2Recent progress in graphene-based electrodes for flexible batteries显示文摘The emerging flexible electronic devices have stimulated the development of flexible batteries,in which flexible electrodes are indispensable components.Graphene,known for its excellent electrical conductivity and mechanical stability,can be used as an ideal flexible substrate.Recently,many efforts have been devoted to graphene-based electrodes for flexible batteries.Herein,this review summarizes recent advances in the development of graphene-based electrodes for various flexible batteries,including metal-ion batteries(ions of Li,Na,Zn,Al,etc.),lithiumsulfur batteries,and metal-air batteries(Li-and Zn-air batteries).Besides,major challenges and future developments of flexible batteries are also discussed.Chunlong Dai Guoqiang Sun Linyu Hu Yukun Xiao Zhipan Zhang Liangti Qu 2020InfoMat2020,2,3:9
3Decreased glutathione reductase2 leads to early leaf senescence in Arabidopsis显示文摘Glutathione reductase(GR) catalyzes the reduction of glutathione disulfide(GSSG) to reduced glutathione(GSH)and participates in the ascorbate-glutathione cycle, which scavenges H_2O_2. Here, we report that chloroplastic/mitochondrial GR2 is an important regulator of leaf senescence. Seed development of the homozygous gr2 knockout mutant was blocked at the globular stage. Therefore, to investigate the function of GR2 in leaf senescence, we generated transgenic Arabidopsis plants with decreased GR2 using RNAi. The GR2 RNAi plants displayed early onset of age-dependent and darkand H2O2-induced leaf senescence, which was accompanied by the induction of the senescence-related marker genes SAG12 and SAG13. Furthermore, transcriptome analysis revealed that genes related to leaf senescence, oxidative stress, and phytohormone pathways were upregulated directly before senescence in RNAi plants. In addition, H2O2 accumulated to higher levels in RNAi plants than in wild-type plants and the levels of H_2O_2 peaked in RNAi plants directly before the early onset of leaf senescence. RNAi plants showed a greater decrease in GSH/GSSG levels than wild-type plants during leaf development. Our results suggest that GR2 plays an important role in leaf senescence by modulating H_2O_2 and glutathione signaling in Arabidopsis.Shunhua Ding Liang Wang Zhipan Yang Qingtao Lu Xiaogang Wen Congming Lu 2016Journal of Integrative Plant Biology2016,58,1:5
4Achievement of promising cryogenic magnetocaloric performances in La_(1-x)Pr_(x)Fe_(12)B_(6)compounds显示文摘The magnetic refrigeration(MR)utilizing magnetocaloric effect(MCE)has been recognized as an environmentally friendly and energy efficiency technology.Here we presented the magnetic properties and MCE in Pr-doped La_(1-x)Pr_(x)Fe_(12)B_(6)(x=0.05-0.2)itinerant-electron metamagnetic(IEM)compounds.A small amount of Pr doping La site can greatly improve the peak values in the magnetic entropy change S_(M)(T)curves,especially under relatively low magnetic field changes(ΔH).Additionally,the peak temperature increases gradually and the magnetic hysteresis reduces gradually with increasing x.The observed MCE in present La_(1-x)Pr_(x)Fe_(12)B_(6)compounds is related to its field-induced first-ordered IEM transition.The peak values ofΔS_(M)for La_(1-x)Pr_(x)Fe_(12)B_(6)compounds reach 13.4,15.4,12.5 and 13.0 J/(kg K)at T_(C)~58,68,72and 89 K for x=0.05,0.10,0.15 and 0.2 under H of 0-7 T,respectively.The corresponding relative cooling power values are 462.3,480.7,372.4 and 375.7 J/kg.The present La_(1-x)Pr_(x)Fe_(12)B_(6)compounds could be good candidates for active MR application if the magnetic and thermal hysteresis can be further reduced.The present work indicates that the La Fe_(12)B_(6)-based material system could also exhibit promising magnetocaloric performances.Zhipan Ma Xiaoshi Dong Zhenqian Zhang Lingwei Li 2021Journal of Materials Science & Technology2021,,33:4
5A cross-linked polyacrylamide electrolyte with high ionic conductivity for compressible supercapacitors with wide temperature tolerance显示文摘The development of compressible supercapacitors (SCs) that is tolerant to wide temperature range has been severely hindered due to the poor ionic conductivity and absence of extra functions in conventional polymer electrolytes.Herein,a highly conductive and compressible hydrogel polyelectrolyte has been prepared from polyacrylamide cross-linked by methacrylated graphene oxide (MGO-PAM) and the polyelectrolyte can maintain its excellent elasticity at-30 ℃ as well as its original shape at 100 ℃.As a result,the SC based on the MGO-PAM polyelectrolyte outperformed those fabricated with the conventional poly(vinyl alcohol)(PVA)/H2SO4 electrolyte over a wide temperature window between-30 and 100 ℃.Meanwhile,the device shows an excellent cycling stability (capacitance retention of 93.3% after 8,000 cycles at-30 ℃ and 76.5 % after 4,000 cycles under 100 ℃) and a reversible compressibility (a high capacitance retention of 94.1% under 80% compression).Therefore,the MGO-PAM polyelectrolyte enables the fabrication of compressible SCs with a wide operating temperature,rendering new insights for developing next-generation robust and multifunctional energy-storage devices.Xuting Jin Guoqiang Sun Guofeng Zhang Hongsheng Yang Yukun Xiao Jian Gao Zhipan Zhang Liangti Qu 2019Nano Research2019,12,5:4

