The major scientific results of the Institute include
An investigation of intramolecular dynamics of cellulose fibers, the character and
types of motion of marked cellulose chains independent from their origin,
temperature and humidity was completed. The correlation of marks, motion, and the
degree of correlation of molecular dynamics with mechanical solidity of fibers were
established by the studies.
The following have been worked out:

the use of solar cells as the base of organic-on-inorganic structures;
•
an acoustic analysis of materials during their chemical decomposition;
•
a method of growing molybdenum and tungsten bulk monocrystals from the
melt;

In the program of the investigation of experimental characteristic interactions of
cosmic rays with atmospheric nuclei in the field of energy higher than 10 eV
(experiment Pamir - Chakaltay), a gigantic super-family named "Tajikistan" was
registered, the central part of which has energy of 4.8x10 eV. This is the largest
super-family registered by a roentgen emulsion chamber in the world.
