We comprehensively studied the complexity of mode action adjuvants by uncoupling parameters contributing to spray process during foliar application agrochemicals. The ethoxylated sorbitan esters Tween 20 and 80 improved efficiency pinoxaden (PXD) in controlling grass-weed species greenhouse experiments aiding retention, having humectant properties, maintaining bioavailability, increasing cuticular penetration PXD. nonethoxylated Span showed minimal effects on droplet hydration, or...
In the genome of completely sequenced mesophilic cyanobacterium Synechocystis sp. PCC 6803 three DnaK proteins are encoded, which share a high degree sequence identity in their N-terminal ATPase region as well adjacent peptide-binding domain. However, typical for proteins, C-termini highly diverse. To study functions more detail, we have analyzed abundance individual cells dnaK expression under various stress conditions. The presented results show that all interact with same GrpE nucleotide...
Soft magnetic Ni78.5Fe21.5, Co91.5Ta4.5Zr4 and Fe52Co28B20 thin films laminated with SiO2, Al2O3, AlN, Ta2O5 dielectric interlayers were deposited on 8” Si wafers using DC, pulsed DC RF cathodes in the industrial, high-throughput Evatec LLS-EVO-II magnetron sputtering system. A typical multilayer consists of a bilayer stack up to 50 periods, alternating (50-100) nm thick layers (2-20) interlayers. We introduced in-plane anisotropy these during by combination linear field, seed layer...
The energy-converting NADH:ubiquinone oxidoreductase, also known as respiratory complex I, couples the transfer of electrons from NADH to ubiquinone with translocation protons across membrane. Electron microscopy revealed two-part structure consisting a peripheral and membrane arm. arm contains all cofactors NADH-binding site, whereas has be involved in proton translocation. Owing this, conformation-linked mechanism for redox-driven is discussed. By means electron microscopy, we show that...
Owing to their large saturation magnetization and low hysteresis loss, soft magnetic layers based on amorphous alloys currently receive great attention for potential gigahertz frequencies applications. In this paper, we studied the structural properties of FeCoB/AlN multilayered thin films with in-plane uniaxial anisotropy Fe-28%Co-20%B (at. %) alloy, deposited 8” Si/200 nm-thermal-SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub>...
Magnetic properties of [Co(0.4 nm)/Pt(0.7 nm)]5 multilayers are tailored by controlling the sputtering voltage during growth cobalt layers a facing target cathode. It is shown that increasing up to 150 V leads an improved crystalline texture and this results in larger magnetic anisotropies together with increased out-of-plane coercive fields. At higher cathode 540 V, however, quality slightly worsens accompanied decrease effective anisotropy. Using sputtering, structure can be controlled...
High-quality epitaxial Pt films are usually grown by molecular beam evaporation (MBE) techniques, where the deposited atoms reach substrate with typical thermal energies. To obtain a good growth, is kept at elevated temperatures ranging between few hundred to thousand degrees. While quality improves higher temperatures, above critical temperature Volmer-Weber growth mode starts and causes rough film morphology. Here, we use new type of facing target cathode (FTC) grow onto Al2O3 (0001)...
The influence of the stoichiometry (Bi,Pb)Sr2(Ca,Y)Cu2Oz on its critical temperature and phase purity was investigated. High yttrium lead contents raise 1212 content to 95%, whereas highest 97 K measured inductively for Bi0.4Pb0.35Sr2Ca0.3Y0.7Cu2.05Oz. transition from normally conducting superconducting state takes place over a broad regime at least 40 K. Different grains within one sample have different cation stoichiometries leading variable properties. Furthermore, we show that ordinary...
Abstract Sintering of magnesium oxide ceramics to high density requires temperatures (1500–1800°C), resulting in coarse-grained microstructures, or additives that promote sintering. An alternative is use a fine-grained MgO starting powder with an impurity level < 1% allows appropriate processing conditions. Here, we report about by slip casting, ceramic green bodies can be sintered closed porosity at 1600°C. X-ray diffraction and scanning electron microscopy combined energy-dispersive...

It is shown that increasing up to 150 V leads an improved crystalline texture and this results in larger magnetic anisotropies out-of-plane coercive fields.
