(Elsevier, 2021)
This investigation was aimed to develop films and coatings based on natural biopolymers and active components, with physicochemical and functional properties for application in antimicrobial packaging. Biopolymer films ...
Optimization of microbial fuel cell operation using Danube River sediment
(Elsevier, 2020)
One of the main global focuses of mankind today is the required switch to new energy sources. Generating energy from waste is one of the potential solutions that can be achieved using microbial fuel cells (MFCs). Microorganisms, ...
Analysis and experimental demonstration of forced periodic operation of an adiabatic stirred tank reactor: Simultaneous modulation of inlet concentration and total flow-rate
(Elsevier, 2021)
It is well known, that forced periodic operation possesses the potential for process improvements. Nevertheless, only a small number of applications is reported, due to complex realization, limited predictability and high ...
Novel azo pyridone dyes based on dihydropyrimidinone skeleton: Synthesis, DFT study and anticancer activity
(Elsevier, 2021)
Seven novel azo dyes with 2-pyridone and dihydropyrimidinone moieties have been synthesized and thoroughly characterized. The azo-hydrazone tautomerism has been investigated by experimental and theoretical approaches. ...
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 ...
Littoral eutrophication indicators are more closely related to nearshore land use than to water nutrient concentrations: A critical evaluation of stressor-response relationships
(Elsevier, 2020)
Biological assessmentmetrics and water chemistry measurements are used to quantify the link between stressors
and their effects on lake ecosystems, for the Water Framework Directive. However, correlations between ...
The NaxMnO2 materials prepared by a glycine-nitrate method as advanced cathode materials for aqueous sodium-ion rechargeable batteries
(Elsevier, 2021)
Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies ...
Aluminum-based self-powered hyper-fast miniaturized sensor for breath humidity detection
(Elsevier, 2020)
An aluminum-based, self-powered, miniaturized sensor for breath humidity detection is presented. The sensor is designed as an interdigitated capacitor made out of sputtered aluminum 1 % silicon (Al 1 %Si) thin film, 700 ...
Influence of surface coverage of kaolin with surfactant ions on adsorption of ochratoxin A and zearalenone
(Elsevier, 2021)
A natural kaolin from Serbia was modified with different amounts of octadecyldimethylbenzyl ammonium (ODMBA) - (25, 50 and 90% of kaolin cation exchange capacity). Samples were denoted as OKR-25, OKR-50 and OKR-90. Several ...
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 thelimited durability of Pt-nanoscale materials that operate at high voltages during thecathodic oxygen reduction reaction. In this work, ...
