| 1 | Large-area straight,regular periodic surface structures produced on fused silica by the interference of two femtosecond laser beams through cylindrical lens显示文摘Inhomogeneity and low efficiency are two important factors that limit the application of laser-induced periodic surface structures(LIPSSs),especially on glass surfaces.In this study,two-beam interference(TBI)of femtosecond lasers was used to produce large-area straight LIPSSs on fused silica using cylindrical lenses.Compared with those produced us-ing a single circular or cylindrical lens,the LIPSSs produced by TBI are much straighter and more regular.Depending on the laser fluence and scanning velocity,LIPSSs with grating-like or spaced LIPSSs are produced on the fused silica sur-face.Their structural colors are blue,green,and red,and only green and red,respectively.Grating-like LIPSS patterns oriented in different directions are obtained and exhibit bright and vivid colors,indicating potential applications in surface coloring and anti-counterfeiting logos. | Long Chen Kaiqiang Cao Yanli Li Jukun Liu Shian Zhang Donghai Feng Zhenrong Sun Tianqing Jia | 2021 | Opto-Electronic Advances2021，4，12： | 7 |

| 4 | A biomimetic bi-layered tissue engineering scaffolds for osteochondral defects repair显示文摘Osteochondral defects are most commonly characterized by damages to both cartilage and underlying subchondral bone tissues,thus developing bi-layered scaffold that can concurrently regenerate these two specific lineages becomes challenge.In this study,the highly biomimetic bi-layered scaffolds were successfully prepared using human-like-collagen(HLC),hyaluronan(HA)and nano hydroxyapatite(HAP)particles,combined with'liquid phase synthesis'technology,freeze-drying and chemical crosslinking techniques,which was simulated the composition of natural extracellular matrix to repair osteochondral defects.This novel bilayer osteochondral graft had a seamlessly integrated layer structure,suitable pore size,high levels of porosity,and excellent mechanical properties.In vitro cell experiments of the bilayer scaffold indicated that the scaffold could promote the proliferation and adhesion of human bone marrow mesenchymal stem cells.In vivo osteochondral defects and micro-CT experiment revealed that bilayer scaffolds showed complete closure of the defect.Histology confirmed collagen and glycosaminoglycans were deposited in the new matrix of hyaline cartilage and bone in the bilayer scaffold group.Therefore,the developed bionic bilayer scaffold enhanced the regeneration of hyaline cartilage through subchondral bone formation and lateral host-tissue integration.In conclusion,this bilayer scaffold based on HLC could be used as the desired strategy for osteochondral defects regeneration. | LIU KaiQiang LIU YanNan DUAN ZhiGuang MA XiaoXuan FAN DaiDi | 2021 | Science China(Technological Sciences)2021，64，4： | 4 |
| 5 | In-situ transient photovoltage study on interface electron transfer regulation of carbon dots/NiCo_(2)O_(4) photocatalyst for the enhanced overall water splitting activity显示文摘Photocatalytic hydrogen production by overall water solar-splitting is a prospective strategy to solve energy crisis.However,the rapid recombination of photogenerated electron–hole pairs deeply restricts photocatalytic activity of catalysts.Here,the in-situ transient photovoltage(TPV)technique was developed to investigate the interfacial photogenerated carrier extraction,photogenerated carrier recombination and the interfacial electron delivery kinetics of the photocatalyst.The carbon dots/NiCo_(2)O_(4)(CDs/NiCo_(2)O_(4))composite shows weakened recombination rate of photogenerated carriers due to charge storage of CDs,which enhances the photocatalytic water decomposition activity without any scavenger.CDs can accelerate the interface electron extraction about 0.09 ms,while the maximum electron storage time by CDs is up to 0.7 ms.The optimal CDs/NiCo_(2)O_(4)composite(5 wt.%CDs)displays the hydrogen production of 62µmol·h^(−1)·g^(−1) and oxygen production of 29µmol·h^(−1)·g^(−1) at normal atmosphere,which is about 4 times greater than that of pristine NiCo_(2)O_(4).This work provides sufficient evidence on the charge storage of CDs and the interfacial charge kinetics of photocatalysts on the basis of in-situ TPV tests. | Haodong Nie Yan Liu Yi Li Kaiqiang Wei Zhenyu Wu Hong Shi Hui Huang Yang Liu Mingwang Shao Zhenhui Kang | 2022 | Nano Research2022，15，3： | 2 |
