On the Being Done of Zhuangzi's "Tao"

Journal of Shenyang University (2009)

Yingna Wang

Tao was analyzed,which is the core of Zhuangzi's idea.The way of realizing it was discussed,which is walking two ways.The using of self-adaptation and harmonizing is the key to the method of walking two ways.Only when we reach the state of self-adaptation,can we eliminate external right and wrong.That is the performing of Tao.The ideal state of Tao is doing with no bounds.When the bounds of objective reality cannot be changed,the no bounds of subjection are more important.As a result,no bounds of subjection are the radical factor of reaching the state of ideal state.Surpassing the bounds of subjection is the true state with no bounds.

Ni-Based Nanocatalyst Protected by Ultrathin Mesoporous Nitrogen-Doped Carbon Layer with Hollow Structure for the Efficient Transfer Hydrogenation of Halogenated Nitrobenzenes

Liqi Dong Zilong Liu Yingna Wang Yuanpei Lan Chaoyi Chen

It is of great scientific and industrial value to develop cheap and efficient supported non-noble metal-based catalysts for the selective hydrogenation of halogenated nitrobenzenes. In this work, hollow structure Ni-based nano-catalyst coated with ultrathin nitrogen-doped carbon layers (H-Ni@NC) have been prepared. The etching of SiO2 template before calcination and decomposition of residual Ni3Si2O5(OH)4 shell into SiO2 leads the catalysts could maintain good mechanical property and stability. The H-Ni@NC catalyst prepared at 600 oC exhibits the optimal catalytic performance for the catalytic selective hydrogenation of halogenated nitrobenzenes under mild conditions (60 oC) when using hydrazine hydrate (N2H4Â·H2O) as the reducing agent, and could maintain its catalytic properties even after 5 consecutive runs. The contrast experiments confirm that the combination of hollow structure and N-doped carbon protective layer make the catalyst show the best catalytic effect, and the synergistic effects are further discussed in detail combine with characterization analysis. In addition, this work further reveals the mechanism of Ni-based catalyst for the transfer hydrogenation of halogenated nitrobenzenes, which may provide a reference idea for the preparation of other Ni-based catalysts.

The Brief Comment on Wen Xi's Novel Creation

Journal of Jingzhou Teachers College (2001)

Yingna Wang

The paper briefly comments on Wen Xi's novel creation. In the writer's opinion, the female images about mistresses in Wen Xi's novels show some originality among female literatures in the 90's. And her novels show special angles and particular profundities, which is not noly in the notices and things about females' fortune,but also in the manifestations on characters' endocentric worlds. In addition, the language's styles of Wen Xi's novels are worth remarking.
