultant near isogenic line(NIL),MHT13,was around 99.8%.The OsHTAS gene introduced in the MHT13 expressed normally in the HT13 genetic background,mediating heat tolerance and phenotype similar to those of the donor parent HT54.The major agronomic traits of MHT13 resembled those of the recurrent parent HT13.Moreover,MHT13 had high general combining ability and its rice quality reached the grade 3 standard of edible high-quality rice issued by Ministry of Agriculture of the People’s Republic of China,which greatly improved its application value in rice production.Mehmood Jan Gulmeena Shah Huang Yuqing Liu Xuejiao Zheng Peng Du Hao Chen Hao Tu Jumin 2021Rice science2021,28,1:0
8Mitigating growth-stress tradeoffs via elevated TOR signaling in rice显示文摘Rice production accounts for approximately half of the freshwater resources utilized in agriculture,result-ing in greenhouse gas emissions such as methane(CH4)from flooded paddy fields.To address this chal-lenge,environmentally friendly and cost-effective water-saving techniques have become widely adopted in rice cultivation.However,the implementation of water-saving treatments(WsTs)in paddy-field rice has been associated with a substantial yield loss of up to 50%as well as a reduction in nitrogen use efficiency(NUE).In this study,we discovered that the target of rapamycin(TOR)signaling pathway is compromised in rice under WsT.Polysome profiling-coupled transcriptome sequencing(polysome-seq)analysis unveiled a substantial reduction in global translation in response to WST associated with the downregulation of TOR activity.Molecular,biochemical,and genetic analyses revealed new insights into the impact of the positive TOR-S6K-RPS6 and negative TOR-MAF1 modules on translation repression under WST.Intriguingly,ammonium exhibited a greater ability to alleviate growth constraints under WsT by enhancing TOR signaling,which simultaneously promoted uptake and utilization of ammonium and nitrogen allocation.We further demonstrated that TOR modulates the ammonium transporter AMT1;1 as well as the amino acid permease APP1 and dipeptide transporter NPF7.3 at the translational level through the 5'untranslated region.Collectively,these findings reveal that enhancing TOR signaling could mitigate rice yield penalty due to WST by regulating the processes involved in protein synthesis and NUE.Our study will contribute to the breeding of new rice varieties with increased water and fertilizer utilization efficiency.Wei Li Jiaqi Liu Zeqi Li Ruiqiang Ye Wenzhen Chen Yuqing Huang Yue Yuan Yi Zhang Huayi Hu Peng Zheng Zhongming Fang Zeng Tao Shiyong Song Ronghui Pan Jian Zhang Jumim Tu Jen Sheen Hao Du 2024Molecular Plant2024,17,2:0