| 6 | Synthesis and gelation behaviors of five new dimeric cholesteryl derivatives显示文摘Five new diacid amides of di-cholesteryl L-glycinates were designed and prepared.The compounds with linkers containing 0,1, 2,3,or 4 methylene units are denoted as 1,2,3,4,and 5,respectively.Their gelation behaviors in 25 solvents were tested as novel low-molecular-mass organic gelators(LMOGs).It was shown that the length of the linker connecting the two-cholesteryl residues in a gelator plays a crucial role in the gelation behavior of the compound.1 gels 11 of the 25 solvents tested at a concentration lower than 1.0%,while 2 gels 17 of the solvents tested.4 and 5,however,gel only 2 and 4 of them,respectively. SEM observation reveals that the lengths of the linkers and the identity of the solvents are the main factors affecting the structures of the aggregates in the gels.Experimentally,a clear linker effect on the microstructures of the gels was observed.As example,the aggregates of 1,2 and 3 in benzene or 1-heptanol adopt structures of thin fibers,rods or lamellas,respectively. Furthermore,it was found that the gelation and aggregation behaviors of 2,3,4,and 5 in DMSO showed an even-odd effect. | LIU KaiQiang PENG JunXia XUE Min YAN Ni LIU Jing FANG Yu | 2011 | Science China Chemistry2011，54，3： | 2 |
| 7 | Spotted Sea Bass(Lateolabrax maculatus) cftr, nkcc1a, nkcc1b and nkcc2: Genome-Wide Identification, Characterization and Expression Analysis Under Salinity Stress显示文摘The Na^+/K^+/2Cl^-cotransporter(NKCC)and the cystic fibrosis transmembrane conductance regulator(CFTR)proteins play crucial roles in the transportation of Na^+and Cl^-.In this study,we identified cftr,nkcc1 a,nkcc1 b and nkcc2 in spotted sea bass(Lateolabrax maculatus)genomic and transcriptomic databases.We also characterized these genes via phylogenetic and structural analyses.The results showed that both cftr and nkcc were highly conservative in L.maculatus.Quantitative real-time polymerase chain reaction(qRT-PCR)analysis in ten tissues showed that cftr,nkcc1 a and nkcc2 highly express in osmoregulatory organs such as gill,kidney and intestine.Furthermore,the expressions of cftr and nkcc1 a in gill as well as nkcc2 in intestine were up-regulated by high salinity,indicating that these genes function potentially in osmoregulation.Our findings provided the insights into the cftr and nkcc functions in euryhaline teleost. | ZHANG Kaiqiang ZHANG Xiaoyan WEN Haishen QI Xin FAN Hongying TIAN Yuan LIU Yang LI Yun | 2019 | Journal of Ocean University of China2019，18，6： | 2 |

| 9 | Effects of Soil Testing and Formulated Fertilization on Yield and Economic Benefit of Major Crops in Burundi显示文摘[Objectives]The purpose of this study was to provide technical support for high-yield cultivation of major crops in Burundi,thereby increasing local farmers'income and promoting sustainable development of agriculture in Burundi.[Methods]In the IMBO and MOSO test stations of the Burundi Academy of Agricultural Sciences and the Burundi Fruit and Vegetable Extension and Service Center,soil testing and formulated fertilization test and demonstration was carried out in rice,maize and cabbage.The test set up three treatments,soil testing and formulated fertilization(STFF),local routine fertilization(RF)and non-fertilization(CK)to investigate the effects of soil testing and formulated fertilization on the yield and economic benefit of the crops.[Results]In the plot test,the yield and net economic benefit of rice,maize and cabbage were both highest in the STFF treatment.Compared with those in the RF treatment,the yield of rice,maize and cabbage increased by 19.0%,25.7%and 33.0%,respectively,and the net economic benefit increased by 4292,2837 and 8232 yuan/ha,respectively.In the field test,the yield and net economic benefit of rice,maize and cabbage were also both highest in the STFF treatment.The yield increased by 18.1%,24.3%and 25.9%,respectively,and the net economic benefit increased by 4142,2881 and 8665 yuan/ha,respectively compared with those in the RF treatment.[Conclusions]Soil testing and formulated fertilization not only increased rice,maize and cabbage yield per unit area,but also increased farmers'income in Burundi.It is one of the important technical measures to promote the increase of agricultural production and income in Burundi. | Kaiqiang LIU Yuyi HUANG Yanfei HUANG Guifen CHEN Guoqing GAO | 2020 | Asian Agricultural Research2020，12，3： | 1 |
