Fragility under shocking: molecular dynamics insights into defect evolutions in tungsten latticeSpringer Science and Business Media LLC - Tập 3 - Trang 234-242 - 2021
Peng-Jie Wang, Qiang Cao, Sheng Liu, Qing Peng
Tungsten has promising applications in high-radiation, high-erosion and
high-impact environments. Laser peening is an effective method to enhance the
surface mechanical properties of tungsten materials. However, the ultrafast
dynamic mechanism of defect evolutions induced by laser shockwave in tungsten
lattice is unclear. Here, we investigated the evolutions and interactions of
various defects und... hiện toàn bộ
Kết hợp cặp acid–base dựa trên polyoxometalat vào MIL-101 sulfonat nhằm đạt được vật liệu dẫn proton với độ dẫn proton cao và độ ổn định cao Dịch bởi AI Springer Science and Business Media LLC - Tập 4 - Trang 130-137 - 2021

Assembly of selenoniobate–vanadoniobate double-anion heteropolyoxoniobate: synthesis, structure, and magnetic propertySpringer Science and Business Media LLC - Tập 5 - Trang 75-80 - 2022
Zhi-Jie Liang, Nan Li, Hai-Bing Cheng, Wei-Xin Du, Guan Wang, Dong-Di Zhang
Recently, continuous interests and persisting efforts on heteropolyniobate have
been dedicated to its preparation and exploration. In this work, a novel
Se-centred heteropolyniobate,
[H2SeNb12(VO)4O40][Cu(en)2]2{[VNb12(VO)4O40][Cu(en)2]4}0.5·39H2O
(en = ethanediamine), was synthesized. The compound was synthesized in aqueous
solution by reacting the K7HNb6O19·13H2O with a mixture of vanadate (V) a... hiện toàn bộ
Recent research progress on mixed valence state tungsten based materialsSpringer Science and Business Media LLC - Tập 1 - Trang 5-18 - 2019
Shu Yin, Yusuke Asakura
Synthesis and characterization of tungsten based mixed valence state
nanoparticles and their novel applications are reviewed. The mixed valence state
tungsten based homogeneous nanomaterials such as bronze structure MxWO3
(M = Na+, K+, Rb+, Cs+, NH4+, etc.) and tungsten sub-oxide W18O49 possess
excellent infrared (IR) light shielding property, implying their great potential
applications on heat ra... hiện toàn bộ
Tungsten-based photocatalysts with UV–Vis–NIR photocatalytic capacity: progress and opportunitySpringer Science and Business Media LLC - Tập 1 - Trang 247-257 - 2020
Yuhua Wang, Tongyao Liu, Huihui Li, Bin Liu, Linfen Yang
Semiconductor photocatalysis is proven to be one of the potential approaches to
solve energy crisis and environmental problems. Efficient solar energy
utilization and superior charge carrier separation capacity are two crucial
aspects in photocatalysis. Herein, the photocatalytic performances of the
pristine and modified tungsten-based materials with mixed valence state are
summarized concisely. T... hiện toàn bộ
H-bonding interactions enable a 3D pillared cobalt (II) coordination polymer for touchless finger moisture detectionSpringer Science and Business Media LLC - Tập 5 - Trang 109-117 - 2022
Hao Dong, Le-Xi Zhang, Heng Xu, Yan-Yan Yin, Xing-Bai Zhao, Li-Jian Bie
Coordination polymers (CPs) are emerging as the next generation of macromolecule
materials in many industrial and technological applications, e. g. gas/humidity
sensing. The design of CP-based sensors with high performance and low cost is of
significance, but this work is still in the infancy stage. In this contribution,
a new one dimensional (1D) CP has been successfully synthesized by a simple

Towards superior lithium–sulfur batteries with metal–organic frameworks and their derivativesSpringer Science and Business Media LLC - Tập 4 - Trang 269-283 - 2022
Ning Yuan, Yi-Rui Deng, Shan-Hu Wang, Li Gao, Jin-Lin Yang, Na-Chuan Zou, Bing-Xin Liu, Jun-Qing Zhang, Rui-Ping Liu, Lei Zhang
Lithium–sulfur batteries (LSBs) are one of the most promising energy storage
devices in the future due to their high theoretical specific capacity
(1675 mA·h·g–1) and energy density (2600 W·h·kg–1). However, the severe capacity
decay caused by the shuttle effect of polysulfides needs to be addressed before
the practical application. Metal–organic frameworks (MOFs) and their derivatives
are known f... hiện toàn bộ
