| 1 | Characteristics of acoustic emission signals in damp cracking coal rocks显示文摘A uniaxial load experiment on coal rocks at different stress rates was carried out, based on the characteristics of acoustic emission (AE) signals in cracking coal rocks, decomposition, de-noising and reconstruction for the AE signals through wavelet packet transform for solving the current problems created by the presence of noise in AE signals and the existing problems in AE signal processing. The results show that the various characteristics of AE signals in coal rocks cracking under different situations can be clearly reflected, after the AE signals are de-noised by the wavelet packet. Compared to dry coal rocks, the number of AE occurrences in damp coal rocks was significantly reduced, as well as the average amplitude. The number of AE occurrences in damp and dry coal rocks clearly increased with increases in the loading rate, but the largest amplitude of the AE signals in damp coal rocks has been reduced. There is no clear evidence of change in dry coal rocks. | TANG Shoufeng, TONG Minming, HU Junli, HE Xinmin School of Information and Electrical Engineering, China University of Mining & Technology, Xuzhou 221008, China | 2010 | Mining Science and Technology2010，20，1： | 17 |
| 2 | All-solid-state BiVO4/ZnIn2S4 Z-scheme composite with efficient charge separations for improved visible light photocatalytic organics degradation显示文摘Constructing a Z-scheme is a significant approach to improve the separation of photogene rated carriers for effective organic pollutant degradation.Herein,a BiVO4/ZnIn2S4(BZ) Z-scheme composite was successfully synthesized,and applied to photodegrade methyl orange(MO) irradiated by a LED lamp.Anchoring the BiVO4 on the ZnIn2S4 nanoparticles promoted the separation of photogenerated electronholes and broadened the light response range.The detailed characterizations,including surface morphology,elements valence state,and photocurrent performance,demonstrated that the enhanced separation of photogenerated carriers was the pivotal reason for the enhanced photocatalysis reaction.Benefiting from the excellent photocatalytic characteristics,the 5% mass ratio of BZ composite presented the highest MO degradation rate of 0.00997 min^-1,which was 1.9 and 10.3 times greater than the virgin ZnIn2S4 and BiVO4,respectively.Furthermore,the BZ hybrid materials indicated a well photo-stability in the four recycling tests. | Deling Yuan Mengting Sun Shoufeng Tang Yating Zhang Zetao Wang Jinbang Qi Yandi Rao Qingrui Zhang | 2020 | Chinese Chemical Letters2020，31，2： | 5 |
| 3 | Ferric ion-ascorbic acid complex catalyzed calcium peroxide for organic wastewater treatment:Optimized by response surface method显示文摘Hydrogen peroxide(H_(2)O_(2))disproportionation,iron precipitation,and narrow pH range are the drawbacks of traditional Fenton process.To surmount these barriers,we proposed a ferric ion(Fe^(3+))-ascorbic acid(AA)complex catalyzed calcium peroxide(CaO_(2))Fenton-like system to remove organic dyes in water.This collaborative Fe^(3+)/AA/CaO_(2)system presented an obvious improvement in the methyl orange(MO)decolorization,and also effectively eliminated other dyes.Response surface method was employed to optimize the running parameters for this coupling process.Under the optimized arguments(2.76 mmol/L Fe^(3+),0.68 mmol/L AA,and 4 mmol/L CaO_(2)),the MO removal achieved 98.90%after 15 min at pH 6.50,which was close to the computed outcome of 99.30%.Furthermore,this Fenton-like system could perform well in a wide range of pH(3-11),and enhance the H_(2)O_(2)decomposition and Fe ions recycle.The scavenger experiment result indicated that hydroxyl radical,superoxide anion free radical,and singlet oxygen were acted on the dye elimination.Moreover,electron spin resonance analysis corroborated that the existences of these active species in the Fe^(3+)/AA/CaO_(2)system.This study could advance the development of Fenton-like technique in organic effluent disposal. | Deling Yuan Chen Zhang Shoufeng Tang Zetao Wang Qina Sun Xiaoyu Zhang Tifeng Jiao Qingrui Zhang | 2021 | Chinese Chemical Letters2021，32，11： | 2 |

| 5 | High Sensitive Methane Sensor With Temperature Compensation Based on Selectively Liquid-Infiltrated Photonic Crystal Fibers显示文摘A highly sensitive and temperature-compensated methane sensor based on a liquid-infiltrated photonic crystal fiber (PCF) is proposed. Two bigger holes near the core area are coated with a methane-sensitive compound film, and specific cladding air holes are infiltrated into the liquid material to form new defective channels. The proposed sensor can achieve accurate measurement of methane concentration through temperature compensation. The sensitivity can reach to 20.07nm/% with a high linearity as the methane concentration is within the range of 0%-3.5% by volume. The proposed methane sensor can not only improve the measurement accuracy, but also reduce the metrical difficulty and simplify the process. | Hai LIU Haoran WANG Wen ZHANG Cancan CHEN Qing WANG Yi DING Shoufeng TANG | 2019 | Photonic Sensors2019，9，3： | 1 |

| 9 | High-Sensitive Numerical Gas Detection Using LSPR Effect and Fano Resonance in a Slotted MDM Structure显示文摘A high-sensitive numerical measurement of methane based on the combined use of the localized surface plasmon resonance(LSPR)and Fano resonance in a slotted metal-dielectric-metal(MDM)periodic structure is numerically investigated.A groove is etched in an original MDM structure to excite the diploe mode at both sides of the groove,and the coherent coupling of two dipole modes is enhanced to realize a fast response,which is beneficial to gas-sensing.The influence of geometric parameters on the reflection spectra and methane sensitivity are analyzed to obtain optimal geometry.Moreover,an etching ring is introduced on the top metal to further raise the coupling area and coupling strength.The Fano resonance is subtly integrated into the optimized structure with asymmetry to achieve greater gas sensitivity.After the introduction of the Fano resonance,the field enhancement caused by the LSPR effect becomes greater and the methane sensitivity can reach up to 8.421 nm/%in numerical calculations,which increases 56.8%more than that of the original one.The combined use of the LSPR and Fano resonance in an optimized MDM structure provides an effective method for high-sensitive gas detection. | Hai LIU Benlei ZHAO Xu ZHANG Hancheng ZHANG Bo WU Shoufeng TANG | 2022 | Photonic Sensors2022，12，2： | 0 |
| 10 | Simultaneous structure and luminescence property control of barium carbonate nanocrystals through small amount of lanthanide doping显示文摘Rare earth doping has been widely applied in many functional nanomaterials with desirable properties and functions,which would have a significant effect on the growth process of the materials.However,the controlling strategy is limited into high concentration of lanthanide doping,which produces concentration quenching of the lanthanide ion luminescence with an increase in the Ln^(3+)concentration,resulting in lowering the fluorescence quantum yield of lanthanide ion.Herein,for the first time,we demonstrate simultaneous control of the structures and luminescence properties of BaCO_3nanocrystals via a small amount of Tb^(3+)doping strategy.In fact,Tb^(3+)would partially occupy Ba^(2+)sites,resulting in the changes to the structures of the BaCO_3nanocrystals,which is primarily determined by charge modulation,including the contributions from the surfaces of crystal nuclei and building blocks.These structurally modified nanocrystals exhibit tunable luminescence properties,thus emerging as potential candidates for photonic devices such as light-emitting diodes and color displays. | Jianmin Gu Zhenpan Bian Baipeng Yin Cuihong Jin Xin Liu Yahui Gao Jingxiao Wu Shoufeng Tang Faming Gao Yong Sheng Zhao | 2017 | Science Bulletin2017，62，18： | 0 |
