A new method of protein nucleation and crystallization based on Langmuir-Blodgett technology is here utilized for the template stimulation of crystal growth of so far non-crystallized proteins. Microcrystals (60-120 microm) of bovine cytochrome P450scc and human protein kinase CKII alpha subunit were obtained with use…
The influence of salt deposits on the atmospheric corrosion of zinc was studied in the laboratory. Four chloride-containing salts, NaCl, NH 4 Cl , ZnCl 2 , and MgCl 2 , and four sulfate-containing salts, Na 2 SO 4 , ( NH 4 ) 2 SO 4 , ZnSO 4 , and MgSO 4 , were investigated. The salts were applied by spraying a saturat…
Nitrogen-doped hydrogenated amorphous carbon, a C : H : N x films, were synthesized by microwave electron cyclotron resonance plasma-enhanced chemical vapor deposition, using N 2 / C 2 H 2 as precursors. Such films, with thickness in the range of a few tens of nanometers, very smooth, and pinhole free, appear as ele…
Abstract Multi-walled as well as single-walled carbon nanotubes are conveniently prepared by the pyrolysis of organometallic precursors, such as metallocenes and phthalocyanines, in a reducing atmosphere. Pyrolysis of organometallics alone or in mixture with hydrocarbons also yields aligned nanotube bundles with usefu…
Due to their unique expected properties thermoelectric microdevices, thermogenerators as well as Peltier coolers, are of high demand for different applications namely for telecommunication purposes. Thus worldwide efforts are undertaken to expand the technology for thermoelectric devices into the field of typical micr…
The aqueous polymerization of 3-hydroxyaniline (3HA) was studied using sodium dichromate as oxidant in presence of hydrochloric acid. The effect of hydrochloric acid, sodium dichromate and monomer concentration on the polymerization rate, specific viscosity of the obtained polymer and a.c.conductivity was investigated…
The CODATA Data Science Journal is a peer-reviewed, open access, electronic journal, publishing papers on the management, dissemination, use and reuse of research data and databases across all research domains, including science, technology, the humanities and the arts. The scope of the journal includes desc…
During the reaction injecting molding process of polyurethane−urea (PUU) based on 4,4‘-methylenebisphenyl diisocyanate (MDI), urethane as well as urea linkages are produced when a highly fluorescent aromatic diamine is used as a chain extender. To explore intrinsic fluorescence as a cure characterization technique, mo…
Photothermal deflection spectroscopy has been applied to optical absorption measurements in As2S3, Se, and As–S glasses. The spectroscopic method is demonstrated to be suitable for evaluation of small absorption in thin samples, while its accuracy is affected by light scattering. For As2S3, as-evaporated films give hi…
Poly[3-(3,4-difluorophenyl)thiophene], MPFPT, electrochemically deposited onto carbon paper, was studied in electrochemical capacitors utilizing several tetraalkylammonium/acetonitrile electrolyte systems. Although the surface morphology of the polymer varied with the anion used for polymerization, an open and porous…
Composite materials containing thin Shape Memory Alloy (SMA) wires show great promise as materials able to adapt their shape, thermal behaviour or vibrational properties during service. Tools for designing such materials are however far from being available. The work presented here reports the main achievements of a c…
It is well established that the second-phase particle (SPP) size distribution and the cladding chemical composition affects the in-reactor corrosion rate of boiling water reactor (BWR) cladding, although the mechanisms are not yet fully understood. To further study these effects, the corrosion and hydriding performanc…
Composite electrodes based on mixed valence oxide nanoparticles (Ox) embedded in an electrically conductive polymer (ECP) were investigated toward the oxygen reduction reaction (ORR). ECP was polypyrrole (PPy), and Ox was the spinel mixed valence oxide Cu 1.4 Mn 1.6 O 4 , which is known to be an electrocatalyst of the…
The deformation behavior near room temperature in Zn-22 mass%Al alloy including nanocrystalline structure produced with Thermo Mechanical Controlling Process (TMCP) technology has been characterized over a wide range of strain rates from 10−6 to 10−1 s−1 at temperatures from 273 to 473 K . The microstructure of TMCP p…
Subtilisin is produced as a precursor that requires its N-terminal propeptide to chaperone the folding of its protease domain. Once folded, subtilisin adopts a remarkably stable conformation, which has been attributed to a high affinity Ca(2+) binding site. We investigated the role of the metal ligand in the maturatio…
Two heterothiometallic cluster compounds [MOS3Cu3(4-pic)6]·0.5[M2O7] (M = Mo 1, W 2) having a cationic cluster skeleton and a polyoxometalate cluster anion, as well as two other clusters [MOS3Cu3(4-pic)6]·[BF4] (M = Mo 3, W 4) have been synthesized for nonlinear optics studies. Single-crystal X-ray diffraction data sh…
Several cyclam incorporating silica gels have been synthesised using three different methods, including a sol–gel approach. These various materials show different textures and the macrocycle contents can reach values up to 1.5 mmol g−1. Cu(II) and Co(II) complexes of these modified silica gels have been studied. Final…
The intercalation of a cationic azobenzene derivative into the interlayer space of magadiite was conducted by the ion exchange reactions between magadiite and p-[2-(2-hydroxyethyldimethylammonio)ethoxy]azobenzene bromide. X-Ray diffraction and elemental analysis confirmed the formation of the p-[2-(2-hydroxyethyldimet…
Chromium dioxide films on TiO 2 (110) single crystals have been grown by using chemical vapor deposition. The average growth rate was ∼1.8 nm·min - 1 . Powder X-ray diffraction indicated that the films were highly (110) textured. X-ray photoelectron spectroscopy showed that the CrO 2 films were continuous and no other…
