Nature, through billions of years of evolution, has constructed extremely efficient biosystems for transporting, confining, and vaporizing water. Mankind's ability to master water, however, is far from impeccable, and a sustainable supply of clean fresh water remains a global challenge. Here, we learn from Nature and prepare papyrus carbon (PC) from Egyptian papyrus paper as a sustainable solar desalination material.

- Researchers focused on thin gold nanowires synthesize long, ultrathin versions using liquid-phase methods and in situ high-energy X-ray diffraction to uncover their formation mechanisms.
- They discovered that the growth of these nanowires involves transient linear gold complexes that self-assemble under controlled conditions, differing from the typical structure of bulk gold.
- The unique tetrahedrally close-packed structure of these nanowires is attributed to geometrical frustration, affecting atomic packing and leading to cylindrical shapes, offering insights for future applications and synthesis methods.
Article Synopsis
- Gold nanowires with a tiny 1.7 nm diameter were created by reducing HAuCl in a hexane solution mixed with oleylamine.
- Analysis showed that the nanowires had a bilayer of oleylammonium chloride and oleylamine at their surface, which could be partially replaced by a phosphine layer without changing the nanowire shape.
- Different ligands impacted the nanowires' crystalline structure and stability, with phosphine-coated nanowires demonstrating longer-lasting properties compared to other coatings like thiols.
