| 1 | Ag_(3)PO_(4) decorated black urchin-like defective TiO_(2) for rapid and long-term bacteria-killing under visible light显示文摘Both phototherapy via photocatalysts and physical puncture by artificial nanostructures are promising substitutes for antibiotics when treating drug-resistant bacterial infectious diseases.However,the photodynamic therapeutic efficacy of photocatalysts is seriously restricted by the rapid recombination of photogenerated electron-hole pairs.Meanwhile,the nanostructures of physical puncture are limited to two-dimensional(2D)platforms,and they cannot be fully used yet.Thus,this research developed a synergistic system of Ag_(3)PO_(4) nanoparticles(NPs),decorated with black urchin-like defective TiO_(2)(BU-TiO_(2-X)/Ag_(3)PO_(4)).These NPs had a decreased bandgap compared to BU-TiO_(2-X),and BU-TiO_(2)-X/Ag_(3)PO_(4)(3:1)exhibited the lowest bandgap and the highest separation efficiency for photogenerated electron-hole pairs.After combination with BU-TiO_(2-X),the photostability of Ag_(3)PO_(4) improved because the oxygen vacancy of BU-TiO_(2-X) retards the reduction of Ag^(+) in Ag_(3)PO_(4) into Ag^(0),thus reducing its toxicity.In addition,the nanospikes on the surface of BU-TiO_(2-X) can,from all directions,physically puncture bacterial cells,thus assisting the hybrid’s photodynamic therapeutic effects,alongside the small amount of Ag^(+) released from Ag_(3)PO_(4).This achieves synergy,endowing the hybrid with high antibacterial efficacy of 99.76±0.15%and 99.85±0.09%against Escherichia coli and Staphylococcus aureus,respectively,after light irradiation for 20 min followed by darkness for 12 h.It is anticipated that these findings may bring new insight for developing synergistic treatment strategies against bacterial infectious diseases or pathogenic bacterial polluted environments. | Yingde Xu Xiangmei Liu Yufeng Zheng Changyi Li Kelvin Wai Kwok Yeung Zhenduo Cui Yanqin Liang Zhaoyang Li Shengli Zhu Shuilin Wu | 2021 | Bioactive Materials2021，6，6： | 2 |

| 3 | Nd-Hf Isotopic Decoupling of the Silurian–Devonian Granitoids in the Chinese Altai: A Consequence of Crustal Recycling of the Ordovician Accretionary Wedge?显示文摘Voluminous Silurian–Devonian granitoids intruded a greywacke-dominated Ordovician accretionary wedge in the Chinese Altai. These granitoids are characterized by significant Nd-Hf isotopic decoupling, the underlying mechanism of which, so far, has been poorly understood. This issue is addressed in this study by the integration of our new and regional published geological and geochemical data. Geological studies indicated a close spatial relationship between the regional anatexis of the Ordovician wedge and the formation of the granitoids, which is characterized by a gradual textural evolution from the partial molten Ordovician wedge sedimentary rocks(the Habahe Group) to the granitoid bodies. Compositionally, these granitoids and the Ordovician Habahe Group rocks displayed close geochemical similarities, in the form of arclike trace elemental signatures as well as comparable Nd isotopic characteristics. Combined with regional available data, we suggest that the Silurian–Devonian granitoids originated from the immature and chemically primitive Habahe Group rocks. Since Nd and Hf isotopic data for the Habahe Group rocks show significant Nd-Hf isotopic decoupling, we propose that the Silurian–Devonian granitoids inherited the Nd and Hf isotopic signatures from their sources, i.e., the Habahe Group rocks. In other words, the Nd-Hf decoupling in the Habahe Group rocks is the primary causative factor leading to the prevailing Nd-Hf isotopic decoupling of the Silurian–Devonian granitoids in the Chinese Altai. | Yanqiong Huang Yingd Jiang Yang Yu Stephen Collett Sheng Wang Tan Shu Kang Xu | 2020 | Journal of Earth Science2020，31，1： | 1 |
| 4 | Robust,fire-resistant,and thermal-stable SiZrNOC nanofiber membranes with amorphous microstructure for high-temperature thermal superinsulation显示文摘Ceramic nanofibers with robust mechanical properties,high-temperature resistance,and superior thermal insulation performance are promising thermal insulators used under extreme conditions.However,developing of ceramic fibers with both low solid thermal conductivity(λs)and low infrared radiation thermal conductivity(λr)is still a great challenge.Herein,according to the Ioffe-Regel limit theory,we report a novel SiZrNOC nanofiber membrane(NFM)with a typically amorphous structure by combining the electrospinning method and high-temperature pyrolysis technique in a NH3 atmosphere.The prepared SiZrNOC NFM has a high tensile strength(1.98±0.09 MPa),excellent thermal stability(1100℃in air),and superior thermal insulation performance.The thermal conductivity of SiZrNOC NFM was 0.112 W·m^(−1)·K^(−1) at 1000℃,which is obviously lower than that of the traditional ceramic fiber membranes(>0.2 W·m^(−1)·K^(−1) at 1000℃).In addition,the prepared SiZrNOC NFM-reinforced SiO2 aerogel composites(SiZrNOCf/SiO2 ACs)exhibited ultralow thermal conductivity of 0.044 W·m^(−1)·K^(−1) at 1000℃,which was the lowest value for SiO2-based aerogel composites ever reported.Such superior thermal insulation performance of SiZrNOC NFMs was mainly due to significant decreasing of solid heat conduction and thermal radiation by the fancy amorphous microstructure and high infrared shielding compositions.This work not only provides a promising high-temperature thermal insulator,but also offers a novel route to develop other high-performance thermal insulating materials. | Xiaoshan ZHANG Nana XU Yonggang JIANG Haiyan LIU Hui XU Cheng HAN Bing WANG Yingde WANG | 2023 | Journal of Advanced Ceramics2023，12，1： | 0 |
