Moprofesa Knox T.

Dr. Moghaddam o itse: “Re bontšitse ka mokhoa o ikhethang o ikopanyelitseng oa mosaic ea odara ea GO nanoplatelet, e ntlafatsang haholo boiteko ba lilemo tse leshome ba ho etsoa ha lera la graphene.”Ke sethala se sebetsang se ka ntlafatsang dialysis ea bosiu bo bobebe lapeng. ”Hajoale Dr. Moghaddam o ntse a sebetsa ho nts'etsopele ea li-microchips tse sebelisang li-membrane tsa GO tse ncha, tse tla atametsa lipatlisiso haufi le 'nete ea ho fana ka lisebelisoa tse aparoang tsa hemodialysis bakeng sa bakuli ba lefu la liphio.
