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 ...
Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Elsevier, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using α,ω-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
Modulating Excited Charge-Transfer States of G‑Quartet Self- Assemblies by Earth Alkaline Cations and Hydration
(American Chemical Society (ACS), 2020)
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 ...
Thienochromene derivatives inhibit pSTAT1 and pSTAT5 signaling induced by cytokines
(Elsevier, 2020)
Furanocoumarins, particularly furo[3,2-c]coumarins, are found in many natural products. However, coumarins
annulated to a thiophene ring have received scarce attention to date in the literature. Therefore, we synthesize ...
Examples of Wide Microwave Bandpass Microstrip Filters on Felt Substrate
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Application of one type of wide bandpass filter on felt (textile) substrate is introduced. Copper tape and conductive textile are used for metallization (conductive layer). It is an initial work. The patterns were done in ...
Multidisciplinary research method for designing and selection of bio-inspired profiles in the conceptual designing stage
(Springer Nature Switzerland AG 2020, 2021)
A multidisciplinary research method was employed with the intention to create a series of bio-inspired flattened airfoils, observe their aerodynamic characteristics, and analyse their applicability to small devices or to ...
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 ...
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. ...
Graph theory applied to microelectronics intergranular relations
(Taylor & Francis Group, 2021)
The focus of this study is on the control of layers between grains by applying graph theory. We performed modification of BaTiO3 nanoparticles with Y2O3. The results of capacitance change on submicron level are the part ...
