1On-chip ultrasensitive and rapid hydrogen sensing based on plasmon-induced hot electron-molecule interaction显示文摘Hydrogen energy is a zero-carbon replacement for fossil fuels.However,hydrogen is highly flammable and explosive hence timely sensitive leak detection is crucial.Existing optical sensing techniques rely on complex instruments,while electrical sensing techniques usually operate at high temperatures and biasing condition.In this paper an on-chip plasmonic-catalytic hydrogen sensing concept with a concentration detection limit down to 1 ppm is presented that is based on a metal-insulator-semiconductor(MIS)nanojunction operating at room temperature and zero bias.The sensing signal of the device was enhanced by three orders of magnitude at a one-order of magnitude higher response speed compared to alternative non-plasmonic devices.The excellent performance is attributed to the hydrogen induced interfacial dipole charge layer and the associated plasmonic hot electron modulated photoelectric response.Excellent agreements were achieved between experiment and theoretical calculations based on a quantum tunneling model.Such an on-chip combination of plasmonic optics,photoelectric detection and photocatalysis offers promising strategies for next-generation optical gas sensors that require high sensitivity,low time delay,low cost,high portability and flexibility.Long Wen Zhiwei Sun Qilin Zheng Xianghong Nan Zaizhu Lou Zhong Liu David R.S.Cumming Baojun Li Qin Chen 2023Light(Science & Applications)2023,12,4:1
2Nanostructured materials with localized surface plasmon resonance for photocatalysis显示文摘Localized surface plasmon resonance (LSPR) enhanced photocatalysis has fascinated much interest and considerable efforts have been devoted toward the development of plasmonic photocatalysts. In the past decades, noble metal nanoparticles (Au and Ag) with LSPR feature have found wide applications in solar energy conversion. Numerous metal-based photocatalysts have been proposed including metal/semiconductor heterostructures and plasmonic bimetallic or multimetallic nanostructures. However, high cost and scarce reserve of noble metals largely limit their further practical use, which drives the focus gradually shift to low-cost and abundant nonmetallic nanostructures. Recently, various heavily doped semiconductors (such as WO_(3-x), MoO_(3-x), Cu_(2-x)S, TiN) have emerged as potential alternatives to costly noble metals for efficient photocatalysis due to their strong LSPR property in visible-near infrared region. This review starts with a brief introduction to LSPR property and LSPR-enhanced photocatalysis, the following highlights recent advances of plasmonic photocatalysts from noble metal to semiconductor-based plasmonic nanostructures. Their synthesis methods and promising applicability in plasmon-driven photocatalytic reactions such as water splitting, CO_(2) reduction and pollution decomposition are also summarized in details. This review is expected to give guidelines for exploring more efficient plasmonic systems and provide a perspective on development of plasmonic photocatalysis.Juan Li Zaizhu Lou Baojun Li 2022Chinese Chemical Letters2022,33,3:1

10Reading comprehension without phonological mediation:Further evidence from a Chinese aphasic individual显示文摘An important issue in visual word comprehension literature is whether or not semantic access is mediated by phonological processing. In this paper, we present a Chinese individual, YGA, who provides converging evidence to directly address this issue. YGA has sustained damage to the left posterior superior and middle temporal lobe, and shows difficulty in orally name pictures and reading printed words aloud. He makes phonological errors on these tasks and also semantic errors on picture naming, indicating a deficit at accessing the phonological representations for output. However, he is intact at understanding the meaning of visually presented words. Such a profile challenges the hypothesis that semantic access in reading is phonologically mediated and provides further evidence for the universal principle of direct semantic access in reading.HAN ZaiZhu & Bi YanChao State Key Laboratory of Cognitive Neuroscience and Learning, Beijing Normal University, Beijing 100875, China 2009Science China(Life Sciences)2009,52,5:1
