The Mendeleev-Meyer force project.

Here we present the Mendeleev-Meyer Force Project which aims at tabulating all materials and substances in a fashion similar to the periodic table. The goal is to group and tabulate substances using nanoscale force footprints rather than atomic number or electronic configuration as in the periodic table. The process is divided into: (1) acquiring nanoscale force data from materials, (2) paramet...

From the Mendeleev periodic table to particle physics and back to the periodic table

We briefly describe in this paper the passage from Mendeleev’s chemistry (1869) to atomic physics (in the 1900’s), nuclear physics (in the 1932’s) and particle physics (from 1953 to 2006). We show how the consideration of symmetries, largely used in physics since the end of the 1920’s, gave rise to a new format of the periodic table in the 1970’s. More specifically, this paper is concerned with...

On a question by D. I. Mendeleev

D. I. Mendeleev’s Concept of Chemical Elements and the Principles of Chemistry

Dmitrii Ivanovich Mendeleev (1834-1907) was primarily a chemist even though he later worked in many other fields. One of his most important contributions to chemistry was the discovery in 1869 of the periodic law of the chemical elements, which is still a fundamental concept in modern chemistry. In 1905, shortly before his death, he listed what he considered his four main contributions to scien...
