Zinc-ion hybrid supercapacitors (ZHSs), which combine the superiority of batteries and supercapacitors, will become a new development direction in the field of energy storage. The development of ZHSs with high capacity and high stability can be further promoted by heteroatom doping or structural modification of cathode materials. Herein, N,O,P co-doped porous carbon materials were synthesized by a facile method using coal tar pitch as precursor, aluminum phosphate as template, and sodium hydroxide as activator. Due to the high specific surface area and abundant micropores, the heteroatom-doped porous carbon materials were employed as cathode for aqueous ZHSs to study the electrochemical performance. Benefitted from the rich micropores and heteroatom doping, the porous carbon electrodes exhibit an outstanding electrochemical performance and deliver a large specific capacitance of 113.3 mA h g􀀀 1 at 0.1 A g􀀀 1. In addition, the porous carbon electrode shows a high energy density of 64.9 Wh kg􀀀 1 and a high power density of 1.23 kW kg􀀀 1, which outperforms most aqueous ZHS energy storage systems previously reported. Interestingly, after 5000 cycles at 1 A g􀀀 1, the specific capacity is about 36% higher than the original capacity and the coulomb efficiency still remains nearly 100%. The article may provide a new insight into exploring cathode materials for high-performance aqueous rechargeable zinc-ion energy storage devices.

采集燃煤电厂的运行数据,建立水露点与酸露点的物理模型,并通过实验验证模型的正确性,对锅炉尾部系统中影响露点的因素进行分析,在大数据计算分析的基础上,分析各因素对空预器水露点、酸露点的影响。结果表明:发电机组负荷和燃煤的空干基水分的增大均会使水露点和酸露点温度上升;燃煤的全硫分对水露点无影响,但会提高酸露点温度;环境温度通过改变空预器壁面的温度影响水露点与酸露点温度;脱硝系统和空预器均会使水露点温度稍微降低,但脱硝时酸露点温度稍微升高。

RPTA(regulatory particle triple-A ATPase)家族与植物的生长发育、激素调控和逆境胁迫反应密切相关。本研究一共鉴定到33个OsRPTA基因家族成员,并分析了其基因位置、基因结构、motif组成和启动子顺式作用元件等信息。随后,利用水稻CREP数据库下载的数据,分析了OsRPTA基因家族成员的全生育期组织表达模式。发现大部分OsRPTA基因在穗、胚乳和愈伤组织中具有较高的表达水平。β-D-葡萄糖苷酸酶(GUS)染色进一步显示,基因成员OsRPTA18主要在叶枕、根、叶、叶鞘、茎节、内稃和外稃的维管束等部位表达。亚细胞定位结果显示OsRPTA18蛋白定位于细胞核。通过CRISPR/Cas9基因编辑获得了突变体材料osrpta18-1和osrpta18-2。与中花11相比,突变体植株的株高、叶倾角变小,粒宽和千粒重降低。组织切片结果表明,突变体osrpta18旗叶倾角变小是由于叶枕近轴面厚壁细胞增殖,导致近轴面与远轴面细胞和维管束的不对称性减弱。本研究有助于了解水稻RPTA基因家族功能,并为利用OsRPTA18基因培育理想株型的水稻品种提供参考。

The raphe nucleus is critical for feeding, rewarding and memory. However, how the heterogenous raphe neurons are molecularly and structurally organized to engage their divergent functions remains unknown. Here, we genetically target a subset of neurons expressing VGLUT3. VGLUT3 neurons control the efficacy of spatial memory retrieval by synapsing directly with parvalbumin-expressing GABA interneurons(PGIs) in the dentate gyrus. In a mouse model of Alzheimer's disease(AD mice),VGLUT3→PGIs synaptic transmission is impaired by ETV4 inhibition of VGLUT3 transcription. ETV4 binds to a promoter region of VGLUT3 and activates VGLUT3 transcription in VGLUT3 neurons. Strengthening VGLUT3→PGIs synaptic transmission by ETV4 activation of VGLUT3 transcription upscales the efficacy of spatial memory retrieval in AD mice. This study reports a novel circuit and molecular mechanism underlying the efficacy of spatial memory retrieval via ETV4 inhibition of VGLUT3 transcription and hence provides a promising target for therapeutic intervention of the disease progression.
