Combined Foaming and Surface Structuring of Polymers With Supercritical Carbon Dioxide (scCO2) Applying an Incomplete Saturation Strategy

Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Combined foaming and structuring of polymer samples by processing with supercritical CO2 leads to nano‐ and microstructured surfaces on top of perfectly white polymer sheets. ABSTRACT Supercritical carbon dioxide (scCO2) is a widely applied solvent utilized in many physical–chemical processes, including the foaming or structuring of polymers.

Solvothermal Fabrication of Trimetallic Oxides NCs: Exploring Their Magnetic and Photocatalytic Characteristics

Nano Select, Volume 7, Issue 4, April 2026.
A trimetallic NiFe2O4/ZnO/Co3O4 nanocomposite is synthesized via a solvothermal route and thermally tuned by post‐annealing. Structural, optical, and magnetic properties evolve systematically with temperature, enabling efficient sunlight‐driven degradation of mixed organic dyes.

Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...
