AB  - Picea omorika essential oil was analyzed by gas chromatography combined with mass
spectrometry (GC/MS). Electrochemical measurements showed that this green inhibitor
reduces the corrosion rate of steel with a significant efficiency of 93% after 4 h at a
concentration of 200 ppm. Polarization measurements showed that the essential oil is a
mixed type inhibitor. The inhibited and non-inhibited surface of the steel was analyzed by
scanning electron microscopy (SEM) and contact angle measurements. X-ray
photoelectron spectroscopy (XPS) provided a deeper insight into the mechanism of
corrosion inhibition. The adsorption of organic active substances on the steel surface
follows the Langmire adsorption isotherm. Experimental studies were completed with the

AB  - While traditional corrosion inhibitors are quite effective at protecting metal, they also pollute the environment.
Since conifers are renewable plants, there has been a lot of interest in using plant extracts as green corrosion
inhibitors [1,2]. They fit industry standards and make excellent raw materials for corrosion inhibitors. However,
because of the high dosage and unclear composition of these corrosion inhibitors, they have not been successfully
used in industry. In this work black pine (Pinus nigra, PN) and Pančić spruce essential oils were synthesized from
fresh needles, which were further tested as a mixture of green organic substances that inhibit steel corrosion. In
addition, the active substances of black pine essential oil (α-pinene, β-pinene, and caryophyllene) were tested
under the same conditions and their effect on the corrosion rate was compared with the effect of black pine
essential oil. The influence of phytochemicals (bornyl-acetate, borneol, and camphene) on the effectiveness of the
essential oil of Pančić's spruce, as well as on the adsorption on steel, was evaluated by theoretical and surface
methods. Through experiments and theoretical calculation, the corrosion inhibition effect of these inhibitors on
steel was studied in 1 M HCl solution at 25 C. The optimal inhibitor concentration as well as the time of immersion
were assessed by Electrochemical impedance spectroscopy.
It has been demonstrated that all inhibitors become more effective over time. At the same concentration of
80 ppm, the most prevalent component of the PN essential oil, α-pinene, demonstrated a poorer corrosion
prevention efficacy than β-caryophyllene, that reached 96% inhibition efficiency. Both PN and Pančić essential oil
were mixed types of inhibitors with prevalent influence on the inhibition of the cathodic reaction, as shown by
polarization measurements. SEM and XPS analysis confirmed the presence of borneol and bornyl-acetate, along
with non-soluble oxides that formed a protective film on metal surface. Binding mechanism of the Pančić essential
oil inhibitor molecules was resolved with the analysis of the projected density of states [3]. The theoretical
calculations [4] indicated that some of the phytochemicals in Pančić essential oil bond to the steel by chemisorption
(bornyl-acetate and borneol) while others by physisorption (camphene). This has also been confirmed by values of
adsorption free energy determined from Langmuir Isotherm.

AB  - Context Benzene and other aromatic groups, as planar groups with π electrons cloud, tend to form stacking interactions which have an important role in various chemical and biological processes. In order to have a better insight in the nature of these interactions, we have performed a fractal analysis on patterns of electron density and electrostatic potential for two benzenes in stacking interaction. The calculated fractal dimension follows the trend of the calculated interaction energy for the interplanar distances of 4.0 to 6.0 Å, which partially coincides with the strongest attractive stacking interactions. The fractal dimension vs. energy dependences were fitted with the logistic curve, and the fitting coefficient was 0.96 up to 1.00. Methods For the benzene stacking interaction energy, with a range of conformations and distances between two benzenes, DFT calculations at the B3LYP+D3/aug-cc-pVDZ level were performed with the TURBOMOLE software. The fractal analysis for electron density and electrostatic potential has been done by python scripting.

