| 1 | Hydrothermal synthesis of monodisperse α-Fe_2O_3 hexagonal platelets显示文摘Uniformly sized α-Fe2O3 hexagonal platelets were synthesized by a hydrothermal process using Fe(OH)3 suspension and large amount of NaOH.The reaction products were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),selected area electron diffraction(SAED),and a vibrating sample magnetometer(VSM).The results show that the hexagonal platelets are fine,monodisperse and consisting of single-crystals.The magnetic hysteresis(M-H) curve of the samples measured at room temperature indicates that the α-Fe2O3 micro-platelets exhibit ferromagnetic behaviors with relatively low coercivity. | Dengfeng Peng Sadeh Beysen Qiang Li Yanfei Sun Linyu Yang | 2010 | Particuology2010，8，4： | 4 |
| 2 | Controlled fabrication, lasing behavior and excitonic recombination dynamics in single crystal CH3NH3PbBr3 perovskite cuboids显示文摘As a direct bandgap semiconductor, organic-inorganic lead halide perovskite (MAPbX3, MA = CH3NH3, X =Cl, Br, I) have been considered as promising materials for laser due to their excellent optoelectronic properties. The perovskite materials with ID and 2D shapes were widely prepared and studied for Fabry-Perot mode and whispering-gallery-mode (WGM) microcavities, but cuboid-shape is rarely reported. In this work, we successfully fabricated single crystal cuboid-shaped MAPbBr3 perovskite w让h different morphologies, named microcuboid-MAPbBr3 (M-MAPbBr3) and multi-step-MAPbBr3 (MSMAPbBr3), via solvothermal method. Furthermore, the as-prepared *crystals excitonic recombination lifetime under different pumping energy density was studied by time-resolved photoiuminescence (TRPL). Based on controllable morphology and remarkable lasing properties, these cuboid shaped single crystal perovskite could be a promising candidate for small laser, and other optoelectronic devices. | Fangtao Li Junfeng Lu Qinglin Zhang Dengfeng Peng Zheng Yang Qian Xu Caofeng Pan Anlian Pan Tianfeng Li Rongming Wang | 2019 | Science Bulletin2019，64，10： | 2 |

| 4 | Mechanoluminescent hybrids from a natural resource for energy-related applications显示文摘Mechanoluminescent(ML)materials that directly convert mechanical energy into photon emission have emerged as promising candidates for various applications.Despite the recent advances in the development of both novel and conventional ML materials,the limited access to ML materials that simultaneously have the attributes of high brightness,low cost,self-recovery,and stability,and the lack of appropriate designs for constructing ML devices represent significant challenges that remain to be addressed to boost the practical application of ML materials.Herein,ML hybrids derived from a natural source,waste eggshell,with the aforementioned attributes are demonstrated.The introduction of the eggshell not only enables the preparation of the hybrid in a simple and cost-effective manner but also contributes to the homochromatism(red,green,or blue emission),high brightness,and robustness of the resultant ML hybrids.The significant properties of the ML hybrids,together with the proposed structural design,such as porosity or core–shell structure,could expedite a series of mechanic-optical applications,including the self-luminous shoes for the conversion of human motions into light and light generators that efficiently harvest water wave energy.The fascinating properties,versatile designs,and the efficient protocol of“turning waste into treasure”of the ML hybrids represent significant advances in ML materials,promising a leap to the practical applications of this flouring material family. | Chunfeng Wang Ronghua Ma Dengfeng Peng Xianhu Liu Jing Li Boru Jin Aixian Shan Yu Fu Lin Dong Wenchao Gao Zhong Lin Wang Caofeng Pan | 2021 | InfoMat2021，3，11： | 1 |

| 8 | Interface synergistic effects induced multi-mode luminescence显示文摘Mechanoluminescence(ML)has become the most promising material for broad applications in display and sensing devices,in which ZnS is the most commonly studied one due to its stable and highly repetitive ML performances.In this work,we have successfully prepared the biphase ZnS on a large scale through the facile in-air molten salt protection strategy.The obtained biphase has the best ML properties,which is mainly attributed to the synergistic effects of piezo-photonic,defect,and interface dislocations.DFT calculations have confirmed that the defects activate the local S and Zn sites and reduce the energy barrier