Izolovanje i karakterizacija mikroorganizama visokotolerantnih naperfluorovana jedinjenja. / Isolation and characterization of microorganisms highly tolerant to perfluorinated compounds
(Srpsko hemijsko društvo, 2023)
Razvoj hemijske industrije u prošlom veku pozitivno je uticao na životni standard, ali
je za sobom ostavio značajne količine toksičnih supstanci u životnoj sredini. Dugotrajne
organske zagađujuće supstance (Persistant ...
Uklanjanje sirove nafte iz vodene sredine – poređenje efikasnosti biougljeva i mikrobnih ćelija / Removal of crude oil from water environment – comparison between biochars and microbial cells
(Srpsko hemijsko društvo, 2023)
Cilj ispitivanja bio je da se uporedi efikasnost uklanjanja sirove nafte iz kontaminirane vodene sredine nakon mesec dana upotrebom biougljeva, biougljeva sa imobilizovanim mikrobnim ćelijama i samih mikrobnih ćelija.
Hydrolytic degradation of star-shaped poly(ε-caprolactone)s with different number of arms and their cytotoxic effects
(SAGE Publications, 2020)
Star-shaped polymers of biodegradable aliphatic polyester, poly(ε-caprolactone), PCL, with different number of arms (three, four, and six) were synthesized by ring-opening polymerization initiated by multifunctional alcohols ...
The effect of filler morphology on thermal characteristics of lignocellulose and metal powders composites / Uticaj morfologije punioca na termijske karakteristike kompozita lignoceluloze punjene metalnim prahovima
(Belgrade, Serbia : Engineering Society for Corrosion, 2015)
In this manuscript the results of experimental studies of the properties of composite materials based on lignocellulosic matrix (LC) filled with electrolytic copper powder and chemically obtained silver powder are presented. ...
Flotation Concentrations of Polymetallic Sulfides from Serbian Ore Deposits as Biohydrometalurgical Substrates: Laboratory Tests
(Faculty of Mining and Petroleum Engineering, Institute Technology of Bandung, 2015)
There are three ore deposits of polymetallic sulfide ores that are of economic value in Serbia. Only ore deposit "A" (in central part of Serbia) is mine in exploitation (underground and surface), including and floatation ...
Are Soil and Bioremediation in Focus of Sustainable Green Chemistry and Engineering?
(European association for chemical and molecular sciences (EuCheMS), 2015)
Usually the interest in, investigation of, development and application of principles of green chemistry and engineering are directed towards concrete chemical substances and processes and the same applies to fuels as one ...
Volatile Compounds of Nepeta nuda L. from Rtanj Mountain (Serbia)
(Horticulturae, 2022)
Unlike other studies that only determined the chemical composition of essential oils depending on their geographic origin, this research investigated the effect of weather conditions (temperature, precipitation, and ...
Improving the electrochemical performance of spray pyrolytic rare-earth cobaltite-based perovskite
(Belgrade : Serbian Ceramic Society, 2022)
Recently there is an effort to reach highly reversible and stable materials for energy storage
processes. Novel materials used in electrochemistry-based energy storage as a suitable
supports for noble ones, has been ...
Energy decomposition analysis of gauche preference in 2-haloethanol, 2-haloethylamine (halogen = F, Cl), their protonated forms and anti preference in 1-chloro-2-fluoroethane
(Royal Soc Chemistry, Cambridge, 2015)
2-Haloethanol and 2-haloethylamine (halogen = F, Cl) prefer gauche conformation. This preference is significantly increased upon protonation. Commonly used explanations are based on intramolecular hydrogen bonding and ...
Proces respiracije mikroorganizama u MFC sistemu tokom generisanja energije iz rečnog sedimenta / Respiration of microorganisms in the MFC system during the generation of energy from river sediment
(Srpsko hemijsko društvo, 2023)
Aktivnost mikroorganizama je direktno povezana sa njihovim disanjem. U prisustvu
velikih količina biodostupne organske supstance, brzina disanja mikroorganizama je veća.
Praćenje disanja je postalo bitan parametar u ...
