Preparation of High‐Pressure Laminate With Bio‐Based Fructose‐HMF‐Amine Impregnation Resin

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
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

open access: yesApplications of Modelling and Simulation, 2023
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 (

Development of Tunable Materials From Well‐Defined Alendronic Acid Functionalized Polyacrylamide: An Opportunity for Actinide Decontamination

open access: yesJournal of Polymer Science, Volume 64, Issue 6, Page 1431-1443, 15 March 2026.
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

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
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 ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
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.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

open access: yessteel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.
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

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
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 ...
