Transparent conducting oxide (TCO) based on indium doped zinc oxide films in the nano scale were successfully prepared using combination between dip coating and thermal decomposition process. Structural investigations confirm the polycrystalline ZnO hexagonal wurtzite phase grown along the c-axis with nano crystallite size about 10 nm. morphology investigation shows that ZnO films consist of fine grains of average size 40 nm. This indicates that each grain contains several crystallites with different orientations. Cross sectional image presents good adhesion of the films with the substrate and the film thickness has been determined. Compositional analysis detects the indium content in the host ZnO matrix, the In/Zn ratio is close to the calculated concentration ratios of the precursor. The optical transmittance shows that the films are transparent in the UV and VIS-IR spectral region and interference fringes were observed to be thickness dependent. Preparation parameters were investigated and optimized such as dipping rate, number of deposition cycles, precursor concentration, annealing process and In/Zn ratio. Optimization process was investigated for low resistivity, high optical spectral window transmission and easy preparation process. Dipping rate in the range 2 - 38 mm/s is the most suitable range for good film quality while dipping rate range 30 - 38 mm/s produces thicker films in lower deposition cycles. The higher dipping rate produces films with lower transparency (milky films) while the small deposition rate rate requires large number of deposition cycles in order to increase the thickness. Besides, the higher dipping rate reflects lower resistivity of the deposited films. Precursor molar concentration was observed to have an essential effect on the film thickness, film quality and transparency. Lower precursor concentration requires also large number of deposition cycles for thickening the films. The higher concentration results also milky films (high sc

日粮中添加外源性酶在促进家禽生长和提高饲料利用率方面的价值已得到业界一致认可。近年黄玉米价格高涨,部分饲料生产商选用小黑麦、小麦、大麦或高粱等营养价值较低的其他原料来替代黄玉米。这些作物富含非淀粉多糖(non-starch polysaccharides,NSPs),而饲料中NSPs的含量与其营养价值呈反比。日粮中添加酶可以提高富含可溶性NSPs作物的营养价值。大量研究表明,在小麦、大麦、高粱或小黑麦型日粮中添加外源性酶,家禽可以获得与采食玉米-大豆型日粮相当的生产性能。家禽的胃肠道可以分泌酶来帮助营养物质消化,但其分泌的酶由于数量有限还不足以完全消化纤维,需要在日粮中额外添加一些商用外源性酶来提高消化能力。在家禽饲料中使用商用酶的优点包括提高家禽生产性能和饲料利用率,通过减少粪便中的养分最大限度地减少环境污染。本文综述了酶的用途及其在家禽生产中的应用。此外,本文证明外源性酶是研究代谢和生理机制的一种非常重要的因素。这些数据将提高我们对商用酶在家禽饲料中作用的理解。

The reaction of 1-methylisoquinoline 1 with hy-drazonoyl halides 2 in ethanol in the presence of chitosan under microwave irradiation affords triazoloisoquinoline 4. Product 4 reacts with dimethylformamide-dimethylacetal to give ena- minones 7 which react with hydrazonoyl halides to give pyrazolyl triazoloisoquinoline 13. Also, 1-methylisoquinoline 1 reacts with arylisothio-cyanate to give thioanilide 15 which reacts with hydrazonoyl halides to give the corresponding thiadiazolyl isoquinoline derivatives 20, 24.
