Polymer Chemistry 2015: Real Time Quantification of the Chemical Cross-Link Density of a Hydrogel by in situ UV-vis Spectroscopy
In this paper, we prepare a hydrogel in a green way via the redox reaction between phenol groups and EosinY by visible light irradiation. Eosin Y shows significant absorption at 515 nm while the reduced product does not. A series of control experiments show that almost 100% of the consumed Eosin Y is reacted with phenol groups to form cross-link points. On the basis of the two results, the chemica...

Phys. Chem. Chem. Phys., 2010: The Possible Roles of Water in the Prebiotic Chemical Evolution of DNA
There
is no doubt that water is pivotal to life. Yet, as the emergence of life is
still a big challenge in science, the detailed involvement of water in that
process is not well recognized. Following the clues provided by recent
single-molecule studies on DNA, we attempt to elucidate the possible roles of
water in the prebiotic chemical evolution. Water has been long recognized as an
important rea...

Effect of Chemical Treatments on Transverse Thermal Conductivity of Unidirectional Abaca Fiber/Epoxy Composite
Present paper investigated the effect of mercerization and silane treatments on the transverse thermal
conduction properties of unidirectional abaca fiber–epoxy composite fabricated by resin transfer molding.
As indicated by FTIR, XRD and SEM, the changes in chemical composition, crystalline and lumen
structure of abaca fibers were introduced by chemical treatments. Transverse tensile test showed...

Toward interconnected hierarchical porous structure via chemical depositing organic nano-polyaniline on inorganic carbon scaffold for supercapacitor
In this article, the composites of organic nano-polyaniline (nano-PANI)/interconnected inorganic carbon scaffold (C-scaffold) were prepared via in-situ chemical polymerization. The structures and morphologies were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), and the electrochemical behaviors were carried out in 1 M H2SO4 aqueo...

Vibrational Activity Change of Self-Assembled Monolayers upon Chemical Attachment and Nanoscale Block Revealed by Surface Enhanced Raman Spectroscopy
This paper presents an experimental framework aiming at identifying the origin of weak ambiguous vibrational modes in surface enhanced Raman scattering (SERS), i.e. from the high-order effect or symmetry change using 1,4-benzenedithiol (BDT) as probing molecules. The experimental result indicated the appearance of the weak ambiguous vibrational modes was caused by symmetry change rather th...

Mg2+/Ca2+ binding to DNA bases: a quantum chemical method and ABEEMrp/MM fluctuating charge model study
The interactions of Mg2+ and Ca2+ binding to adenine, cytosine, guanine, and thymine at various binding sites were studied by a high-level quantum chemical method and ABEEMrp/MM fluctuating charge model. The geometries and binding energies of M2+-bases complexes were determined at CCSD(T)/6-311++G(2d,2p)//MP2/6-311++G(2d,2p) level of theory, with the basis set&nb...
