| 3 | Rare earth oxides and their supported noble metals in application of environmental catalysis显示文摘Volatile organic compounds(VOCs),methane,carbon monoxide,soot,automotive exhaust,and nitrogen oxides are harmful to the atmosphere and human health.It is urgent to strictly control their emissions.Heterogeneous catalysis is an effective pathway for the removal of these pollutants,and the critical issue is the development of novel and high-performance catalysts.In this review,we briefly summarize the preparation methods,physicochemical properties,catalytic activities,and related reaction mechanisms for the above pollutants removal of the rare earth oxides,mixed rare earth oxide,rare earth oxidesupported noble metal,and mixed rare earth oxide-supported noble metal catalysts that have been investigated by our group and other researchers.It was found that catalytic performance was associated with the factors,such as specific surface area,pore structure,particle size and dispersion,adsorbed oxygen species concentration,reducibility,reactant activation ability or interaction between metal nanoparticles and support.Furthermore,we also envision the development trend of such a topic in future work. | Zhiquan Hou Wenbo Pei Xing Zhang Kunfeng Zhang Yuxi Liu Jiguang Deng Lin Jing Hongxing Dai | 2020 | Journal of Rare Earths2020，38，8： | 10 |
| 4 | Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases. | Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao | 2020 | Bone Research2020，8，1： | 8 |
| 5 | PdAg bimetallic electrocatalyst for highly selective reduction of CO2 with low COOH^* formation energy and facile CO desorption显示文摘For electrocatalytic reduction of CO2 to CO,the stabilization of intermediate COOH^* and the desorption of CO^* are two key steps.Pd can easily stabilize COOH^*,whereas the strong CO^* binding to Pd surface results in severe poisoning,thus lowering catalytic activity and stability for CO2 reduction.On Ag surface,CO^* desorbs readily,while COOH^* requires a relatively high formation energy,leading to a high overpotential.In light of the above issues,we successfully designed the PdAg bimetallic catalyst to circumvent the drawbacks of sole Pd and Ag.The PdAg catalyst with Ag-terminated surface not only shows a much lower overpotential(-0.55 V with CO current density of 1 mA/cm^2)than Ag(−0.76 V),but also delivers a CO/H2 ratio 18 times as high as that for Pd at the potential of-0.75 V vs.RHE.The issue of CO poisoning is significantly alleviated on Ag-terminated PdAg surface,with the stability well retained after 4h electrolysis at-0.75 V vs.RHE.Density functional theory(DFT)calculations reveal that the Ag-terminated PdAg surface features a lowered formation energy for COOH^* and weakened adsorption for CO^*,which both contribute to the enhanced performance for CO2 reduction. | Rui Lin Xuelu Ma Weng-Chon Cheong Chao Zhang Wei Zhu Jiajing Pei Kaiyue Zhang Bin Wang Shiyou Liang Yuxi Liu Zhongbin Zhuang Rong Yu Hai Xiao Jun Li Dingsheng Wang Qing Peng Chen Chen Yadong Li | 2019 | Nano Research2019，12，11： | 7 |
| 6 | Influence of post-heat treatment on the microstructure and mechanical properties of Al-Cu-Mg-Zr alloy manufactured by selective laser melting显示文摘The properties of modified conventional wrought aluminum alloys cannot be significantly enhanced by normal post-heat treatment in that the fine-grained strengthening,arising from high cooling rate in SLM,is underutilized.In this work,compared with the normal T6 heat treatment,a novel simple direct aging regime was proposed to maintain the grain-boundary strengthening and to utilize the precipitation strengthening of secondary AlZr.It was found that a heterogeneous grain structure,which consisted of ultrafine equiaxed(~0.82μm)and columnar(~1.80μm)grains at the bottom and top of molten pool,respectively,was formed in the SLM processed sample.After direct aging(DA),the ultrafine grains were maintained and a mass of spherical coherent L1-AlZr particles with a mean radius of approximately1.15 nm was precipitated.In contrast,after solution treatment and aging(STA),a significant grain coarsening occurred in the equiaxed grain region.Meanwhile,the coarsening L1-AlZr particles,nano-sized S phases and GPB zones were detected in the STA sample.This subsequently induced that the yield strength of the DA sample(~435 MPa)was higher than that of the STA sample(~402 MPa)owing to the grain boundary strengthening and precipitation strengthening.Both the STA and DA samples exhibited a higher strength than that of the other SLMed Al-Cu-Mg series alloys;this was comparable to that of the wrought AA2024-T6 alloy(~393 MPa).Both the STA and DA samples exhibited a higher strength than that of the other SLMed Al-Cu-Mg series alloys;this was comparable to that of the wrought AA2024-T6alloy(~393 MPa). | Yanfang Wang Xin Lin Nan Kang Zihong Wang Yuxi Liu Weidong Huang | 2022 | Journal of Materials Science & Technology2022，，16： | 5 |
| 7 | Atomic force microscopic observation on substructure of pollen exine in Cedrus deodara and Metasequoia glyptostroboides显示文摘The substructure of pollen exine in Cedrus deodara (Roxb.) Loud, and Metasequoia glyptostroboides Hu et Cheng has been examined with an atomic force microscope (AFM). The results indicate that the exine substructure units containing sporopollenin in two species are similar in shape, which are granular, but slightly different in size. In Cedrus the substructure unit of pollen exine appears to be 56-99 nm long and 42-74 nm wide, while in Metasequoia it appears to be 81-118 nm long and 43-98 nm wide. It has been observed that the subunits of pollen exine in Cedrus arranged tightly to form short-rod-like or spheroidal pollen exine units, several or more than ten of which formed an island-like structure. There are various spaces among these island-like structures which are interconnected to occupy the entire pollen exine. In Metasequoia, the subunits of pollen exine also arranged tightly with a distribution tendency of cluster of 3-10, however, no obvious boundary exists among these clusters.

