| 2 | Influence of processing parameters on the phase composition of ZrN-Si_3N_4 synthesized from zircon显示文摘The optimum parameters were determined for synthesizing ZrN-Si3N4 composite powder from zircon by carbothermal reduction-nitridation (CTRN) process. The samples were prepared by mixing the carbon black of an average particle size less than 30 μm and the zircon of 40 μm with C/ZrSiO4 mass ratios of 0.2, 0.3, 0.4, and 0.5. The prepared samples were subjected to the CTRN process at temperatures of 1673, 1723, 1753, and 1773 K for 6, 9, and 12 h. The CTRN process was conducted in an atmosphere-controlled tubular furnace in a nitrogen gas flow of 1.0 L/min. All the products were examined by X-ray powder diffraction to determine the transformation. The results showed that the proper transformation of ZrN-Si3N4 occurred at 1773 K for 12 h with a C/ZrSiO4 mass ratio of 0.4. | MA Beiyue YU Jingkun | 2009 | Rare Metals2009，28，4： | 10 |
| 3 | Synthesis of Al_2O_3-SiC Composite and Its Effect on the Properties of Low-carbon MgO-C Refractories显示文摘Al2O3-SiC composite was synthesized with pyrophyllite and natural graphite as raw materials by carbothermal reduction reaction under argon atmosphere. The effect of synthesis temperature on phase composition and microstructure was investigated. Low-carbon MgO-C refractories were prepared by using the synthesized Al2O3-SiC composite as additive. The effect of its addition on the slag penetration and corrosion resistance as well as oxidation resistance of the refractories was investigated, and the slag resistance and oxidation resistance mechanisms of the Al2O3-SiC composite were also discussed. The results show that the synthesis temperature has a great influence on preparation of Al2O3-SiC composite. The Al2O3-SiC composite can be synthesized at 1873-1973 K under argon atmosphere, with pyrophyllite and natural graphite as raw materials, and particle sizes of the composite synthesized at 1973 K are mainly distributed as 1-2 μm. The slag penetration and corrosion resistance of low-carbon MgO-C refractories can be remarkably improved by adding the synthesized Al2O3-SiC composite, and the oxidation resistance has an improvement to some extent. The increase of slag viscosity and the formation of MgAl2O4 can effectively inhibit the slag penetration and corrosion for the refractories. | Beiyue Ma Qiang Zhu Yong Sun Jingkun Yu Ying Li | 2010 | Journal of Materials Science & Technology2010，26，8： | 9 |

Test samples were prepared by mixing average mesh size of less than 30 μm of carbon black and 40 μm of zircon with C/ZrSiO4 mass ratio of 0.2 and the extra addition amount of La2O3 was 0, 1 wt.% and 2 wt.%. Prepared samples were subjected to the car-bothermal reduction process at temperatures of 1723, 1753, 1773 and 1803 K for 4 h, respectively. The carbothermal reduction process was conducted in an atmosphere controlled tube furnace at an argon flow of 1.5 L/min. All products were examined by X-ray diffraction (XRD) to determine the transformation. The results showed that the best transformation of SiC-ZrO2 composite materials occurred at 1803 K for 4 h with the amount of 2 wt.%La2O3. | MA Beiyue YU Jingkun | 2009 | Journal of Rare Earths2009，27，5： | 6 |
| 5 | Preparation of SiC Porous Ceramics by Crystalline Silicon Cutting Waste显示文摘SiC porous ceramics were prepared at 1 400 ℃ for4 h with crystalline silicon cutting waste and activated carbon as main starting materials and NH_4HCO_3 as the pore-forming agent. Effects of NH_4HCO_3 additions( 0,20%,30%,40%,by mass) on the phase composition,microstructure,sintering properties,cold compressive strength and thermal shock resistance of as-prepared Si C porous ceramics were investigated. The results show that:( 1) addition of NH_4HCO_3 remarkably influences the apparent porosity and cold compressive strength of specimens. The apparent porosity achieves its maximum value( 63. 40%) when 40% NH_4HCO_3 is added,while the minimum cold compressive strength is 4. 77 MPa;( 2) the specimen with 40% NH_4HCO_3 has the best thermal shock resistance. The thermal cycling times between1 000 ℃ to room temperature reach 62;( 3) the addition of NH_4HCO_3 does not remarkably affect the phase composition of the specimens;( 4) the specimens include a large number of SiC particles and a small amount of SiC whiskers. | ZHANG Yaran MA Beiyue YU Jingyu SU Chang REN Xinming QIAN Fan LIU Guoqi LI Hongxia YU Jingkun | 2018 | China's Refractories2018，27，4： | 3 |
