3The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
4Typical atmospheric haze during crop harvest season in northeastern China:A case in the Changchun region显示文摘This study presents the mass concentrations of PM_(2.5),O_3,SO_2 and NOxat one urban,one suburban and two rural locations in the Changchun region from September 25 to October 272013. Major chemical components of PM_(2.5)at the four sites were daily sampled and analyzed. Most of daily concentrations of SO_2(7–82 μg/m^3),O_3(27–171 μg/m^3) and NOx(14–213 μg/m^3) were below the limits of the National Ambient Air Quality Standard(NAAQS)in China. However,PM_(2.5)concentrations(143–168 μg/m^3) were 2-fold higher than NAAQS.Higher PM_(2.5)concentrations(~ 150 μg/m^3) were measured during the pre-harvest and harvest at the urban site,while PM_(2.5)concentrations significantly increased from 250 to400 μg m^(-3) at suburban and rural sites with widespread biomass burning. At all sites,PM_(2.5)components were dominated by organic carbon(OC) and followed by soluble component sulfate(SO_4^(2-)),ammonium(NH_4^+) and nitrate(NO_3^-). Compared with rural sites,urban site had a higher mineral contribution and lower potassium(K^+and K) contribution to PM_(2.5).Severe atmospheric haze events that occurred from October 21 to 23 were attributed to strong source emissions(e.g.,biomass burning) and unfavorable air diffusion conditions.Furthermore,coal burning originating from winter heating supply beginning on October 18 increased the atmospheric pollutant emissions. For entire crop harvest period,the Positive Matrix Factorization(PMF) analysis indicated five important emission contributors in the Changchun region,as follows: secondary aerosol(39%),biomass burning(20%),supply heating(18%),soil/road dust(14%) and traffic(9%).Wei Wei Chen Daniel Q.Tong Mo Dan Shi Chun Zhang Xue Lei Zhang Yue Peng Pan 2017Journal of Environmental Sciences2017,29,4:10
5Effects of rare earth modifying inclusions on the pitting corrosion of 13Cr4Ni martensitic stainless steel显示文摘In this study,the pitting corrosion behavior of 13Cr4Ni martensitic stainless steel(BASE)and that modified with rare earth(REM)in 0.1 mol/L Na Cl solution were characterized.Techniques such as automatic secondary electron microscope(ASPEX PSEM detector),scanning electron microscope(SEM),transmission electron microscope(TEM),scanning Kelvin probe force microscope(SKP),potentiodynamic and potentiostatic polarizations were employed.The results obtained indicate that BASE steel contains Al_(2)O_(3)/Mn S,Al_(2)O_(3) and Mn S inclusions,while REM steels contain(La,Ce,Cr,Fe)-O and(La,Ce,Cr,Fe)-O-S inclusions.Compared with BASE steel,REM steel is more susceptible to induce the metastable pitting nucleation and repassivation,whereas it restrains the transition from metastable pitting to stable pitting.Adding 0.021%rare earth element to BASE steel can reduce the number and area of inclusions,while that of 0.058%can increase the number and enlarged the size of inclusions,which is also the reason that pitting corrosion resistance of 58 REM steel is slightly lower than that of 21 REM steel.In the process of pitting corrosion induced by Al_(2)O_(3)/Mn S inclusions,Mn S is preferentially anodic dissolved,and also the matrix contacted with Al_(2)O_(3) is subsequently anodic dissolved.For REM steels,anodic dissolution preferentially occurs at the boundary between inclusions and matrix,while(La,Ce,Cr,Fe)-O inclusions chemically dissolve in local acidic environment or are separated from steel matrix.The chemically dissolved substance(La^(3+) and Ce^(3+))of(La,Ce,Cr,Fe)-O inclusions are concentrated in pitting pits,which inhibits its continuous growth.Changgang Wang Rongyao Ma Yangtao Zhou Yang Liu Enobong Felix Daniel Xiaofang Li Pei Wang Junhua Dong Wei Ke 2021Journal of Materials Science & Technology2021,,34:8
