Kinetics of Nickel Diffusion into Austenitic Stainless Steels AISI 304 and 316L and Calculation of Diffusion Coefficients.
Publication Type: Academic Journal
Source(s): Materials (1996-1944). Oct2023, Vol. 16 Issue 20, p6783. 17p.
Abstract: Diffusion bonding has many advantages, but it also has its specifics. When creating heterogeneous joints, problems arise with the creation of intermetallic phases. For this reason, an interlayer is needed to prevent the creation of these unfavorable ph...
Moisture Diffusion Coefficient of Concrete under Different Conditions.
Publication Type: Academic Journal
Source(s): Buildings (2075-5309). Oct2023, Vol. 13 Issue 10, p2421. 25p.
Abstract: Humidity change in concrete is the leading cause of concrete shrinkage. Moreover, the moisture diffusion coefficient of concrete is an essential parameter for assessing and predicting the internal moisture content of concrete. However, there is a lack ...
An Experimental Approach to Determining the Average Diffusion Coefficient of Volatile Components in Polymer Waste Materials.
Publication Type: Academic Journal
Source(s): Recycling (MDPI AG). Oct2023, Vol. 8 Issue 5, p72. 19p.
Abstract: One of the major challenges in recycling plastics is the removal of undesired volatile components from the polymeric phase, which may reduce process efficiency and negatively affect product quality. Accordingly, the recycling industry employs a broad r...
Diffusion of LiCl electrolytes in 3D-nanoporous graphene structures.
Publication Type: Academic Journal
Source(s): Journal of Applied Physics. 10/14/2023, Vol. 134 Issue 14, p1-10. 10p.
Abstract: In this work, we investigate the diffusion of LiCl electrolytes in 3D-nanoporous graphene structures (3D-NGSs) through molecular dynamics simulations. The diffusion coefficients, D, of water, Li+, and Cl− are calculated in 3D-NGSs with different LiCl c...

Analysis of Diffusion Coefficients of Iron Monoboride and Diiron Boride Coating Formed on the Surface of AISI 420 Steel by Two Different Models: Experiments and Modelling.
Publication Type: Academic Journal
Source(s): Materials (1996-1944). Jul2023, Vol. 16 Issue 13, p4801. 31p.
Abstract: In the present work, two mathematical diffusion models have been used to estimate the growth of the iron monoboride and diiron boride coating formed on AISI 420 steel. The boronizing of the steel was carried out with the solid diffusion packing method ...
Effect of Soil Volumetric Water Content on the CO 2 Diffusion Coefficient.
Publication Type: Academic Journal
Source(s): Sustainability (2071-1050). Aug2023, Vol. 15 Issue 16, p12637. 15p.
Abstract: Purpose: The soil air diffusion coefficient (Ds) is particularly important for the study of soil gas diffusion movement, and there are still many uncertainties in the widely used methods; as such, a method was designed to in situ measure the soil gas d...

Abstract: The diffusion coefficient data of materials are crucial for several applications, and can be calculated theoretically up to considerable accuracies. Using molecular dynamics simulation it is possible to compute this property for several conditions as t...
Front propagation in ultrastable glasses is dynamically heterogeneous.
Publication Type: Academic Journal
Source(s): Journal of Chemical Physics. 9/21/2023, Vol. 159 Issue 11, p1-12. 12p.
Abstract: Upon heating, ultrastable glassy films transform into liquids via a propagating equilibration front, resembling the heterogeneous melting of crystals. A microscopic understanding of this robust phenomenology is, however, lacking because experimental re...
Non-Markovian effects of conformational fluctuations on the global diffusivity in Langevin equation with fluctuating diffusivity.
Publication Type: Academic Journal
Source(s): Journal of Chemical Physics. 8/7/2023, Vol. 159 Issue 5, p1-6. 6p.
Abstract: Local diffusivity of a protein depends crucially on the conformation, and the conformational fluctuations are often non-Markovian. Here, we investigate the Langevin equation with non-Markovian fluctuating diffusivity, where the fluctuating diffusivity ...