AB  - Stabilization of G-quadruplexes formed in the promoter regions of oncogenes with small molecules is recognized as a convenient method to control oncogenes’ overexpression in cancer cells. Due to a huge number of potential G-quadruplex structures in DNA, the success of this method is critically dependent on ligand–quadruplex selectivity. Although external π–π stacking of the ligand to the top G-quartet was extensively exploited in the design of new ligands with aromatic cores, it is believed that symmetric porphyrin derivatives are not capable of specifically interacting with flanking nucleotides. Here, we show that TPyP4, an analogue of TMPyP4, exhibits more pronounced selectivity toward the overhang. To this end, we examined the binding of TMPyP4, TPyP4, TPyAP4, TBP, and TMABP4 to the c-MYC promoter Pu24I G-quadruplex via density functional theory calculations and molecular dynamics based on the classical force field. The ranking of ligand binding energies in the end-stacking binding mode, TMABP4 > TMPyP4 ≈ TPyAP4 > TPyP4≈ TBP, was mainly governed by van der Waals interactions in the binding pocket. TPyP4 was also found to intercalate between the A3 and G2 bases of the overhang and simultaneously stack on two guanine bases of the top G-quartet. The binding affinity for intercalation was stronger than for end-stacking. We propose that the metalation of TPyP4 with a cation whose favored coordination geometry is octahedral might stabilize intercalation over an end-stacking binding mode to a greater extent.

AB  - In this work, a tetrafunctional epoxy resin entitled 2,3,4,5-tetraglycidyloxy pentanal (TGP) was tested and investigated as a potential corrosion inhibitor for mild steel (MS) in 0.5 M H2SO4 solution. The corrosion inhibition process for mild steel was employed alongside various techniques, such as potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), temperature effect (TE), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and theoretical approaches (DFT, MC, RDF and MD). Further, the corrosion efficacies obtained at the optimum concentration (10−3 M of the TGP) were 85.5% (EIS) and 88.6% (PDP), respectively. The PDP results indicated that the TGP tetrafunctional epoxy resin acted the same as an anodic inhibitor type in 0.5 M H2SO4 solution. SEM and EDS analyses found that the protective layer formed on the MS electrode surface in the presence of TGP could prevent the attack of the sulfur ions. The DFT calculation provided more information regarding the reactivity, geometric properties and the active centers of the corrosion inhibitory efficiency of the tested epoxy resin. RDF, MC and MD simulations showed that the investigated inhibitory resin have a maximum inhibition efficiency in 0.5 M H2SO4 solution.

AB  - Green eco-friendly inhibitors have become very popular due to their remarkable properties
such as biodegradability, environmental acceptability, safety, availability, and
renewability. Amino acids (ACs) are one of them, as constituents of vital importance for
all living beings. Several AC systems were examined in this study as steel inhibitors in 1
M HCl solution: three ACs separately, glycine, glutamic acid and cysteine; their mixture,
as well as their dipeptide (glycine and glutamic acid) and tripeptide glutathione (glycine,
glutamic acid and cysteine). Their inhibition efficiency was evaluated and compared by
electrochemical methods. The steel surface with adsorbed inhibitor was analyzed by

svojstava: biorazgradivost, netoksičnost, dostupnost i obnovljivost. U njih spadaju i
amonokiseline (AK), kao sastojci od vitalnog značaja za sva živa bića. U radu je ispitan
inhibitorski efekat nekoliko AK na čeliku u 1 M HCl: tri samostalne AK, glicin,
glutaminska kiselina i cistein; smeša ove tri AK, kao i njihov dipeptid (glicin i glutaminska
kiselina) i tripeptid glutation (glicin, glutaminska kiselina i cistein). Inhibitorska efikasnot
AK je određena elektrohemijskim merenjima. Meren je ugao kvašenja površine čelika sa
adsorbovanim inhibitorom, energija veza inhibitora i supstrata je određivana XPS
metodom, a topografija AFM. Razlike u vezivanju inhibitora za supstrat su analizirane
teorijskim proračunima., Green eco-friendly inhibitors have become very popular due to their remarkable properties
such as biodegradability, environmental acceptability, safety, availability, and
renewability. Amino acids (ACs) are one of them, as constituents of vital importance for
all living beings. Several AC systems were examined in this study as steel inhibitors in 1
M HCl solution: three ACs separately, glycine, glutamic acid and cysteine; their mixture,
as well as their dipeptide (glycine and glutamic acid) and tripeptide glutathione (glycine,
glutamic acid and cysteine). Their inhibition efficiency was evaluated and compared by
electrochemical methods. The steel surface with adsorbed inhibitor was analyzed by
contact angle measurements, AFM and XPS. The intrinsic differences in adsorption
between these green inhibitors were analyzed by theoretical calculations.",

