Spectral Analyses of a Novel Ibuprofen-Phillygenin Ester

open access: yesChinese Journal of Magnetic Resonance, 2018
An ibuprofen-phillygenin ester was synthesized through the Schotten-Baumann reaction with ibuprofen and phillygenin as the starting materials. Ultraviolet absorption (UV) spectrum, infrared absorption (IR) spectrum, matrix-assisted laser desorption ...

Classical dimers on the triangular lattice [PDF]

open access: yes, 2002
We study the classical hard-core dimer model on the triangular lattice. Following Kasteleyn's fundamental theorem on planar graphs, this problem is soluble by Pfaffians.

Equilibrium Properties of A Monomer-Monomer Catalytic Reaction on A One-Dimensional Chain [PDF]

open access: yes, 2003
We study the equilibrium properties of a lattice-gas model of an $A + B \to 0$ catalytic reaction on a one-dimensional chain in contact with a reservoir for the particles.

A CO2-switchable amidine monomer: synthesis and characterization

open access: yesDesigned Monomers and Polymers, 2017
Smart system employed CO2 gas as new trigger has been attracting enormous attention in recent years, but few monomers that are capable of switching their hydrophobicity/hydrophility upon CO2 stimulation have been reported. A novel CO2 responsive monomer,

Monomer-Induced Customization of UV-Cured Atelocollagen Hydrogel Networks

open access: yesFrontiers in Chemistry, 2018
The covalent functionalization of type I atelocollagen with either 4-vinylbenzyl or methacrylamide residues is presented as a simple synthetic strategy to achieve customizable, cell-friendly UV-cured hydrogel networks with widespread clinical ...
