A highly conserved histidine-rich region with unknown function was recognized in the large subunit of [NiFe] hydrogenases. The HxHxxHxxHxH sequence occurs most membrane-bound hydrogenases, but only two these histidines are present cytoplasmic ones. Site-directed mutagenesis His-rich T. roseopersicina membrane-attached Hyn hydrogenase disclosed that enzyme activity significantly affected by replacement His104 residue. Computational analysis hydrogen bond network subunits indicated second...
A simplified, fast, and effective production method has been developed for the synthesis of manganese ferrite (MnFe2O4) magnetic nanoparticles (MNPs). In addition to wide applicability MnFe2O4 MNPs, this work also reports their application in DNA isolation first time. An ultrasonic-cavitation-assisted combustion was applied MNPs at different furnace temperatures (573 K, 623 673 773 K) optimize particles' properties. It shown that synthesized 573 K consist a spinel phase only with adequate...
The presence of microorganisms and inorganic pollutants in water bodies results adverse effects on nature as well human health. In this study, clay-based adsorbents were used for the removal phosphates Escherichia coli bacteria. Two samples, Na-Zr-50-2.5 Na-Zr-50-5, prepared using 2.5 5 mmol zirconium per gram clay. former material has shown better Langmuir phosphate adsorption capacity (∼11.5 mg P/g) at pH 4. Chitosan modification was applied to improve its performance higher pH. Post...
Development and application of hybrid membranes containing multi-component materials are increasing day by in the fields environmental protection water treatment. In this research, efficiency titania nanowire (TiO2 NW)-based self-supported was investigated removal Escherichia coli (E. coli) bacteria MS2 bacteriophages from contaminated mimicking microorganism suspension. Furthermore, toxicology tests on as-prepared were also performed. TiO2 NWs coated with iron(III) oxide (Fe2O3) copper(II)...
The novel photoactive membranes have grabbed the attention in field of environmental protection by employing wastewater treatments and removal microorganisms or organic pollutants from wastewater. Here we present a promising self-supported hybrid membrane for future antimicrobial water treatment applications. In this study, efficiency bacterial cellulose (BC) - zinc oxide (ZnO) multi walled carbon nanotube (MWCNT) adsorption photocatalytic degradation methylene blue (MB) under UV radiation...
Sonochemistry in combination with a combustion procedure was used to prepare superparamagnetic iron oxide nanoparticles. Two different precursors, ferrocene and iron(II)-acetate were dispersed polyethylene-glycol (PEG) molecular weight (200–1000) by using high efficiency ultrasonic technique. The sonochemical treatment initiated the precipitation of iron-hydroxide particles, then PEG based colloids burnt create Three phases observed samples, magnetite (Fe3O4), hematite (α-Fe2O3), maghemite...
In the present study, a new method for synthesis of open-cell soft polyurethane foam (PUF) is developed.Silver nanoparticles are synthesized on surface ultrafine grain (100-500 nm) natural zeolite particles and this than placed as filler in polyurethane.The Ag content PUF about 5 wt%, 1500 ppm, respectively.Most partially or fully covered cell wall which favorable long-term storage.However, soon comes into contact with water human sweat, montmorillonite swells breaking through...
NSO-HETs, 1,4-dioxane, oxane, phenol and morpholine can penetrate biomembranes alter their structure, resulting in an easier permeation of additional molecules.
A sudden increase in polyurethane (PU) production necessitates viable recycling methods for the waste generated. PU is one of most important plastic materials with a wide range applications; however, stability urethane linkage major issue chemical recycling. In this work, termination reactions model molecule, namely methyl N-phenyl carbamate (MPCate), are investigated using G3MP2B3 composite quantum method. Our main goal was to gain insights into energetic profile bond and find an applicable...

In this article, we describe the antimicrobial properties of a new composite based on anodic aluminium oxide (AAO) membranes containing propyl-copper-phosphonate units arranged at predetermined density inside AAO channels. The samples were prepared with four concentrations copper ions and tested as drug different strains Escherichia coli (K12, R2, R3 R4). For comparison, same three types antibiotics using minimal inhibitory concentration (MIC) minimum bactericidal (MBC) tests. Moreover, DNA...
For pathogens identification, the PCR test is a widely used method, which requires isolation of nucleic acids from different samples. This extraction can be based on principle magnetic separation. In our work, amine-functionalized magnesium ferrite nanoparticles were synthesized for this application by coprecipitation ethanolamine in ethylene glycol Mg(II) and Fe(II) precursors. The conventional synthesis method involves reaction time 12 h (MgFe2O4-H&R MNP); however, modified could...
