Purpose This paper sets out to study the corrosion of No. 20 carbon steel without film and with films of different qualities in high‐temperature boiler water with different Cl − concentrations. Design/methodology/approach The static simulated experiment in high‐pressure autoclave and the surface analysis methods of EP…
Polarized Raman scattering measurements have been performed on ${\mathrm{Na}}_{0.5}\mathrm{Co}{\mathrm{O}}_{2}$ single crystal from $8\phantom{\rule{0.3em}{0ex}}\text{to}\phantom{\rule{0.3em}{0ex}}305\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Both the ${A}_{1g}$ and ${E}_{1g}$ phonon modes show a softening below ${T}_{c1…
A constitutive model, based on an ( n +1)-phase mixture of the Mori–Tanaka average theory, has been developed for stress-induced martensitic transformation and reorientation in single crystalline shape memory alloys. Volume fractions of different martensite lattice correspondence variants are chosen as internal variab…
A selective, sensitive and rapid liquid chromatography-tandem mass spectrometry method has been developed for the determination of caudatin-2,6-dideoxy-3-O-methy-beta-d-cymaropyranoside (CDMC) in rat plasma. This method involves a plasma clean-up step using liquid-liquid extraction, followed by LC separation and posit…
Si, Ge, and Ti substituted nanotubes have been theoretically investigated. We employed a mixed approach for the computation of the electronic structure of these systems under periodic conditions. Band energy methods were then employed at a pseudopotential and all-electron schemes. The optimized geometries, binding, an…
Abstract A new organic–organic salt, 2‐aminopyridinium‐4‐hydroxybenzenosulfonate, has been synthesised and characterised by means of FT‐IR and FT‐Raman spectroscopies, differential scanning calorimetry (DSC) and single crystal X‐ray crystallography. Its vibrational spectra have been discussed on the basis of quantum c…
Metal–ligand interactions can be used to create coordination polymer multilayers (see picture). Growth is linear with layer and bilayer number, and the bilayer thickness depends on deposition concentration. This approach combines the stability of covalent multilayers with the responsiveness of polyelectrolyte-based mu…
Abstract The substrate‐dependent surface‐enhanced Raman scattering (SERS) of 4‐aminobenzenethiol (4‐ABT) adsorbed on Au surfaces has been investigated. 4‐ABT is one of the very unique adsorbate molecules whose SERS spectral patterns are known to be noticeably dependent on the relative contribution of chemical enhancem…
Pure poly(lactide-co-glycolide) and polystyrene surfaces are not very suitable to support cell adhesion/spreading owing to their hydrophobic nature and low surface energy. The interior surfaces of large porous 3D scaffolds were modified and activated using radio-frequency, low-pressure air plasma. An increase in the w…
Abstract Terpolymers have been prepared by the condensation of 2,4‐dihydroxyacetophenone (2,4‐HA) and dithiooxamide (D) with formaldehyde (F) in the presence of hydrochloric acid as catalyst with varying the molar proportions of the reactant. Compositions of the terpolymer have been determined by elemental analysis. T…
Abstract In the present study, the effect of deposition pressure on the deposition rate and various properties of diamond‐like carbon (DLC) coatings were investigated. The DLC coatings were deposited on Si substrates using a bipolar‐type plasma‐based ion implantation and deposition plasma based ion implantation and de…
Understanding the structure, folding, and stability of collagen is complex because of its length and variations in the amino acid (AA) sequence composition. It is well known that the basic constituent of the collagen helix is the triplet repeating sequence of the form Gly-X(AA)-Y(AA). On the basis of previous models a…
Cr-doped SiC thin films have been fabricated on Al 2 O 3 and Si substrates by using dual ion beam sputtering deposition at room temperature. The films have been characterized by x-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy and x-ray photoelectron spectroscopy…
We discuss numerical algorithms for the determination of periodic surface structures from light diffraction patterns. With decreasing details of lithography masks, increasing demands on metrology techniques arise. Scatterometry as a non-imaging indirect optical method is applied to simple periodic line structures in o…
Abstract Terpolymers (2,4‐DHPBF) were synthesized by the condensation of 2,4‐dihydro‐xypropiophenone, biuret, and formaldehyde in the presence of acid catalyst with varying the molar ratio of reacting monomers. Terpolymer composition has been determined on the basis of their elemental analysis and their number–average…
This Letter studies the relationship between the elastic constants and the microstructure of nanocrystalline diamond thin films deposited by the chemical vapor deposition method doping various concentration of N2 gas. The elastic constants were measured by resonant ultrasound spectroscopy and picosecond laser ultrasou…
The PyrR protein regulates expression of pyrimidine biosynthetic (pyr) genes in many bacteria. PyrR binds to specific sites in the 5' leader RNA of target operons and favors attenuation of transcription. Filter binding and gel mobility assays were used to characterize the binding of PyrR from Bacillus caldolyticus to…
Polycrystalline Bi 3.15 Nd 0.85 Ti 3 O 12 (BNT) thin films were fabricated on Pt/Ti/SiO 2 /Si by the sol–gel method. The dependence of precursor solution concentration (PSC) on the grain orientation of the films was observed, and a model was proposed to explain it by taking into account the effect of bulk nucleation.…
Carbothermal reduction–nitridation (CRN) of SiO 2 –Al 2 O 3 –CaO powders was performed under various firing conditions to investigate the formation process of Ca‐α sialon hollow balls composed of nanosized particles. Scanning electron microscopy and transmission electron microscopy observations of the samples obtained…
Purpose Silicone and polyester resins have been prepared at various compositions with the purpose of determining the best performing binder system. The coating materials that have been developed have been analysed and evaluated for their protection ability. Design/methodology/approach Silicone and polyester resins hav…
