Uniqueness of limiting solution to a strongly competing system
Electronic Journal of Differential Equations, 2017 We prove a uniqueness for the positive solution to a strongly competing system of Lotka-Volterra type problem in the limiting configuration, when the competition rate tends to infinity.

Advanced Engineering Materials, EarlyView.This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Free Boundary Problems and Density Perimeter
Journal of Differential Equations, 1996 This paper is devoted to study the existence of optimal domains which minimize the domain energy functional \(\Omega\to E(\Omega)\). Special cases are studied in which a family of open subsets of a fixed bounded set is compact in the char-topology defined on the family of measurable subsets of \(\mathbb{R}^n\) by the \(L^2\)-matrix, and in which the ...

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

One-Dimensional Parabolic Free Boundary Problems [PDF]
SIAM Review, 1977 Frequently, diffusion processes require the determination of a free surface from overprescribed boundary data. A commonly used constructive solution technique for such problems is the method of straight lines. This paper illustrates the steps involved in the solution process. Specifically, the method of lines is used to approximate various explicit and
