(Society of Physical Chemists of Serbia, 2018-09-28)
In this work, we present a simple green method for Ag and Au nanoparticles (NPs) synthesis in an aqueous medium. Ag and Au NPs were synthesized by chemical reduction method, using amino acid L-Methionine as reducing as ...
Raspodela ambijentalnog doznog ekvivalenta gama zračenja u ruralnim sredinama
(Društvo fizičara Srbije, Beograd, 2018-10-07)
Prirodno pozadinsko zračenje koje se registuje u normalnim uslovima potiče od kosmičkog zračenjai prirodnih radionuklida, a zavisi od geologije tla i nadmorske visine mernog mesta, pa je karakteristično za neki prostor. ...
Edukacija u korak sa savremenim istraživanjima radona
(Društvo fizičara Srbije, Beograd, 2018-10-07)
Sistematska merenja koncentracije radona se najčešće izvode na slučajnim uzorcima stambenih objekata. Međutim, škole se mogu pokazati kao pogodniji izbor, jer su uniformno raspoređene po celoj teritoriji područja ili ...
