Uduce duto two mu kirere (cenospheres) n'uduce duto tw'ibirahure (microspheres) twombi bikoreshwa mu nganda zitandukanye, harimo n'irangi ry'imodoka, kugira ngo byongere imiterere y'irangi ry'imodoka. Ariko, mu rwego rw'irangi ry'imodoka, uduce duto tw'ikirahure zikoreshwa cyane kurusha cenospheres.
Uduce duto tw'ikirahure ni utudomo duto tw’ibirahure duto, dukunze kongerwamo amarangi y’imodoka kugira ngo twongere imiterere yatwo. Ni tworoheje kandi dufite ubucucike buke, bifasha kugabanya uburemere bw’irangi muri rusange tudasize inyuma ingano yaryo. Ibi bishobora gutuma lisansi ikoreshwa neza kandi imodoka igakora neza. Ududomo duto tw’ibirahure natwo dufasha mu kuramba kw’irangi, kuko dushobora guteza imbogamizi zifasha mu gukumira ubushuhe no kwangirika.
Uduce tw'ikirereKu rundi ruhande, ni ibintu bikomoka ku gutwika amakara kandi bikoreshwa cyane cyane mu nganda nko mu bwubatsi, gucukura peteroli, no gukingira. Nubwo bifite imiterere yihariye, nko kurwanya ubushyuhe bwinshi, ntabwo bikunze gukoreshwa mu irangi ry'imodoka nk'udupira tw'ibirahure.
Muri make, utubumbe duto tw’ibirahure dukoreshwa cyane mu irangi ry’imodoka bitewe n’inyungu zatwo zihariye ndetse n’uko duhura n’uburyo bwo gusiga amarangi.