| 10 | Preparation of a scorpion-shaped di-NBD derivative of cholesterol and its thixotropic property显示文摘A scorpion-shaped di-NBD(4-substituted-7-nitrobenzoxadiazole) derivative of cholesterol(Chol-2NBD) was designed and synthesized. The gelation behaviors of the compound in a series of single and mixed liquids were tested. It was shown that the compound is an effective gelator for mixture liquids of THF and benzene at room temperature. Furthermore, FT-IR and temperature-/concentration-dependent 1H NMR spectroscopy studies revealed that hydrogen bonding and π-π stacking among the molecules of Chol-2NBD are two main driving forces for the physical gelation of the mixture liquids. Interestingly, as observed in the gelation test and confirmed by rheological studies, the Chol-2NBD-THF/benzene gel systems, at least the one with 2:8 of the volume ratio of THF to benzene, are mechanically stable, but very sensitive to the stimulus of shear stress, which means that the gel changes into a liquid upon shaking. More interestingly, the liquid returns to gel instantly once the shear stress is removed. This phase transition process could be repeated for many times at room temperature. In addition, primary tests demonstrated that the fluorescence emission of Chol-2NBD is significantly quenched by the presence of water, ammonia water, or ammonia gas, but the emission recovers after evaporation of them. Further detailed investigation is under progress. | HU BaoLong LIU KaiQiang CHEN XiangLi FANG Yu | 2014 | Science China Chemistry2014，57，11： | 1 |

| 12 | Single-cell-resolution transcriptome map revealed novel genes involved in testicular germ cell progression and somatic cells specification in Chinese tongue sole with sex reversal显示文摘Female-to-male sex reversals(pseudomales)are common in lower vertebrates and have been found in natural populations,which is a concern under rapid changes in environmental conditions.Pseudomales can exhibit altered spermatogenesis.However,the regulatory mechanisms underlying pseudomale spermatogenesis remain unclear.Here,we characterized spermatogenesis in Chinese tongue sole(Cynoglossus semilaevis),a species with genetic and environmental sex determination,based on a highresolution single-cell RNA-seq atlas of cells derived from the testes of genotypic males and pseudomales.We identified five germ cell types and six somatic cell types and obtained a single-cell atlas of dynamic changes in gene expression during spermatogenesis in Chinese tongue sole,including alterations in pseudomales.We detected decreased levels of Ca^(2+)signaling pathway-related genes in spermatogonia,insufficient meiotic initiation in spermatocytes,and a malfunction of somatic niche cells in pseudomales.However,a cluster of CaSR genes and MAPK signaling factors were upregulated in undifferentiated spermatogonia of pseudomales.Additionally,we revealed that Z chromosome-specific genes,such as piwil2,dhx37,and ehmt1,were important for spermatogenesis.These results improve our understanding of reproduction after female-to-male sex-reversal and provide new insights into the adaptability of reproductive strategies in lower vertebrates. | Hong-Yan Wang Xiang Liu Jian-Yang Chen Yingyi Huang Yifang Lu Fujian Tan Qun Liu Mingming Yang Shuo Li Xianghui Zhang Yating Qin Wenxiu Ma Yingming Yang Liang Meng Kaiqiang Liu Qian Wang Guangyi Fan Rafael H.Nóbrega Shanshan Liu Francesc Piferrer Changwei Shao | 2023 | Science China(Life Sciences)2023，66，5： | 1 |
| 13 | Ample dietary fat reduced the risk of primary vesical calculi by inducing macrophages to engulf budding crystals in mice显示文摘Although primary vesical calculi is an ancient disease,the mechanism of calculi formation remains unclear.In this study,we established a novel primary vesical calculi model with D,L-choline tartrate in mice.Compared with commonly used melamine and ethylene glycol models,our model was the only approach that induced vesical calculi without causing kidney injury.Previous studies suggest that proteins in the daily diet are the main contributors to the prevention of vesical calculi,yet the effect of fat is overlooked.To assay the relationship of dietary fat with the formation of primary vesical calculi,D,L-choline tartrate-treated mice were fed a high-fat,low-fat,or normal-fat