| 1 | Characteristics of typhoon disturbed gaps in an old-growth tropical montane rainforest in Hainan Island, China显示文摘Disturbances that create gaps can shape the structure and function of forests. However, such disturbance regimes in Asian tropical montane rainforests remain largely unquantified. Least studied are typhoon disturbances that are attributable to climate change. We investigated gap characteristics in terms of size, age, and gapmaker to quantify the gap disturbance regimes in an intact old-growth tropical montane rainforest on Hainan Island,China. The intensity of typhoons has increased since 1949,and typhoon winds blow mostly(45.5%) from the northeast corner of Hainan Island, resulting in a higher frequency of gaps in the northeast. A total of 221 gap-makers(trees that fell to create canopy gaps) and 53 gaps were observed in a 3.16 ha old-growth rainforest. Most canopy gaps(85%)were <200 m^2. The average size of canopy gaps was smaller in the rainforest than in other tropical forests, while the average size of expanded gaps was similar to those in other tropical forests. The maximum age of gaps was 23.5 years indicating that gaps had more rapid turnover than other parts of tropical forests. The frequency distribution of gap-makers followed a lognormal distribution with a distinctive peak at three gap-makers, which was different from the inverse J-shaped curve typical of other tropical forests. Gaps were recorded mainly on slopes between 20° and 35° and wood density of gap-makers was between 0.6 and 0.7 g cm^(-3). Our results suggest that small-scale disturbance was the dominant agent of gap formation in this old-growth rainforest that is subject to increasing typhoon disturbances. | Huai Yang Shirong Liu Kunfang Cao Jingxin Wang Yide Li Han Xu | 2017 | Journal of Forestry Research2017，28，6： | 3 |

| 3 | Highly safe and ionothermal synthesis of Ti3C2 MXene with expanded interlayer spacing for enhanced lithium storage显示文摘MXene is a rising star of two-dimensional(2D)materials for energy relative applications,however,the traditional synthesis of MXene etched by hazard HF acid or LiF+HCl mixed solution is highly dangerous with the risk of splashing or pouring liquid solutions.In this work,we developed a water-free ionothermal synthesis of 2D Ti3C2 MXene via etching pristine Ti3AlC2 MAX in low-cost choline chloride and oxalic acid based deep eutectic solvents(DES)with the presence of NH4F,thus it was highly safe and convenient to operate solid precursor and product materials at room temperature.Benefited from the low vapor pressure and solvating properties of DES,the prepared Ti3C2(denoted as DES-Ti3C2)possessed a high purity up to 98% compared with 95% for HF etched Ti3C2(denoted as HF-Ti3C2).Notably,an expanded interlayer spacing of 1.35 nm could be achieved due to the intercalation of choline cations in DES-Ti3C2,larger than that of HF-Ti3C2(0.98 nm).As a result,the DES-Ti3C2 anodes exhibited enhanced lithium storage performance,such as high reversible capacity of 208 m Ah g-1at 0.5 A g-1,and long cycle life over 400 times,outperforming most reported pure MXene anodes.The ionothermal synthesis of MXene developed here may pave a new way to safely prepare other MXene for various energy relating applications. | Junbiao Wu Yu Wang Yaopeng Zhang Hao Meng Yan Xu Yide Han Zhuopeng Wang Yanfeng Dong Xia Zhang | 2020 | Journal of Energy Chemistry2020，29，8： | 1 |

| 8 | YSO coded aperture camera based on depth of interaction for location correction显示文摘Purpose Coded aperture imaging was a widely used imaging method for radiation sources.However,the traditional gamma camera based on two-dimensional projection information for coded aperture imaging ignored the influence of the interaction depth of particles and detectors on the projection information,which reduced the imaging quality of the camera to some extent.Therefore,a method of correcting the coded gamma camera based on the interaction depth of particles and detectors is proposed to improve the location accuracy of detectors.Methods The camera developed in this work uses a 7×7 YSO crystal array coupled with two 7×7 Si-PM arrays.The crystal is evenly divided into 11 parts in the depth direction,with a voxel size of 3×3×3 mm3.The coded mask is a 13×13 array,which is a mosaic of two cycles of 7×7 modified uniformly redundant array mask.The depth resolution of the detector is obtained via the subsurface laser engraving dual-end readout method.After obtaining the three-dimensional position information of the interaction point the projection information obtained by the detector is layered,and the image is reconstructed.According to the