Article Abstract
In this study, the influence of annealing on the phase evolution and mechanical properties of the FeNiPC (at.%) alloy was investigated. Ribbons produced via melt-spinning were annealed at various temperatures, and their structural transformations and hardness were evaluated. The alloy exhibited a narrow supercooled liquid region (ΔT ≈ 22 °C), confirming its low glass-forming ability (GFA). Primary crystallization began at approximately 380 °C with the formation of α-(Fe,Ni) and FeNiP, followed by the emergence of γ-(Fe,Ni) phase at higher temperatures. A significant increase in hardness was observed after annealing up to 415 °C, primarily due to nanocrystallization and phosphide precipitation. Further heating resulted in a hardness plateau, followed by a noticeable decline. Additionally, samples were produced via selective laser melting (SLM). The microstructure of the SLM-processed material revealed extensive cracking and the coexistence of phosphorus-rich regions corresponding to FeNiP and iron-rich regions associated with γ-(Fe,Ni).

With growing public attention to environmental issues and sustainable development, biodegradable bio-based plastics have attracted widespread interest. This study reveals the chemical-physical synergistic regulation mechanism of biodegradable PLA/PBAT blends through the synergistic modification of epoxidized natural rubber (ENR) and epoxy chain extender (ADR). Interfacial interaction analysis shows that PBAT tends to encapsulate ENR to form aggregates.

Effective removal of ethylene (CH) during fruit and vegetables storage and transport remains a critical challenge for post-harvest preservation. Although S-scheme heterojunctions can improve charge separation and redox capacity for ethylene degradation, their efficiency is still restricted by limited carrier transfer and sluggish oxygen activation. Here, we rationally designed a novel 2D/2D SnNbO/BiMoO monolayer S-scheme heterojunction integrated with Pt co-catalyst to address these limitations.

Titanium dioxide (TiO) thin films were deposited on glass substrates under HV conditions at room temperature by the physical vapor deposition method. Produced titanium thin films were post-annealed at 573 K at different oxygen flows (0, 9 and 23 cm/s). The influence of different oxygen flows on nano-structure, crystallography, and optical parameters of TiO films was investigated by XRD, AFM, and spectrophotometer in the UV-VIS wavelength range.

The scalable fabrication of high performance dyes desalination loose nanofiltration (LNF) membrane through facile thermal annealing remains challenging due to the susceptible pore collapse. Herein, we have developed a metal ion mediated sub-Tg thermal crosslinking protocol, which can convert the phase inverted reactive polymeric ultrafiltration substrate into LNF membrane showing high permselectivity as well as resistance to both extremely acid and alkaline solution. The original ultrafiltration substrate was composed of scalable-produced reactive polyarylene ether amidoxime (PEA) that was pre-crosslinked with ferric ions.
