2Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration.Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen 2019National Science Review2019,6,4:21

5A new bone repair scaffold combined with chitosan/ hydroxyapatite and sustained releasing icariin显示文摘Icariin, a plant-derived flavonol glycoside, has been proved as an osteoinductive agent for bone tissue engineering. A new bone repair scaffold was generated by thorough mixing of icariin and chitosan/ hydroxyapatite (icariin-CS/HA) using freeze-drying technigue. Characteristics of morphology, mechanical properties, biocompatibility, drug release behavior and bone repair abilities in vivo were evaluated. The results show that drug loading process of icariin did not affect physical structure of CS/HA composite significantly but decreased mechanical properies of CS/HA composite, which happened with a high dosage; icariin-CS/HA had favorable cell compatibility and promoted osteogenic differentiation of hBMSCs; the controlled release of icariin was satisfactory and the release retained after 90 d in vitro. In addition, icariin-CS/HA scaffolds had favorable osteoconduction and osteoinduction in vivo, and could fill bone defect sites and stimulate newborn bone tissues formation at early stage. On the basis of these data, icariin-CS/HA is believed to be an optical bone repair scaffold for tissue engineering.WU Tao NAN KaiHui CHEN JingDi JIN Dan JIANG Shan ZHAO PeiRan XU JunChang DU Hao ZHANG XiaoQiang LI JianWei PEI GuoXian 2009Chinese Science Bulletin2009,54,17:14
6Role of gut microbiota via the gut-liver-brain axis in digestive diseases显示文摘The gut-brain axis is a bidirectional information interaction system between the central nervous system(CNS) and the gastrointestinal tract, in which gut microbiota plays a key role. The gut microbiota forms a complex network with the enteric nervous system, the autonomic nervous system, and the neuroendocrine and neuroimmunity of the CNS, which is called the microbiota-gut-brain axis. Due to the close anatomical and functional interaction of the gut-liver axis, the microbiota-gut-liver-brain axis has attracted increased attention in recent years. The microbiota-gut-liver-brain axis mediates the occurrence and development of many diseases, and it offers a direction for the research of disease treatment. In this review, we mainly discuss the role of the gut microbiota in the irritable bowel syndrome, inflammatory bowel disease, functional dyspepsia, non-alcoholic fatty liver disease, alcoholic liver disease, cirrhosis and hepatic encephalopathy via the gut-liver-brain axis, and the focus is to clarify the potential mechanisms and treatment of digestive diseases based on the further understanding of the microbiota-gut-liver-brain axis.Jian-Hong Ding Zhe Jin Xiao-Xu Yang Jun Lou Wei-Xi Shan Yan-Xia Hu Qian Du Qiu-Shi Liao Rui Xie Jing-Yu Xu 2020World Journal of Gastroenterology2020,26,40:13

8Removal of arsenate with hydrous ferric oxide coprecipitation: Effect of humic acid显示文摘Insights from the adverse effect of humic acid(HA) on arsenate removal with hydrous ferric oxide(HFO) coprecipitation can further our understanding of the fate of As(V) in water treatment process. The motivation of our study is to explore the competitive adsorption mechanisms of humic acid and As(V) on HFO on the molecular scale. Multiple complementary techniques were used including macroscopic adsorption experiments, surface enhanced Raman scattering(SERS), extended X-ray absorption fine structure(EXAFS) spectroscopy, flow-cell attenuated total reflectance Fourier transform infrared(ATR-FTIR) measurement, and charge distribution multisite complexation(CDMUSIC) modeling. The As(V) removal efficiency was reduced from over 95% to about 10% with the increasing HA concentration to 25 times of As(V) mass concentration. The SERS analysis excluded the HA-As(V) complex formation. The EXAFS results indicate that As(V) formed bidentate binuclear surface complexes in the presence of HA as evidenced by an As-Fe distance of 3.26–3.31 ?. The in situ ATR-FTIR measurements show that As(V) replaces surface hydroxyl groups and forms innersphere complex. High concentrations of HA may physically block the surface sites and inhibit the As(V) access. The adsorption of As(V) and HA decreased the point of zero charge of HFO from 7.8 to 5.8 and 6.3, respectively. The CD-MUSIC model described the zeta potential curves and adsorption edges of As(V) and HA reasonably well.Jingjing Du Chuanyong Jing Jinming Duan Yongli Zhang Shan Hu 2014Journal of Environmental Sciences2014,26,2:12
