Seismic Fragility Analysis of Containment Structures in Nuclear Power Plants Considering Alkali‐Silica Reaction

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Mechanophoric 3‐Arm Star Functional Block Copolymer Based on Rhodamine Derivative

Macromolecular Materials and Engineering, EarlyView.
Mechanoresponsive rhodamine containing linear and star block and random copolymers were synthesized and characterized. All materials transitioned into a “switch‐on” state in the film form, but only the star block copolymer architecture exhibited a complete and precise peak shift upon stretching, providing new insights into the mechanochemical ...

Molecular phylogenetic and morphological analyses revealed a new species, Leucocoprinus roseus (Agaricaceae, Basidiomycota), from Punjab, Pakistan

Nordic Journal of Botany, EarlyView.
In this article, we describe a new fungal species, Leucocoprinus roseus, collected in Canal View Park, District Mandi Bahauddin, Punjab, Pakistan. The species is proposed as new based on detailed morphological observations and molecular phylogenetic analysis using nuclear ribosomal DNA internal transcribed spacer (nrITS) sequences.
