Synthesis, characterization and electrochemical properties of iron doped phosphate tungsten heteropoly acid (Fe-PWA) and it’s bronze (Fe-PWB): Comparative study
(Association for ETRAN Society, 2023)
In this work, synthesized 12-tungstenphosphoric acid (H3PW12O40 × nH2O; PWA) was further ionically exchanged with Fe3+ ions, which led to the formation of the 12-tungstophosporic acid iron salt, (FePW12O40 × nH2O; Fe-PWA). ...
Rare-Earth/Manganese Oxide-Based Composites Materials for Electrochemical Oxygen Reduction Reaction
(MDPI AG, 2022)
The main objective of this research was a systematic development of advanced micro/nanostructured materials based on the most used metal-oxides for ORR and metal-oxides with an extremely low-loading of Pt for comparison. ...
Dripping Rainfall Simulators for Soil Research - Performance Review
(MDPI, 2023)
Rainfall simulators represent often-used equipment for soil research. Depending on their performance, they could be appropriate for some soil research or not. The aim of this research is to provide insight into the ...
Immunomodulatory Effects Mediated by Nano Amorphous Calcium Phosphate/Chitosan Oligosaccharide Lactate Coatings Decorated with Selenium on Titanium Implants
(Basel, Switzerland : MDPI, 2023)
The aim of this work is in situ anodization/anaphoretic deposition of a nano amorphous calcium phosphate (ACP)/chitosan oligosaccharide lactate (ChOL) multifunctional hybrid coating decorated with selenium (Se) on a titanium ...
Correlating Structure and KA2 Catalytic Activity of Zn(II) Hydrazone Complexes
(Wiley, 2023)
Two new Zn(II) complexes bearing tridentate hydrazone-based ligands with NNO or NNS donor atoms were synthesised and characterised by elemental analysis, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopies, ...
COVID infection in 4 steps: Thermodynamic considerations reveal how viral mucosal diffusion, target receptor affinity and furin cleavage act in concert to drive the nature and degree of infection in human COVID-19 disease
(Elsevier, 2023)
We have developed a mechanistic model of SARS-CoV-2 and SARS-CoV infection, exploring the relationship between the viral diffusion in the mucosa and viral affinity for the angiotensin converting enzyme 2 (ACE2) target. ...
Copper(II) and silver(I) complexes with dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz): the influence of the metal ion on the antimicrobial potential of the complex
(Royal Society of Chemistry (RSC), 2023)
Dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz) was used as a ligand for the synthesis of new copper(II) and silver(I) complexes, [CuCl2(py-2pz)]2 (1), [Cu(CF3SO3)(H2O)(py-2pz)2]CF3SO3·2H2O (2), [Ag(py-2pz)2]PF6 ...
Oxide Powder Mixture with Poly-vinyl Alcohol (PVA) and added Polyethylene Glycol (PEG) as Plasticizer
(Belgrade : Association for ETRAN Society, 2023)
Powder mixture consisted of ZnO, Mn2O3 (MnCO3) and Fe2O3 blended powders, was found laminating during compaction. Polyvinyl alcohol (PVA) and a combination of PVA with polyethylene glycol (PEG) added as a plasticizer, were ...
Iron salt-promoted oxidation of steroidal phenols by m -chloroperbenzoic acid: a route to possible antitumor agents
(Royal Society of Chemistry, 2022)
Iron salt-promoted reaction of estrone and its derivatives with meta -chloroperoxybenzoic acid was developed and epoxyquinols were further transformed. Most compounds showed in vitro ...
White-rot fungal pretreatment of wheat straw: effect on enzymatic hydrolysis of carbohydrate polymers
(Institutul de Chimie Macromoleculara Petru Poni, 2023)
The aim of the study was the comparative analysis of degradation of wheat straw lignin by white-rot fungi and its implications on the efficiency of enzymatic hydrolysis of holocellulose. Peroxidases were found to be ...
