Varietal differences of Prokupac, Evita and Čokot Zemun based on their anthocyanins content in grape skin extract
(Chemistry & Biodiversity, 2021)
In this study we have analyzed the anthocyanin composition of skin extracts of three red grape varieties Prokupac, Evita and Čokot Zemun in order to distinguish these cultivars based on their anthocyanin profile. Also, ...
Controlling Pd-Catalyzed N-Arylation and Dimroth Rearrangement in the Synthesis of N,1-Diaryl-1H-tetrazol-5-amines
(American Chemical Society (ACS), 2021)
The Pd-catalyzed N-arylation method for the synthesis of eighteen N,1-diaryl-1H-tetrazol-5-amine derivatives is reported. By running the reactions at 35 °C, compounds were isolated as single isomers since the undesired ...
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 ...
Dynamic stability of active sites in hydr(oxy)oxides for the oxygen evolution reaction
(Springer Science and Business Media LLC, 2020)
The poor activity and stability of electrode materials for the oxygen evolution reaction (OER) are the main bottlenecks in the water splitting reaction for H2 production. Here, by studying activity
stability trends for ...
Eliminating dissolution of platinum-based electrocatalysts at the atomic scale
(Nature Publishing Group, 2020)
A remaining challenge for deployment of proton-exchange membrane fuel cells is the
limited durability of Pt-nanoscale materials that operate at high voltages during the
cathodic oxygen reduction reaction. In this work, ...
Ionic diffusion in iPP: DC electrical conductivity
(Elsevier, 2020)
This study provides a new insight into the relationships between absorption and adsorption processes that occur during the treatment of iPP in aqueous solutions of metal-chloride salts, as well as the impact of these ...
Ideal efficiency of resonant cavity-enhanced perovskite solar cells
(Springer Science and Business Media LLC, 2020)
Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost ...
Chemo- and biocatalytic esterification of marchantin A and cytotoxic activity of ester derivatives
(Elsevier, 2020)
Chemical and biocatalytic synthesis of seven previously undescribed marchantin A ester derivatives has been presented. Chemical synthesis afforded three peresterified bisbibenzyl products (TE1-TE3), while enzymatic method, ...
Anti-human albumin monoclonal antibody immobilized on EDC-NHS functionalized carboxylic graphene/AuNPs composite as promising electrochemical HSA immunosensor
(Elsevier, 2020)
Diagnosis and treatment of some important diseased and metabolic disorders is based on successful detection of albumin. In this work, we aim to develop a simple immunosensor for the detection of human serum albumin in ...
Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
(Elsevier, 2020)
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A ...
