(Elsevier B.V., 2015-02-16)The properties of neutral molecular Cs2Cl2, Cs3Cl3 and Cs4Cl4 and the positively charged ionic clusters Cs4Cl3+ and Cs5Cl4+ existing in vapor over cesium chloride have been studied. The DFT method with B3LYP5 and B3P86 ... -
Molecular and Ionic Clusters of Rubidium Fluoride: Theoretical Study of Structure and Vibrational Spectra
(Science Publishing Group, 2015-10-19)In this study, the geometrical structure and vibrational spectra of the trimer molecule Rb3F3 and ionic clusters Rb2F + , RbF2 – , Rb3F2 + , and Rb2F3 – were studied by density functional theory (DFT) with hybrid ... -
A Molecular Investigation of the Solvent Influence on Inter- and Intra-Molecular Hydrogen Bond Interaction of Linamarin
(MDPI, 2022-02-11)Linamarin has been reported to have anticancer activities; however, its extraction and isolation using different solvents yield a low amount. Therefore, understanding the physical prop‐ erties, such as solvents’ solubility, ... -
Morphological and Chemical Composition Characterization of Commercial Sepia Melanin
(Science and Education Publishing, 2015)Melanins are difficult to characterize because of their intractable chemical properties and the heterogeneity in their structural features. Melanin pigments, in fact, are composed of many different types of monomeric units ... -
Multi-variate regression analysis of lake level variability: A case of semi-closed, shallow rift valley lake in Northern Tanzania
(Elsevier, 2022)Lakes are very important for domestic use, commercial purposes, and ecosystem sustenance; nevertheless, studies on how different stressors influence water resources are limited, posing challenges in the planning and ... -