9The intra-neuroendoscopic technique: a new method for rapid removal of acute severe intraventricular hematoma显示文摘The mortality rate of acute severe intraventricular hematoma is extremely high, and the rate of disability in survivors is high. Intraventricular hematoma has always been a difficult problem for clinical treatment. Although minimally invasive endoscopic hematoma evacuation is widely used to treat this disease, the technique still has room for improvement. Equipment for the intra-neuroendoscopic technique(INET) consists of two of our patented inventions: a transparent sheath(Patent No. ZL 200820046232.0) and a hematoma aspirator(Patent No. ZL 201520248717.8). This study explored the safety and efficacy of INET by comparing it with extraventricular drainage in combination with urokinase thrombolytic therapy. This trial recruited 65 patients with severe intraventricular hemorrhage, including 35(19 men and 16 women, aged 53.2 ± 8.7 years) in the INET group and 30(17 men and 13 women, aged 51.5 ± 7.9 years) in the control group(extraventricular drainage plus urokinase thrombolytic therapy). Our results showed that compared with the control group, the INET group exhibited lower intraventricular hemorrhage volumes, shorter intensive care-unit monitoring and ventricular drainage-tube placement times, and fewer incidences of intracranial infection, secondary bleeding, and mortality. Thus, the prognosis of survivors had improved remarkably. These findings indicate that INET is a safe and efficient new method for treating severe intraventricular hematoma. This trial was registered with Clinical Trials.gov(NCT02515903).Bo Du Ai-Jun Shan Yu-Juan Zhang Jin Wang Kai-Wen Peng Xian-Liang Zhong Yu-Ping Peng 2018Neural Regeneration Research2018,13,6:10
10Inlet Recirculation Influence to the Flow Structure of Centrifugal Impeller显示文摘Inlet recirculation is proved as an effective way for centrifugal compressor surge margin extension,and is successively used in some engineering applications.Unfortunately its working mechanism is still not being well understood,which leads to redesigning of inlet recirculation mostly by experience.Also,most study about inlet recirculation is steady to date.It is necessary to study surge margin extension mechanism about inlet recirculation.To expose the mechanism in detail,steady and unsteady numerical simulations were performed on a centrifugal compressor with and without inlet recirculation.The results showed that,with inlet recirculation,the inlet axial velocity is augmented,relative Mach number around blade tip leading edge area is significantly reduced and so is the flow angle.As the flow angle decreased,the incidence angle reduced which greatly improves the flow field inside the impeller.Moreover,inlet recirculation changes the blade loading around blade tip and restrains the flow separation on the blade suction side at the leading edge area.The unsteady results of static pressure around blade surface,entropy at inlet crossflow section and vorticity distributions at near tip span surface indicated that,at near stall condition,strong fluctuation exists in the vicinity of tip area due to the interaction between tip leakage flow and core flow.By inlet recirculation these strong flow fluctuations are eliminated so the flow stability is greatly enhanced.All these improvements mentioned above are the reason for inlet recirculation delays compressor stall.This research reveals the surge margin extension reason of inlet recirculation from an unsteady flow viewpoint and provides important reference for inlet recirculation structure design.YANG Ce CHEN Shan LI Du YANG Changmao WANG Yidi 2010Chinese Journal of Mechanical Engineering2010,23,5:10
