The possibility of synthesizing BaTiO 3 ferroelectric powders of different dispersities by the exchange reactions in molten salts is demonstrated. The proposed method has some advantages, such as the possibility of preparing titanate materials of different dispersities and the simplicity and controllability of the che…
Increasing deep-water oil and gas recovery has highlighted the need for high integrity, high fatigue performance girth welds in steel catenary riser systems. Such systems include girth welds made from one side. However, the widely used fatigue design classification, UK Class F2, for such welds is not well founded, but…
Woven and knitted polyester fabrics were pretreated with formulations containing waterborne UV curable resins and silica particles to improve inkjet print quality. The selected formulations were applied with low add-on to reduce the adverse effect on fabric hand without sacrificing the print quality. A print pattern w…
The dimension of the final stage of cold forging a product is different from that of the die. The difference is influenced by various effects such as elastic deformation of the die and elastic recovery of the billet. In this study, in order to investigate the trend of elastic expansion of the die and elastic recovery…
The processes for producing methanol from syngas and syngas from natural gas are simulated. A kinetic model for the reaction of steam-carbon dioxide reforming of methane that is in good agreement with the experimental data obtained for the ranges of gas hourly gas velocities of 1000 to 10000 h −1 , temperatures of 700…
We demonstrate the growth of crystalline Li 4 C 60 films. The low-energy electron diffraction pattern of the films indicates the formation of polymer chains in the plane of the surface, consistent with the reported crystal structure. Electron energy loss and photoemission spectra identify the Li 4 C 60 polymer as a lo…
The migration behavior of C60 on Ni(111) has been inferred from its growth morphology at various substrate temperatures, as observed with scanning tunneling microscopy. The number density of islands increased and their average sizes decreased anomalously in the temperature range of approximately 573 K to approximately…
Supercapacitors can provide the transient power that the cranking need in low temperature. Aiming to reduce the volume of lead acid battery and the cost of the power system, supercapacitor and lead acid battery hybrid systems are investigated as power sources for diesel engine cold starting by using cold starting test…
Cavitation erosion is predominant in pipelines for liquid transportation, causing damage to pipe wall, impeller and their accessories. The present study is focused on development of cavitation -wear resistant nano-ceramic particle-reinforced polymer matrix material; and on study of its feasibility to be used as lining…
Structure and properties of MgB 2 -based materials in the form of cylinders, rings, quadratic and rectangular blocks manufactured using high-pressure (2 GPa), hot-pressing (30 MPa), hot isostatic pressing (0.1 GPa), and atmospheric pressure (with predensification by broaching) from different types of B and MgB 2 are c…
We have reproduced the model system containing A2-rhodopsin, NR-PE, A2-PE, and ATR-dimer-PE in order to study photosensitized damage of rhodopsin within photoreceptor membranes of rod outer segments. We have demonstrated that irradiation of such a system with visible light (400-700 nm) distorts the most important func…
A novel poly(azomethine) (PAM) thin film deposited by vapor deposition polymerization (VDP) process was used in the emissive layer of polymer light-emitting diodes (PLEDs). 1,4-Bis(4-formylstyryl)benzene (BFSB) and 4,4''-diamino-(1,1',4',1'')-terphenyl (DAT) were co-deposited to form PAM thin films at various substrat…
Biphasic tricalcium phosphate (BTCP) powders composed of α-tricalcium phosphate (α-TCP) and β-tricalcium phosphate (β-TCP) were prepared using amorphous calcium phosphate (ACP) precursor after heat treatment at 800oC. The in vitro dissolution behavior of the powders was examined after soaked in 0.1M NaAc-HAc buffer so…
In the case of welded structures with cracks, a number of parameters, such as those with units of length, makes it difficult to present the results of numerical solutions in a form convenient for direct engineering applications, such as flaw assessment procedures. For centre-cracked components under tension, it is sho…
Density d temperature dependences of Ga-Bi melts with 0, 10.2, 16.2, 29.8, 42.0, 51.6, 61.5, 80.0 and 100 at.%Bi were measured using absolute gamma-absorption technique with accuracy of 0.2 to 1.5 % (depending on bismuth concentration). In addition, temperature dependences of ultrasound velocity D s were determined fo…
The control of wall loads in fusion devices, in particular with respect to the life time limitations of wall components due to material erosion and migration, will be decisive for the realisation of a fusion power plant operating in steady state, while in a pulsed experiment like ITER the primary goal for plasma-wall…
A novel reference signal generator is proposed for active power filters. The method takes advantage of a computationally efficient Recursive DFT and it is based on extraction of the positive sequence component from the measured current with the Fortescue decomposition. The extraction of the positive sequence component…
ABSTRACT The purpose of the present work was to study the influence of cut (manual and using a sharp knife) and packaging film (bioriented polypropylene and polyolefin PD‐961) on the sensory quality of fresh‐cut butterhead lettuce stored under passive modified atmosphere at 5C. Results showed that lettuce cut by hand…
The X-80 steel chemistry has been modified by increased Mn, Cr and Mo that decrease BS, and two groups of leaner base chemistries have been used with low carbon (LC) and high carbon (HC) that correspond to 0·04 and 0·07 wt-%C respectively. The alloy design approach is to lower BS and to provide offsetting decreases to…
The preparation and performance of hypoxanthine (Hx) electrochemical biosensor, which was based on iron (III) meso‐tetraphenylporphyrin (FeTPP) nanoparticles (NPs), is reported in this work. FeTPP NPs prepared by mixing solvent techniques with diameters ca. 25~45 nm and were used as a mediator. The XOD/FeTPPNP/GC elec…
