Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Advanced Engineering Materials, EarlyView.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

A Short Note On Solving 1-D Porous Medium Equation by Finite Element Methods [PDF]
, 2016 Porous Medium Equation (PME) is one of the simplest types of of nonlinear evolution equation of parabolic type. It emerges in the description of di erent natural phenomena, and its theory and properties depart strongly from the heat equation, ut = u ...

The mesa problem for the fractional porous medium equation
Interfaces and Free Boundaries, Mathematical Analysis, Computation and Applications, 2015 We investigate the behaviour of the solutions u_m(x,t) of the fractional porous medium equation u_t+(-\Delta)^s (u^m)=0, \quad x\in \mathbb R^N, \ t>0

The porous medium equation in one dimension [PDF]
Transactions of the American Mathematical Society, 1977 We consider a second order nonlinear degenerate parabolic partial differential equation known as the porous medium equation, restricting our attention to the case of one space variable and to the Cauchy problem where the initial data are nonnegative and have compact support consisting of a bounded interval.

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam
Advanced Engineering Materials, EarlyView.Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

NUMERICAL METHODS WITH INTERFACE ESTIMATES FOR THE POROUS MEDIUM EQUATION* [PDF]
, 1987 . We provide a general basis, based on the weak truncation error, for proving L ∞ error bounds for the porous medium equation in one space dimension. We show how such bounds for the solution can lead to estimates for the interface of the support for the ...
