Transesterification of Sunflower Oil Over Waste Chicken Eggshell-Based Catalyst in a Microreactor: An Optimization Study
(MDPI, 2021)
The statistical experimental design (DoE) and optimization (Response Surface Methodology combined with Box–Behnken design) of sunflower oil transesterification catalyzed by waste chicken eggshell-based catalyst were conducted ...
Immobilized Alcalase on Micron- and Submicron-Sized Alginate Beads as a Potential Biocatalyst for Hydrolysis of Food Proteins
(MDPI, 2021)
Enzymatic hydrolysis of food proteins is convenient method to improve their functional properties and physiological activity. Herein, the successful covalent attachment of alcalase on alginate micron and submicron beads ...
Element Content in Volcano Ash, Soil and River Sediments of the Watershed in the Volcanic Area of South Iceland and Assessment of Their Mobility Potential
(MDPI, 2021)
In this work, we present the results of element content in river sediments and soil of the Rangárvellir river in southern Iceland as well as in the volcano ash from the Eyjafjallajökull eruption in 2010. Severe natural ...
Biotransformation of Perrottetin F by Aspergillus niger: New Bioactive Secondary Metabolites
(Türkiye : ACG Publications, 2021)
Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative ...
The Influence of pH on Electrochemical Behavior of Nicotine- Clay based Electrodes
(Belgrade : International Institute for the Science of Sintering (IISS), 2021)
Montmorillonite based clay was acid activated. Nicotine was adsorbed on untreated
and acid activated clay from its aqueous solution at either pH=6 or pH=9.26 (unadjusted pH
solution). The XRD analysis revealed that the ...
A new species of Leonhardia Reitter, 1901 (Coleoptera, Leiodidae, Leptodirini) from Bosnia and Herzegovina, with a key to species of the genus
(Pensoft Publishers, 2021)
A new leptodirine leiodid beetle species belonging to the genus Leonhardia Reitter, 1901, L. solaki sp. nov., from a pit in Bosnia and Herzegovina (western Balkan Peninsula) is described and diagnosed. Important morphological ...
Hydrogen evolution on reduced graphene oxide-supported PdAu nanoparticles
(MDPI, 2021)
Hydrogen evolution reaction (HER) was investigated on reduced graphene oxide (rGO)-supported Au and PdAu nanoparticles in acid solution. The graphene spread over glassy carbon (rGO/GC) was used as a support for the spontaneous ...
Iodide analogs of arsenoplatins - potential drug candidates for triple negative breast cancers
(MDPI, 2021)
Patients with triple negative breast cancers (TNBCs)—highly aggressive tumors that do not express estrogen, progesterone, and human epidermal growth factor 2 receptors—have limited treatment options. Fewer than 30% of women ...
How aromatic system size affects the sensitivities of highly energetic molecules?
(Royal Society of Chemistry, 2021)
Positive values of electrostatic potentials above the central regions of the molecular surface are strongly related to the high sensitivities of highly energetic molecules. The influence of aromatic system size on the ...
GC-FID-MS Based Metabolomics to Access Plum Brandy Quality
(MDPI, 2021)
Plum brandy (Slivovitz (en); Šljivovica(sr)) is an alcoholic beverage that is increasingly consumed all over the world. Its quality assessment has become of great importance. In our study, the main volatiles and aroma ...