6Ge-on-Si modulators operating at mid-infrared wavelengths up to 8 μm显示文摘We report mid-infrared Ge-on-Si waveguide-based PIN diode modulators operating at wavelengths of 3.8 and8 μm. Fabricated 1-mm-long electro-absorption devices exhibit a modulation depth of >35 dB with a 7 V forward bias at 3.8 μm, and a similar 1-mm-long Mach–Zehnder modulator has a Vπ· L of 0.47 V · cm. Driven by a 2.5 Vpp RF signal, 60 MHz on-off keying modulation was demonstrated. Electro-absorption modulation at 8 μm was demonstrated preliminarily, with the device performance limited by large contact separation and high contact resistance.TIANTIAN LI MILOS NEDELJKOVIC NANNICHA HATTASAN WEI CAO ZHIBO QU CALLUM GLITTLEJOHNS JORDI SOLER PENADES LORENZO MASTRONARDI VINITA MITTAL DANIEL BENEDIKOVIC DAVID JTHOMSON FREDERIC YGARDES HEQUAN WU ZHIPING ZHOU GORAN ZMASHANOVICH 2019Photonics Research2019,7,8:5
7BLOC-2 subunit HPS6 deficiency affects the tubulation and secretion of von Willebrand factor from mouse endothelial cells显示文摘Hermansky-Pudlak syndrome(HPS) is a recessive disorder with bleeding diathesis, which has been linked to platelet granule defects. Both platelet granules and endothelial Weibel-Palade bodies(WPBs)are members of lysosome-related organelles(LROs) whose formation is regulated by HPS protein associated complexes such as BLOC(biogenesis of lysosome-related organelles complex)-1,-2,-3, AP-3(adaptor protein complex-3) and HOPS(homotypic fusion and protein sorting complex). Von Willebrand factor(VWF) is critical to hemostasis, which is stored in a highly-multimerized form as tubules in the WPBs. In this study, we found the defective, but varying, release of VWF into plasma after desmopressin(DDAVP) stimulation in HPS1(BLOC-3 subunit), HPS6(BLOC-2 subunit), and HPS9(BLOC-1 subunit)deficient mice. In particular, VWF tubulation, a critical step in VWF maturation, was impaired in HPS6 deficient WPBs. This likely reflects a defective endothelium, contributing to the bleeding tendency in HPS mice or patients. The differentially defective regulated release of VWF in these HPS mouse models suggests the need for precise HPS genotyping before DDAVP administration to HPS patients.Jing Ma Zhe Zhang Lin Yang Janos Kriston-Vizi Daniel F.Cutler Wei Lia 2016Journal of Genetics and Genomics2016,43,12:4

9Transformation of erythromycin during secondary effluent soil aquifer recharging:Removal contribution and degradation path显示文摘Erythromycin(ERY),a widely used antibiotic,has recently been detected in municipal secondary effluents and poses serious threats to human health during wastewater reusing.In this study,the removal,fate,and degradation pathway of ERY in secondary effluent during soil aquifer treatment was evaluated via laboratory-scale SAT tests.Up to a 92.9%reduction of ERY in synthetic secondary effluent was observed in 1.0 m depth column system,which decreased to 64.7%when recharged with wastewater treatment plant secondary effluent.XRD-fractionation results demonstrated that the transphilic acid and hydrophobic acid fractions in secondary effluent compete for the adsorption sites of the packed soil and lead to a declined ERY removal.Moreover,aerobic biodegradation was the predominant role for ERY removal,contributing more than 60%reduction of ERY when recharged with synthetic secondary effluent.Destruction of 14-member macrocyclic lactone ring and breakdown of two cyclic sugars(L-cladinose and D-desosamine) were main removal pathways for ERY degradation,and produced six new intermediates.Liangliang Wei Kena Qin Ningbo Zhao Daniel R.Noguera Wei Qiu Qingliang Zhao Xiangjuan Kong Weixian Zhang Felix Tetteh Kabutey 2017Journal of Environmental Sciences2017,29,1:4
10Ophthalmology simulation for undergraduate and postgraduate clinical education显示文摘This is a review education paper on the current ophthalmology simulators utilized worldwide for undergraduate and postgraduate training. At present,various simulators such as the EYE Exam Simulator(Kyoto Kagaku Co. Ltd., Kyoto, Japan), Eyesi direct ophthalmoscope simulator(VRmagic, Gmb H, Mannheim,Germany), Eyesi indirect ophthalmoscope simulator(VRmagic, Gmb H, Mannheim, Germany) and Eyesi cataract simulators(VRmagic, Gmb H, Mannheim,Germany). These simulators are thought to be able to reduce the initial learning curve for the ophthalmology training but further research will need to be conducted to assess the effectiveness of the simulation-assisted ophthalmology training. Future research will be of great value to assess the medical students and residents' responses and performance regarding the usefulness of the individual eye simulator.Daniel Shu Wei Ting Shaun Sebastian Khung Peng Sim Christine Wen Leng Yau Mohamad Rosman Ai Tee Aw Ian Yew San Yeo 2016International Journal of Ophthalmology(English edition)2016,9,6:3
