利用热天平对富氧气氛下CaCO3煅烧产物碳酸化特性进行了实验研究,分析发现,温度是决定碳酸化反应速率快慢及最终转化率高低的关键因素,在一定的温度范围内,随着温度的升高,碳酸化反应速率加快,最终转化率提高。同时发现,CO2浓度增加可加快化学反应阶段速率,但最终转化率相差不大。对CaO活化能的计算,采用了分阶段计算。不同CO2浓度的活化能相差不大,而且产物层控制阶段的活化能都比化学反应控制阶段的活化能大很多。

Colorectal carcinoma(CRC),the third most commonly diagnosed cancer,accounts for 9.7%of all newly diagnosed cancer cases and 9.4%of cancer-related deaths globally.1 Recent studies have demonstrated that post-transcriptional RNA modifications,such as N^(6)-methyladenosine,N^(5)-methylcytosine,and N^(7)-methylguanosine,play critical roles in the regulation of mRNA stability and translation,primary microRNA processing,and lncRNA-protein complex that contributes to the progression of human cancer.

利用静态暗箱/气相色谱法对三江平原毛果苔草沼泽4个生长阶段(开花期、果熟期、果后营养期和枯萎期)进行CH4排放通量的日变化观测实验。结果表明,毛果苔草沼泽这4个生长阶段CH4排放通量的日变化规律不一致,开花期时表现为无明显规律,果熟期、果后营养期和枯萎期时其变化均为单峰曲线,峰值分别出现在9时、19时和13时。CH4排放通量的日变化与温度的相关性不明显。对比各生长阶段CH4的日平均通量值发现,果熟期和果后营养期CH4日均通量大,而开花期和枯萎期的日均通量明显减小。从整个生长季来看,CH4排放通量的日变化与气温、水温、5cm地温、10cm地温、15cm地温和20cm地温均呈极显著的正相关关系。温度是影响CH4排放通量变化的主要因素。

Indium oxide(In_(2)O_(3)),as a promising candidate for CO_(2)hydrogenation to C_(1) products,often suffers from sintering and activity decline,closely related to the undesirable structural evolution under reaction *** on the comprehension of the dynamic evolution,this study presents an efficient strategy to alleviate the agglomeration of In_(2)O_(3)nanoparticles by the surface decoration with highly dispersed silica species(SiO_(x)).Various structural characterizations combined with density functional theory calculations demonstrated that the sintering resulted from the over-reduction,while the enhanced stability originated from the anchoring effect of highly stable In-OSi bonds,which hinders the substantial formation of metallic In(In^(0))and the subsequent agglomeration.0.6Si/In_(2)O_(3)exhibited CO_(2)conversion rate of10.0 mmol g^(-1)h^(-1)at steady state vs.3.5 mmol g^(-1)h^(-1)on In_(2)O_(3)in CO_(2)*** steady-state activity was also achieved on Pd-modified *** to the traditional Pd/In_(2)O_(3)catalyst,the methanol production rate of Pd catalyst supported on 0.6Si/In_(2)O_(3)was enhanced by 23%,showing the potential of In_(2)O_(3)modified by SiO_(x)in serving as a platform *** work provides a promising method to design new In_(2)O_(3)-based catalysts with improved activity and stability in CO_(2)hydrogenation.
