Total petroleum hydrocarbons distribution and health risk assessment of soil in the Niš railway junction
(Naučno-stručno društvo za zaštitu životne sredine Srbije, ECOLOGICA, 2020)
A particularly high pollution level of total petroleum hydrocarbons (TPH) was observed in
the soil at the railway junction in the city of Niš (Serbia). The TPH level in most of the
studied soil samples exceeded the limit ...
Poboljšanje apsorpcionih svojstava TiO2 nanocevi pomoću CH3NH3PbBr3 perovskita kao fotosenzitivizatora / Improvement of absorption properties of TiO2 nanotubes by using CH3NH3PbBr3 perovskite as photosensitizer
(Savez inženjera i tehničara Srbije, 2022)
Organsko-neorganski perovskiti su privukli veliku pažnju istraživača zbog visoke apsorpcije u vidljivom
delu spektra i jeftine proizvodnje. Apsorbovanjem svetlosti dolazi do stvaranja para elektron-šupljina.
U cilju ...