for electron transfer.The much stronger X-ray induced luminescence than the commercial scintillator is also reached.The application of ZnS particles in both papers and inks delivers superior performance.Meanwhile,ZnS particles based screen printing ink is able to directly print on paper,plastic and other carriers to form clear marks.These proposed paper and ink hold great potentials in applications of information security and anti-counterfeiting based on the multi-mode luminescence properties.This work provides a new avenue to understand and realize the high-performance multi-mode luminescence,inspiring more future works to extend on other ML materials and boosting their practical applications. | Ronghua Ma Chunfeng Wang Wei Yan Mingzi Sun Jianxiong Zhao Yuantian Zheng Xu Li Longbiao Huang Bing Chen Feng Wang Bolong Huang Dengfeng Peng | 2022 | Nano Research2022，15，5： | 1 |

| 12 | Photoluminescence and thermal stability of yellow-emitting Pr^(3+) doped CaAl_(2)O_(4) phosphors显示文摘Pr^(3+)-doped CaAl_(2)O_(4) phosphors with broad yellow emission were synthesized by conventional solid-state reaction in air and their structural and luminescent properties were investigated.A pure monoclinic structure can be obtained when the sintering temperature is 1400℃ or above.With photoluminescence(PL)measurement,the excitation was observed at 450–500 nm,which covered the emission of the blue light-emitting diode(LED)chips.Emission of the phosphors showed a green band and a red band.So these phosphors showed great potential in application of warm white LEDs without reabsorption.Additionally,the optimal emission intensity was obtained when Pr doping level was at 0.2 mol%.Furthermore,the Pr-doped CaAl_(2)O_(4) phosphors have the higher quenching temperature.With an increase in temperature,the emission bands of Pr-doped CaAl_(2)O_(4) showed an abnormal blue-shift. | Hua Zou Dengfeng Peng Zhenming Chu Xusheng Wang Yanxia Li Jun-Wei Hou Xi Yao | 2013 | Journal of Advanced Dielectrics2013，3，3： | 1 |

| 14 | Up-conversion luminescence of Er^(3+)and Yb^(3+)co-doped CaBi_(2)Ta_(2)O_(9) multifunctional ferroelectrics显示文摘Er^(3+)and Yb^(3+)co-doped CaBi_(2)Ta_(2)O_(9)(CBT)-based bismuth layered-structure oxides were synthesized by a simple solid-state reaction method.Their up-conversion(UC)luminescence,dielectric and ferroelectric properties were investigated.Two strong green emission bands centered at 526 and 547nm and a weak red emission band centered at 658nm were obtained under a 980nm laser excitation at room temperature.These emission bands originated from the radiative relaxation of Er^(3+)from 2H_(11)=2,4S_(3)=2,and 4F_(9/2) levels to the ground state 4I_(15)=2,respectively.At the meantime,the fluorescence intensity ratio(FIR)variation of two green UC emissions at 526 and 547nm has been studied as a function of temperature in the range of 153–603K.The maximum sensor sensitivity obtained was 39×10^(-4)K^(-1) at 590K,which indicated that Er^(3+)=Yb^(3+)co-doped CBT ceramic is a promising candidate for applications in optical high temperature sensor. | Qiufeng Cao Dengfeng Peng Hua Zou Jun Li Xusheng Wang Xi Yao | 2014 | Journal of Advanced Dielectrics2014，4，3： | 0 |
| 15 | Coffee Flower Identification Using Binarization Algorithm Based on Convolutional Neural Network for Digital Images显示文摘Crop-type identification is one of the most significant applications of agricultural remote sensing,and it is important for yield estimation prediction and field management.At present,crop identification using datasets from unmanned aerial vehicle(UAV)and satellite platforms have achieved state-of-the-art performances.However,accurate monitoring of small plants,such as the coffee flower,cannot be achieved using datasets from these platforms.With the development of time-lapse image acquisition technology based on ground-based remote sensing,a large number of small-scale plantation datasets with high spatial-temporal resolution are being generated,which can provide great opportunities for small target monitoring of a specific region.The main contribution of this paper is to combine the binarization algorithm based on OTSU and the convolutional neural network(CNN)model to improve coffee flower identification accuracy using the time-lapse images(i.e.,digital images).A certain number of positive and negative samples are selected from the original digital images for the network model training.Then,the pretrained network model is initialized using