spatial position information of the detector and the coded mask,the corresponding field of view of each layer of the detector is calculated,and the reconstructed image of each layer is amplified and superimposed according to the ratio of the field of view to obtain the reconstructed image combined with the depth information.Results and conclusion According to Monte Carlo simulation and radiation source imaging experiment results,this method can effectively improve the positioning ability of the detector.For the experimental scenario mentioned in the paper,the location accuracy can be improved by up to 1.54°. | Yiding Han Xiaopan Jiang Haohui Tang Xiuzuo Liang Xuanhou Hu Xianchao Huang Zhiming Zhang Lei Shuai Jing Guo Long Wei | 2023 | Radiation Detection Technology and Methods2023，7，4： | 0 |
| 9 | Nanomeshed Si nanomembranes显示文摘One of the main challenges in stretchable electronics is to achieve high-performance stretchable semiconductors. Here, weintroduce an innovative concept of nanomeshed semiconductor nanomembrane which can be regarded almost as intrinsicallystretchable to conventional microelectronic layouts. By making a silicon film into homogeneous nanomeshes with spring-like nanotraces, we demonstrated a high electron mobility of 50 cm^(2)/V·s, and moderate stretchability with a one-time strain of 25% andcyclic strain of 14% after stretching for 1000 cycles, further improvable with optimized nanomesh designs. A simple analytic modelcovering both fractional material and trace sidewall surfaces well predicted the transport properties of the normally on siliconnanomesh transistors, enabling future design and optimizations. Besides potential applications in stretchable electronics, thissemiconductor nanomesh concept provides a new platform for materials engineering and is expected to yield a new family ofstretchable inorganic materials having tunable electronic and optoelectronic properties with customized nanostructures. | Xun Han Kyung Jin Seo Yi Qiang Zeping Li Sandra Vinnikova Yiding Zhong Xuanyi Zhao Peijie Hao Shuodao Wang Hui Fang | 2019 | npj Flexible Electronics2019，3，1： | 0 |
| 10 | Experiment validation of the high stability of long-term transmitted gamma photon counting of a new CdZnTe semiconductor detector and its preliminary applications显示文摘Purpose To develop a detector system with high stability in counting the detection of transmitted gamma photons,which can be applied in the area of non-destructive testing.Method We used the cadmium zinc telluride(CZT)detector with single-polarity electrodes to substitute the traditional scintillator detector and front-end read-out electronics based on our self-designed low-noise charge-sensitive amplifier.Results and conclusion The energy resolution of 662 keV from 137Cs radioactive source was improved to 1.9%,and the relative standard deviation of different total counts of transmitted photons detected decreased to 0.05%when the counts were more than 5×107,which means the impact from the statisticalfluctuation of long-term gamma photons counting will not be a main obstacle to achieving high precision in the area of non-destructive testing.The preliminary experiment of inspecting the inner gaps in the metal rodsfilled with samples also proved to have good prospects for the CZT detector in non-destructive testing. | Chao Wang Yantao Liu Xiaopan Jiang Xianchao Huang Xiaoming Wang Yu Xiang Yiding Han Long Wei Zhiming Zhang | 2022 | Radiation Detection Technology and Methods2022，6，3： | 0 |
| 11 | Alpha particle detection with a planar CdZnTe detector and relative simulations显示文摘Purpose The performance of CZT inγ-ray and X-ray detection is growing rapidly in these years.However,there are only a few reports on its utilization inαparticle detection.Therefore,to study the properties of CZT for detection ofαparticle,a detection system has been manufactured,and a series of simulations have been done.Methods A 22×22×0.7mm^(3) planar CZT detector is deployed to detect theαparticles from a radiation source containing Am-241 and Pu-239,while COMSOL MultiPhysics and GEANT4 are employed in the simulation of charge collection and interaction betweenαparticles and CZT.Results An energy resolution of 1.47%FWHM at 5.486MeV and 1.32%at 5.157MeV has been achieved.A simulated spectrum has been created,and it is analogous to the one from experiment.Conclusion The experiment results show the potential of CZT inαdetection.The simulations are confirmed effective and will guide a better design of the detecting system. | Yu Xiang Xiaopan Jiang Chao Wang Fanhui Meng Yiding Han Xianchao Huang Long Wei | 2021 | Radiation Detection Technology and Methods2021，5，4： | 0 |
