Metabolomics study of Populus type propolis
(Elsevier, 2017)
Herein, we propose rapid and simple spectroscopic methods to determine the chemical composition of propolis derived from various Populus species using a metabolomics approach. In order to correlate variability in Populus ...
Persistent organic pollutants (POPs) in sediments from river and artificial lakes in Serbia
(Elsevier, 2017)
In an attempt to evaluate the toxicological condition of the most important river and artificial lakes in Serbia, 52 grab-samples were collected from different locations. Sediment samples were analyzed for PCBs (PCB 28, ...
Montmorillonite/poly(urethane-siloxane) nanocomposites: Morphological, thermal, mechanical and surface properties
(Elsevier, 2017)
The aim of this work was to prepare and characterize the series of segmented polyurethane nanocomposites (PUNC) modified with poly(dimethylsiloxane) and based on montmorillonite (Mt) as a nano-filler. alpha,omega-Dihydro ...
in/out Isomerism of cyclophanes: a theoretical account of 2,6,15-trithia-[3(4,10)][7]metacyclophane and [3(4,10)][7]metacyclophane as well as their halogen substituted analogues
(Royal Soc Chemistry, Cambridge, 2017)
A detailed theoretical investigation of cyclophanes with a divergent set of methods ranging from molecular mechanics through semiempirical to ab initio is presented. Cyclophanes have attracted interest over the years due ...
Comparative Analysis of Phenolic Compounds in Seven Hypericum Species and Their Antioxidant Properties
(Natural Product Incorporation, 2017)
A comparative analysis of the phenolic compounds in the 70% EtOH extracts of Hypericum acutum, H. androsaemum, H. barbatum, H hirsutum, H maculatum, and H richeri has been carried out using high-performance liquid ...
Optimization of the extraction process of polyphenols from Thymus serpyllum L. herb using maceration, heat- and ultrasound-assisted techniques
(Elsevier, 2017)
Despite the fact that Thymus serpyllum is well-known medicinal plant and its chemical profile and biological activity have been investigated, there is no detailed study regarding the influence of different techniques and ...
Occurrence of synthetic musk compounds in surface, underground, waste and processed water samples in Belgrade , Serbia
(Springer, New York, 2017)
This study assessed the state of waters in Belgrade regarding pollution with musk compounds as the target contaminants. Eleven of these compounds were alicyclic, two were macrocyclic, and one was polycyclic. Solid-phase ...
Study of potential harmful elements (arsenic, mercury and selenium) in surface sediments from Serbian rivers and artificial lakes
(Elsevier, 2017)
This investigation examines surface sediment samples from rivers and artificial lakes (Serbia) to quantify levels of potentially harmful elements (As, Hg, and Se) and several ancillary elements (Al, Fe, Mn, Ca, Mg, C, H, ...
Preliminary investigation on the use of the Q-switched Nd:YAG laser to clean corrosion products on museum embroidered textiles with metallic yarns
(Journal of Cultural Heritage, 2017)
The classic methods of cleaning oldfashioned textile museum objects with metallic threads often do not yield the expected results. The use of laser in the conservation of these objects plays an important role as very ...
Chemical secretion and morpho-histology of the pygidial glands in two Palaearctic predatory ground beetle species: Carabus (Tomocarabus) convexus and C. (Procrustes) coriaceus (Coleoptera: Carabidae)
(Taylor & Francis Ltd, Abingdon, 2017)
Although all ground beetles have pygidial glands homologous in structure and function, there are many differences among species, often significant, in terms of chemical composition of the secretion and morphology of the ...