11Comparison of Electroacupuncture and Body Acupuncture on Gastrocnemius Muscle Tone in Children with Spastic Cerebral Palsy: A Single Blinded, Randomized Controlled Pilot Trial显示文摘Objective:To compare the immediate effects of electroacupuncture(EA)and body acupuncture(BA)on gastrocnemius muscle tone in children with spastic cerebral palsy(CP).Methods:Children with spastic CP,age from 24 to 60 months,who all received rehabilitation treatment in the Department of Developmental and Behavioral Pediatrics,the First Hospital of Jilin University from April 2016 to May 2017 were enrolled in this trial and assigned to EA group and BA group through a random number table.Both EA and BA therapies were performed on acupoints of Zusanli(ST 36),Shangjuxu(ST 37),Sanyinjiao(SP 6),and Xuanzhong(GB 39)for 30 min once.The root mean square(RMS),integrated electromyogram(iEMG)of the gastrocnemius of surface electromyography(sEMG),and Modified Tardieu Scale(MTS)of the two groups were evaluated before and after treatment.All adverse events were accurately recorded.Results:Thirty-six children with spastic CP completed the study(18 cases and 32 legs in the EA group;18 cases and 31 legs in the BA group).There was no significant difference in RMS,iEMG and MTS between the two groups before treatment(P>0.05).After treatment,compared with before treatment,RMS and iEMG significantly reduced and MTS(R2–R1)significantly increased in both EA and BA groups(P<0.05),and EA was more effective than BA in RMS and MTS(P<0.05).However,the iEMG between the two groups were not statistically significant after treatment(P>0.05).There was no serious adverse event during this clinical trial.Conclusion:Both EA and BA could significantly relieve the gastrocnemius muscle tone in spastic CP,and EA was more effective than BA.WANG Li-li SHAN Ling DU Lin ZHANG Yu JIA Fei-yong 2020Chinese Journal of Integrative Medicine2020,26,1:10
12Lamivudine prophylaxis of liver allograft HBV reinfection in HBV related cirrhotic patients after liver transplantation显示文摘BACKGROUND: Liver allograft hepatitis B virus (HBV) reinfection and hepatitis B (HB) recurrence jeopardize the long-term survival of recipient and liver allograft. Lamivu- dine has been referred as a novel antiviral agent against HBV in HBV cirrhotic patients even in liver transplantation setting. We assessed the prophylatic effect of lamivudine on liver allograft HBV reinfection and clarified the dynamic changes of HBV markers in HBV related decompensated liver cirrhosis after liver transplantation. METHODS: Twenty-five recipients were divided into three groups: HBV active replication group (15 recipients), HBV inactive replication group (7), and control group (3). 100 mg/d lamivudine was administered preoperatively except in the control group. The HBV markers of serial sera and liver biopsy samples of the 25 recipients were evaluated re- gularly with enzyme-linked radioimmunoassay, HBV DNA fluorecent quantitative assay, immunohistochemical stain- ing , labelled streptavidin biotin ( LSAB) and digoxin la- belled HBV DNA hybridization in situ. The dynamic alter- nation of HBV markers under lamivudine prophylaxis was observed. RESULTS: In the HBV active replication group who had received lamivudine 2 weeks before liver transplantation, serum HBV DNA positive converted to negative by 80%. HBsAg of all recipients disappeared after liver transplanta- tion , but corresponding antibodies of HBV appeared within one week after the operation. HBsAb 9/15, HBcAb 13/15 and HBeAb 11/15 appeared and subsided gradually within 24 weeks. HBV DNA in sera was kept negative; HBsAg, HBcAg and HBV DNA hybridization in situ of liver biopsy samples remained negative after use of lamivudine. Ten of the 15 recipients showed clearance of HBV, and per se HBV markers were undetectable both in serum and liver bi- opsy samples between 12 to 44 weeks (24 weeks on ave- rage). The 1-, 2-year survival rates were 83% in this group. Two of the 15 recipients developed HBV allograft reinfection or recurrence of hepatitis 2 years after lamivudi- ne monoprophylaxis (2/15, 13.3%). In the HBV inactive replication group, the outcome was similar to that of the HBV active group. The HBV antibody frequency was HBs- Ab 4/7, HBcAb 6/7, and HBeAb 2/7. Three of 7 recipients showed HBV clearance both in sera and liver biopsy sam- ples , whereas in the control group all 3 recipients developed HBV allograft reinfection and recurrent hepatitis 8, 10, 12 months postoperatively; one of them died of fibrosing cho- lestatic hepatitis, and the remaining 2 recovered after addi- tional lamivudine therapy. The overall allograft reinfection rate was 9.1% (2/22) and the overall 1-, 2-year survival rates were 87%) in the lamivudine prophylaxis group. CONCLUSIONS: Lamivudine prophylaxis can prevent ef- fectively liver allograft from HBV reinfection in patients with HBV-related decompensated liver cirrhosis even in HBV active replication recipient after liver transplantation. Its long-term outcome remains to be studied.Shi-Chun Lu, Lu-Nan Yan, Bo Li, Tian-Fu Wen, Ji-Chun Zhao, Nan-Sheng Cheng, Chong Liu, Jun Liu, Xiao-Bo Wang, Xiao-Dong Li, Shan Qin, Lian-Shan Zhao, Bin-Jun Lei and Xiu-Hui Zhang Chengdu, China Department of Surgery Viral Hepa- titis Research Center Department of Pathology , West China Hospital, Sichuan University, Cheng- du 610041 , China 2004Hepatobiliary & Pancreatic Diseases International2004,3,1:9
