ASSEMBLY OF PLANAR CHIRAL SUPERLATTICES FROM ACHIRAL BUILDING BLOCKS
20230249966 · 2023-08-10 ·

The spontaneous assembly of chiral structures from building blocks that lack chirality is fundamentally important for colloidal chemistry and has implications for the formation of advanced optical materials. Here, we find that purified achiral gold tetrahedron-shaped nanoparticles assemble into two-dimensional superlattices that exhibit planar chirality under a balance of repulsive electrostatic and attractive van der Waals and depletion forces. A model accounting for these interactions shows that the growth of planar structures is kinetically preferred over similar three-dimensional products, explaining their selective formation.

Facile method for the large area synthesis of geometrically two dimensional metals and ceramics

A new technique, referred to as PSBEE, is disclosed and enables fabrication of freestanding nanomembranes. The PSBEE technique enables fabrication and synthesis of nanomembranes comprising 2D high entropy alloys and 2D metallic glasses and may be extended to ceramics and semiconductors, thereby enabling the fabrication of large-scale freestanding nanomembranes across a wide range of materials, including those deemed to have a great potential for future functional and structural use. To form nanomembranes using PSBEE, a plurality of membranes may be prepared and subjected to thermoplastic compression. Afterwards, one of the membranes may be removed and the remaining membranes may undergo additional thermoplastic compression in the presence of a Si substrate. Once a threshold level of smoothness is achieved, a coating or film may be applied and then separated from the final plate.