| 6 | Epidermal self-powered sweat sensors for glucose and lactate monitoring显示文摘Sweat could be a carrier of informative biomarkers for health status identification;therefore,wearable sweat sensors have attracted significant attention for research.An external power source is an important component of wearable sensors,however,the current power supplies,i.e.,batteries,limit further shrinking down the size of these devices and thus limit their application areas and scenarios.Herein,we report a stretchable self-powered biosensor with epidermal electronic format that enables the in situ detec-tion of lactate and glucose concentration in sweat.Enzymatic biofuel cells serve as self-powered sensing modules allowing the sweat sensor to exhibit a determination coefficient(R2)of 0.98 with a sensitivity of 2.48 mV/mM for lactate detection,and R2 of 0.96 with a sensitivity of 0.11 mV/μM for glucose detection.The microfluidic channels developed in an ultra-thin soft flexible polydimethylsiloxane layer not only enable the effective collection of sweat,but also provide excellent mechanical properties with stable performance output even under 30%stretching.The presented soft sweat sensors can be integrated at nearly any location of the body for the continuous monitoring of lactate and glucose changes during normal daily activities such as exercise.Our results provide a promising approach to develop next-generation sweat sensors for real-time and in situ sweat analysis. | Xingcan Huang Jiyu Li Yiming Liu Tszhung Wong Jingyou Su Kuanming Yao Jingkun Zhou Ya Huang Hu Li Dengfeng Li Mengge Wu Enming Song Shijiao Han Xinge Yu | 2022 | Bio-Design and Manufacturing2022，5，1： | 3 |
| 7 | Electron-phonon coupling-assisted universal red luminescence of o-phenylenediamine-based carbon dots显示文摘Due to the complex core-shell structure and variety of surface functional groups,the photoluminescence(PL)mechanism of carbon dots(CDs)remain unclear.o-Phenylenediamine(oPD),as one of the most common precursors for preparing red emissive CDs,has been extensively studied.Interestingly,most of the red emission CDs based on oPD have similar PL emission characteristics.Herein,we prepared six different oPD-based CDs and found that they had almost the same PL emission and absorption spectra after purifiication.Structural and spectral characterization indicated that they had similar carbon core structures but diffferent surface polymer shells.Furthermore,single-molecule PL spectroscopy confirmed that the multi-modal emission of those CDs originated from the transitions of different vibrational energy levels of the same PL center in the carbon core.In addition,the phenomenon of'spectral splitting'of single-particle CDs was observed at low temperature,which confirmed these oPD-based CDs were unique materials with properties of both organic molecules and quantum dots.Finally,theoretical calculations revealed their potential polymerization mode and carbon core structure.Moreover,we proposed the PL mechanism of red-emitting CDs based on oPD precursors;that is,the carbon core regulates the PL emission,and the polymer shell regulates the PL intensity.Our work resolves the controversy on the PL mechanism of oPD-based red CDs.These findings provide a general guide for the mechanism exploration and structural analysis of other types of CDs. | Boyang Wang Zhihong Wei Laizhi Sui Jingkun Yu Baowei Zhang Xiaoyong Wang Shengnan Feng Haoqiang Song Xue Yong Yuxi Tian Bai Yang Siyu Lu | 2022 | Light(Science & Applications)2022，11，7： | 2 |
| 8 | Influences of ZrO_2-SiC Composite Powder and Commercial SiC on Properties of Al_2O_3-C Refractories显示文摘In order to improve oxidation resistance and thermal shock resistance of Al2O3-C refractories, two groups of specimens were prepared with phenolic resin as binder, adding 0, 2 wt%, 4 wt% and 6 wt% commercial SiC or ZrO2-SiC composite powder synthesized from zircon respectively to Al2O3-C refractories, pressing at 200 MPa, drying fully at 250 ℃, and then carbon embedded firing at 1 400 ℃ for 2 h. Oxidation resistance and thermal shock resistance were researched, phase composition was analyzed by XRD. The results showed that the oxidation of SiC in additives could protect carbon in specimens effectively and thus decreased the mass loss ratio and oxidation area, and improved the oxidation resistance of the specimen. Thermal shock resistance was improved owing to the micro crack toughening of ZrO2 and grain toughening of SiC. In this experiment, the specimens with 6 wt% ZrO2-SiC composite powder or 6 wt% SiC powder had the best oxidation resistance and thermal shock resistance. | MA Beiyue YU Jingkun SUN Yong ZHU Qiang | 2008 | China's Refractories2008，17，3： | 2 |
