Zaradi vse večje onesnaženosti površinskih vod z različnimi mikro-onesnažili, je iskanje naprednejših tehnologij za obdelavo odpadnih vod ključnega pomena. Nekatere tehnologije, kot na primer kavitacija, se na tem področju že uveljavljajo. Želja po doseganju boljših sinergijskih učinkov pri manjši r ...

V diplomskem delu smo analizirali površino bukovega (Fagus sylvatica L.) in smrekovega (Picea abies (L.) Karst.) lesa, po obdelavi z dielektrično barierno razelektritveno (DBD) plazmo s plavajočo elektrodo. Znano je, da na učinek obdelave površin lesa s plazmo vplivajo zunanji (lastnosti materiala i ...

V diplomskem delu smo analizirali površino smrekovega (Picea abies (L.) Karst.) lesa, po obdelavi z dielektrično barierno razelektritveno (DBD) plazmo in premazovanju površin. Uporabili smo transparentna brezbarvna premazna sredstva (na osnovi organskih topil in vode) ter okolju prijaznejše sredstvo ...

Vpliv obdelave z dielektrično barierno razelektritveno (DBD) plazmo na dielektrične lastnosti smrekovega lesa (Picea abies (L.) Karst.) smo raziskovali z dielektrično analizo. Pri različnih frekvencah smo določili dielektrično konstanto in faktor dielektričnih izgub. Nastale spremembe na vzorcih lam ...
