Problems and prospects of the development of Ukrainian art (realities of martial law)

This article examines the problems of Ukrainian artistic space that emerged as a result of the Russian-Ukrainian war, and the prospects for its development in the future. The purpose of this research work is to thoroughly investigate the ways of development of Ukrainian art in the realities of wartime and the formation of new features of national identity in the European cultural space.

Unexpected isomerization of oxetane-carboxylic acids

We unexpectedly discovered that popular oxetane-carboxylic acids are intrinsically unstable. They easily isomerize into lactones under storage at rt, or under slight heating. Chemists should keep in mind the high instability of these common molecules, as this could dramatically affect the reaction yields and lead to negative results (especially in those reactions that require heating)
