Efficiency of phosphorus accumulation by plankton, periphyton developed on submerged artificial substrata and metaphyton: in-situ observation in two shallow ponds
(Springer Science and Business Media LLC, 2020)
Phosphorus overenrichment of shallow ponds prevailing in wetlands leads to their eutrophication causing the collapse of those vulnerable habitats. The potential of phosphorus accumulation by periphyton developed on artificial ...
Microstructure and thermal properties of Bi-Sn eutectic alloy
(München : Carl Hanser Verlag, 2020)
Alloys based on Sn and Bi are considered to be one of the best soft lead-free solders due to their low melting temperature and low price. In addition, Bi-Sn alloy with a eutectic composition represents a promising candidate ...
Antibiotic production by Streptomyces hygroscopicus CH-7 in medium containing Schiff base complexes / Продукција антибиотика помоћу Streptomyces hygroscopicus CH-7 у хранљивим подлогама са комплексима шифових базa
(Association of the Chemical Engineers of Serbia, 2019)
Influence of a modified media on Hexaene H-85 and Azalomycine B production by Streptomyces hygroscopicus CH-7 was investigated. The amino acid L-tryptophan, as a nitrogen source, was replaced with isatin-3-thiosemicarbazone ...
Spectroscopic and quantum chemical elucidation of newly synthesized 1-aryl-3-methyl-3-phenylpyrrolidine-2,5-diones as potential anticonvulsant agents
(Belgrade : Association of the Chemical Engineers of Serbia, 2019)
Novel succinimide derivatives were synthesized from 3-methyl-3-phenylsuccinic acid and substituted anilines under solvent-free conditions by using microwave irradiation. All obtained compounds were characterized by ultraviolet ...
Comparative numerical and experimental investigation of static and dynamic characteristics of composite plates
(Springer, 2019)
In order to investigate both static and dynamic characteristics of composite plates and validate a contemporary, non-invasive experimental technique a comparative experimental and numerical analysis was performed. Three, ...
Horse chestnut (Aesculus hippocastanum L.) seed fatty acids, flavonoids and heavy metals plasticity to different urban environments
(Elsevier, 2020)
Horse chestnut (Aesculus hippocastanum L.) is a deciduous tree which is widely used on urban green spaces in Serbia. Also, the seed of horse chestnut is an important raw material in pharmaceutical industry, owing to its ...
Phenolic composition and DPPH radical scavenging activity of plum wine produced from three plum cultivars
(Journal of the Serbian Chemical Society, 2019)
Plum wines made from two cultivars of Prunus domestica L. (Požegača and Crvena ranka) and one cultivar of Prunus insititia L. (Trnovača) were evaluated for their total phenolic and anthocyanin contents. LC–MS/MS analysis ...
Theoretical modeling of sorption of metal ions on amino-functionalized macroporous copolymer in aqueous solution
(Springer, 2019)
With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. ...
A novel PGA/TiO2 nanocomposite prepared with poly(γ-glutamic acid) from the newly isolated Bacillus subtilis 17B strain / Нови ПГК/TiO2 нанокомпозит добијен од поли(γ -глутаминске киселине) из новоизолованог соја bacillus subtilis 17B
(Serbian Chemical Society, 2023)
Poly(γ-glutamic acid) (PGA), naturally produced by Bacillus species, is a biodegradable, non-toxic, biocompatible, and non-immunogenic negatively charged polymer. Due to its properties, it has found various applications ...
Comparison of non-destructive techniques and conventionally used spectrometric techniques for determination of elements in plant samples (coniferous leaves) / Поређење недеструктивних и конвенционално коришћених спектометријских техника за одређивање елемената у биљном материјалу (иглице четинара)
(Journal of the Serbian Chemical Society, 2022)
Conventionally used spectrometric techniques of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma optical emission spectrometry (ICP-MS) usually involve time-consuming sample ...
