To improve the catalytic performance of La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3)(LSCF)towards carbon soot,we utilized the impregnation method to incorporate Ag into the prepared LSCF *** conducted a series of characterization tests and evaluated the soot catalytic activity of the composite catalyst by comparing it with the LaCoO_(3) group,LaFeO_(3) group,and catalyst-free *** results indicate that the Ag-LSCF composite catalyst exhibits the highest soot catalytic activity,with the characteristic temperature values of 376.3,431.1,and 473.9℃at 10%,50%,and 90%carbon soot conversion,*** values are 24.8,20.2,and 23.1℃lower than those of the LSCF *** also shows that LSCF can improve the catalytic activity of soot after compounding with Ag,and reflects the necessity of using catalysts in soot combustion *** characterization and BET test show that Ag-LSCF has more abundant surface-adsorbed oxygen species,larger specific surface area and pore volume than LSCF,which also proves that Ag-LSCF has higher soot catalytic activity.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

本文报道聚乙二醇（PEG）及其单醚类化合物在咪唑N-烷基化反应中的催化效应,它是以组成聚乙二醇的（CH2CH2O）单元中的氧同Im-Na+形成离子对参与反应的.催化剂活性与分子量关系不大,主要取决于分子链中有效的（CH2CH2O）单元个数,并以不少于5的单元个数组成配合基元通过界面传递阴离子.在一定的催化剂浓度下,遵循假一级反应动力学关系.由此求得的不同碳链(C4～C16)烷基溴和咪唑发生N-烷基化反应的速度常数,显示碳链的空间结构对反应有明显的影响.咪唑和正-丁基溴发生N-正丁基化反应的活化能为12.4±0.5kcal/mol,还求取了该反应的活化参数△S、△H、△G,并与使用季铵盐和冠醚类化合物作相转移催化剂（PTC）的反应结果进行了对比.

This editorial examines a recent study that used radiomics based on computed tomography(CT)to predict the expression of the fibroblast-related gene enhancer of zeste homolog 2(EZH2)and its correlation with the survival of patients with hepatocellular carcinoma(HCC).By integrating radiomics with molecular analysis,the study presented a strategy for accurately predicting the expression of EZH2 from CT *** findings demonstrated a strong link between the radiomics model,EZH2 expression,and patient *** noninvasive approach provides valuable insights into the therapeutic management of HCC.
