Solid-state NMR for metal-containing zeolites: From active sites to reaction mechanism

Xingling Zhao, Jun Xu, Feng Deng

《化学科学与工程前沿（英文）》 2020年第14卷第2期页码 159-187 doi: 10.1007/s11705-019-1885-1

摘要： Metal-containing zeolite catalysts have found a wide range of applications in heterogeneous catalysis. To understand the nature of metal active sites and the reaction mechanism over such catalysts is of great importance for the establishment of structure-activity relationship. The advanced solid-state NMR (SSNMR) spectroscopy is robust in the study of zeolites and zeolite-catalyzed reactions. In this review, we summarize recent developments and applications of SSNMR for exploring the structure and property of active sites in metal-containing zeolites. Moreover, detailed information on host-guest interactions in the relevant zeolite catalysis obtained by SSNMR is also discussed. Finally, we highlight the mechanistic understanding of catalytic reactions on metal-containing zeolites based on the observation of key surface species and active intermediates.

Solubility of CO in solid-state PET measured by pressure-decay method

CHEN Miaocan, ZHAO Ling, LIU Tao, WU Jiangwei, YUAN Weikang

《化学科学与工程前沿（英文）》 2008年第2卷第2期页码 214-219 doi: 10.1007/s11705-008-0040-1

摘要： The solubility of CO in solid-state PET was measured using a pressure-decay method. In order to calculate the solubility of CO in the amorphous region of PET, the crystallinity of solid state PET dissolved in CO at different pressures and temperatures was measured by differential scanning calorimetry (DSC). The solubility increases with increasing pressure and it follows a linear relationship and obeys Henry’s law when the pressure is below 8 MPa. The effect of temperature on solubility is weak and the solubilities at different temperatures are almost the same under low pressures. At higher pressure, the solubility decreases with an increase in temperature. The solubility of CO in the amorphous region of PET at 373.15 K, 398.15 K and 423.15 K was correlated with the Sanchez-Lacombe equation of state with a maximal correlation error of 6.69%.

A fully solid-state cold thermal energy storage device for car seats using shape-memory alloys

《能源前沿（英文）》 2023年第17卷第4期页码 504-515 doi: 10.1007/s11708-022-0855-3

摘要： Thermal energy storage has been a pivotal technology to fill the gap between energy demands and energy supplies. As a solid-solid phase change material, shape-memory alloys (SMAs) have the inherent advantages of leakage free, no encapsulation, negligible volume variation, as well as superior energy storage properties such as high thermal conductivity (compared with ice and paraffin) and volumetric energy density, making them excellent thermal energy storage materials. Considering these characteristics, the design of the shape-memory alloy based the cold thermal energy storage system for precooling car seat application is introduced in this paper based on the proposed shape-memory alloy-based cold thermal energy storage cycle. The simulation results show that the minimum temperature of the metal boss under the seat reaches 26.2 °C at 9.85 s, which is reduced by 9.8 °C, and the energy storage efficiency of the device is 66%. The influence of initial temperature, elastocaloric materials, and the shape-memory alloy geometry scheme on the performance of car seat cold thermal energy storage devices is also discussed. Since SMAs are both solid-state refrigerants and thermal energy storage materials, hopefully the proposed concept can promote the development of more promising shape-memory alloy-based cold and hot thermal energy storage devices.

Study on microbial protein and the mechanism of solid-state fermentation with periodical dynamic changes

