Utilization of the integrated process of supercritical extraction and impregnation for incorporation of helichrysum italicum extract into corn starch xerogel
(Savez hemijskih inženjera, Beograd, 2018)
Supercritical CO2 extraction of Helichrysum italicum and impregnation of starch xerogels with the extract by using an integrated scCO(2) extraction and impregnation process were performed at 350 bar and 40 degrees C in ...
Aerogels - II. Applications in catalysis / Aerogeli - II. Primeria u katalizi
(Association of the Chemical Engineers of Serbia, 2002)
Sol-gel synthesis, and the resulting materials (xerogels and aerogels) are finding increasing application in the synthesis of catalysts, due to their unique characteristics. The most important features of the sol-gel process ...
Immobilization of fish chromatophores for use as a micro-biosensor for biological toxins / Imobilizacija hromatofora riba radi korišćenja kao biosenzor za biološke toksine
(Association of the Chemical Engineers of Serbia, 2003)
Chromatophores isolated from the Siamese fighting fish, Betta splendens, represent a class of living cells that provide a vivid color response to microbial pathogens and environmental toxins. The selection of the most ...
Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of the Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...
