| 1 | A novel microwave absorber——BaAl_2Fe_(10)O_(19)/poly(m-toluidine) composite:Preparation and electromagnetic properties显示文摘BaFe10Al2O19 /poly(m-toluidine)(BFA/PMT) composites were synthesized by in-situ polymerization of m-toluidine in the presence of BaFe10Al2O19 particles.The structure,composition and morphology of the obtained samples were characterized by using XRD,FT-IR,UV-visible spectroscopy,SEM and TEM techniques.Their electrical conductivity,magnetic property and microwave absorbing property were measured by the four-probe meter,the vibrating sample magnetometer and the vector network analyzer,respectively.The results indicated that BFA particles were coated effectively by PMT polymer and some interactions between PMT and BFA particles existing in the composites.The conductivity of BFA/PMT composite is smaller than that of pure polymers and its saturation magnetization is a little smaller than that of pure BFA.The influence of the constitution and film thickness of absorbent on its microwave absorbing property is evident.The microwave absorbing properties of the BFA/PMT composites are better than those of pure BFA and PMT.When optimizing the mass rate of BFA/PMT to 0.3,the absorbent with 2 mm film thickness has the minimum reflection loss of 28.26 dB at approximate 14.24 GHz,and the maximum available bandwidth of 8.8 GHz,respectively.The results show that these composites can be used as advancing absorption and shielding materials due to their favorable microwave absorbing property. | CHEN KeYu XU QingQing LI LiangChao GONG PeiJun CHEN HaiFeng XIAO QiuShi Xu Feng | 2012 | Science China Chemistry2012，55，7： | 4 |
| 2 | Controlled fabrication and electrical-magnetic properties of Poly(OT-co-AN)/Ba_(0.8)La_(0.2)Al_2Fe_(10)O_(19) composites显示文摘Poly(OT-co-AN)/Ba0.8La0.2Al2Fe10O19(Poly(OT-co-AN)/BLAF) composites were fabricated by in situ polymerization method.It was investigated that of mass rate of momomer(mOT/mAN),polymeration temperature and time,and feeding ratio of BLAF effect on the structures,morphology,conductivity,magnetic property of composites by the orthogonal optimum design.The results indicated that poly(OT-co-AN) copolymer had a better coating on BLAF particles,and there were some interactions between components in the composites.The magnetic properties of the composites were related to content of the magnetic BLAF particles in it.The feeding ratio of BLAF had a significant influence on constitute and conductivity of the composites,followed by the temperature.The reflection loss and the effective bandwidth of composites for electromagnetic wave were at-tributed to the synergistic effect between poly(OT-co-AN) and BLAF.The poly(OT-co-AN)/BLAF composites with mass ratio of BLAF to mix monomer(mOT/mAN =1:1) equal to 5/1 at 10 h in 25°C had a maximum synergistic effect between its compo-nents,showed a maximum reflection loss of ?26.94 dB at 14.10 GHz and an available bandwidth of 8.54 GHz.It was sug-gested that the composites can be used as a advancing absorption and shielding materials for electromagnetic wave due to their favorable microwave absorption properties. | CHEN KeYu XU QingQing LI LiangChao TONG GuoXiu QIAN HaiSheng XIAO QiuShi XU Feng | 2012 | Science China(Technological Sciences)2012，55，1： | 4 |

| 6 | Flexible,stretchable,and transparent InGaN/GaN multiple quantum wells/polyacrylamide hydrogel-based light emitting diodes显示文摘Visualization is a direct,efficient,and simple interface method to realize the interaction between human and machine,whereas the flexible display unit,as the major bottleneck,still deeply hinders the advances of wearable and virtual reality devices.To obtain flexible optoelectronic devices,one of the effective methods is to transfer a high-efficient and long-lifetime inorganic optoelectronic film from its rigid epitaxial substrate to a foreign flexible/soft substrate.Additionally,piezo-phototronic effect is a fundamental theory for guiding the design of flexible optoelectronic devices.Herein,we demonstrate a flexible,stretchable,and transparent InGaN/GaN multiple quantum wells(MQWs)/polyacrylamide(PAAM)hydrogel-based light emitting diode coupling with the piezo-phototronic effect.The quantum well energy band and integrated luminous intensity(increased by more than 31.3%)are significantly modulated by external mechanical stimuli in the device.Benefiting from the small Young's modulus of hydrogel and weak Van der Waals force,the composite film can endure an extreme tensile condition of about 21.1%stretching with negligible tensile strains transmitted to the InGaN/GaN MQWs.And the stable photoluminescence characteristics can be observed.Moreover,the hydrogen-bond adsorption and excellent transparency of the hydrogel substrate greatly facilitate the packaging and luminescence of the optoelectronic device.And thus,such a novel integration scheme of inorganic semiconductor materials and organic hydrogel materials would help to guide the robust stretchable optoelectronic devices,and show great potential in emerging wearable devices and virtual reality applications. | Jiwei Chen Jiangwen Wang Keyu Ji Bing Jiang Xiao Cui Wei Sha Bingjun Wang Xinhuan Dai Qilin Hua Lingyu Wan Weiguo Hu | 2022 | Nano Research2022，15，6： | 1 |

