Set Aside when Building the Periodic Table 150 Years ago, are Rare Earths any better considered by Chemists in the 21st Century?A hundred and fifty years ago, the Rare Earths posed a serious problem to Mendeleyev because of their very similar chemical properties, although their atomic mass ...
The first elements of the periodic table is hydrogen and its molecular form is dihydrogen (H(2)). When H(2) reacts with O(2), Water is formed . Water is a liquid at room temperature. When liquied water freezes, it expands to form ice.

An AFM probe was coated with S. epidermidis cells and used to probe a gold slide that had been coated with FBS or another protein, fibronectin (FN). These experiments show that AFM and QCM-D can be used in complementary ways to study the complex interactions between bacteria, proteins, ...

Unlike the authors' findings, in our case the epidemiologic dimension was the least considered in practice. Special mention should be made of our findings about the sociocultural dimension. Although it was present with almost the similar weight in both theory and practice of the analyzed works, ...