11Empirical estimates of regional carbon budgets imply reduced global soil heterotrophic respiration显示文摘Resolving regional carbon budgets is critical for informing land-based mitigation policy.For nine regions covering nearly the whole globe,we collected inventory estimates of carbon-stock changes complemented by satellite estimates of biomass changes where inventory data are missing.The net land–atmospheric carbon exchange(NEE)was calculated by taking the sum of the carbon-stock change and lateral carbon fluxes from crop and wood trade,and riverine-carbon export to the ocean.Summing up NEE from all regions,we obtained a global‘bottom-up'NEE for net land anthropogenic CO_(2)uptake of–2.2±0.6 Pg C yr^(-1)consistent with the independent top-down NEE from the global atmospheric carbon budget during 2000–2009.This estimate is so far the most comprehensive global bottom-up carbon budget accounting,which set up an important milestone for global carbon-cycle studies.By decomposing NEE into component fluxes,we found that global soil heterotrophic respiration amounts to a source of CO_(2)of 39 Pg C yr^(-1)with an interquartile of 33–46 Pg C yr^(-1)—a much smaller portion of net primary productivity than previously reported.Philippe Ciais Yitong Yao Thomas Gasser Alessandro Baccini Yilong Wang Ronny Lauerwald Shushi Peng Ana Bastos Wei Li Peter A.Raymond Josep G.Canadell Glen P.Peters Rob J.Andres Jinfeng Chang Chao Yue A.Johannes Dolman Vanessa Haverd Jens Hartmann Goulven Laruelle Alexandra G.Konings Anthony W.King Yi Liu Sebastiaan Luyssaert Fabienne Maignan Prabir K.Patra Anna Peregon Pierre Regnier Julia Pongratz Benjamin Poulter Anatoly Shvidenko Riccardo Valentini Rong Wang Grégoire Broquet Yi Yin Jakob Zscheischler Bertrand Guenet Daniel SGoll Ashley-P.Ballantyne Hui Yang Chunjing Qiu Dan Zhu 2021National Science Review2021,8,2:3

13重塑能源-中国:能效在中国面向2050年路线图中的作用显示文摘作为《巴黎协定》承诺的一部分,中国计划在2030年左右达到二氧化碳(CO_2)排放峰值并争取尽早达峰。在研究如何实现上述减排承诺的前提下,中美研究人员组成的团队构建了一个自下而上的中国能源供需综合模型。基于该模型对比分析了两种情景的差异,即沿着当前趋势发展的参考路径情景以及'重塑能源'替代路径情景。'重塑能源'替代路径是指为满足国家需求,在2050年前最大程度地应用当前成本有效的能源效率策略和可再生能源。结果表明,如果中国走更积极的重塑能源路径,那么其二氧化碳排放量可比参考路径提前11年达峰。本文重点分析了在更积极的路径下能源效率策略对于二氧化碳减排的作用。除能源效率外,本研究还分析了燃料替换(从碳密集型燃料转向其他燃料)的减排作用。结果表明,对于重塑能源情景,能源效率提高及相关策略贡献了中国2050年二氧化碳总减排潜力的75%,而燃料替换仅占25%。为在中国实现上述具有显著成本效益的能效潜力。Lynn Price Nina Khanna Nan Zhou David Fridley Ali Hasanbeigi Hongyou Lu Feng Wei 戴彦德 田智宇 杨宏伟 白泉 朱跃中 熊华文 张建国 Jon Creyts Kate Chrisman Ellen Franconi Josh Agenbroad Michael Bendewald Yi Ke Robert McIntosh David Mullaney Clay Stranger Daniel Wetzel Cvrd Yee 2018科学与管理2018,38,3:3
14Comprehensive and high-resolution emission inventory of atmospheric pollutants for the northernmost cities agglomeration of Harbin-Changchun,China:Implications for local atmospheric environment management显示文摘Using a bottom-up estimation method,a comprehensive,high-resolution emission inventory of gaseous and particulate atmospheric pollutants for multiple anthropogenic sectors with typical local sources has been developed for the Harbin-Changchun city agglomeration(HCA).The annual emissions for CO,NO_(x),SO_(2),NH_(3),VOC S,PM_(2.5),PM 10,BC and OC during 2017 in the HCA were estimated to be 5.82 Tg,0.70 Tg,0.34 Tg,0.75 Tg,0.81 Tg,0.67 Tg,1.59 Tg,0.12 Tg and 0.26 Tg,respectively.For PM 10 and SO_(2),the emissions from industry processes were the dominant contributors representing 54.7%and 49.5%,respectively,of the total emissions,while 95.3%and 44.5%of the total NH_(3)and NO x emissions,respectively,were from or associated with agricultural activities and transportation.Spatiotemporal distributions showed that most emissions(except NH_(3))occurred in November to March and were concentrated in the central cities of Changchun and Harbin and the surrounding cities.Open burning of straw made an important contribution to PM_(2.5)in the central regions of the northeastern plain during autumn and spring,while domestic coal combustion for heating purposes was significant with respect to SO_(2)and PM_(2.5)emissions during autumn and winter.Furthermore,based on Principal Component Analysis and Multivariable Linear Regression model,air temperature,relative humidity,electricity and energy consumption,and the urban and rural population were optimized to be representative indicators for rapidly assessing the magnitude of regional atmospheric pollutants in the HCA.Such indicators and equations were demonstrated to be useful for local atmospheric environment management.Mengduo Zhang Weiwei Chen Xiangjin Shen Hongmei Zhao Chengkang Gao Xuelei Zhang Wei Liu Chengjiang Yang Yang Qin Shichun Zhang Jing Fu Daniel Tong Aijun Xiu 2021Journal of Environmental Sciences2021,33,6:3
