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.

Modules With Epimorphisms Between Their Submodules

Journal of Mathematics
An R-module M is called weakly uniserial if its submodules are comparable regarding embedding, i.e., if for any two submodules N, K of M, HomRN,K or HomRK,N contains an injective element.

Relative $C$-$(n,m)$-cotorsion modules [PDF]

Journal of Mahani Mathematical Research
‎Let $R$ be a ring‎, ‎$C$ a (faithfully) semidualizing module‎, ‎and $n‎, ‎m \geq 0$ be integers or potentially $n = \infty$‎. ‎We introduce and analyze $C$-(n,m)-cotorsion modules‎, ‎utilizing the class of $R$-modules with $C$-$FP_n$-flat dimensions at ...

FP-injectivity of factors of injective modules

, 2015
International audienceIt is shown that a ring is left semihereditary if and only each homomorphic image of its injective hull as left module is FP-injective. It is also proven that a commutative ring R is reduced and arithmetical if and only if E/U if FP-

Rotary 3D Printing With Integrated Electroplating

Advanced Engineering Materials, EarlyView.
A rotary material extrusion platform integrates localized copper electroplating with printing and encapsulation to fabricate cylindrical polymer–metal structures containing fully embedded, low‐resistance conductive pathways that enable internal Joule heating and thermally activated shape‐memory responses.

Left global dimensions and inverse polynomial modules

International Journal of Mathematics and Mathematical Sciences, 2000
We prove the fact l.gl.dimR[x]=(l.gl.dimR)+1, where l.gl.dim means the left global dimension by using inverse polynomial modules and injective dimensions.

Investigating modules with partial endomorphisms having μ-small kernels [PDF]

Journal of Mahani Mathematical Research
In this paper, we introduce and study the concept of generalized monoform modules ($G-M$ modules, for short) which is a proper generalization of that of monoform modules. We present some of their examples, properties and characterizations.

Weakly Projective and Weakly Injective Modules

, 1994
A module M is said to be weakly N-projective if it has a projective cover π: P(M) ↠M and for each homomorphism : P(M) → N there exists an epimorphism σ:P(M) ↠M such that (kerσ) = 0, equivalently there exists a homomorphism :M ↠N such that σ= .

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

Weakly Relative Quasi-Injective Modules

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
    Let R be a commutative ring with unity and let M, N be unitary R-modules. In this research, we give generalizations for the concepts: weakly relative injectivity, relative tightness and weakly injectivity of modules.