FU Xiaoguo, CHEN Hongzhang, LI Hongqiang, MA Runyu

《化学科学与工程前沿（英文）》 2007年第1卷第2期页码 113-117 doi: 10.1007/s11705-007-0021-9

摘要： The effect of different extraction and purification conditions on the microbial protein obtained from solid-state fermentation (SSF) and the effect of periodical dynamic changes of air on protein have been studied. The mechanism of solid-state fermentation with periodical dynamic changes of air is also discussed. Compared with static solid-state fermentation, periodical dynamic changes of air afford a higher protein mass; from 1 g of the fermentation microbe, 5.3 mg of the intracellular protein (an increase of 34.63%) and 9.09 mg of the extracellular protein (an increase of 17.8%) were obtained on the sixth day of fermentation. The filter paper activity and carboxymethyl cellulose activity (FPA and CMCase) of the extracellular protein are 1.739 μmol/s and 109.592 μmol/s, respectively, which represent increases of 60.1% and 21.2% over the corresponding values for static solid-state fermentation. The FPA and CMCase of the intracellular protein are 0.245 μmol/s and 6.392 μmol/s, respectively, which represent decreases of 22.2% and 38.7% over the corresponding values for static solid-state fermentation. The enzyme activity of the microbial extracellular protein in solid-state fermentation with periodical dynamic changes of air on the fifth day is nearly equal to that on the sixth day without periodical dynamic changes of air, so the period of fermentation can be shortened. The sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) experiments suggest that pulsating air pressure stimulation leads to a decrease in the amount of protein component with molecule mass of about 80400Da, and an increase in the amount of protein component with molecule mass of about 28520Da.

High performance solid-state thermoelectric energy conversion via inorganic metal halide perovskites

Lifu YAN, Lingling ZHAO, Guiting YANG, Shichao LIU, Yang LIU, Shangchao LIN

《能源前沿（英文）》 2022年第16卷第4期页码 581-594 doi: 10.1007/s11708-022-0831-y

摘要： Solid-state thermoelectric energy conversion devices attract broad research interests because of their great promises in waste heat recycling, space power generation, deep water power generation, and temperature control, but the search for essential thermoelectric materials with high performance still remains a great challenge. As an emerging low cost, solution-processed thermoelectric material, inorganic metal halide perovskites CsPb(I_1–xBr_x)₃ under mechanical deformation is systematically investigated using the first-principle calculations and the Boltzmann transport theory. It is demonstrated that halogen mixing and mechanical deformation are efficient methods to tailor electronic structures and charge transport properties in CsPb(I_1–xBr_x)₃ synergistically. Halogen mixing leads to band splitting and anisotropic charge transport due to symmetry-breaking-induced intrinsic strains. Such band splitting reconstructs the band edge and can decrease the charge carrier effective mass, leading to excellent charge transport properties. Mechanical deformation can further push the orbital energies apart from each other in a more controllable manner, surpassing the impact from intrinsic strains. Both anisotropic charge transport properties andZT values are sensitive to the direction and magnitude of strain, showing a wide range of variation from 20% to 400% (with a ZT value of up to 1.85) compared with unstrained cases. The power generation efficiency of the thermoelectric device can reach as high as approximately 12% using mixed halide perovskites under tailored mechanical deformation when the heat-source is at 500 K and the cold side is maintained at 300 K, surpassing the performance of many existing bulk thermoelectric materials.

Nickel nanopore arrays as promising current collectors for constructing solid-state supercapacitors with

Huaping Zhao, Long Liu, Yaoguo Fang, Ranjith Vellacheri, Yong Lei

《化学科学与工程前沿（英文）》 2018年第12卷第3期页码 339-345 doi: 10.1007/s11705-018-1699-6

摘要：

In this work, nickel nanopore arrays with a highly-oriented nanoporous structure inherited from porous alumina membranes were used as nanostructured current collectors for constructing ultrahigh rate solid-state supercapacitors. A thin layer of poly(3,4-ethylenedioxythiophene) (PEDOT) as electroactive materials was conformally coated onto nickel nanopores to form heterostructured electrodes. The as-prepared electrodes have a large specific surface area to ensure a high capacity, and the highly-oriented nanoporous structure of nickel nanopores reduces the ion transport resistance, allowing the ions in the solid-state electrolytes to quickly access the PEDOT surface during the fast charge-discharge process. As a result, the assembled solid-state supercapacitor in a symmetric configuration exhibits an ideal capacitive behavior and a superior rate capability even at an ultrahigh scan rate of 50 V·s⁻¹.

