A Novel Polymer-Phenolic Prepolymer Based Blocking System for High- Temperature and High-Salinity Oil Reservoirs
Autor: Wang Xiaoxiang, Yang Wang, Fenfen Du, Wang Jian, Fan Hongwei, Jiang Yang
Publikováno v: Tenside Surfactants Detergents. 57:534-540
Focusing on the leakage problem in high temperature and high salinity oil fields (reservoir temperature 1208C-1308C, formation water salinity 220000 mg/L), a gel-blocking system is proposed using a polymer and a phenolic prepolymer. Specifically, it

Publikováno v: Tenside Surfactants Detergents. 57:382-388
We have studied the effect of NaCl and CaCl2 on phase behavior of foaming aqueous dispersions containing mixtures of silica nanoparticles (Ludox CL) and sulfobetaine (LHSB). At the evaluated ratio, the phase behavior results show that at a low CaCl2

Electrostatic frequency maps for amide-I mode of β-peptide: Comparison of molecular mechanics force field and DFT calculations
Autor: Fenfen Du, Kaicong Cai, Xuan Zheng
Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 183:150-157
The spectroscopy of amide-I vibrations has been widely utilized for the understanding of dynamical structure of polypeptides. For the modeling of amide-I spectra, two frequency maps were built for β-peptide analogue (N-ethylpropionamide, NEPA) in a

Mapping the amide-I vibrations of model dipeptides with secondary structure sensitivity and amino acid residue specificity, and its application to amyloid β-peptide in aqueous solution
Autor: Jia Liu, Cai Kaicong, Siyi Yan, Guiyang Yan, Danling Zhuang, Xuan Zheng, Fenfen Du
Publikováno v: Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy. 219
Vibrational spectroscopy has been known as particularly well-suited for deciphering the polypeptide's structure. To decode structural information encoded in IR spectra, we developed amide-I frequency maps on the basis of model dipeptides to correlate

General Applicable Frequency Map for the Amide-I Mode in β-Peptides
Autor: Ren-hui Zheng, Fenfen Du, Jian-Ping Wang, Xuan Zheng, Kaicong Cai, Jia Liu, Juan Zhao
Publikováno v: The Journal of Physical Chemistry B. 120:1069-1079
In this work, a general applicable amide-I vibrational frequency map (GA map) for β-peptides in a number of common solvents was constructed, based on a peptide derivative, N-ethylpropionamide (NEPA). The map utilizes force fields at the ab initio co
