| 1 | Enrichment of putative human epidermal stem cells based on cell size and collagen type IV adhesiveness显示文摘人的表皮的干细胞(EpSCs ) 的丰富和鉴定具有为基本研究和临床的申请的首要的重要性。尽管为 EpSCs 的丰富的几条途径被建立了,充实可行 EpSCs 的一张纯人口仍然是一项挑战性的任务。一条改进途径值得发展提高 EpSCs 的纯净和生存能力。这里,我们报导那种房间尺寸与骨胶原类型 IV 粘着性结合了能在一条改进途径被使用充实纯、可行的人的 EpSCs。我们分开了很快支持者 keratinocytes 进从 5-7 microm (人口 A )在尺寸 的三张人口到 7-9 microm (人口 B ),到>或在直径的 =9 microm (人口 C ),并且发现人的通常认为的 EpSCs 能进一步与最小的尺寸在人口 A 被充实。在三张人口之中,人口 A 显示了 beta1-integrin 受体的最高的密度,在 G0/G1 阶段包含了房间的最高的百分比,显示出最高的原子核到细胞质比率,并且拥有了最高的殖民地形成效率(CFE ) 。当注入了鼠科的胚囊时,这些房间参予了多织物形成。与根据 beta1-integrin 抗体染色排序通常认为的 EpSCs 的一条以前的途径相比,更显著地, EpSCs 的生存能力由改进途径充实显著地被提高。我们的结果为人的 EpSCs 的丰富提供通常认为的策略,并且在干细胞生物学鼓励进一步的学习进房间尺寸的角色。 | Juxue Li Chenglin Miao Welxiang Guo Liwei Jia Jiaxi Zhou Baohua Ma Sha Peng Shuang Liu Yujing Cao Enkui Duan | 2008 | Cell Research2008，18，3： | 8 |
| 2 | Recent Advances in Constructing Interfacial Active Catalysts Based on Layered Double Hydroxides and Their Catalytic Mechanisms显示文摘The interaction between the metal and the support of supported metal catalysts, which are widely used in industry, is the primary focus of the study of such catalysts. With the developing understanding of the metal–support interaction, the intrinsic factor that influences the catalytic performance has been determined to be the structure of interfacial sites. Layered double hydroxides(LDHs, a class of two-dimensional layered anion clay) possess several unique characteristics, such as the following:(1) tunable elemental component, homogeneous distribution of metal cations.(2) anchoring eff ect.(3) multiple layered structure for exfoliation or intercalation and special memory eff ect;and(4) internal/external confinement eff ects during topological transformation. Taking LDHs and their derivatives as precursors or supports shows superior advantages in designing interfacial active catalysts with tunable properties. Therefore, this review is mainly focused on constructing interfacial active catalysts by LDHs and revealing the interfacial eff ects(including electronic, geometric, and bifunctional eff ects) on the catalytic performance that will provide new perspectives and approaches for the development of heterogeneous catalysis. | Haoxuan Du Jiaxuan Fan Chenglin Miao Mingyu Gao Yanan Liu Dianqing Li Junting Feng | 2021 | Transactions of Tianjin University2021，27，1： | 1 |
| 3 | Acceptor-Donor-Acceptor π-Stacking Boosts Intramolecular Through-Space Charge Transfer towards Efficient Red TADF and High-PerformanceOLEDS显示文摘Organic push-pull systems featuring through-space charge transfer(TSCT)excited states have been disclosed to be capable of exhibiting thermally activated delayed fluorescence(TADF),but to realize high-efficiency long-wavelength emission still remains a challenge.Herein,we report a series of strongly emissive orange-red and red TSCT-TADF emitters having(quasi)planar and rigid donor and acceptor segments which are placed in close proximity and orientated in a cofacial manner.Emission maxima(λ_(em))of 594−599 nm with photoluminescence quantum yields(PLQYs)of up to 91%and delayed fluorescence lifetimes of down to 4.9μs have been achieved for new acceptor-donor-acceptor(A-D-A)molecules in doped thin films.The presence of multiple acceptors and the strong intramolecularπ-stacking interactions have been unveiled to be crucial for the efficient low-energy TSCT-TADF emissions.Organic light-emitting diodes(OLEDs)based on the new A-D-A emitters demonstrated electroluminescence with maximum external quantum efficiencies(EQEs)of up to 23.2%for the red TSCT-TADF emitters.An EQE of 18.9%at the brightness of 1000 cd m^(-2) represents one of the highest values for red TADF OLEDs.This work demonstrates a modular approach for developing high-performance red TADF emitters through engineering through-space interactions,and it may also provide implications to the design of TADF emitter with other colours. | Chenglin Jiang Jingsheng Miao Danwen Zhang Zhenhua Wen Chuluo Yang Kai Li | 2022 | Research2022，，4： | 0 |
| 4 | Interactive mechanisms between caveolin-1 and actin filaments or vimentin intermediate filaments instruct cell mechanosensing and migration显示文摘Introduction Cell mechanosensing is the process that cell senses extracellular mechanical cues through mechanosensors and transduces them to downstream signaling pathways to alter cell mechanics and behaviors,which is involved in embryonic development(Gaetani et al.,2020),tissue regeneration(Fu et al.,2019),inflammatory response(Worbs et al.,2017),and tumor invasion and metastasis(Gargalionis et al.,2018).This ability is crucial for cells to adapt to mechanical stimuli(compressive force,shear stress,substrate rigidity,topology,adhesiveness,etc.)and maintain homeostasis(Chen et al.,2017). | Daijiao Tang Yue Zhang Jie Mei Jing Zhao Chenglin Miao Yaming Jiu | 2022 | Journal of Molecular Cell Biology2022，14，11： | 0 |
| 5 | A facile finger-paint physical modification for bilateral electrode/electrolyte interface towards a stable aqueous Zn battery显示文摘Since the electrode/electrolyte interface(EEI)is the main redox center of electrochemical processes,proper manipulation of the EEI microenvironment is crucial to stabilize interfacial behaviors.Here,a finger-paint method is proposed to enable quick physical modification of glass-fiber separator without complicated chemical technology to modulate EEI of bilateral electrodes for aqueous zinc-ion batteries(ZIBs).An elaborate biochar derived from Aspergillus Niger is exploited as the modification agent of EEI,in which the multi-functional groups assist to accelerate Zn^(2+)desolvation and create a hydrophobic environment to homogenize the deposition behavior of Zn anode.Importantly,the finger-paint interface on separator can effectively protect cathodes from abnormal capacity fluctuation and/or rapid attenuation induced by H_(2)O molecular on the interface,which is demonstrated in modified MnO_(2),V_(2)O_(5),and KMn HCF-based cells.The as-proposed finger-paint method opens a new idea of bilateral interface engineering to facilitate the access to the practical application of the stable zinc electrochemistry. | Hang Yang Duo Chen Yicheng Tan Hao Xu Li Li Yiming Zhang Chenglin Miao Guangshe Li Wei Han | 2023 | Journal of Energy Chemistry2023，，6： | 0 |