| 10 | Nucleic acids and analogs for bone regeneration显示文摘With the incidence of different bone diseases increasing, effective therapies are needed that coordinate a combination of various technologies and biological materials. Bone tissue engineering has also been considered as a promising strategy to repair various bone defects. Therefore, different biological materials that can promote stem cell proliferation, migration, and osteoblastic differentiation to accelerate bone tissue regeneration and repair have also become the focus of research in multiple fields. Stem cell therapy, biomaterial scaffolds, and biological growth factors have shown potential for bone tissue engineering; however, off-target effects and cytotoxicity have limited their clinical use. The application of nucleic acids(deoxyribonucleic acid or ribonucleic acid)and nucleic acid analogs(peptide nucleic acids or locked nucleic acids), which are designed based on foreign genes or with special structures, can be taken up by target cells to exert different effects such as modulating protein expression, replacing a missing gene, or targeting specific gens or proteins. Due to some drawbacks, nucleic acids and nucleic acid analogs are combined with various delivery systems to exert enhanced effects, but current studies of these molecules have not yet satisfied clinical requirements. In-depth studies of nucleic acid or nucleic acid analog delivery systems have been performed, with a particular focus on bone tissue regeneration and repair. In this review, we mainly introduce delivery systems for nucleic acids and nucleic acid analogs and their applications in bone repair and regeneration. At the same time, the application of conventional scaffold materials for the delivery of nucleic acids and nucleic acid analogs is also discussed. | Yuxin Zhang Wenjuan Ma Yuxi Zhan Chenchen Mao Xiaoru Shao Xueping Xie Xiawei Wei Yunfeng Lin | 2018 | Bone Research2018，6，4： | 3 |
| 11 | Multi?targeted Antisense Oligonucleotide Delivery by a Framework Nucleic Acid for Inhibiting Biofilm Formation and Virulence显示文摘Biofilm formation is responsible for numerous chronic infections and represents a serious health challenge.Bacteria and the extracellular polysaccharides(EPS)cause biofilms to become adherent,toxic,resistant to antibiotics,and ultimately difficult to remove.Inhibition of EPS synthesis can prevent the formation of bacterial biofilms,reduce their robustness,and promote removal.Here,we have developed a framework nucleic acid delivery system with a tetrahedral configuration.It can easily access bacterial cells and functions by delivering antisense oligonucleotides that target specific genes.We designed antisense oligonucleotide sequences with multiple targets based on conserved regions of the VicK protein-binding site.Once delivered to bacterial cells,they significantly decreased EPS synthesis and biofilm thickness.Compared to existing approaches,this system is highly efficacious because it simultaneously reduces the expression of all targeted genes(gtfBCD,gbpB,ftf).We demonstrate a novel nucleic acid-based nanomaterial with multi-targeted inhibition that has great potential for the treatment of chronic infections caused by biofilms. | Yuxin Zhang Xueping Xie Wenjuan Ma Yuxi Zhan Chenchen Mao Xiaoru Shao Yunfeng Lin | 2020 | Nano-Micro Letters2020，12，6： | 3 |
| 12 | Au-Pd/mesoporous Fe_2O_3:Highly active photocatalysts for the visible-light-driven degradation of acetone显示文摘Three-dimensionally ordered mesoporous Fe_2O_3(meso-Fe_2O_3) and its supported Au, Pd,and Au-Pd alloy(xA uP dy/meso-Fe_2O_3; x = 0.08–0.72 wt.%; Pd/Au molar ratio(y) = 1.48–1.85)photocatalysts have been prepared via the KIT-6-templating and polyvinyl alcohol-protected reduction routes, respectively. Physical properties of the samples were characterized, and their photocatalytic activities were evaluated for the photocatalytic oxidation of acetone in the presence of a small amount of H_2O_2 under visible-light illumination. It was found that the meso-Fe_2O_3 was rhombohedral in crystal structure. The as-obtained samples displayed a high surface area of 111.0–140.8 m^2/g and a bandgap energy of 1.98–2.12 eV. The Au, Pd and/or Au–Pd alloy nanoparticles(NPs) with a size of 3–4 nm were uniformly dispersed on the surface of the meso-Fe_2O_3 support. The 0.72 wt.