The storage and retrieval of a single-photon polarization q-bit by means of STIRAP through the atoms with degenerate levels is studied theoretically for arbitrary polarization of the driving laser field and arbitrary values of the angular momenta of resonant atomic levels. The dependence of the probability of long-ter…
Ceramic coil springs are one of the most widely used components in mechanical systems under harsh chemical conditions and high temperatures. In real applications of ceramic coil springs, knowing the effect of sintering temperature on their microstructure and strength distribution plays a crucial role. In this paper, t…
Abstract Commercially available TiO2 and BaSO4 nanoparticles were incorporated in polyamide 6 (PA 6) via twin screw extrusion. The primary particle size of nanoparticles was 15 nm and 20 nm. The compounds were manufactured via multiple extrusion and dilution processing steps. The dispersion of the nanoparticles in the…
Abstract We have investigated the crystallization and morphological behaviors of poly(ε‐caprolactone)‐b‐poly(L‐lactide) (PCL‐b‐PLLA) in its autophobic dewetted ultrathin films (∼11 nm) using atomic force microscopy (AFM) and transmission electron microscopy (TEM). The autophobic dewetting process creates a well define…
The blue title compound, long assumed to be an olefin complex on the basis of an apparently single unresolved CN stretching band in the IR spectrum, has been identified by experiment and through DFT analysis as a σ complex with the tungsten atom coordinated to one of the nitrile N centers. The previously reported data…

Solvation forces are crucial determinants in the equilibrium between the folded and unfolded state of proteins. Particularly interesting are the solvent forces of denaturing solvent mixtures on folded and misfolded states of proteins involved in neurodegeneration. The C-terminal globular domain of the ovine prion prot…
The structural and magnetic phase transitions and magnetoresistance of the diluted magnetic semiconductors Cd1 − x Mn x GeAs2 and Cd1 − x Mn x GeP2 have been studied at high hydrostatic pressures, up to 7 GPa. The normal and anomalous Hall coefficients of the samples have been determined graphically from experimental…
Abstract We have shown that it is possible to graft a vinyl monomer from a plasma polymer surface in the presence of UV light without the use of a photoinitiator. A polyethylene glycol methacrylate (PEGMA) coating can be grown from the surface of a methanol plasma polymer via photopolymerization. It is proposed that t…
We have studied the effect of calcination temperature on the phase composition and pore structure of Cu- and Mn-containing supported oxide catalysts. These characteristics have been shown to influence the catalytic activity of the materials for the oxidation of divalent iron in water.
Abstract A new strategy of morphology control was applied for mesoporous silica SBA‐15 to fabricate efficient environment protector, and the micro‐ and macro‐morphology of SBA‐15 were simultaneously controlled in weak acidic condition by using citric acid. Through simply tuning the synthetic temperature, monolithic SB…
Corrosion of one type or another occurs in almost every environment and high performance corrosion protection methods are often too expensive to be economically viable. This work examines the performance of protective layers of Inconel 617, laser clad in the form of salvaged machining chips, to protect a corrosive sub…
The purpose of the investigations was to develop technological conditions of robotized GMA surfacing of experimental protective modules of armours. On the grounds of ballistic tests, the high resistance of armour protective modules against the impact of B-32 armour-piercing incendiaries of 7.62 × 54 mm Mosin rifle car…
A polymeric membrane‐based tin selective electrode was developed by using salicylaldehyde thiosemicarbazone (STSC). The best performance was recorded with a membrane composition of PVC : TBP : ionophore : NaTPB as 28 : 59 : 8 : 5 (w/w%). The Nernstian slope calculated from the calibration curve for Sn 2+ sensor was 28…
Abstract The solvothermal reaction of MnCl2·4H2O or CoCl2·6H2O with tris(4‐carboxyphenyl)‐phosphine oxide (H3TPO), in DMF orDMA resulted in the four coordination polymers [M3(tpo)2(dmf)(H2O)2](1: M = Mn; 2: M = Co), (NMe2H2)[Mn3Cl(HCO2)(htpo)(tpo)(H2O)] (3) and (NMe2H2)[Mn3(tpo)2(OAc)] (4). Structural characterization…
To elucidate the structure of the network of the water retention mechanism of fish-meat gel, the microscopic relationship between the water content and viscoelasticity was investigated, and the specific surface area (S) where the water molecules are adsorbed was also measured. The gel structures of fish-meat, actomyos…
Tyramine β-monooxygenase (TβM), the insect homologue of dopamine β-monooxygenase, is a neuroregulatory enzyme that catalyzes the β-hydroxylation of tyramine to yield octopamine. Mutation of the methionine (Met) ligand to Cu(M) of TβM, Met471Cys, yielded a form of TβM that is catalytically active but susceptible to ina…
Poly(o-phenylenediamine) (POPD) hollow microspheres with Ag submicrometre particles decorated on both inner and outer surfaces of shells as Ag/POPD hollow hybrids have been successfully fabricated through the reduction of AgNO3 by ascorbic acid in aqueous solution containing POPD hollow microspheres. Poly(o-phenylened…
Amorphous nanostructured MnO 2 was anodically deposited onto duplex stainless steel substrate. The cyclic stability of MnO 2 was investigated by chronopotentiometry in 1 M Na 2 SO 4 at two different temperatures. Results demonstrated that the specific capacitance was enhanced significantly after 2000 cycles at 70°C, f…
In this letter, we demonstrate the relationship between the incident angles and the polarization states of transmitted beams on the basis of a kind of helical metamaterials. Through finite-difference time-domain simulations, it is found that the polarization states of the transmitted lights can be tuned by changing th…
