Improvement in Cr Nanoparticle Content in Ni-Cr Film by Co-deposition with Combined surfactant HPB and CTAB

引用

Acta Metallurgica sinica(English Letters) 2017年第10期30卷 999-1007页

作者： Li-juan Qin Yuan-Chao Huang Laboratory for Corrosion and Protection Institute of Metal ResearchChinese Academy of Sciences College of Material science and Engineering University of Science and Technology of China

The effects of single surfactant hexadecylpyridinium bromide（HPB） and cetyltrimethylammonium bromide（CTAB） and the combination of HPB and CTAB on the Cr nanoparticle content in the Ni-Cr film prepared by codeposition were investigated. single HPB/CTAB addition inhibited the oxidation and amorphous transformation of the Cr nanoparticles in the plating bath and effectively stabilized the Cr nanoparticles content at approximately 10 mass% as a function of time. Moreover, the combination of HPB and CTAB formed a cylindrical micelle structure on the Cr nanoparticle surface, which prompted the formation of a layer of NiCr2O4. As a result, the Cr nanoparticle content increased sharply to 20 mass%.

Heat Treatment of Cold-Rolled Low-Carbon si-Mn Dual Phase steels

引用

Journal of Iron and steel Research International 2010年第1期17卷 54-58页

作者： LUO juan-juan sHI Wen HUANG Qun-fei LI Lin Material science and Engineering College Shanghai University Shanghai 200072 China

The effects of overageing （OA） and vanadium addition on microstructure and properties of cold-rolled lowcarbon si-Mn dual phase （DP） steel sheets are studied. The results show that the microstructure and mechanical properties of DP steels are greatly affected by OA temperature. When OA is done at low temperatures （473 -- 573 K）, the elongation rate increases sharply while both the yield strength and tensile strength decrease significantly, When OA is done at high temperatures （〉573 K）, the elongation does not further increase, but the yield strength increases and tensile strength decreases, which deteriorates the mechanical properties of the steel. The results also show that both the strength and the tempering stability can be significantly improved by vanadium microalloying. Finally, the optimum OA temperature for the traditional steel appears to be around 523 K, while it is around 573 K for the V-containing steel, resulting in the best overall mechanical properties.

Cooper instability and superconductivity of the Penrose lattice

science China(Physics,Mechanics & Astronomy) 2022年第8期65卷 110-120页

作者： Yu-Bo Liu juan-juan Hao Yongyou Zhang Ye Cao Wei-Qiang Chen Fan Yang school of Physics Beijing Institute of TechnologyBeijing100081China Department of Physics Southern University of Science and TechnologyShenzhen518055China shenzhen Institute for Quantum science and Engineering Southern University of Science and TechnologyShenzhen518055China shenzhen Key Laboratory of Advanced Quantum Functional Materials and Devices Southern University of Science and TechnologyShenzhen518055China

Bulk superconductivity(sC) has recently been observed in the Al-Zn-Mg quasicrystal(QC). To settle several fundamental issues of the sC on the QC, we use an attractive Hubbard model to perform a systematic study on the Penrose lattice. The first issue is the Cooper instability of the QC, i.e., no Fermi surface under an infinitesimal attractive interaction. starting from the two-electron problem outside a filled Fermi sea, we analytically prove that an infinitesimal Hubbard attraction can lead to the Cooper instability as long as the density of the state is nonzero at the Fermi level. The findings provide a basis for the sC on the QC. Our numerical results show that the Cooper pairing always takes place between two time-reversal states, satisfying Anderson’s theorem. On this theorem, we perform a mean-field(MF) study at zero and finite temperatures. The MF study shows that an arbitrarily weak attraction can lead to a pairing order, with the resulting pairing state being well described by the Bardeen-Cooper-schrieffer theory and the thermal dynamic behaviors being well consistent with the experimental results. The second issue is about the superfluid density on the QC without translational symmetry. Our findings clarify that although the normal state of the system locates at the critical point of the metal-insulator transition, the pairing state exhibits a real sC, carrying finite superfluid density that can be verified by the Meissner effect. This finding is consistent with the experiment results. This study also reveals that the properties of the sC on the Penrose lattice are universal for all QCs.

Improved stability and oral bioavailability of Ganneng dropping pills following transforming lignans of herpeto- spermum caudigerum into nanosuspensions

引用

Chinese Journal of Natural Medicines 2018年第1期16卷 70-80页

作者： LI juan-juan CHENG Ling sHEN Gang QIU Ling sHEN Cheng-Ying ZHENG juan XU Rong YUAN Hai-Long Department of Pharmacy Air Force General Hospital of PLA Beijing 100142 China Department of Pharmacy Guangyuan Central Hospital Guanyuan 628000 China Department of Pharmacy Shuangliu District Maternal and Child Health Hospital Chengdu 610075 China Chengdu Institute of Chinese Herbal Medicine Chengdu 610045 China

The present study was designed to improve storage stability and oral bioavailability of Ganneng dropping pills(GNDP) by transforming lignans of Herpetospermum caudigerum(HL) composed of herpetrione(HPE) and herpetin(HPN) into nanosuspension(HL-Ns), the main active ingredient of GNDP, HL-Ns was prepared by high pressure homogenization and lyophilized to transform into solid nanoparticles(HL nanoparticles), and then the formulated HL nanoparticles were perfused into matrix to obtain Ns-GNDP by melting method. For a period of 3 months, the content uniformity, storage stability and pharmacokinetics test in vivo of Ns-GNDP were evaluated and compared with regular GNDP at room temperature. The results demonstrated that uniformity of dosage units of Ns-GNDP was acceptable according to the criteria of Chinese Pharmacopoeia 2015 J. Physical stability of Ns-GNDP was investigated systemically using photon correlation spectroscopy(PCs), zeta potential measurement, and scanning electron microscopy(sEM). There was a slight increase in particles and PI of HL-Ns re-dispersed from Ns-GNDP after storage for 3 months, compared with new formulated Ns-GNDP, which indicated a good redispersibility of the Ns-GNDP containing HL-Ns after storage. Besides, chemical stability of Ns-GNDP was studied and the results revealed that HPE and HPN degradation was less when compared with that of GNDP, providing more than 99% of drug residue after storage for 3 months. In the dissolution test in vitro, Ns-GNDP remarkably exhibited an increased dissolution velocity compared with GNDP and no distinct dissolution difference existed within 3 months. The pharmacokinetic study showed that HPE and HPN in Ns-GNDP exhibited a significant increase in AUC0–t, Cmax and decrease in Tmax when compared with regular GNDP. These results indicated that Ns-GNDP possessed superiority with improved storage stability and increased dissolution rate and oral bioavailability.