15Experimental observation of coherent interaction between laser and erbium ions ensemble doped in fiber at sub 10 mK显示文摘Rare-earth ions doped in solid-state materials are considered promising candidates for quantum information applications,especially for photonic quantum memory.Among them,erbium ions doped in an optical fiber have attracted a lot of attentions due to their ability to provide efficient photon-atom interaction on a telecom-C band compatible transition.The coherent photon-atom interaction,which is crucial for quantum memory,has not yet been investigated for erbium ions doped in fiber at the temperature of sub 10 m K with the magnetic environment.In this paper,we experimentally observe optical nutation,which results from the coherent interaction between laser and erbium ions ensemble,in a piece of 9.5-m-long fiber with the erbium concentration of 200 ppm.We also extract the transition dipole moment from the results of optical nutation and further investigate its dependence on laser wavelength and magnetic field.A transition dipole moment of(3.424±0.019)×10^-32 C·m is obtained at the wavelength of 1537 nm and magnetic field of 0.2 T.Our results could pave the way for realizing solid-state quantum networks at telecom-C band.Qi XI Shihai WEI Chenzhi YUAN Xueying ZHANG You WANG Haizhi SONG Guangwei DENG Bo JING Daniel OBLAK Qiang ZHOU 2020Science China(Information Sciences)2020,63,8:3
16Global Wheat Head Detection 2021:An Improved Dataset for Benchmarking Wheat Head Detection Methods显示文摘The Global Wheat Head Detection(GWHD)dataset was created in 2020 and has assembled 193,634 labelled wheat heads from 4700 RGB images acquired from various acquisition platforms and 7 countries/institutions.With an associated competition hosted in Kaggle,GWHD_2020 has successfully attracted attention from both the computer vision and agricultural science communities.From this first experience,a few avenues for improvements have been identified regarding data size,head diversity,and label reliability.To address these issues,the 2020 dataset has been reexamined,relabeled,and complemented by adding 1722 images from 5 additional countries,allowing for 81,553 additional wheat heads.We now release in 2021 a new version of the Global Wheat Head Detection dataset,which is bigger,more diverse,and less noisy than the GWHD_2020 version.Etienne David Mario Serouart Daniel Smith Simon Madec Kaaviya Velumani Shouyang Liu Xu Wang Francisco Pinto Shahameh Shafiee Izzat SATahir Hisashi Tsujimoto Shuhei Nasuda Bangyou Zheng Norbert Kirchgessner Helge Aasen Andreas Hund Pouria Sadhegi-Tehran Koichi Nagasawa Goro Ishikawa Sébastien Dandrifosse Alexis Carlier Benjamin Dumont Benoit Mercatoris Byron Evers Ken Kuroki Haozhou Wang Masanori Ishii Minhajul ABadhon Curtis Pozniak David Shaner LeBauer Morten Lillemo Jesse Poland Scott Chapman Benoit de Solan Frédéric Baret Ian Stavness Wei Guo 2021Plant Phenomics2021,3,1:2
17Impact of postoperative intravenous fluid administration on complications following elective hepato-pancreato-biliary surgery显示文摘Background: The impact of perioperative intravenous fluid administration on surgical outcomes has been documented in literature, but not specifically studied in the context of hepato-pancreato-biliary(HPB) surgery. This study aimed to investigate the impact of postoperative intravenous fluid administration on intensive care unit(ICU), in this subgroup of patients. Methods: A single-center retrospective cohort of 241 HPB patients was assessed, focusing on intravenous fluid administration in ICU, during the first 24 h. Intravenous fluid variables were compared to hospital stay and postoperative complications. Data were assessed using Spearman's correlation test for bivariate correlations and logistic regression for multivariate