Introduction: In the present study, we hypothesized that a novelapproach to promote vascularization would be to create injectablethree dimensional (3-D) scaffolds within growth factor that enhancethe sustained release of growth factor and induce the angiogenesis.Material and Methods: We demonstrate that a 3-D scaffold…
Effect of Nb addition on mechanical properties and shape memory behavior of Ti–Mo–Ga alloys was investigated by cyclic loading-unloading tensile tests, tensile tests at various temperatures and Vickers hardness tests. The martensitic transformation start temperature (Ms) decreased by 20 K with 1 at% increase of Nb con…

The first observation of a spin polarized excited state of a paramagnetic metal-complex using time-resolved electron paramagnetic resonance (TREPR) spectroscopy is reported for octaethylporphinatooxovanadium(iv). The TREPR spectra show well resolved orientation dependent hyperfine splitting to the I = 7/2 vanadium nuc…
Potential, pH, and their gradients are important parameters in determining the electrochemical reactivity of metals in crevices. Although an voltage alone can be responsible for the activation of crevice corrosion that occurs immediately, changes in pH may be necessary for crevice corrosion to occur in the delayed for…

A long-term fertilizer experiment, over 10 years, studied the effect of NPK fertilizers alone and in combination with green manuring (Sesbania aculeata) or farmyard manure (FYM) on potassium (K) balance and release properties in rice-wheat cropping sequence on Aquic Natrustalfs. The treatments consisted of control, 10…

During the process of quickly producing pathologic sections of the living tissues with ultrasonic sonoporation, it has been found that the exciting ultrasonic signal has an evident effect on the pathologic section. For the sake of understanding the effect and obtaining the best state of quickly producing pathologic se…
This article has introduces the basic components and characteristics of a femoto-second electron diffraction system, i.e. the photo-cathode, magnetic lens, deflector and detector with doubled MCP etc., and demonstrated our design method and results. The photo-cathode is an Ag film deposition on a sapphire disk and the…
The interaction of molecules (HCl, NH 3 and H 2 O) and the hydrogenterminated diamond (001) surface is studied with ab inito simulation. Both the energy and the geometry indicate that the surface H atoms are more favourable to pull the H atoms of these polar molecules. The calculated charge redistribution reveals that…
The radiation-induced changes taking place in poly(vinylidene fluoride) (PVDF) films exposed to electron beam irradiation were investigated in correlation with the applied doses. Films were irradiated in air at the melting temperature (174 o C) using a universal electron beam accelerator at doses in the range 50 200 k…
A loop antenna using a left-handed transmission line is proposed. The antenna has a one wavelength circumference and gives an omnidirectional pattern in the plane of the loop, whilst working in an eta = 0 mode. In contrast, a conventional right-handed loop with the same dimensions has a figure of eight pattern in the…
The glycolytic enzyme phosphoglycerate enolase (PGE) catalyses the step from 2-phosphoglycerate to phosphoenolpyruvate in glycolysis. A control analysis of PGE on growth, glycolytic flux and product formation in Lactococcus lactis subsp. lactis IL1403 is presented. A library of strains with a modulated expression of P…
Nanostructures in the form of thin films, nanoparticles, nanoporous materials, nanocomposites, and bulk nanocrystalline materials are of interest both for basic scientific research and technological applications as their properties are dominated by the extremely large specific surface areas. Such surfaces have general…
Integration of polymer self assembly with semiconductor processing enables sub-lithographic patterning of integrated circuit (IC) device elements and offers a non-traditional pathway to performance improvements (Black, 2005). We discuss target applications including surface-roughening for on-chip decoupling capacitors…
Single-walled boron nanotubes (BNTs), which has been synthesized successfully recently, were imagined as duals (hexagonal pyramidal structures) of carbon nanotubes (CNTs) in the literature. In this work, we call attention to the fact that BNTs are not limited to hexagonal pyramidal structures constructed from the so-c…
The main challenge in designing diagnostic devices able to move along the colon is their locomotion method. Manipulating friction with the colonic surface is a key requirement for their safe and atraumatic propagation. One possible solution is to generate friction by means of adhesive forces. For this reason, a diagno…
This work aimed to study the corrosion inhibition of carbon steel in 2 M HCl solutions using some aminopyrimidine derivatives. In this investigation the techniques of measurements were: weight loss, linear polarization, impedance and corrosion penetration. The inhibitory effect of the investigated compounds resulted f…
Effective control of cathode airflow in a direct fired solid oxide fuel cell gas turbine (SOFC/GT) hybrid power system is critical to thermal management of a fuel cell stack. Hybrid fuel cell turbine designs often incorporate the use of a valved hot air bypass in parallel with the cathode flow to divert a portion of t…
