Tunable poly(hydroxyl urethane) from CO2‐Based intermediates using thiol‐ene chemistry
CO2-based, crosslinked poly(hydroxyl urethane)s (PHUs) are accessed via a set of efficient reactions based on the addition chemistry of thiol-ene and amines-cyclic carbonates. This strategy to…

The melt polymerization of diglycerol with bicyclic anhydride monomers derived from a naturally occurring monoterpene provides an avenue for polyesters with a high degree of sustainability and represents key factors in the design of these sustainable polyesters.
Selective gelation of N-(4-pyridyl)nicotinamide by copper(II) salts
We report the selective gelation properties of the copper(II) complexes of N-(4-pyridyl)nicotinamide (4PNA). The morphology of the xerogels was examined by scanning electron microscopy (SEM). The…
Tuning Gel State Properties of Supramolecular Gels by Functional Group Modification
The solvated forms of mono-N-oxides support the fact that these compounds prefer crystalline state rather than gelation due to the increased hydrophilic interactions.

The structure and dynamics for CO2 absorption in ionic liquid reverse micelle (ILRM) were studied using molecular simulations and found that the [bmim][BF4] IL inside the RM diffuses 5-26 times faster than the neat IL, which is partly due to the fast particle diffusion for the ILRM nanodroplet (IL and surfactant) as a whole in benzene solvent compared with neat [BMim][ BF4] diffusion.
