AB  - HgTe is a II-VI compound semi-metal with inverted band ordering, low effective mass and high electron mobility [1]. Nanostructures based on this compound are intensively studied due to their specific topological properties [2]. In HgTe based nanostructures an inversion in the band ordering is accompanied by a quantum phase transition from a normal insulator to the phase of a nontrivial twodimensional (2D) topological insulator or the Quantum Spin Hall insulator [3]. A good dynamic stability of HgTe monolayer is predicted from first-principles methods [4], which opened the possibility to use this material in thin-layer electronic devices. Even before these theoretical findings, HgTe nanoribbons have been experimentally realized [5], and a topological field effect quantum transistor was proposed [6]. We investigate the electronic and transport properties of low-buckled 2D HgTe zig-zag and armchair nanoribbons. Modeling of electronic states was performed by using a single-particle tight-binding model in the nearest-neighbour approximation [7]. The sp3d 5 s * basis set in the Slater-Koster notation was used. The spin-orbit interaction was included in the model by using the Chadi formalism [8]. We found specific edge states in the range of energies that define the fundamental band gap of 2D HgTe monolayer. Moreover, we show that the electronic and transport properties of these states depend strongly on nanoribbon width and type of edge, and we demonstrate how external fields can be employed to control them.

AB  - Taking into account that powder paprika is among spices that are often subjected to adulteration, the aim of this work was the analysis of twelve different branded powder paprika collected from Serbian markets. The total content of ash and sand was determined, and results have shown that values ranged from 5.40 to 7.80% and from 0.77 to 2.23%, respectively. The inductively coupled plasma optical emission spectrometry method was used for the quantification of 16 elements (Cd, Fe, Ni, Pb, Be, Zn, Cu, Mo, Ti, Sr, Ca, Al, B, Cr, Mg and Mn). Among all determined elements, the most abundant was Ca, followed by Mg and Fe. UV spectroscopy was used as a screening method to determine the adulteration level with Sudan I dye of spice paprika powders. It was found that none of the investigated samples contain Sudan I dye. Furthermore, multivariate classifications models were created for discrimination based on adulterant and powder paprika content in sample mixtures.