| 11 | Studies on Growth-promoting Function and Mechanism of Extract from Grape Seed and Sweet Wormwood on Monopterus albus显示文摘[Objectives]The effect and mechanism of grape seed and sweet wormwood extract on growth of Monopterus albus were studied.[Methods]1 500 healthy M.albus with average mass of 23.8 g/tail were randomly divided into 5 groups.The control group was fed with basal diet and the experimental groups were fed with 10,20,30 and 40 g/kg of grape seed and sweet wormwood extract,respectively.The growth performance of the fish was measured after 60 d of feeding at 23-28℃.[Results]The addition of grape seed and sweet wormwood extract in basal diet could increase the body weight gain rate,specific growth rate and protein efficiency,and decrease the feed coefficient.The activity of digestive enzymes,glutamic-oxaloacetic transaminase,glutamic-pyruvic transaminase,blood alkaline phosphatase and serum total protein was increased,and the contents of blood glucose and triglyceride were decreased.Compared with the control group,the above indexes showed significant difference(P<0.05)when the dosage was 20 and 30 g/kg(P<0.05).The difference was not significant(P>0.05)when the dosage was 10 and 40 g/kg(P>0.05).[Conclusions]As a feed additive,the plant extract from grape seed and sweet wormwood could increase digestive enzyme activity and regulate blood biochemical parameters of fish body.It had the function of promoting the digestion and absorption,enhancing the metabolic activity of 3 main nutrients,and hastening the growth of fish. | Guangzhong HUANG Zhongbo LI Shimin LUO Xu YANG Keyu XIAO Hui HU Peirong XIE | 2019 | Agricultural Biotechnology2019，8，4： | 0 |
| 12 | Cross‑sectional Exploration of the Relationship Between Glutamate Abnormalities and Tic Disorder Severity Using Proton Magnetic Resonance Spectroscopy显示文摘Glutamate(Glu)has been reported to be closely related to the pathophysiology of Tic Disorders(TD).By using proton mag-netic resonance spectroscopy(1H-MRS),we aimed to investigate the relationship between in vivo Glu levels and the severity of TD.We performed a cross-sectional study in medication-free patients with TD and healthy controls aged between 5 and 13 years using 1H-MRS at 3 T.First,we measured the Glu levels in both patients and controls and observed the difference in subgroups,including mild TD patients and moderate TD patients.We then examined the correlations between the Glu levels and clinical features of the patients.Finally,we assessed the diagnostic value of 1H-MRS and the influencing factors.Our results show that the Glu levels in the striatum of all patients with TD were not significantly different from those of the healthy controls.Subgroup analysis revealed that the Glu levels in the moderate TD group were higher than those in the mild TD group and healthy controls.The correlation analysis showed that Glu levels are strongly positive correlated with TD severity.The optimal cutoff value of Glu levels to differentiate mild tics from moderate tics was 1.244,with a sensitivity of 88.2%and a specificity of 94.7%.Multiple linear regression models revealed that the severity of TD is one of the important factors that affect Glu levels.We conclude that Glu levels are mainly associated with the severity of tics,thus it could serve as a key biomarker for TD classification. | Juanjuan Hao Xin Zhang Ying Liu Zhongyang Zhang Keyu Jiang Xiao‑Yong Zhang Min Wu | 2023 | Phenomics2023，3，2： | 0 |
| 13 | Broad-intensity-range optical nonreciprocity based on feedback-induced Kerr nonlinearity显示文摘Nonreciprocal light propagation plays an important role in modern optical systems,from photonic networks to integrated photonics. We propose a nonreciprocal system based on a resonance-frequency-tunable cavity and intensity-adaptive feedback control. Because the feedback-induced Kerr nonlinearity in the cavity is dependent on the incident direction of light,the system exhibits nonreciprocal transmission with a transmission contrast of 0.99 and an insertion loss of 1.5 dB. By utilizing intensity-adaptive feedback control,the operating intensity range of the nonreciprocal system is broadened to 20 dB,which relaxes the limitation of the operating intensity range for nonlinear nonreciprocal systems. Our protocol paves the way to realize high-performance nonreciprocal propagation in optical systems and can also be extended to microwave systems. | LEI TANG JIANGSHAN TANG HAODONG WU JING ZHANG MIN XIAO KEYU XIA | 2021 | Photonics Research2021，9，7： | 0 |
