Dedication
Prof. Nina N. Mofa (04.10.1946–16.08.2021)
Our sorrow today is as intense as our respect and love for
Nina N. Mofa. Prof. Mofa lived a bright and worthy life and was
a true intellectual, a person of brilliant intellect and great
erudition. Since 1988, she worked at the Institute of Combustion
Problems in various positions as a senior researcher, chief
researcher, and head of the Laboratory of Mechanochemical
Processes and Combustion Problems. She actively participated
in the scientific and administrative life at the Institute. Her
main scientific interest was in the study of the processes of
creating nanostructured microcomposite systems by thermal
and mechanochemical treatment. She authored more than
300 publications, including scientific articles and abstracts, and
4 monographs and held 28 certificates of authorship and patents
of Kazakhstan and Russia. In 2014, she was awarded the badge
of the Ministry of Industry and New Technologies of the Republic
of Kazakhstan.
The directorate and the staff of the Institute of Combustion
Problems express their deep condolences on the departure of
Prof. Mofа, the outstanding scientist and unique organizer of
science. May the departed soul rest in peace and be a driving force
for all of us.
