Scientific Reports, Published online: 12 September 2026; doi:10.1038/s41598-026-70102-7 Influence of alkaline activator concentration on the mechanical, microstructural properties of geopolymer mortar using Class C fly ash and M-sand

Polyether ether ketone (PEEK) composites face concurrent ultraviolet (UV) and thermo-oxidative aging in real-world service environments, yet the synergistic effects remain poorly understood. This study systematically decouples the degradation pathways of three PEEK-based materials--neat PEEK (PK), 30 wt% CF-reinforced PEEK (UG), and PTFE/Gr/CF-modified PEEK (VMT)--under isochronal (1500 h) UV and…

Rough finishes, limited wear resistance, and poor adhesion to protective coatings can restrict polymer use in demanding applications. Researchers have demonstrated that carefully engineered metal and ceramic multilayer coatings can overcome these limitations, giving commonly used polymers tougher, more durable surfaces.

Nature Water, Published online: 09 September 2026; doi:10.1038/s44221-026-00644-7 The ocean contains a vast reserve of uranium that could satisfy global demand for generations. A newly proposed covalent organic framework utilizes structural asymmetry to increase uptake rates, enabling more efficient oceanic uranium recovery.

Nature Water, Published online: 09 September 2026; doi:10.1038/s44221-026-00685-y Enhancing charge separation and directing photogenerated electrons to active sites remain key challenges in photocatalytic uranium extraction. Localized potential well engineering in bipyridine-containing covalent organic frameworks enables directional electron transport, achieving a uranium extraction capacity of 8…

In the Journal of Applied Physics, researchers explore an eggshell-inspired design as a potential spacecraft protection material. It may seem counterintuitive to use eggshells as a blueprint for strength, but they found that organizing water-filled aluminum eggshells into an array adds useful material properties when placed blunt side down between two aluminum impact plates. Rather than being con…

Rare-earth oxides such as cerium oxide, lanthanum oxide, and yttrium oxide can improve laser-cladded metal coatings by refining grains, purifying the molten pool, strengthening interfaces, and altering solidification behavior. The review finds that these effects can increase hardness, wear resistance, corrosion resistance, and crack resistance, although performance depends strongly on additive co…

Engineers have developed a faster way to manufacture carbon-carbon composites, exceptionally strong materials used to protect spacecraft and high-speed vehicles from extreme heat. The new method could reduce production time from several months to only a few days. The technique was created by engineers at the Johns Hopkins Applied Physics Laboratory in Maryland. Called FAST […] The post Engineers …

Researchers first screened steel-fiber geometry and length for concrete impermeability, identifying 50-mm hooked-end and 40-mm crimped fibers as the best performers among those tested, before combining them with nano-silica to assess 28-day mechanical properties and microstructure. The hybrid mixtures performed best at 2% steel fiber and 1% nano-silica among the tested levels, with hooked-end fib…

Epoxy is one of the great unifiers of modern materials science, bringing different materials together to form composites with combined properties that exceed those of any individual component. The problem is that once conventional epoxy cures, the resulting union is practically permanent. Separating the constituent materials for recycling can be extremely difficult.

The combined properties of reduced graphene oxide/polypyrrole (rGO/Ppy) have drawn a lot of interest in composite electrodes for supercapacitors. In this work, chemical bath deposition (CBD) method was used to develop rGO/Ppy composite thin films. The CBD method enables the synthesis of self-supported electrode materials, optimizing the physicochemical characteristics and promoting efficient char…
