TiO2 nanowired delivery of a Chinese traditional medicine DL-3-n-butylphthalide (DL-NBP) induces profound neuroprotection in concussive head injury

Feng L., Sharma A., Sharma H.S., Yin H., Lafuenta J.V., Ozkizilcik A., Tian Z.R., Sharma A., Sharma H.S., Bethune International Peace Hospital, CN

To develop suitable therapeutic strategies for concussive brain injury (CHI), we have explored the role of a Chinese traditional medicine DL-3-n-butylphthalide (DL-NBP) in a rat model. We delivered this compound alone and also using Titanium [...]

An Electrodeposition Method for Preparing (Ni-Cu) /(Cu-Ni) Multilayers on magnesium alloy from ionic liquid

Guo J., Guo X., Guo J., Guo X., Dong J., Wang S., Gong J., Zhu R., Ding W., Shanghai Jiao Tong University, CN

Abstract A single bath of ionic liquid electrodeposition method has been developed for the preparation of (Ni-Cu)/(Cu-Ni) multilayers on AZ91D magnesium alloy. The technique has been used to make multilayers with a composition of (92.47at.%Ni-7.53at.%Cu) [...]

Detection and degradation of environmental pollutants based on Fe3O4@Au nanoparticles as surface enhanced Raman scattering (SERS) substrates

Du J., Jing C., Chinese Academy of Sciences, CN

Ever since the surface-enhanced Raman scattering (SERS) effect was discovered, it has played a significant role in the field of vibrational spectroscopy and is now finding increasing use in high-profile applications. Recently, many catalytic-active SERS [...]

Layer by layer polyelectrolyte encapsulation of satellite structured Fe3O4@SiO2-Au magnetic SERS probe for selective detection of food dyes

Sun Z., Jing C., Chinese Academy of Sciences, CN

In situ detection and identification of dyes from a complex chemical mixture presents a great challenge to analytical chemists. Au NPs were uniformly deposited on magnetic Fe3O4@SiO2 bead to form a core-satellite Fe3O4@SiO2-AuNPs (FSPA) hetero-nanostructure, [...]

Electrochemical and textural characterization of RuO2-SnO2-graphene under co-precipitation / hydrothermal conditions

Leng X., Zou J.P., Xiong X., He H.W., Central South University, CN

In this report, ternary composite of RuO2-SnO2-graphene with different input ratio of RuCl3, SnCl2 and graphene oxides were prepared by using co-precipitation / hydrothermal approaches followed by thermal treatment. SEM, TEM, and XRD were used [...]

Flower-like TiO2 Nanostructures: Synthesis,Characterization and Photocatalytic Properties
