Kinetic and isotherm studies for the biosorption of nickel ions by jute fabrics
(Journal of the Serbian Chemical Society, 2021)
Raw jute fabric was chemically modified with 1 % NaOH for 30 min, 17.5 % NaOH for 5 min or with 0.7 % NaClO2 for 30 and 60 min to study the influence of changes in the chemical composition of the fabrics and quantity of ...
Kardiovaskularni lekovi u rečnoj vodi Beograda
(Akademija tehničkih strukovnih studija Beograd, 2021)
Glavni put dospevanja lekova u životnu sredinu su komunalne otpadne vode. U regionu
Beograda, otpadne vode se direktno ispuštaju u reke Savu i Dunav, što negativno utiče na kvalitet
rečne vode. Zbog svoje postojanosti i ...
MEHANIČKA SVOJSTVA ARAMIDNIH KOMPOZITA / MECHANICAL PROPERTIES OF ARAMID COMPOSITES
(Srpsko hemijsko društvo, 2021)
Materijali u vidu tkanina koje se proizvode
od vlakana velike žilavosti koriste se u antibalističkoj zaštiti zbog svoje male gustine, velike
otpornosti na udar i velikog kapaciteta apsorbovanja energije. Poslednjih godina ...
Eksperimentalno određivanje gustina linalola, alfa-pinena i beta-pinena na visokom pritisku / Experimental determination of linalool, α-pinene and β-pinene densities at high pressure
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2021)
U cilju smanjenja zagađenja na globalnom nivou poslednjih godina aktuelna je tema zamene fosilnih goriva nekim novim biogorivima. Terpeni, koji su sastavni delovi biljaka, mogu se koristiti u ove svrhe kao dodatak standardnim ...
Аntimicrobial activity of oxidized cotton fabric impregnated with Cu-based nanoparticles
(Portugal : University of Minho, 2021)
This study discusses the antimicrobial activity of cotton (CO) fabric oxidized with NaIO4/NaClO2
prior to in situ synthesis of Cu-based nanoparticles (NPs). Carboxyl groups generated by oxidation
of cellulose were utilized ...
Mesomorphism of novel stilbene-based bent-core liquid crystals
(Liquid Crystals, 2021)
A series of asymmetric bent-core liquid crystals, bearing the stilbene moiety in the side wing, was synthesised and characterised. Structural modifications of the non-stilbene wing resulted in formation of various mesophases. ...
Biodegradation of cotton fabric modified with polycarboxylic acids and CuO/Cu2O nanoparticles in soil and compost
(Portugal : University of Minho, 2021)
Nano-finishing of textiles with Cu-based nanoparticles (NPs) is continually gaining scientific attention
due to their extraordinary antimicrobial activity and inexpensive precursor salts. After exploitation,
such textile ...
Removal of Nickel Ions from Aqueous Solutions by 2-Hydroxyethyl Acrylate/Itaconic Acid Hydrogels Optimized with Response Surface Methodology
(Gels, 2021)
The adsorption of Ni2+ ions from water solutions by using hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA) was studied. Hydrogel synthesis was optimized with response surface methodology (RSM). The ...
Phenolic Compounds and Antioxidant Properties of Field-Grown and In Vitro Leaves, and Calluses in Blackberry and Blueberry
(Horticulturae, 2021)
The aim of this study was to evaluate the content and profile of the phenolic compounds (PCs) and antioxidant properties of field-grown leaves, in vitro leaves and in vitro callus cultures of the blackberry 'Cacanska ...
The effects of pollinizers on pollen tube growth and fruit set of European plum (Prunus domestica L.) in a Nordic climate
(Scientia Horticulturae, 2021)
Norwegian plum production is characterized by climatic limitations, different flowering time, deficiently of wholly-adapted cultivars and appropriate pollen donors for cultivars that can be grown in this region. This study ...