the VGGNet and trained using the constructed training datasets.Based on the well-trained CNN model,the coffee flower is initially extracted,and its boundary information can be further optimized by using the extracted coffee flower result of the binarization algorithm.Based on the digital images with different depression angles and illumination conditions,the performance of the proposed method is investigated by comparison of the performances of support vector machine(SVM)and CNN model.Hence,the experimental results show that the proposed method has the ability to improve coffee flower classification accuracy.The results of the image with a 52.5°angle of depression under soft lighting conditions are the highest,and the corresponding Dice(F1)and intersection over union(IoU)have reached 0.80 and 0.67,respectively. | Pengliang Wei Ting Jiang Huaiyue Peng Hongwei Jin Han Sun Dengfeng Chai Jingfeng Huang | 2020 | Plant Phenomics2020，2，1： | 0 |
| 16 | Thin,soft,skin-integrated electronics for real-time and wireless detectionof uricacid in sweat显示文摘Wearable sweat sensors are gaining significant attention due to their unparalleled potential for noninvasive health monitoring.Sweat,as a kind of body fluid,contains informative physiological indicators that are related to personalized health status.Advances in wearable sweat sampling and routing technologies,flexible,and stretchable materials,and wireless digital technologies have led to the development of integrated sweat sensors that are comfortable,flexible,light,and intelligent.Herein,we report a flexible and integrated wearable device via incorporating a microfluidic system and a sensing chip with skin-integrated electronic format toward in-situ monitoring of uric acid(UA)in sweat that associates with gout,cardiovascular,and renal diseases.The microfluidic system validly realizes the real-time capture perspiration from human skin.The obtained detection range is 5-200μM and the detection limit is 1.79μM,which offers an importance diagnostic method for clinical relevant lab test.The soft and flexible features of the constructed device allows it to be mounted onto nearly anywhere on the body.We tested the sweat UA in diverse subjects and various body locations during exercise,and similar trends were also observed by using a commercial UA assay kit. | Yue Hu Lan Wang Jian Lia Yawen Yang Guangyao Zhao Yiming Liu Xingcan Huang Pengcheng Wu Binbin Zhang Yanli Jia Mengge Wu Shengxin Jia Qiang Zhang Guoqiang Xu Rui Shi Dengfeng Li Yingchun Li Zhengchun Peng Xinge Yu | 2023 | International Journal of Smart and Nano Materials2023，14，4： | 0 |
| 17 | Physical and emulsifying properties of pea protein:influence of combined physical modification by flaxseed gum and ultrasonic treatment显示文摘This study characterized and compared the physical and emulsifying properties of pea protein(PP)and its modified proteins(ultrasound treated-PP(PPU),flaxseed gum(FG)treated PP(PPFG)and ultrasound treated-PPFG(PPFGU)).The results showed FG triggered the formation of loosely attached complex with PP via physical modification under gentle magnetic stirring at pH 7.0,while ultrasound played an important role in reducing protein size,increasing surface hydrophobicity and molecular fluidity onto oil-water interface.So ultrasound further enhanced the interaction of PP with FG,and produced the PPFGU complex with smaller droplet size,higherζ-potential and lower turbidity.Further,combination of FG and ultrasound improved the physical properties of PP with higher viscosity,stiffer gels(defined as higher elastic modulus),stronger hydrophobic properties,better thermal stability,and fast protein absorption rate.Therefore,the PPFGU coarse emulsion performed highest emulsifying activity index(EAI)and emulsion stability index(ESI)that the stabilized nanoemulsion obtained smallest droplet size,higherζ-potential,and longest storage stability.The combination of FG and ultrasonic treatment will be an effective approach to improving the emulsifying property and thermal stability of PP,which can be considered as a potential plant-based emulsifier applied in the food industry. | Jia Yang Fenghong Huang Qingde Huang Da Ma Yashu Chen Dengfeng Peng Xiao Yu Qianchun Deng Fang Geng | 2023 | Food Science and Human Wellness2023，12，2： | 0 |
