what else interested him apart from chemistry?
Russian industry, technical issues in agricultural productivity, demographic issues, measuring the efficacy of chemical fertilizers, and promoted the merchant navy.
Dmitri Mendeleev
Beginning in the 1870s, he published widely beyond chemistry, looking at aspects of Russian industry, and technical issues in agricultural productivity. He explored demographic issues, sponsored studies of the Arctic Sea, tried to measure the efficacy of chemical fertilizers, and promoted the merchant navy.

He investigated the expansion of liquids with heat, and devised a formula similar to Gay-Lussac's law of the uniformity of the expansion of gases, while in 1861 he anticipated Thomas Andrews' conception of the critical temperature of gases by defining the absolute boiling-point of a substance

Dmitri Mendeleev [SEP] Activities beyond chemistry
Beginning in the 1870s, he published widely beyond chemistry, looking at aspects of Russian industry, and technical issues in agricultural productivity. He explored demographic issues, sponsored studies of the Arctic Sea, tried to measure the efficacy of chemical fertilizers, and promoted the merchant navy. He was especially active in improving the Russian petroleum industry, making detailed comparisons with the more advanced industry in Pennsylvania. Although not well-grounded in economics, he had observed industry throughout his European travels, and in 1891 he helped convince the Ministry of Finance to impose temporary tariffs with the aim of fostering Russian infant industries. In 1890 he resigned his professorship at St.
