The calcium aluminosilicate-based glasses(CaO-Al_(2)O_(3)-SiO_(2),CAS)with different Fe_(2)O_(3)content(0.10wt%,0.50wt%,0.90wt%,and 1.30wt%)were prepared by traditional melt-quenching *** glass network structure,thermal and mechanical properties,and crystallization behavior changes were investigated by nuclear magnetic resonance spectrometer,Fourier-transform infrared spectro-photometer,X-ray diffractometer,differential scanning calorimetry and field emission scanning electron microscope *** change of Q^(n)in glass structures reveals the glass network connectivity decreases due to the increasing content of Fe_(2)O_(3)addition,resulting in the increasing of non-bridging number in glass *** glass densities slightly rise from 2.644 to 2.681 g/cm^(3),while Vickers’s hardness increases at first,from 6.469 to 6.901 GPa,then slightly drops to 6.745 GPa,with Fe_(2)O_(3)content *** is almost no thermal expansion coefficient change from different Fe_(2)O_(3)*** glass transmittance in visible range gradually decreases with higher Fe_(2)O_(3)content,resulting from the strong absorption of Fe^(2+)and Fe^(3+)*** calculated activation energy from thermal analysis results first decreases from 282.70 to 231.18 kJ/mol,and then increases to 244.02 kJ/mol,with the Fe_(2)O_(3)content increasing from 0.10wt%to 1.30wt%.Meanwhile,the maximum Avrami constant of 2.33 means the CAS glasses exhibit two-dimensional *** of the CAS glass-ceramics samples contain main crystal phase of anorthite,the microstructure appears lamellar and columnar crystals.

Selection of Negative Charged Acidic Polar Additives to Regulate Electric Double Layer for Stable Zinc Ion Battery

引用

Nano-Micro Letters 2024年第12期 350-364页

作者： Xing Fan lina chen Yongjing Wang Xieyu Xu Xingxing Jiao Peng Zhou Yangyang Liu Zhongxiao Song Jiang Zhou State Key Laboratory for Mechanical Behavior of Materials Xi'an Jiaotong University School of Materials Science and Engineering Harbin Institute of Technology (Shenzhen) Research Institute of Frontier Science Southwest Jiaotong University Hunan Provincial Key Defense Laboratory of High Temperature Wear-Resisting Materials and Preparation Technology Hunan University of Science and Technology School of Instrument Science and Technology Xi'an Jiaotong University School of Materials Science and Engineering Hunan Provincial Key Laboratory of Electronic Packaging and Advanced Functional Materials Central South University

Zinc-ion batteries are promising for large-scale electrochemical energy storage systems, which still suffer from interfacial issues, e.g., hydrogen evolution side reaction（HER）, self-corrosion, and uncontrollable dendritic Zn electrodeposition. Although the regulation of electric double layer（EDL） has been verified for interfacial issues, the principle to select the additive as the regulator is still misted. Here, several typical amino acids with different characteristics were examined to reveal the interfacial behaviors in regulated EDL on the Zn anode. Negative charged acidic polarity（NCAP） has been unveiled as the guideline for selecting additive to reconstruct EDL with an inner zincophilic H2O-poor layer and to replace H2O molecules of hydrated Zn2+with NCAP glutamate. Taking the synergistic effects of EDL regulation, the uncontrollable interface is significantly stabilized from the suppressed HER and anti-self-corrosion with uniform electrodeposition. Consequently, by adding NCAP glutamate, a high average Coulombic efficiency of 99.83% of Zn metal is achieved in Zn|Cu asymmetrical cell for over 2000 cycles, and NH4V4O10|Zn full cell exhibits a high-capacity retention of 82.1% after 3000 cycles at 2 A g-1. Recapitulating, the NCAP principle posted here can quicken the design of trailblazing electrolyte additives for aqueous Zn-based electrochemical energy storage systems.

对数据产权给予恰当的权利定位,有助于让数据成为创造和捕获价值的新经济资源。数据的价值在于使用,而传统数据产权模式在促进数据流动、体现公平分配、保障数据安全等方面存在局限,依循既有的概念术语和体系结构难以实现数据价值化的经济过程,立法规则的留白处理也导致学界对数据产权的理论界定逻辑和实施路径莫衷一是。数字经济的发展需要现有法律对新问题作出规范化解释。根据数据资源作为新型生产要素的特性,数据资源持有权、数据加工使用权、数据产品经营权“三权分置”的数据产权制度框架被创造性提出,这摆脱了“权属决定流转”的桎梏。“三权分置”围绕数据价值形成和实现的过程建立了结构性产权分置制度,这与数据产业链的运行逻辑一脉相承;三权之间的结构性关系建构于数据全生命周期的流转状态,因而更利于满足多元主体对高质量可再利用数据要素的需求。但“三权分置”数据产权制度采用的“产权”概念完全不同于传统的财产权或产权概念,它的法理正当性、立法可行性等问题仍需详加讨论和细致分析。“三权分置”产权制度的理论逻辑可以从两阶层、内外部的立体结构体系加以理解,明晰该制度的基本问题将对我国数据产权制度体系的深入研究有较大助益。
