| 1 | Mechanical and dielectric properties of porous and wave-transparent Si3N4–Si3N4 composite ceramics fabricated by 3D printing combined with chemical vapor infiltration显示文摘Porous Si3N4–Si3N4 composite ceramics were fabricated by 3D printing combined with low-pressure chemical vapor infiltration(CVI).This technique could effectively improve the designability of porous Si3N4 ceramics and optimize the mechanical and dielectric properties.The effects of process parameters including the deposition time and heat treatment on the microstructure and properties of porous Si3N4–Si3N4 composite ceramics were studied.The study highlights following:When CVI processing time was increased from 0 to 12 h,the porosity decreased from68.65%to 26.07%and the density increased from 0.99 to 2.02 g/cm3.At the same time,the dielectric constant gradually increased from 1.72 to 3.60;however,the dielectric loss always remained less than0.01,indicating the excellent electromagnetic(EM)wave-transparent performance of porous Si3N4–Si3N4 composite ceramics.The maximum flexural strength of 47±2 MPa was achieved when the deposition time attained 6 h.After heat treatment,the porosity increased from 26.07%to 36.02%and the dielectric constant got a slight increase from 3.60 to 3.70 with the dielectric loss still maintaining lower than 0.01.It has been demonstrated that the porous Si3N4–Si3N4 composite ceramics are a promising structural and EM wave-transparent material suitable for high temperature service. | Zanlin CHENG Fang YE Yongsheng LIU Tianlu QIAO Jianping LI Hailong QIN Laifei CHENG Litong ZHANG | 2019 | Journal of Advanced Ceramics2019，8，3： | 10 |

| 4 | Electrochemical Study on the Change in Valency of Niobium Oxide in the MnO-SiO_2-Nb_2O_5 System显示文摘Change in valency of Nb-oxide in MnO-SiO2-Nb2O5 system was studied with the electrochemical method using ZrO2 asthe solid electrolyte.Thermodynamic analysis has shown that the only possible reaction that could take place at the working elec-trode is:2(Nb2O5)=2(Nb2O4)+O2 with the a0 values experimentally evaluated,values of a Nb2O:/a Nb2O:were calculated andisoactivity-ratio curves drawn in MnO-SiO2-Nb2O5 triangles at 1418 and 1585K.The simultaneous existence of tetra-andpenta-valent Nb mineral constituents in industrial Nb-bearing slags was thus verified experimentally. | Tan Zanlin Wei Shoukun University of Science and Technology Beijing | 1990 | Rare Metals1990，10，1： | 0 |
| 5 | Chlorination of Nb-Bearing Slag from Baotou Hot Metal and Mechanism on Its Demanganification显示文摘Nb-bearing slag from Baotou hot metal was chlorinated in the solid state with molten CaCl2 under vacuum,96~98% MnO or FeO being thus volatilized.By reducing the chloridized residue under addition of flux,ferroniobium withabout 60% Nb was successfully made.Kinetic study of chlorination of synthetic MnO-Nb2O5-SiO2 andFeO-Nb2O5-SiO2 slag systems was conducted,and a non-reacting core model for the demanganification with free useof activity was formulated and the rate-controlling step was explained. | Tan, Zanlin Wei, Shoukun Zhu, Yuankai | 1989 | Rare Metals1989，9，1： | 0 |
| 6 | The SlTPL3–SlWUS module regulates multi-locule formation in tomato by modulating auxin and gibberellin levels in the shoot apical meristem显示文摘Malformed fruits depreciate a plant’s market value.In tomato(Solanum lycopersicum),fruit malformation is associated with the multi-locule trait,which involves genes regulating shoot apical meristem(SAM)development.The expression pattern of TOPLESS3(SITPL3)throughout SAM development prompted us to investigate its functional significance via RNA interference(RNAi)and clustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease 9(Cas9)-mediated gene editing.Lower SITPL3 transcript levels resulted in larger fruits with more locules and larger SAMs at the 5 d after germination(DAG5)stage.Differentially expressed genes in the SAM of wild-type(WT)and SITPL3-RNAi plants,identified by transcriptome deep sequencing(RNA-seq),were enriched in the gibberellin(GA)biosynthesis and plant hormone signaling pathways.Moreover,exogenous auxin and paclobutrazol treatments rescued the multi-locule phenotype,indicating that SITPL3 affects SAM size by mediating auxin and GA levels in the SAM.Furthermore,SITPL3 interacted with WUSCHEL(SIWUS),which plays an important role in SAM size maintenance.We conducted RNA-seq and DNA affinity purification followed by sequencing(DAP-seq)analyses to identify the genes regulated by SITPL3 and SIWUS in the SAM and to determine how they regulate SAM size.We detected24 overlapping genes regulated by SITPL3 and SIWUS and harboring an SIWUS-binding motif in their promoters.Furthermore,functional annotation revealed a notable enrichment for functions in auxin transport,auxin signal transduction,and GA biosynthesis.Dual-luciferase assays also revealed that SITPL3 enhances SIWUS-mediated regulation(repression and activation)of SIPIN3 and SIGA2 ox4 transcription,indicating that the SITPL3-SIWUS module regulates SAM size by mediating auxin distribution and GA levels,and perturbations of this module result in enlarged SAM.These results provide novel insights into the molecular mechanism of SAM maintenance and locule formation in tomato and highlight the SITPL3-SIWUS module as a key regulator. | Shiwei Song Binbin Huang Zanlin Pan Qiuxiang Zhong Yinghua Yang Da Chen Lisha Zhu Guojian Hu Mi He Caiyu Wu Mohammed Zouine Riyuan Chen Mondher Bouzayen Yanwei Hao | 2022 | Journal of Integrative Plant Biology2022，64，11： | 0 |