7Autophagy targets Hd1 for vacuolar degradation to regulate rice flowering显示文摘Flowering time(heading date)is a critical agronomic trait that determines the yield and regional adaptability of crops.Heading date 1(Hd1)is a central regulator of photoperiodic flowering in rice(Oryza sativa).However,how the homeostasis of Hd1 protein is achieved is poorly understood.Here,we report that the nuclear autophagy pathway mediates Hd1 degradation in the dark to regulate flowering.Loss of autophagy function results in an accumulation of Hd1 and delays flowering under both short-day and long-day conditions.In the dark,nucleus-localized Hd1 is recognized as a substrate for autophagy and is subjected to vacuolar degradation via the autophagy protein OsATG8.The Hd1-0sATG8 interaction is required for autophagic degradation of Hd1 in the dark.Our study reveals a new mechanism by which Hd1 protein homeostasis is regulated by autophagy to control rice flowering.Our study also indicates that the regulation of flowering by autophagic degradation of Hd1 orthologs may have arisen over the course of mesangiosperm evolution,which would have increased their flexibility and adaptability to the environment by modulating flowering time.Zhi Hu Zhipan Yang Yi Zhang Aihong Zhang Qingtao Lu Ying Fang Congming Lu 2022Molecular Plant2022,15,7:3
8Stock assessment for Atlantic yellowfin tuna based on extended surplus production model considering life history显示文摘The modern fishery stock assessment could be conducted by various models,such as Stock Synthesis model with high data requirement and complicated model structure,and the basic surplus production model,which fails to incorporate individual growth,maturity,and fishery selectivity,etc.In this study,the Just Another Bayesian Biomass Assessment(JABBA)Select which is relatively balanced between complex and simple models,was used to conduct stock assessment for yellowfin tuna(Thunnus albacares)in the Atlantic Ocean.Its population dynamics was evaluated,considering the influence of selectivity patterns and different catch per unit effort(CPUE)indices on the stock assessment results.The model with three joint longline standardized CPUE indices and logistic selectivity pattern performed well,without significant retrospective pattern.The results indicated that the stock is not overfished and not subject to overfishing in 2018.Sensitivity analyses indicated that stock assessment results are robust to natural mortality but sensitive to steepness of the stock-recruitment relationship and fishing selectivity.High steepness was revealed to be more appropriate for this stock,while the fishing selectivity has greater influence to the assessment results than life history parameters.Overall,JABBA-Select is suitable for the stock assessment of Atlantic yellowfin tuna with different selectivity patterns,and the assumptions of natural mortality and selectivity pattern should be improved to reduce uncertainties.Zhipan Tian Fei Wang Siquan Tian Qiuyun Ma 2022Acta Oceanologica Sinica2022,41,8:2
9Investigation and Analysis of Understory Vegetation in Casuarina equisetifolia Forests in Northern Hainan Province显示文摘Understory vegetation in the Casuarina equisetifolia forests at different ages was sampled and analyzed fi rstly, and then the structural features, biomass, and distribution characteristics of carbon stock of the understory vegetation, as well as the quantity and thickness of the understory litter were studied. The results show that the understory vegetation in the C. equisetifolia forests is mainly composed of herbaceous plants, and there are nearly no shrubs in the study area. Moreover, the quantity of herbaceous plants rises obviously with the increase of forest age. There is a big difference between the woodlands at different ages in total biomass of herbaceous plants, and the maximum of total biomass can be found in 15-year-old woodland, reaching 1.68 t/hm^2; the biomass of overground parts of herbaceous plants is higher than that of underground parts. There is a big difference between the woodlands at different ages in thickness of the understory litter, and the thickness of understory litter in 10-yearold woodland is the highest, reaching 6.67 cm. The maximum quantity of the understory litter has reached 14.69 t/hm^2, and the thickness of the half decomposed litter is larger than that of the undercomposed litter in most woodlands.XUE Yang YANG Zhongyang WANG Xiaoyan SU Shaofeng LIN Zhipan XU Lina 2016Journal of Landscape Research2016,8,3:2
