| 1 | Porous SiC Prepared Using Fine α-Al2O3 and SiC Powders as Sintering Additives显示文摘A reaction bonding technique and a method of layer coating were developed to fabricate porous SiC.The green body was prepared using 250.0μm SiC particles as the raw material,fineα-Al2O3 and SiC powders with mass ratio of 2.5:1as sintering additives,65.2μm graphite as the pore-forming agent and polyvinyl alcohol(PVA)as the binder.The micro powders were coated on the surface of coarse SiC particles.After sintering,fine SiC particles were oxidized to silica(SiO2)then transforming into cristobalite,which finally reacted withα-Al2O3 to produce mullite(3Al2O3·2SiO2).The results show that SiC particles are bonded by the mullite and oxidation-derived SiO2.The apparent porosity of the specimens decreases from 31.3%to 20.5%with the amount of micro powders increasing from 5 mass%to 20 mass%.The bending strength increases at the first stage and then decreases with the increase of fine powders,and the specimen with 10 mass%of fine powders shows relatively high bending strength of 23.5 MPa. | LIU Jiadong PENG Zhijian LIU Qingzhu SUN Guangchao LIU Kaiqi | 2019 | China's Refractories2019，28，2： | 2 |
| 2 | Photocrosslinking silver nanoparticles–aloe vera–silk fibroin composite hydrogel for treatment of full-thickness cutaneous wounds显示文摘Damage to the skin causes physiological and functional issues.The most effective treatment approach is the use of wound dressings.Silk fibroin(SF)is a promising candidate biomaterial for regulating wound healing;however,its antibacterial properties and biological activity must be further improved.In this study,a photocrosslinking hydrogel was developed to treat full-thickness cutaneous wounds.The composite hydrogel(Ag-AV-SF hydrogel)was prepared by introducing the silver nanoparticles(AgNPs)and aloe vera(AV)as the modifiers.In vitro study exhibited great antibacterial ability,biocompatibility and cell-proliferation and-migration-promoting capacities.It also showed the pH-response releasing properties which release more AgNPs in a simulated chronic infection environment.The healing effect evaluation in vivo showed the healing-promoting ability of the Ag-AV-SF hydrogel was stronger than the single-modifiers groups,and the healing rate of it reached 97.02%on Day 21,higher than the commercial wound dressing,silver sulfadiazine(SS)cream on sale.Additionally,the histological and protein expression results showed that the Ag-AV-SF hydrogel has a greater effect on the pro-healing regenerative phenotype with M2 macrophages at the early stage,reconstructing the blood vessels networks and inhibiting the formation of scars.In summary,the Ag-AV-SF hydrogel developed in this study had good physical properties,overwhelming antibacterial properties,satisfactory biocompatibility and significantly promoting effect on cell proliferation,migration and wound healing.Overall,our results suggest that the Ag-AV-SF hydrogel we developed has great potential for improving the wound healing in clinical treatment. | Yangkun Liu JinChuan Fan MingQi Lv Kepeng She Jiale Sun Qingqing Lu Changhao Han SongTao Ding Shuang Zhao GuiXue Wang YuChan Zhang GuangChao Zang | 2021 | Regenerative Biomaterials2021，8，6： | 2 |
| 3 | Heteroatom substitution-induced asymmetric A–D–A type non-fullerene acceptor for efficient organic solar cells显示文摘Research on asymmetric A–D–A structured non-fullerene acceptors has lagged far behind the development of symmetric counterpart.In this contribution,by simply replacing one sulfur atom in indacenodithiophene unit with a selenium atom,an asymmetric building block Se PT and a corresponding asymmetric non-fullerene acceptor Se PT-IN have been developed.Asymmetric Se PT-IN achieved a high efficiency of 10.20% in organic solar cells when blended with PBT1-C,much higher than that of symmetric TPT-IN counterpart(8.91%).Our results demonstrated an effective heteroatom substitution strategy to develop asymmetric A–D–A structured non-fullerene acceptors. | Chao Lia Jiali Song Yunhao Cai Guangchao Han Wenyu Zheng Yuanping Yi Hwa Sook Ryu Han Young Woo Yanming Sun | 2020 | Journal of Energy Chemistry2020，29，1： | 2 |

| 7 | Thoughts on Pairing Assistance to Tibet for Promoting Agricultural High-quality Development in Southern Tibet from the Perspective of Agricultural Power显示文摘In the new era,there is an urgent need to further promote pairing assistance to Tibet,promote the simultaneous construction of a strong agriculture in Tibet and the China's Mainland,and compose a Chinese-style modernization.Southern Tibet,located in the southeastern part of the Tibet Autonomous Region,includes Shannan City and Nyingchi City,is a region assisted by four provincial partners including Hubei Province.This paper introduces the agricultural environment in southern Tibet,studies its agricultural characteristics,and analyzes the main issues of its pairing assistance.Taking forging the strong consciousness of the Chinese national community as the main line,the paper explores strategies for promoting agricultural high-quality development in southern Tibet through pairing assistance to Tibet from the perspective of agricultural power,and proposes some strategies,such as inheriting agricultural cultural heritage,promoting the upgrading of modern seed industry,enhancing the characteristic advantages of highland barley(naked barley)and animal husbandry industries,and developing edible fungi and cold water fish industries. | Zhiguo SUN Li GAO Yuanpeng SUN Guangchao CAO Xinying ZHOU Xiaoqiang LI | 2024 | Asian Agricultural Research2024，16，3： | 0 |
