The unusual geometry of spiral nanocrystals gives rise to unique optical, electronic, and mechanical properties. Spiral growth of noble metals was demonstrated for gold decades ago but no information about silver nanospirals was reported. Here present novel approach for preparation of silver nanospirals with yields of over 90%, based on application of 3-mercaptopropionic acid (MPA) ligand....

Alkali-activated composites based on fly ash (FA) and metakaolin (MK) were designed as sustainable low-carbon construction materials. The fly ash was mechanically activated in a planetary mill for 20 min to enhance its reactivity, while metakaolin was produced by the thermal treatment of kaolin at 700 °C for 2 h. Sodium hydroxide and sodium silicate solutions were used as alkaline activators....

Ordinary Portland cement (OPC) production significantly contributes to global greenhouse gas emissions . Geopolymers synthesized from metakaolin offer an eco-friendly alternative, though unreinforced matrices can exhibit microstructural brittleness under load . Incorporating fiber reinforcement enhances mechanical performance and structural behavior . This study analyzed the effect of...

The construction sector is under increasing pressure to reduce greenhouse gas emissions, decrease its reliance on virgin raw materials, and implement circular economy principles. The valorization of recycled concrete fines (RCF) as a supplementary cementitious material offers a promising route for reducing clinker consumption and natural raw materials, lowering the carbon footprint of...

Screen-printed carbon electrodes (SPCEs) are crucial for point-of-care diagnostics but often require surface modification to meet clinical sensitivity demands. This study presents the development of high-performance electrochemical sensors utilizing reduced graphene oxide (rGO) decorated with gold nanoparticles (AuNPs) at varying concentrations (0.5, 2, and 4 wt.%). Structural and thermal...

To develop sustainable functional polymer-lignin composites, the lignin was modified with zwitterionic (L)/3-[(2-methacryloyloxy)ethyl]dimethylammonio propane sulfonate (DMAPS) oligomers grafted in situ from its surface in different mass ratios (1:1, 1:2, and 1:3) via an UV-induced thiol–ene reaction. Successful surface functionalization was confirmed by FTIR, XPS, and colloidal analysis. The...
