Preparation of High‐Pressure Laminate With Bio‐Based Fructose‐HMF‐Amine Impregnation Resin
This study demonstrates the use of a resin made from renewable carbohydrates, free from phenol and formaldehyde, for impregnating recycled kraft paper to produce high‐pressure laminates. The resulting bio‐based laminate samples match the mechanical performance of conventional phenol‐formaldehyde‐based samples, highlighting their potential to replace ...

Analysis of Steam Line Break Accident Using PCTRAN Model of VVER-1200 NPP
The investigation of thermal-hydraulic parameters during steam-line break (SLB) accidents is performed by applying the personal computer transient analyzer (PCTRAN) simulator model of the VVER-1200 nuclear power plant (NPP). Five cases, namely, 0.005 m2 (

Alendronate‐based copolymers for Nd and Ce recovery. ABSTRACT Bisphosphonic acid groups are emerging as promising functionalities for actinide decontamination, due to their high density of chelating sites. However, the chemistry of bisphosphonate (in particular alendronate) materials remains complex and underexplored.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Potential Impacts of Climate Interventions on Marine Ecosystems
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

Estimation of Control Rod Worth in a VVER-1000 Reactor using DRAGON4 and DONJON4
One of the main issues in safety and control systems design of power and research reactors is to prevent accidents or reduce the imposed hazard. Control rod worth plays an important role in safety and control of reactors.