13Connecting the P300 to the diagnosis and prognosis of unconscious patients显示文摘The residual consciousness of unconscious patients can be detected by studying the P300, a wave among event-related potentials. Previous studies have applied tones, the subject's name and other names as stimuli. However, the results were not satisfactory. In this study, we changed the constituent order of subjects' two-character names to create derived names. The subject's derived names, together with tones and their own names, were used as auditory stimuli in event-related potential experiments. Healthy controls and unconscious patients were included in this study and made to listen to these auditory stimuli. In the two paradigms, a sine tone followed by the subject's own name and the subject's derived name followed by the subject's own name were used as standard and deviant stimuli, respectively. The results showed that all healthy controls had the P300 using both paradigms, and that the P300 in the second paradigm had a longer latency and two peaks. All minimally conscious state patients had the P300 in the first paradigm and the majority of them had the P300 in the second paradigm. Most vegetative state patients had no P300. Patients who showed the P300 in the two paradigms had more residual consciousness, and patients with the two-peak P300 had a higher probability of awakening within a short time. Our experimental findings suggest that the P300 event-related potential could reflect the conscious state of unconscious patients.Ran Li Wei-qun Song Ju-bao Du Su Huo Gui-xiang Shan 2015Neural Regeneration Research2015,10,3:9
14Selective catalytic reduction of NO_(x) with NH_(3):opportunities and challenges of Cu-based small-pore zeolites显示文摘Zeolites,as efficient and stable catalysts,are widely used in the environmental catalysis field.Typically,Cu-SSZ-13 with small-pore structure shows excellent catalytic activity for selective catalytic reduction of NO_(x) with ammonia(NH_(3)-SCR)as well as high hydrothermal stability.This review summarizes major advances in Cu-SSZ-13 applied to the NH_(3)-SCR reaction,including the state of copper species,standard and fast SCR reaction mechanism,hydrothermal deactivation mechanism,poisoning resistance and synthetic methodology.The review gives a valuable summary of new insights into the matching between SCR catalyst design principles and the characteristics of Cu^(2+)-exchanged zeolitic catalysts,highlighting the significant opportunity presented by zeolite-based catalysts.Principles for designing zeolites with excellent NH_(3)-SCR performance and hydrothermal stability are proposed.On the basis of these principles,more hydrothermally stable Cu-AEI and Cu-LTA zeolites are elaborated as well as other alternative zeolites applied to NH_(3)-SCR.Finally,we call attention to the challenges facing Cu-based small-pore zeolites that still need to be addressed.Yulong Shan Jinpeng Du Yan Zhang Wenpo Shan Xiaoyan Shi Yunbo Yu Runduo Zhang Xiangju Meng Feng-Shou Xiao Hong He 2021National Science Review2021,8,10:9
15Comparative genetic analysis of Arabidopsis purple acid phosphatases AtPAP10, AtPAP12, and AtPAP26 provides new insights into their roles in plant adaptation to phosphate deprivation显示文摘Induction and secretion of acid phosphatases(APases) is thought to be an adaptive mechanism that helps plants survive and grow under phosphate(Pi) deprivation. In Arabidopsis, there are 29 purple acid phosphatase(AtPAP)genes. To systematically investigate the roles of different AtPAPs, we first identified knockout or knock‐down T‐DNA lines for all 29 AtPAP genes. Using these atpap mutants combined with in‐gel and quantitative APase enzyme assays,we demonstrated that AtPAP12 and AtPAP26 are two major intracellular and secreted APases in Arabidopsis while AtPAP10is mainly a secreted APase. On Pi‐deficient(P) medium or Pmedium supplemented with the organophosphates ADP and fructose‐6‐phosphate(Fru‐6‐P), growth of atpap10 was significantly reduced whereas growth of atpap12 was only moderately reduced, and growth of atpap26 was nearly equal to that of the wild type(WT). Overexpression of the AtPAP12 or AtPAP26 gene, however, caused plants to grow better on Por P medium supplemented with ADP or Fru‐6‐P. Interestingly, Pi levels are essentially the same for the WT and overexpressing lines, although these two types of plants have significantly different growth phenotypes. These results suggest that the APases may have other roles besides enhancing internal Pi recycling or releasing Pi from external organophosphates for plant uptake.Liangsheng Wang Shan Lu Ye Zhang Zheng Li Xiaoqiu Du Dong Liu 2014Journal of Integrative Plant Biology2014,56,3:9
