Evaluation of silver-incorporating zeolites as bifunctional electrocatalysts for direct borohydride fuel cells
(Royal Society of Chemistry, 2019)
Three zeolites (A, X and Y) with Ag incorporated in their cages are tested as bifunctional electrocatalysts
for direct borohydride fuel cells (DBFCs). Ag zeolites are characterised by XRD, FTIR, nitrogen sorption
and ...
Tailoring the electrochemical charge storage properties of carbonaceous support by redox properties of heteropoly acids: where does the synergy come from?
(Springer Science and Business Media LLC, 2019)
The synergistic effects between two Keggin-type heteropoly acids (HPAs) and carbon surface were examined and elucidated. An improved high rate capability (and potential high capacitor electrode for supercapacitors) of the ...
Electromagnetic simulation of MXene-based plasmonic metamaterials with enhanced optical absorption
(Springer, 2020)
In this contribution we propose, design and numerically analyze a plasmonic metamaterial for enhanced optical absorption, based on 100 nm thick titanium carbide (Ti3C2Tx) MXene sheets. The analyzed metamaterial is built ...
Semi‑rational design of cellobiose dehydrogenase for increased stability in the presence of peroxide
(Springer International Publishing, 2020)
Cellobiose dehydrogenase (CDH, EC 1.1.99.18) from white rot fungi Phanerochaete chrysosporium can be used for constructing biosensors and biofuel cells, for bleaching cotton in textile industry, and recently, the enzyme ...
Characterization of silicon carbide ceramics obtained from porous carbon structure achieved by plant carbonization
(Elsevier, 2020)
The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) ...
Four Decades of Organic Anthropogenic Pollution: a Compilation for Djerdap Lake Sediments, Serbia
(Springer Science and Business Media LLC, 2019)
Analysis of limnic sediments can serve as a tool to assess sedimentary pollution for both the status quo as well as changes over time. However, in environmental studies, often only a small number of established well-studied ...
Synthesis and preliminary screening for the biological activity of some steroidal Δ4-unsaturated semicarbazone derivatives
(Elsevier, 2019)
Eleven new steroidal mono- and bis(semicarbazones) 2a–e, 4d and 3a–e have been prepared starting from various 3-oxo-α,β-unsaturated steroids. Mono-semicarbazones 2a–e were further subjected to ethyl chloroacetate in boiling ...
Examination of degradation and ecotoxicology of pethoxamid and metazachlor after chlorine dioxide treatment
(Springer Nature Switzerland AG 2020, 2020)
Chlorine dioxide has been reported as very
efficiently removing pesticides and other organic compounds
from water matrixes. Due to pesticide toxicity
and potential toxicity of their degradation products, it is
important ...
Experimental Examination and Thermodynamic Description of the Ternary Bi-Ge-In and -Sn Systems
(Springer Science and Business Media LLC, 2019)
In the present study, ternary Bi-Ge-In and Bi-Ge-Sn systems were experimentally investigated using differential thermal analysis (DTA), scanning electron microscopy with energy dispersive spectroscopy (SEM–EDS) and x-ray ...
Peroxidase-Sensitive Tyramine Carboxymethyl Xylan Hydrogels for Enzyme Encapsulation
(Springer, 2019)
Derivatives of xylans were synthesized from corncob xylan by carboxymethylation, oxidization with different molar ratios of periodate (5, 10 15 and 20 mol%) and by reductive amination with tyramine. Modifications of tyramine ...
