The feasibility of the application Photo-Fenton process in treatment aqueous solution contaminated by Tylosin antibiotic was evaluated. Response Surface Methodology (RSM) based on Central Composite Design (CCD) used to evaluate and optimize effect hydrogen peroxide, ferrous ion concentration initial pH as independent variables total organic carbon (TOC) removal response function. interaction effects optimal parameters were obtained using MODDE software. significance their interactions tested...

High-aspect-ratio titanate nanotubes (NT) and nanowires (NW) were produced by the hydrothermal conversion of TiO2 at 400 K. The morphology was studied high-resolution transmission electron microscopy (HRTEM). formation ordered nanoobjects depended on time conversion. Shorter synthesis times favored hollow nanotube production while during prolonged treatment thermodynamically more stable formed. Titanate decorated Rh nanoparticles. structure stability nanocomposites thermal gravimetric (TG),...
The co-ordination of dimethyltin(IV) to 5′-GMP, 5′-ATP and 5′-d(CGCGCG)2 their sugar constituents (D-ribose 2-deoxy-D-ribose) was investigated in aqueous solution by means potentiometric titration 1H 31P NMR spectroscopic methods. results showed that acidic media the phosphate groups can provide suitable sites for metal ion co-ordination, while hydroxy sugars or moieties two nucleotides play a role this process at higher pH. base 5′-GMP were not co-ordinated dimethyltin(IV). stability...
The role of characteristic phospholipids native membranes, phosphatidylcholine (PC), phosphatidylglycerol (PG), and cardiolipin (CL), was studied in the energetics acceptor quinone side photosynthetic reaction centers Rhodobacter sphaeroides. rates first, kAB(1), second, kAB(2), electron transfer that charge recombination, kBP, free energy levels QA-QB QAQB- states, changes compensating protein relaxation were determined RCs incorporated into artificial lipid bilayer membranes. In embedded...
Green mold of Pleurotus ostreatus, caused by Trichoderma species, has recently resulted in crop losses worldwide. Therefore, there is an emerging need for rapid means diagnosing the causal agents. A PCR assay was developed detection pleurotum and pleuroticola, two pathogens causing green P. ostreatus. Three oligonucleotide primers were designed identifying these species a multiplex based on DNA sequences within fourth fifth introns translation elongation factor 1alpha gene. The detected...
The interaction between single-walled carbon nanotubes and photosynthetic reaction centers purified from purple bacterium Rhodobacter sphaeroides R-26 has been investigated. Atomic force microscopy studies provide evidence that center protein can be attached effectively to the nanotubes. typical diameter of nanotube is 1−4 nm 15 ± 2 without with centers, respectively. Light-induced absorption change measurements indicate stabilization P+(QAQB)- charge pair, which formed after single...
The complex formation of vanadium(IV) with 1,3,5-triamino-1,3,5-trideoxy-cis-inositol (taci) and 1,3,5-trideoxy-1,3,5-tris(dimethylamino)-cis-inositol (tdci) was studied in aqueous solution the solid state. constants [VIVO(taci)]2+, [VIVO(tdci)]2+, [VIV(tdci)2]4+ deprotonation product [VIV(tdci)2H-1]3+ were determined (25 °C, 0.1 M KNO3). Cyclic voltammetry measurements established a reversible one-electron transfer for [VIV(tdci)2H-m](4-m)/[VIII(tdci)2H-n](3-n) couple (0 ≤ n, m 6) strongly...
The purified photosynthetic reaction center protein (RC) from Rhodobacter sphaeroides R-26 purple bacteria was bound to porous silicon microcavities (PSiMc) either through silane-glutaraldehyde (GTA) chemistry or via a noncovalent peptide cross-linker. characteristic resonance mode in the microcavity reflectivity spectrum red shifted by several nanometers upon RC binding, indicating infiltration into (PSi) photonic structure. Flash photolysis experiments confirmed photochemical activity of...
Abstract Low‐temperature thermal chemical vapor deposition (thermal CVD) synthesis of multi‐walled carbon nanotubes (MWCNTs) was studied using a large variety different precursor compounds. Cyclopentene oxide, tetrahydrofuran, methanol, and xylene:methanol mixture as oxygen containing heteroatomic precursors, while xylene acetylene conventional hydrocarbon feedstocks were applied in the experiments. The catalytic activity Co, Fe, Ni, their bi‐ well tri‐metallic combinations tested for...
Abstract Photosynthetic reaction center (RC) is one of the most important proteins, because it Nature's solar battery converting light energy into chemical potential in photosynthetic membrane assuring conditions for carbon reduction cells. Although developed nanometer scale, and working nanoscopic power, this protein that assures input practically whole biosphere on Earth. The extremely large quantum yield primary charge separation (close to 100%) RC offers a big challenge use nanodevices....
