Bioprocess inspired formation of calcite mesocrystals by cation-mediated particle attachment mechanism

National Science Review 2023年第4期10卷 159-168页

Calcite mesocrystals were proposed, and have been widely reported, to form in the presence of polymer additives via oriented assembly of nanoparticles. However, the formation mechanism and the role of polymer additives remain elusive. Here, inspired by the biomineralization process of sea urchin spine comprising magnesium calcite mesocrystals, we show that calcite mesocrystals could also be obtained via atachment of amorphous calcium carbonate(ACC) nanoparticles in the presence of inorganic zinc ***, we demonstrate that zinc ions can induce the formation of temporarily stabilized amorphous nanoparticles of less than 20 nm at a significantly lower calcium carbonate concentration as compared to pure solution, which is energetically beneficial for the atachment and occlusion during calcite growth. The cation-mediated particle atachment crystallization significantly improves our understanding of mesocrystal formation mechanisms in biomineralization and offers new opportunities to bioprocess inspired inorganic ions regulated materials fabrication.

Aqueous zinc batteries offer significant potential for large-scale energy storage, wearable devices, and medium-to low-speed transportation due to their safety, affordability, and environmental friendliness. However, the uneven zinc deposition at the anode side caused by localized reaction activity from the passivation layer presents challenges that significantly impact the battery's stability and lifespan. In this study, we have proposed an expandable and maneuverable gel sustained-release (GSR) treatment to polish the Zn metal, which in situ converts its native passivation layer into a composite interphase layer with nanocrystal zinc phosphate and flexible polyvinyl alcohol. Such a thin and uniform interface contributes to fast and homogeneous Zn ion transport and improved anti-corrosion ability, enabling uniform zinc deposition without dendrite growth and thereby improving the battery performance with high-rate ability and long cycle life. This GSR treatment method, characterized by its simplicity, low cost, and universality, facilitates the widespread application of aqueous zinc batteries. © 2025 Institute of Process Engineering, Chinese Academy of Sciences

Chirality is a unique phenomenon in nature. Chiral interactions play an important role in biological and physiological process- es, which provides much inspiration for scientists to develop cbiral materials. As a breakthrough from traditional materials, bi- ointerface materials based on chiral polymers have attracted increasing interest over the past few years. Such materials ele- gantly combine the advantages of chiral surfaces and traditional polymers, and provide a novel solution not only for the inves- tigation of chiral interaction mechanisms but also for the design of biomaterials with diverse applications, such as in tissue en- gineering and biocompatible materials, bioregulation, chiral separation and chiral sensors. Herein, we summarize recent ad- vances in the study of chiral effects and applications of chiral polymer-based biointerface materials, and also present some challenges and perspectives.

Alumina Ceramics Fabricated by in-situ Consolidation of Pre-gelling Starch

引用

Journal of Wuhan University of technology(materials Science) 2018年第3期33卷 758-766页

作者：朱田丽王友法 State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology

An in-situ consolidation method was developed and optimized to successfully fabricate alumina ceramics using pre-gelling starch. Our results showed that the obtained ceramics have more homogeneous microstructure, higher density, higher flexural strength, and favorable biocompatibility compared to the regular one. During the process, cornstarch granules swelled and deformed but no fracture was observed. After the cornstarch granules bursted, alumina particles were suspended uniformly in the three-dimensional network structure to generate a much smoother surface. Below 0.5 wt% higher cornstarch content increased the flexural strength of prepared ceramics, while above 0.5 wt% the mechanical properties were compromised. Therefore the cornstarch content of 0.5% was the optimal concentration to achieve the highest mechanical strength of the prepared ceramics, with a measured flexural strength of 341 MPa, and a relative density of 96.01%.

