Synergistic effect of Mn + Sc additions on the microstructure evolution and mechanical properties of Mg-Gd-Y-Mn-Sc alloy

Journal of Materials Research and Technology, 2022
Mg-Gd-Y-Mn-Sc alloys with different Mn + Sc contents were prepared by hot extrusion and ageing treatment. The effect of Mn + Sc additions on the microstructures, tensile properties, and corresponding strengthening mechanisms of the as-extruded and peak ...

Dispersion of biased swimming microorganisms in a fluid flowing through a tube

, 2010
Classical Taylor-Aris dispersion theory is extended to describe the transport of suspensions of self-propelled dipolar cells in a tubular flow. General expressions for the mean drift and effective diffusivity are determined exactly in terms of axial ...

Dissolution and reprecipitation of 14H-LPSO structure accompanied by dynamic recrystallization in hot-extruded Mg89Y4Zn2Li5 alloy

Journal of Magnesium and Alloys, 2023
We investigate the variation induced in long-period stacking ordered (LPSO) structures, dynamic recrystallization (DRX), and mechanical performance of hot-extruded Mg89Y4Zn2Li5 alloys fabricated at different extrusion speeds (Ve = 0.4, 0.8, 1.0, 1.2 mm/s)

Vitamin C‐Assisted Synthesis of Novel Cu‐SSZ‐13 Zeolite and Its High‐Efficiency Performance in Diesel Vehicle NOx Exhaust Purification

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

The evolving therapeutic landscape of spinal muscular atrophy – A scoping review of investigational agents, emerging delivery technologies and strategic innovations

British Journal of Clinical Pharmacology, EarlyView.
Spinal muscular atrophy (SMA) is a severe neuromuscular disease with emerging therapeutic complexity. This review aims to systematically map the global pipeline of investigational treatments for SMA. Using ClinicalTrials.gov and complementary international registries, we identified 21 planned or ongoing interventional trials from 2020 to 2025 targeting

Applications of Balanced Pairs

, 2015
Let $(\mathscr{X}$, $\mathscr{Y})$ be a balanced pair in an abelian category. We first introduce the notion of cotorsion pairs relative to $(\mathscr{X}$, $\mathscr{Y})$, and then give some equivalent characterizations when a relative cotorsion pair is ...
