10th International Symposium on Group IV, V, VI elements.

For the first time the international symposium on group V elements included group IV and VI elements: titanium chromimu halfnium and chromium, molybdenum, and tungsten. This symposium series began in 1992 and it was originally dedicated to niobium compounds [1]. Three years later, again in Tokyo, the second symposium remained with niobium materials and catalysts [2]. After another three years, the symposium shifted to Rio de Janeiro and expanded to include vanadium and tantalum group V elements [3]. The symposium has been held every three years thereafter in Spain [4,5] , Hancock Massachusetts [6] , Poland [7] , Italy [8] , and New Delhi in 2019 [9]. Due to COVID the 10th symposium, held in Montreal, was delayed by one year and it was expanded to include Group IV and VI elements. [ABSTRACT FROM AUTHOR]