Journal of Wuhan University of technology(materials Science) 2019年第5期34卷 1220-1227页

作者： WU Jiansheng XIAO Shengqiang State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology

Two novel non-fullerene small molecule acceptors were prepared with the conjugated backbone of 5 H-fluoreno[3, 2-b:6, 7-b’] dithiophene carrying the electron deficient unit of dicyanomethylene indanone(DICTFDT) and rhodanine(TFDTBR), respectively. The two acceptors exhibited excellent thermal stability and strong absorption in the visible region. The LUMO level is estimated to be at-3.89 eV for DICTFDT and-3.77 eV for TFDTBR. When utilized as the acceptor in bulk heterojunction polymer solar cells with the polymer donor of PBT7-Th, the optimized maximum power conversion efficiency of 5.12% and 3.95% was obtained for the device with DICTFDT and TFDTBR, respectively. The research demonstrates that 5 H-fluoreno[3, 2-b:6, 7-b’] dithiophene can be an appealing candidate for constructing small molecular electron acceptor towards efficient polymer:non-fullerene bulk heterojunction solar cells.

Energy Storage materials 2025年 77卷

作者： Li, Yang Wu, Gang Fan, Xiaomeng Li, Dabing Liu, Hong Zhao, Xiaoxue Ren, Wanqing Lei, Peng Zhao, Xianyi Wang, Xun Wang, Guoxu Gao, Lei Nan, Ce-Wen Fan, Li-Zhen Institute for Advanced Materials and Technology University of Science and Technology Beijing Beijing 100083 China School of Materials Science and Engineering Guilin University of Technology Guilin541004 China State Key Laboratory of New Ceramics and Fine Processing School of Materials Science and Engineering Tsinghua University Beijing 100084 China School of Chemistry and Chemical Engineering Heze University Heze274015 China

Solid-state electrolytes (SSEs) play a crucial role in the operation of all-solid-state lithium metal batteries (ASSLMBs). Among them, sulfide SSEs have attracted particular attention due to their high ionic conductivity. However, the incompatibility of sulfide SSEs with lithium anodes and the inherent air instability severely impact battery cycling performance. Here, we successfully synthesize halogen-rich lithium argyrodites with the general formula Li5.5+3xP1−xCuxS4.5Cl1.5−2xBr2x. The incorporation of Cu and Br alter the spatial arrangement and electronic distribution of structure. Given that the anion disorder positively affects Li-ion dynamics, the ultrahigh ionic conductivity of 10.3 mS cm−1 at room temperature has been achieved in Li5.8P0.9Cu0.1S4.5Cl1.3Br0.2 (LPSC-CB). Importantly, benefiting from the robust and stable interlayer, the lithium symmetric batteries deliver prolonged plating/stripping over 3000 h at 0.2 mA cm−2. Furthermore, the density functional theory calculations were used to prove the mechanisms of high chemical stability. Notably, the LPSC-CB electrolyte has remarkable applicability in ASSLMBs. The full batteries of FeS2/LPSC-CB/Li deliver outstanding discharge-specific capacities of 788.9 mAh g−1 and robust cycling stability (>4.02 mAh cm−2 after 200 cycles). The versatile CuBr2 substitution in the most promising argyrodite electrolytes is considered as a valid strategy to realize high ionic conductivity and air-stabilized sulfide SSEs for large-scale applications. © 2025 Elsevier B.V.

With the growing scale of the lithium-ion battery market, the number of retired lithium-ion batteries (LIBs) increase exponentially. The recycling of spent LIBs not only reduces environmental pressure but also achieves resource recycling, making the necessity of recycling indispensable. Wherein the separation of cathode active materials from current collectors is a key step in the recycling process of spent LIBs, which directly affects the recycling efficiency and the reuse value of materials. Moreover, by recycling spent LIBs and extracting valuable metals from them, it is possible to alleviate the shortage of resources and realize the sustainable economic development. Among cathode materials, layered lithium nickel cobalt manganese oxide (NCM) has the highest recycling value as it contains more valuable metals such as lithium (Li), nickel (Ni), cobalt (Co) and manganese (Mn). Therefore, in this review we mainly summarize and analyze the latest research progress in the field of NCM cathode material separating from aluminum (Al) foil by focusing on its methods, principles, advantages and limitations. Also, it provides solutions to existing challenges, which have important reference significance to promote the sustainable recycling and use of spent LIBs. © 2025 Elsevier Ltd