11Light-induced thermal convection for collection and removal of carbon nanotubes显示文摘Carbon nanotubes(CNTs)have exhibited immense potential for applications in biology and medicine,and once their intended purpose is fulfilled,the elimination of residual CNTs is essential to avoid negative effects.In this study,we demonstrated the effective collection and simple removal of CNTs dispersed in a suspension via thermal convection.First,a tapered fiber tip with a cone angle and end diameter of 10°and 3μm,respectively,was fabricated via a heating and pulling method.Further,a laser beam with a power and wavelength of 100 mW and 1.55^m,respectively,was launched into the tapered fiber tip,which was placed in a CNT suspension,resulting in the formation of a microbubble on the fiber tip.The temperature gradient on the microbubble and suspension surface induced thermal convection in the suspension,which resulted in the accumulation of CNTs on the fiber tip.The experimentally formed CNT cluster possessed a circular top surface with a diameter of 87 nm and an arched cross-section with a height of 19μm.Furthermore,this CNT cluster was firmly attached to the fiber tip.Therefore,the removal of CNT clusters can be realized by simply removing the fiber tip from the suspension.Moreover,we simulated the thermal convection that caused CNT aggregation.The obtained results indicate that convection near the fiber tip flows toward it,which pushes the CNTs toward the fiber tip and enables their attachment to it.Further,the flow velocity is symmetrically distributed as a Gaussian function,which results in the formation of a circular top surface and arched cross-sectional profile for the CNT cluster.Our method may be applied in biomedicine for the collection and removal of nano-drug residues.Xianguang Yang Rui Xu Long Wen Zaizhu Lou Qin Chen Baojun Li 2022Fundamental Research2022,2,1:0
12Effects of hand clasping and arm folding on academic performance显示文摘BACKGROUND:Similar to handedness, hand clasping and arm folding are also lateral preferences. Previous studies showed a variation frequency for hand clasping and arm folding among different populations. OBJECTIVE: To investigate the relationship between patterns of lateral preferences (hand clasping or arm folding) and academic performance of middle school students. DESIGN, TIME AND SETTINGS: Cross-sectional investigation. The data were collected in the Beijing Zhongguancun High School in Beijing in May 2007. Data analysis was performed in the State Key Laboratory of Cognitive Neuroscience and Learning, Beijing Normal University during June to July 2007. PARTICIPANTS: A total of 102 senior-grade students from Beijing Zhongguancun High School, including 58 males and 44 females, were selected for this study. METHODS: Different forms of hand clasping and arm folding were recorded. More specifically, hand clasping was either right-thumb-top or left-thumb-top, and arm folding was either right-arm-top or left-arm-top. Students with congruent preference used right-thumb-top-right-arm-top or left-thumb-top-left-arm-top, and incongruent preference was displayed by right-thumb-top-left-arm-top or left-thumb-top-right-arm-top. Academic performances were collected from midterm exams in six subjects (Chinese, Mathematics, English, Physics, Chemistry, and Biology), with a total points = 100 for each. A three-way (hand clasping, arm folding, and sex) ANOVA was performed to determine the effect on academic performances. MAIN OUTCOME MEASURES: The relationship between hand clasping, arm folding, sex, and academic performance of students. RESULTS: (1) There was no significant difference in distribution frequency between right-thumb-top and left-thumb-top (P > 0.05), or between right-arm-top and left-arm-top (P > 0.05). The distribution frequency difference between boys and girls was not significant for any subtype (P > 0.05). (2) hand clasping had no significant main effect on any of the six subjects (P > 0.05). The right-arm-top students received significantly higher points in Chinese, Physics, Chemistry, and Biology, compared with the left-arm-top students (P < 0.05). A significant sexual difference was detected in academic performance in Chinese and English; girls had higher scores than the boys (P < 0.05). The students with congruent preference scored higher in English, compared with those with incongruent preference (P < 0.05). CONCLUSION: The arm folding form of lateral preference had a significant effect on academic performance of middle school students, implying that this human laterality index is of great functional importance.Zhenxiang Zang Zaizhu Han Yufeng Zang 2008Neural Regeneration Research2008,3,8:0
