Pakistani Media on Xinjiang: Development and Opportunities
Maoxia Jiang,Chunxue Yang,Heng Wu 아시아사회과학학회 2023 Jornal of Asia Social Science Vol.10 No.3
With the acceleration of globalization, the Xinjiang Uygur Autonomous Region has increasingly garnered substantial attention from the international community in recent years due to its strategic location and multiculturalism. Foreign media have been actively disseminating reports in various areas in Xinjiang, such as politics, society and economy. Among which Western media reports are often inconsistent with the actual situation. But Pakistani media often exhibit their capacity for independent thought and objective analysis. They neither blindly adhere to the viewpoints of other nations nor allow themselves to be prejudiced by the cordial China-Pakistani relations. While Pakistani media endeavor to maintain a neutral stance, aspiring to explore these subjects concerning Xinjiang in a more balanced and rational manner that transcends simplistic expressions of support or opposition. There are reasons to believe that Pakistani media bring to the international community authentic, colorful, and fascinating coverage of Xinjiang, which not only enhance people's understanding of Xinjiang but also help to build a bridge of cultural communication and to promote exchanges and cooperation between Xinjiang and the world. It is believed that there will be more and more media and countries to gain a deeper understanding of Xinjiang and engage in more extensive exchanges and cooperation with the region in the future to promote harmony, development, and prosperity here.

Electrochemical Behaviors of Hydroquinone on a Carbon Paste Electrode with Ionic Liquid as Binder
Wei Sun*,Qiang Jiang,Maoxia Yang,Kui Jiao 대한화학회 2008 Bulletin of the Korean Chemical Society Vol.29 No.5
In this paper the electrochemical behaviors of hydroquinone (H₂Q) were investigated on a carbon paste electrode using room temperature ionic liquid N-butylpyridinium hexafluorophosphate (BPPF6) as binder (IL-CPE) and further applied to H₂Q determination. In pH 2.5 phosphate buffer solution (PBS), the electrochemical response of H₂Q was greatly improved on the IL-CPE with a pair of well-defined quasi-reversible redox peaks appeared, which was attributed to the electrocatalytic activity of IL-CPE to the H₂Q. The redox peak potentials were located at 0.340 V (Epa) and 0.240 V (Epc) (vs. the saturated calomel electrode, SCE), respectively. The formal potential (E0') was calculated as 0.290 V and the peak-to-peak separation (DEp) was 0.100 V. The electrochemical parameters of H₂Q on the IL-CPE were further calculated by cyclic voltammetry. Under the selected conditions the anodic peak current was linear with H₂Q concentration over the range from 5.0 10-6 to 5.0 10-3 mol L-¹ with the detection limit as 2.5 10-6 mol L-¹ (3s ) by cyclic voltammetry. The proposed method was successful applied to determination of H2Q content in a synthetic wastewater sample without the interferences of commonly coexisting substances.

Electrochemical Behaviors of Hydroquinone on a Carbon Paste Electrode with Ionic Liquid as Binder
Sun, Wei,Jiang, Qiang,Yang, Maoxia,Jiao, Kui Korean Chemical Society 2008 Bulletin of the Korean Chemical Society Vol.29 No.5
In this paper the electrochemical behaviors of hydroquinone ($H_2Q$) were investigated on a carbon paste electrode using room temperature ionic liquid N-butylpyridinium hexafluorophosphate ($BPPF_6$) as binder (ILCPE) and further applied to $H_2Q$ determination. In pH 2.5 phosphate buffer solution (PBS), the electrochemical response of H2Q was greatly improved on the IL-CPE with a pair of well-defined quasi-reversible redox peaks appeared, which was attributed to the electrocatalytic activity of IL-CPE to the $H_2Q$. The redox peak potentials were located at 0.340 V (Epa) and 0.240 V (Epc) (vs. the saturated calomel electrode, SCE), respectively. The formal potential ($E^0$') was calculated as 0.290 V and the peak-to-peak separation (${\Delta}E_p$) was 0.100 V. The electrochemical parameters of $H_2Q$ on the IL-CPE were further calculated by cyclic voltammetry. Under the selected conditions the anodic peak current was linear with $H_2Q$ concentration over the range from $5.0\;{{\times}}\;10^{-6}$ to $5.0\;{\times}\;10^{-3}\;mol\;L^{-1}$ with the detection limit as $2.5\;{\times}\;10^{-6}\;mol\;L^{-1}$ (3$\sigma$ ) by cyclic voltammetry. The proposed method was successful applied to determination of $H_2Q$ content in a synthetic wastewater sample without the interferences of commonly coexisting substances.
