The LUMO electron density geometry distribution of N-TPA1 is located on the cyanoacrylic group which favour electron injection,but for N-TPA2 it is mainly concentrated on the rhodanine framework,and resulting in the position of LUMO isolated from the -COOH anchoring group due to the presence of the -CH_2- group.

由于罗丹宁乙酸基团的羰基与五元环构架间隔一个亚甲基，使得LUMO电子分布距离吸附基团远，阻碍电子经由羰基注入TiO_2导带，这是N-TPA2的敏化电池效率比N-TPA1低的原因之一。

Ve schizophrenic inpatients will be enrolled into the 6-week, randomized, double-blind trial of sarcosine monotherapy (1000~3000 mg/day, N=75) vs. risperidone (2~6 mg/d, N=75). We will measure clinical efficacy and side effects biweekly during the treatment. At the beginning and the end of the trial, we will also measure cognitive function (e.g. intellect, attention, memory, executive function), serum amino acids, expressions of mRNA (by realtime quantitative RT-PCR) and protein of NMDA-related genes (such as SHMT2, AMT, PSAT1, ASCT1, and serine racemase) in peripheral blood lymphocytes.

The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.
