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, ...
Potencijal poljoprivredne biomase u sistemima proizvodnje biogasa u Republici Srbiji / Potential of agricultural biomass in biogas production systems in the Republic of Serbia
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
Biomasa predstavlja prema zvaničnim podacima najznačajniji potencijal obnovljivih izvora energije u Republici Srbiji. Ona čini oko 63% od ukupnog potencijala, ali za sada njena iskorišćenost nije na zadovoljavajućem nivou. ...
Corrosion behaviour of AA2024 aluminium alloy in different tempers in NaCl solution and with the CeCl3 corrosion inhibitor
(Wiley - VCH Verlag GmbH & Co, 2020)
The paper analyses the corrosion behaviour of naturally and artificially aged
AA2024 alloy in NaCl solution and in the presence of an environment ‐ friendly
corrosion inhibitor, CeCl 3 . On the basis of the values of ...
What is the preferred geometry of sulfur–disulfide interactions?
(Royal Society of Chemistry, 2020)
Non-covalent interactions between disulfide fragments and sulfur atoms were studied in crystal structures of small molecules and by quantum chemical calculations. Statistical analysis of the geometrical data from the ...
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 ...
Improvement of d–d interactions in density functional tight binding for transition metal ions with a ligand field model: assessment of a DFTB3+ U model on nickel coordination compounds
(Royal Society of Chemistry (RSC), 2020)
To improve the description of interactions among the localized d, f electrons in transition metals, we have introduced a ligand-field motivated contribution into the Density Functional Tight Binding (DFTB) model. Referred ...
Influence of inhibitors on the corrosion behavior of the X5CrNi18 10 stainless steel ‐ welded joint
(Wiley‐VCH GmbH, 2020)
This study considers the corrosion behavior of the X5CrNi18 10 stainless steel‐welded joint in NaCl solution, with and without the presence of several corrosion inhibitors (NaNO3 , Ce(NO3)3, and CeCl3). The degree of ...
Diversity and seasonal dynamics of culturable airborne fungi in a cultural heritage conservation facility
(Elsevier, 2021)
An extensive aeromycological survey was performed in the premises of a cultural heritage conservation facility to estimate fungal propagule concentrations in both indoor and outdoor air and seasonal dynamics with regard ...
Food Allergy & Food Allergens
(Elsevier, 2021)
Food carries risks. Food allergies are risk that comes from certain food proteins (food allergens). These are natural constituents of food that can provokes life threatening conditions in significant part of population. ...
NMR-based metabolomics for frauds detection and quality control of oregano samples
(Elsevier, 2021)
In this work 1H NMR metabolomics has been employed for quality control of oregano samples. NMR data and morphological analysis (MA) were combined by PCA, obtaining a model able to individuate non-marketable samples, and ...
