It is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. Quantitative structure – activity relationship (QSAR) studies and quantitative structure –property relationship (QSPR) studies are active areas of chemical research that focus on the nature ofthis dependency. Topological indices are the numerical value associated with chemical constitution...

High-quality single crystals of EuAuAs were studied by means powder x-ray diffraction, magnetization, magnetic susceptibility, heat capacity, electrical resistivity and magnetoresistance measurements. The compound crystallizes with a hexagonal structure the ZrSiBe type (space group $P{6}_{3}/mmc$). It orders antiferromagnetically below 6 K due to moments divalent Eu ions. exhibits metallic beha...

With the motivation to investigate role of coal physical structure on adsorption performance reservoir, 18 different types samples with structures were collected from six profiles four production mines located at China. The characteristics CH 4 examined, and then experimental results fitted analyzed by Langmuir model potential (D-R D-A). prominent factors in terms capacity its adaptability disc...
