Here, a systematic study of magnetite nanoparticle (NP) formation in the presence functional polyphenylenepyridyl dendrons and dendrimers different generations structures (such as focal groups, periphery combination phenylene pyridyl moieties) has been reported. For certain dendron/dendrimer concentrations structures, well-dispersible, multi-core, flower-like crystals are formed which display ferrimagnetic-like behavior. It is noteworthy that least complex second generation with carboxyl...
We report a novel method for development of magnetically recoverable catalysts prepared by thermal decomposition palladium acetylacetonate in the presence iron oxide nanoparticles (NPs). Depending on conditions, reaction results either dispersed mixture Pd and NPs or their aggregates. It was demonstrated that loading, temperature, solvent, NP size composition are crucial to control product including degree aggregation NPs, catalyst properties. The controlled polarization magnetic forces...
The paper presents data on a three-year study (2020-2022) of the effect liquid-phase biological product containing iron nanoparticles (LPB-Fe), obtained by biosynthesis using green tea extract, yield potatoes Skarb variety and activity soil enzymes under conditions Tverskaya areas. Comparative efficiency LPB-Fe, original LPB biopreparation, solution Fe NPs was studied in field against background NPK application. results showed that maximum productivity (669.1 g/bush) foliar treatment...
The influence of the content a hydrophilic Pd(II) compound (disodium tetrachloropalladate, Na2PdCl4) on its adsorption and nanoparticle (NP) formation in pores hydrophobic micro/mesoporous hypercrosslinked polystyrene (HPS) was systematically investigated. morphology composition HPS-Pd nanocomposites were studied using transmission electron microscopy, X-ray fluorescence measurements, liquid nitrogen physisorption. size Pd-containing NP found to depend compound. Catalytic testing these...
The purpose of this work was to study both the separate and combined effects liquid-phase biological (LPB) product Fe 3 O 4 nanoparticles on yield potatoes Skarb variety, as well soil microflora. biosynthesis O4 carried out using green tea extract FeSO ∙7H 2 solution, concentration 0.1 mol/l. effectiveness obtained LPB-Fe studied under field conditions against background NPK fertilizers application. results a three-year experiment (2020–2022) showed that when spraying plants at vegetative...
A promising direction in agriculture is the use of metal nanoparticles as nanofertilizers, which can increase yield agricultural crops and, at same time, minimize frequency fertilization due to long-term release nutrients. One environmentally safest and cheapest methods synthesizing biosynthesis using plant extracts. During redox reaction, proteins, carbohydrates, organic acids, phenols other metabolites are able transfer electrons cations, restoring their charge zero on nanometer scale....
This work sets out to investigate a green-synthesized biopreparation produced by introducing iron or copper nanoparticles into microbial liquid-phase biological product (LBP). The obtained were analyzed diffuse reflectance IR spectroscopy and introduced the LPB at stage of its ripening in LPB:particle solution volume ratio 50:1. As result, two new biopreparations – LPB-Fe LPB-Cu obtained. All samples, as well nanoparticles, underwent laboratory testing on flax seeds Tverskaya variety. Iron...
The article investigates the effect of iron nanoparticles introduced into composition a liquid-phase biological agent (LPB) on germination and biometric parameters, such as average length weight one seedling, fiber flax. Iron were obtained by green synthesis using 0.5 mol/L FeCl3∙6H2O solution precursor tea extract reducing agent. finished LPB in volume ratio 1:50 to obtain LPB-Fe Both agents tested during flax seeds. Two ways studied - seed watering inoculation, while both cases...
