Diffusion welding of nickel-based superalloys [PDF]

, 2011
Ni based superalloys can be welded by diffusion bonding. Temperature, diffusion coefficient, activation energy and Boltzmann constant influence the quality of diffusion bonding, so obtaining the best condition for welding is considered.

Driven diffusion in nanoscaled materials [PDF]

, 2015
Mass transfer processes in which specific interactions with environments lead to complex diffusion patterns, such as the occurrence of transient sub-diffusive behaviors or of heterogeneous diffusion, were studied by means of two different experimental ...

Dispersive Transport Described by the Generalized Fick Law with Different Fractional Operators

Fractal and Fractional, 2020
The approach based on fractional advection–diffusion equations provides an effective and meaningful tool to describe the dispersive transport of charge carriers in disordered semiconductors.

Spin-diffusions and diffusive molecular dynamics [PDF]

Modelling and Simulation in Materials Science and Engineering, 2017
Abstract Metastable configurations in condensed matter typically fluctuate about local energy minima at the femtosecond time scale before transitioning between local minima after nanoseconds or microseconds. This vast scale separation limits the applicability of classical molecular dynamics (MD) methods and has spurned the development

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The application of frequency-domain photoacoustics to temperature-dependent measurements of the Grüneisen parameter in lipids

Photoacoustics, 2018
The Grüneisen parameter is an essential factor in biomedical photoacoustic (PA) diagnostics. In most PA imaging applications, the variation of the Grüneisen parameter with tissue type is insignificant.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Effective diffusion tensor computed by homogenization [PDF]

, 2013
The convergence of the long-time apparent diffusion tensor of diffusion magnetic resonance imaging (dMRI) to the effective diffusion tensor obtained by mathematical homogenization theory was considered for two-compartment geometric models containing non ...

A new experimental result indicating 3 separate phase fields of ε, ε1, ε2 and the estimation of diffusion coefficients in the Mn–Zn system

Journal of Alloys and Metallurgical Systems
The Mn–Zn system, technologically crucial for galvanized Mn–containing steels and potential ZnMn–based biomaterials, has been studied using the conventional diffusion couple technique.
