Hybridization on DNA‐Coated Ultrasmall Gold Nanoparticles (2 nm)

Chemistry – A European Journal, EarlyView.
DNA‐conjugated ultrasmall gold nanoparticles (2 nm) hybridize with complementary DNA strands to form dimers. Covalent attachment via click chemistry preserves the DNA functionality, creating building blocks for supramolecular chemistry and controlled nanoparticle assembly.

Variability of a Non‐Centrosymmetric Tecto‐Borosulfate: Introduction of Various Molecular Cations into BiX[B(SO4)2]4 (X  =  H3O+, NO2+, NH4+, NO+)

Chemistry – A European Journal, EarlyView.
To date, Bi(H3O)[B(SO)2]4 is only the second structure type containing a 3D anion within borosulfate chemistry. In this contribution three more representatives were synthesized, formally replacing oxonium by the molecular cations nitrosonium, nitronium, and ammonium. The structures crystallize homeotypically to the very first compound.

Experimental investigation of surface activity, micellization behaviour, and enhanced oil recovery performance of saponin‐based green surfactants

The Canadian Journal of Chemical Engineering, EarlyView.
This graphical abstract illustrates the steps carried out in the laboratory study, including saponin modification and characterization, surface tension, interfacial tension, contact angle, adsorption, and surfactant injection tests. Abstract In this study, three forms of saponin surfactants extracted from the Camellia sinensis plant (CS1, CS2, and CS3)
