Stark spectroscopy has been applied to a wide range of molecular systems and materials. A generally useful method for obtaining electronic and vibrational Stark spectra that does not require sophistic...
Over the last few decades, quantum chemistry has progressed through the development of computational methods based on modern digital computers. However, these methods can hardly fulfill the exponentia...
A complete chemical module has been developed for use in the Meso-NH three-dimensional cloud resolving mesoscale model. This module includes gaseousand aqueous-phase chemical reactions that are anal...
Polyketides are a broad class of natural products that have received attention from the scientific community because they are a rich mine of bioactive structures. The common thread that binds the clas...
The philosophy of chemistry has been sadly neglected by most contempory literature in the philosophy of science. This paper argues that this neglect has been unfor-tunate and that there is much to be ...
By the 1960s many (perhaps most) philosophers had adopted ‘physicalism’ ─ the view that physical causes fully account for mental activities. However, controversy persists about what count as ‘physical...
261. Chemical Equivalents.- The proportions, or quantities by weight, in which different substances unite to form definite chemical compounds, are called Chemical Equivalents (from cequus, equal, and ...
Mineral chemistry of biotite, chlorite and epidote associated with the granitoid ore body of the Malanjkhand copper-molybdenum deposit have been studied to constrain temperature, oxidation and sulfida...
应用随机森林方法、开放源代码软件-CDK(Chemistry Development Kit)描述符与170个化合物的训练数据集[其中96个为磷糖蛋白(P-gp)底物], 建立了P-gp底物的识别模型. 研究了CDK描述符与P-gp底物识别的关系, 结果表明, 原子极化性和电荷偏面积等分子属性对P-gp底物识别起到重要作用. 该模型对训练集的预测正确率为99.42%; 对外部测试集(42个化合物,...
摘要 The title compounds were synthesized by taking advantage of the Martin ligand. Their structures were determined by X-ray crystallography. Pentacoordinate thiasiliranides were hydrolyzed to give the...
To achieve the synthesis of azasugar derivatives with the utilization of singlet oxygen, pyridine was used as the starting material. The reduction of pyridine followed by a singlet oxygen reaction aff...