diet.Genetic changes in the mouse bladder were detected with transcriptome analysis.A high-fat diet remarkably reduced the morbidity of primary vesical calculi.Higher fatty acid levels in serum and urine were observed in the high-fat diet group,and more intact epithelia in bladder were observed in the same group compared with the normal-and low-fat diet groups,suggesting the protective effect of fatty acids on bladder epithelia to maintain its normal histological structure.Transcriptome analysis revealed that the macrophage differentiation-related gene C-X-C motif chemokine ligand 14(Cxcl14)was upregulated in the bladders of high-fat diet-fed mice compared with those of normal-or low-fat diet-fed mice,which was consistent with histological observations.The expression of CXCL14 significantly increased in the bladder in the high-fat diet group.CXCL14 enhanced the recruitment of macrophages to the crystal nucleus and induced the transformation of M2 macrophages,which led to phagocytosis of budding crystals and prevented accumulation of calculi.In human bladder epithelia(HCV-29)cells,high fatty acid supplementation significantly increased the expression of CXCL14.Dietary fat is essential for the maintenance of physiological functions of the bladder and for the prevention of primary vesical calculi,which provides new ideas for the reduction of morbidity of primary vesical calculi. | Huiling Chen Kaiqiang Hu Yaru Liang Yuqi Gao Chenye Zeng Kang Xu Xiaojin Shi Liyuan Li Yuemiao Yin Yi Qiao Ying Qiu Qingfei Liu Zhao Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 1 |
| 14 | 2D layered black arsenic-phosphorus materials:Synthesis,properties,and device applications显示文摘Phosphorene,especially black phosphorus(BP),has attracted considerable attention due to the unique characteristics,such as tunable direct bandgap,high carrier mobility,and strong in-plane anisotropy.Recently,a new modification strategy for black phosphorus has been developed by alloying black phosphorus with the congener element arsenic.The elemental composition tuning of black phosphorus with arsenic can not only maintain its special crystal structure and high anisotropy but also modify its electrical and optical properties for the further applications of multifunctional devices.The achieved two-dimensional(2D)black arsenic-phosphorus materials exhibit outstanding optical,electrical,and photoelectric properties,such as very narrow band gap,anisotropic infrared absorption,and bipolar transfer characteristics,presenting great potential in infrared photodetectors and highperformance field effect transistors(FETs).In this review,we introduce the recent progress made in the synthesis and applications of black arsenic-phosphorus,and provide an outlook and perspectives on the current challenges and future opportunities in this field.We hope that this review can bring new insights and inspirations on the further development of 2D black arsenic-phosphorus based materials and devices. | Junchuan Liang Yi Hu Kaiqiang Zhang Yaoda Wang Xinmei Song Anyang Tao Yuzhu Liu Zhong Jin | 2022 | Nano Research2022，15，4： | 1 |

| 17 | Carbon dots regulate the interface electron transfer and catalytic kinetics of Pt-based alloys catalyst for highly efficient hydrogen oxidation显示文摘The regulation of interface electron-transfer and catalytic kinetics is very important to design the efficient electrocatalyst for alkaline hydrogen oxidation reaction(HOR).Here,we show the Pt-Ni alloy nanoparticles(PtNi_(2))have an enhanced HOR activity compared with single component Pt catalyst.While,the interface electron-transfer kinetics of PtNi_(2)catalyst exhibits a very wide electron-transfer speed distribution.When combined with carbon dots(CDs),the interface charge transfer of PtNi_(2)-CDs composite is optimized,and then the PtNi_(2)-5 mg CDs exhibits about 2.67 times and 4.04 times higher mass and specific activity in 0.1 M KOH than that of 20%commercial Pt/C.In this system,CDs also contribute to trapping H^(+)and H_(2)O generated during HOR,tuning hydrogen binding energy(HBE),and regulating interface electron transfer.This work provides a deep understanding of the interface catalytic kinetics of Pt-based alloys towards highly efficient HOR catalysts design. | Jie Wu Yunjie Zhou Haodong Nie Kaiqiang Wei Hui Huang Fan Liao Yang Liu Mingwang Shao Zhenhui Kang | 2022 | Journal of Energy Chemistry2022，31，3： | 1 |