10Pentatricopeptide repeat protein PHOTOSYSTEM I BIOGENESIS FACTOR2 is required for splicing of ycf3显示文摘To gain a better understanding of the molec-ular mechanisms of photosystem!(PSI)biogenesis,wecharacterized the Arabidopsis thaliana photosystem l bio-genesis factor 2(pbf2)mutant,which lacks PSl complex.PBF2 encodes a P-class pentatricopeptide repeat(PPR)protein.In the pbf2 mutants,we observed a striking de-crease in the transcript level of only one gene,thechloroplast gene ycf3,which is essential for PSl assembly.Further analysis of ycf3 transcripts showed that PBF2 isspecifically required for the splicing of ycf3 intron 1.Computational prediction of binding sequences and elec-trophoretic mobility shift assays reveal that PBF2 specifi-cally binds to a sequence in ycf3 intron 1.Moreover,we found that PBF2 interacted with two general factors forgroup ll intron splicing CHLOROPLAST RNA SPLICING2-AsSOCIATED FACTOR1(CAF1)and CAF2,and facilitated theassociation of these two factors with ycf3 intron 1.Ourresults suggest that PBF2 is specifically required for thesplicing of ycf3 intron 1 through cooperating with CAF1and CAF2.Our results also suggest that additional proteinsare required to contribute to the specificity of CAF-dependent group ll intron splicing.Xuemei Wang Zhipan Yang Yi Zhang Wen Zhou Aihong Zhang Congming Lu 2020Journal of Integrative Plant Biology2020,62,11:2
11Ultrafast Synthesis of Metal-Layered Hydroxides in a Dozen Seconds for High-Performance Aqueous Zn(Micro-)Battery显示文摘Efficient synthesis of transition metal hydroxides on conductive substrate is essential for enhancing their merits in industrialization of energy storage field.However,most of the synthetic routes at present mainly rely on traditional bottom-up method,which involves tedious steps,time-consuming treatments,or additional alkaline media,and is unfavorable for high-efficiency production.Herein,we present a facile,ultrafast and general avenue to synthesize transition metal hydroxides on carbon substrate within 13 s by Joule-heating method.With high reaction kinetics caused by the instantaneous high temperature,seven kinds of transition metal-layered hydroxides(TM-LDHs)are formed on carbon cloth.Therein,the fastest synthesis rate reaches~0.46 cm^(2)s^(-1).Density functional theory calculations further demonstrate the nucleation energy barriers and potential mechanism for the formation of metal-based hydroxides on carbon substrates.This efficient approach avoids the use of extra agents,multiple steps,and long production time and endows the LDHs@carbon cloth with outstanding flexibility and machinability,showing practical advantages in both common and micro-zinc ion-based energy storage devices.To prove its utility,as a cathode in rechargeable aqueous alkaline Zn(micro-)battery,the NiCo LDH@carbon cloth exhibits a high energy density,superior to most transition metal LDH materials reported so far.Xiangyang Li Fangshuai Chen Bo Zhao Shaohua Zhang Xiaoyu Zheng Ying Wang Xuting Jin Chunlong Dai Jiaqi Wang Jing Xie Zhipan Zhang Yang Zhao 2023Nano-Micro Letters2023,15,3:2

17Achieving simultaneous Cu particles anchoring in meso-porous TiO_(2) nanofabrication for enhancing photo-catalytic CO_(2) reduction through rapid charge separation显示文摘A facile solvo-thermal approach was successfully employed to prepare titanium oxide (TiO_(2)) nano-aggregates with simultaneous copper particles anchoring. The as-synthesized composite could convert CO_(2) into CH_(4) and CO products under simulated solar irradiation. The impact of copper loading amounts on the photo-reduction capability was evaluated. It was found proper amount of Cu loading could enhance the activity of CO_(2) photo-reduction. As a result, the optimal composite (TiO_(2)^(-)Cu-5%) consisting of TiO_(2) supported with 5% (mole ratio) Cu exhibits 2.2 times higher CH_(4) yield and 3 times higher CO yield compared with pure TiO_(2). Conduction band calculated from the band gap and valence X-ray photoelectron spectroscopy (XPS) indicated TiO_(2) nano-aggregates have suitable band edge alignment with respect to the CO_(2)/CH_(4) and CO_(2)/CO redox potential. Furthermore, with involving of Cu particles, an efficient separation of photo-generated charges was achieved on the basis of photocurrent response and photoluminescence spectra results, which contributed to the improved photo-catalytic performance. The present work suggested that the Cu-decorated TiO_(2) could serve as an efficient photo-catalyst for solar-driven CO_(2) photo-reduction.Jinyan Xiong Mengmeng Zhang Mengjie Lu Kai Zhao Chao Han Gang Cheng Zhipan Wen 2022Chinese Chemical Letters2022,33,3:1