| 8 | Inhibition of MALT1 paracaspase activity improves lesion recovery following spinal cord injury显示文摘Spinal cord injury(SCI) is a devastating traumatic injury that causes persistent, severe motor and sensory dysfunction. Immune responses are involved in functional recovery after SCI. Mucosa-associated lymphoid tissue lymphoma translocation 1(MALT1) has been shown to regulate the survival and differentiation of immune cells and to play a critical role in many diseases, but its function in lesion recovery after SCI remains unclear. In this paper, we generated KI(knock in) mice with a point mutation(C472 G) in the active center of MALT1 and found that the KI mice exhibited improved functional recovery after SCI.Fewer macrophages were recruited to the injury site in KI mice and these macrophages differentiated into anti-inflammatory macrophages. Moreover, macrophages from KI mice exhibited reduced phosphorylation of p65, which in turn resulted in decreased SOCS3 expression and increased pSTAT6 levels.Similar results were obtained upon inhibition of MALT1 paracaspase with the small molecule inhibitor‘‘MI-2' or the more specific inhibitor ‘‘MLT-827'. In patients with SCI, peripheral blood mononuclear cells(PBMC) displayed increased MALT1 paracaspase. Human macrophages showed reduced proinflammatory and increased anti-inflammatory characteristics following the inhibition of MALT1 paracaspase. These findings suggest that inhibition of MALT1 paracaspase activity in the clinic may improve lesion recovery in subjects with SCI. | Hua Zhang Guodong Sun Xiaowei Li Zhen Fu Chengbin Guo Guangchao Cao Baocheng Wang Qian Wang Shuxian Yang Dehai Li Xichun Xia Peng Li Jing Zhu Wei Zhou Liangyan Zheng Jingxia Li Lei Zhang Jianlei Hao Libing Zhou Frederic Bornancin Zhizhong Li Zhinan Yin Yunfei Gao | 2019 | Science Bulletin2019，64，16： | 0 |
| 9 | Phase Reconstruction and Microstructure Evolution of Magnesia-carbon Refractories at High Temperatures in Nitrogen显示文摘Magnesia-carbon refractories were prepared using fused magnesia,flake graphite and metal aluminum powder as starting materials,phenolic resin as the binder,heat-treating at 1300-1600℃in nitrogen atmosphere.The phase reconstruction and the microstructure evolution of the obtained magnesia-carbon refractories were analyzed.The formation mechanisms of magnesia crystals with different morphologies by chemical vapor deposition were revealed.The results show that at 1300-1500℃,the non-oxides within the specimens are aluminum carbide(Al_(4)C_(3)),aluminum nitride(AlN)and magnesium aluminum nitride(Mg_(3)Al_(n)N_(n+2),n=2 or 3);at 1600℃,the diffraction characteristic peak intensity of Al_(4)C_(3) and AlN decreases sharply,and sharp diffraction characteristic peaks of nitrogen aluminum carbide(Al_(7)C_(3)N_(3))appear.Mg(g)is produced by the aluminothermic reduction and carbothermal reduction of magnesia.On the surface of the specimens,Mg(g)reacts with oxygen to form MgO whiskers.Inside the specimens,Mg(g)and O_(2)(g)undergo a CVD chemical deposition reaction to form cubic MgO crystals.There is a phase relationship between flake AlN and flake Mg3AlnNn+2,and they are so associated with each other that the morphology is difficult to distinguish. | YAN Mingwei YANG Yumin TONG Shanghao ZHANG Jiayu SUN Guangchao LIU Kaiqi | 2022 | China's Refractories2022，31，3： | 0 |

| 11 | Processing and Properties of Flexible Hot Gas Sealing Materials for Ceramic Membrane显示文摘Ceramic membranes are effective to reduce PM2. 5 emission when used for hot flue gas filtration. The properties of the sealing material play a decisive role in filtration efficiency. However,there are few studies on sealing materials for hot flue gas filtration above 700 ℃. This investigation was performed to develop flexible sealing materials which can be used for a long time at high temperatures. In order to obtain sufficient mechanical strength and continuous flexibility,three kinds of binders were selected as coating binders. The sealing materials based on high silica fiber fabric and aluminum silicate fiber fabric were successfully prepared. The effect of aging on mechanical properties and microstructural characteristics of the composites subjected to coating had been investigated by XRD,SEM and EDS. The results show that waterborne polyurethane( WPU) is a suitable coating binder for the sealing materials,which can be used for a long time at 1 000 ℃ and 700 ℃,respectively,without significant decrease in strength. However,the other two binders,aluminum dihydrogen phosphate and aluminum chromium phosphate will weaken the flexibility,resulting in frangibility and reducing sealing performance. The developed composites possess required thermo-stability and desired mechanical strength as flexible sealing materials,indicating their strong application possibility in hot flue gas filtration. | SUN Guangchao LIU Kaiqi LIU Qingzhu SI Kaikai | 2018 | China's Refractories2018，27，4： | 0 |
| 12 | Research Progress on Thermal Shock Behavior of Porous Ceramics显示文摘Thermal-mechanical coupling effect causes a large stress within porous ceramics at high temperatures,resulting in strength attenuation and product reliability decline.Thermal shock resistance is one of the key factors to characterize the reliability of ceramic materials under thermal-mechanical coupling effect.It is important to study the thermal shock resistance of the porous ceramics to evaluate their service performance and improve their service life.To better evaluate the effect of the thermal shock resistance on properties of the porous ceramics,the evaluation theories,experimental characterization methods and influencing factors about the thermal shock performance of the porous ceramics were reviewed in this paper,and some future research directions were prospected. | YAN Mingwei LIU Kaiqi ZHANG Jiayu SUN Guangchao LI Xiang SI Kaikai | 2022 | China's Refractories2022，31，1： | 0 |