16Concurrent chemoradiotherapy with weekly docetaxel versus cisplatin in the treatment of locoregionally advanced nasopharyngeal carcinoma:a propensity score-matched analysis显示文摘Background:Promising efficacy and manageable toxicity of docetaxel-based concurrent chemoradiotherapy(CCRT)were reported in head and neck cancer.In addition,the effect of CCRT in combination with cisplatin and/or 5-fluorouracil on both locoregionally advanced and metastatic/recurrent nasopharyngeal carcinoma(NPC)was verified.However,CCRT with docetaxel for locoregionally advanced NPC are not well studied.This study aimed to compare effectiveness and toxicities of CCRT with weekly docetaxel versus tri-weekly cisplatin for locoregionally advanced NPC.Methods:Clinical data of patients with locoregionally advanced NPC newly diagnosed between January 2010 and December 2014 receiving CCRT with either weekly docetaxel(15 mg/m2)or tri-weekly cisplatin(80-100 mg/m2)were reviewed.Propensity score matching at a 1:1 ratio was performed to balance baseline characteristics.Adverse events and survival were compared between the two groups.Results:A total of 962 patients were included as the whole cohort,and 448 patients were matched and were regarded as the matched cohort.The median follow-up duration was 48 months for the whole cohort.The 3-year nodal recurrence-free survival rate was significantly increased for patients treated with docetaxel in both the whole(hazard ratio[HR]=0.37,95%confidence interval[CI]0.19-0.72,P=0.030)and matched cohorts(HR=0.33,95%CI 0.14-0.79,P=0.023).However,no significant differences were observed in overall survival,local recurrence-free survival,and distant metastasis-free survival between the two groups in both cohorts.Significantly higher rates of grade 3 radiodermatitis(6.7%vs.1.8%,P=0.001),mucositis(74.5%vs.37.9%,P<0.001),and leucopenia(2.2%vs.11.6%,P<0.001)were observed in the docetaxel group,but any grade of renal injury(1.8%vs.15.1%,P<0.001),vomiting(18.8%vs.88.3%,P<0.001),and ALT elevation(19.2%vs.31.3%,P=0.027)were more common in the cisplatin group.Conclusions:CCRT with weekly low-dose docetaxel is an effective and tolerable therapeutic regimen for locally advanced NPC.It provides a survival benefit mainly by improving the control of regional lymph node metastases,especially for patients with low pretreatment EBV DNA levels.Jun-Fang Liao Qun Zhang Xiao-Jing Du Mei Lan Shan Liu Yun-Fei Xia Xiu-Yu Cai Wei Luo 2019Cancer Communications2019,39,1:9
17Clinical characteristics and survival of 5283 esophageal cancer patients: A multicenter study from eighteen hospitals across six regions in China显示文摘Objective:This study aimed to investigate the potential determining epidemiological and clinical risk factors affecting the survival of esophageal cancer(EC)patients across multiple hospitals in China.Methods:This was a multicenter study comprising of newly diagnosed EC cases from Beijing,Hebei,Henan,Hubei,Zhejiang,and Guangdong Province of China.Their baseline characteristics and treatment methods data were collected from their medical records.The EpiData software was used for data quality control.The Kaplan-Meier method was used to estimate their overall survival(OS),and the Cox’s proportional hazard regression model was used to estimate hazard ratios(HR)and 95%confidence interval(CI).Results:The 3-and 5-year OS rates of the 5283 investigated EC patients were 49.98%and 39.07%,respectively.Their median survival was 36.00 months.The median survival time of females was longer than that of males(females vs.males:45.00 vs.33.00,P<0.001).The 5-year OS rate of patients who never-smoked was higher than that of smokers(never-smokers vs smokers:40.73%vs.37.84%,P=0.001).There was no significant difference in the 5-year OS rate between drinkers and