The effect of silver nanparticles on the bactericidal and fungicidal properties natural polymers – cellulose collagen derivatives was investigated. It found that treatment films in a solution leads to change structure: ordering compaction microfibres. is shown new materials, having fairly high different types microorganism, are non-toxic risk-free humans environment.
Chromatographic techniques for determination of biologically active phenols and polyphenols are considered. Various methods sample preparation detection compared. The advantages high performance liquid chromatography with spectrophotometric antioxidants demonstrated. Data on published in the period from 1995 to 2005 analysed.
Abstract A comparison of various presentation forms retention parameters measured in multi‐step gradient elution regimes reversed phase HPLC indicates that indices the scale n‐alkyl phenyl ketones (so‐called Smith′s RI system) have maximal reproducibility. However, determination these for most hydrophilic compounds eluted before first reference acetophenone (RI=800) implies their calculation by extrapolation, can lead to high irreproducibility results, especially with initial isocratic...
In this paper, the results of adsorption and catalytic properties mono- bimetallic palladium rhodium nanoparticles (0.7–6.5 nm) impregnated on γ-Al2O3 were presented. Metal obtained in reverse micelles by two reduction methods: radiation-chemical chemical ions. Three types Rhcore/Pdshell, Pdcore/Rhshell substitution alloy Rh-Pd obtained. The isotope exchange H2+D2⇄2HD conversion ortho-H2⇄para-H2 reactions used as model processes. It was found that with increasing ω=[H2O]/[surfactant]...
Using the radiation–chemical simulation method of free radical reactions with 2,2-diphenyl-1-picrylhydrazyl, we were able to show high antiradical activity water–ethanol extracts from Murraya paniculata. This will allow for creation new bioactive antioxidants based on them. The formation silver nanoparticles (Ag-NP) was determined using silver-ion reduction process by M. paniculata extracts. A band electronic plasmon resonance identified in optical absorption spectra hydrosols Ag-NP dried...
Radiation chemical modeling of redox reactions biologically active compounds from plant materials showed that coumarins possess strong antiradical properties. Data confirming the radioprotective properties these were obtained. Antioxidant activity has been shown for specific medicinal extracts—Melilotus officinalis and Ledum palustre cormus. The radiation transformations revealed an unsubstituted coumarin greater activity.
Electron beam (EB) radiation technologies have been employed to increase efficiency of biologically active nanochips developed for agricultural plants seed pre-treatment with purpose enhancing crop yield and productivity. Iron-containing nanoparticles (NPs), synthesized in reverse micelles following known radiation-chemical technique, served as a multifunctional phytosanitary substance the chips. Porous chip carriers activation has performed by EB ionization (doze 20kGy) carbons (AC)...