| 9 | Carbohydrate-derived porous carbon materials:An ideal platform for green organic synthesis显示文摘Porous carbon materials have attracted much attention in the field of organic synthesis in recent years,due to their tunable properties,excellent catalytic activity and stability.Biomass-based carbohydrates emerge as an ideal precursor for the generation of these materials owing to their renewability,low cost,non-toxicity and high content of functional groups.Thus,carbon materials prepared from carbohydrates is of considerable importance for the sustainable development of organic chemistry.The present review not only summarizes recent examples of carbohydrate-derived porous carbon material-catalyzed organic reactions including the oxidation,hydrogenation,cross-coupling,esterification and condensation reactions,but also introduces the preparation and functionalization strategies of these materials.Furthermore,the challenges and opportunities of organic synthesis over these sustainable materials have also been addressed.This review will stimulate further research on exploring novel carbohydrate-derived porous carbon materials and new sustainable organic synthetic processes over these materials. | Yamei Lin Jie Yu Xing Zhang Jingkun Fang Guo-Ping Lu He Huang | 2022 | Chinese Chemical Letters2022，33，1： | 2 |

| 11 | Preparation of ZrN(ZrON)-SiAION Composite Ceramics via a Pressureless Sintering Process显示文摘ZrN- SiA lO N composite materials were synthesized at 1 550 ℃ for 6 h via a carbothermal reduction nitridation route using fly ash( ≤74 μm),zircon( ≤44 μm)and active carbon as starting materials. The processed ZrN- SiA lO N composite micropowders were mixed with polyvinyl alcohol as binder to prepare ZrN( ZrO N)-SiA lO N composite ceramics by carbon-embedded pressureless firing at 1 450,1 500 and 1 550 ℃ for 1 h,respectively. Influences of firing temperature on the phase compositions,microstructure and sintering properties of the ceramics were investigated. The results show that:( 1)β-SiA lO N based composite ceramics with different compositions can be prepared by controlling firing temperature,and the main crystalline phases of the specimen fired at1 550 ℃ for 1 h involve ZrN,ZrO N and β-SiA lO N( z =2,Si4Al2O2N6);( 2) ZrN( ZrO N),β-SiA lO N and a Fe- Si based compound can be observed in the microstructures of the specimens fired at different temperatures.ZrN( ZrO N) particles distribute homogeneously in theβ-SiA lO N matrix;( 3) raising firing temperature can increase the shrinkage ratio of the ceramics,and the volume shrinkage ratio increases from 19. 4% to 40. 3% when the firing temperature rises from 1 450 to 1 550 ℃. | MA Beiyue LI Ying LU Zhongxin YU Jingkun | 2014 | China's Refractories2014，23，4： | 2 |

| 15 | Single stain hyperspectral imaging for accurate fungal pathogens identification and quantification显示文摘The most widely used method of identification of microbial morphology and structure is microscopy,but it can be difficult to distinguish between pathogens with a similar appearance.Existing fluorescent staining methods require a combination of a variety of fluorescent materials to meet this demand.In this study,unique concentration-dependent fluorescent carbon dots(CDs)were synthesized for the identification and quantification of pathogens.The emission wavelength of the CDs could be tuned spanning the full visible region by virtue of aggregation-induced narrowing of bandgaps.This tunable emission wavelength of the specific concentration response to diverse microbes can be used to distinguish microorganisms with a similar appearance,even in a same genus.A hyperspectral microscopy system was demonstrated to distinguish Aspergillus flavus and A.fumigatus based on the results above.The identification accuracy of the two similar-looking pathogens can be close to 100%,and the relative proportions and spatial distributions can also be profiled from the mixture of the pathogens.This technique can provide a solution to the fast detection of microorganisms and is potentially applicable to a wide range of problems in areas such as healthcare,food preparation,biotechnology,and health emergency. | Yongqiang Zhang Kunxing Liu Jingkun Yu Haifeng Chen Rui Fu Siqi Zhu Zhenqiang Chen Shuangpeng Wang Siyu Lu | 2022 | Nano Research2022，15，7： | 1 |
