Large area defect of intra-oral or extra-oral mucosa caused by mucosa lesions need suitable graft materials for repair.Tissue engineering methods can provide effective pathway to resolve this problem.Furthermore,full thickness mucosa equivalent constructed by tissue engineering methods also can be used as a model to e…
One of the key contents in tissue engineering trachea replacement research is the scaffold selection.This review summarizes the latest original literatures and investigations about electrospun technique as well as recent progress.To discuss the advantages and disadvantages of natural,synthetic and combined electrospun…
The anharmonic lattice dynamics of rock-salt thermoelectric compounds SnTe and PbTe are investigated with inelastic neutron scattering (INS) and first-principles calculations. The experiments show that, surprisingly, although SnTe is closer to the ferroelectric instability, phonon spectra in PbTe exhibit a more anharm…
运用密度泛函理论(DFT)的杂化密度泛函B3LYP方法,在6-31G*基组水平上对(SiC)n(n=1~5)团簇各种可能的构型进行了几何结构优化,预测了各团簇的最稳定结构.并对最稳定结构的振动特性、成键特性、电荷特性等进行了理论研究.结果表明:(SiC)n团簇形成碳原子骨架,而硅原子生长在碳原子骨架上;在Si和C相互作用形成团簇的过程中,Si原子向C原子有电荷转移,团簇中原子间相互作用呈现共价型;SiC、(SiC)5团簇有相对较高的动力学稳定性;团簇稳定结构的IR最强振动主要是C-Si键的伸缩振动,Raman较强振动均来自C-C键的伸缩振动.
The main object of this article is to study the subclasses of multivalent meromorphic functions by using a linear operator in punctured unit disk. Some geometric properties like coefficients bound, distortion theorems and convolutions property are investigated.
방사성동위원소는 각각의 원소 별로 고유의 반감기를 지 니며 특정 에너지 범위의 방사선을 방출한다[9, 12].이때 방 출되는 방사선의 물리적인 에너지에 의하여 세포가 파괴될 수
Using the different adsorption properties of ssDNA and dsDNA to GO, this study used a real time and efficient fluorescence assay to detect the enzymatic activity of the Klenow fragment with the adsorbed DNA to GO. Results showed that adsorption of fluorescein-tagged ssDNA to GO resulted in fluorescence quenching and D…
Using density functional calculations, we demonstrate that the spin-orbit coupling (SOC) of the Ir4+ ion plays an essential role in determining the antiferromagnetism of the hexagonal spin-chain system Sr3MIrO6 (M = Ni, Co) by tuning the crystal-field level sequence and altering the Ir-M inter-orbital interactions. Th…
Permagnetic oxidation of pyridine-4-carboxaldehyde has been investigated at 25°C using spectrophotometer under acidic condition. The effect of variation of substrate, oxidant and H2SO4 was studied under pseudo first order reaction conditions.
In this study, cotton fabric was coated with intumescent formulations containing different supporting inorganic additives (aluminium trihydrate, zinc borate and zeolite) alongwith kaolin nanoclay using K-control coater. The thermal study of fabric samples was studied using thermogravimetric and differential scanning c…
Nanoparticles are found to be useful as carrier for gene delivery. In the present study, the most biocompatible-Gold nanoparticles were used for carrying serine protease. i.e. Trypsin. It is sensitive to the protease inhibitors present inside the cells and these proteases on binding with gold nanoparticle, loses its s…
The purpose of this study was to investigate the effect of the weight fraction of coir fiber at 5 %, 15 %, 25 %, 35 % and 45 % of the strength of oil-polyester biocomposites shock. Examining cross-section of the test results in order to provide an analysis of the reasons for recommending the feasibility of coir fiber…
The polyurethane ionomers were synthesized at two temperature range using PEG, different diisocyanate [Tolylene diisocyanate (TDI), 1,6-diisocyanatohexane (HMDI), Isophorone diisocyanate (IPDI), 4,4’-methyl bis(cyclohexyl isocyanates) (H12MDI), 4,4’-methyl bis(phenyl isocyanates) (MDI)] and dihydroxy benzoic acid. All…
The possible interrelation between the value of electrode potential φs, surface condition and mechanisms of pore formation of Si was substantiated. The influence of finishing chemical treatment method on the φs of Si-plates was investigated.Features of φs behavior over time in media with different pH values after trea…
Silicon supersaturated with sulfur by ion implantation and pulsed laser melting exhibits broadband optical absorption of photons with energies less than silicon's band gap. However, this metastable, hyperdoped material loses its ability to absorb sub-band gap light after subsequent thermal treatment. We explore this d…
Microstructural and mechanical properties of Ni-YSZ fabricated using SPS processing have been investigated at various sintering temperatures. Our study shows samples to be applied as a SOFC anode have the proper porosity of 40% and high hardness when processed at $1100^{\circ}C$ . These results are comparable to the v…
Demand for healthy foods has increased substantially over the recent years due to growth in the world population and unhealthy lifestyles. One approach that could help to address this problem is the development of structures that offer high volume to energy content ratio. Techniques that could offer the necessary micr…
4 mol% Yttria-stabilized zirconia (4YSZ) coatings with $200{\mu}m$ thick are fabricated by Electron Beam Physical Vapor Deposition (EB-PVD) for thermal barrier coating (TBC). $150{\mu}m$ of NiCrAlY based bond coat is prepared by conventional APS (Air Plasma Spray) method on the NiCrCoAl alloy substrate before depositi…
