| 1 | Construction of hydrangea-like core-shell SiO_(2)@Ti_(3)C_(2)T_(x)@CoNi microspheres for tunable electromagnetic wave absorbers显示文摘Ti_(3)C_(2)T_(x)MXene shows great potential in the application as microwave absorbers due to its high attenuation ability.However,excessively high permittivity and self-stacking are the main obstacles that constrain its wide range of applications.To tackle these problems,herein,the microspheres of SiO_(2)@Ti_(3)C_(2)T_(x)@CoNi with the hydrangea-like core-shell structure were designed and prepared by a combinatorial electrostatic assembly and hydrothermal reaction method.These microspheres are constructed by an outside layer of CoNi nanosheets and intermediate Ti_(3)C_(2)T_(x)MXene nanosheets wrapping on the core of modified SiO_(2),engendering both homogenous and heterogeneous interfaces.Such trilayer SiO_(2)@Ti_(3)C_(2)T_(x)@CoNi microspheres are“magnetic microsize supercapacitors”that can not only induce dielectric loss and magnetic loss but also provide multilayer interfaces to enhance the interfacial polarization.The optimized impedance matching and core-shell structure could boost the reflection loss(RL)by electromagnetic synergy.The synthesized SiO_(2)@Ti_(3)C_(2)T_(x)@CoNi microspheres demonstrate outstanding microwave absorption(MA)performance benefited from these advantages.The obtained RL value was-63.95 dB at an ultra-thin thickness of 1.2 mm,corresponding to an effective absorption bandwidth(EAB)of 4.56 GHz.This work demonstrates that the trilayer core-shell structure designing strategy is highly efficient for tuning the MA performance of MXene-based microspheres. | Huanhuan Niu Xuewen Jiang Yongde Xia Hailong Wang Rui Zhang Hongxia Li Bingbing Fan Yanchun Zhoua | 2023 | Journal of Advanced Ceramics2023，12，4： | 3 |
| 2 | Poaceae Orthologs of Rice OsSGL,DUF1645 Domain-Containing Genes,Positively Regulate Drought Tolerance,Grain Length and Weight in Rice显示文摘Grain yield is a polygenic trait that can be influenced by environmental factors and genetic compositions at all plant growth stages.Currently,the molecular mechanisms behind the coordination of the interaction between grain yield-related traits remain unknown.In this study,we characterized the function of four STRESS_tolerance and GRAIN_LENGTH(Os SGL)Poaceae ortholog genes that are transcribed into DUF1645 domain-containing proteins in relation to the grain length,grain weight,and drought stress-tolerance of rice.The transgenic plants with overexpressing or heterologous high levels of Poaceae OsSGL ortholog genes exhibited longer grain size than the wild type plants.Larger cells were seen in panicles of the four transgenic lines with paraffin sectioning and scanning electron microscopy analyses.In addition,four Poaceae OsSGL ortholog genes positively affected the drought tolerance of rice.Four transgenic plants displayed higher resistance to drought stress at the seedling and vegetative stages.RNA-sequencing and qRT-PCR results indicated that over-or heterologous-expression of four Poaceae OsSGL ortholog genes also affected the transcriptome of rice plants.These genes may play a role in auxin and cytokinin biosynthesis and their transduction pathways.Taken together,these results suggested that the four OsSGL orthologs have a conserved function in the regulation of stress-tolerance and cell growth by modulating hormonal biosynthesis and signaling. | LIU Kai LI Minjuan ZHANG Bin YIN Xuming XIA Xinjie WANG Manling CUI Yanchun | 2022 | Rice science2022，29，3： | 2 |

| 5 | Fabrication of multi-anionic high-entropy carbonitride ultra-high-temperature ceramics by a green and low-cost process with excellent mechanical properties显示文摘As a new category of ultra-high-temperature ceramics(UHTCs),multi-anionic high-entropy(HE)carbonitride UHTCs are expected to have better comprehensive performance than conventional UHTCs.However,how to realize the green and low-cost synthesis of high-quality multi-anionic HE carbonitride UHTC powders and prepare bulk ceramics with excellent mechanical properties still faces great challenges.In this work,a green,low-cost,and controllable preparation process of(Ti_(0.2)Zr_(0.2)Hf_(0.2)Nb_(0.2)Ta_(0.2))C,N_(1-x) powders is achieved by sol-gel combined with the carbothermal reduction/nitridation method for the first time.The as-synthesized(Ti_(0.2)Zr_(0.2)Hf_(0.2)Nb_(0.2)Ta_(0.2))C_(x)N_(1-x) powders possess high compositional uniformity and controllable particle size.In addition,the obtained bulk ceramics prepared at 1800℃exhibit superior fracture toughness(Kic)of 5.39±0.16 MPa·m^(1/2) and high nanohardnesof 35.75±1.23 GPa,lastic modulus(E)of 566.70±8.68 GPa,and flexural strength of 487±41 MPa.This study provides a feasible strategy for preparing the high-performance HE carbonitride ceramics in a more environmentally friendly and economical manner. | Liansen Xia Shun Dong Jianqiang Xin Kaixuan Gui Peitao Hu Yongshuai Xie Dongdong Yang Xinghong Zhang Yanchun Zhou | 2023 | Journal of Advanced Ceramics2023，12，6： | 1 |

| 7 | A novel methodology for complex part motion planning显示文摘A motion planning strategy for the assembly task of inserting a dissymmetrical T-shaped part into a C-shaped slot is presented. The coarse motion planning strategy is expounded by geometric reasoning. A medial axis diagram decreases the unnecessary configuration states and optimizes the planning strategy. Due to the uncertainties, force sensing and force control is indispensable for motion planning. Combining the coarse motion planning strategy with fine motion planning strategy, the task of assembling a dissymmetrical T-shaped part can be completed successfully. | Xia Yanchun(夏妍春) Yin Yuehong Chen Zhaoneng | 2005 | High Technology Letters2005，11，3： | 1 |
