According to real production situation of an 180 t top and bottom combined blown converter at Anshan Steel, a supersonic jet oxygen lance has been designed to carry out water modeling test, in order to avoid the problem of revising lance position which is caused by subsonic jet oxygen lance. The test was carried out b…
The structure and texture of 2.9 mm hot-rolled plate,0.9 mm cold-rolled sheet and annealed temper-rolled sheet of 0.04C low carbon steel DC03 produced by CSP process have been studied. Results showed that the structure of hot-rolled base plate was ferite matrix + a small amount of pearlite dispersed along grain-bounda…
The models for temperature of hot delivery and charging of 280 mm x 380 mm cast bloom and liquid steel cooling from mold to secondary cooling area and air cooling area have been established and the effect of oxygen and nitrogen content in heavy rail steels U71Mn( % ：0.66-0.76C ,0.15-0.35Si, 1.10-1.40Mn) and U75V (% :…
The Q&P process: heating at 880 ℃ for 15 min-quenching to 150~260 ℃(QT) for 5 min -heating to 300℃ for 10 min and oil cooling of steel 0.24C-1.72Si-2.96Ni has been carried out.Results showed that the Q&P treated steel had complicated structure consisting of lath martensite,retained austenite,twinned martensite and ε-c…
Test results indicated that 14.3 mm HTP line-pipe steel strip(0.056C,1.21Mn,0.07Nb,0.01Ti)had seriols anisotropy, the charpy V-otshimpact energy and delamiratig crack tendency of sample perallelod to rling lirec- ton wls obviously higher han that of samples being45° and vetical o mling diecion at same icmperature.

Steel fluid flow behavior in a CSP mold for 60 mm thin slab casting with nozzle submerged depth 220~310 mm, downward angel of outlet -30°~-60°,casting speed 4.2～6.0 m/min has been studied by 1:1 scale water modeling. At cast speed 4.2～5.0 m/min,for nozzle with double side hole,impact depth of CSP mold fluid flow was 8…
The effect of bending radius(2.5~7.5 mm),tension load(20～80 N)and rolling direction of specimen on reversed bending times of imported cold rolled non-orientation silicon steel sheet has been tested. Results showed that as bending radius R was 5 mm,with increasing tension load from 20 N to 60 N,the reversed bending tim…
We demonstrate that a recently developed coating comprised of silicone nanofilaments can be selectively functionalized to yield well defined superhydrophobic, superhydrophilic, superoleophobic or superoleophilic domains on a single substrate, constituting a simple and versatile toolbox for surface scientists to create…
This critical review covers the application of quantum chemistry to the burgeoning area of the heterogeneous oxidation by Au. We focus on the most established reaction, the oxidation of CO at low temperature. The review begins with an overview of the methods available comparing the treatment of the electron-electron i…

Using a sputtering-deposited titanium substrate, incorporating six equally spaced nanolayers of Ti–W alloy, the volume and composition changes accompanying the formation of porous anodic films on titanium in 0.5 wt % NH 4 F in glycerol are investigated. The findings reveal amorphous films with nanotubes of TiO 2 , con…
The pairing of electrons and holes due to their Coulomb attraction in two parallel, independently gated graphene layers separated by a barrier is considered. At a weak coupling, there exists the BCS-like pair-condensed state. Despite the fact that electrons and holes behave like massless Dirac fermions, the problem of…
During the last years, liposomes (microparticulate phospholipid vesicles) have been used with growing success as pharmaceutical carriers for antineoplastic drugs. Fields of application include lipid-based formulations to enhance the solubility of poorly soluble antitumor drugs, the use of pegylated liposomes for passi…
The gelation ability of a series of chiral bis(urea) gels alternates between even and odd chain length and for the even numbered spacers the rheological characteristics can be tuned by the addition of anions according to the anion binding constant.
Stress corrosion cracking (SCC) studies in stainless steels and nickel alloys reveal that all grades and conditions are susceptible to SCC in high-temperature water, whether deaerated or aerated, high H2 or low, theoretical purity water or buffered/ contaminated, lower temperature or higher. However, the kinetics of S…
A trianionic ligand H3L (2-hydroxy-N-(2-[[(2-hydroxyphenyl)methylene]amino]-2-methylpropyl)benzamide) with an inner N2O2 coordination site and an oxygen atom coming from an amide function not involved in this site yields monoanionic LCu- complexes that react with Ln(hfa)3 x 2H2O (hfa = hexafluoroacetylacetonato ligand…
High-temperature proton conductors are promising as electrolytes for intermediate-temperature solid oxide fuel cells. Among them, BaCeO3-based materials have high proton conductivity but rather poor chemical stability. In contrast, barium zirconates are rather stable, but have poorly reproducible densities and conduct…
We employ electrostatic force microscopy to study the electrostatic environment of graphene sheets prepared with the micromechanical exfoliation technique. We detect the electric dipole of residues left from the adhesive tape during graphene preparation, as well as the dipole of water molecules adsorbed on top of grap…
Density functional theory (DFT) and time-dependent DFT calculations have been employed to model Zn meso-tetraphenylporphyrin (ZnTPP) complexes having different beta-substituents, in order to design an efficient sensitizer for dye-sensitized solar cells. To calculate the excited states of the porphyrin analogues, at le…
Nanoroughness is beneficial for superhydrophobicity and low adhesion. Self assembly of hydrophobic alkanes has been used to modify flat and microstructured surfaces. Various nanostructures, produced by three-dimensional alkane crystals, have been fabricated by changing the crystal density. Microstructures were fabrica…
