| 1 | Review of preferentially selective lithium extraction from spent lithium batteries: Principle and performance显示文摘Lithium,as the lightest and lowest potential metal,is an ideal 'battery metal' and the core strategic metal of the new energy industry revolution.Recovering lithium from spent lithium batteries(LIBs)has become one of the significant approaches to obtaining lithium resources.At present,the lithium extraction being generally placed at the last step of the spent LIBs recovery process has puzzles such as high acid consumption,low Li recovery purity and low recovery efficiency.Selective lithium extraction at the first step of the recovery process can effectively solve those puzzles.Since lithium leaching is a non-spontaneous reaction requiring additional energy to achieve,it is found that these methods can be divided into five ways according to the different types of energy driving the reaction occurring:(ⅰ)electric energy driving lithium extraction;(ⅱ) chemical energy driving lithium extraction;(ⅲ) mechanical energy driving lithium extraction;(ⅳ) thermal energy driving lithium extraction;(ⅴ) other energy driving lithium extraction.Through the analysis of the principle,reaction process and results of recovering lithium methods can provide a few directions for scholars’ subsequent research.It is necessary to speed up the exploration of the principle of these methods.It is expected that this study could provide a reference for the research on the selective lithium extraction. | Zhe Gao Meiting Huang Liming Yang Yufa Feng Yuan Ding Penghui Shao Xubiao Luo | 2023 | Journal of Energy Chemistry2023，，3： | 1 |
| 2 | TWO TYPES OF MONOAMINE OXIDASE IN RAT BRAIN显示文摘Monoamine oxidase(MAO) embedded in the outer mitochondrial membrane oxidatively deaminates amine transmitters in the nervous system. MAO are divided into two types, Type A and Type B, according to their substrate specificity and their sensitive inhibitors. Type A activity preferentially deaminates 5-hydroxytamine (5-HT) and is sensitive to | 蔡惠罗 | 1987 | Chinese Science Bulletin1987，32，9： | 0 |
| 3 | m^(6)A-modified RNAs possess distinct poly(A)tails显示文摘N^(6)-methyladenosine(m^(6)A)has been found to be the most common type of post-transcriptional chemical modification in mammalian mRNAs and long non-coding RNAs(lncRNAs)(Dominissini et al.,2012;Meyer et al.,2012).In both mammals and yeast,RNA m^(6)A preferentially occurs in both gene coding regions and 3’untranslated regions(3’-UTRs),implicating its fundamental roles in every aspect of post-transcriptional regulation,including splicing,stability,and translation(Wang et al.,2014,2015;Zhao et al.,2014;Yang et al.,2018b). | Shuang Wu Yiwei Zhang Lan Yao Jiaqiang Wang Falong Lu Yusheng Liu | 2023 | Journal of Genetics and Genomics2023，50，3： | 0 |
| 4 | STUDY ON β-FORM POLYPROPYLENE显示文摘Isotactic polypropylene is capable of crystallizing in several forms. The α or monoclinie form is the most stable and prevalent form. A γ or triclinic modification exists, which is generally associated with high pressure crystallization. A third crystalline modification, the β or hexagonal form, is occasionally found in commercial polypropylene, usually at low levels. Work by H. J. Leugering has shown that small amounts of a quinacridone colorant, permanent red E3B, preferentially nucleated | 史观一 张景云 | 1982 | Chinese Science Bulletin1982，27，3： | 0 |
| 5 | A NEW CONVENIENT METHOD FOR THE SYNTHESIS OF PERFLUOROALKYL 2H-PYRROLE显示文摘The reaction between 2,5-Dimethylpyrrole (1) and RFI (2)(RF: a, Cl(CF2)4; b, Cl(CF2)6; c, Cl(CF2)8; d, n-C6F13; e, n-C8F17) in the presence of Na2S2O4-NaHCO3 in acetonitrile resulted in the formation of 2-perfluoroalkyl-2,5-dimethyl-2H-pyrrole (3) as a major product in good yield. | Wei Yuan HUANG Wu Ping MA Shanghai Institute of Organic Chemistry, The Chinese Academy of Sciences, 345 Lingling Lu, Shanghai, 200032. | 1991 | Chinese Chemical Letters1991，2，10： | 0 |
| 6 | ANGULAR DISTRIBUTIONS FOR ^(13)C(K^-,π^-)_Λ^(13)C REACTIONS显示文摘The study of hypernuclear states produced in (K-, π-) reactions on nuclei has obtained valuable information on the A-nucleus system and has attracted much interest. Recently, the excitation spectra of A13C have been measured for the first time in the experiments at BNL. Different hypernuclear states are excited preferentially | 李扬国 姜焕清 王潍潍 | 1983 | Chinese Science Bulletin1983，28，4： | 0 |
| 7 | THE EFFECT OF db-cAMP ON THE GENE EXPRESSION OF CALMODULIN AND CYTOSKELETON IN THE TRANSFORMED CELLS显示文摘We have demonstrated that the distribution of microtubules (MT), mlcrofilaments (MF) and fibronectin (FN) were diminished, while the gene expression of the calmodulin and c- fos enhanced in the transformed C3H10T1/2 cells. After treatment with 1 mM db-cAMP for 1 hour and 2 hours, there was an early and repldly reduced in gene expression of Calmodulin and c-fos respectively. After db-cAMP treatment for 4 -5 days, the number of capping cells of ConA binding decreased significantly and the cell surface microvllll decreased as well. The growth of treated cells was inhibited markedly. By using 4F1 cDNA probe, which is preferentially expressed In G1 phase, we have found that the db- cAMP treated cells were accumulated at G1 phase. Of particular interest is the fact that the distribution of microtubules, mlcrofilaments and fibronectln were recovered after treatment with 1 mM db-cAMP for 6 days. It is suggested that the Inhibition of proliferation, alteration, of phenotype and reco- very of cytoskeleton is | 柳惠图 王端顺 张鸿卿 薛绍白 游劲松 杜春英 王晓良 | 1992 | Chinese Journal of Cancer Research1992，4，1： | 0 |

| 9 | Heating of multi-species upflowing ion beams observed by Cluster on March 28, 2001显示文摘Cluster satellites observed three successive outflowing ion beams on 28 March, 2001. It is generally accepted that these ion beams, composed of H^+, He^+, and O^+ ions, with three inverted-V structures in their energy spectra, are produced by acceleration through U-shaped potential structures. By eliminating the background ion population and employing Maxwelling fitting, we find that ions coming from the center of the potential structure have higher temperature than those from the flanks. Higher temperature of O^+ and He+compared to that of H^+ indicates that heavy ions are preferentially heated; we further infer that the heating efficiencies of O^+ and He^+ ions differ between the center and edges of the U-shaped potential structures. Estimation based on pitch angle observations shows that heating may also occur at an altitude above the upper boundary of the auroral acceleration region(AAR), where these beams are generally thought to be formed. | FangBo Yu SuiYan Fu WeiJie Sun XuZhi Zhou Lun Xie Han Liu Duo Zhao ShaoJie Zhao Li Li JingWen Zhang Tong Wu Ying Xiong | 2019 | Earth and Planetary Physics2019，3，3： | 0 |
