Green synthesis, anionic polymerization of 1,4-bis(methacryloyl)piperazine using Algerian clay as catalyst

open access: yesGreen Processing and Synthesis, 2019
In this work, a chain of reactions has been proposed as a new heterogeneous technique, based on the use of natural treated clays as an environmentally friendly catalysts for the synthesis of poly(1,4-bis(methacryloyl)piperazine). We first synthesized the

Matching measure, Benjamini-Schramm convergence and the monomer-dimer free energy [PDF]

open access: yes, 2014
We define the matching measure of a lattice L as the spectral measure of the tree of self-avoiding walks in L. We connect this invariant to the monomer-dimer partition function of a sequence of finite graphs converging to L.

A systematic mutational analysis identifies a 5‐residue proline tag that enhances the in vivo immunogenicity of a non‐immunogenic model protein

open access: yesFEBS Open Bio, 2020
Poor immunogenicity of small proteins is a major hurdle in developing vaccines or producing antibodies for biopharmaceutical usage. Here, we systematically analyzed the effects of 10 solubility controlling peptide tags (SCP‐tags) on the immunogenicity of

Discrete and Stereospecific Oligomers Prepared by Sequential and Alternating Single Unit Monomer Insertion.

open access: yesJournal of the American Chemical Society, 2018
Natural biopolymers, such as DNA and proteins, have uniform microstructures with defined molecular weight, precise monomer sequence, and stereoregularity along the polymer main chain that affords them unique biological functions.

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,