| 18 | Band modification towards high thermoelectric performance of SnSb_(2)Te_(4) with strong anharmonicity driven by cation disorder显示文摘As a typical (IV–VI)_(x)(V_(2)VI_(3))_(y) compound, the tetradymite-like layered SnSb_(2)Te_(4) -based compounds have attracted increasing attention in the thermoelectric community owing to the intrinsically low lattice thermal conductivity. Nevertheless, the effect of cations disorder on the inherent physical characteristics remains puzzling, and its inferior Seebeck coefficient is the bottleneck to achieving high thermoelectric performance. In this work, the thermoelectric properties of polycrystalline In_(x)Sn_(1−x)Sb_(2)(Te_(1−y)Se_(y))_(4) (0≤x≤0.1,0≤y≤0.15) samples are comprehensively investigated. In conjunction with the calculated band structure and experimental results, the Seebeck coefficient and power factor are markedly improved after the introduction of indium and selenium, which originates from the combined effects of the emergent resonant states and converged valence bands along with optimal carrier concentration. Additionally, compared with the ordered lattice structure, the disordered cations occupancy in SnSb_(2)Te_(4) further strengthens lattice anharmonicity and reduces phonon group velocity verified by first-principles calculations, securing intrinsically low lattice thermal conductivity. Finally, a record zT value of ∼0.6 at 670 K and an average zT of ∼0.4 between 320 and 720 K are obtained in the In0.1 Sn0.9 Sb2 Te3.4 Se0.6 sample, being one of the highest zT values among SnSb2 Te4 -based materials. This work not only demonstrates that SnSb2 Te4 -based compounds are promising thermoelectric candidates, but also provides guidance for the promotion of thermoelectric performance in a broad temperature range. | Hong Wu Peng Chen Zizhen Zhou De Zhang Xiangnan Gong Bin Zhang Yang Zhou Kunling Peng Yanci Yan Guiwen Wang Jun Liu Dengfeng Li Guang Han Guoyu Wang Xu Lu Xiaoyuan Zhou | 2023 | Journal of Materials Science & Technology2023，，23： | 0 |
| 19 | Functional genomics of Brassica napus:Progresses,challenges,and perspectives显示文摘Brassica napus,commonly known as rapeseed or canola,is a major oil crop contributing over 13%to the stable supply of edible vegetable oil worldwide.Identification and understanding the gene functions in the B.napus genome is crucial for genomic breeding.A group of genes controlling agronomic traits have been successfully cloned through functional genomics studies in B.napus.In this review,we present an overview of the progress made in the functional genomics of B.napus,including the availability of germplasm resources,omics databases and cloned functional genes.Based on the current progress,we also highlight the main challenges and perspectives in this field.The advances in the functional genomics of B.napus contribute to a better understanding of the genetic basis underlying the complex agronomic traits in B.napus and will expedite the breeding of high quality,high resistance and high yield in B.napus varieties. | Zengdong Tan Xu Han Cheng Dai Shaoping Lu Hanzi He Xuan Yao Peng Chen Chao Yang Lun Zhao Qing-Yong Yang Jun Zou Jing Wen Dengfeng Hong Chao Liu Xianhong Ge Chuchuan Fan Bing Yi Chunyu Zhang Chaozhi Ma Kede Liu Jinxiong Shen Jinxing Tu Guangsheng Yang Tingdong Fu Liang Guo Hu Zhao | 2024 | Journal of Integrative Plant Biology2024，66，3： | 0 |
| 20 | Halogen-doped phosphorescent carbon dots for grayscale patterning显示文摘Flexible organic materials that exhibit dynamic ultralong room temperature phosphorescence(DURTP)via photoactivation have attracted increasing research interest for their fascinating functions of reversibly writing-reading-erasing graphic information in the form of a long afterglow.However,due to the existence of a nonnegligible activation threshold for the initial exposure dose,the display mode of these materials has thus far been limited to binary patterns.By resorting to halogen element doping of carbon dots(CDs)to enhance intersystem crossing and reduce the activation threshold,we were able to produce,for the first time,a transparent,flexible,and fully programmable DURTP composite film with a reliable grayscale display capacity.Examples of promising applications in UV photography and highly confidential steganography were constructed,partially demonstrating the broad future applications of this material as a programmable platform with a high optical information density. | Yanfeng Liu Mahmoud Al-salihi Yong Guo Roman Ziniuk Songtao Cai Luwei Wang Yuan Li Zhigang Yang Dengfeng Peng Kai Xi Zhongfu An Xudong Jia Liwei Liu Wei Yan Junle Qu | 2022 | Light(Science & Applications)2022，11，7： | 0 |
