Fusion of neuraminidase or trypsin pretreated human erythrocytes and untreated cells was performed. The obtained doublets had a permanent dipole moment which disappeared as a function of time. Since the dipole moment disappearance is due to protein interdiffusion the lateral diffusion constant may be determined. This was performed by fixing fused cells in different time intervals following the ...

The photonic bandgap of periodic multilayers with diffuse interface is calculated by considering an empirical model for the interdiffusion profile. The model for the diffuse profile is based on the error function Erf and a characteristic parameter σ. The model is valid for multilayer structure with arbitrary layer thickness. It is shown that the width of the bandgap varies with the value of σ a...

Platinum-diffused γ+γ' coatings (~20 at.% Al, ~22 at.% Pt) were synthesized on René 142 and René N5 Ni-based superalloys by electroplating the substrates with ~7 μm of Pt, followed by an annealing treatment in vacuum at 1175°C. In order to study the compositional and microstructural evolution of these coatings at elevated temperatures, interdiffusion experiments were carried out on coated speci...

Needs in more-efficient visible light sources based on quantum wells (QWs) requires the diversification of traditional optoelectronics’ materials as well as development of the cost-effective approaches for reliable quantum confinement engineering. Interdiffusion approach has a great potential to become a simple method for controlling the optical properties of QWs and diminishing the quantum con...

The effects of different rapid thermal annealing temperatures on the optical properties of InAs double quantum dots (DQDs) grown by molecular beam epitaxy using a partial-capping-and-regrowth process have been investigated. Improvement of the material quality is indicated by enhanced photoluminescence (PL) intensity and narrower PL linewidth. The blueshift of the PL emission peak with increasin...

blown bitumen (110/10) was mixed with heavy vacuum slops (h.v.s), 60/70 penetration grade bitumen and recycled isotactic polypropylene (ipp) at different levels. the resulting resins were used to impregnate non-woven poly(ethylene terephthalate) fibers to form composites. the modulus and penetration grade of the resulting bituminous resins were determined. it was found that these bituminous res...

Interdiffusion in Ti-rich β solid solutions Ti–Al–Zr alloys was investigated at 1473 K. In the alloys, main interdiffusion coefficients (i.e., and , respectively) cross coefficients, have positive values, as well a slight concentration dependence. The values of are larger than those . Ti–Al–X (= V, Cr, Fe, Co, Zr) Repulsive interactions occur between Al X atoms because ratio to ones sign. On ot...

Radiotracer techniques were used to study the influxes and effluxes of various univalent cations in internally perfused squid giant axons. Membrane currents and conductances were determined by the voltage-clamp technique under analogous internal and external conditions. Both sodium-containing and sodium-free internal and external media were studied. Membrane impedance was measured with an ac im...