AB  - New era heteroatom-doped carbons, relying on different biomass residues, play a rising role in contemporary carbon energy storage technology. Herein, an abundant waste of viticulture industry – vine shoots (VS) was carbonized and examined as electrode material for supercapacitors with non-conventional aqueous electrolyte. Biochar obtained by pre-carbonization treatment of vine shoots (at 300 °C) is impregnated with ZnCl2 at 600 °C (ACvs600) and 700 °C (ACvs700), to synthesize carbon with developed specific surface area, close to 1500 m2 g−1. The high specific capacitance of ACvs is achieved in Al-based electrolyte, which allows working voltage of 1.8 V ACvs700/Al2(SO4)3/ACvs700 cell delivers the energy density of 24 Wh kg−1 at 1 A g−1, which is higher than one measured in typical Na2SO4 (∼16 Wh kg−1) and H2SO4 electrolyte (∼11 Wh kg−1). By using Trasatti&Dunn surface charge distribution models, the reallocation of inner vs. outer charge in Al-based electrolyte is found to be different from that in H2SO4 electrolyte. The nature of the interaction between pristine/defective graphene and hydrated Al3+ ion is examined by Density Functional Theory (DFT) and discussed. Gathered experimental and theoretical data open novel perspectives for using carbon in more sustainable energy storage devices.

AB  - The planarity and the appropriate size of the porphyrin ring make porphyrin derivatives ideal ligands for stacking to guanine quartets and they could thus be used as anti-cancer drugs. In this contribution we analyzed complexes of a guanine quartet with a porphyrin molecule, magnesium porphyrin and calcium porphyrin. As magnesium and calcium ions are located in the center and above the porphyrin ring, respectively, the two metalloporphyrins are expected to have different impacts on the target. The optimized structures of the three systems revealed geometrical changes in the guanine quartet upon complexation: while stacking of porphyrin and magnesium porphyrin does not induce significant changes, calcium porphyrin considerably distorts the quartet's structure, which has significant implications for the binding properties among guanine molecules. Ab initio molecular dynamics simulations revealed that the systems perform small fluctuations around the equilibrium structures. The largest atom displacements are performed by the calcium ion. The interacting quantum atoms methodology enabled analysis of the binding properties in the studied complexes. Interestingly, although the proximity of the calcium ion is responsible for the quartet's pronounced deformation and weakening of guanine-guanine binding, it also enables stronger binding of the metal ion to the quartet, resulting in a more stable complex. These results imply that metalloporphyrin-like ligands with out-of-plane central ions might represent promising drug candidates in anti-tumor treatment.

AB  - The diiron benzenedithiolato carbonyl complex is a biomimetic catalyst for proton reduction whose catalytic pathways depend on the solvent properties and the proton donor acidity. Previous studies showed that the initial steps in electrocatalytic generation of dihydrogen in acetonitrile involve a two-electron reduction followed by protonation, but the structures and physical properties of other intermediates are not known. We have performed a systematic quantum chemical analysis of the reduced and protonated complexes with benzenedithiolato and benzenediselenato ligands that can be formed by addition of up to three electrons and/or protons. The exchange of the sulfur atoms by selenium increases the basicity of the iron atoms but is not favorable for the protonation of the chalcogen atoms. Our results show that the most stable singly protonated complexes possess the proton in a bridging position between both irons, irrespective of the total complex charge. The second proton can be attached to a chalcogen atom or to an iron atom in a terminal position, depending on the complex charge. The most stable isomers of the triply protonated complexes have protons in the bridging and terminal positions as well as one proton bound to a chalcogen atom. Standard reduction potentials and acidities of all examined complexes were computed. We also discussed possible intermediates and reaction pathways in the electrocatalytic proton reduction to molecular hydrogen formation.