never-drinkers(drinkers vs never-drinkers:34.22%vs.29.65%,P=0.330).In multivariate analysis,pathological stage(stage II:HR=1.80,95%CI=1.40-2.31;stage III:HR=2.62,95%CI=2.06-3.34;stage IV:HR=3.90,95%CI=2.98-5.09),poor differentiation/undifferentiated(HR=1.34,95%CI=1.11-1.63),not married status(HR=2.45,95%CI=1.49-4.04),production and service personnel(HR=1.36,95%CI=1.01-1.83)and farming/fishing(HR=1.40,95%CI=1.12-1.76)were independent prognostic risk factors for poor EC survival.Tumors in the thoracic or abdominal part of the esophagus,female and family history of any cancer were independent factors predictive of a good EC OS.Conclusion:Gender,marital status,occupation,family history of any cancer,tumor topographical site,differentiation status,and pathological stage were associated with the survival rate of EC.This study reveals important clinical characteristics of esophageal cancer patients in China and provides helpful information for their clinical management and surveillance.Yutong He Di Liang Lingbin Du Tiantian Guo Yanyu Liu Xibin Sun Ning Wang Min Zhang Kuangrong Wei Baoen Shan Wanqing Chen 2020Cancer Communications2020,40,10:8

19Bph30confers resistance to brown planthopperby fortifying sclerenchyma in rice leaf sheaths显示文摘Phloem-feeding insects cause massive losses in agriculture and horticulture.Host plant resistance to phloem-feeding insects is often mediated by changes in phloem composition,which deter insect settling and feeding and decrease viability.Here,we report that rice plant resistance to the phloem-feeding brown planthopper(BPH)is associated with fortification of the sclerenchyma tissue,which is located just beneath the epidermis and a cell layer or two away from the vascular bundle in the rice leaf sheath.We found that BPHs prefer to feed on the smooth and soft region on the surface of rice leaf sheaths called the long-cell block.We identified Bph30 as a rice BPH resistance gene that prevents BPH stylets from reaching the phloem due to the fortified sclerenchyma.Bph30 is strongly expressed in sclerenchyma cells and enhances cellulose and hemicellulose synthesis,making the cell walls stiffer and sclerenchyma thicker.The structurally fortified sclerenchyma is a formidable barrier preventing BPH stylets from penetrating the leaf sheath tissues and arriving at the phloem to feed.Bph30 belongs to a novel gene family,encoding a protein with two leucine-rich domains.Another member of the family,Bph40,also conferred resistance to BPH.Collectively,the fortified sclerenchyma-mediated resistance mechanism revealed in this study expands our understanding of plant-insect interactions and opens a new path for controlling planthoppers in rice.Shaojie Shi Huiying Wang Lingyun Nie Di Tan Cong Zhou Qian Zhang YiLi Bo Du Jianping Guo Jin Huang DiWu Xiaohong Zheng Wei Guan Junhan Shan Lili Zhu Rongzhi Chen Longjian Xue Linda L.Walling Guangcun He 2021Molecular Plant2021,14,10:7
20Direct observation of ultrafast plasmonic hot electron transfer in the strong coupling regime显示文摘Achieving strong coupling between plasmonic oscillators can significantly modulate their intrinsic optical properties.Here,we report the direct observation of ultrafast plasmonic hot electron transfer from an Au grating array to an MoS_(2) monolayer in the strong coupling regime between localized surface plasmons(LSPs)and surface plasmon polaritons(SPPs).By means of femtosecond pump-probe spectroscopy,the measured hot electron transfer time is approximately 40 fs with a maximum external quantum yield of 1.65%.Our results suggest that strong coupling between LSPs and SPPs has synergetic effects on the generation of plasmonic hot carriers,where SPPs with a unique nonradiative feature can act as an‘energy recycle bin’to reuse the radiative energy of LSPs and contribute to hot carrier generation.Coherent energy exchange between plasmonic modes in the strong coupling regime can further enhance the vertical electric field and promote the transfer of hot electrons between the Au grating and the MoS_(2) monolayer.Our proposed plasmonic strong coupling configuration overcomes the challenge associated with utilizing hot carriers and is instructive in terms of improving the performance of plasmonic opto-electronic devices.Hangyong Shan Ying Yu Xingli Wang Yang Luo Shuai Zu Bowen Du Tianyang Han Bowen Li Yu Li Jiarui Wu Feng Lin Kebin Shi Beng Kang Tay Zheng Liu Xing Zhu Zheyu Fang 2019Light(Science & Applications)2019,8,1:7
