| 2 | Significant divergence of sex-related non-coding RNA expression patterns among closely related species in Drosophila显示文摘Whether or not non-coding RNA genes play a significant role in reproductive biology and evolution of sex determination systems is an important problem. We report identification of sex-related non-coding RNA (ncRNA) genes and an analysis of ncRNAs expression patterns among Drosophila species. We detected 12 candidate ncRNAs that are expressed in the gonads of D. melanogaster by an integrative approach of RT-PCR and computational analysis of sequence conservation across species. We ex-perimentally analyzed these ncRNA gene transcripts in head, ovary and testis of closely related species D. simulans, D. yakuba,D. pseudoobscura and D. virilis. We observed that the occurrence and extent of expression of most ncRNA fragments among closely related species show significant divergence. | YANG YongFei LI Zheng FAN QiChang LONG ManYuan ZHANG WenXia | 2007 | Chinese Science Bulletin2007，52，6： | 1 |
| 3 | Mg,Ti-base surface integrated layer and bulk doping to suppress lattice oxygen evolution of Ni-rich cathode material at a high cut-off voltage显示文摘The Nickel-rich layered cathode materials charged to 4.5 V can obtain a specific capacity of more than 200 m Ah g^(-1).However,the nickel-rich layered cathode materials suffer from the severe capacity fade during high-voltage cycling,which is related to the phase transformation and the surface sides reactions caused by the lattice oxygen evolution.Here,the simultaneous construction of a Mg,Ti-based surface integrated layer and bulk doping through Mg,Ti surface treatment could suppress the lattice oxygen evolution of Nirich material at deep charging.More importantly,Mg and Ti are co-doped into the particles surface to form an Mg_(2)TiO_(4) and Mg_(0.5–x)Ti_(2–y)(PO_(4))_(3) outer layer with Mg and Ti vacancies.In the constructed surface integrated layer,the reverse electric field in the Mg_(2)TiO_(4) effectively suppressed the outward migration of the lattice oxygen anions,while Mg_(0.5–x)Ti_(2–y)(PO_(4))_(3) outer layer with high electronic conductivity and good lithium ion conductor could effectively maintained the stability of the reaction interface during highvoltage cycling.Meanwhile,bulk Mg and Ti co-doping can mitigate the migration of Ni ions in the bulk to keep the stability of transition metal–oxygen(M-O)bond at deep charging.As a result,the NCM@MTP cathode shows excellent long cycle stability at high-voltage charging,which keep high capacity retention of 89.3%and 84.3%at 1 C after 200 and 100 cycles under room and elevated temperature of 25 and 55°C,respectively.This work provides new insights for manipulating the surface chemistry of electrode materials to suppress the lattice oxygen evolution at high charging voltage. | Fan Peng Youqi Chu Yu Li Qichang Pan Guangchang Yang Lixuan Zhang Sijiang Hu Fenghua Zheng Hongqiang Wang Qingyu Li | 2022 | Journal of Energy Chemistry2022，31，8： | 1 |