AB  - Guanine self-assemblies are promising supramolecular
platforms for optoelectronic applications. The study (Hua et al., J. Phys. Chem. C 2012, 116, 14,682−14,689) reported that alkaline cations cannot modulate the electronic absorption spectrum of G-quadruplexes, although a cation effect is observable
during electronic relaxation due to different mobility of Na+ and K+ cations. In this work, we theoretically examined whether divalent Mg2+ and Ca2+ cations and hydration might shift excited charge-transfer states of a cation-templated stacked G-quartet to the absorption red tail. Our results showed that earth alkaline cations
blue-shifted nπ* states and stabilized charge-transfer ππ* states relative to those of complexes with alkaline cations, although the number of charge-separation states was not significantly modified. Earth alkaline cations were not able to considerably increase the
amount of charge-transfer states below the Lb excitonic states. Hydration shifted charge-transfer states of the Na+-coordinated Goctet to the absorption red tail, although this part of the spectrum was still dominated by monomer-like excitations. We found Goctet electron detachment states at low excitation energies in aqueous solution. These states were distributed over a broad range of excitation energies and could be responsible for oxidative damage observed upon UV irradiation of biological G-quadruplexes.

AB  - Rising demands for renewable energy sources have led to the development of dye sensitized solar cells. It
is a challenge to find a good and low cost sensitizer, which has a low environmental impact. In this work,
we conducted spectroscopic and electrochemical experiments, as well as quantum-chemical calculations of the natural pigment hypericin, in order to provide insight into its sensitizing efficiency. To this
end, three identical cells were made and characterized. Although this pigment exhibited good adsorption
onto a semiconductor surface, a high molar absorption coefficient (43 700 L mol−1 cm−1
) and favorable
alignment of energy levels and provided a long lifetime of electrons (17.8 ms) in the TiO2 photoanode, it
was found that the efficiency of hypericin-sensitized solar cells was very low, only 0.0245%. We suggest
that this inefficiency originated from a low injection of electrons into the conduction band of TiO2.
This conclusion is supported by the density functional theory calculations which revealed a low electron
density in the anchoring groups of electronically excited hypericin. The results of this work could be valuable not only in the photovoltaic aspect, but also for application of hypericin in medicine in photodynamic
therapy

AB  - Understanding the basic chemistry between highly reactive free radicals and dopamine is an important step in characterizing the antioxidative activity of catecholamine neurotransmitters. In this work, we simulated the reactions between dopamine and hydroxyl, peroxyl and methoxy radicals in aqueous solution by employing first principle molecular dynamics based on density functional theory and the BLYP functional. The simulations provide mechanistic insight into the reaction mechanisms but underestimate reaction timescales. The failure of the BLYP functional to address the formal hydrogen atom transfer barriers between dopamine and free radicals is attributed to the self-interaction error.

AB  - The dynamic aspect of solvation plays a crucial role in determining properties of strong intramolecular hydrogen bonds since solvent fluctuations modify instantaneous hydrogen‐bonded proton transfer barriers. Previous studies pointed out that solvent‐solute interactions in the first solvation shell govern the position of the proton but the ability of the electric field due to other solvent molecules to localize the proton remains an important issue. In this work, we examine the structure of the O−H⋅⋅⋅O intramolecular hydrogen bond of dibenzoylmethane in methanol solution by employing density functional theory‐based molecular dynamics and quantum chemical calculations. Our computations showed that homogeneous electric fields with intensities corresponding to those found in polar solvents are able to considerably alter the proton transfer barrier height in the gas phase. In methanol solution, the proton position is correlated with the difference in electrostatic potentials on the oxygen atoms of dibenzoylmethane even when dibenzoylmethane‐methanol hydrogen bonding is lacking. On a timescale of our simulation, the hydrogen bonding and solvent electrostatics tend to localize the proton on different oxygen atoms. These findings provide an insight into the importance of the solvent electric field on the structure of a strong intramolecular hydrogen bond

AB  - In this work, we study G-octet-metal ion complexes which act as models for the G-quadruplex supramolecular arrangement within DNA. We used DFT based molecular dynamics (BLYP-D3/DZVP+PW+GTH) for configuration sampling purposes and calculated electronic excitations to initially populated (Franck-Condon) states. To capture charge transfer content of the excited states, we used descriptors who rely on the analysis of the one-electron transition density matrix acquired from the TDDFT calculation (CAM-B3LYP/6-31G(d)).
