Rapid identification and quantification of panax notoginseng with its adulterants by near infrared spectroscopy combined with chemometrics
Traditional methods for identification of Panax notoginseng (PN) such as high performance liquid chromatography (HPLC) and gas chromatography (GC) are time-consuming, laborious and difficult to realize rapid and online analysis. In this research, the feasibility of identification and quantification of PN with rhizoma curcumae (RC), Curcuma longa (CL) and rhizoma alpiniae offcinaru...

[Macro. Rapid Commun.] Chitosan-based shape memory hydrogels with simultaneously switchable fluorescence behavior
Realization of shape memory process in polymeric hydrogels at ambient condition is a significant development to shape memory materials. The sound understanding of the dynamic shape memory process is fundamentally important but limited. Here, a novel shape memory hydrogel with simultaneously switchable fluorescence behavior is developed. The hydrogel is
prepared by incorporating a pH-responsive flu...

(Macromol. Rapid Commun)Fabricating Triple-Sensitive Polymer Nano- Aggregates via an Aqueous Iminoboronate Multicomponent Reaction
A triple-sensitive polymer of poly(ethylene glycol)-iminoboronate nitrobenzyl ethanediol
chelate (PEG-INEC) is efficiently fabricated via the convenient aqueous iminoboronate
multi-component reaction (MCR) of methoxypolyethylene glycol amine (mPEG-NH2), 2-formylphenylboronic acid (FPBA), and bis(2-nitrophenyl) ethanediol (BNPE, a photo-cleavable nitrobenzyl alcohol derivate). The aqueous M...

(Macromol. Rapid Commun)LCST-Type Hyperbranched Poly(oligo(ethylene glycol) with Thermo- and CO2-Responsive Backbone
A novel hyperbranched lower critical solution temperature (LCST) polymer with sharp temperature and CO2-responsive behaviors is presented in this study. The target polymer of hyperbranched poly(oligo(ethylene glycol) (HBPOEG) is constructed using POEG as the backbone and tertiary amines as branch points. Phase transition of HBPOEG in aqueous solution is investigated by heating and cooling the sy...

2018-Polym Test:Fully physical double network hydrogels with high strength, rapid self-recovery and self-healing performances
Double network hydrogels (DN gels) are one of most extensively investigated high strength hydrogels. However, conventional DN gels are fully chemically cross-linked, which often suffer from severe softening phenomenon and are lack of self-healing properties. In the present work, fully physically cross-linked Agar/PAAm DN gels, consisting of physical agar gel as the first network and physical polya...

Rapid and annealing-free self-assembly of DNA building blocks for 3D hydrogel chaperoned by cationic comb-type copolymers.
The construction and self-assembly of DNA building blocks are the foundation of bottom-up development of three-dimensional DNA nanostructures or hydrogels. However, most self-assembly from DNA components is impeded by the mishybridized intermediates or the thermodynamic instability. To enable rapid production of complicated DNA objects with high yields no need for annealing process, herein diffe...

【[Macromol. Rapid Commun]】A Novel Anisotropic Hydrogel with Integrated Self‐Deformation and Controllable Shape Memory Effect
Although shape memory polymers have been highlighted widely and developed rapidly, it is still a challenging task to realize complex temporary shapes automatically in practical applications. Herein, a novel shape memory hydrogel with the ability of self‐deformation is presented. Through constructing an anisotropic poly(acrylic acid)–polyacrylamide (PAAc–PAAm) structure, the obtained hydrogel ex...
