We investigate the effect of topology on the equilibrium behavior of singly tethered ring polymers adsorbed on an attractive surface. We focus on the change of square radius of gyration Rg(2), the perpendicular component Rg⊥(2) and the parallel component Rg‖(2) to the adsorbing surface, the mean contacting number of monomers with the surface

Electrocatalytic synthesis of high-value chemicals has been attracting growing interest owing to its environmentally benign reaction pathways. Among these processes, the electrocatalytic reduction of nitrate (NO3-) to ammonia (NH3), known as NO3RR, and the oxidation of 5-hydroxymethylfurfural (HMFOR) stand out as two cornerstone reactions; yet, their efficiency and selectivity pose ongoing challenges. In this study, we introduce a charge manipulation approach for the design of highly efficient electrocatalysts tailored for the simultaneous coupling of NO3RR and HMFOR.

The retention time of a polymer in liquid chromatography depends on the details of its microstructure and topology. Despite the number of separation modes and methods available for polymers, gaining quantitative information from chromatograms remains a challenge. A model able to predict the LC retention time of a polymer accounting for all possible variations in its microstructure could provide some valuable insight during method development and produce the information necessary to establish unambiguous structure/property relationships.