% AuP d1.48/meso-Fe_2O_3 sample performed the best in the presence of 0.06 mol/L H_2O_2 aqueous solution, showing a 100% acetone conversion within4 hr of visible-light illumination. It was concluded that the good performance of 0.72 wt.%AuPd_(1.48)/meso-Fe_2O_3 for photocatalytic acetone oxidation was associated with its ordered mesoporous structure, high adsorbed oxygen species concentration, plasmonic resonance effect between AuPd_(1.48) NPs and meso-Fe_2O_3, and effective separation of the photogenerated charge carriers. In addition, the introduction of H_2O_2 and the involvement of the photo-Fenton process also played important roles in enhancing the photocatalytic activity of 0.72 wt.%AuPd_(1.48)/meso-Fe_2O_3. | Hongxia Lin Yuxi Liu Jiguang Deng Kunfeng Zhang Xing Zhang Shaohua Xie Xingtian Zhao Jun Yang Zhuo Han Hongxing Dai | 2018 | Journal of Environmental Sciences2018，30，8： | 2 |
| 13 | Photocatalytic degradation of mixed pollutants in aqueous wastewater using mesoporous 2D/2D TiO_(2)(B)-BiOBr heterojunction显示文摘There are multiple contaminants in practical wastewater;and the photodegradation of mixed pollutants is a challenge in the field of photocatalysis.Herein,we design a mesoporous 2D/2D TiO_(2)(B)-BiOBr heterojunction photocatalyst for the photodegradation of mixed pollutants.Such a coupling structure results in an enhancement in the disconnection of photoexcited carriers,and the increase of absorption and reaction sites.The 2D/2D TiO_(2)(B)-BiOBr demonstrates outstanding photocatalytic activity for photodegrading rhodamine B(RhB),methyl orange(MO),tetracycline hydrochloride(TCH),and bisphenol A(BPA)simultaneously under visible light,which is 4.7,1.4,23 and 16.4 times as high as that of original BiOBr,respectively.Our work represents a possible solution to devise promising and efficient photocatalysts for the treatment of practical wastewater in the near future. | Liping Han Bo Li Hao Wen Yuxi Guo Zhan Lin | 2021 | Journal of Materials Science & Technology2021，，11： | 2 |
| 14 | The biological applications of DNA nanomaterials:current challenges and future directions显示文摘DNA,a genetic material,has been employed in different scientific directions for various biological applications as driven by DNA nanotechnology in the past decades,including tissue regeneration,disease prevention,inflammation inhibition,bioimaging,biosensing,diagnosis,antitumor drug delivery,and therapeutics.With the rapid progress in DNA nanotechnology,multitudinous DNA nanomaterials have been designed with different shape and size based on the classic Watson–Crick base-pairing for molecular self-assembly.Some DNA materials could functionally change cell biological behaviors,such as cell migration,cell proliferation,cell differentiation,autophagy,and anti-inflammatory effects.Some single-stranded DNAs(ssDNAs)or RNAs with secondary structures via self-pairing,named aptamer,possess the ability of targeting,which are selected by systematic evolution of ligands by exponential enrichment(SELEX)and applied for tumor targeted diagnosis and treatment.Some DNA nanomaterials with three-dimensional(3D)nanostructures and stable structures are investigated as drug carrier systems to delivery multiple antitumor medicine or gene therapeutic agents.While the functional DNA nanostructures have promoted the development of the DNA nanotechnology with innovative designs and preparation strategies,and also proved with great potential in the biological and medical use,there is still a long way to go for the eventual application of DNA materials in real life.Here in this review,we conducted a comprehensive survey of the structural development history of various DNA nanomaterials,introduced the principles of different DNA nanomaterials,summarized their biological applications in different fields,and discussed the current challenges and further directions that could help to achieve their applications in the future. | Wenjuan Ma Yuxi Zhan Yuxin Zhang Chenchen Mao Xueping Xie Yunfeng Lin | 2021 | Signal Transduction and Targeted Therapy2021，6，11： | 2 |

Not only the structures which are visible by the conventional method, but also the three-dimensional structures of pits pair in intertracheids unvisualized by the normal way have been observed. Moreover, it is found that there exist many differences in the angle, trend and occurrence of helical thickenings and distribution of warty layers on the inner walls of tracheids in normal and compression wood. | Jianhua Xu Yuxi Hu Jinxing Lin | 1999 | Chinese Science Bulletin1999，44，15： | 2 |