analysis. Results: The median volume of intravenous fluid administered in the first 24 h postoperatively was 4380 mL, of which 2200 mL was crystalloid, 1500 mL colloid and 680 mL 'other' fluid. Patients with one or more complications had a higher median total intravenous fluid input(4790 vs. 4300 mL), higher colloid volume(20 0 0 vs. 150 0 mL), lower urine output(1595 vs. 1900 mL) and greater overall fluid balance( + 3040 vs. + 2553 mL) than those without complications. There were correlations between total intravenous fluid volume administered( r = 0.278, P < 0.001), intravenous colloid input( r = 0.278, P < 0.001), urine output( r =-0.295, P < 0.001), positive fluid balance( r = 0.344, P < 0.001) and length of hospital stay. Logistic regression model was constructed to predict the occurrence of one or more complications; total intravenous fluid volume and overall fluid balance were both independent significant predictors(OR = 2.463, P = 0.007; OR = 1.001, P = 0.011; respectively). Conclusions: Administration of high volumes of intravenous fluids in the first 24 hours post-HPB surgery, along with higher positive fluid balance is associated with a higher rate of complications and longer hospital stay. Moreover, lower urine output is associated with longer hospital stay. Whether these are the cause of complications or the result of them remains unclear.Daniel Martin Panagis M.Lykoudis Gabriel Jones David Highton Alan Shaw Sarah James Qiang Wei Giuseppe Fusai 2018Hepatobiliary & Pancreatic Diseases International2018,17,5:2

19Eddies in the Northwest Subtropical Pacific and Their Possible Effects on the South China Sea显示文摘Based on an analysis of drifter data from the World Ocean Circulation Experiment during 1979-1998, the sizes of the eddies in the North subtropical Pacific are determined from the radii of curvature of the drifter paths calculated by using a non-linear curve fitting method. To support the drifter data results, Sea Surface Height from the TOPEX/POSEIDON and ERS2 satellite data are analyzed in connection with the drifter paths. It is found that the eddies in the North Pacific (18°-23°N and 125°-150°E) move westward at an average speed of approximately 0.098 ms-1 and their average radius is 176 km,with radii ranging from 98 km to 298 km. During the nineteen-year period, only 4 out of approximately 200 drifters (2%)actually entered the South China Sea from the area adjacent to the Luzon Strait (18°-22°N and 121°-125°E) in the winter. It is also found that eddies from the interior of the North Pacific are unlikely to enter the South China Sea through the Luzon Strait.LIU Qinyu Daniel Souza JIA Yinglai LIU Wei 2005Journal of Ocean University of China2005,4,4:2
20Silica-coating-assisted nitridation of TiO_(2) nanoparticles and their photothermal property显示文摘Nanoparticles of refractory compounds represent a class of stable materials showing a great promise to support localized surface plasmon resonances(LSPRs)in both visible and near infrared(NIR)spectral regions.It is still challenging to rationally tune the LSPR band because of the difficulty to control the density of charge carriers in individual refractory nanoparticles and maintain the dispersity of nanoparticles in the processes of synthesis and applications.In this work,controlled chemical transformation of titanium dioxide(TiO_(2))nanoparticles encapsulated with mesoporous silica(SiO_(2))shells to titanium nitride(TiN)via nitridation reaction at elevated temperatures is developed to tune the density of free electrons in the resulting titanium-oxide-nitride(TiO_(x)N_(y))nanoparticles.Such tunability enables a flexibility to support LSPR-based optical absorption in the synthesized TiO_(x)N_(y)@SiO_(2) core-shell nanoparticles across both the visible and NIR regions.The silica shells play a crucial role in preventing the sintering of TiO_(x)N_(y) nanoparticles in the nitridation reaction and maintaining the stability of TiOxNy nanoparticles in applications.The LSPR-based broadband absorption of light in the TiO_(x)N_(y)@SiO_(2) nanoparticles exhibits strong photothermal effect with photo-to-thermal conversion efficiency as high as〜76%.Qilin Wei Danielle L.Kuhn Zachary Zander Brendan G.DeLacy Hai-Lung Dai Yugang Sun 2021Nano Research2021,14,9:2
