Summary: The conception, synthesis, and invention of spherical nucleic acid (SNA) in 1996 created a new field of chemistry. Over the past three decades, SNAs and their anisotropic equivalents have led to technological advancements in various fields by providing new perspectives on fundamental concepts in chemistry. One notable application is colloidal crystal engineering with DNA, which allows for the synthesis of programmable matter. This article documents the evolution of this framework, inspired by nature, and explores its potential for creating programmable matter with real-world significance.

Summary: The study on partial cation exchange of roxbyite copper sulfide nanoparticles revealed unique exchange products and showed that substoichiometric amounts of Zn2+ can limit the initiation and propagation of exchange reactions. These insights can expand the diversity of intraparticle frameworks in spherical nanoparticles to produce a broader range of heterostructured products downstream.

Summary: Covalent organic framework (COF) membranes function as adsorbents rather than size-sieving membranes. Adsorption of various dyes by COFs shows high capacity and diverse affinities, driven by variable entropic gains. Further examination of the COF membrane literature is necessary, as separations based on differential transport through 2D COF pores remain an important yet unrealized frontier.

Summary: This study reports the conversion of alpha-chalcocite copper sulfide nanorods to weissite copper telluride nanorods through anion exchange, revealing unique dynamic exchange characteristics and complex structures produced. Unusually, no voids were observed in the product nanoparticles during the exchange process, attributed to the balancing of inward and outward anion diffusion through nanoscopic pathways that formed defects. This mechanism creates new opportunities for rational synthesis of complex nanoheterostructures.

Summary: This study examined the effect of particle surface properties on ice nucleation and growth by synthesizing materials with tunable surface properties. The results showed that COFs with a pore diameter between 2 and 3 nm exhibited the most efficient ice nucleation activity among all the highly crystalline COFs. It was also observed that the highly crystalline structures with ordered pores have an optimal pore diameter for maximizing ice nucleation activity.

Summary: We present predictive guidelines for substoichiometric cation exchange of two-component metal sulfide nanorods containing similar hardness divalent cations. Unit cell volume changes, cation radii, solubility constants, and solid state interfaces influence the selectivity during Cu+ substoichiometric exchange when multiple products are possible.