Photoluminescent properties of Sb

Fushan WEN, Lingling SUN, Jinhyeok KIM

《化学科学与工程前沿（英文）》 2011年第5卷第4期页码 429-434 doi: 10.1007/s11705-011-1138-4

摘要： Sb -doped YBO crystals were prepared through a low-temperature hydrothermal method and a high-temperature solid-state technique, respectively. The effects of preparation methods on the morphologies and luminescent properties of YBO phosphors were investigated. The YBO crystals from the hydrothermal system look like flowers, whereas those from the solid-state process look like some agglomerates of little spheres. The Sb -doped YBO powders prepared via both methods showed the blue emission with the peak at around 452 nm, which corresponds to the P → S transition of Sb ions. However, the emission intensity of the Sb -doped YBO from the hydrothermal system is about 3.5 times as much as that from the solid-state process. The (Sb ,Eu ) co-doped YBO crystals were also prepared through the two methods. The results showed that the emission intensity of Sb ions in (Sb , Eu ) co-doped YBO synthesized by the hydrothermal method is stronger than that by the solid-state process.

摘要：

固体电解质的低离子电导率及固体电解质与固态电极之间较差的界面可靠性是阻碍固态钠电池（SSSB）应用的两大紧迫挑战。本文采用简单的两步固相法合成了名义成分为Na_3+2xZr_2‒xMg_xSi₂PO₁₂ 的钠（Na）超离子导体（NASICON）型固体电解质，其中在25 ℃时Na_3.3Zr_1.85Mg_0.15Si₂PO₁₂（x=0.15, NZSP-Mg_0.15)表现出了3.54 mS∙cm^‒1的最高离子电导率。通过深入研究，本文证实晶界成分在决定NASICON总离子电导率中起着至关重要的作用。此外，由于文献中缺乏关于NASICON是否能够提供足够的阳极电化学稳定性来实现高压固态钠电池的研究，我们首先使用了高压Na₃(VOPO₄)₂F (NVOPF)正极来验证其与优化后的NZSP-Mg_0.15固体电解质之间的兼容性。通过比较不同配置（低压阴极与高压阴极、液态电解质与固体电解质）电池的电化学性能，以及对循环后的NZSP-Mg_0.15进行X射线光电子能谱（XPS）评估，结果表明，NASICON固体电解质在高电压下不够稳定，这证明了研究NASICON固体电解质和高压阴极之间界面的重要性。此外，通过将NZSP-Mg_0.15 NASICON 粉末涂在聚乙烯（PE）隔膜（PE@NASICON）上，形成了2.42 A∙h 的碳|PE@NASICON|NaNi_2/9Cu_1/9Fe_1/3Mn_1/3O₂ 非水系钠离子电池，其具有出色的循环性能，在2000 周循环后容量保持率为88%，从而证明涂有NASICON型固体电解质的隔膜具有高可靠性。

摘要：

A new type of traction drive system consisting of solid-state traction transformer (SSTT), inverter unit, auxiliary inverter, traction motor and other key components is built in order to suit the demand of developing the next-generation electric traction system which will be efficient and lightweight, with high power density. For the purpose of reducing system volume and weight and improving efficiency and grid-side power quality, an efficient SSTT optimized topology combining high-voltage cascaded rectifiers with high-power high-frequency LLC resonant converter is proposed. On this basis, an integrated control strategy built upon synchronous rotating reference frame is presented to achieve unified control over fundamental active, reactive and harmonic components. The carrier-interleaving phase shift modulation strategy is proposed to improve the harmonic performance of cascaded rectifiers. In view of the secondary pulsating existing in a single-phase system, the mathematical model of secondary power transfer is built, and the mechanism of pulsating voltage resulting in beat frequency of LLC resonant converter is revealed, so as to design optimum matching of system parameters. Simulation and experimental results have verified that the traction system and control scheme mentioned in this paper are reasonable and superior and that they meet the future application requirements for rail transit.
