Methodological approaches in heritological valorization of old patents
(Београд : Друштво за етичност и вредновање у култури и науци и Централни институт за конзервацију, 2020)
Within the protection of industrial heritage, patents and other works of intellectual
technological heritage are assessed heritologically and technologically. The results of valorization
show that the heritological value ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier, 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticles (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Antistaphylococcal and biofilm inhibitory activities of Frangula alnus bark ethyl-acetate extract
(Elsevier, 2020)
Staphylococcus aureus is one of the leading causative of numerous infections that is resistant to various antibiotics. Since that we are facing with a serious problem of bacterial resistance it is necessary to find a new ...
Synthesis, X-ray structures and magnetic properties of Ni(II) complexes of heteroaromatic hydrazone
(Elsevier, 2020)
Two binuclear double end-on azido bridged Ni(II) complexes, [Ni2L2(μ-1,1-N3)2(N3)2]⋅2H2O (1a), and [Ni2L2(μ-1,1-N3)2(N3)2]⋅4H2O (1b) having the same inner sphere, where L=((E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(thiazol-2-yl) ...
The NaxMnO2 materials prepared by a glycine-nitrate method as advanced cathode materials for aqueous sodium-ion rechargeable batteries
(Elsevier, 2021)
Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies ...
Biofilms in caves: easy method for the assessment of dominant phototrophic groups/taxa in situ
(Springer Science and Business Media LLC, 2020)
Domination of certain aerophytic phototrophic group or specific taxon in biofilms is connected with biofilm features recognised in situ. Well-developed, gelatinous, olive to dark-green biofilms are composed mostly of coccoid ...
New Theoretical Insight into Fluorination and Fluorine–Fluorine Interactions as a Driving Force in Crystal Structures
(American Chemical Society (ACS), 2020)
Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F···F interactions is followed by the shift of the ...
Bisaurones-enzymatic production and biological evaluation
(Royal Society of Chemistry, 2020)
The Trametes versicolor laccase catalyzed oxidation of chalcone butein afforded four dimers of aurone sulfuretin (i.e. two regioisomeric pairs of diasteromers, 1-4) as the major products. The formation of the dimers was ...
Overview of Erasmus+ NETCHEM project: ICT networking for overcoming technical and social barriers in instrumental analytical chemistry education
(Springer Science and Business Media LLC, 2020)
The paper briefly presents goals, activities, challenges, and outcomes of the NETCHEM project (http://www.netchem.ac.rs/) that was co-funded by the Erasmus+ Program of European Union (573885-EPP-1-2016-1-RS-EPPKA2- CBHE-JP). ...
Genetic and morphological variation in Chara contraria and a taxon morphologically resembling Chara connivens
(Taylor & Francis, 2020)
Charophyte species delineation is regularly based on a set of thallus morphological character- istics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. ...
